Description

A kind of valve protection cap bi-directional punching die
Technical field
The utility model relates to a kind of pipe fitting punch die, relates in particular to a kind of valve protection cap bi-directional punching die.
Background technology
In pipe fitting process, for the punching die that only has a punch, a punching press can only hole of moulding, sometimes need two symmetrical holes of pipe fitting sidewall upper punch, just need first in hole of a side blow, then pipe fitting Rotate 180 degree is rushed to another hole again, very inconvenient like this, productivity ratio is low.Because be not a stamping-out moulding, second hole of product punching needs rotational workpieces, when pipe fitting rotation, will produce error, causes the shape position error to perforation, can not ensure that two holes are on same axis, and exceeding allowable tolerance will often cause workpiece to scrap.On the other hand, in the monolateral workpiece even fracture that can deform stressed in the situation that.
Publication number is that the Chinese patent literature of CN201960043U discloses a kind of Novel cantilever type bidirectional punching die, relate to a kind of diel, comprise upper bolster, die shoe, die shank, upper male mould, guide pin bushing and guide pillar, on upper male mould, be provided with stripper, on stripper, be provided with discharging spring, upper male mould is socketed with blank holder outward, position corresponding with upper male mould on die shoe is provided with lower punch, between upper male mould and lower punch, be provided with movable matrix, on die shoe, be vertically installed with little guide pillar, movable matrix is socketed on little guide pillar by little guide pin bushing, movable matrix is vertical with little guide pillar and can slide up and down along little guide pillar, the two sections sidewall surfaces that little guide pillar and movable matrix are corresponding is respectively arranged with upper limit position block and lower position block, the position that the position that movable matrix upper surface is corresponding with upper male mould and lower surface and lower punch are corresponding has die hole.
Although this Novel cantilever type bidirectional punching die has been realized bidirectional punching simultaneously, because blanking pressure is born by cantilever, the blanking pressure that cantilever bears is larger.Especially the thicker pipe fitting of tube wall produces larger reaction force in the time of punching, acts on cantilever, makes die wear very fast.Shorten die life on the one hand, reduced on the other hand the quality of fit of mould, also just reduced punching precision.

In order to improve punching precision, also in order to ensure that slide block is in motion process, the inclined-plane of slide block all the time with the lead-in chamfered keeping parallelism of carving type piece, preferably, described base is provided with two gathering sills, described two slide blocks are arranged on respectively in corresponding gathering sill.
Described two gathering sills are on same straight line.
As preferably, on each slide block, be fixed with convex mould base, described two punch are separately fixed on corresponding convex mould base.
Change conveniently for described convex mould base, preferably, on each slide block, be equipped with side slot, corresponding convex mould base is fixedly plugged in this side slot.
As preferably, a described convex mould base dorsad side of die socket is provided with anticreep flange, is provided with the stopper slot matching with anticreep flange in the side slot at convex mould base place.
Described punch has with the anticreep flange similar structures of convex mould base and matches with convex mould base.
As preferably, described return springs is polyurethane rubber piece.Avoid the wearing and tearing of metallic elastic part to mould, increased die life.
In order to facilitate the scrap that punching produces to discharge, preferably, the inside of described die socket is provided with each punching and connects the chip-removal hole that hole is communicated with.
Described chip-removal hole vertically connects die socket.
As preferably, the inside of described die socket is also provided with and is communicated with chip-removal hole and each punching connects the transitional pore between hole.
The beneficial effects of the utility model are also: die socket inside is provided with vertical chip-removal hole, and the discharge of the scrap of being more convenient for, enhances productivity.
