Description
Technical field
The present invention relates to technical field, particularly relate to upper end cover punch forming 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 carrying out punch forming to workpiece, artificial pressing mold punch forming operation is wasted time and energy, and yield rate is low.
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 punch forming device of upper end cover before automation processing electric automobile damper.
Upper end cover punch forming device before electric automobile damper, is characterized in that comprising mould assembly and lower mould assembly; Described upper mould assembly comprises cope match-plate pattern, die block and die, and described die is fixedly connected with cope match-plate pattern by die block; The surrounding of described die is provided with top board, is provided with spring-rubber between described top board and die block; The top board of described die and periphery forms circular groove; The top of described cope match-plate pattern is provided with die shank, and described die shank is provided with through hole, is installed with knockout rod in through hole, and described knockout rod is communicated to the circular groove place of die; Described lower mould assembly comprises lower bolster, punch retainer and punch, and the top of described lower bolster is fixedly connected with punch retainer, and described punch retainer is fixedly connected with described punch; The upper end of described punch coordinates with the bottom punch forming of described die; , the diameter of the circular groove at described die place is greater than the upper end diameter of section of described punch.
Described lower bolster is equipped with guide pillar, and the guide pin bushing be connected with described guide pillar is equipped with in the side of described cope match-plate pattern.
Described top board, spring-rubber, die block are provided with through hole, the tie rod of hard is provided with in described through hole, described tie rod is positioned at through hole, can restraining spring rubber by the stroke compressed, operations for forming can be carried out to workpiece accurately when object is punch forming.
Operation principle of the present invention is: during work, is first placed on punch by workpiece, positions with the square hole on punch; During punching press, punch is pressed into by die, and coordinates die mould by workpiece punch forming by punch and die; After punch forming, workpiece is ejected in die by knockout rod.
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.
