Technical field
The present invention relates to diel, particularly relate to a kind of decompressor for buffer support of rear shock absorber of automobile.
Background technology
The arcuate structure of the buffer support of rear shock absorber of automobile is complicated, usually casting technique is taked to obtain blank, carry out deep processing with lathe, drilling machine again and finally just can obtain required parts, because this parts arc area is more and higher and just can complete the processing of whole workpiece because workpiece needs repeatedly reverse side to clamp in lathe process arc process to the requirement of radian, so the final Product Precision formed is inadequate, the low energy consumption of this processing technology efficiency is high simultaneously, high to the operation requirements of technical staff.
Summary of the invention
For the defect existed in prior art or deficiency, technical problem to be solved by this invention is: provide a kind of decompressor for buffer support of rear shock absorber of automobile, can solve production process complexity, the part dimension precision produced is not high, production efficiency is low inferior.
To achieve these goals, the technical scheme that the present invention takes is for providing a kind of decompressor for buffer support of rear shock absorber of automobile, comprise upper bolster, die shoe, backing plate is disposed with below described upper bolster, upper mounting plate, stripper, die, lower installation board, die shank is provided with in the middle part of described upper bolster, be provided with in the middle of described die shank and make bar, described upper bolster, described backing plate, described upper mounting plate is equipped with unloading bolt, described unloading bolt bilateral symmetry is provided with the first straight pin, described bar of beating connects punch-die by the second straight pin, fusion gold is housed in the middle of described punch-die, fixing pin stop is provided with above described push rod, ejector is provided with below described punch-die, punch is provided with below described ejector, described die shoe is fixed between described lower installation board and described die by the first screw, described upper bolster is fixed between described backing plate and described upper mounting plate by three cylindrical pin and the second screw.
As a further improvement on the present invention, offer through hole in described punch, described ejector is arranged in described through hole.
As a further improvement on the present invention, the profile of described punch is cylindrical.
As a further improvement on the present invention, the cross section of described stripper is annular.
As a further improvement on the present invention, described punch is socketed in die in punching course, and relative sliding.
As a further improvement on the present invention, described decompressor also comprises guide pin bushing and guide pillar, and described guide pin bushing is fixed on upper bolster, and described guide pillar is fixed on die shoe, and described guide column sleeve is connected to also can relative sliding in guide pin bushing.
The invention has the beneficial effects as follows: the decompressor of this buffer support of rear shock absorber, the buffer support of rear shock absorber that well can realize external form complexity utilizes the blanking of punch press and shaping, disposablely in a device to complete, a large amount of operation and production cost are saved, both enhanced productivity, in turn ensure that product quality.And cheap for manufacturing cost, the economy and durability of this decompressor.
