Abstract

The invention discloses a method for adjusting gaps after quenching of die forging inserts. The method comprises the following steps of: 1) machining a first insert (1) and a second insert (2) into hexahedrons, the top and the bottom of which are of parallelograms or trapezoids, so that the abutted surfaces of the two inserts are oblique vertical surfaces (3); 2) after bench work assembly and numerical control machining, performing integral quenching heat treatment on the first insert (1) and the second insert (2); 3) adjusting a fixing screw (4) to loose; and 4) adjusting the position of the first insert (1) or the second insert (2) in the front and back direction, so that the first insert (1) and the second insert (2) can tightly jointed. By the method, the bench work time can be reduced, the bench work quantity is reduced, the development period of a die is reduced, the qualities of the die and a product are improved at the same time, the service life of the die is longer, and the quality of the product is higher.

Description

A kind of mould forges the method that the quenching post gap of inserting is adjusted
Technical field
The invention belongs to mould manufacturing field, the mould that relates in this field forges the assembly technology of inserting.More particularly, the present invention relates to mould and forge the method that the quenching post gap of inserting is adjusted.
Background technology
Now, China greatly develops automobile industry, and mold manufacturing industry is also driven, and development is swift and violent.Specification requirement is higher in diel is made, difficulty of processing is bigger with cold punching die for body of a motor car.The quality of body of a motor car part quality directly depends on the manufacture level of this component die.
At present, use in the automobile cold-punching mold through the heat treated place of inserting that forges also to get more and more, it is more and more important that the processing and assembling of inserting also seems.Insert after quenching, the certain deformation amount is arranged, make can to produce minim gap between inserting and inserting, this is unfavorable for the splicing of inserting perhaps can not guaranteeing two Pingdus of inserting the seam crossing working face in Mold Making.How eliminating the gap, improve the quality of mould and product, is the problem that we need solve.
Summary of the invention
The invention provides the method for quenching post gap and Pingdu between a kind of simple adjustment die insert, its objective is in order to reduce the bench work time, reduce the bench work amount, be convenient to the pincers worker assembling, mold developing cycle is reduced, improve mould and product quality simultaneously, make die life longer, make product quality higher.
The present invention specifically discloses a kind of mould and has forged the method that the quenching post gap of inserting is adjusted, and comprises the steps:
1) insert first and second insert that to be processed into bottom surface be parallelogram or trapezoidal hexahedron, making two binding faces of inserting is oblique facade;
2) after, the digital control processing upright through the pincers worker group, insert and second insert and carry out integral quenching heat treatment first;
3) regulate hold-down screw, make it lax;
4) regulate first along fore-and-aft direction and insert or second position of inserting, make first to insert and second insert and to fit tightly.
5) use pin (5) insert (1) first and second insert (2) fix.
This method can be used for the adjustment of inserting more than two.
Description of drawings
Fig. 1: the present invention adjusts schematic diagram at the gap of inserting.
Description of reference numerals:
1, first inserts; 2, second insert; 3, oblique facade; 4, screw; 5, pin; 6, working face.
The specific embodiment
Below in conjunction with accompanying drawing invention is specifically described.
Insert first and 1 and second to insert 2 to be processed into bottom surface be parallelogram or trapezoidal hexahedron, other four facades are respectively perpendicular to two bottom surfaces, because the bottom surface is parallelogram or trapezoidal, to have a side elevation at least be along X axis with respect to working face 6(thereby each is inserted) oblique facade 3, the binding face between this oblique facade is inserted as two.After, the digital control processing upright through the pincers worker group, carry out integral quenching heat treatment.After the heat treatment, insert and 1,2 slight deformation, contraction can take place, two insert between splicing the gap can appear.In order to dwindle this gap, the principle of utilizing the inclined-plane to cooperate under hold-down screw 4 relaxed states, is regulated arbitrary position of inserting along Y-direction (being fore-and-aft direction), make two to insert and 1,2 can fit tightly, adjust first 1 and second purpose of inserting gap between 2 liang of oblique facades 3 of inserting thereby reach.Simultaneously, also can reach the purpose of adjusting working face 6 Pingdus of inserting.
After having adjusted, re-use pin 5 and two are inserted 1,2 fixing.The method can be used for blanking die, drawing die, trimming die, flange die, sizing die of cold-punching mould etc.
The above, obvious exclusive list not.Therefore, specific implementation of the present invention is not subjected to the restriction of aforesaid way.As long as adopted the change of the various unsubstantialities that method of the present invention design and technical scheme carry out, or without improvement inventive concept of the present invention and technical scheme are directly applied to other occasion, all within protection scope of the present invention.

Claims (3)

1. a mould forges the method that the quenching post gap of inserting is adjusted, and it is characterized in that comprising the steps:
1) insert (1) first and second insert that (2) to be processed into bottom surface be parallelogram or trapezoidal hexahedron, making two binding faces of inserting is oblique facade (3); Other four facades are respectively perpendicular to two bottom surfaces, because the bottom surface is parallelogram or trapezoidal, to have a side elevation at least be oblique facade (3) with respect to working face (6) thereby each is inserted, the binding face between this oblique facade is inserted as two;
2) after, the digital control processing upright through the pincers worker group, to first insert (1) and second insert (2) carry out integral quenching heat treatment;
3) regulate hold-down screw (4), make it lax;
4) regulate first along fore-and-aft direction and insert (1) or second position of inserting (2), make first insert (1) and second insert (2) can fit tightly.
2. a kind of mould according to claim 1 forges the method that the quenching post gap of inserting is adjusted, and it is characterized in that, also comprises:
5) use pin (5) insert (1) first and second insert (2) fix.
