[0030] like Figure 1-8 As shown, a heat treatment device for metal parts processing of the present invention comprises a heating chamber 0 and a base 1, wherein the heating chamber 0 is arranged on the left side of the base 1, a rotating column 11 is rotatably mounted on the upper end of the base 1, the rotating column 11 is provided with a rotating assembly, horizontal plates 12 are fixed on both sides of the rotating column 11, and the lower sides of the two horizontal plates 12 are provided with bearing assemblies matching the heating chamber 0;

[0031] The bearing assembly includes a sleeve 13 installed on the lower side of the horizontal plate 12, a sliding cylinder 14 is slidably arranged in the sleeve 13, a sliding rod 15 is slidably arranged in the sliding cylinder 14, a pulling member for pulling the sliding rod 15 to move upward is arranged in the horizontal plate 12, and a bearing frame 16 is installed on the lower side of the sliding cylinder 14 and the lower side of the sliding rod 15;

[0032] A strip rod 2 is fixed in the middle of the rotating column 11, and cover plates 21 located above the supporting frame 16 are fixed at both ends of the strip rod 2. A ventilation duct 22 is opened in the middle of the strip rod 2, and a fan blade 23 is rotatably installed in the ventilation duct 22. A first gear 24 is rotatably installed on the lower side of the strip rod 2, and the fan blade 23 is connected to the first gear 24. A second gear 25 meshing with the first gear 24 is fixed to the base 1.

[0033] When in use, the heating component inside the heating chamber 0 is started, the temperature inside the heating chamber 0 is increased, and the parts to be processed are placed in the carrying frame 16, and the sliding rod 15 is first pulled upward by the pulling member. After the sliding rod 15 slides upward to the upper end of the sliding cylinder 14, the upper end of the lower carrying frame 16 abuts against the bottom of the upper carrying frame 16, and then the sliding rod 15 will drive the sliding cylinder 14 to move upward. After the sliding cylinder 14 moves to the upper end of the sleeve 13, the bottom of the carrying frame 16 is higher than the heating chamber 0, and then the rotating assembly is started to drive the rotating column 11 to rotate, so that the carrying frame 16 carrying the parts rotates to the top of the heating chamber 0, and the pulling of the sliding rod 15 by the pulling assembly is cancelled, then the two carrying frames 16 will slide down into the heating chamber 0 for heat treatment. During the processing, the staff can place the new parts to be processed in the carrying frame 16 on the right side. After the parts in the heating chamber 0 are processed, the above steps can be directly repeated to put the parts to be processed into the heating chamber 0 for processing, thereby reducing waiting time.

[0034] After the heat treatment of the parts in the heating chamber 0 is completed, the pulling component is first started to make the two supporting frames 16 move upward and leave the heating chamber 0, and the upper supporting frame 16 abuts against the cover plate 21, and then the rotating component is started to drive the rotating column 11 to rotate. At this time, the engagement of the first gear 24 and the second gear 25 can drive the fan blades 23 to rotate rapidly to generate wind force, and the outside air will enter the ventilation duct 22 from the bottom of the supporting frame 16 after the heat treatment is completed, and finally blow to the supporting frame 16 on the other side. When the air flows into the ventilation duct 22, it will contact the parts in the supporting frame 16, take away its heat, and then blow to the parts in the supporting frame 16 on the other side. In this way, during the rotation process, the parts after processing can be cooled, and the residual heat of the parts can be used to preheat the parts to be processed.
