Abstract
The invention relates to the technical field of bolt processing technic, in particular to a bolt processing technic featuring one-step molding, which is characterized by comprising the following steps of the processing technic: 1. blanking; 2. primary upsetting; 3.secondary upsetting; 4.tertiary upsetting; 5.final upsetting and molding; the invention has the beneficial effects that in the processing technic, the one-step molding mould can be turned out by extrusion of a 4-location bolt forming machine without any scrap generated; in terms of materials, the materials can be saved by 5% compared with the materials used in the old processing technic with the 4-location bolt forming machine adopted, and no extra processes are needed, thus greatly reducing cost, effectively controlling cost, reducing labor intensity and ensuring reliable product quality.
Description
[technical field]
The present invention relates to a kind of bolt processing technic featuring technical field, especially relate to a kind of one-time formed bolt processing technic featuring.
[background technology]
This time the technology of invention mainly is at bulb flange face bolt.This type of bolt of processing all was to utilize punch ram, trimming for forming in addition after by first cold-heading coning when processing hexagonal flange face in the past.Old technology cold headers have only two pairs of moulds, must just can finish by punch press reprocessing after the moulding, and have waste material to produce.Old technology has not only increased unnecessary operation but also waste raw material (side cut will be excised unnecessary waste material), and quality is also unstable simultaneously.
[summary of the invention]
The objective of the invention is to solve above-mentioned deficiency, a kind of one-time formed bolt processing technic featuring is provided, can one-shot forming, aspect material, to save than old technology materials, there is not other extra unnecessary operation.
The present invention adopts following technical proposals: a kind of one-time formed bolt processing technic featuring is characterized in that: comprise following processing technology step:
1, blank;
2, just upset;
3, two upset;
4, three upset;
5, whole rammer moulding.
At first the biscuit that will draw by cutter is cut into the required length of converted products, again through just upsetting, the material that cuts is grown the end frustum of a cone of upsetting out, for the postorder moulding lays the first stone; Two upset continue to upset close with product coniform, the deflection when reducing moulding; Three upset is by the cold-heading first shape similar with finished product of upsetting out, further reduces deflection, controls the life-span of mould with this.By the special patrix of whole rammer moulding, finish the process of entire product at last.
The mould that is adopted in the described whole pier moulding process comprises upper die and lower die, reaches embossing grooves down towards rod, thimble, alloy protecting layer, last embossing grooves, described indent bottom of going up embossing grooves is a sphere, the indent inwall is a regular hexahedron, and the oral area of indent is provided with one and extends outwardly into chamfering; Described embossing grooves down is the cylinder bodily form.
Beneficial effect of the present invention: technology can be finished by four merit position bolt make-up machine extruding by one-time-shaped mould, do not produce any waste material, on four merit position bolt make-up machines, to save 5% with the material aspect than old technology materials, do not have other extra unnecessary operation, reduce expense so greatly, controlled cost effectively, reduce personnel's labour intensity, guaranteed the reliable quality of product.
[description of drawings]
Fig. 1 is existing bolt processing technic featuring flow chart;
Fig. 2 is a bolt processing technic featuring flow chart of the present invention;
Fig. 3 is the structural representation of the mould that adopted in the whole pier moulding process of the present invention.
Among the figure: 1 is that patrix, 2 for last embossing grooves, 7 is down embossing grooves for alloy protecting layer, 6 for dashing rod, 4 for thimble, 5 for counterdie, 3.
[specific embodiment]
Below in conjunction with the drawings and specific embodiments the present invention is described in detail:
As shown in the figure, a kind of one-time formed bolt processing technic featuring is characterized in that: comprise following processing technology step:
1, blank;
2, just upset;
3, two upset;
4, three upset;
5, whole pier moulding.
The mould that is adopted in the described whole pier moulding process comprises upper die and lower die, reaches embossing grooves down towards rod, thimble, alloy protecting layer, last embossing grooves, described indent bottom of going up embossing grooves is a sphere, the indent inwall is a regular hexahedron, and the oral area of indent is provided with one and extends outwardly into chamfering; Described embossing grooves down is the cylinder bodily form.
Claims (2)
1, a kind of one-time formed bolt processing technic featuring is characterized in that: comprise following processing technology step:
1, blank;
2, just upset;
3, two upset;
4, three upset;
5, whole pier moulding.
2, one-time formed bolt processing technic featuring as claimed in claim 1, it is characterized in that: the mould that is adopted in the described whole pier moulding process comprises upper die and lower die, reaches embossing grooves down towards rod, thimble, alloy protecting layer, last embossing grooves, described indent bottom of going up embossing grooves is a sphere, the indent inwall is a regular hexahedron, and the oral area of indent is provided with one and extends outwardly into chamfering; Described embossing grooves down is the cylinder bodily form.
