The tempering conveyor belt smoothly feeds the workpiece into the tempering furnace for tempering, while the cooling conveyor belt promptly sends the tempered workpiece out of the cooling pool, making the entire tempering process continuous and efficient. 2. By setting up reversing pressure rollers, the bottom mesh conveyor belt is pressed into a parallel position, ensuring that the workpiece will not slide backward significantly when it falls into the cooling conveyor belt. The lifting plate is set up to lift and convey the workpiece to prevent it from slipping. The side baffles on both sides further prevent the workpiece from falling during the conveying process, ensuring the safety of workpiece conveying. 3. By setting up an oil receiving baffle, the cooling oil dripping from the workpiece is collected, preventing the cooling oil from dripping onto the ground and causing pollution. At the same time, the cooling oil can be recycled and reused, reducing production costs. 4. By setting up a support frame, the supporting force of the cooling conveyor belt is increased, and the oil level in the tank can be raised to ensure cooling efficiency.

[0015] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings, so that the technical solution of this utility model can be more easily understood and mastered.

[0016] A mesh belt tempering device for internal spline shafts includes a conveyor belt assembly 1 and a tempering assembly 2. The conveyor belt assembly 1 includes a tempering conveyor belt 3 and a cooling conveyor belt 4. The tempering assembly 2 includes a tempering furnace 17 and a cooling pool 5 disposed on the side of the tempering furnace 17. The tempering conveyor belt 3 is used to feed the workpiece into the tempering furnace 17 and, after tempering, to the cooling pool 5. The cooling conveyor belt 4 is inclined, with one end extending into the cooling pool 5 to receive the workpiece fed in by the tempering conveyor belt 3, and the other end conveying the workpiece out. The inclination angle of the cooling conveyor belt 4 is 15° to 30° to facilitate natural drainage of the workpiece during the conveying process.

[0017] The cooling conveyor belt 4 includes a conveyor roller 6, a deflecting pressure roller 7, and a mesh conveyor belt 8. The mesh conveyor belt 8 is also equipped with lifting plates 9. The deflecting pressure roller 7 is used to press the bottom mesh conveyor belt 8 into a parallel arrangement. The lifting plates 9 are evenly distributed along the conveying direction of the mesh conveyor belt 8 to support the workpiece and prevent it from slipping during inclined conveying.

[0018] The mesh conveyor belt 8 has frames 10 on both sides, and the conveyor rollers 6 are mounted on the frames 10. The upper end of the frames 10 is also equipped with side baffles 11. The side baffles 11 cooperate with the lifting plates 9 to effectively limit the displacement of the workpiece during the conveying process and ensure that the workpiece runs stably along the predetermined trajectory.

[0019] The bottom of the frame 10 is also provided with an oil receiving baffle 12, which is used to receive the cooling oil dripping from the workpiece. The oil receiving baffle 12 is inclined so that the cooling oil can flow into the cooling pool 5 along its surface.

[0020] The cooling pool 5 includes a tank 13, which is connected to the tempering furnace 17. The tank 13 is also provided with an inlet 14 and an outlet 15. The inlet 14 in the cooling pool 5 can be connected to an external cooling oil supply device to continuously replenish the cooling oil in the tank 13, while the outlet 15 can be connected to a recycling device to recycle the used cooling oil to ensure the quality and temperature stability of the cooling oil in the cooling pool 5. A limit block 18 is also provided inside the cooling pool 5 to prevent the workpiece from falling into the bottom of the cooling pool 5.

[0021] A support frame 16 is also installed on the side of the tank 13. The support frame 16 wraps around the outside of the cooling conveyor belt 4, and a sealing gasket is placed between the support frame 16, the tank 13, and the cooling conveyor belt 4. The sealing gasket is made of oil-resistant rubber material, which effectively prevents cooling oil from leaking from the gaps between the support frame 16, the tank 13, and the cooling conveyor belt 4, further improving the sealing performance of the equipment. The addition of the support frame 16 not only enhances the structural stability of the cooling conveyor belt 4 under heavy load, but also allows the cooling oil level in the tank 13 to rise to the lower area of ​​the mesh conveyor belt 8, thereby improving the cooling effect of the workpiece.

[0022] In actual production, temperature sensors can be installed in the tempering furnace 17 and the cooling pool 5 to monitor temperature changes in real time during tempering and cooling. This temperature data can be transmitted to the control system, which automatically adjusts the heating power of the tempering furnace 17 and the liquid inlet and outlet rates of the cooling pool 5 according to preset process parameters to ensure the stability and consistency of the tempering and cooling process.

[0023] Of course, the above are just typical examples of this utility model. In addition, this utility model may have many other specific implementation methods. All technical solutions formed by equivalent substitution or equivalent transformation fall within the scope of protection claimed by this utility model.
