Abstract
The present invention discloses one double control liquid metal pressure casting and forging method. In one integral casting and forging machine, pressure casting and press forging are completed. After liquid metal of smelting temperature 500-800 deg.c is filled into mold cavity in 8-40 MPa pressure and 0.01-10 m/s speed, press forging is performed in 0.05-2 sec in the forging mold temperature 200-350 deg.c and pressure 6-30 MPa. The present invention completes the continuous pressure casting and die forging in the same production period, and the produced part has 10 % over reduced shrinkage cavity and 10 % over raised strength compared with corresponding pressure cast part. The present invention is especially suitable for producing precise mechanical parts with complicated shape and high strength requirement and has stable and high quality.
Description
Technical field
The present invention relates to the method for die cast metal moulding, the one-time formed method of two controls is forged in particularly a kind of metal liquid die casting.
Background technology
The method of traditional compression casting is that liquid metal is in high pressure, the casting of high speed retrofilling mold cavity, often the gas in the die cavity is difficult to get rid of clean and turbulent flow and causes the yield rate of foundry goods internal porosity, shrinkage cavity and loose generation, particularly die casting are complex-shaped, requirement of strength is high Precision Machinery Elements such as auto parts machinery lower.
Summary of the invention
The objective of the invention is at above-mentioned shortcoming, work out a kind of metal liquid die casting and forge the one-time formed method of two controls, can in the same production cycle, carry out compression casting and die forging continuously by the liquid towards metal, the special adaptation, made the Precision Machinery Elements complex-shaped, that requirement of strength is high, steady quality, the yield rate height.
The object of the present invention is achieved like this:
Adopt liquid casting to forge two control one-shot forming casting forging machines, its basic principle is an additional function of forging on the basis of pressure casting machine, and its structure is that two big stroke oil cylinders are finished matched moulds and Qi Mo action; A little stroke large tank is finished liquid state or semisolid die forging; Carry the blank oil cylinder: liquid metal is inputed to the filling die cavity; The side cylinder---the syntype pressurization is used.
Adopt that the structure of pressurization forging mold comprises with the similar upper and lower mould of die casting, framed, core rod, slidingly determines, outside runner and the ejecting mechanism, also comprise the drift that can forge.The gap length that wherein forges and presses drift and mould is very important, and too small meeting causes drift and mould to collide or block, and crosses conference and causes and fly material.
It is to adopt pressure the defeated die cavity of liquid metal that the one-time formed technological process of two controls is forged in metal liquid die casting, and two control one-shot formings are forged in compression casting, pressurization, eject one-shot forming part in the die cavity.
It is as follows that the one-time formed technological parameter of two controls is forged in metal liquid die casting:
1, liquid metal input cavity pressure casting
Control melt temperature is 500-800 ℃, and the pressure that liquid metal is inputed to the filling die cavity is the 8-40 MPa, and filling speed is the 0.01-10 meter per second, the liquid metal pressure casting.Whether above pressure casting process parameter control will directly influence molten metal liquid can fill up the entire die die cavity, and what of pore in the molten metal.
2, pressurization is forged
(1), the temperature of pressurization forging mold:
The temperature of control pressurization forging mold is 200-350 ℃, and mold temperature directly influences the quality and the die life of part, and this mold heated adopts the mode of deep fat heating.
(2), the time of beginning is forged in pressurization:
The time of control pressurization forging beginning is the 0.05-2 second after molten metal liquid fills up the entire die mold cavity forming, and there is very big influence the time that beginning is forged in pressurization to the forging effect that pressurizes.
(3), the pressure of pressurization forging:
The control forging pressure is the 6-30 MPa, and the forging pressure size is to the physical and mechanical properties of part, and institutional framework has direct influence.
3, eject part
The breakdown mould ejects die cavity to the part after forging.
Owing to adopt the present invention, the liquid towards metal carries out compression casting and die forging continuously in the same production cycle, the density of part reduces more than 10% than the shrinkage cavity quantity of die casting, the intensity degree of part promotes more than 10% than die casting, the special adaptation, produced the Precision Machinery Elements complex-shaped, that requirement of strength is high, steady quality, the yield rate height.
Embodiment
In conjunction with the embodiments, further describe method of the present invention.
Embodiment: metal liquid die casting is forged two control one-shot formings and is made the motorcycle engine shell
Adopt liquid casting to forge two control one-shot forming casting forging machines, its basic principle is an additional function of forging on the basis of pressure casting machine, and its structure is that two big stroke oil cylinders are finished matched moulds and Qi Mo action; A little stroke large tank is finished liquid state or semisolid die forging; Carry the blank oil cylinder: liquid metal is inputed to the filling die cavity; The side cylinder---the syntype pressurization is used.
Adopt that the structure of pressurization forging mold comprises with the similar upper and lower mould of die casting, framed, core rod, slidingly determines, outside runner and the ejecting mechanism, also comprise the drift that can forge.The gap length that wherein forges and presses drift and mould is very important, and too small meeting causes drift and mould to collide or block, and crosses conference and causes and fly material.

(2), the time of beginning is forged in pressurization:
The time of control pressurization forging beginning is 0.05 second after molten metal liquid fills up the entire die mold cavity forming.
(3), the pressure of pressurization forging:
The control forging pressure is 10 MPas.
3, eject part
