The bottom of the loading rack is fixedly connected with a plurality of first ground wheels. A plurality of heating tubes are fixedly connected to the inner walls on both sides of the furnace body. Two first guide rails are fixedly connected to the bottom inner wall of the furnace body. The first ground wheels roll in the first guide rails. A motor is fixedly connected to the outer wall of one side of the furnace body. The output end of the motor is fixedly installed with a lead screw. The lead screw is arranged on the bottom inner wall of the furnace body. A push plate is sleeved on the outer wall of the lead screw in a threaded manner. The push plate can contact the loading rack. A plurality of second ground wheels are fixedly connected to the bottom of the car plate through bolts. Two second guide rails are fixedly connected to the top of the car plate. The first ground wheels can roll in the second guide rails.

[0007] Further, a plurality of support feet are fixedly connected to the bottom outer wall of the furnace body.

[0008] Further, a furnace door is rotatably connected to one side of the furnace body. A handle is fixedly connected to the outer wall of one side of the furnace door. A heat insulation sleeve is sleeved on the outer wall of the handle.

[0009] Further, a push handle is fixedly connected to the left end of the car plate. A non-slip sleeve is sleeved on the outer wall of the push handle.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0021] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.

[0022] Refer to Figures 1 - 3, An annealing furnace, comprising a furnace body 1 and a car plate 14. Inside the furnace body 1, there is a loading rack 11. The loading rack 11 is provided with a plurality of through holes 12. At the bottom of the loading rack 11, a plurality of first ground wheels 10 are fixed by bolts. On both inner walls of the furnace body 1, a plurality of heating tubes 13 are fixed by bolts. The heating tubes 13 are heated to heat the metal machine parts. On the bottom inner wall of the furnace body 1, two first guide rails 9 are fixed by bolts. The first ground wheels 10 roll in the first guide rails 9. On one outer wall of the furnace body 1, a motor 6 is fixed by bolts. The output end of the motor 6 is fixedly installed with a lead screw 7. The lead screw 7 is arranged on the bottom inner wall of the furnace body 1. A push plate 8 is sleeved on the outer wall of the lead screw 7 in a threaded manner. The push plate 8 can contact the loading rack 11. At the bottom of the car plate 14, a plurality of second ground wheels 15 are fixed by bolts. On the top of the car plate 14, two second guide rails 21 are fixed by bolts. The first ground wheels 10 can roll in the second guide rails 21. Driven by the motor 6, the lead screw 7 rotates, driving the push plate 8 to move, and then pushing the loading rack 11 to move outwards. Thus, the first ground wheels 10 roll in the first guide rails 9, and the first ground wheels 10 slide into the second guide rails 21 along the first guide rails 9, moving the loading rack 11 onto the car plate 14, and then realizing the automatic blanking operation.

[0023] On the bottom outer wall of the furnace body 1, a plurality of support feet 2 are fixed by bolts. The furnace body 1 is supported by the support feet 2. One side of the furnace body 1 is rotatably connected with a furnace door 3. On one outer wall of the furnace door 3, a handle 4 is fixed by bolts. An insulating sleeve 5 is sleeved on the outer wall of the handle 4 to prevent the temperature inside the furnace body 1 from being transmitted to the hand through the handle 4 and scalding the hand. At the left end of the car plate 14, a push handle 16 is welded. An anti-slip sleeve 17 is sleeved on the outer wall of the push handle 16. Pushing the push handle 16 makes the second ground wheels 15 roll to push the car plate 14 to one side of the furnace door 3 of the furnace body 1, facilitating subsequent blanking. At the right end of the car plate 14, a baffle 18 is rotatably connected. At both ends of the baffle 18, first clamping blocks 19 are welded. On the top of the car plate 14, two second clamping blocks 20 are welded. The second clamping blocks 20 are clamped with the first clamping blocks 19. The baffle 18 is rotated upwards and the first clamping blocks 19 are clamped with the second clamping blocks 20 to fix the baffle 18, preventing the loading rack 11 from sliding out of the car plate 14 during the moving process. On the bottom inner wall of the furnace body 1, two guiding blocks 22 are welded. The guiding blocks 22 are slidably inserted into the push plate 8. The guiding blocks 22 guide the movement of the push plate 8, improving the stability of the movement of the push plate 8.

[0024] Working principle: When in use, the electronic components of this device are connected to the peripheral controller. First, pull the handle 4 to open the furnace door 3. Then, push the carrier 11 loaded with metal parts into the furnace body 1, and then close the furnace door 3. Then, the peripheral controller controls the heating tube 13 to heat, so as to heat the metal parts. After completion, first, push the push handle 16 to make the second ground wheel 15 roll, so as to push the car plate 14 to one side of the furnace door 3 of the furnace body 1. Then, open the furnace door 3. Then, the outer shell controller controls the motor 6 to work. Driven by the motor 6, the lead screw 7 rotates, so as to drive the push plate 8 to move, and then push the carrier 11 to move outwards. Thus, the first ground wheel 10 rolls in the first guide rail 9, so that the first ground wheel 10 slides into the second guide rail 21 along the first guide rail 9, so as to move the carrier 11 onto the car plate 14, and then realize the automatic blanking operation.
