A pressure member is fixedly connected to the lower end of the fixed posts. The surface of the pressure member has a through hole for the punch head to pass through. In use, the hinge component is placed on the punching die. When the rotating disk moves to the punching station, the lower cylinder frame and the fixed posts move, so that the pressure member presses on the hinge component first. Then, the punching cylinder drives the punch head to move, passing through the through hole on the surface of the pressure member, and performs the punching operation in conjunction with the punching die. After punching, the punch head resets first, and then the pressure member resets, which reduces the phenomenon of the hinge component being lifted up.

[0021] Please see Figures 1-5 This utility model provides a technical solution: a hardware hinge punching device, including a body 1 and a punching device 5. A rotating disk 2 is provided on the surface of the body 1, and a plurality of punching molds 4 are installed on the surface of the rotating disk 2. A bracket 3 is fixedly connected to the surface of the body 1, and the punching device 5 is provided on the surface of the bracket 3.

[0022] Specifically, the stamping device 5 includes a pressing cylinder 51, which is fixed on the surface of the bracket 3. The output end of the pressing cylinder 51 is fixedly connected to a frame 52. The inner wall of the frame 52 is fixedly connected to a punching cylinder 55. The output end of the punching cylinder 55 is fixedly connected to a punching head 56. The lower surface of the frame 52 is fixedly connected to two fixing posts 53. The lower end of the fixing posts 53 is fixedly connected to a pressing member 54. The surface of the pressing member 54 has a through hole for the punching head 56 to pass through.

[0023] In this implementation scheme: When in use, the processed hinge component is placed on the punching die 4. When the rotating disk 2 is driven to the punching station, the frame 52 and the fixed column 53 of the pressing cylinder 51 move, so that the pressing part 54 presses on the hinge component first. Then, the punching cylinder 55 drives the punching head 56 to move through the through hole on the surface of the pressing part 54 and perform punching operation in conjunction with the punching die 4. After punching is completed, the punching head 56 resets first, and then the pressing part 54 resets, which can reduce the phenomenon of the hinge component being lifted up.

[0024] Specifically, two guide rods 57 are fixedly connected to the surface of the frame 52. The guide rods 57 are slidably connected to the inner wall of the bracket 3. A positioning ring 58 is fixedly connected to the surface of the guide rods 57. When the pressing cylinder 51 drives the pressing component 54 to press down, the guide rods 57 can guide, and the positioning ring 58 can position the pressing stroke to ensure that the pressing component 54 is stably pressed on the hinge component.

[0025] Specifically, the pressure member 54 includes a pressure plate 541 fixedly connected to the lower end of the fixed column 53, a pressure column 542 fixedly connected to the lower surface of the pressure plate 541, and a through hole provided on the surface of the pressure plate 541.

[0026] In this embodiment: when the pressure member 54 is pressed down, the pressure plate 541 and the pressure column 542 can press down on the surface of the hinge component respectively, thereby improving the stability during pressing down.

[0027] Specifically, a gasket 59 is fixedly connected to the lower surface of the pressure plate 541, and a circular pad 510 is fixedly connected to the lower end of the pressure column 542. During the pressing process, the pressure plate 541, together with the gasket 59, and the pressure column 542, together with the circular pad 510, can reduce the wear on the hinge components and improve the protection effect.

[0028] Specifically, a collection device 6 is provided on the surface of the machine body 1. The collection device 6 includes a collection box 61, which is located on one side of the machine body 1. An insert block 63 is fixedly connected to the surface of the collection box 61. A fixing block 62 is fixedly connected to the surface of the machine body 1. The fixing block 62 is inserted into the inner wall of the insert block 63. A guide plate 64 is fixedly connected to the surface of the machine body 1. A discharge port is opened on the surface of the rotating disk 2 located below the punching die 4.

[0029] In this implementation scheme: the waste material from punching can be discharged into the guide plate 64 through the discharge port on the surface of the rotating disk 2. The guide plate 64 can guide the waste material into the collection box for easy collection.

[0030] Specifically, connecting rods 66 are fixedly connected to both sides of the guide plate 64, and baffles 65 are fixedly connected to the surface of the connecting rods 66. During the material guiding process, the baffles 65 can intercept the waste material to ensure that the waste material can stably enter the collection box.

[0031] Working principle: During use, the hinge component with punched holes can be placed in the punching die 4. The rotating disk 2 feeds the component to the punching area. After being conveyed to the punching area, the pressing cylinder 51 first starts working. The pressing cylinder 51 can drive the frame 52, the fixed column 53, and the pressing component 54 to move. The guide rod 57 can guide the frame 52. When it moves to a certain position, the positioning ring 58 on the surface of the guide rod 57 can contact the bracket 3 for positioning. At this time, the pressure plate 541 and the pressure column 542 in the pressing component 54, together with the shim 59 and the round pad 510, can accurately fit and press down on the hinge component. Then, the punching cylinder 55 is opened, which can drive the punching head 56 to move, and cooperate with the punching die 4 to realize the punching process. The punched material can be discharged from the discharge port under the rotating disk 2 into the guide plate 64. The guide plate 64, together with the baffle 65, discharges the waste into the collection box for collection. When the punching is finished, the punching cylinder 55 drives the punching head 56 to reset. Since the pressure plate 541 and the pressure column 542 are still pressing down on the hinge component, the phenomenon of being pulled up is reduced. After the punching head 56 is reset, the pressing cylinder 51 can drive the frame, the fixed column 53 and the pressure component 54 to reset, and the use is completed.
