Fig. 9 FIG. 1 is a schematic diagram of the structure of the support block of the punching device in the first embodiment of the present invention. Figures 1 to 9As shown, the punching equipment of this embodiment is suitable for the ladder frame of a wind power tower, comprising: a punching mechanism 1, a punching plate 2, a guide assembly 3 and an inner support plate 4. The punching plate 2 is provided with a punching column 5, the punching plate 2 is arranged on the punching mechanism 1, the punching mechanism 1 is used to drive the punching plate 2 to move up and down, the guide assembly 3 is arranged below the punching plate 2, a punching hole is provided on the guide assembly 3, the punching column 5 is clamped in the punching hole, a guide slide is provided on the guide assembly 3, the inner support plate 4 is movably arranged in the guide slide, the inner support plate 4 is provided with a guide hole matched with the punching column 5, and the ladder frame passes through the inner support plate 4.

[0055] Specifically, in this embodiment, the stamping mechanism 1 is divided into two groups, and the two groups of stamping mechanisms 1 are symmetrically arranged front and back. The stamping mechanism 1 includes: a stamping cylinder 6 and a connecting piece 7, the connecting piece 7 is in an inverted T shape, the top of the connecting piece 7 is fixed to the bottom end of the stamping cylinder 6 by bolts, the bottom surface of the connecting piece 7 is fixedly connected to the punching plate 2, the stamping cylinder 6 is connected to the air pump, and there are two stamping columns 5, and the two stamping columns 5 are symmetrically fixed to the bottom surface of the punching plate 2 front and back. There are two groups of guide assemblies 3, which are respectively arranged directly below the punching plates 2 of the two stamping mechanisms 1, and the guide assemblies 3 are provided with stamping holes corresponding to the two guide columns 13 and having the same cross-section as the guide columns 13, and the guide assemblies 3 are provided with two guide slides, which are arranged inside the guide assemblies 3, and the guide slides are arranged in the left and right directions, and the guide slides pass through the guide assemblies 3 from left to right, and the two guide slides are respectively arranged directly below the two stamping columns 5. There are two inner support plates 4, which are movably arranged in two guide slides. The inner support plate 4 is fixed to the left end of the punching equipment through a guide bar 43. The right end of the inner support plate 4 is chamfered, and the inner support plate 4 is provided with guide holes adapted to the two stamping columns 5. The size of the guide hole is slightly larger than the size of the stamping hole. When in use, four ladder frames can be simultaneously passed through the guide slide for processing.

[0056] It is not difficult to find from the above content that when the punching device is used, the ladder frame is inserted into the guide slide from the right side of the guide assembly 3, and the punching cylinder 6 is turned on. The punching cylinder 6 drives the punching plate 2 to move downward and then punch holes on the ladder frame. Since the inner support plate 4 is set at the left end of the punching device through the guide bar 43, the inner support plate 4 will naturally sink to the guide slide under the influence of gravity. The right end of the inner support plate 4 is chamfered, so that when the staff pushes the ladder frame into the guide slide, the ladder frame acts on the chamfered surface of the inner support plate 4, and then the inner support plate 4 is propped up and inserted into the inside of the ladder frame, without the need to manually align the inner support plate 4 and the ladder frame. In this way, when the punching cylinder 6 drives the punching column 5 to punch the ladder frame downward, the inner support plate 4 can support the upper and lower sides of the ladder frame, reducing the amount of deformation of the ladder frame due to extrusion. A punching hole is provided on the guide assembly 3 so that the punching column 5 is clamped in the punching hole, which can guide the punching column 5 during the descent process and can make the punching position of the punching column 5 on the ladder frame more accurate; a guide slot is provided on the guide assembly 3, and the guide slot is provided in the middle of the guide assembly 3, which can assist the sliding of the ladder frame in the left and right directions on the one hand, and can restrict the stamping column 5 from the guide assembly 3 during the retraction process on the other hand, and then automatically detach from the ladder frame to facilitate subsequent processing.

[0057] Optionally, the guide assembly 3 includes: a base plate 8, a lower plate 9, two middle plates 10 and an upper plate 11, the base plate 8 is provided with a first feed hole, the first feed hole is located below the stamping column 5, the base plate 8 is provided with a plurality of guide columns 13, the punching plate 2 is provided with a guide tube 14 compatible with the plurality of guide columns 13, the lower plate 9 is arranged on the base plate 8, the lower plate 9 is provided with a second feed hole, the second feed hole is located below the stamping column 5, two middle plates 10 are symmetrically arranged on the lower plate 9 front and back, the inner support plate 4 is located between the two middle plates 10, the middle plate 10 is provided with a plurality of rotating wheels 12, the upper plate 11 is arranged on the middle plate 10, and the stamping holes are arranged on the upper plate 11.

[0058] Specifically, in this embodiment, the bottom plate 8 is arranged horizontally, the lower plate 9 is arranged on the bottom plate 8, two middle plates 10 are arranged front-to-back symmetrically on the lower plate 9, the upper plate 11 is arranged on the two middle plates 10, the punching holes are arranged on the upper plate 11, and two first feed holes and two second feed holes are respectively arranged on the bottom plate 8 and the lower plate 9, and the two first feed holes and the two second feed holes are respectively located below the two punching holes. Four guide posts 13 are arranged on the upper surface of the bottom plate 8, and guide tubes 14 corresponding to the four guide posts 13 are arranged on the punching plate 2, and the guide posts 13 and the guide tubes 14 are arranged to assist the up and down movement of the punching plate 2. In addition, since two stamping columns 5 are provided on one punching plate 2, the guide assembly 3 also includes: an intermediate plate 15, the intermediate plate 15 is horizontally arranged on the upper plate 11, the intermediate plate 15 is arranged between the two middle plates 10, a plurality of rotating wheels 12 are provided on the side wall of the two middle plates 10 close to the intermediate plate 15, and a plurality of rotating wheels 12 are provided on the front and rear sides of the intermediate plate 15, and the guide slideway is the channel between the intermediate plate 15 and the middle plate 10. When in use, the two first feed holes can be set to one, because when the stamping column 5 stamps the ladder frame, when the first layer is stamped, the inner support plate 4 supports the upper side of the ladder frame side wall, and when the second layer is stamped, the lower plate 9 supports the lower side of the ladder frame, and the first feed hole only needs to be able to pass the waste generated by stamping. The rotating wheel 12 is provided to reduce the friction between the ladder frame and the middle plate 10, and reduce the wear of the ladder frame.

[0059] Optionally, it also includes: a traction mechanism 16, a controller (not shown in the figure), a sensor head 17, multiple sensors 18 and a workbench 19. The workbench 19 is provided with a third feed hole, and the third feed hole is located below the punching hole. The sensor is arranged on the punching plate 2, and multiple sensors 18 are vertically arranged on the workbench 19. The multiple sensors 18 are electrically connected to the controller respectively, and the multiple sensors 18 are used to transmit signals to the controller. The traction mechanism 16 is arranged on the workbench 19, and the traction mechanism 16 is used to drive the ladder frame to move left and right. The traction mechanism 16 and the punching mechanism 1 are electrically connected to the controller respectively, and the controller is used to control the opening and closing of the traction mechanism 16 and the punching mechanism 1.

[0060] Specifically, in this embodiment, the workbench 19 is arranged on the bracket 20, and at least two third material discharge holes are arranged. The two third material discharge holes are arranged respectively below the punching columns 5 of the two groups of punching mechanisms 1, so that the waste material punched out by the punching mechanism 1 can fall below the workbench 19 through the first material discharge hole, the second material discharge hole and the third material discharge hole.

The three sensors are electrically connected to the controller respectively, and the traction mechanism 16 is arranged on the left side of the two groups of punching mechanisms 1. The traction mechanism 16 and the punching cylinder 6 are both electrically connected to the controller. When in use, the ladder frame is passed through the guide slide and fixed on the traction mechanism 16, the traction mechanism 16 is turned on to drive the ladder frame, and the traction mechanism 16 drives the ladder frame to move to a certain position, so that the first punching position of the ladder frame is located below the stamping column 5, and then the controller controls the stamping cylinder 6 to drive the punching plate 2 to move downward. After descending to a certain position, the sensor 18 on the lower side senses the presence of the sensing head 17, and the lower side sensor sends a control signal to the controller. The controller controls the stamping cylinder 6 to drive the punching plate 2 to retract. When the middle sensor 18 senses the sensing head 17, the middle sensor sends a signal to the controller, and the controller controls the stamping cylinder 6 to stop. Then the controller controls the traction mechanism 16 to drive the ladder frame to move to the right to the second processing position located below the stamping column 5 and then stops. The controller then controls the stamping cylinder 6 to drive the punching plate 2 to move downward, punch the ladder frame again, and then repeat until completion. The staff will remove the processed ladder frame. This arrangement, on the one hand, facilitates the control of the spacing between each processing and improves the accuracy, and on the other hand, the traction mechanism 16 replaces manual pushing, saving labor, and the processed product has high integrity. In addition, when the upper sensor 18 senses the induction head 17, the upper sensor 18 sends a signal to the controller, and the controller controls the stamping cylinder 6 and the traction mechanism 16 to stop working, thereby improving the safety of the equipment.

[0061] Furthermore, the traction mechanism 16 includes: a driving mechanism 23, a sliding assembly 24 and a clamping mechanism 25.
