Pre-processing system and pre-processing method for heat formation operation

Abstract

A pre-processing system and a pre-processing method for heat formation operation are provided to overcome the issue of temperature reduction of the workpiece during the movement of the workpiece in the conventional heat formation operation. The system includes at least one temperature control module having a heater, at least one conveying unit coupled to the temperature control module, and a control unit coupled with the temperature control module and the conveying unit, wherein the heater heats the workpiece on the temperature control module according to a temperature control mode. The conveying unit conveys the temperature control module and the workpiece to a convey position. The control unit adjusts the temperature control mode and sets the convey position according to a production condition.

Description

technical field [0001] The invention relates to a metal processing and forming technology, in particular to a pre-processing system and method for controlling a workpiece to have a suitable processing temperature for thermal forming. Background technique [0002] In the process of press forming, such as: forging, stamping and other methods, the workpiece will produce reverse elastic deformation, and this springback phenomenon is an important factor affecting the accuracy of the completed workpiece. By heating the workpiece, the stress and strain of the workpiece can be reduced during the compression deformation stage, thereby improving the plastic deformation ability of the workpiece, reducing the rebound amount of the workpiece deformation, and ensuring the machining dimensional accuracy of the workpiece. In addition, after the heated workpiece is press-formed in the mold, it can be cooled and quenched to improve the strength of the workpiece. [0003] In the above-mention...

AI Technical Summary

Problems solved by technology

However, when the general forming mold is used for in-mold quenching, the heating device is not suitable for direct heating of the mold. The workpiece can only be heated in the heating furnace, and then transported to the forming mold for pressurization and cooling treatment, resulting in extension of the production line and production. poor efficiency

In addition, the workpiece during the transportation process is prone to heat loss, resulting in the inability to ensure uniform and appropriate temperature of each part during the forming and quenching of the workpiece, thereby reducing the quality of processing
