Description

Technical Field

[0001] This application relates to the technical field of metal heat treatment, and in particular to a metal heat treatment clamp. Background Technology

[0002] Metal heat treatment is a process in which metal workpieces are heated to a suitable temperature in a certain medium, held at that temperature for a certain time, and then cooled at different rates in different media. By changing the microstructure of the surface or interior of the metal material, its properties can be controlled. When parts are heat treated, clamping devices are required. Existing clamping frames generally clamp the metal on both sides using clamping plates. However, this clamping method is a fixed clamping method and is not convenient for clamping metals of different shapes.

[0003] In related technologies, a metal heat treatment clamping frame includes a base and further includes: supports on both sides of the base, a first cylinder mounted on the supports, the telescopic end of the first cylinder being rotatably connected to a U-shaped frame, a positioning plate mounted on the end of the U-shaped frame away from the first cylinder, both ends of the positioning plate being hinged to the ends of a movable plate; adjustment components on both sides of the U-shaped frame and connected to the movable plate; a flipping component on the supports and connected to the U-shaped frame; and a material support component on the base for lifting the metal to be heat treated. This invention uses the material support component to lift the metal to be heat treated, facilitating clamping and fixing. Furthermore, the positioning plate and the adjustable movable plate allow for clamping and fixing metals of different shapes, improving the applicability of the device. Additionally, the device can also flip the metal during heat treatment using the flipping component.

[0004] Although the device improves its applicability by clamping and fixing metals of different shapes using positioning plates and adjustable movable plates, and can also flip metals in heat treatment using flipping components, it still has shortcomings: during use, when clamping metal, the positioning plates cover the metal surface, resulting in insufficient heating of the clamping surface and creating blind spots in the metal heat treatment process. Summary of the Invention

[0005] In order to reduce insufficient heating and reduce blind spots during heat treatment, this application provides a metal heat treatment clamp.

[0006] The metal heat treatment clamp provided in this application adopts the following technical solution:

[0007] A metal heat treatment clamping rack includes a base, with two base boxes fixedly connected to the bottom of the base and a base box fixedly connected to the top of the base. Two sets of support rods are fixedly connected to the top of each base box, and a sliding plate is slidably connected between each set of support rods. A first cylinder is fixedly connected to one side of each of the two sliding plates, and a clamping plate is fixedly connected to the telescopic end of each of the two first cylinders. A set of fixing rods is fixedly connected to one side of each of the two clamping plates, and a set of compression springs is fixedly connected to one end of each set of compression springs. A clamping block is fixedly connected to the top fixed plate of the base box. A lifting device for adjusting the height of the two sliding plates is provided inside the base box. A placement tray is provided on the top of the mounting block, and a rotating device for rotating the placement tray 90 degrees is provided inside the mounting block.

[0008] Preferably, a groove is provided on one side of each of the two sets of support rods, and the two ends of each sliding plate are slidably connected inside the groove of each set of support rods, and a threaded block is fixedly connected to one side of each of the two sliding plates.

[0009] Preferably, the lifting device includes a drive motor, a first sprocket, a second sprocket, a chain, and a threaded rod. The drive motor is fixedly connected to the bottom of the base. The movable end of the drive motor passes through the base and is fixedly connected to the first sprocket and the second sprocket. A chain is meshed with one side of both the first sprocket and the second sprocket. A threaded rod is threadedly connected to the bottom of each of the two threaded blocks.

[0010] Preferably, the bottom ends of both threaded rods are rotatably connected to the inner wall of the support rod through the support rod, and a first sprocket is fixedly connected to the outer surface of one threaded rod, and a second sprocket is fixedly connected to the outer surface of the other threaded rod. One chain is engaged between the two first sprockets, and the other chain is engaged between the two second sprockets.

[0011] Preferably, the rotating device includes a fixed plate, a second cylinder, a push rod, a rotating block, a rotating rod, a fixed tube, a locking rod, and a compression spring. The top of the base box is fixedly connected to the fixed plate, and the second cylinder is fixedly connected to one side of the fixed plate. The telescopic end of the second cylinder passes through the fixed plate and is fixedly connected to the push rod. One end of the push rod is movably connected to the rotating block, and the top of the rotating block is fixedly connected to the rotating rod. The inner wall of the mounting block is fixedly connected to the fixed tube, and the bottom end of the fixed tube is movably connected to the locking rod. A compression spring is fixedly connected between the fixed tube and the locking rod.

[0012] Preferably, the mounting block is hollow inside, and one end of the mounting block has a movable groove, and one end of the push rod is slidably connected inside the movable groove, and the rotating block is located inside the mounting block.

[0013] Preferably, the bottom end of the rotating rod passes through the rotating block and is rotatably connected to the inner wall of the mounting block, and the top end of the rotating rod passes through the mounting block and is fixedly connected to the bottom of the placement tray. The top of the rotating block has four slots, and the bottom end of the locking rod is movably connected to the inside of the slots.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] Two sets of first cylinders drive the clamping plates, and the flexible connection between the fixed rod and the compression spring achieves adaptive clamping of metal workpieces. The compression spring ensures that the clamping force adapts to the effect of thermal expansion and contraction, avoiding workpiece deformation or loosening of the clamp, and also reduces the risk of surface damage through elastic buffering, making it particularly suitable for heat treatment of easily deformable metals.

[0016] The double-threaded rod is synchronously controlled by a drive motor via a sprocket-chain transmission, which in turn moves the sliding plate vertically along the support rod, allowing the workpiece to be detached from the tray for suspended heat treatment. This design solves the problem of uneven heating at the bottom of traditional clamping frames, achieving uniform heating from all directions.

[0017] The second cylinder pushes the rotating block, which, in conjunction with the locking structure of the locking rod and compression spring, enables 90° step-by-step rotation of the placed tray. The mechanical locking design (four slots) ensures precise rotation angles each time, and the secondary fixing of the clamping system allows the unheated surface of the workpiece to be rotated to the heating area, completely eliminating blind spots in heat treatment. The coordinated operation of the lifting and rotating devices (lifting and clamping first, then rotating) ensures operational safety and reduces manual intervention through automation, significantly improving processing efficiency.

[0028] Furthermore, the lifting device includes a drive motor 10, a first sprocket 11, a second sprocket 12, a chain 13, and a threaded rod 14. The drive motor 10 is fixedly connected to the bottom of the base 1. The movable end of the drive motor 10 passes through the base 1 and is fixedly connected to the first sprocket 11 and the second sprocket 12. The chain 13 is meshed with one side of both the first sprocket 11 and the second sprocket 12. A threaded rod 14 is threadedly connected to the bottom of each of the two threaded blocks 15.

[0029] Furthermore, the bottom ends of both threaded rods 14 are rotatably connected to the inner wall of the support rod 4 through the support rod 4, and a first sprocket 11 is fixedly connected to the outer surface of one of the threaded rods 14, and a second sprocket 12 is fixedly connected to the outer surface of the other threaded rod 14. One chain 13 is engaged between the two first sprockets 11, and the other chain 13 is engaged between the two second sprockets 12.

[0030] Furthermore, the rotating device includes a fixed plate 16, a second cylinder 17, a push rod 18, a rotating block 19, a rotating rod 20, a fixed tube 21, a locking rod 22, and a compression spring 23. The top of the base box 3 is fixedly connected to the fixed plate 16, and the second cylinder 17 is fixedly connected to one side of the fixed plate 16. The telescopic end of the second cylinder 17 passes through the fixed plate 16 and is fixedly connected to the push rod 18. One end of the push rod 18 is movably connected to the rotating block 19, and the top of the rotating block 19 is fixedly connected to the rotating rod 20. The inner wall of the mounting block 8 is fixedly connected to the fixed tube 21, and the bottom end of the fixed tube 21 is movably connected to the locking rod 22. A compression spring 23 is fixedly connected between the fixed tube 21 and the locking rod 22.

[0031] Furthermore, the interior of the mounting block 8 is hollow, and one end of the mounting block 8 has a movable groove. One end of the push rod 18 is slidably connected inside the movable groove, and the rotating block 19 is located inside the mounting block 8.

[0032] Furthermore, the bottom end of the rotating rod 20 passes through the rotating block 19 and is rotatably connected to the inner wall of the mounting block 8, and the top end of the rotating rod 20 passes through the mounting block 8 and is fixedly connected to the bottom of the placement tray 9. The top of the rotating block 19 is provided with four slots 24, and the bottom end of the locking rod 22 is movably connected to the inside of the slots 24.

[0033] In use, when heat treatment of metal is required, the metal is first placed on the placement tray 9. Then, two first cylinders 6 are activated, causing their moving ends to move two clamping plates 7 closer to the metal. The clamping plates 7, through the fixed rod 25, drive the clamping blocks 27 to clamp the metal. Then, the drive motor 10 is activated, causing its moving end to rotate the first sprocket 11 and the second sprocket 12. Through the meshing connection between the two chains 13 and the first sprocket 11 and the second sprocket 12, the two threaded rods 14 are rotated. Then, through the meshing connection between the two threaded rods 14 and the two threaded blocks 15, the two threaded blocks 15 drive the two sliding plates 5 to slide upward between the two sets of support rods 4. This allows the two sliding plates 5 to drive the two first cylinders 6, causing the metal to move upward and detach from the placement tray 9, allowing the bottom of the metal to also be heat treated. Simultaneously, the compression spring 2 between the fixed rod 25 and the clamping blocks 27 is utilized. The elasticity of cylinder 6 prevents damage to the metal surface caused by clamping force of clamping block 27, and also prevents insufficient clamping force due to thermal expansion and contraction of the metal. Then, the metal is placed on the placement tray 9 again by lifting device. Then, by activating the second cylinder 17, the extension end of the second cylinder 17 drives the push rod 18 to push into the interior of the mounting block 8, so that one end of the push rod 18 pushes a corner of the rotating block 19, so that the rotating block 19 rotates around the rotating rod 20 and drives the rotating rod 20 to rotate 90 degrees. Thus, the top of the rotating rod 20 drives the placement tray 9 to rotate 90 degrees, so that the metal rotates 90 degrees. Then, while the rotating block 19 is rotating, the locking rod 22 will compress the spring 23, so that the bottom end of the locking rod 22 enters from one slot 24 into the next slot 24. Then, the first cylinder 6 drives the clamping plate 7 to clamp the metal, so that the surface of the metal initially clamped can be heat treated, so that the metal can be completely heat treated.

[0034] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
