Description
Technical Field
The utility model relates to a punching press frock field specifically is a special limit frock of receiving of processing spring pin.
Background
The press forming apparatus is a method of forming a work having a desired shape and size by applying an external force to a plate, a strip, a pipe, a profile, or the like by a press machine and a die to cause plastic deformation or separation. The stamped blanks are mainly hot and cold rolled steel sheets and strips. In the world, 60-70% of steel materials are plates, and most of the plates are punched to form finished products. Because the elastic pin needs to pre-press the U-shaped workpiece on the surface of the core rod in the machining process, the workpiece is easy to deform due to too large force, and the pre-pressing effect cannot be achieved due to too small force.
SUMMERY OF THE UTILITY MODEL
In order to solve the above problem, the utility model provides a following technical scheme: a special edge folding tool for processing an elastic pin comprises a main shaft and a workbench, wherein the workbench is over against the lower part of the main shaft; the spindle is characterized by further comprising an upper bottom plate and an upper die, wherein the upper bottom plate is fixed with the spindle through a bolt, and the upper die is fixed with the upper bottom plate through a bolt; the lower end of the upper die is provided with an extrusion groove, the extrusion groove is semicircular, and the edge of the extrusion groove is arc-shaped.
Preferably, the extrusion device further comprises a lower bottom plate and a lower die, the lower bottom plate is fixed with the workbench through a bolt, the lower die is fixed with the lower bottom plate through a bolt, a positioning groove is formed in the surface of the lower die, and the positioning groove is an arc-shaped groove opening and corresponds to the extrusion groove in position.
Preferably, two conical protrusions are arranged on the side edge of the positioning groove.
Preferably, the lower end of the upper die is provided with a pair of female taper angles.
Preferably, the upper surface of the lower die is provided with a pair of male taper angles, and the male taper angles are matched with the female taper angles.
Compared with the prior art, the beneficial effects of the utility model are as follows:
the utility model discloses simple structure, with low costs, simple manufacture, easy operation, purpose-built last mould structure can not damage the shape when making the work piece suppression, and the lower mould angle aligns about can guaranteeing to the public female cone angle simultaneously, improves the punching press precision.
