Abstract
The invention relates to a cold processing technological method, in particular to a cold processing technological method for refining metal grains. The method comprises the steps of extruding, forging and drawing in sequence. The method is simple in operation steps and convenient, and a cold processing manner is adopted, so that the method is low in energy consumption and low in cost. The metal grains obtained through the method are fine and small, thus having high intensity and hardness, and good structural superplasticity.
Description
Technical field
The present invention relates to a kind of cold machining process method, especially a kind of cold machining process method of fining metal crystal grain.
Background technology
Many performances and its crystallite dimension of metal material have close inner link, and the intensity hardness as reduced material with crystallite dimension raises.Therefore refiner material crystal grain is a kind of effective way that people improve metal material combination property always.
Summary of the invention
The present invention is intended to solve the problem, and provides a kind of cold machining process method of fining metal crystal grain, and its operating procedure is simple, convenient, and because adopting cold working mode, therefore less energy consumption, cost are low, and its technical scheme adopted is as follows:
A cold machining process method for fining metal crystal grain, its step is followed successively by:
A) extrude: adopt Equal Channel Angular Pressing method, angle of cut Ф=90 ° in mould adopts, external arc angle is the mould of ψ=20 °, and mould channel diameter used is 20mm;
B) forge: concrete steps are:
(1) metal material of extruding is forged on the forging press loaded a die, after forging, place a period of time;
(2) continue more mold exchange, again forge, after forging, place a period of time;
(3) so repeatedly, more mold exchange successively from big to small;
C) drawing: the metal material after forging is placed on the simple and easy drawbench loaded a die and stretches.
Tool of the present invention has the following advantages: operating procedure is simple, convenient, and because adopting cold working mode, therefore less energy consumption, cost are low.The metal grain obtained by the method is tiny, therefore has high intensity and hardness, good tissue hyper-plastic.
Accompanying drawing explanation
Fig. 1: processing process figure of the present invention;
Detailed description of the invention
Below in conjunction with accompanying drawing and example, the invention will be further described:
A cold machining process method for fining metal crystal grain, its step is followed successively by:
A) extrude: adopt Equal Channel Angular Pressing method, angle of cut Ф=90 ° in mould adopts, external arc angle is the mould of ψ=20 °, and mould channel diameter used is 20mm;
B) forge: concrete steps are:
(1) metal material of extruding is forged on the forging press loaded a die, after forging, place a period of time;
(2) continue more mold exchange, again forge, after forging, place a period of time;
(3) so repeatedly, more mold exchange successively from big to small;
C) drawing: the metal material after forging is placed on the simple and easy drawbench loaded a die and stretches.
Describe the present invention by way of example above, but the invention is not restricted to above-mentioned specific embodiment, all any changes of doing based on the present invention or modification all belong to the scope of protection of present invention.
