Abstract

The invention discloses a supporting hinged shaft forging technology. The supporting hinged shaft forging technology includes following steps: (1) chamfering one end of a steel ingot blank, pressing a dead head at the other end of the steel ingot blank so as to form a pincer handle, cutting an unnecessary segment of the steel ingot blank, cutting a water gap, and removing burrs; (2) placing the steel ingot blank into a hole disk, and performing upsetting on the steel ingot blank; (3) fetching out the steel ingot blank, chamfering four edges of the steel ingot blank, rounding the steel ingot blank from all directions, and filing the pincer handle; (4) drawing the steel ingot blank into a pole, forging the pole until steps at two ends of the pole are forged to the designed dimension, and then placing the two ends of the pole into a die, and performing upsetting on the pole; (5) smoothing the two ends of the pole, repeatedly shrinking the pole in all the directions, and using a punch to push double sides of the pole; (6) using a martensite rod to perform chambering twice; (7) smoothing two end faces of the pole, enabling the thickness of the two end faces of the pole to reach the designed size, and inserting the punch into a round inner hole so as to smooth the round inner hole; (8) performing heat treatment after the size of the pole is qualified through measurement. The supporting hinged shaft forging technology has the advantages of being simple and convenient, can be used to directly obtain a qualified product through a forging method, prevents lathing from damaging tissue fibers of the product, prolongs use life of the product, and simultaneously reduces a processing volume, saves materials, and reduces cost.

Description

A kind of supporting hinge Forging Technology

Technical field

The present invention relates to a kind of Forging Technology, particularly a kind of supporting hinge Forging Technology.

Background technology

Existing supporting hinge Forging Technology, its key step is: the forging first woollen being forged into class shape from all directions, then puts into that lathe carries out machining to installing positions of bearings is shaping.Do although it is so and can form product, but there is following deficiency in such technique: 1. processing capacity is large, causes process time longer; 2., when carrying out turnery processing on lathe, make waste of material amount large, waste material, improve forging cost; 3. when carrying out turnery processing, destroying the fibr tissue of forging, affecting forging quality, thus cause the service life of product shorter.

Summary of the invention

Object of the present invention is just to provide a kind of supporting hinge Forging Technology that can improve supporting hinge quality.

The object of the invention is to be realized by such technical scheme, a kind of supporting hinge Forging Technology, this technique comprises the steps: that chamfered edge is carried out in steel ingot blank one end by (1), and other end pressure-pad mouth does pincers handle, excision additional length, water dividing gap, deburring; (2) blank is loaded drain cap jumping-up to design size; (3) take out blank and press cubic chamfering, pull out round as a ball to design size from all directions, wrong pincers handle; (4) dead man, forges two ends step to design size, then two ends is loaded mould jumping-up to design size; (5) smooth two ends are to design size, repeatedly receive from all directions, rush two-sided punching perforation with drift; (6) be beneficial to horse rod and carry out twice reaming, to design size; (7) smooth both ends of the surface, make thickness reach design size, then fill with circle endoporus with drift, finally carry out smooth; (8), after red survey size qualification, heat treatment is handed over.

Between described step (3) and step (4), be provided with jumping-up step, by base, jumping-up is to design size, from diameter square pressure four directions.

In order to seam blemish, before step (1), blank need be heated to 1180 DEG C ~ 1220 DEG C.

In order to make blank have plasticity, be convenient to forging, before step (2), need by blank heating to 1230 DEG C ~ 1270 DEG C.

In order to control to stop the temperature of forging, before step (5), need by blank heating to 1200 DEG C ~ 1240 DEG C.

Owing to have employed technique scheme, the present invention has the advantage of following simple process, it is adopted can directly to obtain qualified product by the means of forging, prevent turnery processing to the destruction of product tissue fibers, improve service life, meanwhile, also reduce processing capacity, save material, reduce cost.

Accompanying drawing explanation

Accompanying drawing of the present invention is described as follows:

Fig. 1 is supporting hinge structural representation of the present invention.

Detailed description of the invention

Be described in further detail the specific embodiment of the present invention below in conjunction with accompanying drawing, but the present invention is not limited to these embodiments, any improvement or alternative on the present embodiment essence spirit, still belongs to the claims in the present invention scope required for protection.

Embodiment 1: as shown in Figure 1, a kind of supporting hinge Forging Technology, this technique comprises the steps: that chamfered edge is carried out in steel ingot blank one end by (1), and other end pressure-pad mouth does pincers handle, excision additional length, water dividing gap, deburring; (2) blank is loaded drain cap jumping-up to design size; (3) take out blank and press cubic chamfering, pull out round as a ball to design size from all directions, wrong pincers handle; (4) dead man, forges two ends step to design size, then two ends is loaded mould jumping-up to design size; (5) smooth two ends are to design size, repeatedly receive from all directions, rush two-sided punching perforation with drift; (6) be beneficial to horse rod and carry out twice reaming, to design size; (7) smooth both ends of the surface, make thickness reach design size, then fill with circle endoporus with drift, finally carry out smooth; (8), after red survey size qualification, heat treatment is handed over.

Due in above-mentioned technique, do not adopt turnery processing, the fibr tissue of product can be made to be destroyed, ensure that the quality of product, extend the service life of product.

Further, between described step (3) and step (4), be provided with jumping-up step, by base, jumping-up is to design size, from diameter square pressure four directions.By jumping-up, make from all directions more easy-formation, meanwhile, jumping-up can increase the density of metal, and internal flaw obtains seam, and product quality is better.

Further, before step (1), blank need be heated to 1180 DEG C ~ 1220 DEG C.Steel ingot blank is heated between this temperature, can the defect on seam surface, make the chemical composition of metal evenly.

Further, before step (2), need by blank heating to 1230 DEG C ~ 1270 DEG C.Between blank heating to this temperature, the state that the plasticity of blank can be made to reach best, is convenient to subsequent handling and carries out shaping to it.

Wherein, before step (5), need by blank heating to 1200 DEG C ~ 1240 DEG C.Do like this and can control to stop forging and make temperature, insulating product interior tissue.
