Description

Technical Field

[0001] The utility model relates to the technical field of die-cutting machines, in particular to a position fixing device for a die-cutting machine. Background Art

[0002] A die-cutting machine, also known as a cutting machine or a numerical control punching machine, is mainly used for die-cutting (full cut, half cut), indentation, hot stamping, and laminating operations of some non-metallic materials, self-adhesive labels, mobile phone pads, paper boxes, greeting cards, etc. The die-cutting machine uses steel knives, metal molds, steel wires (or templates engraved from steel plates), and applies a certain pressure through an impression plate to cut the printed matter or cardboard into a certain shape. It is an important device for post-printing packaging processing and forming, and is also a high-efficiency, safe, and high-quality molding device.

[0003] Currently, when the existing die-cutting machines process workpieces, clamping mechanisms are required to fix and limit the positions of the workpieces to ensure stability during processing and to ensure processing accuracy. However, in specific use, most of the clamping mechanisms use electric telescopic rods in cooperation with clamping plates to fix and limit the side walls of the workpieces. For some workpieces with uneven outer walls, the contact area between the clamping plate and their outer walls is small, resulting in insufficient clamping force and the inability to effectively fix the workpieces. The workpieces may shift or rotate during the processing, affecting the stability and accuracy of the processing. Therefore, it is necessary to redesign a position fixing device for a die-cutting machine to address the above problems. Summary of the Utility Model

[0004] The purpose of the utility model is to solve the deficiencies existing in the prior art and to propose a position fixing device for a die-cutting machine.

[0005] To achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A position fixing device for a die-cutting machine includes a bottom plate. The upper end surface of the bottom plate is fixedly connected with a side plate. The outer wall of the side plate is L-shaped. The side plate is connected with a punching block through a telescopic mechanism. The upper end surface of the bottom plate is provided with a sliding groove. Two groups of sliders are slidably connected in the sliding groove. The upper end surfaces of the two groups of sliders are both fixedly connected with sliding plates. Two groups of rotating cylinders are installed on the upper end of the sliding plates. One group of the two groups of rotating cylinders rotates on the upper end surface of the sliding plate, and the other group of rotating cylinders is fixed on the upper end surface of the sliding plate. The two groups of rotating cylinders are connected to each other through a fiber cloth.

[0007] Preferably, the telescopic mechanism includes an electric telescopic rod fixedly connected to the upper end surface of the side plate. The telescopic end of the electric telescopic rod is fixedly connected with the punching block.

[0008] Preferably, a double-headed threaded rod is rotatably connected to the inner wall of the sliding groove. The two groups of sliders are both threadedly connected to the threaded sections of the double-headed threaded rod.

[0009] Preferably, the outer walls on both sides of the two groups of sliders are flat, and the outer walls on both sides of the two groups of sliders are in close contact with the inner wall of the chute.

[0010] Preferably, connecting plates are fixedly connected to the outer walls on both sides of the punching block, a sliding rod is slidably connected to the outer wall of the connecting plate, and a clamping plate is fixedly connected to the end of the sliding rod.

[0011] Preferably, a limiting block is fixedly connected to the end of the sliding rod away from the clamping plate, and the radius dimension of the limiting block is larger than the radius dimension of the sliding rod.

[0012] Preferably, a spring is sleeved on the outer wall of the sliding rod, one end of the spring is fixedly connected to the connecting plate, and the other end of the spring is fixedly connected to the limiting block.

[0013] Preferably, a servo motor is fixedly connected to the side wall of the bottom plate, and the end of the output shaft of the servo motor is coaxially and fixedly connected to a double-headed threaded rod.

[0014] Preferably, micro DC motors are fixedly connected to the lower end surfaces of the two groups of sliding plates, and the micro DC motors are coaxially and fixedly connected to the adjacent rotating cylinders.

[0015] The utility model has the following beneficial effects:

[0016] 1. By adjusting the positions of the sliders and the sliding plates, the fiber cloth can fully and tightly fit the outer wall of the workpiece. When dealing with uneven or complex-shaped outer walls of the workpiece, the fiber cloth can still achieve a uniform clamping effect. By adjusting the tension of the fiber cloth, it is ensured that the fiber cloth will neither loosen nor be overly tightened during the clamping process, thereby improving the clamping stability of the workpiece and the accuracy during the processing, and avoiding the problems of insufficient clamping force and easy displacement of the workpiece when facing irregular workpieces.

[0017] 2. By designing the combined structure of the punching block, the connecting plate, the sliding rod and the clamping plate, and setting a spring and a limiting block on the sliding rod, a buffering effect is provided when the clamping plate contacts the workpiece, avoiding damage to the surface of the workpiece caused by excessive clamping force. It not only improves the flexible adaptability of the clamping, but also protects the surface of the workpiece, reducing possible surface indentations or damages during the processing.

The two groups of rotary drums 11 are connected to each other through a fiber cloth 12;

[0025] The fiber cloth 12 can well adapt to workpieces of various shapes, including workpieces with uneven outer walls. By adjusting the position of the fiber cloth 12, it can be ensured that the fiber cloth is closely attached to the outer wall of the workpiece, realizing effective clamping. And by rotating one of the two groups of rotary drums 11, the tension degree of the fiber cloth 12 can be adjusted to achieve the best clamping effect.

[0026] The telescopic mechanism includes an electric telescopic rod 3 fixedly connected to the upper end surface of the side plate 2, the telescopic end of the electric telescopic rod 3 is fixedly connected with the punching block 4, a double-headed threaded rod 6 is rotatably connected to the inner wall of the chute 5, the two groups of slide blocks 8 are both threadedly connected to the threaded sections of the double-headed threaded rod 6, the outer walls of the two groups of slide blocks 8 are both flat, and the outer walls of the two groups of slide blocks 8 are both in close contact with the inner wall of the chute 5; the double-headed threaded rod 6 can flexibly adjust the positions of the two groups of slide blocks 8.

[0027] Both outer walls of the punching block 4 are fixedly connected with connecting plates 13. A sliding rod 14 is slidably connected to the outer wall of the connecting plate 13. A clamping plate 15 is fixedly connected to the end of the sliding rod 14. A limiting block 16 is fixedly connected to the end of the sliding rod 14 away from the clamping plate 15. The radius of the limiting block 16 is larger than the radius of the sliding rod 14. A spring 17 is sleeved on the outer wall of the sliding rod 14. One end of the spring 17 is fixedly connected with the connecting plate 13, and the other end of the spring 17 is fixedly connected with the limiting block 16; the clamping plate 15 can further clamp and fix the position of the workpiece, and the spring 17 provides a certain buffering effect to ensure that when the clamping plate 15 contacts the workpiece, force can be applied evenly, avoiding damage to the surface of the workpiece, and at the same time improving the flexible adaptability of the clamping.

[0028] A servo motor 7 is fixedly connected to the side wall of the bottom plate 1. The end of the output shaft of the servo motor 7 is coaxially and fixedly connected with the double-headed threaded rod 6. Micro DC motors 9 are fixedly connected to the lower end surfaces of the two groups of sliding plates 10. The micro DC motors 9 are coaxially and fixedly connected with the adjacent rotating cylinders 11.

[0029] In the present utility model, when the device is specifically used: operate the servo motor 7 to drive the double-headed threaded rod 6 to rotate, adjust the positions of the two groups of sliders 8 in the sliding grooves 5, and then adjust the position of the sliding plate 10, so that the fiber cloth 12 can fully contact the outer wall of the workpiece. Subsequently, through the micro DC motor 9, drive a rotating cylinder 11 to start rotating, and adjust the tension of the fiber cloth 12 by the rotation of the rotating cylinder 11 until the fiber cloth 12 tightly wraps the outer wall of the workpiece, achieving a uniform clamping effect, ensuring that the fiber cloth 12 is neither loose nor overly tight when clamping the workpiece.

[0030] Then start the electric telescopic rod 3 to push the punching block 4 towards the workpiece. The punching block 4 drives the clamping plate 15 to move through the connecting plates 13 and sliding rods 14 on both sides of it. When the clamping plate 15 contacts the other side of the workpiece, the spring 17 starts to provide a buffering effect to ensure that the clamping plate 15 applies force evenly, further stabilizing the position of the workpiece, avoiding damage to the surface of the workpiece, and the limiting block 16 limits the excessive movement of the sliding rod 14 during this process, ensuring that the clamping plate 15 applies force within a reasonable range.

[0031] When it is confirmed that the workpiece has been firmly fixed by the fiber cloth 12 and the clamping plate 15, and each component is in the preset position, at this time the workpiece should be in a stable state and will not displace or rotate during the processing.

[0032] With the help of the provided punching block 4 for die-cutting the workpiece, since the workpiece has been firmly fixed, the entire processing process will have high stability and precision. Through the above process, it can ensure that the workpiece remains stable during the processing, adapt to workpieces of different shapes, improve the processing precision, and avoid damage to the workpiece.

[0033] The above are only the preferred specific embodiments of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution of the present utility model and its inventive concept, makes equivalent substitutions or changes, and should be covered within the protection scope of the present utility model.
