[0002] Heat treatment is a metal heat treatment process that involves heating, holding, and cooling materials in a solid state to obtain the desired microstructure and properties.

[0003] In existing product heat treatment processes, brackets are typically used to support the workpiece to control product deformation. However, due to the two-point support of the bracket, the workpiece will still deform during the heat treatment process, and the amount of deformation cannot be controlled within the range required by the drawings, thus failing to achieve product deformation stability. Therefore, a heat treatment anti-bending device is proposed to address the above problems. Utility Model Content

[0005] The technical solution adopted by this utility model to solve its technical problem is as follows: The heat treatment anti-bending device of this utility model includes an insulating base plate. Two adjusting components are provided on the top of the insulating base plate. One adjusting component has a fixing frame on its top, and the other adjusting component has a fixing plate on its top. Three heat-resistant bending components are provided inside the fixing plate. The workpiece body is provided inside the fixing plate. An induction coil is provided inside the fixing frame. A transmission component is provided on the top of the insulating base plate. The transmission component is connected to the adjusting components.

[0006] Preferably, the adjusting assembly includes a fixed cylinder, a lead screw, and a rotating wheel. The fixed cylinder is fixedly connected to the top of the insulating base plate, the lead screw is slidably connected inside the fixed cylinder, the rotating wheel is rotatably connected to the top of the fixed cylinder, and the rotating wheel is threadedly connected to the outside of the lead screw.

[0007] Preferably, the heat-resistant bending assembly includes an adjusting bolt, a saddle block, a roller, and an anti-rotation pin. The adjusting bolt is threadedly connected to the inside of the fixed plate, the saddle block is slidably connected to the inside of the fixed plate, the roller is rotatably connected to the inside of the saddle block, and the anti-rotation pin is inserted into the inside of the saddle block.

[0011] The advantages of this utility model are:

[0012] 1. In use, place the workpiece body through the fixed frame and fixed plate, and then rotate the adjusting bolt to adjust the position of the saddle block by adjusting the threaded engagement between the adjusting bolt and the fixed plate. At the same time, adjust the position of the rollers so that the rollers fit against the workpiece body, and the workpiece rotates around the center of the three rollers to achieve three-point contact.

The heat-resistant bending component 5 achieves three-point contact, preventing the workpiece body 6 from being misaligned during clamping. The height of the fixed plate 4 and the fixed frame 3 can be adjusted by adjusting the component 2 and the transmission component 7.

[0022] Furthermore, the adjusting assembly 2 includes a fixed cylinder 201, a lead screw 202, and a rotating wheel 203. The fixed cylinder 201 is fixedly connected to the top of the insulating base plate 1, the lead screw 202 is slidably connected to the inside of the fixed cylinder 201, and the rotating wheel 203 is rotatably connected to the top of the fixed cylinder 201, and the rotating wheel 203 is threadedly connected to the outside of the lead screw 202.

[0023] During operation, the rotating wheel 203 is directly threaded with the lead screw 202, and the lead screw 202 cannot rotate. Then the lead screw 202 will move in a numerical direction, thereby adjusting the position of the fixed plate 4 and the fixed frame 3.

[0024] Furthermore, the heat-resistant bending assembly 5 includes an adjusting bolt 501, a saddle block 502, a roller 503, and an anti-rotation pin 504. The adjusting bolt 501 is threadedly connected to the inside of the fixed plate 4, the saddle block 502 is slidably connected to the inside of the fixed plate 4, the roller 503 is rotatably connected to the inside of the saddle block 502, and the anti-rotation pin 504 is inserted into the inside of the saddle block 502.

[0025] During operation, the workpiece body 6 is placed through the fixed frame 3 and the fixed plate 4. Then, the adjusting bolt 501 is rotated to adjust the position of the saddle block 502 by adjusting the threaded engagement between the adjusting bolt 501 and the fixed plate 4. At the same time, the position of the roller 503 is adjusted so that the roller 503 fits against the workpiece body 6, and the workpiece rotates around the center of the three rollers 503 to achieve three-point contact. This avoids the workpiece body 6 being misaligned during clamping and ensures that it always moves along the axis of the roller 503 during the heat treatment process, reducing bending deformation during heat treatment.

[0028] Furthermore, a groove 9 is provided inside the fixed cylinder 201, and a slide plate 10 is fixedly connected to the outside of the lead screw 202. The slide plate 10 is slidably connected inside the groove 9.

[0030] Furthermore, the roller 503 is made of ceramic;

[0031] When in operation, ceramics have many advantages such as excellent insulation, corrosion resistance, high temperature resistance, high hardness, low density, and radiation resistance.

[0032] Working principle: In use, the workpiece body 6 is placed through the fixed frame 3 and the fixed plate 4. Then, the adjusting bolt 501 is rotated to adjust the position of the saddle block 502 through the threaded engagement between the adjusting bolt 501 and the fixed plate 4. At the same time, the position of the roller 503 is adjusted, so that the roller 503 fits against the workpiece body 6, and the workpiece rotates around the center of the three rollers 503 to achieve three-point contact, avoiding the workpiece body 6 from being misaligned during clamping. During the heat treatment process, it always moves along the axis of the roller 503. The rotating wheel 203 is directly threaded with the lead screw 202, and the lead screw 202 cannot rotate. Then the lead screw 202 will move in the numerical direction, thereby adjusting the position of the fixed plate 4 and the fixed frame 3. The rotating gear 702, through the meshing between the gear 702 and the toothed belt 703, and through the transmission of the toothed belt 703, allows the two lead screws 202 to rotate, which facilitates the simultaneous adjustment of the height.
