Abstract

The invention discloses a shifting fork bush plate material slicing die. The die comprises a lower punching die and an upper punching die, wherein the lower punching die comprises a lower lining plate, a blanking female die and a positioning block, and the upper punching die comprises an upper lining plate, a blanking male die and a reset plate. According to the die, the problem that the plate material of the shifting fork bush is not provided with a special slicing die so that integral slicing machining can not be carried out is solved, through the corresponding arrangement of the blanking female die and the blanking male die, the shifting fork bush plate material can be fixed and positioned during punching, hole punching positioning is accurate, the machining quality is good, the machining procedures are reduced by adopting one-time integral stamping, loading and unloading are convenient, and the machining efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of mechanical processing, in particular to a die for slicing a shift fork bush sheet material. Background technique [0002] The fork is a part of the car gearbox. It is connected to the shift handle and is located at the lower end of the handle. The middle shift wheel is moved to change the input / output speed ratio. The shift fork is mainly used for clutch shifting. In order to prolong the service life, the shift fork is usually It needs to be used with the bushing. The shift fork bushing is a vulnerable part and requires a lot of processing. The initial material of the shift fork bushing is a rectangular piece. The existing processing technology needs to use a single-piece knife to divide the material into two processes on the IOT punch when cutting the piece, that is, process the wide side and long side of the piece separately. The disadvantage of this process is that it is troublesome to load and unload...
