Summary of the invention
In view of the problem of known technology existence at present, but the technical problem that the present invention will solve is to be to provide a kind of energy-conservation joint material disposal molding upset ratio greater than 3 forging, the stamp forging mould of long service life.
For solving the problems of the technologies described above, the present invention takes following technical scheme to accomplish:
A kind of stamp forging mould; Comprise upper die and lower die, the drift of patrix and the die orifice of counterdie over against, it is characterized in that: the cylindrical of said drift is provided with movable sheath; Sheath is provided with the sheathed endoporus that exposes the elongated forging of said counterdie die cavity; The endoporus of sheath and the cylindrical of drift are slidingly matched, and sheath is connected on the patrix through elastic device, can develop each other and be adjacent to during the plane contact at the lower surface of sheath and counterdie die orifice place.Said
The mold cavity volume of counterdie is slightly smaller than the volume of forging.
Common forging molding is to accomplish deformation process by the upper die and lower die extrusion billet, and technical scheme of the present invention is: during forging molding, the sheath of patrix down moves with patrix; Sheath at first entangles the bar that is exposed at counterdie die cavity outside, but not extruded bar stock, along with moving down of patrix; Sheath is adjacent to the plane at counterdie die orifice place under the effect of elastic device and stops to move downward; This moment, bar was sealed by sheath endoporus and counterdie die cavity, and patrix continues to move downward, and the drift of patrix is pushing away bar in sheath downward; Till bar was squeezed to the counterdie die orifice, deformation process finished.The above-mentioned forming process that the present invention realizes, bar be in closed state all the time when distortion, thus the moulding upset ratio greater than 3 situation under, bar can not produce bending yet, solved prior art can not the one-shot forming upset ratio greater than 3 technical bottleneck.Simultaneously, the present invention directly obtains forging by cold deformation, saves the energy; Mould of the present invention is according to clean nearly forming technique design, and the mold cavity volume of counterdie is slightly smaller than the volume of forging, so the forging after forging does not produce unnecessary burr and few machining allowance basically, stock utilization reaches 99.5%, saves raw material.Also have, because forming process of the present invention is that jumping-up is full of, so minimum to the wearing and tearing of mould, die life is very long.
In sum, but the energy-conservation joint material of the present invention disposal molding upset ratio compared with prior art, has outstanding substantive distinguishing features and obvious improvement greater than 3 forging, long service life.
