Description

Technical Field

[0001] The utility model relates to the field of plate processing, in particular to a leveling and heat treatment device for wear-resistant plates. Background Technique

[0002] The unleveled wear-resistant plates may have deformations such as bending and twisting. During assembly, it will cause dimensional deviations, affecting the overall accuracy and performance of the equipment. For example, in mechanical manufacturing, if the wear-resistant plates are used for the support or protection of key parts, the uneven plates will cause gaps or over-tight fits between components, reducing the reliability and service life of the equipment. Therefore, before using the wear-resistant plates, they need to be leveled.

[0003] In the existing method, there is a method of leveling the bent wear-resistant plates by a pressure leveling machine. The specific method is as follows: Place the wear-resistant plate on the workbench, and apply pressure through the hydraulic system to make the plate flat under the action of pressure, so as to achieve the purpose of leveling. When the pressure plate presses down on the wear-resistant plate, the wear-resistant plate is prone to elastic deformation. When the pressure plate detaches from the surface of the wear-resistant plate, the wear-resistant plate returns to the bent state again. The bending arc will become smaller, but it still needs to be leveled twice, resulting in low leveling efficiency and energy waste. Content of the Utility Model

[0007] Preferably, the positioning seat is inserted into the positioning groove, and a perforation is opened on the positioning seat. At the same time, a screw hole is opened on the inner wall of the positioning groove, and the screw hole is adapted to the size of the fixing bolt.

[0011] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0012] 1. When the pressing seat levels the wear-resistant plate in the present utility model, the heating strip inside the leveling seat on the pressing seat starts to work at this time.

Detailed implementation mode

[0019] Please refer to Figures 1-4 , the present utility model provides a leveling heat treatment device for wear-resistant plates, including a leveling seat 5. A fixing piece 52 is fixedly installed at the top of the leveling seat 5, and a pressing seat 51 is fixedly arranged at the bottom of the leveling seat 5. Meanwhile, an insertion port 54 is opened inside the leveling seat 5, and a heating strip 4 is arranged inside the insertion port 54.

[0020] Working principle: When in use, first fixedly connect the fixing piece 52 with the output shaft of the hydraulic cylinder on the pressure straightening machine. Under the action of the hydraulic cylinder, the fixing piece 52 drives the pressing seat 51 to move downward through the leveling seat 5. The bottom of the pressing seat 51 is flat, and the bent wear-resistant plate on the workbench can be leveled; when the pressing seat 51 flattens the wear-resistant plate, at this time, the heating strip 4 inside the leveling seat 5 on the pressing seat 51 starts to work, and the pressing seat 51 is heated through the heating strip 4, so that when the wear-resistant plate is pressed and leveled, heat will be transferred to the wear-resistant plate when contacting the wear-resistant plate; as the temperature of the pressing seat 51 rises, the yield strength of the wear-resistant plate decreases; under the action of the same downward pressure, the wear-resistant plate is more likely to undergo plastic deformation, so as to more effectively eliminate the residual stress and deformation inside the plate. Since the wear-resistant plate is more easily deformed after heating, the required downward pressure can be reduced accordingly, or the straightening effect can be achieved faster under the same pressure; not only energy consumption is saved, but also the working efficiency of straightening is improved; when the heating strip 4 needs to be replaced, at this time, the fixing bolts 6 screwed on both sides of the leveling seat 5 are disassembled, hold the cover plate 1 by hand, and pull out the heating strip 4 and the first support frame 7 and the second support frame 8 thereon inside the insertion port 54, and the purpose of disassembling the heating strip 4 can be completed, and the heating strip 4 can be replaced or repaired.
