Problems solved by technology

Its obvious shortcomings include: low production efficiency, poor product quality, high scrap rate, high energy consumption, high auxiliary costs, high labor intensity, and environmental pollution.
There is an existing method of quenching the molds together after molding. Although it can handle the heat treatment deformation of the sheet material, it is produced in a separate process, cannot work continuously, and has low production efficiency.

Embodiment Construction

[0018] As shown in Figure 1, the schematic diagram of the existing production process of heat treatment of sheet materials has been described before and will not be repeated here.

[0019] Such as figure 2 , 3, the process diagram of the present invention, the product blank is manually placed on the conveying roller 70, and the conveying roller 70 sends the blank to the roller bottom type continuous heating furnace 72 for heating, and the heated sheet passes through the conveying equipment 72 Automatically enter the cooling tank 73, that is, the sheet material continuous heat treatment control deformation equipment 74 in the quenching pool. After processing, the sheet material is output through the lifting transmission device 75 to leave the production line, that is, the sheet material after quenching is output to the quenching tank through the lifting transmission device.

[0020] As shown in Figures 4, 5 and 6, a pair of chain transmission devices 20 and 30 are set up and d...

Abstract

The present invention discloses deformation controlling method and device for sheet material in continuous heat treatment. Sheet material after being heated to high temperature is first conveyed to the continuous heat treatment deformation controlling device inside the cooling tank, and then held and driven with the deformation controlling device to complete quenching while controlling deformation. The deformation controlling device includes one frame, and one pair of conveying chain units for holding the sheet material. The present invention solves the problem of controlling the deformation of sheet material in continuous heat treatment, and has the advantages of high yield, low power consumption, high quality, low cost, improved work condition and reduced environmental pollution.

Description

technical field [0001] The utility model belongs to a heat treatment deformation control method, in particular to a method for continuously controlling and preventing the deformation of a sheet material during continuous heat treatment of the sheet material. Background technique [0002] The original production process of sheet heat treatment--heating in salt bath furnace--manually take it out and put it in quenching to cool it--take it out and put it in a hydraulic press to pressurize and shape (passive shaping)--wash it to remove salt after taking it out--carry out artificial initial forging school. That is, deformation correction is performed after heat treatment. Its obvious disadvantages are: low production efficiency, poor product quality, high scrap rate, high energy consumption, high auxiliary costs, high labor intensity of workers, and environmental pollution. Existing one uses the mold to carry out quenching treatment at the same time after the mold is formed. Al...
