Description

Technical Field

[0001] This utility model relates to the field of die-cutting technology, specifically to a die-cutting clamping device. Background Technology

[0002] Die-cutting is a processing technique that precisely cuts, indents, or shapes materials using a die. It is commonly used for mass production of workpieces of specific shapes. However, when die-cutting materials with some elasticity, such as elastic thin films, the die-cutting blade can pull on the workpiece during the cutting process, easily causing deformation. This can lead to significant dimensional errors in the final die-cut material. Therefore, it is necessary to use an auxiliary device to fix the workpiece during the die-cutting process to reduce the large changes caused by external pulling forces. To address this, a die-cutting clamping device is proposed. Utility Model Content

[0003] The purpose of this invention is to provide a die-cutting clamping device to solve the problem that the die-cutting blade pulls on the workpiece during the cutting process, which can easily cause deformation of some materials and lead to large errors in the size of the die-cut materials in the later stage.

[0004] To achieve the above objectives, this utility model specifically adopts the following technical solution: A die-cutting clamping device includes two side support plates, a curved plate is fixedly installed between the two side support plates, and a support plate is fixedly installed on one side of each of the two side support plates. A square hole is opened on the side wall of the support plate, a connecting mechanism is slidably inserted into the square hole, and a clamping mechanism is provided on one side of the connecting mechanism.

[0005] Preferably, the connecting mechanism includes a square guide rod, one end of which is slidably inserted into a square hole, and a connecting plate is fixedly installed on one end of the square guide rod.

[0006] Preferably, the clamping mechanism includes a clamping plate, one side of which is fixedly mounted on the other end face of the square guide rod, an elastic element is fixedly mounted on the upper side wall of the clamping plate, and the other end of the elastic element is fixedly mounted on a support plate.

[0007] Preferably, the elastic element includes a support cylinder, one end of which is fixedly installed on the side wall of the pressure plate, and a return spring is fixedly installed on the inner side wall of the support cylinder. A connecting rod is fixedly installed on the other end of the return spring, one end of which is slidably inserted into the support cylinder, and the other end of which is fixedly installed on the support plate.

[0008] Preferably, a pressure protective pad is fixedly installed on the lower side wall of the pressure plate, and the pressure protective pad is made of silicone material.

[0009] Preferably, the connecting plate is arranged in a U-shape, and the upper end of the connecting plate is provided with multiple assembly holes, and the bottom sidewalls of the two side support plates are provided with positioning holes.

[0010] The beneficial effects of this utility model are as follows: 1. In this utility model, the device is fixedly installed on the die-cutting machine by means of components such as a connecting plate, a square guide rod, and a pressing plate, and by means of a side support plate. The connecting plate is also fixedly installed on the blade holder of the die-cutting blade. When cutting flexible materials such as films, the blade holder will also push the connecting plate and the square guide rod to move during the die-cutting blade's downward cutting process. The square guide rod will push the pressing plate downward to move, thus using the pressing plate to press the die-cutting workpiece, thereby avoiding excessive pulling of the workpiece by the shearing force of the die-cutting blade. This can prevent the workpiece from undergoing large deformation, which would lead to dimensional errors and improve the dimensional accuracy of the workpiece after die-cutting.

[0017] like Figure 1-3 As shown, a die-cutting clamping device includes two side support plates 1. Positioning holes 3 are provided on the bottom sidewalls of both side support plates 1, allowing for easy assembly with a die-cutting machine. A curved plate 2 is fixedly installed between the two side support plates 1, and a support plate 4 is fixedly installed on one side of each side support plate 1. A square hole 5 is provided on the sidewall of the support plate 4.

[0018] A connecting mechanism is slidably inserted into the square hole 5. The connecting mechanism includes a square guide rod 6. One end of the square guide rod 6 is slidably inserted into the square hole 5, and a connecting plate 7 is fixedly installed on one end of the square guide rod 6. The connecting plate 7 is U-shaped, and multiple assembly holes are opened at the upper end of the connecting plate 7. The device can be easily installed on the die holder of the die-cutting equipment by using the connecting plate 7 and the assembly holes.

[0019] A clamping mechanism is provided on one side of the square guide rod 6. The clamping mechanism includes a clamping plate 8. One side of the clamping plate 8 is fixedly installed on the other end face of the square guide rod 6. A clamping protective pad 10 is fixedly installed on the lower side wall of the clamping plate 8. The clamping protective pad 10 is made of silicone. The clamping protective pad 10 can buffer and protect the workpiece that needs to be clamped, thereby avoiding excessive clamping by the clamping plate 8 and causing damage to the workpiece.

[0020] An elastic element 9 is fixedly installed on the upper side wall of the pressure plate 8. The elastic element 9 includes a support cylinder 903. One end of the support cylinder 903 is fixedly installed on the side wall of the pressure plate 8, and a return spring 902 is fixedly installed on the inner side wall of the support cylinder 903. A connecting rod 901 is fixedly installed on the other end of the return spring 902.

[0021] One end of the connecting rod 901 is slidably inserted into the support cylinder 903, and the other end of the connecting rod 901 is fixedly installed on the support plate 4. The reset spring 902, in conjunction with the connecting rod 901, can easily assist in pulling the support cylinder 903 and the pressure plate 8 upward, thereby facilitating the tool holder to pull the pressure plate 8 upward in a stable manner.

[0022] In summary: When installing this device, the side support plate 1, along with the positioning bolts and positioning holes 3, can be used to fix the device on the die-cutting machine. The connecting plate 7, along with the assembly holes, can be fixed on the die holder of the die-cutting blade. When cutting flexible materials such as films, the die holder will also push the connecting plate 7 and the square guide rod 6 to move during the die-cutting blade's downward movement. The square guide rod 6 will then push the pressing plate 8 downward, allowing the pressing plate 8 and the pressing protective pad 10 to press the die-cutting workpiece firmly, thus preventing the shearing force of the die-cutting blade from excessively pulling the workpiece. After die-cutting is completed, the die holder will again pull the pressing plate 8 upward via the square guide rod 6. At the same time, the elastic element 9 will also assist in moving the pressing plate 8 upward.

[0023] The foregoing description enables those skilled in the art to implement or use this invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of this invention.
