It can also protect the rotating support part and ensure that the rotating shaft remains in the correct position, thereby extending the service life of the machine and improving work efficiency. In the process of bearing manufacturing, it needs to be heat treated in a heating furnace.

The adjusting screw is rotated to drive the fixed seat to move downward, so that the internal circular cavity of the fixed seat is sleeved on the top of the positioning seat and contacts the bearing surface, and the bottom of the fixed seat fixes the bearing, which can achieve the stability of the bearing and improve the efficiency of bearing heating.

[0004] However, in actual use of the above-mentioned equipment, the bearings are placed on the positioning seats inside the placement rack to heat them. However, after the batches of bearings are heated, they need to be taken out separately. At the same time, it is difficult to clean the debris on the surface of the bearings during heating, which increases the time for bearing removal and reduces the efficiency of bearing manufacturing. In view of this, we propose a heating furnace that can be heated evenly. Utility Model Content

[0025] In the embodiment of the utility model, a slide groove 3 is provided at the bottom of the inner wall of the heating furnace 1, and the inner part of the slide groove 3 is slidably connected to the outer surface of the slider 4, the top of the slider 4 is fixedly connected to the bottom of the support plate 5, the side wall of the support plate 5 is fixedly connected to the end of the handle 6, the side wall of the support plate 5 is provided with an electromagnetic hanging rod 7, the top of the electromagnetic hanging rod 7 is fixedly connected to the end of the limiting rod 8, and the surface of the electromagnetic hanging rod 7 is penetrated with an air vent 9, the top of the support plate 5 is fixedly connected to one end of the hose 10, the other end of the hose 10 is fixedly connected to the output end of the air pump 11, the input end of the air pump 11 is fixedly connected to the end of the air intake pipe 12, the inside of the air intake pipe 12 is provided with a heating wire 13, the end of the electromagnetic hanging rod 7 is fixedly connected to the end of the threaded rod 19, and the center of the threaded rod 19 is penetrated with a through hole 20, the top of the heating furnace 1 is provided with an exhaust pipe 14, and the surface of the exhaust pipe 14 is provided with a one-way valve 15.

[0026] In one embodiment of the utility model, the outer surface of the threaded rod 19 is threadedly connected to the inner surface of the support plate 5, and a threaded hole matching the support plate 5 is opened at the position where the support plate 5 is connected to the threaded rod 19. The end of the air pump 11 is fixedly connected to the top of the heating furnace 1, and the heating wire 13 is spirally located inside the air inlet pipe 12. The interior of the electromagnetic hanging rod 7 is hollow, and the end of the electromagnetic hanging rod 7 away from the support plate 5 is tilted upward. The interior of the support plate 5 is hollow, and the bottom of the inner wall of the support plate 5 is fixedly connected There is a bottom with an inclined plate 16, and a chip removal hole 17 is opened on the side of the support plate 5 close to the handle 6. The inner surface of the chip removal hole 17 is matched with the sealing plug 18. The end of the inclined plate 16 close to the chip removal hole 17 is lower than the end of the inclined plate 16 away from the chip removal hole 17. Two groups of heating plates 2 are provided, and the two groups of heating plates 2 are respectively located on both sides of the inside of the heating furnace 1. The heating temperature of the heating plate 2, the heating temperature of the heating wire 13 and the flow rate of the wind source output by the air pump 11 are all controlled by the control terminal arranged on the outer surface of the heating furnace 1.

[0027] In the present invention, when the bearing needs to be heated, the door of the heating furnace 1 is first opened, and the handle 6 is manually held to pull the support plate 5 outward. At this time, the hose 10 is in a stretched state, and the slider 4 slides inside the slide groove 3 to provide guidance for the movement of the support plate 5. When the support plate 5 moves a distance, multiple groups of electromagnetic hanging rods 7 are located outside the heating furnace 1. The bearings to be heated are hung by the electromagnetic hanging rods 7. The electromagnetic hanging rods 7 are energized to absorb the debris on the surface of the bearings. Each group of limit rods 8 prevents the bearings from contacting each other. Collision, when the bearing is hung, the support plate 5 is pushed into the heating furnace 1 through the handle 6 to close the door of the heating furnace 1, and the heating plate 2 and the heating wire 13 are started at the same time. The heating plate 2 produces a heat source, and the air pump 11 is started to extract air. After the air is heated by the heating wire 13, hot air is formed and enters the cavity of the support plate 5, and then enters the threaded rod 19 through the through hole 20, and finally enters the electromagnetic hanging rod 7 and is discharged from the multiple groups of air holes 9 to contact the bearing, ensuring that the batch of bearings are evenly heated inside the heating furnace 1. At the same time, the inside of the heating furnace 1 The hot air will be partially discharged outward through the exhaust pipe 14, and the one-way valve 15 prevents the outside air from entering the interior of the heating furnace 1, so as to ensure the temperature inside the heating furnace 1, and the temperature inside the heating furnace 1 is monitored in real time by the temperature detection device of the control terminal. When the bearing is heated, the door of the heating furnace 1 is opened, and the support plate 5 is pulled out of the heating furnace 1 and left to stand for a period of time. After the bearing is cooled, the electromagnetic hanging rod 7 is manually held and the electromagnetic hanging rod 7 is powered off. The debris will fall into the air vent 9 and enter the interior of the support plate 5, and then the electromagnetic hanging rod 7 is pulled out. As the rod 7 rotates, the threaded rod 19 will rotate along with the electromagnetic hanging rod 7 until the threaded rod 19 is separated from the support plate 5, thereby facilitating the unified removal of the heated bearings on the single set of electromagnetic hanging rods 7. The debris on the surface of some bearings will enter the interior of the electromagnetic hanging rod 7 through the air vents 9. Since the electromagnetic hanging rod 7 is slightly tilted upward, the debris will fall into the interior of the support plate 5. Finally, the sealing plug 18 will be pulled away from the chip removal hole 17 through the hanging ring on the sealing plug 18. The debris will slide down to the chip removal hole 17 through the inclination angle of the inclined plate 16 due to gravity and be discharged.

[0028] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not deviate from the spirit of the present invention are within the scope of protection of the present invention.
