Matter carries out horizontal trace regulation, is advantageous to the punching press resilience to blank and makes compensation, decreasing rebound, punching precision is improved.
Further, lateral adjustments component includes laterally driven bar, and one end of laterally driven bar passes through in block, laterally driven
The other end of lever is provided with and cut somebody's hair, and cuts somebody's hair and buffer spring is arranged between block.
Further, the upper mould includes upper die shank, upper padding plate and punch retainer, and upper padding plate and punch retainer are located at
The lower end of cope plate, the lower end of upper die shank are fixedly connected through cope plate with upper padding plate, and the upper end intercalation of punch-pin is fixed in punch-pin
In plate, punch retainer upper end is fixed on upper padding plate lower surface, and upper die shank, upper padding plate and punch retainer form the second punching press
Part, carry out second of punching press, control its decrease speed and pressure, be more beneficial for double layer material plate form can blank into
Type, the stress influence between materials at two layers plate is reduced, substantially reduce the resilience error of blank, improve the accuracy of product.
Further, elastic component is provided between punch-pin top and upper padding plate, is formed and buffered using elastic component, reduces rigidity and hits
Caused by hitting, the stress from punch-pin lower end in punching course is neutralized, is deformed after preventing mould long-time use, elastic component of working together
Small stamping press progressive formation be more beneficial for being bonded deformation between materials at two layers.
Further, the punch-pin includes the connecting portion arranged up and down and curved portions, pushing block upper end are provided with pushing block insert, closes
During mould, cavity plate and both sides pushing block are enclosed in the outside of curved portions, and both sides insert is enclosed in the outside of connecting portion.
Further, the inclined-plane reduces between skewback and pushing block with being 10-15 ° with the angular range of vertical direction
Resistance, corresponding speed is improved, closure pressing speed is fast, good forming effect.
The process for stamping of automobile shock absorber knuckle brackets mould, it is characterised in that：Comprise the following steps：
S1. position blank being placed between punch-pin and cavity plate, adjustment two push away it is fast between position, blank can relax with smooth
Exhibition between punch-pin and cavity plate；
S2. moved downward using vertical drive device driving cope plate, voussoir promotes two pieces of pushing blocks in the presence of inclined-plane
To middle relative motion, blank forms extrusion pressing type intracavitary in punch-pin, cavity plate, both sides pushing block and the insert on pushing block and completed
It is molded for the first time；
S3. using vertical drive device extruding die shank, die shank is micro to be moved down, and completes sizing, decreasing rebound.
Further, S2 steps cope plate pushes speed and pushes speed less than S3 step cope plates.
The present invention compared with prior art, has the advantages that, because carrier blank is double layer material structure, therefore
Easily occur phenomena such as delamination dislocation in punching course, need all directions stress equalization during matched moulds, skewback and push away
The structure of block can realize the synchronous synergetic effect of punch-pin and pushing block, the relative horizontal pushing pressure effect of both sides pushing block, reduce base
The stretching and corrugation of material, double layer material plate stickiness is good, product good integrity, and the present invention is simple in construction, it is possible to achieve knuckle
Carrier blank it is one time punching molded, process is simple, and dimensional uniformity is high, and resilience is small, and controllability is good, can pass through program setting
Carry out automatically controlling operation, save manually, participated in punching course without excessively artificial, reduce enterprise's production cost.
