Abstract
The utility model discloses an interior side manages punching die, including upper and lower die holder, upper and lower backing plate, upper and lower template still includes the stripper, and lower stripper, upper and lower stripper are placed in respectively between the upper and lower template, and it sets up the die socket to float between upper and lower stripper, and the die socket is built -in to have the die, and interior fang guanke inserts to the die and makes the die stretch into to interior fangguanli, is provided with the drift in the top and the below of die. The utility model discloses an after the floating concave mold scheme of punching a hole, the punching process quality of interior side pipe improves greatly, uses floating concave mold to prevent effectively also that the drift is impaired, makes the drift life -span prolong.
Description
Technical field
This utility model belongs to auto parts processing mold technical field, more specifically, it relates to punching multiple holes on square tube casement in a kind of.
Background technology
Lifting landing leg generally it is equipped in the outside of semitrailer leading portion left and right side bar, to support the first half section weight of semitrailer, and the height of scalable semitrailer front end, adapt to the into and out of traction seat；When semitrailer is drawn traveling, interior lower limb is retracted, and lifts away from ground, keeps safe distance.Supporting leg includes the parts such as outer lower limb, interior square tube, screw mandrel screw assembly, and wherein, one end of interior square tube needs symmetry punching two circular holes, and at present, interior piercing on rectangular tube frock and technique are all comparatively weak, cause that punching quality is poor.
Utility model content
The purpose of this utility model is in that to provide a kind of interior punching multiple holes on square tube casement, solves the existing ropy technical problem of interior piercing on rectangular tube, to overcome deficiency existing in prior art.
The technical scheme in the invention for solving the technical problem is: interior punching multiple holes on square tube casement, including upper and lower die holder, upper and lower backing plate, upper and lower template, also include loading and unloading material plate, lower stripper, upper and lower stripper is respectively placed between upper and lower template, and floating between upper and lower stripper arranges die socket, and die socket is built-in with die, interior square tube can be inserted to die and make die stretch in interior square tube, is provided with drift over and under at die.
It is provided with guide pin bushing and guide pillar between described upper and lower die holder.
Arranging little guide pin bushing in described die socket, little guide pillar slides in little guide pin bushing, and the top of little guide pillar connects limited block.
Between described lower stripper and die shoe, discharging screw is set.
Between described loading and unloading material plate and upper bolster, discharging screw is set, sheathed brute spring on discharging screw.
The beneficial effects of the utility model are:
After have employed the scheme of floating cavity die punching, the punching operation quality of interior square tube is greatly improved, and uses floating cavity die also effectively to prevent drift impaired, makes the drift life-span be extended.
Accompanying drawing explanation
