Abstract
The utility model discloses a support base axle punching die, including upper and lower die holder, upper and lower backing plate still includes matrix plate, and punch plate, stripper, stripper arrange in between matrix plate and the punch plate, and matrix plate floats and sets up in the lower bolster top, and matrix plate is built -in to have the die, and the die stretches into to the hole of support base axle, is equipped with the drift in the top of die. The utility model discloses an after the floating concave mold scheme of punching a hole, the punching process quality of support base axle 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 a kind of support plinth axle perforating die.
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, support plinth axle, and wherein, one end of support plinth axle needs to rush circular hole, and at present, support plinth axle punching tool 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 support plinth axle perforating die, solves the technical problem of existing support plinth axle punching quality difference, to overcome deficiency existing in prior art.
The technical scheme in the invention for solving the technical problem is: support plinth axle perforating die, including upper and lower die holder, upper and lower backing plate, also includes die block, punch retainer, stripper, stripper is placed between die block and punch retainer, and die block floats and is arranged on above lower bolster, and die block is built-in with die, die stretches to the endoporus of support plinth axle, is arranged over drift at die.
It is provided with guide pin bushing and guide pillar between described upper and lower die holder.
Packing ring and screw are set in the side of die block.
Discharging screw is set between described stripper and upper bolster.
Support spring is set between described die shoe and die block.
Little guide pin bushing and little guide pillar are set between described stripper and lower bolster.
The beneficial effects of the utility model are:
After have employed the scheme of floating cavity die punching, the punching operation quality of support plinth axle is greatly improved, and uses floating cavity die also effectively to prevent drift impaired, makes the drift life-span be extended.
