Description

Technical Field

[0001] This utility model relates to the field of copper strip processing technology, specifically a cutting mechanism with anti-deviation function. Background Technology

[0002] Shaped copper strips refer to copper strip materials with complex shapes and specific dimensions, formed through specific processing techniques. Generally, shaped copper strips are created by cutting, stamping, bending, and other processes from flat copper strips to form specific geometric shapes to meet the needs of various industrial applications. These copper strips are widely used in electronic components, connectors, conductors, and various precision mechanical parts.

[0003] Cutting is a crucial step in the manufacturing of irregularly shaped copper strips. Copper strip cutting equipment is mainly used to cut large rolls of copper strips into the required lengths for subsequent processing. However, the positioning and stability of the copper strip are critical during the actual cutting process. Due to the characteristics of copper strip material, offset often occurs during cutting. This offset not only leads to uneven cut edges but can also cause processing errors in subsequent steps, seriously affecting the quality of the final product.

[0004] Patent CN216705725U discloses a copper strip cutting device for preventing deviation, including a base, a support frame, a telescopic mechanism, cutting shears, and a storage groove. The support frame is fixed above the base to support the telescopic mechanism, and the cutting shears are located below the telescopic mechanism. The storage groove is also located below the cutting shears, and is situated on the upper surface of the base to provide downward space for the cutting shears. A mounting plate is fixed to the lower surface of the telescopic mechanism. An adsorption cavity is formed on the upper surface of the base, and a sealing plug is installed inside the adsorption cavity. This copper strip cutting device for preventing deviation, with its adsorption cavity and sealing plug, generates suction within the adsorption cavity by the movement of the sealing plug, adsorbing the copper strip onto the base. This ensures good stability of the copper strip during subsequent cutting. Furthermore, the movement of the piston can be controlled by the telescopic mechanism, achieving automatic adsorption during cutting.

[0005] However, existing technologies using telescopic mechanisms to drive the cutting shears still have certain problems. Because the storage groove is directly below the cutting shears, the copper strip may deform when downward pressure is applied, especially at the cutting point. This deformation not only leads to instability in the shape of the copper strip but can also cause severe stretching and deformation, thus affecting the quality and accuracy of the cut copper strip. To overcome this deficiency, we propose a cutting mechanism with an anti-deviation function, which can reduce deformation during the cutting process while ensuring the stability of the copper strip, further improving cutting quality and efficiency. Utility Model Content

[0006] The purpose of this invention is to provide a cutting mechanism with an anti-deviation function to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A cutting mechanism with anti-deviation function includes a worktable, combined with Figure 1 and Figure 2 As shown, a cutting assembly is provided on the rear side of the top of the workbench. The cutting assembly is used to drive the cutter to complete the copper strip cutting action. The cutting assembly includes a fixed vertical plate that is bolted to the top of the workbench. A cylinder is provided on the rear side of the fixed vertical plate near the top via a mounting plate. An external pneumatic drive system is connected to the cylinder. The end of the cylinder's movable rod passes through the rear side of the fixed vertical plate and is fixedly connected to a movable seat. The cylinder drives the movable seat to move back and forth, causing the cutter to move from back to front to cut the copper strip. The movable seat is used to transmit the power of the cylinder and drive the cutter to move. A mounting vertical plate is provided at the bottom of the movable seat. The mounting vertical plate is used to install a motor and a cutter. A motor is provided on the left side of the mounting vertical plate. The motor is used to drive the cutter to rotate at high speed. An external power supply and controller are connected to the motor. The output shaft of the motor passes through the left side of the mounting vertical plate and is coaxially connected to the cutter. The cutter is used to cut the copper strip.

[0009] The top of the workbench has a strip-shaped hole to avoid the bottom of the cutter. The strip-shaped hole is used to prevent the cutter from directly contacting the workbench and causing wear. The top of the workbench and the left and right sides of the strip-shaped hole are both equipped with width limiting components. The width limiting components are used to adjust the position of the copper strip in the width direction and prevent lateral deviation. The top of the workbench and the outside of the two width limiting components are both equipped with auxiliary positioning components. The auxiliary positioning components are used to press the top of the copper strip to prevent vertical jumping.

[0010] Preferred, such as Figure 2 As shown, a limiting rod is provided on the rear side of the movable seat. The rear end of the limiting rod passes through the front side of the fixed vertical plate to the outside. The limiting rod is used to limit the movement trajectory of the movable seat and ensure the motion accuracy.

[0011] Preferred, such as Figure 3 As shown, the width limiting assembly includes a fixed seat that is bolted to the top of the workbench. The front side of the fixed seat is threadedly connected to a threaded rod. The threaded rod is used to manually adjust the front and rear positions of the movable limiting plate to accommodate copper strips of different widths. The rear end of the threaded rod is rotatably connected to the movable limiting plate. The bottom of the movable limiting plate is in contact with the top of the workbench.

[0012] The width limiting assembly also includes a fixed limiting plate that is bolted to the top of the worktable. The fixed limiting plate is located directly behind the movable limiting plate. Rubber pads can be glued to the opposite sides of the movable and fixed limiting plates. After the copper strip is placed on the top of the worktable, the position of the movable limiting plate is adjusted so that the front and rear sides of the copper strip are in contact with the opposite sides of the movable and fixed limiting plates, respectively, which limits the subsequent movement of the copper strip and prevents the copper strip from shifting forward or backward.

[0013] Preferred, such as Figure 4 As shown, the auxiliary positioning component includes a U-shaped plate bolted to the top of the workbench. The U-shaped plate and the fixed limiting plate are arranged perpendicularly. An electric telescopic rod is provided at the top of the U-shaped plate and near the rear. The electric telescopic rod is used to drive the strip pressure plate to move up and down to press the copper strip. It is powered by an external power supply and controller. The movable rod of the electric telescopic rod passes through the top of the U-shaped plate and is fixedly connected to the strip pressure plate. A rubber pad can be set at the bottom of the strip pressure plate. The strip pressure plate limits the top of the copper strip. Together with the movable limiting plate and the fixed limiting plate, it can ensure that the copper strip will not shift during cutting and ensure the quality of the cut copper strip.

[0014] The rear side of the strip pressure plate is in contact with the front side of the fixed limiting plate, and the front side of the strip pressure plate is in contact with the front side of the inner wall of the U-shaped plate, thereby improving the stability of the strip pressure plate.

[0015] The bottom of the movable limiting plate and near the strip hole are provided with a U-shaped clearance opening to avoid the strip pressure plate. The U-shaped clearance opening is used to avoid interference between the movable limiting plate and the strip pressure plate when they move, so that the strip pressure plate can move up and down smoothly and the movable limiting plate can move back and forth smoothly.

[0016] A limiting vertical rod is provided at the top of the strip pressure plate and near the front side. The top of the limiting vertical rod passes through the top of the inner wall of the U-shaped plate to the outside. The limiting vertical rod is used for vertical guidance of the strip pressure plate and to ensure the pressing stability.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] 1. The cutting mechanism with anti-deviation function limits the front and rear sides of the copper strip through the movable limiting plate and the fixed limiting plate in the width limiting component. With the help of the strip pressure plate of the auxiliary positioning component, the top of the copper strip is pressed to achieve multi-directional limiting, ensuring that the copper strip is stable in position during the cutting process and avoiding deviation in the horizontal or vertical direction.

[0019] 2. The cutting mechanism with anti-deviation function uses a cylinder to drive the cutter to move horizontally instead of cutting vertically downwards. Combined with the strip hole of the worktable to avoid the bottom of the cutter, it avoids the copper strip from being stretched and deformed due to local stress, ensuring a flat cutting edge and improving the accuracy of the finished product.

[0020] 3. The cutting mechanism with anti-deviation function can quickly adjust the limit distance according to the width of the copper strip by manually adjusting the threaded rod to drive the movable limit plate. Combined with the vertical pressing function of the strip pressure plate, it can meet the processing needs of copper strips of various specifications.

[0021] 4. The cutting mechanism with anti-deviation function has a U-shaped clearance at the bottom of the movable limit plate to provide clearance space for the strip pressure plate, ensuring that the movement of the width limiting component and the auxiliary positioning component does not interfere with each other, and improving the efficiency of equipment collaborative work.

[0029] Please see Figures 1-4 This utility model provides a technical solution:

[0030] A cutting mechanism with anti-deviation function includes a worktable 100, combined with... Figure 1 and Figure 2 As shown, a cutting assembly 200 is provided on the rear side of the top of the workbench 100.

A cylinder 220 is provided on the rear side of the fixed vertical plate 210 near the top via a mounting plate. An external pneumatic drive system is connected to the cylinder. The end of the movable rod of the cylinder 220 passes through the rear side of the fixed vertical plate 210 and is fixedly connected to a movable seat 230. The cylinder 220 drives the movable seat 230 to move back and forth, causing the cutter 260 to cut. Moving from back to front, the copper strip is cut. The moving base 230 is used to transmit the power of the cylinder 220 and drive the cutter 260 to move. The bottom of the moving base 230 is provided with a mounting plate 240, which is used to mount the motor 250 and the cutter 260. The motor 250 is located on the left side of the mounting plate 240.

The output shaft of the motor 250 passes through the left side of the mounting plate 240 and is coaxially connected to the cutter 260. The cutter 260 is used to cut the copper strip.

[0031] The top of the workbench 100 is provided with a strip hole 110 to avoid the bottom end of the cutter 260. The strip hole 110 is used to prevent the cutter 260 from directly contacting the workbench 100 and causing wear. Width limiting components 300 are provided on the top of the workbench 100 and on both sides of the strip hole 110. The width limiting components 300 are used to adjust the position of the copper strip in the width direction and prevent lateral deviation. Auxiliary positioning components 400 are provided on the top of the workbench 100 and on the outside of the two width limiting components 300. The auxiliary positioning components 400 are used to press the top of the copper strip to prevent vertical jumping.

[0032] In this embodiment, as Figure 2As shown, a limiting rod 270 is provided on the rear side of the movable seat 230. The rear end of the limiting rod 270 passes through the front side of the fixed vertical plate 210 to the outside. The limiting rod 270 is used to limit the movement trajectory of the movable seat 230 and ensure the motion accuracy.

[0033] Specifically, such as Figure 3 As shown, the width limiting assembly 300 includes a fixed seat 310 that is bolted to the top of the worktable 100. The front side of the fixed seat 310 is threadedly connected to a threaded rod 320.

The rear end of the threaded rod 320 is rotatably connected to the movable limiting plate 330. The bottom of the movable limiting plate 330 is in contact with the top of the worktable 100.

[0034] The width limiting assembly 300 also includes a fixed limiting plate 340 that is bolted to the top of the worktable 100. The fixed limiting plate 340 is located directly behind the movable limiting plate 330. Rubber pads can be glued to the opposite sides of the movable limiting plate 330 and the fixed limiting plate 340. After the copper strip is placed on the top of the worktable 100, the position of the movable limiting plate 330 is adjusted so that the front and rear sides of the copper strip are respectively in contact with the opposite sides of the movable limiting plate 330 and the fixed limiting plate 340, which limits the subsequent movement of the copper strip and prevents the copper strip from shifting forward and backward.

[0035] Furthermore, such as Figure 4 As shown, the auxiliary positioning component 400 includes a U-shaped plate 410 bolted to the top of the workbench 100. The U-shaped plate 410 is arranged perpendicularly to the fixed limiting plate 340. An electric telescopic rod 420 is provided at the top of the U-shaped plate 410 and near the rear. The electric telescopic rod 420 is used to drive the strip pressure plate 430 to move up and down to press the copper strip. It is powered by an external power supply and controller. The movable rod of the electric telescopic rod 420 passes through the top of the U-shaped plate 410 and is fixedly connected to the strip pressure plate 430. A rubber pad can be provided at the bottom of the strip pressure plate 430. The strip pressure plate 430 limits the top of the copper strip. Together with the movable limiting plate 330 and the fixed limiting plate 340, it can ensure that the copper strip will not shift during cutting and ensure the quality of the cut copper strip.

[0036] The rear side of the strip pressure plate 430 is in contact with the front side of the fixed limiting plate 340, and the front side of the strip pressure plate 430 is in contact with the front side of the inner wall of the U-shaped plate 410, thereby improving the stability of the strip pressure plate 430.

[0037] The bottom of the movable limiting plate 330 and near the strip hole 110 are provided with a U-shaped clearance opening 331 for avoiding the strip pressure plate 430. The U-shaped clearance opening 331 is used to avoid interference between the movable limiting plate 330 and the strip pressure plate 430 when they move, so that the strip pressure plate 430 can move up and down smoothly and the movable limiting plate 330 can move back and forth smoothly.

[0038] A limiting vertical rod 431 is provided at the top of the strip pressure plate 430 and near the front side. The top of the limiting vertical rod 431 passes through the top of the inner wall of the U-shaped plate 410 to the outside. The limiting vertical rod 431 is used for vertical guidance of the strip pressure plate 430 and to ensure the pressing stability.

[0039] It should be noted that the cylinder 220, motor 250, electric telescopic rod 420, controller, and pneumatic drive system in this utility model are all general standard parts or parts known to those skilled in the art. Their structure and principle can be learned by those skilled in the art through technical manuals or conventional experimental methods. The specific connection means should refer to the working sequence of each electrical component in the above working principle to complete the electrical connection. The detailed connection means are well known in the art. The above mainly introduces the working principle and process, and will not explain the electrical control.

[0040] In this embodiment, the cutting mechanism with anti-deviation function is used by first laying the copper strip to be cut flat on the top of the workbench 100. By manually rotating the threaded rod 320 in the width limiting component 300, the movable limiting plate 330 is driven to move back and forth along the surface of the workbench 100, so that the distance between it and the fixed limiting plate 340 is adapted to the width of the copper strip, ensuring that the front and rear sides of the copper strip are respectively in contact with the opposite sides of the movable limiting plate 330 and the fixed limiting plate 340, thus completing the lateral limiting. Then, the electric telescopic rod 420 in the auxiliary positioning component 400 is activated to drive the strip pressure plate 430 to move downward and press the top of the copper strip. At the same time, the limiting vertical rod 431 provides vertical guidance for the strip pressure plate 430 to ensure stable pressing. Qualitative analysis; at this time, the U-shaped clearance 331 at the bottom of the movable limiting plate 330 provides clearance space for the strip pressure plate 430, avoiding interference between their movements; when the cutting assembly 200 is started, the cylinder 220 drives the moving seat 230 to move horizontally back and forth along the trajectory defined by the limiting longitudinal rod 270, driving the cutter 260 on the mounted vertical plate 240 to move from back to front, while the motor 250 drives the cutter 260 to rotate, cutting the copper strip; the bottom end of the cutter 260 avoids contact and wear with the worktable 100 through the strip hole 110; after the cutting is completed, the cylinder 220 resets, the electric telescopic rod 420 raises the strip pressure plate 430, the finished product is taken out, and the above process is repeated for the next batch of processing.
