Abstract

A V-shaped member bending die with inclined wedges is composed of the following components: rollers, inclined wedges, a spring, an upper die base, a movable female die and a male die. Under the function of the male die, the product is firstly compressed to a V-shaped member. Along with downward movement of the upper die base, the male die is in place, and the spring is compressed. The inclined wedges which are equipped on the upper die base are pressed to the rollers, thereby causing the movable female die block to move to the central part, and inwards bending two sides of the V-shaped member for forming.

Description

A kind of V-arrangement spare bending die with wedge

Technical field

The present invention relates to the metal stamping mould, is a kind of V-arrangement spare bending die with wedge.

Background technology

At present, known cold stamping is to utilize the punch die that is installed on the forcing press that material is exerted pressure, and it is produced separate or plastic deformation; Thereby obtain a kind of processing method of required part, molding procedure is that material produces plastic deformation under the condition of not breaking, thereby obtains the part of definite shape, size and required precision; Dash etc. like bending, pull and stretch, bulging, flange, reducing, cut-out, essence, though they each have different characteristics, crimping is that operation part edge is rolled into the garden shape near sealing; Be used to process similar part; Blanking is material to be surveyed closed outline separates, separated part of getting off is that plate shaped part becomes the operation part mostly, and punching be with waste material along closed outline from material or the operation part separate, thereby on material or operation part the hole of acquisitions needs; Though above-mentioned stamping die can be accomplished operation separately separately; But along with upgrading product is regenerated, a lot of novel products lean on above-mentioned mold mechanism, can not accomplish at all.Therefore, according to the defective of above-mentioned mould, the spy provides following a kind of mold mechanism, realizes that above-mentioned mold mechanism can not reach some requirement of products.

Summary of the invention

The present invention provides a kind of V-arrangement spare bending die with wedge; It is that workpiece is at first pressed down forming V-shape in the effect of punch; Put in place along with upper bolster continues descending punch, spring is compressed, and two wedges that are loaded on the upper bolster are pressed to roller; The movable matrix piece is moved, with the inside press shaping die of V-arrangement spare dual-side respectively to the centre.When the patrix return, spring resets movable matrix, and part takes out from the punch side direction.This mold mechanism has solved original stamping die can not take out part automatically, has solved the difficult problem of product distortion, and its action is solid and reliable; The pressure transmission is good, can be fit to multiple stamping parts, simultaneously; Mould structure is simple, has saved die cost, and a kind of V-arrangement spare bending mould characteristic with wedge is: roller (1) is installed on the movable matrix (6); And become to be slidingly matched with wedge (2); Spring (3) is communicated with screw and is installed on the upper bolster (4), and upper bolster (4) is fastenedly connected with wedge (2), and punch (8) is connected on the die shank and becomes flexible connection with screw on the spring (3).

Description of drawings

Below in conjunction with accompanying drawing the utility model is further specified.

Fig. 1 is the sectional side elevation of wedge V-arrangement spare bending die.

The specific embodiment:

It shown in the figure a kind of V-arrangement spare bending die with wedge; It is that workpiece at first presses down forming V-shape in the effect of punch (8); Put in place along with upper bolster (4) continues descending punch, spring (3) is compressed, and two wedges (2) that are loaded on the upper bolster (4) are pressed to roller (1); Movable matrix piece (5), (6) are moved to the centre respectively, V-arrangement spare dual-side inwardly is pressed into bending.When the patrix backhaul, spring (7) resets movable matrix, and part takes out from the punch side direction.

Claims

1. the V-arrangement spare bending mould characteristic with wedge is: roller (1) is installed on the movable matrix (6); And become to be slidingly matched with wedge (2); Spring (3) is communicated with screw and is installed on the upper bolster (4); Upper bolster (4) and wedge (2) are fastenedly connected, and punch (8) is connected on the die shank and becomes flexible connection with screw on the spring (3).
