[0025] Example 1

[0026] Combined with appendix Figure 1 and Figure 2 A profile heat treatment device includes a heating furnace 1 with heat insulation effect. Heating components are respectively connected to both sides of the heating furnace 1. A furnace door 2 is sealed and hinged to the front side of the heating furnace 1. The furnace door 2 is hinged to the bottom front side of the heating furnace 1 by a torsion spring. A viewing window 22 and a handle are connected to the furnace door 2. A fixing rod is connected to the bottom of the heating furnace 1. A telescopic cylinder 3 is hinged to the other end of the fixing rod. The power end of the telescopic cylinder 3 is hinged to the outer wall of the furnace door 2.

[0027] The viewing window 22 in the above structure facilitates direct observation of the heat treatment of the profiles inside the heating furnace 1. The handle facilitates manual operation of the furnace door 2. The furnace door 2 can be opened and closed by driving the telescopic cylinder 3 to extend and retract.

[0028] Combined with appendix Figure 1 and Figure 3 The heating furnace 1 is slidably connected to a support plate 4. The bottom walls of the heating furnace 1 are respectively connected to the first sliders 14. The furnace door 2 is connected to the second sliders 15 opposite to each other. The bottom end of the support plate 4 is connected to a guide block 18. The guide block 18 is slidably engaged with the first sliders 14 and the second sliders 15. The first slider 14 is hinged to a first hinge rod 16 near the second slider 15. The other end of the first hinge rod 16 is hinged to a second hinge rod 17. The other end of the second hinge rod 17 is hinged to the second slider 15. The first slider 14, the second slider 15, the first hinge rod 16 and the second hinge rod 17 are collinear and all are slidably engaged with the guide block 18.

[0029] The bearing plate 4 in the above structure can drive the profile to slide stably out of the heating furnace 1.

[0030] Combined with appendix Figure 4 and Figure 5The heating furnace 1 is equipped with a drive assembly that can drive the support plate 4 to slide. The drive assembly includes a motor 5 connected to the bottom end of the bottom wall of the heating furnace 1. The power output end of the motor 5 is connected to a first sprocket 6. The top end of the bottom wall of the heating furnace 1 is rotatably connected to a second sprocket 7. The sides of the furnace door 2 are rotatably connected to a third sprocket 8 and a fourth sprocket 9, respectively. Chains 11 are connected to the first sprocket 6, the second sprocket 7, the third sprocket 8, and the fourth sprocket 9. A fifth guide wheel 12 and a sixth guide wheel 13 are connected to the hinge of the heating furnace 1 near the furnace door 2. The chain 11 cooperates with the fifth guide wheel 12 and the sixth guide wheel 13. A fixing block 10 is connected to the bottom end of the support plate 4. The support plate 4 is connected to the chain 11 through the fixing block 10. The support plate 4 can slide onto the unfolded furnace door 2 under the drive of the drive assembly.

[0031] The configuration of the drive components in the above structure facilitates the automatic entry and exit of the support plate 4 into the heating furnace 1, realizing automated material feeding and discharging and avoiding safety risks caused by manual operation.

[0032] Example 2

[0033] Based on Example 1, combined with Appendix Figure 3 and Figure 4 The heating furnace 1 is connected to a circulation component that can circulate the air inside the heating furnace 1. The circulation component includes a main channel 19 connected to the rear side of the heating furnace 1. Return air channels 20 are respectively connected to both sides of the main channel 19. The other end of the return air channel 20 is connected to both sides of the heating furnace 1. A circulation fan 21 is connected inside the main channel 19.

[0034] The arrangement of the circulation components in the above structure facilitates rapid and even heat distribution in the heating furnace 1, preventing hot air from being drawn out of the heating furnace 1 and causing safety risks.

[0035] The specific usage method is as follows:

[0036] Then, the support plate 4 can be exported via the drive assembly. After the profile is placed, the drive assembly can be reversed to automatically drive the support plate 4 and the profile into the heating furnace 1 for heat treatment. This avoids the safety risks of manual approach to the heating furnace 1 during the loading and unloading process. By starting the motor 5, the motor 5 drives the first sprocket 6. The first sprocket 6, the second sprocket 7, the third sprocket 8, and the fourth sprocket 9 work together to drive the chain 11. The fifth guide wheel 12 and the sixth guide wheel 13 are both sprockets that work with the chain 11. The fifth guide wheel 12 and the sixth guide wheel 13 are designed to guide the chain 11, allowing the furnace door 2 to close and open smoothly. When started, the chain 11 can be driven. The chain 11 drives the bearing plate 4 and the profile to slide into or out of the heating furnace 1 through the fixed block 10, which facilitates automatic feeding and discharging. The coordinated arrangement of the first slider 14, the second slider 15, the first hinge rod 16 and the second hinge rod 17 makes the hinge angle between the first hinge rod 16 and the second hinge rod 17 smaller when the furnace door 2 is closed. This facilitates the folding of the first hinge rod 16 and the second hinge rod 17 in conjunction with the closing of the furnace door 2. It also facilitates the sliding penetration of the guide block 18 in conjunction with the first slider 14 and the second slider 15, so that the bearing plate 4 can slide along the length of the guide rod.

[0037] The circulation component facilitates rapid and even heat distribution within the furnace 1. By activating the circulation fan 21, air from the furnace 1 is directed into the main channel 19 and then returned to the furnace 1 via the return air channel 20. This accelerates the airflow within the furnace 1, improves the temperature uniformity of the furnace 1, and prevents hot air from being directly exhausted through the open furnace door 2, thus reducing energy waste and avoiding safety risks.
