[0026] As shown in Figure 1 - Figure 3 The material belt fixing structure 1 provided by the present application is used for processing the material belt 30 by a punch press, the punch press includes an upper die and a lower die, the lower die includes the lifting plate 10, the lifting plate 10 is provided with the limiting groove 11, the limiting groove 11 is arranged along the extension direction of the lifting plate 10, the material belt 30 is provided with a plurality of buckling edges 31 along the extension direction thereof, the extension direction of the buckling edge 31 is arranged at an angle with the surface of the material belt 30, when the material belt 30 is placed on the lifting plate 10, the plurality of buckling edges 31 are inserted into the limiting groove 11.
[0027] The application sets a limiting groove 11 on the lifting plate 10, through stamping process or other suitable processing method, and a plurality of buckles 31 (which extend at an angle to the surface of the material belt 30) are protruded on the material belt 30. When the material belt 30 is placed on the lifting plate 10, the buckles 31 are inserted into the limiting groove 11, and the two sides of the buckles 31 are respectively supported on the two side walls of the limiting groove 11, which has a limiting effect on the buckles 31, and further has a limiting effect on the material belt 30. Such design can effectively limit the left and right swing of the material belt 30 during the punching process. During the stamping operation, the material belt 30 can maintain a relatively stable position, thereby ensuring the accuracy of the stamping position and avoiding size deviation and other quality problems of the punched product caused by the shaking of the material belt 30. Moreover, the buckle 31 setting method can effectively reduce the use of material belt 30 material and improve resource utilization. At the same time, the stable material belt 30 also reduces the need for additional manual intervention or equipment adjustment time to correct its position during the production process, which helps to improve the punching efficiency of the punch, makes the punching production more smooth and efficient, and improves the quality and efficiency of the punching production as a whole, which has good practical value.
[0028] In practical application, the design of the material belt fixing structure 1 also considers the convenience of operation. For example, the limiting groove 11 of the lifting plate 10 is designed to be detachable, which facilitates the replacement or adjustment of the size of the limiting groove 11 when needed to adapt to material belts 30 of different widths or thicknesses. In addition, the material selection of the limiting groove 11 is also carefully considered, and a wear-resistant material is usually used to ensure that the limiting groove 11 can maintain good working condition during long-time punching operation, reduce replacement frequency, and reduce maintenance cost.
[0029] The buckles 31 on the material belt 30 are designed in a shape that is easy to process, such as a rectangle or a trapezoid, which can simplify the processing process and reduce processing cost. At the same time, the size and shape of the buckle 31 are optimized to ensure that it can be tightly fitted when inserted into the limiting groove 11, which not only ensures the stability of the material belt 30, but also avoids damage to the material belt 30 caused by excessive fastening.
[0030] Further, a plurality of buckles 31 are arranged at intervals along the extension direction of the material belt 30.
[0031] Specifically, the spacing between adjacent buckles 31 can be adjusted according to the material and thickness of the material strip 30 and the punching frequency of the punch press to optimize the stress distribution and fixing effect of the material strip 30 during punching. In this way, it can ensure that the material strip 30 remains stable during high-speed punching, reducing production defects caused by movement or sliding of the material strip 30. In addition, adjusting the spacing of the buckles 31 can also adapt to different types of punching operations, whether it is thin or thick material, to ensure the accuracy and efficiency of punching. In design, the shape and size of the buckles 31 are also carefully designed to ensure that they can achieve quick positioning when inserted into the limiting groove 11, while avoiding excessive stress on the material strip 30, prolonging the service life of the material strip 30.
[0032] Further, the included angle between the buckle 31 and the surface of the material strip 30 is in the range of 30° to 60°.
[0033] Specifically, this design allows the buckle 31 to provide sufficient support when combined with the material strip 30, while maintaining the flatness of the material strip 30 surface to ensure that the buckle 31 has a stable limiting effect in the limiting groove 11 and is not easily removed from the groove. The optimization of the included angle ensures that the material strip 30 can uniformly withstand pressure during punching, avoiding damage to the material strip 30 caused by stress concentration. In addition, by adjusting the included angle, the stability and accuracy of punching can be further improved to ensure the quality of the punched parts. In actual application, the size of the included angle can be flexibly adjusted according to different punching requirements and material strip 30 characteristics to achieve the best punching effect.
[0034] Further, the end edge of the buckle 31 is provided with a rounded corner.
[0035] Specifically, to facilitate the smooth insertion of the buckle 31 into the limiting groove 11, while avoiding scratching or damaging the inner wall of the limiting groove 11 during insertion. The radius of the rounded corner is accurately calculated to ensure that the insertion performance of the buckle 31 is not affected, while minimizing wear on the limiting groove 11. In addition, the design of the rounded corner also takes into account the strength and toughness of the material to prevent cracking or breaking during long-term use. In actual production, this design significantly improves the durability and reliability of the material strip fixing structure 1, reducing maintenance costs and downtime.
[0036] To further enhance the durability of the clamping edge 31, the material selection of the clamping edge 31 is also carefully considered. Typically, a high-strength alloy material is chosen, which not only has good tensile strength and impact resistance, but also maintains its shape and size stability in long-term stamping cycles. The selection of such material ensures that the clamping edge 31 does not easily deform under repeated stress, thereby ensuring the long-term stable operation of the entire material belt fixing structure 1. At the same time, the corrosion resistance of the alloy material also greatly reduces the loss caused by environmental factors, prolonging the service life of the entire structure. In practical application, this design not only improves production efficiency, but also reduces long-term maintenance costs.
[0037] Further, the width of the clamping edge 31 is consistent with the width of the clamping edge 31.
[0038] Specifically, this design ensures that the clamping edge 31 can tightly fit with the material belt 30 during assembly, avoiding the problem of loosening or falling off due to size mismatch. In addition, the width of the clamping edge 31 is consistent with the width of the material belt 30, which also allows the entire structure to evenly disperse stress when subjected to tension, thereby improving the overall tensile strength and maintaining the edge of the clamping edge 31 against the wall of the limiting groove 11. In practical application, this design not only improves the stability and reliability of the material belt fixing structure 1, but also ensures the accuracy and safety in high-speed stamping operations.
[0039] Further, the clamping edge 31 has a double-layer structure, including a support layer on the inner side and a buffer layer on the outer side.
[0040] Specifically, the clamping edge 31 has a double-layer structure, including a rigid support layer on the inner layer and a flexible buffer layer on the outer layer. The rigid support layer ensures the structural strength and positioning stability of the clamping edge 31 within the limiting groove 11, while the flexible buffer layer reduces friction and collision damage between the clamping edge 31 and the limiting groove 11, and also serves as a buffer when the material belt 30 is subjected to slight vibration or impact force, preventing excessive shaking of the material belt 30.
[0041] The double-layer structure design also has good adaptability, which can adapt to material belts 30 of different thicknesses and materials. The rigid support layer on the inner layer provides the necessary rigidity to the entire clamping edge 31, ensuring that the clamping edge 31 does not deform or damage under high-speed operation and heavy load conditions. The flexible buffer layer on the outer layer absorbs and disperses the vibration and impact generated by the material belt 30 during operation, thereby protecting the material belt 30 from damage and prolonging the service life of the material belt 30. In addition, this double-layer structure design also facilitates installation and replacement, improving the convenience of maintenance and further reducing production costs.
[0042] Further, the thickness of the clamping edge 31 gradually decreases in the direction of its insertion into the limiting groove 11.
[0043] Specifically, the thickness of the clamping edge 31 gradually decreases along the direction of its insertion into the limiting groove 11, forming a wedge-like structure. This facilitates the smooth insertion of the clamping edge 31 into the limiting groove 11. After insertion, the wedge-shaped structure allows for a self-locking effect between the clamping edge 31 and the limiting groove 11, enhancing the material strip 30's resistance to displacement during the stamping process. Even under significant lateral forces, the material strip 30 remains securely fixed.
[0044] This wedge design not only simplifies the installation process but also enhances the precision of the fit between the clamping edge 31 and the limiting groove 11. In practical applications, this structure effectively reduces the risk of loosening due to improper installation or long-term use, ensuring the stability and accuracy of the punch during continuous operation. Additionally, the self-locking effect of the wedge-shaped clamping edge 31 reduces the reliance on additional fixing devices, thereby lowering material and maintenance costs. In terms of design, the thickness variation of the wedge-shaped clamping edge 31 requires precise calculation to ensure consistent performance and durability under various working conditions.
[0045] Further, the surface of the clamping edge 31 is provided with anti-skid lines.
[0046] Specifically, the surface of the clamping edge 31 is provided with anti-skid lines, and the shape and depth of the anti-skid lines are designed according to the friction coefficient requirements between the material strip 30 and the limiting groove 11. This design enhances the friction force of the clamping edge 31 within the limiting groove 11, further improving the material strip 30's fixation reliability and preventing relative sliding between the clamping edge 31 and the limiting groove 11 during the stamping process.
[0047] The anti-skid lines are carefully designed to ensure consistent friction effects in various working environments. These lines are not only evenly distributed along the length of the clamping edge 31 but also optimized in the width direction to accommodate material strips 30 of different thicknesses and materials. Additionally, the material selection of the anti-skid lines takes into account wear resistance and corrosion resistance to ensure that the lines do not fail due to wear or chemical reactions over time. Through these designs, the stability of the material strip 30 during the stamping process is significantly improved, thereby enhancing the efficiency and safety of the entire punch operation.
[0048] Further, the number of limiting grooves 11 is multiple, and the multiple limiting grooves 11 are arranged at intervals, and one or more clamping edges 31 are inserted into one limiting groove 11.
[0049] Specifically, the size and shape of each limiting groove 11 are precisely calculated to accommodate different specifications of the material belt 30. The inner wall of the limiting groove 11 is designed as a smooth surface to reduce the frictional resistance of the material belt 30 when inserted and removed, while ensuring that the limiting groove 11 can provide sufficient support force when the material belt 30 is subjected to stamping. In addition, the material selection of the limiting groove 11 also considers its durability and adaptability to the stamping process, ensuring that it does not deform or damage during long-term use. Through this design, the positioning of the material belt 30 during the stamping process is more accurate, thereby improving the quality of the stamped parts and production efficiency.
