Abstract

The utility model relates to the field of bolt processing equipment, in particular to a die for processing a one-step forming bolt, which comprises a first upsetting process die, a second upsetting process die and a third process die. The die is characterized in that the die further comprises a final upsetting process die comprising an upper mould, a lower mould, a punch rod, an ejector pin, an alloy protective layer, an upper mould pressure slot and a lower mould pressure slot, wherein the bottom part of the pressure slot of the upper mould pressure slot adopts a spherical surface, the inner wall of the pressure slot adopts a regular hexahedron, and an arc chamfer angle extending outwards is arranged at the mouth part of the pressure slot; and the lower mould pressure slot takes the shape of a cylinder. The utility model has the benefits as follows: the process can be completed through the extrusion of a four-position bolt forming machine by the one-step forming die without producing any waste materials, the four-position bolt forming machine consumes 5 percent less materials as compared with that required in the traditional process, and no extra procedures are required, thereby greatly reducing the expenses, effectively controlling the cost, alleviating the labor intensity of the personnel, and ensuring the reliable quality of the products.

Description

The mould of processing one-shot forming bolt

[technical field]

The utility model relates to a kind of bolt technical field of processing equipment, especially relates to a kind of mould of processing the one-shot forming bolt.

[background technology]

At present, the mould that adopted when processing hexagonal flange face of this type of bolt of processing bulb flange face all is to utilize processing steps such as punch ram, trimming for forming in addition after by first cold-heading coning.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 purpose of this utility model is to solve above-mentioned deficiency, and a kind of mould of processing the one-shot forming bolt is provided, can one-shot forming, aspect material, to save than old technology materials, and there is not other extra unnecessary operation.

The utility model adopts following technical proposals: a kind of mould of processing the one-shot forming bolt, comprise the mould of first rammer technology, the mould of two rammer technologies, the mould of three rammer technologies, it is characterized in that: the mould that also comprises whole rammer moulding process, the mould of whole rammer moulding process comprises upper die and lower die, dashes rod, thimble, alloy protecting layer, go up embossing grooves and under 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 an outward extending circular arc chamfering; Described embossing grooves down is the cylinder bodily form.

The utility model beneficial effect: 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, not have other extra unnecessary operation, reduce expense so greatly, controlled cost effectively, reduced personnel's labour intensity, guaranteed the reliable quality of product, be worthy of popularization.

[description of drawings]

Fig. 1 is the structural representation of one-shot forming bolt processing mold of the present utility model.

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 utility model is described in detail:

As shown in the figure, a kind of mould of processing the one-shot forming bolt, comprise the mould of first rammer technology, the mould of two rammer technologies, the mould of three pier technologies, it is characterized in that: the mould that also comprises whole pier moulding process, the mould of whole pier moulding process comprises upper die and lower die, dashes rod, thimble, alloy protecting layer, go up embossing grooves and under embossing grooves, described indent bottom of going up embossing grooves is a sphere, and the indent inwall is a regular hexahedron, and the oral area of indent is provided with an outward extending circular arc chamfering; Described embossing grooves down is the cylinder bodily form.

Claims

1. mould of processing the one-shot forming bolt, comprise the mould of first rammer technology, the mould of two rammer technologies, the mould of three rammer technologies, it is characterized in that: the mould that also comprises whole rammer moulding process, the mould of whole rammer moulding process comprises upper die and lower die, dashes rod, thimble, alloy protecting layer, go up embossing grooves and under 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 an outward extending circular arc chamfering; Described embossing grooves down is the cylinder bodily form.
