Integrated die forging forming technology

Abstract

The invention relates to an integrated die forging forming technology. The integrated die forging forming technology comprises the steps that an aluminum matrix composite material is prepared; and metal which is molten into a liquid phase is poured into a cavity containing the liquid aluminum matrix composite material, cylinders with perpendicular axes of a T-shaped part are filled with the liquid molten metal, liquid filling is performed under the first pressure, the pressure of a punch is less than or equal to the pressure of a hydraulic piston which presses on a left sliding block and a right sliding block, the loading speed of the punch is 15 mm / s, the pressure is kept for 20 s after the punch is loaded, the punch is continuously loaded at the second pressure after the aluminum matrix composite material is solidified so that a solidified metal part can push the left sliding block and the right sliding block to move outwards, after the left sliding block and the right sliding block reach set positions, punch loading is stopped, and two cylindrical parts with axes horizontally unequal in diameter are formed through plastic deformation, wherein the first pressure is less than the second pressure.

Description

technical field [0001] The invention relates to an integrated die forging forming process. Background technique [0002] Although liquid die forging combines the advantages of traditional casting and forging, it is still mainly formed by solidification. Therefore, there is still a certain gap in performance compared with forgings produced by solid die forging. The main reason is the amount of plastic deformation. Small, the organizational state is not a deformed fine-grained structure. In order to improve the performance of the two forming technology parts, in recent years, some scholars have proposed to use casting to make the blank first, and then carry out ordinary hot die forging. This method is only suitable for simple shape parts, and the main purpose is to save materials. [0003] In view of the above-mentioned defects, the designer actively researches and innovates, in order to create an integrated die forging forming process, so that it has more industrial utilizat...
