Description

Technical Field

[0001] The invention relates to the technical field of steel cutting, and in particular to a steel cutting device. Background Art

[0002] Steel is a material of a certain shape, size and performance made from steel ingots, billets or steel through pressure processing. Most steel processing is done through pressure processing, which causes plastic deformation of the processed steel (billets, ingots, etc.). Depending on the processing temperature of steel, it can be divided into cold processing and hot processing.

[0003] Finished steel products include steel pipes, steel plates, steel sections, and steel wires. Among them, steel sections are the most widely used steel in actual production. According to the cross-sectional shape, steel sections are divided into simple cross-sectional steel sections and complex cross-sectional steel sections (special-shaped steel sections). The former refers to square steel, round steel, flat steel, angle steel, hexagonal steel, etc.; the latter refers to I-beams, channel steel, rails, window frame steel, curved steel sections, etc.

[0004] The steel sections obtained by hot rolling, cold drawing or forging need to be cut before use to obtain steel of different sizes and used in different production links such as assembly and welding.

[0005] Obviously, the cutting quality of steel will directly affect the ease of installation and subsequent stability of use. However, the existing steel cutting devices have the following problems in the process of cutting C-shaped steel or U-shaped steel: 1. The first is the problem of cutting deformation. Traditional technology usually uses flame cutting or plasma cutting to cut steel. A lot of heat will be generated during the cutting process. This heat cannot be dissipated in time, which will cause the steel in the cutting area to soften and deform due to heat. In severe cases, it is necessary to perform secondary deformation correction, which adds unnecessary processing steps and reduces processing efficiency.

[0006] 2. The second problem is the difficulty in adjusting the processing volume. As mentioned above, in the application process, steel sections are usually assembled and welded together to form a specific steel frame structure, which requires a large number of steel sections of different lengths. Obviously, these steel sections need to be cut and processed by the same equipment, which requires frequent and real-time adjustments to the processing benchmarks of existing equipment during the cutting process. These adjustments include but are not limited to changes in the clamping position, changes in the cutting angle, etc., making the entire steel cutting process extremely cumbersome and complicated to operate and inconvenient to use.

[0007] 3. Finally, there is the problem of inconvenient clamping. There are two main clamping problems in the steel cutting process. First, the shape of the steel itself is irregular and the cross-section is small, making it difficult to achieve complete clamping and fixing. Second, the existing cutting equipment clamps the uncut part of the steel, but does not clamp and fix the cut part, causing the part to bend and deform under the influence of gravity during the cutting process, affecting the cutting quality. In addition, the cut part falls directly on the ground and is prone to bumping, affecting the subsequent assembly process.

[0008] In summary, the prior art obviously has inconveniences and defects in practical use, so it is necessary to improve it. Summary of the invention

One end of the high-pressure water pipe is fixedly connected to the connecting water channel in the fixed mounting seat, and the other end extends to the outside of the first workbench.
