[0025] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0026] Please see Figure 1 - Figure 8 This utility model provides an embodiment of a heat treatment device for metal automotive parts processing, including a heating chamber body 1, a support plate 4 fixedly connected to the bottom of the heating chamber body 1, a tray frame 5 disposed on the heating chamber body 1, a sealing assembly disposed on the heating chamber body 1, an air suction hopper 21 fixedly connected to the heating chamber body 1, a first fixed outer box 22 fixedly connected to the heating chamber body 1, a first connecting pipe 23 fixedly connected between the first fixed outer box 22 and the air suction hopper 21, a sliding frame 24 slidably connected to the first fixed outer box 22, and a component disposed on the sliding frame. The components include: a filter plate 25 on the 24th floor; a limiting assembly on the first fixed outer casing 22; a second fixed outer casing 26 fixedly connected to the support plate 4; a second connecting pipe 27 fixedly connected between the second fixed outer casing 26 and the first fixed outer casing 22; a guide assembly on the second fixed outer casing 26; a centrifugal fan body 28 fixedly connected to the support plate 4; a third connecting pipe 29 fixedly connected between the centrifugal fan body 28 and the second fixed outer casing 26; a sealing assembly that seals the heating box body 1; and a snap-fit ​​assembly that restricts the sliding out of the filter plate 25. The filter plate 25 performs preliminary filtration of the exhaust gas, and the activated carbon adsorption box body 220 further adsorbs and filters the exhaust gas. During use, after placing the parts on the tray rack 5, the tray rack 5 is slid into the heating box body 1, and the heating box body 1 is closed. The workpiece is then heated by the heating box body 1. After completion, the sealing assembly is opened, allowing the through hole at the bottom of the suction hopper 21 to open. The centrifugal fan body 28 then provides suction, causing the hot air generated inside the heating box body 1 to pass through the suction hopper 21 and the first connecting pipe 23 into the first fixed outer box 22. Inside, as the hot air passes through the sliding frame 24 inside the first fixed outer casing 22, it is initially filtered by the impurity filter plate 25. After the initial filtration, the hot air enters the second fixed outer casing 26 through the second connecting pipe 27. When the hot air enters the second fixed outer casing 26, it is guided by the guide component and then enters the second fixed outer casing 26 for further filtration by the activated carbon adsorption box body 220. The activated carbon stored inside the activated carbon adsorption box body 220 filters particulate impurities in the waste gas and then discharges it through the outlet of the centrifugal fan body 28.

[0027] Please see Figure 1 - Figure 7In this embodiment, three sliding frames 24 and three impurity filter plates 25 are provided. The three sliding frames 24 are slidably connected to the first fixed outer box 22, and the three impurity filter plates 25 are sequentially arranged on the three sliding frames 24. The three layers of sliding frames 24 and impurity filter plates 25 are used to fully filter larger impurities, preventing some larger impurities from entering the second fixed outer box 26 and causing blockage. The guide assembly includes a first motor 210 fixedly connected to the support plate 4, a rotating disk 211 fixedly connected to the output end of the first motor 210, a fixed rod 212 fixedly connected to the rotating disk 211, a sliding rack 213 fixedly connected to the second fixed outer box 26, and a fixed rod 212. The system includes a connecting block 214 connected to the sliding rack 213, a rotating gear 215 meshing with the sliding rack 213, a guide plate 216 fixedly connected to the rotating gear 215, a fixed rod 212 slidably connected to the connecting block 214, and a guide plate 216 rotatably connected to the second fixed outer casing 26. When the first motor 210 operates, it drives the rotating disk 211 and the fixed rod 212 to rotate. The fixed rod 212 and the connecting block 214 cooperate to drive the sliding rack 213 to slide back and forth. The guide plate 216 swings to guide the gas entering the second fixed outer casing 26. The guiding assembly guides the gas about to enter the second fixed outer casing 26, making the gas more uniform. Upon entering the second fixed outer casing 26, the activated carbon adsorption box body 220 filters the gas, preventing concentrated gas from entering the second fixed outer casing 26 and causing over-filtration in some areas and low utilization in others. The second fixed outer casing 26 has a guide groove at the relative position of the sliding rack 213, on which the sliding rack 213 is slidably connected. The groove restricts the sliding of the sliding rack 213, preventing it from tilting and affecting the meshing between the sliding rack 213 and the rotating gear 215. The connecting block 214 has a limit groove at the relative position of the fixed rod 212, on which the fixed rod 212 is slidably connected. The fixed rod 212 is attached to the slide groove, which restricts the sliding of the fixed rod 212 and prevents the fixed rod 212 from disengaging from the connection with the connecting block 214. The fixed rod 212 and the connecting block 214 cooperate to drive the sliding rack 213 to slide back and forth. The limiting component includes a fixed shell 217 fixedly connected to the first fixed outer box 22, a sliding block 218 slidably connected to the fixed shell 217, and a first spring 219 fixedly connected between the sliding block 218 and the fixed shell 217. The sliding block 218 restricts the sliding of the sliding frame 24, and the first spring 219 provides a pushing force to the sliding block 218 to push the sliding block 218 to more firmly restrict the sliding of the impurity filter plate 25.

[0028] Please see Figure 3 , Figure 8In this embodiment, the sealing assembly includes a second motor 31 fixedly connected to the heating chamber body 1, a threaded rod 32 fixedly connected to the output end of the second motor 31, a sealing plate 33 slidably connected to the heating chamber body 1, and a connecting bracket 34 fixedly connected to the sealing plate 33. The connecting bracket 34 is threadedly connected to the threaded rod 32. During heat treatment, the heating chamber body 1 is sealed by the sealing plate 33. The second motor 31 drives the threaded rod 32 to rotate, adjusting the sliding of the connecting bracket 34. During use, the sealing plate 33 slides. During heat treatment, the sealing plate 33 closes to seal the heating chamber body 1, preventing hot air from escaping through the suction hopper 21 and affecting the heating efficiency. After heat treatment, the sealing plate 33 is opened, and the centrifugal fan body 28 provides suction to draw out the hot air, filter it, and discharge it. The heating chamber body 1 has a sliding groove at the relative position of the sealing plate 33. The sealing plate 33 is slidably connected to the sliding groove, and the sliding groove guides the sliding of the sealing plate 33, allowing the sealing plate 33 to slide linearly inside the heating chamber body 1.

[0029] During operation, after placing the parts on the tray frame 5, the tray frame 5 is slid into the heating chamber body 1, and the heating chamber body 1 is closed. The workpiece is then heated by the heating chamber body 1. The second motor 31 drives the threaded rod 32 to rotate. When the threaded rod 32 rotates, it connects with the connecting bracket 34, causing the sealing plate 33 to slide and open. The centrifugal fan body 28 provides suction, allowing the hot air generated inside the heating chamber body 1 to enter the first fixed outer box 22 through the suction hopper 21 and the first connecting pipe 23. Inside the first fixed outer box 22, the hot air is initially filtered by the impurity filter plate 25 as it passes through the sliding frame 24. The pre-filtered hot air then enters the second fixed outer box 26 through the second connecting pipe 27. As the hot air enters the second fixed outer box 26, it is further heated by the first motor. The operation of motor 210 drives the rotating disk 211 to rotate. When the rotating disk 211 rotates, it drives the fixed rod 212 to rotate. When the fixed rod 212 rotates, it cooperates with the connecting block 214 to drive the sliding rack 213 to reciprocate. When the sliding rack 213 moves, it meshes with the rotating gear 215, which drives the guide plate 216 to swing back and forth, guiding the gas into the second fixed outer box 26. The activated carbon adsorption box body 220 further filters the gas. The activated carbon stored in the activated carbon adsorption box body 220 filters particulate impurities in the waste gas before it is discharged through the outlet of the centrifugal fan body 28. After completion, the heating box body 1 is opened, and the tray frame 5 slides open to take out the workpiece. After placing a new batch of workpieces, the second motor 31 is used to close the sealing plate 33 for secondary heat treatment.

[0030] Through the above steps, before opening the heating chamber body 1 to complete the heat treatment work, the centrifugal fan body 28 provides suction, and the gas is filtered through the impurity filter plate 25 and the activated carbon adsorption box body 220 to solve the problem that some special automotive parts will generate harmful gases when the materials are heated and volatilized during heat treatment, which will affect the surrounding staff and environment.
