Problems solved by technology

[0005] There are also serious oxidation phenomena during the metal heating process. The traditional process usually fills the closed heating space with nitrogen and other protective gases to prevent or inhibit the oxidation of the metal surface. The result is the complexity of the device structure and the application cost. improvement

Abstract

The invention relates to a metal plate induction heating device capable of realizing closed-loop temperature control and belongs to the field of metal plate heating. The device comprises three parts including an induction heating power supply, a heating furnace machine and a cooling water system. With the device, scanning heating is performed on a workpiece in an induction heating manner, and the temperature of the workpiece can be increased rapidly and evenly; the upper limit of the workpiece heating temperature can be preset, and the workpiece enters a constant-temperature keeping stage after being heated to a target temperature; an oxidation protection function is realized by clamping the workpiece by the aid of two clamping plates, heating space is not required to be charged with nitrogen in the heating process, and a plate can be prevented from warping in the heating process in the clamping manner; the scanning heating manner is adopted, and the temperature in a certain area instead of the temperature of a single point is measured, so that acquired temperature data are more effective and reliable; and after heating is ended, a workpiece clamping component can be driven by a servo motor to be pushed out of a furnace by a certain distance, and an operator can take away the workpiece conveniently with the structure.

Description

technical field [0001] The invention relates to a sheet metal induction heating device capable of realizing temperature closed-loop control, belonging to the field of sheet metal heating. Background technique [0002] During the heating process of the sheet metal, on the one hand, its internal composition and structure change, and at the same time, its surface state, size, and shape will also change. The defects formed during the heating process are not only related to the success or failure of the entire heat treatment process, but also directly affect the processing technology and performance of the workpiece. [0003] The heating process of the traditional process is carried out in various heat treatment furnaces. In the temperature field, a temperature gradient is established between the heating medium and the workpiece, and the workpiece is heated through three basic physical processes of conduction, convection or radiation. The heating of the workpiece in the furnace...
