Although there is a horizontal tempering equipment at present, the bearing ring is continuously sent in through the conveying roller, after the tempering heating, the bearing ring is continuously conveyed to the heat preservation section for heat preservation. However, the horizontal tempering equipment needs to occupy more ground space, and the two ends of the horizontal tempering equipment are generally fully open, and the heat preservation effect is relatively poor.

Side shells 6 are provided on both sides of the furnace body 1 corresponding to the side grooves 3. Heating grooves 7 are formed on the inner sides of the furnace body 1 adjacent to the side grooves 3, electric heating rods 8 are arranged on the inner side of each heating groove 7, two layers of support plates 5 are on the upper side of each heating groove 7, and three layers of support plates 5 are on the lower side of each heating groove 7. A heating element is placed on the inner side of the furnace cavity 2 above the support plates 5. A plate frame 14 is provided, and a discharge chute 9 is opened on the lower side of the furnace body 1. After heating, the plate frame 14 can be automatically lowered into the heat preservation area, and a new batch of bearing rings can be dropped from above, thus enabling continuous heating and increasing the efficiency of bearing tempering. In addition, it does not occupy a large amount of ground space. The plate frame 14 is located above and below the furnace cavity 2, which shields the furnace cavity 2 during the transportation process, preventing heat loss and providing a relatively high heat preservation effect. A conveying device 10 is provided on the lower inner side of the discharge chute 9. The gap between the upper side of the conveying device 10 and the upper side of the discharge chute 9 is greater than the height of the plate frame 14. The conveying device 10 facilitates the transportation of the dropped plate frame 14. The sides of the pallet 0 do not contact the pallet 5. The bottom row of pallets 5 is lower than the top of the conveyor 10 to avoid the conveyor 10 blocking the pallets 5 and to facilitate the pallet 5 falling directly onto the conveyor 10 when it reaches the last layer. An inlet 11 is provided on the upper side of one side of the furnace body 1, and the inlet 11 extends from the furnace body 1 to the furnace cavity 2. A platform plate 13 is provided on the side of the furnace body 1 below the inlet 11. The platform plate 13 can be connected to a conveyor belt, a ladder, or other processing platform to place the conveyed pallet 14. Then, the pallet 14 is easily fed onto the first layer of pallets 5 through the inlet 11. Auxiliary supports are provided at equal intervals on the lower inner side of the inlet 11. The auxiliary roller 12 has its upper side flush with the height of the first layer support plate 5. The auxiliary roller 12 pushes the plate frame 14, making it easier to push. The plate frame 14 includes a metal plate 141. Positioning rods 143 are equidistantly arranged on the upper side of the metal plate 141.

The ceramic plate 142 is used to provide better heat insulation between different layers of the plate frame 14, thereby reducing the heat loss from the upper and lower openings of the furnace cavity 2.

[0034] Working principle and usage process of this utility model:

[0035] In use, place the bearing ring on the upper side of the plate frame 14, then place the plate frame 14 from the upper side of the furnace cavity 2 onto the uppermost pallet 5. The pallets 5 on both sides of the lower side of the plate frame 14 provide support. Start the metal conveyor belt device 4. The metal conveyor belt device 4 slowly moves the plate frame 14 down along the furnace cavity 2 via the pallets 5. When the plate frame 14 reaches the heating tank 7, stop the metal conveyor belt device 4. Start the electric heating rod 8 to temper and heat the bearing ring on the plate frame 14. After heating is completed, continue to move the plate frame 14 down. There are a total of six layers of pallets 5 on the outer side of the metal conveyor belt device 4 that can circulate. The first layer is the feeding area, the second layer is the preheating area, and the third layer corresponds to the heating tank 7 and belongs to the heating area. The fourth and fifth layers are insulation zones, and the last layer, located at the discharge chute 9, is the unloading zone. After heating, the material can be automatically lowered into the insulation zone, and a new batch of bearing rings can fall from above, thus enabling continuous heating and increasing the efficiency of bearing tempering. Furthermore, it does not occupy a large amount of floor space. The furnace cavity 2 is shielded by racks 14 above and below during transport, preventing heat loss and providing relatively high insulation. Additionally, a conveyor device 10 is installed on the lower inner side of the discharge chute 9. The gap between the upper side of the conveyor device 10 and the upper side of the discharge chute 9 is greater than the height of the racks 14, facilitating the transport of the falling racks 14. During use, the sides of the conveyor 10 do not contact the pallets 5, and the bottom row of pallets 5 is lower than the top of the conveyor 10 to avoid the conveyor 10 blocking the pallets 5. This also facilitates the pallet rack 14 falling directly onto the conveyor 10 when the pallets 5 fall to the last layer. In addition, during use, an inlet 11 is provided on the upper side of one side of the furnace body 1, which extends from the furnace body 1 to the furnace cavity 2. A platform plate 13 is provided on the side of the furnace body 1 below the inlet 11. The platform plate 13 can be connected to a conveyor belt, ladder, or other processing platform to place the conveyed pallet rack 14. Then, the pallet rack 14 is easily fed onto the first layer of pallets 5 through the inlet 11. The lower inner side of the inlet 11 is equidistantly provided with An auxiliary roller 12 is provided, with its upper side flush with the height of the first layer support plate 5. The auxiliary roller 12 pushes the plate frame 14 more effortlessly. In addition, the plate frame 14 includes a metal plate 141, with positioning rods 143 evenly arranged on the upper side of the metal plate 141. By fitting a bearing ring of a certain size onto the positioning rod 143, it is easy to store and stabilize the bearing ring. Furthermore, during use, a ceramic plate 142 is provided on the lower side of the metal plate 141. The metal plate 141 and the ceramic plate 142 are all in contact with the inner wall of the furnace cavity 2. The ceramic plate 142 is provided to provide better heat insulation between different layers of the plate frame 14, thereby reducing heat loss from the upper and lower openings of the furnace cavity 2.
