Abstract
The invention discloses a combined die for forming a cylindrical head shaft shoulder screw, which comprises a sleeve. An inner hole is arranged in the sleeve, a die sheet, a front die core and a rear die core which are closely connected are sequentially arranged in the inner hole of the sleeve, the rear die core is connected onto the sleeve through a lock sleeve, a head cavity is arranged in the die sheet, a rod cavity is arranged in the front die core, a thread cavity is arranged in the rear die core, and the head cavity, the rod cavity and the thread cavity are communicated with one another. After the die is abraded during use, only an abraded component can be taken out and replaced, and the whole sleeve does not need to be replaced, so that maintenance is more convenient, and maintenance cost is reduced. Inner layers of the die sheet, the front die core and the rear die core are made of excellent tungsten alloy materials, other portions are made of common steel, high-quality materials are saved to a certain degree, manufacturing cost is reduced, the abrasion resistance of the combined die is enhanced, and the service life of the combined die is prolonged.
Description
Technical field
The present invention relates to a kind of mould, relate in particular to a kind of socket cap shaft shoulder screw moulding assembling die that is used for.
Background technology
Interior hexagonal socket cap shaft shoulder screw comprises cylindrical head, bar portion and threaded joints, produce this socket cap shaft shoulder screw in the prior art mainly through forging or through die production, but the socket cap shaft shoulder screw of producing is relatively poor aspect quality such as precision, durability; Do not reach high-level requirement, common forging method production efficiency is low, can not realize industrialized production; And the method for passing through the upper and lower mould punching press cold-heading of mould in the prior art is processed; Mould repeated multiple times pressurized and being corroded for a long time in the production process, itself precision change, and have directly caused the low precision of product; Influence product quality; This structural repair is safeguarded very trouble, and upper and lower mould replacement cost is higher, the replacement poor-performing.
Summary of the invention
Technical problem to above-mentioned existence the objective of the invention is: proposed a kind of socket cap shaft shoulder screw moulding assembling die, to solve the maintenance maintenance trouble, it is high to change upper and lower mould cost, the technical problem of replacement poor performance.
Technical solution of the present invention is achieved in that a kind of socket cap shaft shoulder screw moulding assembling die, comprises body, has endoporus in the said body, is provided with matrix, preceding die, back die in the said body endoporus successively; Said matrix and preceding die, preceding die with the back die between for closely to be connected; Said back die is connected on the body through lock tube; Be provided with head shape chamber in the said matrix; Be provided with bar portion shape chamber in the die before said; Be provided with shape chamber, threaded portion in the die of said back; Said head shape chamber, bar portion shape chamber, shape chamber, threaded portion communicate.
Preferably, be respectively equipped with wearing layer on said matrix, preceding die and the back die shape cavity wall; Said wearing layer material adopts tungsten alloy material to process.
Preferably, said lock tube and body are through being threaded.
Because the utilization of technique scheme, the present invention compared with prior art has advantage:
A kind of socket cap shaft shoulder screw moulding assembling die of the present invention through knockdown structural design in the body, has increased the convertibility of mould, has reduced faster cost; After wearing and tearing in the mould use, occurring, can be only the parts of wearing and tearing be taken out, need not change whole body, make like this maintenance, safeguard conveniently, reduce the cost that keeps in repair.Adopt good tungsten alloy material to process through internal layer simultaneously at matrix, preceding die, back die; Other parts adopt general steel to process; Saved the material of high-quality to a certain extent; Not only reduce manufacturing cost, but also increased the antiwear characteristic of product, and prolonged the service life of these parts.
Description of drawings
Below in conjunction with accompanying drawing technical scheme of the present invention is described further:
Accompanying drawing 1 is the structural representation of a kind of socket cap shaft shoulder screw moulding assembling die of the present invention;
Wherein: 1, body; 2, matrix; 3, preceding die; 4, back die; 5, head shape chamber; 6, bar portion shape chamber; 7, threaded portion shape chamber; 8, lock tube.
The specific embodiment
Below in conjunction with accompanying drawing the present invention is described.
Accompanying drawing 1 is a kind of socket cap shaft shoulder screw moulding assembling die of the present invention, comprises body 1, has endoporus in the said body 1, is provided with matrix 2, preceding die 3, back die 4 in the endoporus of said body 1 successively; Said matrix 2 and preceding die 3, preceding die 3 with afterwards between the die 4 for closely to be connected; Said back die 4 is threaded on the body 1 through lock tube 8, thereby matrix 2, preceding die 3 and back die 4 are locked in the body 1; Be provided with head shape chamber 5 in the said matrix 2; Head shape chamber 5 is cylindrical; Be provided with bar portion shape chamber 6 in the die 3 before said; Be provided with shape chamber, threaded portion 7 in the die 4 of said back; Said head shape chamber 5, bar portion shape chamber 6, shape chamber, threaded portion 7 communicate; Be respectively equipped with the wearing layer of processing by tungsten alloy material on the shape cavity wall in said matrix 2, preceding die 3 and the back die 4; Said wearing layer material can tungsten alloy material be processed or other antifriction layer materials are processed.
The foregoing description only is explanation technical conceive of the present invention and characteristics; Its purpose is to let the personage that is familiar with this technology can understand content of the present invention and implements; Can not limit protection scope of the present invention with this; All equivalences that spirit is done according to the present invention change or modify, and all should be encompassed in protection scope of the present invention.
