[0026] like Figures 1-2As shown, one embodiment of this utility model is: the bending and punching composite mold includes an upper mold 2 disposed above the interior of the mold frame 1 and a lower mold 3 disposed below the interior of the mold frame 1. The upper mold 2 and the lower mold 3 are fastened together for bending the workpiece. It also includes a punching device 4 and a follower device 5. The punching device 4 is horizontally disposed at the bottom of the mold frame 1 corresponding to the lower mold 3 and is slidably connected to the upper mold 2 and the lower mold 3 respectively. The follower device 5 is elastically disposed on the rear side inside the mold frame 1 and abuts against the upper mold 2 and is rollably connected to the follower device 5. When the upper mold 2 moves to the side of the lower mold 3, it drives the follower device 5 to move, thereby driving the punching device 4 to move to the side of the lower mold 3 to punch holes in the workpiece.

[0027] During operation, the workpiece is placed in the lower die 3, which remains stationary. The upper die 2 moves downward and first contacts the lower die 3 to bend the workpiece. During the descent, the upper die 2 contacts the follower device 5, which pushes the follower device 5 downward. The follower device 5 drives the punching device 4 to move to one side of the lower die 3 to perform side punching on the workpiece.

[0028] This application integrates bending and punching into one mold. The movement of the upper mold drives the follower device, which in turn drives the punching device, completing the bending and punching of the workpiece in one go. Only one mold is needed to complete the work of the original two molds, avoiding the problem of product size deviation during multiple processing, improving work efficiency and reducing production costs.

[0029] In one embodiment, such as Figure 3 As shown, the punching device 4 includes a slide rail 41, a slide block 42, a punching die 43, a guide rod 44, a first spring 45, and a roller 46.

The punching die 43 is arranged on the slide block 42 and is slidably connected to the upper die 2 and the lower die 3 respectively. The guide rod 44 is arranged at one end of the slide block 42 and passes through the mold frame 1 and is slidably connected to the mold frame 1. The first spring 45 is sleeved on the guide rod 44 outside the mold frame 1 to keep the slide block 42 away from the lower die 3. The roller 46 is arranged on the rear side of the slide block 42 and is slidably connected to the follower device 5.

[0030] When the upper die 2 moves downward, it pushes the follower device 5 to move downward. The follower device 5 drives the slide block 42 to move along the slide rail 41 to the side of the lower die 3 through the roller 46, thereby driving the punching die 43 to punch the workpiece. At the same time, the first spring 45 is compressed. After the upper die 2 is reset, the first spring 45 drives the slide block 42 to reset through the guide rod 44.

[0031] In one embodiment, such as Figure 4As shown, the follower device 5 includes a guide post 51, a follower plate 52, and a second spring 53.

The follower plate 52 is provided with a drive structure 54, and the roller 46 is tactilely connected to the drive structure 54.

[0032] When the upper mold 2 moves downward, it pushes the follower plate 52 to move downward along the guide post 51, and the drive structure 54 and the roller 46 come into contact, pushing the slide 42 to move. At the same time, it compresses the second spring 53. When the upper mold 2 is reset, the second spring 53 pushes the follower plate 52 to reset.

[0033] In one embodiment, such as Figure 4 As shown, the drive structure 54 includes a slot on the follower plate 52, and a roller 46 is located in the slot and is tactilely connected to the slot. When the follower plate 52 moves downward, the roller 46 rolls along the slot, driving the slide block 42 to move along the slide rail 41 to the side of the lower mold 3.

[0034] In one embodiment, the drive structure 54 includes an inclined surface disposed at the bottom of the follower plate 52, the inclined surface being tactilely connected to the roller 46; when the follower plate 52 moves downward, the roller 46 rolls along the inclined surface, driving the slide block 42 to move along the slide rail 41 to the side of the lower mold 3.

[0035] In one embodiment, such as Figure 2 As shown, a control arm 21 is provided on one side of the upper mold 2. The control arm 21 abuts against the follower plate 52. When the upper mold 2 moves downward, the control arm 21 pushes the follower plate 52 to slide along the guide rod 44.

[0036] In one embodiment, such as Figure 5 As shown, the upper die 2 has a punching groove 22 at the position corresponding to the punching die 43. The punching die 43 and the punching groove 22 are slidably connected. The position of the punching groove 22 is the position where the workpiece needs to be punched.
