Abstract
The invention discloses a liquid black metal casting and forging molding process, which is characterized by metal liquid casting and forging double-control once molding. In the process, a liquid metal is continuously cast and forged in the same production cycle to obtain a cast and forged part, and compared with a casting, the cast and forged part has shrinkage cavities reduced by over 90 percent, strength strengthened by over 90 percent, material utilization rate increased by 25 to 40 percent, stable quality and high yield.
Description
Technical field
The present invention relates to ferrous metal casting and forging molding technology, the liquid casting and forging molding technology of particularly a kind of ferrous metal.
Background technology
The method of traditional casting be liquid metal at natural gravity effect retrofilling mold cavity, often the gas in the die cavity is difficult to get rid of clean and turbulent flow causes internal porosity, shrinkage porosite and loose generation; In order to solve the loose defective of casting, the employing of casting forging technology efficiently solves this problem, only is applied in the lower non-ferrous metal of fusing point yet cast the forging technology now, and that is that all right is ripe for the cast forging process of ferrous metal, has very big defective.
Summary of the invention
The objective of the invention is to remedy the shortcoming of above-mentioned prior art, the liquid casting and forging molding technology of a kind of ferrous metal has been proposed, this kind process can be cast and die forging by the liquid towards ferrous metal in the same production cycle continuously, the special adaptation, made some workpiece that must forge, and has to implement simply, produce the high characteristics of part mechanical performance.
Technical scheme of the present invention is achieved in that
Adopt liquid casting to forge two control one-shot forming casting forging machines, its operation principle is an additional function of forging on the basis of casting machine, and its structure is that two little stroke oil cylinders are finished matched moulds and molding action, and a big stroke large tank is finished liquid state or semisolid die forging; The side cylinder is used for the syntype pressurization.Adopt the structure of forging mold to comprise and ejecting mechanism is outer, also comprise the drift that can forge with the similar upper and lower mould of die casting, framed, core rod, slide block, runner, the gap length that wherein forges and presses drift and mould is very important, too small meeting causes drift and mould to collide or block, and crosses conference and causes expense to expect.
Implement the liquid casting and forging molding technology of a kind of ferrous metal of the present invention, it is characterized in that: metal liquid casting, the two control of forging one-shot formings.
It is as follows that the one-time formed technological parameter of two controls is forged in metal liquid die casting:
A, the compression casting of liquid metal loading mould cavity
Controlling molten material temperature is 1400 ℃-1500 ℃, liquid metal is inputed to the filling die cavity naturally, until filling up the entire die mold cavity forming.
B, forging
The temperature of control forging mold is 500 ℃-600 ℃.
The time of control forging beginning is the 0.5-2 second after molten metal liquid fills up the entire die mold cavity forming.
The control forging pressure is the 6-100 MPa.
C, eject part
The breakdown mould ejects die cavity to the part after forging.
Owing to adopt the present invention, in the same production cycle, liquid metals is cast continuously and forged and pressed, the shrinkage cavity of the ratio foundry goods of the forge piece of producing has reduced more than 90%, the strength ratio foundry goods promotes more than 90%, stock utilization improves 25%-40%, and steady quality, the yield rate height, and can produce the production efficiency height continuously.
The specific embodiment
Below in conjunction with specific embodiment embodiments of the present invention are provided detailed description.
