[0002] At present, the communication industry is developing rapidly. The production cycle of product parts is short, the consumption is large, and the production capacity and quality precision are required to be high. For example, some products need to transfer steel sheets to tape for subsequent processing or use. The current process is: first use a stamping die to punch the steel sheet off the steel belt, and then use a glue sticking device to stick the steel sheet to the tape, and the processing efficiency is low. Utility Model Content

[0003] The utility model aims to provide a steel sheet stamping die to solve the technical problems in the background technology.

[0014] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0015] Specific embodiment 1: Please refer to Figure 1 and Figure 2 In an embodiment of the utility model, a steel sheet stamping die comprises an upper die 1 and a lower die 6. The upper die 1 is provided with a stamping punch 5. The upper die 1 comprises an upper die base 2, an upper die plate 3 and a stripper plate 4 from top to bottom. The stamping punch 5 is installed below the upper die plate 3 and its lower end passes through the stripper plate 4. The lower die 6 comprises, from bottom to top, a lower die base 7, a lower die spacer plate 8 and a lower mold plate 9. A first feed channel 701 is provided in the lower die base 7 along the vertical direction, a second feed channel 801 is provided in the lower mold spacer plate 8 along the vertical direction, and a third feed channel 1001 is provided in the lower mold plate 9. The first feed channel 701, the second feed channel 801 and the third feed channel 1001 are interconnected to form a conveying channel for conveying the film. The first feed channel 701 and the second feed channel 801 are both perpendicularly arranged to the bottom end surface of the lower die base 7, and the third feed channel 1001 is obliquely arranged in the lower mold plate 9. The transverse cross-sections of the first feed channel 701, the second feed channel 801 and the third feed channel 1001 are all rectangular structures. The top opening of the third feed channel 1001 is a discharge port, and the bottom opening of the first feed channel 701 is a feed port. The discharge port is on one side of the stamping punch 5 and on the output direction side of the steel sheet strip 12.

[0016] In the present application, the width W1 of the first feed channel 701D is the same as the width W2 of the second feed channel 801, the width W3 of the third feed channel 1001 is smaller than the width W2 of the second feed channel 801, the lengths of the first feed channel 701 and the second feed channel 801 are both longer than the length of the third feed channel 1001, and the third feed channel 1001 is located above the discharge port. Therefore, the length of the third feed channel 1001 is matched with the width of the film 13 actually used to achieve accurate attachment of the product. The first adjustment block 10 is detachably installed on the lower template 9, and the third feed channel 1001 is in the first adjustment block 10. The first adjustment block 10 can be detachably installed with the lower template 9 in an embedded manner or by a screw installation manner, which is convenient for adjustment and replacement according to material strips of different widths.

[0017] A guide block 11 is provided on the right side of the lower template 9, i.e., in the material discharging direction. The top of the guide block 11 is a downwardly inclined guide surface 1101. The inclined guide surface is convenient for outputting the glued material strip to the winding mechanism for winding.

[0018] See also Figure 3 When in use, the steel sheet strip 12 flows from the left side of the mold to the bottom of the stamping punch 5 for punching and cutting, and the glued film 13 passes from the bottom of the lower mold to the discharge port of the lower mold plate. The film is below the stripping plate. In this embodiment, the punching of the steel sheet is not a complete punching mode. Several connection points are reserved to allow the product to be on the strip. As the steel sheet strip 12 is continuously conveyed to the right, the steel sheet after punching and cutting will be conveyed to the position of the film 13. As the mold is closed, the product will be precisely pressed onto the film 13 to complete the gluing operation of the product, and then the winding mechanism can be used to wind up the bonded film.

[0019] Compared with the prior art, the steel sheet stamping die of the present application has a compact structure and layout, and a flow channel is arranged inside the die for conveying the tape film. After the steel sheet material is stamped, it is directly pressed and attached to the tape, which effectively realizes the gluing operation of the product while punching and cutting, ensures the accuracy of the steel sheet pasting position, greatly improves the overall work efficiency of the entire production chain, and can also reduce labor, equipment and other cost expenditures, thereby effectively ensuring the processing quality of the product.
