Description

Technical Field

[0001] This utility model belongs to the technical field of stainless steel gasket processing equipment, specifically a heat treatment device for processing stainless steel gaskets. Background Technology

[0002] Stainless steel washers are a common type of mechanical part, usually in the shape of a ring, used to distribute the pressure under bolts or nuts, protect the surface of connected parts from damage, prevent loosening, and improve the reliability and sealing of the connection. They are widely used in many fields such as machinery manufacturing, automotive industry, construction engineering, and electronic equipment.

[0003] A search revealed an automatic heat treatment device for metal gaskets, publication number CN212504996U. This device addresses the common problem of separate clamps and heating chambers, which can easily lead to loss or forgetting of the clamps during prolonged use, making it impossible to retrieve heated metal gaskets. The proposed solution uses a moving rail, moving wheels, a placement plate, and a support rod. The clamps are placed in the placement plate, and during operation, the placement plate is moved out via the moving wheels along the moving groove of the moving rail, allowing the clamps to be removed for use. When not in use, the clamps are placed on the placement plate and pushed into the bottom of the heating chamber, preventing obstruction of operation. This design offers the advantage of preventing loss or forgetting of the clamps. However, in practical use, it still has shortcomings. Because stainless steel gaskets need to be placed inside the furnace for heat treatment, and the furnace has a certain depth, when the stainless steel gasket is deep inside, it obstructs the operator's view, making it inconvenient for the operator to retrieve the gasket. Therefore, improvements are needed. Utility Model Content

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] like Figures 1 to 7 As shown, this utility model provides a heat treatment device for processing stainless steel washers, including a heat treatment chamber 1. Support legs 2 are fixedly installed at the four corners of the bottom of the heat treatment chamber 1. A chamber door 3 is hinged to the middle of the front end of the heat treatment chamber 1. A furnace liner 4 is fixedly fitted inside the heat treatment chamber 1. A placement plate 5 is movably fitted to the bottom of the furnace liner 4. A placement groove 6 is formed at the top of the placement plate 5. A connecting rod 7 is fixedly installed on the front side of the right end of the placement plate 5. The right end of the connecting rod 7 passes through the furnace liner 4 and the heat treatment chamber 1 and extends to the outside of the heat treatment chamber 1. The outer surface of the connecting rod 7 is movably connected to the outer surface of the chamber door 3. A toothed plate 8 is fixedly fitted to the right side of the outer surface of the connecting rod 7. The outer surface of the toothed plate 8 is movably connected to the outer surface of the heat treatment chamber 1. A T-shaped block 9 is movably fitted to the front end of the toothed plate 8. The outer surface of the T-shaped block 9 is fixedly connected to the outer surface of the heat treatment chamber 1. A drive motor 10 is fixedly installed on the front side of the end, and a drive shaft 11 is fixedly sleeved on the other end of the output shaft of the drive motor 10. A gear 12 is fixedly sleeved on the outer surface of the drive shaft 11. The left end of the gear 12 is movably connected to the right end of the heat treatment box 1, and the outer surface of the gear 12 meshes with the outer surface of the toothed plate 8. When the drive motor 10 is started, the drive shaft 11 will drive the gear 12 to rotate. Since the gear 12 and the toothed plate 8 mesh with each other, the toothed plate 8 will move along the outer surface of the T-block 9 as the gear 12 rotates. This causes the connecting rod 7, which is fixedly connected to the toothed plate 8, to move along with the placement plate 5, thereby pushing the placement plate 5 out of the furnace chamber 4. The presence of the placement groove 6 can ensure the stability of the stainless steel gasket placement. In this way, the convenience of removing the stainless steel gasket can be improved through the cooperation of various mechanisms.

[0024] The placement plate 5 has limiting grooves 13 at its left and right ends, and a limiting block 14 is movably sleeved at the front end of the limiting groove 13. The outer surface of the limiting block 14 is fixedly connected to the inner wall of the furnace 4. The inner surface of the limiting groove 13 and the outer surface of the limiting block 14 are both smooth, which ensures that the placement plate 5 will not get stuck when it moves along the outer surface of the limiting block 14. At the same time, the cooperation between the limiting groove 13 and the limiting block 14 will restrict the movement of the placement plate 5, thereby preventing the placement plate 5 from separating from the furnace 4.

[0025] The placement groove 6 has a circular block 15 movably fitted inside, and a circular rod 16 is fixedly installed at the bottom end of the circular block 15. The bottom end of the circular rod 16 passes through the placement plate 5 and extends to the outside of the placement plate 5. When the circular rod 16 moves along the inner surface of the placement plate 5, the circular block 15 fixedly connected to the circular rod 16 will move along with it, thereby pushing the stainless steel washer out of the placement groove 6, making it convenient for the operator to use pliers to pick up the stainless steel washer.

[0026] The bottom of the outer surface of the round rod 16 is fixedly sleeved with a base plate 17. The top left and right sides of the base plate 17 are respectively fixedly installed with first springs 18. The other end of the first spring 18 is fixedly connected to the bottom end of the placement plate 5. When the first spring 18 is in a stretched state, when the base plate 17 is no longer blocked, under the restoring action of the first spring 18, the base plate 17 will be forced to move towards the placement plate 5, so that the round rod 16 fixedly sleeved with the base plate 17 moves upward together.

[0027] The base plate 17 has a slot 19 in the middle of its front end, and a retaining plate 20 is movably sleeved inside the slot 19. The presence of the slot 19 and the retaining plate 20 will lock the position of the base plate 17, thereby ensuring that the first spring 18 can remain in a stretched state.

[0028] The card plate 20 is internally fitted with a limiting plate 21. The top end of the limiting plate 21 is fixedly connected to the bottom end of the placement plate 5. The limiting plate 21 is internally fitted with a limiting rod 22. The outer surface of the limiting rod 22 is fixedly fitted to the inner surface of the card plate 20. A second spring 23 located outside the limiting rod 22 is fixedly installed at the bottom of the rear end of the limiting plate 21. The other end of the second spring 23 is fixedly connected to the inner surface of the card plate 20. When the card plate 20 is pulled, it will move along the outer surface of the limiting plate 21 and compress the second spring 23. Under the restoring action of the second spring 23, when the card plate 20 is released, it will return to its original position. At the same time, the presence of the limiting rod 22 is used to assist in limiting the card plate 20.

[0029] The first fixing block 24 is fixedly installed in the middle of the right end of the door 3. The fixing bolt 25 is threaded inside the first fixing block 24. The second fixing block 26 is threaded on the rear side of the outer surface of the fixing bolt 25. The outer surface of the second fixing block 26 is fixedly connected to the outer surface of the heat treatment box 1. When the fixing bolt 25 is rotated, the fixing bolt 25 will rotate. Since the fixing bolt 25 and the second fixing block 26 are threaded together, the fixing bolt 25 will separate from the second fixing block 26 as the fixing bolt 25 rotates. At this time, pulling the fixing bolt 25 can open the door 3.

[0030] Working principle and usage process of this utility model:

[0031] After the stainless steel gasket has been heat-treated, the operator rotates the fixing bolt 25 to separate the fixing bolt 25 from the second fixing block 26, then opens the box door 3, and then starts the drive motor 10, causing the drive shaft 11 to drive the gear 12 to rotate. Since the gear 12 and the toothed plate 8 mesh with each other, as the gear 12 rotates, the toothed plate 8 will move along the outer surface of the T-block 9 through the connecting rod 7, carrying the placement plate 5 towards the outside of the furnace chamber 4, thereby pushing the placement plate 5 out of the furnace chamber 4, so that the stainless steel gasket can be removed from the inside of the furnace chamber 4, thus improving the convenience of removing the stainless steel gasket.

[0032] Before the operator uses pliers to pick up the stainless steel washer, pull the clamping plate 20, causing the clamping plate 20 to move along the outer surface of the limiting plate 21 and compress the second spring 23 until the clamping plate 20 and the clamping groove 19 separate. Since the first spring 18 is in a stretched state, under the restoring action of the first spring 18, the base plate 17 will move upward with the round rod 16 and the round block 15, thereby pushing the stainless steel washer out of the placement groove 6, thus not obstructing the operator from picking up the stainless steel washer with pliers.
