Transcript of "Baixie plc forging hammer and its forming technique of multi pieces forged by one-mould"

  1. 1. Baixie PLC Forging Hammer and its Forming Technique of multi-pieces forged by one-mouldAbstract: Cost curbing and efficiency improvement is the eternal theme of technical improvement of forgingenterprises. Baixie always regards “providing service for the industry and creating values for our guests” as thesignificant task. Year after year, we make progress and grow shoulder to shoulder with our guests. We haveaccumulated abundant practical and theoretical experience and have achieved a lot through the application of PLCforging hammers and one mould several parts forming technique, through cutting production process, reducingresources consumption, improving working condition, raising production efficiency, up-grading forgings’ qualityand so on.Key words: PLC forging hammer; one mould several parts; flexibility; multi-impression die1 The Technique Advantages of One Mould life several times over.

Thefacilitating metal forming process and cutting down layout of the work pieces can be opposite vertex,the technique process. interlock, parallel or many other Reduce mould consumption.

  2. 2. strength. Groove gap, which is usually half to one time of groove depth, should be determined by the difficulty of forging forming. The easier the forming is, the smaller the gap should be. When choose one mould several parts forming, high-accuracy forging processing equipment (e.g. CNC milling) should be equipped to guarantee position accuracy between forging grooves. In one mould several parts forming, the gap between two grooves is relatively small, if side-cutted all parts at the same time, it would be very difficult because the rigidity of cavity plate is relatively weak. So, side cutting for one part each time is usually adopted. When design cavity plate, attention should be Interlock layout paid to demise, or it would cause damage to work pieces. Parallel layout At the same time, such factors as shorteningtechnique process, improving material utilization,simplifying forming process, expanding mould life,up-grading mould quality, convenient to operate andeasy to form and other factors should be taken intooverall consideration. One mould several parts forming usually adoptssingle heat through multi-cavity,multi-technique-process. Some use professionalmachine such as roll forging and cross wedge rolling One mould two parts three-mode cavity forgingto blank, and distribute blank with roughly the samevolume of forgings through raw materials reallocationand then through bend hitting, pre-forging,end-forging to accomplish forming. One mould several parts forming, cavity needs toanalyze forging’s shape to choose proper layout forms;if condition permitted, choose as shallow point ofgroove as possible at the boundary of cavities to avoidforging deformation when forming, so as to reducegap, that is to say to save material and reduce forming One mould two parts connecting rod two-mode cavity forging

Besides, striking energy and frequency can bePLC Forging Hammer adjusted through PLC system to meet different work It is well-known that forging hammer is a kind of pieces’ forging technique. Operating terminals allforming equipment with simplest structure, best instructed in Chinese, which lower the requirement toadaptability, and moderate purchasing cost. Its greatest operators; unmanned operation can be realizedadvantage in forging’s forming process lies in its fast through interaction with robots. Forging hammer isforming speed, high hitting frequency, and ability to the core equipment in the forging production line. Itswithstand partial strike. High efficiency, flexibility, automation determines the automation of the wholeand fast speed are the main technique features for production line.forging hammers being widely used.
