  8. 8. PROJECT TITLE TO INCREASE THE PRODUCTION OF PRESS SHOP WITH THE HELP OF GANGING OF DIES. ABSTRACT Now a days we see industry works on 6 factors. These factors are very much responsible for the growth of a industry. These are 1) Safety 2) Productivity 3) Quality 4) Cost 5) Delivery 6) Moral But here in this project we are concentrating on only on factor i.e. increase in productivity. Here we are using a method of ganging of dies in which two similar dies are mounted on a press machine. This help us reduction of productivity time. Which will enhance the productivity. So this method is very much effective in increase the productivity of the material. This is cost and time saving method which will help in the betterment of the industry. PART NO.-DZ161013 PART NAME : GUSSET HEAD THEORY:- Here the work is done on 250T press machine. In the production of gusset head there are mainly 4 steps are involved. These processes are also shown in table according to there steps. Suitable dies are used with respect to the process followed. Gusset head is generally a BAJAJ part which are used in platina bikes. These parts gives the support to the engine. The pictorial view of gusset head is shown in the figure which is given below.
  9. 9. METHODOLOGY:- 1. First step all the sheets of metal is procured from the vendor. 2. The grade of the material is checked by the inspection department. In inspection these three things are checked. Wrong size of the metal sheet, grade of the metal sheet and the visual defects of the metal sheet. 3. Now the first operation is to be performed i.e. Blanking. It is done to extract the profile sheet from the metal sheets. In this the operation the profile sheet should be according to our need . it should be dent, scratch and burr free. 4. Second operation which to be performed is Forming. In this draw is done on the blanked profile sheet. In this operation complete bend should be done, scratch should be taken care of through oiling, crack/ thinning should be regularly checked. 5. After this Piercing is to be performed. It a type of operation which is totally opposite of blanking. In this pierced profile sheet is avoided rest is considered. Dimension of us/os has to be maintained,& location of hole should not be displaced. 6. Last step is Bending and Trimming. In this side part of gusset is bend and extra part of the sheet is trimmed.

  11. 11. Blanking- FORMING
  12. 12. Piercing Bending- NOW IF APPLY 2 DIES IN SAME PRESS THEN THE OPERATION CAN BE PERFORMED AT FASTER RATE TO USE GANGING OF DIES THE FOLLOWING THINGS SHOULD BE TAKEN INTO CONSENDERATION
  13. 13. 1. Power of the press. 2. Size of the bluster bed. 3. Size of the dies. 4. Shut height of the die. 5. Shut height of the press. 6. Tonnage required for the die. Now let’s assume that the die is having the same shut height and is between in given range of shut height of the press. Condition for dies are :- Length – 910mm Shut height -650mm Width – 500mm Now consider we are having a press which is having the bluster bed which can accommodate approximately 2 dies. We are having such presses in our industry. CALCULATION :- (Cost Estimation) Procurement for the metal sheet- 45 rupees per kg Dimensions of sheet -1230x260mm Weight of on sheet- 1.020 kg Thickness of the sheets- 1.5mm Scraps cost -25 rupees per kg Generally cost is estimated with the help of 5 M. These are 1. Man 2. Machine 3. Material 4. Management 5. Method
  14. 14. but as per general idea we are calculating as cost 2 rupees per strokes ignoring all the all other hidden cost. Now according to table Cost estimated for blanking- 2x150=Rs300 Cost estimated for forming- 2x160=Rs320 Cost estimated for percing-2x170=Rs340 Cost estimated for bending-trimming- 2x180=Rs360 Total cost-Rs1320 This is a rough calculated cost in this hidden cost are not involved like maintainace, worker availability etc. are not included. Now if re plan our process and mount 2 dies in one press For example Blanking and forming at a time in a single press having different dies. This will save time as well as machine cost. And similarly at the same time piercing and bending trimming operation can be done. Now the calculation of cost Cost for blanking and forming-2x150=Rs300 Cost for piercing and bending-2x170=Rs340 Total cost=Rs640 This is a rough calculated cost in this hidden cost are not involved like maintainace, worker availability etc. are not included. Advantages of ganging of dies 1. Cost saving 2. Time saving 3. Man power saving 4. Less press machine required 5. Utility of press machine increases
  15. 15. 6. Pace of work is fast 7. Production is high Disadvantages of ganging of dies 1. Require bigger bluster bed 2. May require a dummy cushion when one die require cushion and other’s didn’t so dummy cushion is given to the second die in order to balance it. 3. Tonnage of press should be greater or equal to the die required. 4. Shut height of both the dies should be same and should be in press shut height range. Conclusion of Project This method is very much effective in increasing the production rate. This works quite efficiently. By using this method we can cover some parameter which is very much important for every industry.
  16. 16. Dies and its Types: Die: The die may be defined as the female part of a complete tool for producing work in a press. It is also referred to a complete tool consists of a pair of mating members for producing work in a press. Types of dies: The dies may be classified according to the type of press operation and according to the method of operation. (A): According to type of press operation: According to this criterion , the dies may be classified as cutting dies and forming dies. 1: Cutting Dies: These dies are used to cut the metal. They utilize the cutting or shearing action. The common cutting dies are : blanking dies , perforating dies , notching dies , trimming , shaving and nibbling dies. 2: Forming Dies: These dies change the appearance of the blank without removing any stock. Theses dies include bending, drawing and squeezing dies etc. (B) According to the method of operation: According to this criterion, the dies may be classified as : single operation or simple dies , compound dies , combination dies , progressive dies , transfer dies and multiple dies. 1: Simple Dies: Simple dies or single action dies perform single operation for each stroke of the press slide. The operation may be one of the operation listed under cutting or forming dies. 2: Compound Dies: In these dies, two or more operations may be performed at one station. Such dies are considered as cutting tools since, only cutting operations are carried out. Figure shows a simple compound die in which a washer is made by one stroke of the press. The washer is produced by simulation blanking and piercing operations. Compound dies are more accurate and economical in production as compared to single operation dies.
  17. 17. 3: Combination Dies: In this die also , more than one operation may be performed at one station. It is difficult from compound die in that in this die, a cutting operation is combined with a bending or drawing operation, due to that it is called combination die. 4: Progressive Dies: A progressive or follow on die has a series of operations. At each station , an operation is performed on a work piece during a stroke of the press. Between stroke the piece in the metal strip is transferred to the next station. A finished work piece is made at each stroke of the press. While the piercing punch cuts a hole in the stroke , the blanking punch blanks out a portion of the metal in which a hole had been pierced at a previous station. Thus after the first stroke , when only a hole will be punched , each stroke of the press produces a finished washer.
  18. 18. 6: Transfer Dies: Unlike the progressive dies where the stroke is fed progressively from one station to another. In transfer dies the already cut blanks are fed mechanically from one station to other station. 7: Multiple Dies: Multiple or gang dies produce two or more work piece at each stroke of the press. A gang or number of simple dies and punches are ganged together to produced two or more parts at each stoke of the press.
  19. 19. HYDRAULIC AND MECHANICAL PRESSES The press represents a specific type of machine tool, essential in the performance of industrial manufacturing processes. Presses deliver energy through a force that acts over a distance or stroke. One important application is in metal forging manufacture. The energy of the press is used to close the die, forging the part within. Press machine tools apply force/energy to the work differently than drop hammers, (that deliver energy to the work through a collision), hammers are the other class of machine tools used to forge metal parts. Drop hammers are covered on the previous page. This page will cover different types of press machines, their function, and capabilities, although it is located in the metal forging section, forging is only one class of manufacturing processes that employ presses. Press machines are also the primary machine tool used in metal extrusion and sheet metal fabrication processes. Hydraulic and mechanical presses are employed during sheet metal forming to the extent that sheet metal processes, in general, are often referred to as press working. Presses may be used in the manufacture of plastic parts. Machining operations, such as broaching, may also require presses. Press machine tools vary in size and in the amount of force they can output. The energy from a press is often used to do work requiring a tremendous amount of force, such as a large amount of plastic deformation of a sizable piece of metal. The method and nature by which a press machine will deliver its energy will vary, dependent on its type. Machine presses shown here are vertical, meaning that the force vector is up and down relative to gravity. In many cases these same machine types are utilized horizontally, meaning the force is delivered in a path perpendicular to the direction of the force of gravity. If the force be exerted
  20. 20. vertically, horizontally, or at some intermediate angle, the working principles of each type of machine tool are the same. Press machine tools are of two main types, hydraulic presses and mechanical presses. Selection of a type of machine press depends on the factors of the manufacturing process. The first consideration would be the basic type of process the press tool will be employed to perform. For example, a press for metal forging, a press for extrusion, a press for impact extrusion, or a press for sheet metal working will all have different general requirements. The next very important factor in machine press selection for a manufacturing operation is the press capacity required. Required press capacity is likely related to the size of the work stock, and type of process. Length of stroke over which the press delivers force is another primary factor when choosing a press machine tool, this also will be related to the basic type of process being employed. These initial considerations should give an immediate idea of the general type of press required. After this, all the specific factors of the manufacturing process should be weighed, to determine the best choice for a press machine tool. Hydraulic Presses Hydraulic presses are a powerful class of machine tools, they derive the energy they deliver through hydraulic pressure. Fluid pressure, in a particular chamber, can be increased or decreased by the use of pumps, and valves. Sometimes devices and systems may be used to increase the capacity of the pumps in more powerful presses. These presses can operate over a long distance and at a constant speed. Hydraulic presses are generally slower relative to other press machine types. This involves longer contact with the work, therefore the cooling of the work can be an issue when hot forming a part with hydraulic force. Hydraulic presses are capable of being the most powerful class of presses. Some may be as large as buildings, and can deliver awesome pressure. The largest hydraulic presses are capable of applying 75,000 tons, (150,000,000 lbs), of force. The hydraulic press shown is being used to manufacture a metal forging. Extrusion is also a very common use for such a press, although extrusion is often performed horizontally.
  21. 21. The basic working principles of the hydraulic press are simple, and rely on differences in fluid pressure. Fluid is pumped into the cylinder below the piston, this causes the fluid pressure under the piston to increase. Simultaneously, fluid is pumped out of the top channel, causing the fluid pressure above the piston to decrease. A higher pressure of the fluid below the piston than the fluid above it causes the piston to rise. In the next step, fluid is pumped out from below the piston, causing the pressure under the piston to decrease. Simultaneously, fluid is pumped into the cylinder from the top, this increases the fluid pressure above the piston. A higher pressure of the fluid above the piston, than the fluid below it, moves the piston downward. Mechanical Presses Mechanical presses belong to a class of machine tools that encompass a wide range of different machine types. Primarily, the mechanical press transforms the rotational force of a motor into a translational force vector that performs the pressing action. Therefore, the energy in a mechanical press comes from the motor. These types of presses are generally faster than hydraulic or screw presses, (actually the screw press may also be classified as a mechanical press). Unlike some presses, in a mechanical press, the application of force varies in both speed and magnitude throughout the distance of the stroke. When performing a manufacturing operation using a mechanical press, the correct range of the stroke is essential. Presses are chosen based on the characteristics of the manufacturing process. Mechanical press machine tools are commonly used in metal forging manufacture, and sheet metal working. The desired application of force will dictate the type of machine required. Extrusion will often necessitate a more consistent force over a longer distance. However, a mechanical press may often be a good choice for impact extrusion, since a fast, quickly repeatable application of force
  22. 22. over a limited distance is what is needed for that type of manufacturing process. The most powerful mechanical presses in modern manufacturing industry will have a press capacity of about 12,000 tons, (24,000,000 lbs).
  23. 23. SHEET METAL WORKING 1. Introduction Sheet metal is simply metal formed into thin and flat pieces. It is one of the fundamental forms used in metalworking, and can be cut and bent into a variety of different shapes. Countless everyday objects are constructed of the material. Thicknesses can vary significantly, although extremely thin thicknesses are considered foil or leaf, and pieces thicker than 6 mm (0.25 in) are considered plate. 2. Sheet metal processing The raw material for sheet metal manufacturing processes is the output of the rolling process. Typically, sheets of metal are sold as flat, rectangular sheets of standard size. If the sheets are thin and very long, they may be in the form of rolls. Therefore the first step in any sheet metal process is to cut the correct shape and sized ‘blank’ from larger sheet. 3. Sheet metal forming processes Sheet metal processes can be broken down into two major classifications and one minor classification  Shearing processes -- processes which apply shearing forces to cut, fracture, or separate the material.  Forming processes -- processes which cause the metal to undergo desired shape changes without failure, excessive thinning, or cracking. This includes bending and stretching.  Finishing processes -- processes which are used to improve the final surface characteristics. 3.1 Shearing Process 1. Punching: shearing process using a die and punch where the interior portion of the sheared sheet is to be discarded. 2. Blanking: shearing process using a die and punch where the exterior portion of the shearing operation is to be discarded. 3. Perforating: punching a number of holes in a sheet 4. Parting: shearing the sheet into two or more pieces 5. Notching: removing pieces from the edges
  24. 24. 6. Lancing: leaving a tab without removing any material Fig.1Shearing Operations: Punching, Blanking and Perforating 3.2 Forming Processes  Bending: forming process causes the sheet metal to undergo the desired shape change by bending without failure. Ref fig.2 & 2a  Stretching: forming process causes the sheet metal to undergo the desired shape change by stretching without failure. Ref fig.3  Drawing: forming process causes the sheet metal to undergo the desired shape change by drawing without failure. Ref fig.4  Roll forming: Roll forming is a process by which a metal strip is progressively bent as it passes through a series of forming rolls. Ref fig.5

  26. 26. Fig.4 Schematic of the Drawing process. Fig.5 Eight-roll sequence for the roll forming of a box channel 3.3 Finishing processes Material properties, geometry of the starting material, and the geometry of the desired final product play important roles in determining the best process
  27. 27. 4. Equipments Basic sheet forming operations involve a press, punch, or ram and a set of dies. 5.1 Marking and measuring tools  Steel Rule - It is used to set out dimensions.  Try Square - Try square is used for making and testing angles of 90degree  Scriber – It used to scribe or mark lines on metal work pieces.  Divider - This is used for marking circles, arcs, laying out perpendicular lines, bisecting lines, etc. Fig.9 Marking and measuring tools Cutting Tools  Straight snip - They have straight jaws and used for straight line cutting.  Curved snip - They have curved blades for making circular cuts. Striking Tools  Mallet - It is wooden-headed hammer of round or rectangular cross section. The striking face is made flat to the work. A mallet is used to give light blows to the Sheet metal in bending and finishing. Ref fig.11
  28. 28. Fig.11 Types of Mallets 6. Merits  High strength  Good dimensional accuracy and surface finish  Relatively low cost 7. Demerits  Wrinkling and tearing are typical limits to drawing operations  Different techniques can be used to overcome these limitations o Draw beads o Vertical projections and matching grooves in the die and blank holder  Trimming may be used to reach final dimensions 8. Applications  Roofings  Ductings  Vehicles body buildings like 3 wheelers, 4 wheelers, ships, aircrafts etc.  Furnitures, House hold articles and Railway equipment.
  29. 29. CONCLUSION It’s always a great opportunity to experience the valuable exposure of an industry. There is lot of difference between the Theories and Practices.
