Introduction
• One of the earliest common machine tools is the
hydraulic press. It is a machine press that uses
a hydraulic cylinder to generate compressive
force. It uses hydraulics to mimic a mechanical
lever and was also known as a Bramah press
after its English designer, Joseph Bramah.

4
Introduction Cont.
• Modern hydraulic presses can sometimes be
more effective in settings where mechanical
presses have historically been more common.
The performance and dependability of
modern hydraulic presses is good.

5
Introduction Cont.
• The ability of hydraulic presses to perform
has been improved by new fast acting valves,
electrical components, and more effective
hydraulic circuits. Forging, clinching, molding,
punching, deep drawing, and metal forming
processes are frequently performed with
hydraulic presses.

6
Introduction Cont.
• Compression tests are used to analyze how a product
or material responds to compression, squashing,
crushing, or flattening by evaluating how the
material behaves under a compressive stress. It
gives information on the integrity and safety of
materials and products, assisting manufacturers in
ensuring that their completed goods are fit for
purpose and produced to the highest standards.

7
Problem Statement

 Hydraulic cylinder
A hydraulic cylinder, also known as a linear hydraulic motor, is a
type of mechanical actuator that delivers a single force during a
single stroke. Pressurized hydraulic fluid, which is commonly oil,
provides the hydraulic cylinders with their power. A piston and
piston rod coupled to a cylinder barrel make up the hydraulic
cylinder, which oscillates back and forth.

21
 Hydraulic Hand Pump
A hydraulic hand pump uses direct personal effort to transfer
hydraulic fluid under pressure. It is an apparatus that transforms
mechanical energy into hydraulic energy (hydrostatic energy i.e.,
flow, pressure). It produces flow with sufficient force to
counteract the pressure brought on by the load at the pump
outlet.

22
 Pressure Gauge
A pressure gauge is a mechanical instrument designed to measure
the internal pressure and/or vacuum of a vessel or system.
Pressure Gauges are offered in a variety of styles, sizes, and
wetted part materials to meet the demands of standard and special
applications

23
 Steel Frame
The hydraulic cylinder, hydraulic hand pump, and pressure gauge
are all supported by this frame. The upper cross beam, heel block,
setting plate, upper plate, and under plate make up the frame,
along with the post, press bed frame, base section, and lower
cross member. Bolts, nuts, washers, and lock washers are used to
secure the various components together.

24
TEST PROCEDURES
1) The samples are cut into a cylindrical shape, all having equal diameter and length, so as to have
an equal area.
2) The sample is place on the hydraulic press, in between the heel block and serrated saddle
3) Two g-clamps are used to hold the heel block against the press bed frame.
4) The handle is pressed continuously until the sample is held firmly between the heel block and serrated
saddle.
5) The handle is then pressed slowly to apply pressure on the sample, the reading on the pressure gauge is
simultaneously recorded with each press of the handle.
6) The previous step is carried out until the material starts to deflect.
7) The point at which the material deflects is the yield point.

CONCLUSIONS
• The compression test carried out was able to determine the yield stress
of the three samples of brass, carbon steel and aluminium. This test
showed that aluminum has low strength while carbon steel and brass have
high strength i.e., they can both withstand high pressures and stresses.
• The hydraulic press can be used for various operations in the workshop
as long as they involve compression or compressing materials.

32
RECOMMENDATION
• This compression test should be implemented in every material
production industry so as to be able to determine the maximum stress
the material can withstand before it deflects.
• The hydraulic press should be implemented into the mechanical
engineering world because it makes works that involve high pressure to
be performed easily and quickly.
• It is also recommended that the safety precaution be followed while
performing the compression test.
