Description
Technical Field
[0001] This utility model relates to the field of leather product manufacturing technology, specifically a punching device for leather product manufacturing. Background Technology
[0002] Leather is a material obtained through a series of physical and chemical processing of animal hides. Its raw materials mainly come from animals, such as cattle, sheep, and pigs. In the production process, key steps include dehairing and tanning. Dehairing removes the hair from the animal hide, while tanning causes chemical changes in the hide, making it tough and less prone to decay. There are various tanning methods, such as vegetable tanning and chrome tanning. After tanning, the leather undergoes post-processing steps such as dyeing, fatliquoring, and finishing. Dyeing can give leather a variety of rich colors; fatliquoring can improve the softness and toughness of the leather; finishing includes sanding, embossing, and coating, which can make the surface of the leather more beautiful. Leather has many excellent properties, such as a certain degree of abrasion resistance and good flexibility. Its texture and touch are also relatively comfortable, so it is widely used to make leather shoes, leather clothing, leather bags, and other leather products.
[0003] In the current leather production field, the operation of punching devices has obvious defects. Typically, the leather is simply placed on the punching table without effective fixing and limiting measures. When punching, as the punching needle moves downward, the leather is not stabilized and is prone to positional deviation. This directly leads to inaccurate punching positions, failing to meet the requirements of precise production. Moreover, once the punching process is completed, during the upward return of the punch, the leather adheres tightly to the punch surface and is lifted up. At this point, the leather must be manually removed before the next round of punching can begin. This not only adds trouble to the operators and reduces practicality in actual use, but also greatly slows down the overall efficiency of punching, making it difficult to adapt to the pace of high-efficiency production. Therefore, we propose a punching device for leather product production. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0024] Please see Figure 1-5A punching device for leather product manufacturing includes a punching device 3, a workbench consisting of a table body 1 and a punching strip 4, and a clamping device consisting of a clamping member 2 and a motor 5. The main body of the workbench is the table body 1, and the punching device 3 is provided on the top side of the workbench. The bottom of the punching device 3 is fixedly connected to the table body 1 by an adapter bolt. The clamping device is provided inside the workbench, and the clamping member 2 is provided on the top of the clamping device and is slidably connected to the table body 1.
[0025] Furthermore, the end of the table body 1 facing away from the punching device 3 has a connecting plate 9 inside, and the top of the table body 1 has four sliding holes 6 at each of the four corners, with the sliding holes 6 corresponding to the connecting plate 9. The top of the table body 1 has four connecting holes 8 distributed symmetrically on the side, and the connecting holes 8 are fixedly connected to the bottom of the punching device 3 by matching bolts. The top of the table body 1 has a sliding groove 7 along the symmetrical center line, and the bottom center of the sliding groove 7 has a needle outlet 11. The inner side wall of the sliding groove 7 has four clamping parts 10 distributed axially. The connecting plate 9 of the table body 1 plays a fixed connection role to the motor 5, effectively ensuring the normal normal output of the motor 5.
[0026] Furthermore, the clamping component 10 consists of three parts: a base plate 13, an outer plate 14, and three equidistantly distributed springs 12. The middle component of the clamping component 10 is the spring 12. The two ends of the spring 12 are welded to the base plate 13 and the outer plate 14 respectively. The base plate 13 is welded to the inside of the table body 1, and the outer plate 14 slides inside the table body 1. The outer plate 14 has a protrusion 15 at the end opposite to the spring 12. The clamping component 10 effectively ensures the stable matching accuracy between the hole strip 4 and the punching needle after the punching size is adjusted, which greatly improves the accuracy and stability of punching.
[0027] Furthermore, the perforated strip 4 is slidably connected to the sliding groove 7. Both axial ends of the perforated strip 4 are provided with handles 18, and the side wall of the perforated strip 4 is provided with a set of clamping holes 17 distributed at equal intervals. The clamping holes 17 are engaged with the protrusions 15. The horizontal end face of the perforated strip 4 is provided with a set of through holes 16 of different sizes and at equal intervals. The perforated strip 4 is used with punching needles of different sizes to effectively ensure the adjustment of the punching size and improve the overall punching efficiency and quality.
[0028] Furthermore, the main body of the clamping device is the clamping component 2, and the bottom of the clamping component 2 is equipped with a motor 5. The top end of the motor 5 is fixedly connected to the connecting plate 9 by an adapter bolt, and the bottom threaded output shaft of the motor 5 is connected to the clamping component 2. The clamping device effectively ensures the stability of the overall clamping effect and ensures the punching accuracy of leather products in the punching process. After punching is completed, since the clamping device still holds the product, the punching needle will not take the leather product away when it rises, thus avoiding the problem of manually removing the leather and greatly improving punching efficiency and safety.
[0029] Furthermore, the clamping component 2 consists of three parts: a clamping plate 19, a mating plate 21, and four axisily symmetrically distributed sliding rods 20. The sliding rods 20 are welded to the four corners of the clamping plate 19 and the mating plate 21, and are slidably connected to the sliding holes 6. The top end of the clamping component 2 is the clamping plate 19, which has a working opening 22 in the center. One end of the clamping plate 19 corresponding to the sliding rod 20 is provided with an anti-slip layer 23. The bottom of the clamping component 2 is the mating plate 21, which has a threaded bushing 24 in the center. The threaded bushing 24 is connected to the threaded output shaft of the motor 5. The four axisily symmetrically distributed sliding rods 20 of the clamping component 2, together with the sliding holes 6, effectively ensure the stability of the lifting and clamping. The anti-slip layer 23 increases the friction with the leather product, further ensuring the clamping force and improving the punching accuracy and efficiency.
[0030] Working principle: The punching device for leather product production is correctly installed according to the diagram. Specifically, the punching device 3 is fixedly connected to the top side of the workbench, which consists of the table body 1 and the punching strip 4, using matching bolts. A clamping device, consisting of a clamping member 2 and a motor 5, is fixedly connected inside the workbench. When the punching device is in operation, a punching needle of the required size is selected, and the position of the punching strip 4 is adjusted so that the size of the through hole 16 on the punching strip 4 matches the size of the punching needle. The motor 5 of the clamping device controls the clamping member 2 to rise, placing the leather product on top of the table body 1. Once the part reaches the designated position, the output shaft of motor 5 reverses, causing clamping member 2 to press downwards, thus fixing the leather product and effectively preventing it from moving during the punching process. The punching device 3 is then activated, and the punching needle of the punching device 3 passes through the leather product, the through hole 16, and the top of the table body 1. After punching is completed, because the clamping device still holds the leather product, the punching needle will not take the leather product away when it rises, thus avoiding the problem of manually removing the leather and greatly improving punching efficiency and safety, thereby completing the punching process.
