Description

Technical Field

[0001] This utility model relates to the field of martensitic steel processing, specifically a multi-stage continuous heat treatment device for high-hardness martensitic steel. Background Technology

[0002] Multi-stage continuous heat treatment of high-hardness martensitic steels (such as tool steel, mold steel, bearing steel, high-strength structural steel, etc.) is an efficient, stable, and advanced process suitable for mass production. It integrates multiple key processes such as preheating, austenitization, quenching, cryogenic treatment, and multi-stage tempering into a continuous production line to ensure consistent product performance and high quality. The process includes feeding and conveying, preheating stage, austenitization heating stage, quenching and cooling stage, cryogenic treatment stage, cleaning and drying stage, multi-stage tempering stage, and post-treatment and inspection.

[0003] However, in the existing multi-stage continuous heat treatment equipment for hardness martensitic steel, during the feeding and conveying stage, workers usually need to manually place several raw materials on the conveyor belt and then separate them one by one to ensure that the raw materials are heated evenly. Due to the lack of a mechanism to separate several raw materials together, workers need to waste a lot of time placing the raw materials in this process, which is not convenient. Utility Model Content

[0004] This utility model aims to provide a multi-stage continuous heat treatment device for high-hardness martensitic steel, mainly to solve the technical problem in the existing technology that the lack of a mechanism to separate several raw materials together results in workers wasting a lot of time to place the raw materials, which is not convenient.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0006] A multi-stage continuous heat treatment device for high-hardness martensitic steel includes a heat treatment equipment body. Two fixed blocks are fixedly connected to a conveyor platform on the heat treatment equipment body. A rotating rod is rotatably connected between the two fixed blocks. One end of the rotating rod passes through the front side of one of the fixed blocks. A limiting block is fixedly connected to the outer wall of the rotating rod near the side of one of the fixed blocks. The device also includes a flipping mechanism, a vertical embedding mechanism, a positioning component, a horizontal embedding mechanism, an elastic locking mechanism, and a limiting component. The flipping mechanism is located outside the rotating rod. The vertical embedding mechanism is located inside the flipping mechanism. Several positioning components are provided, all located on one side of the vertical embedding mechanism, and arranged in a linear array at equal intervals. The horizontal embedding mechanism is movably located on one side of the flipping mechanism, and one side of the horizontal embedding mechanism passes through the flipping mechanism. The elastic locking mechanism is movably located on one side of the horizontal embedding mechanism, and one end of the elastic locking mechanism passes through one side of the horizontal embedding mechanism and is inserted into the positioning component. The limiting component is movably located on the front side of one of the fixed blocks, and the inside of the limiting component is inserted into the limiting block for restriction.

[0007] The working principle and beneficial effects of this utility model:

[0008] 1. Working Principle: When the limiting component is inserted into the limiting block, it restricts the rotation angle of the rotating rod, thereby limiting the position of the flipping mechanism. When the limiting component separates from the limiting block, it releases the restriction on the rotating rod, allowing the rotating rod to drive the flipping mechanism to rotate. By pulling the elastic locking mechanism, the elastic locking mechanism is separated from a positioning component, releasing the restriction on the horizontal embedding mechanism, allowing the horizontal embedding mechanism to slide up and down on one side of the vertical embedding mechanism. This can be adjusted according to the specifications of the raw materials. After adjustment, the elastic locking mechanism is embedded into the corresponding positioning component, thereby re-restricting the horizontal embedding mechanism. Rotating the flipping mechanism counterclockwise allows the flipping mechanism to drive the vertical and horizontal embedding mechanisms to block the raw materials on the conveyor belt in the heat treatment equipment body. Compared with existing technologies, this eliminates the need for manual separation of several raw materials, saving material placement time and improving raw material output efficiency.

[0009] 2. Beneficial effects:

[0010] (1) The moving rod can be pulled out of the positioning hole by the tension spring, thereby releasing the restriction of the moving plate. With the guide rod, the position of the two moving plates can be moved vertically, so as to adjust according to the specifications of the raw materials. After the adjustment is completed, the moving rod is inserted into the corresponding positioning hole with the tension spring, so as to restrict the position of the moving plate again. When the rotating frame is rotated counterclockwise, the first guide plate and the second guide plate can block the raw materials on the conveyor belt in the heat treatment equipment body. Compared with the existing technology, it is not necessary for the staff to manually separate several raw materials, thereby saving the raw material placement time and improving the raw material output efficiency. In addition, the moving block slides on the limiting rod. When the moving block drives the limiting groove to be inserted into the limiting block, the angle of the rotating rod is fixed. When the moving block drives the limiting groove to separate from the limiting block, the restriction on the rotating rod is released, so that the rotating rod can drive the rotating frame to rotate.

[0011] Preferably, the flipping mechanism includes a rotating frame, the bottom end of which is fixedly connected to the middle of the rotating rod; this facilitates counterclockwise rotation of the frame, enabling the rotating frame to drive the vertical embedding mechanism and the horizontal embedding mechanism to separate the raw materials placed on the conveyor belt in the heat treatment equipment body.

[0012] Preferably, the vertical embedding mechanism includes a vertical plate and a first guide plate. The top and bottom ends of the vertical plate are fixedly connected to the top and bottom ends of the inside of the flipping mechanism, respectively. The first guide plate is fixedly connected to one side of the vertical plate. The top and bottom ends of the vertical plate are fixedly connected to the top and bottom ends of the inside of the rotating frame. When the rotating frame is rotated counterclockwise, it moves closer to the raw material on the conveyor belt. At this time, the first guide plate moves closer to the middle of the two sets of raw materials and blocks the two sets of raw materials on both sides of the vertical plate.

[0013] Preferably, the positioning element includes a positioning hole, which is opened on one side of the vertical plate. By setting a number of positioning holes, it is convenient that one end of the elastic snap-fit ​​mechanism is located inside a positioning hole in the initial state, thereby restricting and fixing the position of the transverse embedding mechanism.

[0014] Preferably, the transverse embedding mechanism includes a movable plate and a second guide plate. Connecting plates are fixedly connected to the top and bottom of one side of the flipping mechanism. Two guide rods are fixedly connected between the two connecting plates. Two movable plates are provided, each slidably connected to the outside of the two guide rods. Two second guide plates are fixedly connected to the sides of one side of the two movable plates near the vertical embedding mechanism. Connecting plates are fixedly connected to the top and bottom of one side of the rotating frame. Pulling the support plate away from the rotating frame causes the support plate to separate the movable rod from the positioning hole. Simultaneously, the support plate causes the tension spring to stretch, thereby releasing the restriction on the movable plate. The two movable plates slide up and down on one side of the rotating frame, allowing the movable plates to slide on the guide rods, thus allowing adjustment according to the specifications of the raw materials.

[0015] Preferably, the elastic locking mechanism includes a moving rod, a support plate, and a tension spring. The outer wall of the moving rod slides through both sides of the moving plate. One end of the moving rod is fixedly connected to the support plate, and a tension spring is sleeved on the outer side of the moving rod. One end of the tension spring is fixedly connected to one side of the support plate, and the other end is fixedly connected to one side of the moving plate.

[0016] Preferably, the limiting component includes a limiting rod, a limiting plate, a movable block, a guide hole, and a limiting groove. One end of the limiting rod is fixedly connected to the front side of a fixed block, and the limiting plate is fixedly connected to the other end of the limiting rod. The movable block is slidably connected to the outer wall of the limiting rod. The front and rear sides of the movable block have the same guide hole, and the front and rear sides of the movable block have the same limiting groove communicating with the guide hole. The movable block is sleeved on the outer wall of the rotating rod through the guide hole, and the inner wall of the limiting groove is adapted to the outer wall of the limiting block. Moving the movable block in front of a limiting block allows it to slide on the limiting rod. When the movable block causes the limiting groove to insert into the limiting block, and simultaneously causes the guide hole to sleeve onto the rotating rod, the angle of the rotating rod is fixed. When the movable block causes the limiting groove to separate from the limiting block, and simultaneously causes the guide hole to separate from the outer side of the rotating rod, the restriction on the rotating rod is released, allowing the rotating rod to drive the rotating frame to rotate.

[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 1-4As shown, a multi-stage continuous heat treatment device for high-hardness martensitic steel includes a heat treatment equipment body 1. Two fixed blocks 2 are fixedly connected to the conveyor platform on the heat treatment equipment body 1. A rotating rod 3 is rotatably connected between the two fixed blocks 2. One end of the rotating rod 3 passes through the front side of one of the fixed blocks 2. A limiting block 20 is fixedly connected to the outer wall of the rotating rod 3 near one of the fixed blocks 2. The device also includes a flipping mechanism, a vertical embedding mechanism, a positioning component, a horizontal embedding mechanism, an elastic locking mechanism, and a limiting component. The flipping mechanism is located outside the rotating rod 3 and includes a rotating frame 4. The bottom end of the rotating frame 4 is fixedly connected to the middle of the rotating rod 3. The vertical embedding mechanism is located inside the flipping mechanism and includes a vertical plate 5 and a first guide plate 6. The top and bottom ends of the vertical plate 5 are respectively fixedly connected to... The top and bottom of the vertical plate 5 are fixedly connected to the vertical plate 5. A first guide plate 6 is fixedly connected to one side of the vertical plate 5. Several positioning components are provided, all of which are located on one side of the vertical embedding mechanism. The positioning components are arranged in a linear array at equal intervals. Each positioning component includes a positioning hole 7, which is opened on one side of the vertical plate 5. The horizontal embedding mechanism is movably located on one side of the vertical plate 5 and passes through the vertical plate 5. The horizontal embedding mechanism includes a moving plate 10 and a second guide plate 14. Connecting plates 8 are fixedly connected to the top and bottom of one side of the vertical plate 5. Two guide rods 9 are fixedly connected between the two connecting plates 8. Two moving plates 10 are provided, and both moving plates 10 are slidably connected to the outside of the two guide rods 9. One side of the two moving plates 10 is close to the vertical embedding mechanism. Two second guide plates 14 are fixedly connected to each side. An elastic snap-fit ​​mechanism is movably set on one side of the transverse embedding mechanism. One end of the elastic snap-fit ​​mechanism passes through one side of the transverse embedding mechanism, and the other end of the elastic snap-fit ​​mechanism is inserted into the positioning member. The elastic snap-fit ​​mechanism includes a moving rod 11, a support plate 12, and a tension spring 13. The outer wall of the moving rod 11 slides through both sides of the moving plate 10. One end of the moving rod 11 is fixedly connected to the support plate 12, and a tension spring 13 is sleeved on the outer side of the moving rod 11. One end of the tension spring 13 is fixedly connected to one side of the support plate 12, and the other end is fixedly connected to one side of the moving plate 10. The raw materials are placed vertically and divided into two groups on the conveyor belt in the body 1 of the heat treatment equipment. Then, the support plate 12 is pulled away from the rotating frame 4, so that the support plate 12 moves away from the rotating frame 4. The moving rod 11 separates from the positioning hole 7, and simultaneously the support plate 12 drives the tension spring 13 to stretch, thereby releasing the restriction on the moving plate 10. The two moving plates 10 slide up and down on one side of the rotating frame 4, allowing them to slide on the guide rod 9. This allows for adjustment according to the specifications of the raw materials. After adjustment, the moving rod 11 is aligned with one of the positioning holes 7. The support plate 12 is then released. Due to the reaction force of the tension spring 13, the support plate 12 moves, causing the moving rod 11 to re-embed into the corresponding positioning hole 7, thus re-restricting the position of the moving plate 10. The rotating frame 4 is then rotated counterclockwise, causing it to move closer to the raw materials on the conveyor belt. At this time, the first guide plate 6 moves closer to the middle of the two sets of raw materials.The two sets of raw materials are respectively blocked on both sides of the vertical plate 5, while the two sets of second guide plates 14 move closer to the middle of the adjacent raw materials, so that several raw materials are blocked on the outside of the two sets of second guide plates 14. This facilitates the blocking of raw materials on the conveyor belt in the heat treatment equipment body 1. Compared with the existing technology, it eliminates the need for workers to manually separate and place several raw materials, thereby saving raw material placement time and improving raw material output efficiency.

[0024] A limiting component is movably disposed on the front side of a fixed block 2, and the limiting component is inserted into the limiting block 20 for constraint. The limiting component includes a limiting rod 15, a limiting plate 16, a movable block 17, a guide hole 18, and a limiting groove 19. One end of the limiting rod 15 is fixedly connected to the front side of a fixed block 2, and the limiting plate 16 is fixedly connected to the other end of the limiting rod 15. The movable block 17 is slidably connected to the outer wall of the limiting rod 15. The front and rear sides of the movable block 17 have the same guide hole 18, and the front and rear sides of the movable block 17 have the same limiting groove 19 communicating with the guide hole 18. The movable block 17 is sleeved on the rotating block 2 through the guide hole 18. The outer wall of rod 3 and the inner wall of limiting groove 19 are adapted to the outer wall of limiting block 20; the moving block 17 is moved to the front of a limiting block 20, so that the moving block 17 slides on the limiting rod 15. When the moving block 17 drives the limiting groove 19 to be inserted into the limiting block 20, the moving block 17 drives the guide hole 18 to be sleeved on the rotating rod 3, thereby fixing the angle of the rotating rod 3. When the moving block 17 drives the limiting groove 19 to separate from the limiting block 20, the moving block 17 drives the guide hole 18 to separate from the outside of the rotating rod 3, thereby releasing the restriction on the rotating rod 3, so that the rotating rod 3 can drive the rotating frame 4 to rotate.

[0025] As described above, the specific implementation of this utility model is as follows: The raw materials are placed vertically and divided into two groups on the conveyor belt in the body 1 of the heat treatment equipment. Then, the support plate 12 is pulled away from the rotating frame 4, causing the support plate 12 to drive the moving rod 11 to separate from the positioning hole 7. At the same time, the support plate 12 drives the tension spring 13 to stretch, thereby releasing the restriction on the moving plate 10. The two moving plates 10 slide up and down on one side of the rotating frame 4, so that the moving plate 10 slides on the guide rod 9. This can be adjusted according to the specifications of the raw materials. After the adjustment is completed, the moving rod 11 is aligned with one of the positioning holes 7. The support plate 12 is released. Due to the reaction force of the tension spring 13, the support plate 12 is moved, so that the support plate 12 drives the moving rod 11 to re-embed into the corresponding positioning hole 7, thereby re-restricting the position of the moving plate 10. The rotating frame 4 is rotated counterclockwise, so that the rotating frame 4 moves closer to the raw materials on the conveyor belt. At this time, the first guide plate 6 and the two groups The raw materials are placed close together in the middle, and the two sets of raw materials are respectively blocked on both sides of the vertical plate 5. The two sets of second guide plates 14 are placed close to the middle of the adjacent raw materials, so that several raw materials are blocked on the outside of the two sets of second guide plates 14. This makes it easier to block the raw materials on the conveyor belt in the heat treatment equipment body 1 together. Compared with the existing technology, it is not necessary for the staff to manually separate several raw materials, thus saving the raw material placement time and improving the raw material output efficiency. In addition, the moving block 17 is moved in front of a limiting block 20, so that the moving block 17 slides on the limiting rod 15. When the moving block 17 drives the limiting groove 19 to be inserted into the limiting block 20, the moving block 17 drives the guide hole 18 to be sleeved on the rotating rod 3, thus fixing the angle of the rotating rod 3. When the moving block 17 drives the limiting groove 19 to separate from the limiting block 20, the moving block 17 drives the guide hole 18 to separate from the outside of the rotating rod 3, thus releasing the restriction on the rotating rod 3, so that the rotating rod 3 can drive the rotating frame 4 to rotate.

[0026] The above descriptions are merely embodiments of this utility model, and common knowledge regarding specific structures and characteristics is not elaborated upon here. It should be noted that those skilled in the art can make various modifications and improvements without departing from the structure of this utility model, and these should also be considered within the scope of protection of this utility model.
