Abstract

The invention discloses a kind of plastic molding method, a kind of metal alloy thixotroping plastic forming method is in particular disclosed.The metal alloy thixotroping plastic forming method, it is characterised in that:Comprise the following steps:Metal alloy is carried out into Isothermal treatment, obtain the semi-solid blank for 80%-95% with fraction solid, and be processed into same mold cavity there is the blank of same volume, then after mould is preheated to 180-250 degrees Celsius, stone mill is sprayed in die cavity so as to the demoulding, above-mentioned semi-solid blank is put into preheated mould after inside holding 10-15 minutes at 530-500 degrees Celsius, thixotroping plastic forming is carried out in mould forging hydraulic machine.The beneficial effects of the invention are as follows:Expand the scope of complicated profiled member, be capable of achieving newly net forming, substantially reduce process procedure, processing cost is low, forging power consumption is low, and cutting output is few, and stock utilization is high, is a kind of method that ideal semi-solid forming technology prepares magnesium alloy materials part.

Description

A kind of metal alloy thixotroping plastic forming method
Technical field
The present invention relates to a kind of plastic molding method, more particularly to a kind of metal alloy thixotroping plastic forming method.
Background technology
Semifixed forming technique is the forming technique for Quanxing grown up after liquid condition shaping technology and formed solid technology, compared with the forming technique that first two is commonly used, itself main difference is that the prefabricated semi solid slurry with non-dendritic structure is injected into mould, coagulation forming under pressure.The advantage of this shaping is product dense structure, and the defect such as casting or forging is few, and comprehensive mechanical property is substantially improved.
The content of the invention
The present invention proposes a kind of metal alloy thixotroping plastic forming method, the metal alloy thixotroping plastic forming method is in view of the shortcomings of the prior art, there is provided a kind of scope for expanding complicated profiled member, newly net forming is capable of achieving, process procedure is substantially reduced, processing cost is low, forging power consumption is low, cutting output is few, and stock utilization is high, is a kind of method that ideal semi-solid forming technology prepares magnesium alloy materials part.
The technical scheme that present invention solution above-mentioned technical problem is used is described below:
A kind of metal alloy thixotroping plastic forming method, it is characterised in that:Comprise the following steps:
Metal alloy is carried out into Isothermal treatment, obtain the semi-solid blank for 80%-95% with fraction solid, and be processed into same mold cavity there is the blank of same volume, then after mould is preheated to 180-250 degrees Celsius, stone mill is sprayed in die cavity so as to the demoulding, above-mentioned semi-solid blank is put into preheated mould after inside holding 10-15 minutes at 530-500 degrees Celsius, thixotroping plastic forming is carried out in mould forging hydraulic machine.
The beneficial effects of the invention are as follows:Expand the scope of complicated profiled member, be capable of achieving newly net forming, substantially reduce process procedure, processing cost is low, forging power consumption is low, and cutting output is few, and stock utilization is high, is a kind of method that ideal semi-solid forming technology prepares magnesium alloy materials part.
Specific embodiment
The present invention is in view of the shortcomings of the prior art, propose a kind of metal alloy thixotroping plastic forming method, the technical scheme that solution above-mentioned technical problem is used is described below:
A kind of metal alloy thixotroping plastic forming method, it is characterised in that:Comprise the following steps:
Metal alloy is carried out into Isothermal treatment, obtain the semi-solid blank for 80%-95% with fraction solid, and be processed into same mold cavity there is the blank of same volume, then after mould is preheated to 180-250 degrees Celsius, stone mill is sprayed in die cavity so as to the demoulding, above-mentioned semi-solid blank is put into preheated mould after inside holding 10-15 minutes at 530-500 degrees Celsius, thixotroping plastic forming is carried out in mould forging hydraulic machine.
The beneficial effects of the invention are as follows:Expand the scope of complicated profiled member, be capable of achieving newly net forming, substantially reduce process procedure, processing cost is low, forging power consumption is low, and cutting output is few, and stock utilization is high, is a kind of method that ideal semi-solid forming technology prepares magnesium alloy materials part.
It should be noted that above-mentioned specific embodiment is exemplary, under above-mentioned teaching of the invention, those skilled in the art can carry out various improvement and deformation on the basis of above-described embodiment, and these are improved or deformation is within the scope of the present invention.
It will be understood by those skilled in the art that specific descriptions above are intended merely to explain the purpose of the present invention, the present invention is not intended to limit.Protection scope of the present invention is limited by claim and its equivalent.
