Technical Field

[0001] This utility model specifically relates to the field of brazing furnace technology, and more specifically to a brazing furnace telescopic rotating door. Background Technology

[0002] A brazing furnace is a device used for brazing and bright heat treatment of metals. It is mainly used in the steel and metallurgical industries; for filter and refrigeration parts in the automotive industry, and in the aerospace industry. It can also be used for brazing and bright heat treatment of stainless steel, carbon steel, brass, and copper parts in the refrigerator, air conditioner, electronics, microwave magnetron, and other industries. It is suitable for mass production of small and medium-sized stainless steel parts, such as tableware, knives, and hardware, such as bright quenching and tempering of martensitic stainless steel and bright annealing of austenitic stainless steel.

[0003] Currently, the furnace lid of a brazing furnace is generally opened and closed by flipping. That is, the lid is connected to the furnace body through a hinge structure, and the opening and closing is operated by flipping. However, this process requires a certain amount of space, that is, the top space needs to be sufficient. If the top space is relatively small, this structure is not suitable, so it has certain limitations. To address this, we propose a telescopic rotating door for brazing furnaces to solve the above problems. Utility Model Content

[0004] The purpose of this utility model is to provide a telescopic rotating door for a brazing furnace. The overall structure is relatively simple and easy to operate. It can open the furnace cover when there is insufficient space at the top, thus enabling the device to operate normally in a limited space; thereby solving the technical problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A telescopic rotating door for a brazing furnace includes a brazing furnace body, and a telescopic mechanism is installed on one side of the brazing furnace body; The brazing furnace body includes a furnace body, and a furnace cover is installed on the top of the furnace body.

[0008] As a further technical solution of this utility model, a limiting tooth is provided at the top inner side of the furnace body. The number of limiting teeth is several. The limiting teeth are evenly distributed on the inner side of the furnace body. The limiting teeth occupy half of the inner side of the furnace body. A limiting block is fixedly installed on the other half of the inner side of the furnace body, and the limiting block has a semi-circular structure.

[0009] As a further technical solution of this utility model, an external thread is provided on the top of the outer side of the furnace body, and an internal thread is provided on the inner side of the furnace cover at the position corresponding to the external thread.

Detailed Implementation

[0020] 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.

[0021] Please see Figure 1-6 In this embodiment of the present invention, a brazing furnace telescopic rotating door includes a brazing furnace body 1, and a telescopic mechanism 2 is installed on one side of the brazing furnace body 1. The brazing furnace body 1 includes a furnace body 11, and a furnace cover 12 is installed on the top of the furnace body 11. A connecting plate 13 is fixedly installed at the center of the top of the furnace cover 12, and a connecting seat 14 is fixedly connected to the end of the connecting plate 13 away from the furnace cover 12. A mounting bracket 15 is fixedly installed on the side of the furnace body 11, and a hydraulic rod 16 is connected to the top of the mounting bracket 15 through a rotating shaft. The top of the hydraulic rod 16 is connected to a connecting plate 17 through a rotating shaft.

[0022] In this example, the telescopic mechanism 2 includes a hydraulic cylinder 21 at its bottom end. A hydraulic cylinder mounting seat 22 is fixedly installed at the top end of the hydraulic cylinder 21, and a connecting shaft 23 is connected to the top end of the hydraulic cylinder mounting seat 22 and the hydraulic cylinder 21. Two sets of bearings 24 are symmetrically installed on the side of the connecting shaft 23, and the bearings 24 are welded to the side of the furnace body 11 through a bracket. By adopting the above technical solution, the hydraulic cylinder 21 of the telescopic mechanism 2 can drive the connecting shaft 23 at its top to extend and retract during use. At this time, the hydraulic cylinder mounting base 22 connected to the connecting shaft 23 will perform a synchronous lifting and lowering process. During this process, the connecting plate 13 connected to the hydraulic cylinder mounting base 22 will move up and down, ultimately realizing the lifting and lowering of the furnace cover 12.

[0023] In this example, the bottom end of the connecting seat 14 is fixedly connected to the top end of the connecting shaft 23, and the side of the connecting shaft 23 is fixedly connected to the connecting plate 17. By adopting the above technical solution, the side of the connecting shaft 23 is fixedly connected to the connecting plate 17. That is, when the hydraulic rod 16 is raised and lowered, it will drive the connecting plate 17 to rotate within a certain range at the position of the connecting shaft 23. Since the two are fixedly connected, the connecting shaft 23 will be driven to rotate synchronously. At the same time, combined with the driving process of the telescopic mechanism 2, the furnace cover 12 will rotate synchronously during the rising process, realizing the opening process of the furnace cover 12.

[0024] In this example, a limiting tooth 111 is provided on the inner top of the furnace body 11. There are several limiting teeth 111, which are evenly distributed on the inner side of the furnace body 11. The limiting teeth 111 occupy half of the inner side of the furnace body 11. A limiting block 112 is fixedly installed on the other half of the inner side of the furnace body 11, and the limiting block 112 has a semi-circular structure.

[0025] In this example, the outer top of the furnace body 11 is provided with an external thread 113, and the inner side of the furnace cover 12 is provided with an internal thread at the position corresponding to the external thread 113. The furnace cover 12 is fixedly installed with a snap-fit ​​tooth 121 inside. The snap-fit ​​tooth 121 is the same size and shape as the limiting tooth 111, and the snap-fit ​​tooth 121 occupies one-quarter of the position of the furnace cover 12. The snap-fit ​​tooth 121 is located inside the internal thread.

[0026] In this example, a stepper motor 122 is mounted at the top center of the furnace cover 12 via a mounting bracket 15, and the output end of the stepper motor 122 is connected to the furnace cover 12.

[0027] By adopting the above technical solution, when the furnace cover 12 is closed, the snap-fit ​​teeth 121 located inside the furnace cover 12 are aligned with the position of the limiting teeth 11 and descend through the telescopic mechanism 2. At this time, the snap-fit ​​teeth 121 are located at the bottom of the limiting teeth 111. At this time, the stepper motor 122 is started to rotate between half a turn and one turn, and the snap-fit ​​teeth 121 are located at the bottom of the limiting block 112, realizing the limiting process. On the other hand, the sealing process between the furnace cover 12 and the furnace body 11 is further realized through the external thread 113 and the internal thread on the inner side of the furnace cover 12. Furthermore, the furnace cover 12 is openable by first rotating it in the opposite direction by the same angle via the stepper motor 122, and then activating the telescopic mechanism 2 to raise it, thus completing the unlocking process.

[0028] The working principle of this utility model is as follows: When in use, firstly, when opening, the hydraulic cylinder 21 of the telescopic mechanism 2 can drive the connecting shaft 23 at the top to rise. At this time, the hydraulic cylinder mounting seat 22 connected to the connecting shaft 23 will rise synchronously. During this process, the connecting plate 13 connected to the hydraulic cylinder mounting seat 22 will move upward, and finally realize the rising process of the furnace cover 12. At the same time, the side of the connecting shaft 23 is fixedly connected to the connecting plate 17. That is, when the hydraulic rod 16 rises, it will drive the connecting plate 17 to rotate within a certain range at the position of the connecting shaft 23. Since the two are fixedly connected, the connecting shaft 23 will rotate synchronously. Combined with the driving process of the telescopic mechanism 2, the furnace cover 12 will rotate synchronously during the rising process, thus realizing the opening process of the furnace cover 12. Conversely, during the closing process of the furnace cover 12, the operation steps are reversed. Simply retract the hydraulic rod 16 first, and then retract the hydraulic cylinder 21 of the telescopic mechanism 2 to complete the closing process of the furnace cover 12. The whole structure is relatively simple and easy to operate. It can open the furnace cover 12 when there is insufficient space at the top, and realize the normal operation of the device in a limited space.

[0029] During the opening and closing of the furnace cover, firstly, when the furnace cover 12 is closed, the locking teeth 121 located inside the furnace cover 12 are aligned with the position of the limiting teeth 11 and descend through the telescopic mechanism 2. At this time, the locking teeth 121 are located at the bottom of the limiting teeth 111. At this time, the stepper motor 122 is started to rotate between half a turn and one turn, and the locking teeth 121 are located at the bottom of the limiting block 112, realizing the limiting process. On the other hand, the sealing process between the furnace cover 12 and the furnace body 11 is further realized through the external thread 113 and the internal thread on the inner side of the furnace cover 12. Furthermore, the furnace cover 12 is openable by first rotating it in the opposite direction by the same angle via the stepper motor 122, and then activating the telescopic mechanism 2 to raise it, thus completing the unlocking process.
