[0024] The utility model is further described below in conjunction with the accompanying drawings and embodiments:

[0025] A punching device for processing angle steel tower accessories, see Figures 1 to 4 , comprising a base 1, a bracket 2 is connected to the surface of the base 1, a slide rail 3 is provided on the surface of the bracket 2, a slide 4 is provided on the surface of the slide rail 3, a punching mechanism 5 is provided at the front end of the slide 4, and a limiting mechanism 6 is provided below the punching mechanism 5;

[0026] The punching mechanism 5 includes a limit frame 501, which is fixed to the inner side of the front end of the slide 4. A hydraulic cylinder 502 is inserted into the limit frame 501. The movable end of the hydraulic cylinder 502 is connected to a support plate 503. A group of guide rods 504 are provided on the middle surface of the support plate 503, wherein a guide groove matching the guide rods 504 is opened inside the vertical part of the limit frame 501. A motor 505 is provided at the rear of the support plate 503 surface. A driving wheel 506 is connected to the movable end of the motor 505. A punching assembly 507 is provided in front of the driving wheel 506. A transmission belt 508 is provided on the outside of the driving wheel 506 and the punching assembly 507. Furthermore, the motor 505 forms a transmission rotating structure through the driving wheel 506, the transmission belt 508 and the punching assembly 507. The utility model uses a hydraulic cylinder 502 to effectively drive the support plate 503 to move vertically, thereby driving the punching assembly 507 to move vertically, thereby realizing the punching of the diagonal steel tower steel plate. The matching engagement between the guide rod 504 and the guide groove opened inside the vertical part of the limit frame 501 can maintain the vertical movement stability of the support plate 503. The motor 505 effectively drives the driving wheel 506 to rotate. At the same time, the punching assembly 507 is rotated under the action of the transmission belt 508, which makes it easier for the grinding part of the punching assembly 507 to grind the inside of the punched hole and reduce burr residue.

[0027] It is worth noting that the punching assembly 507 includes a driven wheel 507a, a clamping block 507b is fixedly connected to the top of the driven wheel 507a, a screw 507c is threadedly connected to the inside of the driven wheel 507a, a clamping rod 507d is fixedly connected to the bottom of the screw 507c, a punching needle 507e is fixedly connected to the bottom of the clamping rod 507d, a grinding rod 507f is sleeved on the outside of the clamping rod 507d, and further, the grinding rod 507f is matched and sleeved on the outside of the clamping rod 507d, and the punching needle 507e forms a detachable structure with the clamping rod 507d, the screw 507c and the driven wheel 507a. In the utility model, the punching needle 507e is used to contact the steel plate to realize punching, and the grinding rod 507f is used to contact the inside of the punching hole to realize the cleaning of the residual burrs in the punching hole. The grinding rod 507f is effectively limited to the upper end of the punching needle 507e through the cooperation and engagement between the clamping rod 507d and the grinding rod 507f, so that the movement paths of the punching needle 507e and the grinding rod 507f are unified. Since the clamping rod 507d and the grinding rod 507f are plug-in connected, when the punching needle 507e is disassembled and replaced after the screw 507c is screwed, the grinding rod 507f can also be directly pulled out and disassembled, which is more convenient.

[0028] It is worth noting that the limiting mechanism 6 includes a vertical plate 601, which is fixed to the surface of the base 1, a hydraulic cylinder 2 602 is provided on one side of the vertical plate 601, a bracket 603 is connected to the movable end of the hydraulic cylinder 2 602, a slider 604 is provided at the bottom of the bracket 603, a slide rail 2 605 is clamped inside the slider 604, and a steel plate placement rack 606 is connected inside the bracket 603, wherein the bracket 603 and the steel plate placement rack 606 are fixedly connected, and the bracket 603 forms a sliding structure through the hydraulic cylinder 2 602, the slider 604 and the slide rail 2 605. In the utility model, the hydraulic cylinder 2 602 can drive the bracket 603 to slide on the slide rail 2 605, so as to facilitate the front and rear position adjustment of the steel plate placed inside the steel plate placement rack 606, and at the same time, the slide 4 can move left and right on the slide rail 1 3, so as to facilitate the punching of different positions of the steel plate placed inside the steel plate placement rack 606, thereby improving the applicability of the device.

[0029] Working principle: first place the angle steel tower steel plate inside the steel plate placement rack 606, then adjust the position of the slide 4 so that the punching mechanism 5 is above the required punching position of the steel plate, and drive the support plate 503 to move vertically through the hydraulic cylinder 502, thereby driving the punching assembly 507 to move vertically, so as to realize the punching of the angle steel tower steel plate by the punching needle 507e. After the punching is completed, the movable part of the hydraulic cylinder 502 continues to extend downward, and at the same time, the active wheel 506 is driven to rotate by the motor 505. At the same time, the punching assembly 507 is rotated by the transmission belt 508, so that the grinding rod 507f can grind the inside of the punching hole to reduce burr residue. Since punching and burr grinding can be completed together in a short time, the processing efficiency is improved. After that, the position of the punching mechanism 5 and the angle steel tower steel plate can be further adjusted on the basis of separation of the punching mechanism 5 and the angle steel tower steel plate to realize continuous punching.
