Description

Technical Field

[0001] This utility model relates to the field of forging processing technology, and in particular to a forging flipping and clamping device. Background Technology

[0002] Forgings are workpieces with specific shapes, sizes and mechanical properties made by applying external force to metal materials to cause plastic deformation. In essence, they change the internal grain structure of the metal by external force, eliminate casting defects, and make the metal structure denser and the mechanical properties superior, far exceeding those of castings, welded parts and other processed products. Therefore, they are widely used in key components that withstand harsh working conditions such as heavy loads, impacts and high temperatures.

[0003] In order to ensure that the forgings can receive forging forces in multiple directions during forging, and to achieve more complete and uniform metal deformation, thereby fundamentally reducing defects such as segregation, porosity, and coarse grains, the forgings need to be flipped. However, current forging equipment cannot cover all the machined surfaces of the forgings, resulting in some areas being unforgeable. Therefore, it is necessary to flip the forgings so that the target surface faces upwards so that they can be forged. This directly determines the final performance and pass rate of the forgings.

[0004] However, manual turning of forgings also has some drawbacks. During the forging process, the surface of the forging is red-hot, and the operator needs to use tools such as pliers and pry bars to turn over the hot metal chips or the forging body itself, which can easily come into contact with the human body and cause burns. In addition, for heavier forgings, manual turning is slow, which causes the equipment to wait for manual turning frequently, greatly reducing the utilization rate of the equipment. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a forging flipping and clamping device, which aims to improve the problems of potential burns from forgings and slow flipping speed when manually flipping forgings using tools such as pliers and pry bars, thereby reducing the forging rate.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a forging flipping and clamping device, comprising a fixed platform, a support column fixedly connected to the lower surface of the fixed platform, a slider fixedly connected to the lower surface of the support column, a slide rail slidably connected to the inner wall of the slider, a lead screw threadedly connected to the inner wall of the slider, one end of the lead screw being fixedly connected to an output end of a motor, and the other end of the lead screw being rotatably connected to a support frame, and a flipping assembly on the inner wall of the fixed platform; The flipping assembly includes a second motor, the outer wall of which is fixedly connected to the inner wall of the fixed platform. The output end of the second motor is fixedly connected to a housing, the inner wall of which is fixedly connected to a cylinder, the output end of which is fixedly connected to a fixed block, the outer wall of which is rotatably connected to a second connecting rod, the inner wall of which is rotatably connected to a first connecting rod, and the outer wall of the first connecting rod is fixedly connected to a gripper.

[0007] Furthermore, the inner wall of the gripper is threaded with a threaded pin, one end of which is fixedly connected to a knob, and the other end of which is fixedly connected to a connecting block. The outer wall of the connecting block is rotatably connected to a push plate, and the outer wall of the push plate is fixedly connected to a housing. A spring is provided inside the gripper, one end of which is fixedly connected to the inner wall of the housing, and the other end of which is fixedly connected to a connecting disc. A sub-grip block is fixedly connected to the outer wall of the connecting disc.

[0008] Furthermore, the outer wall of the push plate is slidably connected to the inner wall of the gripper, and the connecting disc is slidably connected to the inner wall of the outer casing.

[0009] Furthermore, the sub-clamp block is slidably connected to the inner wall of the clamp.

[0010] Furthermore, the outer wall of the sub-clamp block is slidably connected to the inner wall of the outer shell.

[0011] Furthermore, the outer wall of the housing is rotatably connected to the outer wall of the fixed platform.

[0012] Furthermore, the outer wall of the motor is fixedly connected to the outer wall of the support frame, and the outer wall of the slide rail is fixedly connected to the outer wall of the support frame.

[0013] Furthermore, the outer wall of the lead screw is rotatably connected to the inner wall of the support frame.

[0014] This utility model has the following beneficial effects: In this invention, the fixed block is moved by a cylinder, which pushes one end of the second connecting rod to move and rotate simultaneously. The other end of the second connecting rod pushes the first connecting rod to rotate outward or inward around the end connected to the housing, causing the grippers to open or clamp. The second motor directly drives the housing to rotate the entire fixture. This solves the problems of needing to be in close contact with the forging area when manually flipping forgings, being easily scratched by flying metal oxide scale, and having slow flipping speed and large angle deviation. It achieves the effects of shortening the flipping time, increasing the flipping accuracy, reducing the time spent on auxiliary processes, and reducing the risks of manual operation.

[0015] In this invention, rotating the knob drives the threaded pin to rotate, the connecting block pushes and pulls the push plate to move, and the position of the sub-clamping block is adjusted. When clamping the forging, the sub-clamping block compresses the spring according to the shape of the forging, and the extension amount is adjusted. The spring rebound force is converted into clamping force to clamp the forging. This solves the problems of easy slippage and uneven force when clamping irregular forgings, and achieves a full fit when clamping irregular forgings, improving the anti-slip performance and stability.

[0018] 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.

[0019] Reference Figure 1 , Figure 2 and Figure 3 An embodiment of this utility model provides a forging flipping and clamping device, including a fixed platform 7, a support column 6 for supporting clamps fixedly connected to the lower surface of the fixed platform 7, a slider 5 fixedly connected to the lower surface of the support column 6, a slide rail 2 for providing a track for the slider 5 to slide slidably connected to the inner wall of the slider 5, a lead screw 3 for driving the slider 5 threadedly connected to the inner wall of the slider 5, one end of the lead screw 3 is fixedly connected to the output end of a motor 4 that drives the lead screw 3 to rotate, and the other end of the lead screw 3 is rotatably connected to a support frame 1 for supporting the lead screw 3 and the slide rail 2, and a flipping assembly is provided on the inner wall of the fixed platform 7; The flipping assembly includes a second motor 8. The outer wall of the second motor 8 is fixedly connected to the inner wall of the fixed platform 7 that provides support for the second motor 8. The output end of the second motor 8 is fixedly connected to a housing 9 that stabilizes the movement of the clamp. The inner wall of the housing 9 is fixedly connected to a cylinder 14 that drives the movement of the clamp. The output end of the cylinder 14 is fixedly connected to a fixed block 12 that is driven by the cylinder 14. The outer wall of the fixed block 12 is rotatably connected to a second connecting rod 11 that pushes and pulls the clamp to open and close. The inner wall of the housing 9 is rotatably connected to a first connecting rod 10 that is rotated by the thrust of the second connecting rod 11. The outer wall of the first connecting rod 10 is fixedly connected to a jaw 13 that clamps the forging.

[0020] Specifically, when it is necessary to clamp and flip the forging, the cylinder 14 pushes the fixed block 12 to move outward, the connecting rod 11 is subjected to force and rotates outward with the point connected to the fixed block 12 as the axis. When the connecting rod 11 rotates, it pushes the connecting rod 10 to rotate outward with the point connected to the housing 9 as the axis, which drives the gripper 13 to open. Then the cylinder 14 drives the fixed block 12 to move in the opposite direction and the gripper 13 to clamp the forging. The motor 8 drives the housing 9 to rotate and drives the entire fixture to rotate, thus completing the flipping of the forging.

[0021] Reference Figure 1 , Figure 4 and Figure 5 The inner wall of the gripper 13 is threaded with a threaded pin 20. One end of the threaded pin 20 is fixedly connected to a knob 21. The user rotates the knob 21 to adjust the position of the threaded pin 20. The other end of the threaded pin 20 is fixedly connected to a connecting block 22 for fixing the threaded pin 20. The outer wall of the connecting block 22 is rotatably connected to a push plate 19 that slides inside the gripper 13. The outer wall of the push plate 19 is fixedly connected to a stable clamping shell 18. The gripper 13 is equipped with a spring 17 that converts elastic force into clamping force. One end of the spring 17 is fixedly connected to the inner wall of the shell 18. The other end of the spring 17 is fixedly connected to a connecting plate 16 that stabilizes the clamping position. The outer wall of the connecting plate 16 is fixedly connected to a sub-clamping block 15. The outer wall of the push plate 19 is slidably connected to the inner wall of the gripper 13. The connecting plate 16 is slidably connected to the inner wall of the shell 18 that stabilizes the movement of the spring 17. The sub-clamping block 15 is slidably connected to the inner wall of the gripper 13. The outer wall of the sub-clamping block 15 is slidably connected to the inner wall of the shell 18.

[0022] Specifically, when clamping irregular forgings, the knob 21 is rotated according to the size and shape of the forging, which drives the threaded pin 20 to rotate together and move back and forth on the inner wall of the jaw 13. The connecting block 22 fixes the threaded pin 20 on the push plate 19 and moves together with the threaded pin 20. This adjusts how much the sub-clamping block 15 protrudes from the jaw 13. When clamping the forging, the sub-clamping block 15 is compressed by the spring 17. The extension of the sub-clamping block 15 varies depending on the shape of the forging. When clamping the forging, the forging is fully fitted, and the elastic force of the spring 17 is converted into clamping force to clamp the forging.

[0023] Reference Figure 1 The outer wall of the housing 9 is rotatably connected to the outer wall of the fixed platform 7 of the support and fixing fixture. The outer wall of the motor 4 is fixedly connected to the outer wall of the support frame 1 for supporting the motor 4. The outer wall of the slide rail 2 is fixedly connected to the outer wall of the support frame 1 for supporting the slide rail 2. The outer wall of the lead screw 3 is rotatably connected to the inner wall of the support frame 1 for supporting the lead screw 3.

[0024] Specifically, motor 4 drives lead screw 3 to rotate, and adjusts slider 5 to position on slide rail 2 through threaded transmission, which in turn moves support column 6 and clamp connected above it. When clamp 13 reaches the appropriate position, motor 4 stops driving slider 5 to fix it, thus completing the position adjustment.

[0025] Working principle: When it is necessary to clamp and flip the forging, firstly, cylinder 14 pushes the fixed block 12 to move outward. The fixed block 12 pushes the connecting rod 11 to rotate outward around the point connected to the fixed block 12. The connecting rod 11 pushes the connecting rod 10 to rotate outward around the axis connected to the housing 9, causing the gripper 13 to open. Then, motor 4 drives the lead screw 3 to rotate. The rotation of the lead screw 3 drives the slider 5 to slide on the slide rail 2 on the support frame 1, causing the support column 6 and the clamp connected above to move together. When the appropriate clamping position is reached, motor 4 stops driving, the slider 5 stops moving, and cylinder 14 drives the fixed block 12 to move in the opposite direction, causing the clamp to open. The jaw 13 closes and clamps the forging. When it encounters an irregularly shaped forging, the knob 21 is turned according to the shape and size of the forging, which drives the threaded pin 20 to rotate. The connecting block 22 connected to one end of the threaded pin 20 is connected to the push plate 19. As the threaded pin 20 rotates, it pushes and pulls to move the position of the push plate 19 in the jaw 13, thereby adjusting the position of the sub-clamping block 15. When clamping an irregular forging, the sub-clamping block 15 compresses the spring 17 according to the different forces, and adjusts the sub-clamping block 15 to the most suitable extension amount to achieve full fit with the forging. The spring 17 rebound pressure is converted into clamping force to clamp the forging. Finally, the motor 2 8 on the fixed platform 7 drives the housing 9 to rotate, and the fixture drives the forging to flip.

[0026] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
