[0026] Specifically, the fixed rod 8 is driven to rotate by the motor 2, thereby driving the driving gear 9 to rotate. Since the driving gear 9 is meshed with the rack 6, the rotation of the driving gear 9 drives the rack 6 to move downward, thereby driving the pulley assembly to slide downward synchronously on the inner walls of the slide plate 1 3 and the slide plate 2 10, the pulley 14 slides on the inner wall of the slide plate 1 3, the pulley 2 16 slides on the bottom of the slide plate 1 3, the pulley 14 and the pulley 2 16 are responsible for the sliding guidance of the pulley assembly on the inner wall of the slide plate 3, the pulley assembly is fixedly connected to the sealing door 5, thereby driving the sealing door 5 to move downward, the slide plate 1 3 and the slide plate 2 10 have a turning point at the bottom, causing the sealing door 5 to move in the vertical direction while also moving in the horizontal direction, thereby achieving the effect of sealing the heat treatment furnace door.
[0027] Reference Figure 2 and Figure 3 The pulley assembly includes a pulley 14, a rotating shaft 15 and a pulley 2 16, the outer wall of the rotating shaft 15 is rotatably connected to the inside of the sliding block 13, the inner wall of the pulley 14 is fixedly connected to both ends of the rotating shaft 15, and the inner wall of the pulley 2 16 is rotatably connected to the inside of the sliding block 13;
[0028] Specifically, pulley 14 slides on the inner wall of the slide plate 1 3, and pulley 2 16 slides on the bottom of the slide plate 1 3. Pulley 14 and pulley 2 16 are responsible for the sliding guidance of the pulley assembly on the inner wall of the slide plate 1 3.

Wedge-shaped blocks are provided on both sides of the slider 24, which fit with the inner wall of the slider 1 22. Protrusions are provided on both sides of the slider 1 22 to fit with the slide rail 21, so that the slider 1 22 can move horizontally on the slide rail 21, and the side of the slider 1 22 is provided with a slope.

The top of the slider 1 22 is fixedly connected to the clamping block 23, causing the clamping block 23 to move inward on the inner wall of the slide rail 21 to clamp the parts, and then the threaded rod 18 is driven to rotate by the motor 2 17, driving the movable block 11 to move toward the inside of the furnace body 1. When it moves to the processing position, the top clamping mechanism is driven to rotate by the motor 3 19 to achieve the effect of uniform heating.
[0031] Working principle: First, the parts to be heat treated are placed in the middle of the clamping block 23, and the cylinder 20 contracts, driving the top slider 24 to move downward, thereby driving the sliders 1 22 on both sides to move inward.

When it moves to the processing position, the top clamping mechanism is driven to rotate by the motor 3 19 to achieve the effect of uniform heating, and then the fixed rod 8 is driven to rotate by the motor 1 2 , thereby driving the driving gear 9 to rotate.
