[0028] Example

[0029] Please refer to the instruction manual Figure 1 and 3 As shown in the instruction manual, Figure 1 and 3 The utility model is a thin material strip reinforcement stamping die, which is used in conjunction with a press machine for Figure 6 The strength of the overlap on the metal thin material strip 8 shown is enhanced, and the thin material strip reinforcement stamping die includes an upper die set and a lower die set corresponding to the upper and lower parts. The upper die set is composed of an upper die base 1, an upper pad 2, an upper splint 3, a stop plate 4 and an upper stripping plate 5 from top to bottom. Specifically, the upper pad 2 is fixedly connected to the bottom surface of the upper die base 1 by bolts, and the upper template 1 is installed on the bottom of the slider of the press by bolts (not shown here). The slider of the press can drive the upper template 1 to move up and down, and the upper splint 3 is fixedly connected to the bottom surface of the upper pad 2 by bolts; refer to the appendix of the instruction manual. Figure 1 and 3 As shown, the stop plate 4 is arranged below the bottom of the upper clamping plate 3 and can be moved up and down. Figure 1 and 3The top of the fixing plate 31 is fixed with the fixing plate 32 so as to prevent the fixing plate 32 from sliding upward and downward, thereby preventing the fixing plate 32 from sliding upward and downward. Figure 1 and Figure 2 As shown, the bottom of the upper die base 1 has a vertically arranged spring 6, and the top of the spring 6 is fixedly installed on the bottom of the upper die base 1. The spring 6 is a nitrogen spring, and its length is longer than the combined height of the upper pad 2 and the upper splint 3. In order to facilitate the installation of the spring 6, the upper pad 2 and the upper splint 3 are provided with a connecting hole that is connected up and down. The spring 6 is inserted into the connecting hole, and the lower end of the spring 6 passes through the upper pad 2 and the upper splint 3 through the connecting hole and extends downward below the bottom of the upper splint 3. The lower end of the spring 6 conflicts with the top surface of the stop plate 4; the upper stripping plate 5 is fixedly connected to the bottom of the upper splint 3 by bolts, and the upper stripping plate 5 can move synchronously up and down with the stop plate 4; in order to facilitate stamping and forming, as Figure 2 As shown, the bottom of the upper stripping plate 5 is provided with an upward concave groove 51, and the cross section of the groove 51 is an arc-shaped structure; Figure 1 and 3 As shown, the lower die set consists of a lower die base 11, a lower pad 10 and a lower template 9; specifically, the lower pad 10 is fixedly connected to the top of the lower die base 11 by bolts, and the lower template 9 is fixedly connected to the top of the lower pad 10 by bolts. The lower template 9 corresponds to the upper stripping plate 5 in the upper and lower directions, and a punch 7 is provided on the lower template 9. Specifically, as shown in FIG. Figure 1 As shown, the top surface of the lower template 9 is horizontal, and correspondingly, the bottom surface of the upper stripping plate 5 is also horizontal. The lower template 9 is provided with an embedding groove 91, and the punch 7 is embedded in the embedding groove 91, which is convenient for disassembly and assembly; Figure 4 and 5 As shown, the top of the punch 7 has an upwardly protruding forming portion 71, and the forming portion 71 at the top of the punch 7 protrudes above the top surface of the lower template 9. The cross-section of the forming portion 71 is a semicircular structure, which corresponds to the groove 51 above and below and is nested in the upper and lower parts. In order to facilitate material removal, a transition portion 72 with an arc-shaped structure is provided between the bottom side of the forming portion 71 and the horizontal plane of the top surface of the punch 7.

[0030] Its specific working principle is as follows: When the mold is closed, the Figure 1 and 3 As shown, when the upper die set moves downward, the spring 6 applies a downward force to the stop plate 4, and the stop plate 4 drives the upper stripping plate 5 and presses the thin material strip 8 placed on the lower template 9. The overlap 82 on the thin material strip 8 is placed on the top of the punch 7. The upper die set continues to move downward and punches the thin material strip 8 through the upper and lower matched punches 7 and the groove 51. When the movement is completed until the mold is completely closed, the required stamping action is completed, and the punching ribs on the overlap 82 on the thin material strip 8 are realized through the upper and lower matched punches 7 and the groove 51, as shown in FIG. Figure 7 As shown, a raised rib 81 is formed on the overlap 82 to enhance the strength of the thin material strip 8 on the overlap 82; when the mold is opened, the attached Figure 1 As shown, when the upper mold assembly moves upward, the spring 6 separates from the stop plate 4 and the stripper plate 5, loosening the thin material strip 8. At this time, one stamping movement cycle of the mold is completed, and then the thin material strip 8 is pushed forward to punch the parts of the overlapping edge 82 of the thin material strip 8 where the ribs 81 need to be punched.

[0031] This thin material strip reinforcement stamping die adds ribs 81 on the overlapping edge 82 of the thin material strip 8 by stamping, thereby reinforcing the overlapping edge 82 on the thin material strip 8, enhancing the strength of the thin material strip 8, ensuring smooth feeding of the thin material strip 8 on the punching die, solving the problem of thin material strip being weak and continuous feeding not being smooth, and ensuring production efficiency while ensuring smooth production and processing of the punching die.

[0032] It should be emphasized that the above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Those skilled in the art will readily appreciate that the present invention is susceptible to various modifications and variations. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
