Description

A slot punching device for angle steel production Technical Field

[0001] This utility model relates to the technical field of punching devices, specifically a slot punching device for angle steel production. Background Technology

[0002] Angle steel is a common type of steel that is widely used in the construction, machinery manufacturing, and transportation industries.

[0003] In the production of angle steel, punching devices are typically used to punch holes in the angle steel according to the subsequent usage requirements, in order to connect and fix the components. Existing punching devices usually consist of a punching machine and a punching table. In use, the angle steel is first fixed on the punching table, and then the drive mechanism on the punching table is used to control the movement of the angle steel or the punching machine to adjust the punching position. Finally, the punching machine punches the angle steel to complete the punching operation.

[0004] However, in most cases, angle steel may need to be connected to multiple components, each with different connection methods and connectors. Therefore, the shape and size of the holes punched on the angle steel should also vary. Existing punching machines typically have fixed punch head shapes. When punching holes of different shapes or sizes is required, the punch head needs to be frequently changed. This is not only inconvenient to operate but also time-consuming, affecting the processing efficiency of angle steel. To address these shortcomings, we propose a slot punching device for angle steel production. Summary of the Invention

[0005] The purpose of this utility model is to provide a slot punching device for angle steel production, which solves the problems mentioned in the background art.

[0012] Compared with the prior art, this utility model provides a slot punching device for angle steel production, which has the following beneficial effects:

[0013] This invention features a movable switching platform located below the punching cylinder. Multiple punching heads of different types are mounted on the switching platform. The punching cylinder presses against a slider, causing the slider to move the punching heads downwards to punch angle steel. When punching different hole diameters and shapes is required, simply controlling the switching platform allows different punching heads to be aligned directly below the punching cylinder, eliminating the need for disassembly or other operations. This makes it convenient and quick to use. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please refer to Figures 1-5. A slot punching device for angle steel production includes a punching table 1, a gantry frame 2 fixedly mounted on the punching table 1, a punching cylinder 3 fixedly mounted vertically on the inner top surface of the gantry frame 2, and a switching table 4 movably mounted on the inner side of the gantry frame 2. The switching table 4 is located directly below the punching cylinder 3 and has several sliders 5 mounted on it. The sliders 5 are all slidably connected to the switching table 4 vertically. During the punching operation, one of the sliders 5 needs to be located directly below the movable end of the punching cylinder 3. A pressure plate 301 is fixedly mounted on the movable end of the punching cylinder 3 to increase the contact area with the slider 5, so that the slider 5 is subjected to uniform force, thereby better completing the punching operation. A punch head 501 is fixedly provided on the bottom surface of several sliders 5, and the shape of the punch head 501 on the bottom surface of different sliders 5 is different. Therefore, when different sliders 5 are located directly below the punching cylinder 3, the punching cylinder 3 can drive different punch heads 501 to punch the angle steel, thereby realizing the function of quickly switching between different specifications of punching patterns.

[0022] The upper surface of the punching platform 1 is also provided with a punching seat 101, which is used to support and fix the angle steel. As shown in Figures 1 and 2, the punching seat 101 is L-shaped and consists of two parts, the lower part is fixedly installed on the upper surface of the punching platform 1, and the upper part is connected to the lower part through a telescopic rod. Therefore, the upper part can move up and down to adapt to the fixing of angle steel with different side lengths.

[0023] Furthermore, the switching platform 4 is rectangular in shape and is distributed along the length of the punching platform 1. The switching platform 4 is slidably connected to the gantry frame 2 along the length of the punching platform 1. Specifically, as shown in Figures 2 and 3, linear slides are fixedly installed on the left and right inner sidewalls of the gantry frame 2, and the left and right sidewalls of the switching platform 4 are connected to the slide blocks of the linear slides, so that the switching platform 4 can be automatically controlled to move. A rectangular opening 401 is vertically through the switching platform 4, and several sliders 5 are located within the rectangular opening 401, distributed along the length of the switching platform 4. Therefore, when the switching platform 4 moves along the length of the punching platform 1, it can drive the several sliders 5 to move synchronously, realizing the switching of the punching head 501.

[0024] Unlike the above embodiments, the switching table 4 can also be set as a cylinder, and several sliders 5 can be arranged circumferentially on the switching table 4. The switching table 4 can be rotated by a motor or other drive mechanism, which can also achieve the purpose of switching the punch head 501.

[0025] In this embodiment, slide plates 502 are fixedly provided on both the left and right sidewalls of the slider 5. Several through holes 402 are provided on the inner sidewall of the rectangular opening 401. The through holes 402 penetrate the sidewall of the switching platform 4 along the width direction of the switching platform 4. Several through holes 402 and several slide plates 502 correspond one-to-one, and the slide plates 502 are slidably connected in the through holes 402 in the vertical direction. The width of the slider 5 is equal to the width of the rectangular opening 401, and the width of the slide plate 502 is equal to the width of the through hole 402. Therefore, the slider 5 cannot move in the front-back or left-right direction in the rectangular opening 401, making the lifting and lowering movement of the slider 5 more stable.

[0026] Furthermore, a spring 6 is provided vertically inside the through hole 402. The upper and lower ends of the spring 6 are respectively connected to the bottom surface of the slide plate 502 and the bottom surface of the through hole 402. In its natural state, the spring 6 is in a compressed state so that the punch head 501 can rise and reset after the punching operation is completed, which facilitates the next punching operation.

[0027] In order to ensure that the slider 5 performing the punching operation is directly below the punching cylinder 3, the end of the slide plate 502 away from the slider 5 extends to the outside of the through hole 402. The upper surface of the part of the slide plate 502 extending out of the through hole 402 is provided with a positioning hole 503. A positioning cylinder 7 is fixedly installed on the inner top surface of the gantry 2. The positioning cylinder 7 is arranged vertically, so the movable end of the positioning cylinder 7 can move up and down. Furthermore, the diameter of the movable end of the positioning cylinder 7 is not greater than the diameter of the positioning hole 503, so the movable end of the positioning cylinder 7 can pass through the positioning hole 503.

[0028] The working principle and usage process of this utility model are as follows: When in use, first place the angle steel on the punching seat 101. Then, select the corresponding punching head 501 according to the punching requirements. Use the linear slide to control the switching table 4 to move until the corresponding punching head 501 is directly below the punching cylinder 3. Then, control the movable end of the positioning cylinder 7 to insert into the positioning hole 503 to complete the positioning operation. Finally, the punching cylinder 3 can drive the slider 5 and the punching head 501 to descend, and use the punching head 501 to perform the punching operation on the angle steel.
