Description

Technical Field

[0001] The invention relates to the technical field, in particular to a clamp device for a cold heading machine for producing hardware accessories of industrial automation equipment. Background Art

[0002] In the production process of hardware accessories, cold heading technology is often used for plastic forming of metal materials. The cold heading machine completes the mold forming by high-pressure extrusion of the metal workpiece. With the continuous development of industrial automation technology, the cold heading machine is a key equipment in the production process of hardware accessories. Its performance directly affects the quality and production efficiency of the product. The clamp device of the cold heading machine is an important part of the cold heading machine. Its main function is to clamp and convey hardware accessories during the production process to ensure that the accessories are accurately positioned during the cold heading process, thereby achieving efficient and precise production.

[0003] For example, the application number is 201810815893.3, a clamp device for cold heading machine for producing hardware accessories for industrial automation equipment.

[0004] The above patent proposes a clamp device for a cold heading machine for producing hardware accessories of industrial automation equipment, including a support frame, a circular slide groove is arranged on the top of the support frame, a circular hollow rotating cylinder is arranged directly below the support frame, the top of the circular hollow rotating cylinder is connected to the circular slide groove through an annular slider, two connecting protrusions are arranged at the lower end of the inner wall of the circular hollow rotating cylinder, and the connecting protrusions are respectively movably connected to the left clamp arm and the right clamp arm through a pin shaft, a driving cylinder is arranged inside the circular hollow rotating cylinder, and the output end of the driving cylinder is connected to the driving shaft, a transverse adjustment plate is arranged directly below the driving shaft, a connecting block is arranged on the top of the transverse adjustment plate, and the connecting block is connected to the driving shaft through a rotating bearing, and adjusting sliders are arranged at both ends of the transverse adjustment plate, and the top of the inner side surfaces of the left clamp arm and the right clamp arm are provided with adjustment slide grooves matching the adjusting sliders. The clamping force of the device is greater, which can prevent the accessories from falling off during the clamping process, and at the same time, the angle of the accessories can be accurately adjusted.

[0005] There are still some shortcomings in the application of the above technical scheme. The clamping device of the cold heading machine usually includes a left clamping piece and a right clamping piece. The central part of the left clamping piece and the right clamping piece are hinged together, and the top ends of the left clamping piece and the right clamping piece are movably connected through a connecting arm. The connecting arm is connected to the lifting shaft of the lifting cylinder. When the lifting cylinder drives the connecting arm to move up and down, the bottom ends of the left clamping piece and the right clamping piece can complete the opening and closing operation, thereby realizing the clamping and transportation of the accessories. Since the design of the clamping arm in the clamping device is relatively simple and the flexibility is poor, there is a situation where it cannot adapt to the complex shapes and sizes of the accessories when clamping the accessories. Due to the mismatch and low height with the accessories, the clamping is not accurate enough, and there is no anti-falling structure. The accessories may fall off due to external force during the clamping process, resulting in production interruption and material waste, causing safety accidents.

[0006] Therefore, we propose a clamp device for cold heading machine for hardware accessories production of industrial automation equipment to solve the above-mentioned problems. Summary of the invention

[0049] Embodiment 2: This embodiment is an improvement made on the basis of embodiment 1. For details, please refer to Figure 6-Figure 8 ,

[0050] In this embodiment: the left side above the support frame 1 is rotatably connected to a bevel gear column 4 23, the right side above the support frame 1 is rotatably connected to a bevel gear column 3 18, one end of the bevel gear column 3 18 is slidably connected to a connecting rod 19, the connecting rod 19 is connected to a threaded rod 1 3, one end of the bevel gear column 4 23 is slidably connected to a connecting rod 24, the connecting rod 24 is connected to a threaded rod 2 4, the center position above the support frame 1 is rotatably connected to a bevel gear 1 22, the bevel gear 1 22 is meshed with the bevel gear column 4 23, the bevel gear 1 22 is meshed with the bevel gear column 3 18, and the center position above the fixed frame 5 is rotatably connected to a bevel gear 25, bevel gear 25 meshes with threaded rod 3 15, bevel gear 25 meshes with threaded rod 4 16, a track groove 26 is provided in the fixed frame 5, a plurality of rollers 27 are rotatably connected to the outer surface of the movable plate 2 17, the rollers 27 are rollingly connected in the track groove 26, and both ends of the threaded rod 3 15 and the threaded rod 4 16 are provided with bevel gears, the threaded rod 3 15 and the threaded rod 4 16 are meshed with bevel gear 25 through bevel gears, and the bevel gear column 1 101, the bevel gear column 2 1202, the bevel gear column 3 18 and the bevel gear column 4 23 are all composed of a rotating rod and a bevel gear;

[0051] By setting the threaded rod three 15, the threaded rod four 16 and the bevel gear two 25, since one end of the threaded rod four 16 is meshed with the bevel gear two 25, and one end of the threaded rod three 15 is meshed with the bevel gear two 25, the threaded rod three 15 and the threaded rod four 16 can realize the function of synchronous reverse rotation, so that the movable plate one 6 and the movable plate two 17 can move relatively in the fixed frame 5, and the movable plate one 6 and the movable plate two 17 can move in the fixed frame 5 to clamp accessories of different sizes, avoiding the phenomenon that it is difficult to clamp special accessories due to limited expansion space of the clamp, thereby ensuring the applicability of the clamp device;

[0052] The transmission structure 11 includes a bevel gear column 1101 and a turntable 1102. The bevel gear column 1101 is rotatably connected to the top of the fixed frame 5. The turntable 1102 is fixedly connected to the top of the rotating rod 13. The turntable 1102 is externally connected to an anti-skid belt 1103. The turntable 1102 is connected to the threaded rod 3 through the anti-skid belt 1103. The bevel gear column 1101 is slidably connected in the groove 21.

[0053] By providing the rotating rod 13 and the groove 21, when the threaded rod 13 and the threaded rod 24 are rotating, the fixing frame 5 will move on its surface, and the bevel gear column 1101 will slide in the groove 21 provided in the rotating rod 13, so that the rotating rod 13 and the groove 21 play a certain auxiliary role in the movement of the bevel gear column 1101. When the bevel gear column 1101 moves to any position, it can still drive the rotating rod 13 to rotate, and the rotation movement will not be interrupted during the operation, thereby improving the production efficiency.

[0054] The driving structure 12 includes a vertical plate 1201 and a second telescope 1206. The vertical plate 1201 is slidably connected in a cavity provided in the fixed frame 5.

[0055] By setting the limit plate 1205, when the telescopic device 1206 drives the vertical plate 1201 to move, the limit plate 1205 on the right side of the bevel gear column 1202 will be clamped with the threaded rod 4 16, so that the limit plate 1205 plays a certain positioning role for the threaded rod 4 16, and the bevel gear column 1202 and the threaded rod 4 16 can realize the function of synchronous rotation, thereby avoiding the phenomenon that the threaded rod 4 16 gets stuck when the bevel gear column 1202 rotates.

[0056] Working principle:

[0057] When the clamp device is in use, a thrust is applied to the vertical plate 1201 through the telescopic device 2 1206, and the vertical plate 1201 slides in the fixed frame 5. When the vertical plate 1201 moves to an appropriate position, the bevel gear column 2 1202 comes into contact with the bevel gear column 1 1101. Since the output shaft of the motor 3 1203 is meshed with the bevel gear column 2 1202 through the anti-slip belt 3 1204, the bevel gear column 2 1202 rotates along with the motor 3 1203, and the bevel gear column 1 1101 rotates synchronously with the bevel gear column 2 1202. It will drive the rotating rod 13 to rotate in the support frame 1. Since the rotating disk 1102 is connected to the threaded rod 13 through the anti-slip belt 2 1103, the rotating rod 13 and the threaded rod 13 will rotate synchronously. The threaded rod 13 is connected to the bevel gear column 3 18 through the connecting rod 19 at the top. The threaded rod 24 is connected to the bevel gear column 4 23 through the connecting rod 24 at the top. The bevel gear column 3 18 and the bevel gear column 4 23 are both meshed with the bevel gear 1 22, so that the threaded rod 13 and the threaded rod 24 will rotate synchronously, and the fixed frame 5 will move on the surface of the threaded rod 13 and the threaded rod 24.

[0058] When the fixing frame 5 moves to the appropriate position, the vertical plate 1201 is driven to recover through the telescopic device 2 1206. The vertical plate 1201 will be separated from the bevel gear column 1 1101 during recovery. The limit plate 1205 on the left side of the bevel gear column 2 1202 will be engaged with the threaded rod 4 16. The threaded rod 4 16 is meshed with the bevel gear 2 25. The threaded rod 3 15 is meshed with the bevel gear 2 25. The threaded rod 3 15 and the threaded rod 4 16 will rotate synchronously with the bevel gear column 2 1202. The support arm 7 and the movable plate 2 17 will move on the surfaces of the threaded rod 3 15 and the threaded rod 4 16.

[0059] When the moving plate 1 6 and the moving plate 2 17 move relative to each other, they will come into contact with the accessories. When they come into contact with the accessories, the clamping arm 9 is driven to rotate by the motor 1 803.
