[0029] like Figure 1 The pipe clamp 10 shown includes two clamping parts 101 . The two clamping parts 101 are formed by bending sheets. A fixing hole 102 is formed in the middle of the pipe clamp 10 .

[0030] Please refer to Figure 2-3 、 Figure 6As shown, the utility model provides a continuous stamping die for a pipe clamp 10, comprising an upper die base 20, a punch assembly, a die assembly, and a lower die base 70 arranged in sequence from top to bottom, the punch assembly comprising a trimming die group, a bending die group, and a cutting die group, the die assembly comprising a trimming pad insert 30, a bending pad insert 50, and a cutting pad insert 60 corresponding to the positions of the trimming die group, the bending die group, and the trimming die group. Specifically, a material sheet 80 enters from an external automatic conveying device, is punched on the trimming pad insert 30 in turn through the trimming die group, and a sheet body for forming the pipe clamp 10 is punched out on the material sheet 80; the sheet body is punched on the bending pad insert 50 through the bending die group to form the clamping part 101 of the pipe clamp 10, and finally is punched on the cutting pad insert 60 through the cutting die group to separate the formed pipe clamp 10 from the material sheet 80. The utility model adopts automatic continuous stamping to form the pipe clamp 10, which has high efficiency compared with manual stamping, and each pipe clamp 10 has high dimensional accuracy, meeting market demand.

[0031] Please refer to Figure 2-4 As shown, the trimming module includes a first punch and two second punches. The trimming pad insert 30 includes a first pad groove 301 and two second pad grooves 302. The first punch is positioned above the first pad groove 301, and the second punch is positioned above the second pad groove 302. Specifically, the first punch is used to punch the first pad groove 301 into the sheet 80, thereby forming a first through-hole. Subsequently, the two second punches are used to punch the two second pad grooves 302, thereby forming two second through-holes communicating with the first through-hole. This forms a sheet body on the sheet 80 for forming one side of the tube clamp 10. After these two punching operations, the sheet body for forming the tube clamp 10 is obtained. Furthermore, the male die assembly further includes a punching module, the female die assembly further includes a punching pad insert 40, the punching module includes a punching needle, the punching pad insert 40 includes a punching needle groove 401, the sheet moves with the material plate 80 to the top of the punching needle, and the punching needle punches the material plate 80 in the punching needle groove 401 to form a fixed hole 102 in the middle of the tube clamp 10.

[0032] Please refer to Figure 2-3 、 Figure 5 As shown, the bending die set includes several groups of punching blocks and several groups of shaping blocks, and the bending pad insert 50 includes several groups of punching pads 501 and several pads 502. Specifically, the punching blocks, punching pads 501, shaping blocks and pads 502 are respectively composed of four groups. First, the sheet connected to the material plate 80 is punched on the punching pads 501 in sequence by the four groups of punching blocks, and the two sides of the sheet are preliminarily bent; then, the bent sheet is punched on the pads 502 by the shaping blocks, and the bent part is preliminarily punched into the clamping portion 101. Under normal conditions, the pads 502 are placed on one side of the conveying direction of the material plate 80. When the shaping block is pressed down, the pads 502 are driven to extend into the bent sheet, so that the shaping block can press the sheet on the pads 502, i.e., the clamping portion 101 of the forming tube clamp 10.

[0033] Please refer to Figure 5 As shown, the cutting module includes a punching knife, and the cutting pad insert 60 includes a punching pad groove. The punching knife corresponds to the punching pad groove. The stamped tube clamp 10 is connected to the material plate 80. The punching knife is punched in the punching pad groove to separate the tube clamp 10 from the material plate 80 to form an independent product.

[0034] In addition, the die assembly further includes a plurality of guide blocks arranged in parallel. The material plate 80 moves along the guide blocks on both sides, which can prevent the material plate 80 from deviating from the track and ensure accurate stamping.

[0035] The above shows and describes the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely preferred examples of the present invention and are not intended to limit the present invention.
