[0029] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0030] Reference Figure 1 , Figure 3 , Figure 5 and Figure 6 This utility model provides a tempering furnace that is easy to handle, including a furnace body 1, a rotating shaft 2, a sealing door 3, and a material rack 4. The rotating shaft 2 is rotatably connected to one end of the furnace body 1, and the sealing door 3 is fixed to the outside of the rotating shaft 2 to seal the furnace body 1. The sealing door 3 is installed through the rotating shaft 2 and can be opened and closed by controlling the rotation of the rotating shaft 2. The material rack 4 is slidably connected inside the furnace body 1, and the material rack 4 is used to conveniently place the workpieces that need to be tempered. Two sliding grooves 13 are opened on both sides of the inner wall of the furnace body 1. Sliding blocks 14 are installed on both sides of the top and bottom of the material rack 4. The sliding blocks 14 are slidably connected to the sliding grooves 13. The cooperation between the sliding blocks 14 and the sliding grooves 13 allows the material rack 4 to slide stably inside the furnace body 1, and prevents the material rack 4 from falling out of the furnace body 1.

[0031] The furnace body 1 has grooves 11 on three sides of its inner wall. Heating rods 12 are installed at equal intervals inside the grooves 11, which can be used to heat the workpieces placed inside the furnace body 1. Support legs 15 are installed at the four corners of the bottom of the furnace body 1. Positioning holes are opened at the four corners of the top of the support legs 15. The support legs 15 are used to place the equipment, and the positioning holes can be used to fix the equipment stably in the designated position, while preventing the furnace body 1 from tipping over when the material rack 4 extends to the outside of the furnace body 1.

[0032] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4In one aspect of this embodiment, a door opening assembly is provided on the outer side of the furnace body 1. The door opening assembly is used to rotate the sealing door 3 and the rotating shaft 2. The door opening assembly includes two cylinders 5 and two U-shaped brackets 6. Both cylinders 5 are rotatably connected to the outer side of the furnace body 1, and both U-shaped brackets 6 are fixedly connected to the outer side of the rotating shaft 2. The piston rods of the cylinders 5 are rotatably connected to the corresponding U-shaped brackets 6. By utilizing the simultaneous operation of the two cylinders 5, in conjunction with the U-shaped brackets 6, the rotating shaft 2 can be driven to rotate at one end of the furnace body 1, thereby driving the sealing door 3 to complete the opening and closing action.

[0033] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 7 In one aspect of this embodiment, two connecting rod assemblies are provided at the top and bottom of the material rack 4, both inside the furnace body 1. The top and bottom of the material rack 4 are made of heat-insulating material (ceramic material or fire-resistant fiberglass), which can protect the connecting rod assemblies at the top and bottom of the material rack 4 to a certain extent. The connecting rod assemblies are used to cooperate with the sealing door 3 to extend the material rack 4 to the outside of the furnace body 1 or into the interior of the furnace body 1. The connecting rod assembly includes a push groove 7, a push rod 8, a push column 9, and a pull rod 10. The push groove 7 is formed at the top and bottom of the material rack 4. The push rod 8 is rotatably connected to the inner wall of the furnace body 1. The push column 9 is installed on the end of the push rod 8 away from the inner wall of the furnace body 1, and each push column 9 extends into the interior of the corresponding push groove 7. The push column 9 is set with a cylindrical structure, allowing it to move and rotate within the push groove 7. The pull rod 10 is rotatably connected to the inner wall of the sealing door 3, and the end of the pull rod 10 away from the sealing door 3 is rotatably connected to one end of the corresponding push rod 8. When the sealing door 3 is opened, the pull rod 10 drives one end of the push rod 8 to swing, causing the push rod 8 to rotate with the end connected to the inner wall of the furnace body 1 as the fulcrum. At the same time, the material rack 4 is pushed to move under the cooperation of the slider 14 and the slide groove 13 by the cooperation of the push column 9 and the push groove 7, so that it extends to the outside of the furnace body 1. When the sealing door 3 is closed, the pull rod 10 drives one end of the push rod 8 to swing in the opposite direction. At the same time, the material rack 4 is pushed to move in the opposite direction under the cooperation of the slider 14 and the slide groove 13 by the cooperation of the push column 9 and the push groove 7, so that it retracts into the interior of the furnace body 1.

[0034] Working principle:

[0035] When using the device, first place it on the support leg 15 and stabilize its position through the positioning hole, then power on the device.

[0036] When it is necessary to place a workpiece, the two cylinders 5 are controlled to work simultaneously, and the U-shaped frame 6 drives the rotating shaft 2 to rotate at one end of the furnace body 1, thereby driving the sealing door 3 to open.

[0037] When the sealing door 3 is opened, the pull rod 10 drives one end of the push rod 8 to swing, so that the push rod 8 rotates with the end connected to the inner wall of the furnace body 1 as the fulcrum. At the same time, the material rack 4 is pushed to move under the cooperation of the slider 14 and the slide groove 13 by the cooperation of the push column 9 and the push groove 7, so that it extends to the outside of the furnace body 1. At this time, the workpiece to be processed can be placed inside the material rack 4, which makes it convenient for the operator to pick up and put down the workpiece. There is no need to manually take out and put in the material rack 4, and there is no need to add additional drive equipment, which is beneficial to practical application and operation.

[0038] After the workpiece is placed, the sealing door 3 can be closed. By working simultaneously with the two cylinders 5, the rotating shaft 2 and the sealing door 3 rotate in opposite directions. At the same time, the pulling rod 10 drives one end of the pushing rod 8 to swing in the opposite direction. With the cooperation between the pushing column 9 and the pushing groove 7, the material rack 4 is pushed to move in the opposite direction under the cooperation between the slider 14 and the sliding groove 13, so that it is retracted into the interior of the furnace body 1.

[0039] At this point, the workpiece can be processed by controlling the heating rod 12.

[0040] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
