Description

Technical Field

[0001] This application relates to the field of die-cutting technology, and more specifically, to a die-cutting apparatus for a stamping production line. Background Technology

[0002] The die-cutting device in a stamping production line is a piece of equipment installed on the stamping production line for die-cutting materials. It can accurately cut materials according to specific shapes and sizes to meet production process requirements and ensure the forming accuracy and quality of stamped products.

[0003] In traditional die-cutting processes, materials are prone to displacement or deformation during cutting due to insecure fixation, resulting in rough cut edges, dimensional deviations, and reduced product yield. Furthermore, if the cut material cannot be promptly removed from the die, it can easily cause blockage, requiring frequent manual cleaning and causing material residue to wear down the die, reducing cutting accuracy, shortening die life, and increasing equipment maintenance costs and downtime.

[0004] In view of this, this application proposes a die-cutting device for a stamping production line. Utility Model Content

[0005] The purpose of this application is to provide a die-cutting device for a stamping production line, which solves the technical problems mentioned in the background art.

[0006] This application provides a die-cutting device for a stamping production line, including a die-cutting frame, a movable plate inside the die-cutting frame, a movable mechanism above the inside of the die-cutting frame, a pair of fixed frames that can be inserted into the lower part of the inside of the die-cutting frame, a die-cutting plate fixedly connected between the two fixed frames, an anti-blocking mechanism above the die-cutting plate, and a plurality of interconnected cutting tools fixedly inserted into the inside of the die-cutting plate.

[0007] The anti-blocking mechanism includes a connecting frame fixedly connected to the lower end face of the moving plate. An extension frame is slidably inserted into the lower end of the connecting frame. An installation plate is fixedly connected to the lower end face of the extension frame. The installation plate is fixedly connected to a plurality of limiting blocks corresponding to the cutting tool, and the limiting blocks extend into the cutting tool.

[0008] Optionally, limit posts are fixedly connected to both sides of the upper surface of the movable plate, and a limit frame is slidably sleeved on the outer wall of the limit post, and the limit frame is fixedly connected to the inner wall of the die-cutting frame.

[0009] Optionally, the moving mechanism includes a mounting bracket fixedly connected to both sides of the upper surface of the moving plate. The mounting bracket has a cam disk inside, and a rotating shaft is rotatably inserted into the lower end of the cam disk, with both ends of the rotating shaft extending into the mounting bracket.

[0010] Optionally, a rotating opening is provided through the interior of the upper end of the cam disk, and a rotating disk is rotatably connected inside the rotating opening.

[0011] Optionally, connecting rods are fixedly inserted into the upper part of the two rotating disks, and the two ends of the connecting rods are rotatably connected to the inner wall of the die-cutting frame. A motor is fixedly connected to the side wall of the die-cutting frame, and the output end of the motor is fixedly connected to the connecting rods.

[0012] Optionally, the internal fixed connection between the connecting frame and the extension frame is provided with multiple fixing springs.

[0013] One or more technical solutions provided in this application have at least the following technical effects or advantages:

[0014] This application utilizes a limiting block on the mounting plate in conjunction with a fixing spring to press the material down before cutting. During the cutting process, the spring force continuously applies pressure to prevent material displacement or deformation, ensuring neat and smooth cut edges and improving the quality of die-cut products. When the moving plate is lifted, the limiting block pushes the cut material out of the cutting blade, preventing material from clogging the blade. This not only reduces the frequency of manual blade cleaning but also prevents material residue from affecting subsequent cutting accuracy and blade lifespan, ensuring continuous and stable equipment operation.

[0019] The present application will be further described in detail below with reference to the accompanying drawings.

[0020] Reference Figures 1-3This application provides a die-cutting device for a stamping production line, including a die-cutting frame 1. A movable plate 3 is provided inside the die-cutting frame 1. A moving mechanism 6 is provided above the inside of the die-cutting frame 1. A pair of fixed frames 7 can be inserted into the lower part of the inside of the die-cutting frame 1. A die-cutting plate 8 is fixedly connected between the two fixed frames 7. An anti-blocking mechanism 9 is provided above the die-cutting plate 8. Multiple interconnected cutting blades 10 are fixedly inserted into the inside of the die-cutting plate 8. The anti-blocking mechanism 9 includes a connecting frame 901 fixedly connected to the lower end face of the movable plate 3. An extension frame 902 is slidably inserted into the lower end of the connecting frame 901. Multiple fixing springs 903 are internally fixedly connected to the extension frame 902. A mounting plate 904 is fixedly connected to the lower end face of the extension frame 902. Multiple limiting blocks 905 corresponding to the cutting blade 10 are fixedly connected to the mounting plate 904, and the limiting blocks 905 extend into the cutting blade 10. Through the cooperation of the limiting blocks 905 on the mounting plate 904 and the fixing springs 903, the material is pressed down before cutting. During the cutting process, the spring force continuously applies pressure to prevent the material from shifting or deforming during cutting, ensuring that the cutting edge is neat and smooth, and improving the quality of the die-cut product. When the moving plate 3 is lifted, the limiting blocks 905 push the cut material out of the cutting blade 10, avoiding material blockage of the blade. This not only reduces the frequency of manual cleaning of the blade, but also prevents material residue from affecting the subsequent cutting accuracy and blade life, ensuring the continuous and stable operation of the equipment.

[0021] Limiting posts 4 are fixedly connected to both sides of the upper surface of the movable plate 3. A limiting frame 5 is slidably sleeved on the outer wall of the limiting post 4, and the limiting frame 5 is fixedly connected to the inner wall of the die-cutting frame 1, which plays a good limiting role and makes the movement of the movable plate 3 more stable.

[0022] The moving mechanism 6 includes a mounting bracket 601 fixedly connected to both sides of the upper surface of the moving plate 3. The mounting bracket 601 has a cam disk 602 inside. A rotating shaft 603 is rotatably inserted into the lower end of the cam disk 602, and both ends of the rotating shaft 603 extend into the mounting bracket 601. A rotating opening 604 is opened through the upper end of the cam disk 602. A rotating disk 605 is rotatably connected inside the rotating opening 604. A connecting rod 606 is fixedly inserted into the upper part of the two rotating disks 605, and both ends of the connecting rod 606 are rotatably connected to the inner wall of the die-cutting frame 1. A motor 2 is fixedly connected to the side wall of the die-cutting frame 1, and the output end of the motor 2 is fixedly connected to the connecting rod 606. The limiting post 4 on the moving plate 3 cooperates with the limiting frame 5 on the inner wall of the die-cutting frame 1. The mounting bracket 601 and the rotating shaft 603 limit the cam disk 602, ensuring that the moving plate 3, cam disk 602 and other components remain stable during movement, reducing shaking and deviation. The stable motion trajectory ensures that the cutting tool 10 falls precisely each time, guaranteeing the consistency and accuracy of the die-cutting dimensions. This effectively avoids die-cutting errors caused by component shaking, improves product processing precision, and meets the requirements of high-precision die-cutting processes.

[0023] Working principle: The operator installs the die-cutting frame 1 onto the stamping production line. When in use, the motor 2 is started. The motor 2 drives the output end to rotate, which in turn drives the connecting rod 606 to rotate. Since the connecting rod 606 is fixedly inserted into one side of the rotating disk 605, the rotation of the connecting rod 606 causes the two outer walls of the rotating disk 605 to flip. The rotating disk 605 is installed in the rotating port 604 at one end of the cam disk 602. The rotating shaft 603 at the lower end of the cam disk 602 is fixedly connected to the mounting bracket 601 on the moving plate 3. The mounting bracket 601 and the rotating shaft 603 limit the cam disk 602. At the same time, the limiting posts 4 on both sides of the upper end face of the moving plate 3 are slidably inserted into the limiting frame 5 on the inner wall of the die-cutting frame 1. When the rotating disk 605 rotates one revolution, it causes the cam disk 602 to move up and down once, and the upper end of the cam disk 602 swings slightly. The rotation of the rotating disk 605 can drive the cam disk 602 to move up and down reciprocally.

[0024] The movement of the cam plate 602 drives the mounting frame 601 and the moving plate 3 to move back and forth synchronously. The movement of the moving plate 3 drives the connecting frame 901, the fixing frame 7 and the die-cutting plate 8 to move synchronously. Since the limiting block 905 on the mounting plate 904 passes through and extends the cutting tool 10, the movement of the connecting frame 901 drives the extension frame 902, the mounting plate 904 and multiple limiting blocks 905 to move synchronously. The limiting block 905 first presses down on the material to be die-cut. The moving plate 3 continues to move, and multiple fixing springs 903 retract. The extension frame 902 enters the connecting frame 901. The cutting tool 10 continues to move and directly cuts the material. Under the action of the elastic force of the fixing spring 903, the limiting block 905 always presses down on the material. When the moving plate 3 is lifted, the cutting tool 10 is lifted and detached from the material. The fixing spring 903 slowly unfolds as the moving plate 3 is placed on the platform, but the limiting block 905 remains in contact with the cutting material. As the cutting tool 10 moves, the limiting block 905 pushes out the cut material to prevent the cutting material from clogging the cutting tool 10 and affecting its later use. When the fixing spring 903 is fully unfolded, the connecting frame 901 moves upward, causing the extension frame 902, the mounting plate 904, and multiple limiting blocks 905 to move upward. The limiting block 905 detaches from the material, completing one die-cutting operation. The stamping production line will then push the material for the next die-cutting operation.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
