Description

Technical Field

[0001] This utility model relates to the field of metal plate processing technology, specifically to a heat treatment mechanism for metal plate processing. Background Technology

[0002] In modern industrial production, metal sheets are widely used. Heat treatment, as a key step in the processing of metal sheets, can significantly improve the microstructure and properties of metal materials, and enhance their strength, hardness, toughness, and corrosion resistance, thus meeting the needs of different industrial applications.

[0003] Traditional heat treatment facilities for metal sheet processing mostly use a single-batch processing method. After a batch of metal sheets has been heat treated, the sheets need to be manually removed and new sheets to be processed need to be placed in. The whole process is cumbersome, inefficient, and affects the progress of heat treatment for metal sheet processing. Utility Model Content

[0004] In view of the shortcomings of the existing technology, this utility model provides a heat treatment mechanism for metal sheet processing, which solves the problem of low efficiency in traditional metal sheet processing heat treatment.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a heat treatment mechanism for metal sheet processing, comprising a heating frame mounted on a base, door panels slidably connected to both sides of the top of the heating frame via through slots, a through slot on the side of the base, a movable plate slidably connected inside the through slot, L-plates fixedly connected to both sides of the top of the movable plate, a placement plate fixedly connected to one end of each of the two L-plates, pulleys provided on both sides of the bottom of the movable plate, a support frame fixedly connected to the top of the two door panels, an electric telescopic rod mounted on the top of the heating frame, the telescopic end of the electric telescopic rod fixedly connected to the bottom of the support frame, and the tops of the two door panels fixedly connected to both sides of the bottom of the support frame.

[0006] Preferably, the bottom of the door panel has a U-shaped opening that cooperates with the L-plate, the top of the U-shaped opening has a groove, an abutment plate is slidably connected in the groove, and a spring is fixedly connected between the top of the abutment plate and the top of the groove cavity.

[0007] Preferably, a limiting rod is fixedly connected to the top of the L-plate, and a limiting groove is provided at the bottom of the contact plate to cooperate with the limiting rod.

[0008] Preferably, the bottom of the placement plate is provided with a plurality of ball bearings.

[0009] Preferably, an electric heating block is installed at the top of the inner cavity of the heating frame.

[0010] This utility model provides a heat treatment mechanism for processing metal plates. It has the following beneficial effects:

[0011] This invention enables alternating heat treatment of metal plates by setting two placement plates. While metal plates on one placement plate are being heat treated, the next batch of plates to be treated can be prepared on the other placement plate. The process can be switched after the heat treatment of one batch of metal plates is completed, reducing equipment downtime and improving production efficiency to a certain extent. The cooperation between the door plate, L-plate, spring, contact plate and limit rod prevents heat loss from the furnace body to a certain extent, and the placement plate can be fixed when the door plate is closed.

[0016] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0017] Please see Figure 1-3 This utility model provides a technical solution: a heat treatment mechanism for metal sheet processing, including a heating frame 2 mounted on a base 1. Door panels 3 are slidably connected to both sides of the top of the heating frame 2 via through slots. A through slot 4 is provided on the side of the base 1, and a movable plate 5 is slidably connected inside the through slot 4. L-plates 6 are fixedly connected to both sides of the top of the movable plate 5, and placement plates 7 are fixedly connected to opposite ends of the two L-plates 6. Rollers 8 are provided on both sides of the bottom of the movable plate 5. A support frame 9 is fixedly connected to the top of both door panels 3. An electric telescopic rod 10 is installed on the top of the heating frame 2, and the telescopic end of the electric telescopic rod 10 is fixedly connected to the bottom of the support frame 9. The tops of the two door panels 3 are respectively fixedly connected to both sides of the bottom of the support frame 9.

[0018] Furthermore, in order to prevent heat loss from the furnace body, the bottom of the door panel 3 is provided with a U-shaped opening 11 that cooperates with the L-plate 6. The top of the U-shaped opening 11 is provided with a groove 12. An abutment plate 13 is slidably connected in the groove 12. A spring 14 is fixedly connected between the top of the abutment plate 13 and the top of the inner cavity of the groove 12.

[0019] Furthermore, in order to automatically limit the placement plate 7 during the closing process of the door panel 3, a limit rod 15 is fixedly connected to the top of the L plate 6, and a limit groove 16 is provided at the bottom of the contact plate 13 to cooperate with the limit rod 15.

[0020] To facilitate the movement of the placement plate 7, several ball bearings 17 are provided on the bottom of the placement plate 7.

[0021] An electric heating block 18 is installed at the top of the inner cavity of the heating frame 2. The electric heating block 18 is of type HDO and is powered by an external power source.

[0022] During operation, initially, door panel 3 is in the raised state. The metal plate to be heat-treated is placed on the left placement plate 7. The moving plate 5 is pushed, causing the left L-plate 6 and placement plate 7 to move into the heating frame 2 until they reach the designated position. The electric telescopic rod 10 is then activated, causing door panel 3 to move downwards via the support frame 9. During the descent, L-plate 6 abuts against the contact plate 13, causing the contact plate 13 to move upwards within the groove 12 and compress the spring 14. When door panel 3 is fully closed, L-plate 6 is engaged in the U-shaped opening 11 of door panel 3. The contact plate 13, under the action of the spring 14, is tightly fitted against L-plate 6. Simultaneously, the limiting rod 15 is inserted into the limiting groove 16 to fix L-plate 6. Then, the electric heating block 18 is activated. The metal plates on the placement plate 7 inside the heating frame 2 are heat-treated. During the heat treatment process, the next batch of metal plates to be heat-treated can be placed on the right placement plate 7. After the metal plates on the left placement plate 7 have been heat-treated, the electric telescopic rod 10 is started again to move the door panel 3 upward. Then, the moving plate 5 is pushed in the opposite direction to move the right L plate 6 and the placement plate 7 into the heating frame 2. At the same time, the moving plate 5 will move the left placement plate 7 out of the heating frame 2. After the right placement plate 7 has moved to the designated position inside the heating frame 2, the electric telescopic rod 10 is started to close the door panel 3, and the subsequent heat treatment processing can be carried out. At this time, the heat-treated metal plates on the left placement plate 7 can be transferred, and a new batch of metal plates can be placed on them. This cycle is repeated.
