Description
Technical field
The present invention relates to technical field, particularly relate to upper end cover stretching device before a kind of electric automobile damper.
Background technology
The complicated structure of upper end cover before electric automobile damper, product fineness requires higher, and traditional handicraft adopts manual cutting to be processed into, and product percent of pass is low, and processing work efficiency is low; Underproof product also needs to reprocess, and processes further, cuts, polishes, the operation such as panel beating to it, wastes time and energy.
When particularly stretching to workpiece, artificial stamper stretching operation is wasted time and energy, and yield rate is low; And not easily take off, if adopt powerful pickup easily to cause workpiece damage in workpiece embedding mould.
Summary of the invention
Adopt and mechanical integrated added to upper end cover before electric automobile damper man-hour, be mainly divided into three steps: blanking, stretching and punch forming; The object of the invention is the technological deficiency for existing in prior art, and provide a kind of time saving and energy saving, the stretching device of upper end cover before automation processing electric automobile damper.
The technical scheme adopted for realizing object of the present invention is: upper end cover stretching device before electric automobile damper, it is characterized in that comprising mould assembly and lower mould assembly; Described upper mould assembly comprises cope match-plate pattern, die block, die shank, knockout rod and die; Be fixedly connected with described die block below described cope match-plate pattern, above described cope match-plate pattern, described die shank be housed; Be fixedly connected with die below described die block, the center of described die has a circular groove; Described knockout rod, cope match-plate pattern, die block and die have a hole supplying knockout rod to pass from top to bottom until the circular groove of die; Described lower mould assembly comprises lower bolster, punch retainer, punch, is fixed with punch retainer above described lower bolster, and the cross section that is fixed with above of described punch retainer is circular punch, and the surrounding of described punch is pressing plate; Described pressing plate is provided with annular groove, and annular groove is identical with the apparent height of punch, and the upper surface of annular groove and punch forms circular groove; Spring-rubber is provided with between described pressing plate and punch retainer; The diameter of the circular groove of described die is greater than the diameter of section of described punch.
Guide pillar is equipped with in the side of described lower bolster, and the guide pin bushing be connected with described guide pillar is equipped with in the side of described cope match-plate pattern.
Described pressing plate, spring-rubber, punch retainer runs through alignment pin, and described alignment pin is communicated with described pressing plate, spring-rubber, punch retainer.
Operation principle of the present invention is: during work, to be first placed on by workpiece in groove that pressing plate and punch formed jointly etc. to be punched, as shown in the figure; During punching press, in the groove of punch press-in die, die extruding pressing plate, spring-rubber compresses, and now workpiece is stretched, and the A hole on workpiece is longitudinally by cross directional stretch, as figure, shown in.After punching press, upspring by workpiece by knockout rod, spring-rubber bounces back, and lower mould assembly restores to the original state.
Compared with prior art, structure of the present invention is simple, and be easy to operation, working (machining) efficiency is high, and processing cost reduces, and product percent of pass promotes greatly.
