DETAILED DESCRIPTION

[0017] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field belong to the scope of protection of the utility model.

[0018] like Figure 4 and 5 As shown, in the current prior art, there is no cantilever structure between the T-shaped punch 17 and the punch, the T-shaped punch 17 has a certain length, and is prone to breakage during hard stamping. The pressing layer 16 is also a whole piece. When the T-shaped punch 17 is stamping, the shortest distance between two adjacent T-shaped punches 17 is prone to breakage.

[0019] The utility model is different from the prior art, such as Figures 1 to 3 As shown, the punch comprises an upper die base 1 and a lower die base 2 which are arranged correspondingly. The upper die base 1 and the lower die base 2 are respectively provided with a punch 3 and a die 4. The die 4 has a cavity. A material 5 to be punched, i.e., a material strip, is horizontally placed in the cavity of the die 4. A pressing plate 6 for pressing the material strip is also provided in the cavity of the die 4.

[0020] A group of T-punches 7 are provided on the punch 3, and an elastic cantilever 9 is provided on the upper die base 1. In this embodiment, the group of T-punches 7 includes a base 71 and a plurality of T-punches 7 arranged in parallel on the base 71. The base 71 is a horizontal strip structure. Each T-punch 7 includes a transverse portion 72 and a vertical portion 73. The vertical portion 73 is vertically connected to the base 71. From the cross-sectional perspective, there is a certain gap between two adjacent T-punches 7. The relative vertical portions 73, the base 71 portion and the relative horizontal portions of the two adjacent T-punches 7 enclose an area with an opening, and the opening is located between the relative horizontal portions.

[0021] The elastic cantilever 9 includes an elastic member 91, a floating block 92 and a contour sleeve 93. A vertical mounting through hole 8 is opened on the upper die seat 1. The elastic member 91, the floating block 92 and the contour sleeve 93 are installed in the mounting through hole 8 from top to bottom in sequence. A sealing member is installed on the top of the mounting through hole 8 for capping. One end of the contour sleeve 93 is connected to the floating block 92, and the other end is connected to a pressing block 10 after passing through the mounting through hole 8 and the punch 3. The elastic member 91 adopts a spring, one end of the spring abuts against the sealing member, and the other end abuts against the floating block 92. The floating block 92, the contour sleeve 93 and the pressing block 10 are all coaxially connected by fasteners. The pressing block 10 is located between two adjacent T-punches 7, that is, a pressing block 10 is provided between each two adjacent T-punches 7. The pressing block 10 is located between two adjacent T-punches. In the area enclosed by 7 and the base 71, the pressing plate 6 is provided with an avoidance hole for the pressing block 10 to pass through, that is, the pressing plate 6 and the pressing block 10 jointly press the material 5, and there is a splicing line 15 between the pressing plate 6 and the pressing block 10 located in the avoidance hole. It should be noted that the splicing line 15 is located between the opposite ends of the transverse parts 72 of two adjacent T-punches 7, and the splicing line 15 is a horizontal line. Since the transverse part 72 has a certain thickness, the two ends of the splicing line 15 are between the end points of the part close to the pressing block 10 of the transverse line, thus forming a split pressing plate 6 and pressing block 10, so that when the T-punch 7 punches the material 5, there is a certain force buffer between the pressing plate 6 and the pressing block 10, which prevents the die 4 from being cracked due to the rigid pressing of the punch, causing damage to the mold.

[0022] In addition, the pressing block 10 and the pressing plate 6 are arranged at the same height relative to the material 5 to be punched, so that when the T-punch 7 punches the material 5, the pressure of the pressing plate 6 and the pressing block 10 on the material 5 can be as consistent as possible.

[0023] A first through hole 11 is provided at the bottom end of the punch 3, and one end of the T-punch 7 group is inserted into the first through hole 11. A fixing block 12 is also provided at the bottom end of the punch 3. A second through hole 13 coaxial with the first through hole 11 is provided on the fixing block 12. The T-punch 7 of the T-punch 7 group passes through the second through hole 13. A clamping block 14 is provided on the inner wall of the second through hole 13. A groove is provided on the peripheral wall of the T-punch 7. The clamping block 14 and the groove form a buckle, so that a buckle connection is formed between the clamping block 14 and the T-punch 7 group. The clamping block 14 is fixedly connected to the punch 3 by a fastener, which is convenient for disassembly and removal of the T-punch 7 group.

[0024] The present utility model is not limited to the above-mentioned optimal implementation mode. Anyone can derive other various forms of products under the inspiration of the present utility model. However, no matter what changes are made in the shape or structure, all those having the same or similar technical solutions as the present application fall within the protection scope of the present utility model.
