Full-automatic continuous type secondary heating device for semisolid metal blanks

Abstract

The invention relates to a full-automatic continuous type secondary heating device for semisolid metal blanks and belongs to the technical field of semisolid metal processing. The full-automatic continuous type secondary heating device comprises an induction heating power supply, an induction heating mechanism, a material carrying and conveying mechanism, a blank rotating mechanism and an automatic feeding mechanism. The induction heating mechanism comprises seven induction heating coils and a drive device, the induction heating coils are arranged on the drive device, the seven induction heating coils and one vacancy are evenly distributed at 45 degrees in the circumferential direction, and the coils are connected in series and are connected with the induction heating power supply. The blanks are placed on the material carrying and conveying mechanism through the automatic feeding mechanism and sequentially heated by the seven induction heating coils, and the blank rotating mechanism is connected to the material carrying and conveying mechanism, so the blanks can be in a continuous rotation state in the heating process. The full-automatic continuous type secondary heating device can meet requirements for quick heating, even temperature and full-automatic heating in the aluminum alloy semisolid thixotropic processing process and has the advantages of being safe to operate, stable in running and easy to control.

Description

technical field [0001] The invention relates to an automatic continuous secondary heating device for semi-solid metal blanks, in particular to a fully automatic continuous secondary heating device for semi-solid thixotropic processing of alloy blanks, belonging to the technical field of metal semi-solid processing. Background technique [0002] Metal semi-solid processing technology is a new type of processing and forming method between traditional solid-state processing technology (such as rolling, extrusion, forging, etc.) and liquid forming technology (such as casting, etc.). Its core technical features include: 1) the forming temperature is between the solid liquidus temperature; 2) the grain shape is different from the dendritic grain shape in the general solidified structure, but is non-dendritic and nearly spherical. grain shape. Due to the above characteristics, the semi-solid processing technology has the advantages of less casting defects, low porosity, easy proce...

AI Technical Summary

Problems solved by technology

However, this kind of heating device has an end heating effect on the billet, and it is difficult to achieve a consistent temperature distribution. It is difficult to clamp and transfer the semi-solid state of the billet after heating, and it is difficult to realize the connection with the subsequent forming process. Manual feeding cannot realize the completeness of the entire heating process. Automation is not conducive to the promotion and large-scale application of semi-solid processing technology
