Description

Technical Field

[0001] The present invention relates to the technical field of copper strip processing equipment, and specifically relates to a high-precision special-shaped copper strip forging and forming device. Background Art

[0002] Forged copper strip refers to a process in which pressure is applied to copper materials using a press machine at high or normal temperature to cause plastic deformation, thereby changing the shape, size, and properties of the copper material. This process is very common in the field of metal processing and plays an important role in improving the mechanical properties and internal organizational structure of copper materials. However, in the prior art, in most forging processes, manual placement at the forging location is used for forging. Such a forging method not only easily causes tilting of the position and an increase in cost, but also during the forging process, the copper strip may maintain a certain temperature and hardness, causing burns or scratches to the hands. Based on this, the present invention proposes a high-precision special-shaped copper strip forging and forming device to solve the above problems. Summary of the Invention

[0005] The clamping device includes a moving device and a grasping device. The moving device includes a motor, and the motor drives the moving device to rotate. Since the grasping device is fixedly connected to the moving device, the rotation of the moving device drives the grasping device to change direction to grasp the forged copper strip.

[0006] As a preferred technical solution of the present invention, two long columns are movably connected to the inner grooves of the two groove blocks, and both ends of the two long columns are connected to the hollow part inside the forging groove.

[0007] As a preferred technical solution of the present invention, push rods are movably connected to both sides of the two groove blocks, rotating blocks are movably connected to the bottoms of the four push rods, a first rotating shaft is movably connected to the centers of the two rotating blocks, and the bottoms of the two first rotating shafts are movably connected to both sides of the hollow part inside the forging groove. Connecting rods are fixedly connected to the tops of the two groove blocks, and a model block is fixedly connected to the tops of the two connecting rods.

[0008] As a preferred technical solution of the present invention, the moving device includes two elliptical plates, a moving block is movably connected between the two elliptical plates, bandages are movably connected to the outer surfaces of the two moving blocks, a second rotating shaft is fixedly connected to the bottom of one of the moving blocks, and a first gear is fixedly connected to the bottom of the second rotating shaft.

The first gear and the second gear are movably connected to the bottom plate, and one end of the bottom plate is fixedly connected to the top of one side of the forging equipment body. A motor is fixedly connected to the bottom of the bottom plate.

[0009] As a preferred technical solution of the present invention, rotating columns are movably connected to both ends of the two elliptical plates, and the outer surface of the top of one of the rotating columns penetrates through the center of one of the moving blocks. Connecting blocks are fixedly connected to the bottoms of the two rotating columns, and grasping devices are fixedly connected to the bottoms of the two connecting blocks.

[0010] As a preferred technical solution of the present invention, the grasping device includes a polygonal block, the top of the polygonal block is fixedly connected to the bottom of the connecting block, support rods are fixedly connected to both ends of the bottom of the polygonal block, third rotating shafts are movably connected to the bottoms of the two support rods, and a gripper is movably connected to the centers of the two third rotating shafts.

[0011] As a preferred technical solution of the present invention, telescopic columns are movably connected to both sides of the center of the bottom of the polygonal block, long blocks are fixedly connected to the bottoms of the two telescopic columns, swing plates are movably connected to both sides of the two long blocks, and the inner sides of the bottoms of the two swing plates are movably connected to the top of the gripper.

[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] (1) A high-precision special-shaped copper strip forging and forming device. By correspondingly arranging the fixing device at the bottom of the stamping equipment, the copper strip can be forged completely and without deviation by using the fixing of the fixing device. This stability is crucial for obtaining forged parts with precise dimensions and regular shapes. The gripper device located on one side of the top of the forging equipment body avoids direct contact between the operator and the high-temperature and hard copper strip through the gripper of the grasping device, preventing possible burns or scratches on the hands caused by the temperature and hardness of the copper strip during the forging process. This grasping method can reduce safety risks.

[0014] (2) A high-precision special-shaped copper strip forging and forming device. By setting the bottom end of one of the groove blocks to be connected to the output shaft end of the cylinder, it can utilize the push of the cylinder to slide the groove block on the outer surfaces of the two long columns. At this time, the push rods located on both sides of the groove block will move forward. The bottom end of the push rod is also movably connected to the convex part of the rotating block. Therefore, under the rotation of the first rotating shaft movably connected to the center of the rotating block, the rotating block will quickly pull the push rods connected at both ends and the model block corresponding to the top of the groove block towards the middle, thereby fixing the bottom or both sides of the copper strip to ensure that the copper strip will not displace or warp during the forging process, maintaining its stability and accuracy.

[0015] (3) A high-precision special-shaped copper strip forging and forming device. By setting a connecting first gear on the top of the motor, it can be rotated by the drive of the motor. The outer surface of the first gear is meshed and connected with the second gear. With the rotation of the two gears, not only can the rotation flexibility be improved, but also the movement process can be made more stable, reducing noise and vibration caused by friction and imbalance. The top of the first gear is fixedly connected to the bottom of the second rotating shaft. Therefore, the first gear can drive the movable block connected to the top to move.

[0016] (4) A high-precision special-shaped copper strip forging and forming device. By movably connecting the outer surface of the movable block to the inner surface of the bandage, and the bandage is a flexible transmission belt for synchronizing the rotational movements of the two movable blocks, so as to facilitate the gripping device fixedly connected to the bottom of the connecting block to grip the forged copper strip. Compared with the traditional removal method, it may require more time and labor, and is easy to damage the copper strip. By adopting the rotational gripping method, the copper strip can be positioned and gripped more quickly and accurately, greatly improving the disassembly efficiency.

[0017] (5) A high-precision special-shaped copper strip forging and forming device. By connecting the top of the multi-sided block to the bottom of the connecting block, it is convenient for the gripping device to grip the copper strip by constantly changing positions. When the telescopic columns movably connected to both sides of the bottom center of the multi-sided block also extend upward under the drive of the motor, they will drive the long strip block fixedly connected to the bottom to move upward. At this time, the inner side of the top end of the swing plate will contract the gripper movably connected to the bottom end towards the center under the pull of the long strip block, and finally quickly and accurately clamp the forged copper strip and move it out of the working area, reducing the time and labor required for manual handling, thereby improving the overall production efficiency.

At the center of the top of the forging table 2, there is a fixing device 3, and the center of the top of the forging table 2 is connected to the bottom of the fixing device 3. By correspondingly arranging the fixing device 3 at the bottom of the stamping equipment 4, the copper strip can be forged completely and without deviation by using the fixation of the fixing device 3. This kind of stability is crucial for obtaining forged parts with precise dimensions and regular shapes. And the clamping device 5 located on one side of the top of the forging equipment body 1 can avoid direct contact between the operator and the high-temperature and hard copper strip through the clamping of the clamping device 52, preventing the possible temperature and hardness of the copper strip during forging from scalding or scratching the hand. This clamping method can reduce safety risks. At the top of the fixing device 3, there is a stamping equipment 4, and the top of the fixing device 3 is correspondingly connected to the bottom of the stamping equipment 4. On one side of the top of the forging equipment body 1, there is a clamping device 5, and one side of the top of the forging equipment body 1 is fixedly connected to one end of the clamping device 5. The fixing device 3 includes a forging groove 31. Inside the hollow part of the forging groove 31, there is a moving device 32. When the stamping equipment 4 presses down, the moving device 32 can quickly move from the hollow part inside the forging groove 31 to the center, so as to help fix both sides of the copper strip during forging;

[0029] The clamping device 5 includes a moving device 51 and a clamping device 52. The moving device 51 will first be driven to rotate by a motor 518 connected to the bottom. The clamping device 52 is fixedly connected to the moving device 51. Therefore, when rotating, it will drive the clamping device 52 to move together, so as to sensitively clamp the forged copper strip and avoid the risk of scalding or scratching caused by the operator's contact with the high-temperature or high-hardness copper strip.

[0030] The moving device 32 includes two groove blocks 322. At the bottom end of one of the groove blocks 322, there is a cylinder 321, and the bottom end of one of the groove blocks 322 is fixedly connected to the output shaft end of the cylinder 321. Inside the grooves of the two groove blocks 322, there are two long columns 323, and the inner grooves of the two groove blocks 322 are movably connected to the outer surfaces of the two long columns 323.

On the tops of the two groove blocks 322, there are connecting rods 327, and the tops of the two groove blocks 322 are fixedly connected to the bottoms of the connecting rods 327. By setting the bottom end of one of the groove blocks 322 to be connected to the output shaft end of the air cylinder 321, the groove block 322 can be slid on the outer surfaces of the two long columns 323 by the push of the air cylinder 321. At this time, the push rods 324 located on both sides of the groove block 322 will move forward. The bottom ends of the push rods 324 are movably connected to the protruding parts of the rotating blocks 325. Therefore, under the rotation of the first rotating shaft 326 movably connected to the center of the rotating block 325, the rotating block 325 will quickly pull the push rods 324 connected to both ends and the model block 328 corresponding to the top of the groove block 322 to move towards the middle, thereby fixing the bottom or both sides of the copper strip to ensure that the copper strip will not be displaced or warped during the forging process and maintain its stability and accuracy. On the tops of the two connecting rods 327, there is a model block 328, and the tops of the two connecting rods 327 are fixedly connected to the bottom of the model block 328.

[0032] The movable device 51 includes two elliptical plates 511. A movable block 512 is arranged between the two elliptical plates 511, and both ends of the two elliptical plates 511 are movably connected to both ends of the movable block 512. Bandages 513 are arranged on the outer surfaces of the two movable blocks 512, and the outer surfaces of the two movable blocks 512 are movably connected to the interiors of the bandages 513. A second rotating shaft 514 is arranged at the bottom of one of the movable blocks 512, and the bottom of one of the movable blocks 512 is fixedly connected to the top of the second rotating shaft 514.

A second gear 516 is arranged on the outer surface of the first gear 515, and the outer surface of the first gear 515 is meshed with the outer surface of the second gear 516. By arranging a connection to the first gear 515 on the top of the motor 518, rotation can be carried out by the drive of the motor 518. The outer surface of the first gear 515 is meshed with the second gear 516 together. With the rotation of the two gears, not only can the rotation flexibility be improved, but also the movement process can be made more stable, reducing noise and vibration caused by friction and imbalance. The top of the first gear 515 is fixedly connected to the bottom of the second rotating shaft 514, so the first gear 515 can drive the movable block 512 connected to the top to move. The bottom of the first gear 515 and the second gear 516 is provided with a bottom plate 517, and the bottoms of the first gear 515 and the second gear 516 are movably connected to the protruding part on the top of the bottom plate 517. One end of the bottom plate 517 is fixedly connected to the top of one side of the forging equipment body 1. A motor 518 is arranged at the bottom of the bottom plate 517, and the bottom of the bottom plate 517 is fixedly connected to the top of the motor 518.

[0033] Rotating columns 519 are arranged at both ends of the two elliptical plates 511, and both ends of the two elliptical plates 511 are movably connected to the outer surfaces of the tops of the rotating columns 519. The outer surface of the top of one of the rotating columns 519 penetrates through the center of one of the movable blocks 512. Connecting blocks 5110 are arranged at the bottoms of the two rotating columns 519, and the bottoms of the two rotating columns 519 are fixedly connected to the tops of the connecting blocks 5110. Gripping devices 52 are arranged at the bottoms of the two connecting blocks 5110. By movably connecting the outer surface of the movable block 512 to the inner surface of the bandage 513, and the bandage 513 is a flexible transmission belt for synchronizing the rotational movements of the two movable blocks 512, so as to facilitate the gripping device 52 fixedly connected to the bottom of the connecting block 5110 to grip the copper strip after forging. Compared with the traditional removal method, it may require more time and manpower, and is prone to damage the copper strip. By adopting the rotational gripping method, the copper strip can be positioned and gripped more quickly and accurately, greatly improving the disassembly efficiency. The bottoms of the two connecting blocks 5110 are both fixedly connected to the tops of the gripping devices 52.

[0034] The grasping device 52 includes a multi-sided block 521. The top of the multi-sided block 521 is fixedly connected to the bottom of the connecting block 5110. Both ends of the bottom of the multi-sided block 521 are provided with support rods 522, and both ends of the bottom of the multi-sided block 521 are fixedly connected to the tops of the support rods 522. Third rotating shafts 523 are provided at the bottoms of both support rods 522, and both ends of the bottoms of both support rods 522 are movably connected to both ends of the third rotating shafts 523. A gripper 524 is provided at the centers of both third rotating shafts 523, and the centers of both third rotating shafts 523 are movably connected to the convex parts at the centers of the gripper 524.

[0035] On both sides of the center of the bottom of the multi-sided block 521, telescopic columns 525 are provided, and both sides of the center of the bottom of the multi-sided block 521 are movably connected to the tops of the telescopic columns 525.

By connecting the top of the multi-sided block 521 and the bottom of the connecting block 5110 together, it is convenient for the grasping device 52 to continuously change its position to grasp the copper strip. When the telescopic columns 525 movably connected to both sides of the center of the bottom of the multi-sided block 521 are driven by the motor 518 to extend upward, they will drive the long bar blocks 526 fixedly connected to the bottom to move upward as well. At this time, the inner sides of the tops of the swing plates 527 will be pulled by the long bar blocks 526, and the gripper 524 movably connected to the bottom ends will contract and move toward the center. Finally, it quickly and accurately clamps the copper strip after forging and moves it out of the working area, reducing the time and labor required for manual handling, thereby improving the overall production efficiency. And both sides of both long bar blocks 526 are movably connected to the inner sides of the tops of the swing plates 527, and the inner sides of the bottoms of both swing plates 527 are movably connected to the tops of the gripper 524.

[0036] The working principle of the present invention is as follows:

[0037] First, place the copper strip to be forged above the fixing device 3, and then perform forging with the stamping equipment 4. Immediately afterwards, it is grabbed and moved to the next place by the gripping device 5. At the same time, the use of the gripper can prevent the operator from directly contacting the high-temperature and hard copper strip, reducing the safety risk. The fixing device 3 includes a forging groove 31 and a moving device 32. When the cylinder 321 in the moving device 32 pushes the groove block 322 fixedly connected to the output shaft end forward, it will only slide back and forth on the outer surfaces of the two long columns 323. When the push rods 324 movably connected to both sides of the groove block 322 are pushed to translate, they will push the rotating block 325 movably connected to the other end to twist in one direction, so that the other push rod 324 located at the bottom of the rotating block 325 can also be pulled over. Finally, the groove blocks 322 at different positions at both ends can drive the model blocks 328 correspondingly connected to the top to move towards the middle, and fixing both sides can provide necessary support and guidance during the forging process to prevent the copper strip from being distorted or deformed when stressed. This supporting effect helps to maintain the flatness and consistency of the copper strip, ensuring that the quality of the forged parts meets the design requirements.

[0038] The gripping device 5 includes a moving device 51 and a gripping device 52. When the motor 518 in the moving device 51 drives the first gear 515 correspondingly connected to the top to rotate, the first gear 515 will quickly drive the second gear 516 meshed with its outer surface to twist together. The meshing rotation of the two gears can achieve high-precision motion transmission, ensuring the precision and flexibility of the mechanical device. The second rotating shaft 514 is connected to the movable block 512 and the first gear 515 respectively up and down. Therefore, the movable block 512 will rotate following the first gear 515 at the bottom. After rotation, the movable block 512 will, through the connection of the bandage 513, enable the same movable block 512 connected to the outer surface of the rotating column 519 at the other end to also move, so as to continuously change the positions of both sides of the gripping device 5 connected to the bottom of the connecting block 5110 to grip both sides of the copper strip. In addition, the design of rotating and gripping usually also takes into account the simplicity and safety of the operation, which can reduce the labor intensity of workers and improve work efficiency.

[0039] The gripping device 52 includes a telescopic column 525. When the telescopic column 525 moves upward under the drive of the motor 518, it will pull the long strip block 526 fixedly connected to the bottom upward. At this time, the swing plates 527 movably connected to both sides of the long strip block 526 will be pulled, and then pull the grippers 524 movably connected to the bottom ends of the swing plates 527 to move towards the center, so as to quickly grip both sides of the copper strip to avoid sliding during the movement. Therefore, using the gripper to remove the forged copper strip can ensure the shape and dimensional accuracy of the product and maintain the product quality.
