[0001] The utility model belongs to the technical field of steel processing, and in particular relates to a punching device for steel processing which is easy to position. Background Art

[0002] Steel is widely used and has many varieties. According to the different cross-sectional shapes, steel is generally divided into four categories: profiles, plates, pipes and metal products. It is further divided into heavy rails, light rails, large-sized steel, medium-sized steel, small-sized steel, cold-formed steel, high-quality steel, wire, medium-thick steel plates, thin steel plates, electrical silicon steel sheets, strip steel, seamless steel pipes, welded steel pipes, metal products and other varieties;

[0003] When processing steel, holes are punched into the steel according to the required use of the steel. When punching holes in a steel plate, when holes need to be punched at different positions of the steel plate, the steel plate needs to be moved. However, when the mass of the steel plate is large, it is inconvenient to move the steel plate, and it is also easy to cause inaccurate positioning of the holes. Utility Model Content

[0004] In view of the problems raised by the above background technology, the purpose of the utility model is to provide a punching device for steel processing that is easy to position.

[0005] In order to achieve the above technical purpose, the technical solution adopted by the utility model is as follows:

[0014] Compared with the prior art, the utility model has the following advantages:

[0015] The utility model has a simple structure. A universal wheel is arranged on a processing table. When a steel plate is placed on the universal wheel, the universal wheel supports the steel plate.

DETAILED DESCRIPTION

[0024] In order to enable those skilled in the art to better understand the present invention, the technical solution of the present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0025] like Figure 1-4 As shown, a punching device for steel processing that is easy to position includes a processing table 1, a punching assembly 2 is fixedly assembled and connected on the upper side of the processing table 1, positioning members 21 are symmetrically fixedly connected on both sides of the punching assembly 2, four universal wheels 3 are symmetrically assembled and connected on the upper side of the processing table 1, the processing table 1 is provided with a lifting assembly 4, and legs 11 are provided at the four corners of the lower side of the processing table 1;

[0026] The lifting assembly 4 includes a base plate 401, a telescopic cylinder 402, a connecting plate 403, a connecting rod 404 and a support plate 405. The telescopic cylinder 402 is assembled and connected to the upper side of the base plate 401, the connecting plate 403 is assembled and connected to the upper side of the telescopic cylinder 402, the connecting rod 404 is assembled and connected to the upper side of the connecting plate 403, and the support plate 405 is assembled and connected to the upper side of the connecting plate 403. The base plate 401 and the support leg 11 are located in the same horizontal plane, and the highest point of the support plate 405 is lower than the universal wheel 3.

[0027] By adopting the technical solution of this embodiment, the punching assembly 2 is used to punch holes in the steel plate. The position of the punching assembly 2 is fixed, and the universal wheel 3 is convenient for moving the steel plate. When punching holes in other positions of the steel plate, the universal wheel 3 can reduce the force used to move the steel plate. It should be noted that when the telescopic cylinder 402 is in the initial position, the upper plane of the support plate 405 is lower than the highest point of the universal wheel 3, so the steel plate is first moved onto the universal wheel 3. The area of ​​the steel plate is large enough to contact the four universal wheels 3, and then the position where the steel plate is to be punched is aligned with the punching assembly 2, and then the telescopic cylinder 402 is started to move the support plate 405 upward, the steel plate contacts the positioning piece 21, the steel plate is fixed, and then the punching assembly 2 is started to punch holes in the steel plate. After the punching is completed, the telescopic cylinder 402 is then moved downward, the steel plate contacts the universal wheel 3, and the steel plate is moved. The universal wheel 3 saves the force used to move the steel plate.
