Technical Field

[0001] The utility model relates to the technical field of parts production and processing, in particular to a shearing device which can automatically adjust shearing size. Background Art

[0002] A shear is a type of machine tool that utilizes a hydraulic drive, offering reliable safety and ease of operation. Shear blade lengths are available in 400mm, 600mm, 700mm, 800mm, 1000mm, and 1200mm, with a shearing force range of eight levels, from 63 tons to 400 tons, to suit different sizes and requirements. Foot screws are installed, and diesel engines can be used for power in locations without a power source. Shears are suitable for metal recycling plants, scrap car dismantling yards, and smelting and foundry industries, performing cold shearing and flanging of various shapes of steel and other metal materials, as well as forming powdered products, plastics, fiberglass, insulation materials, and rubber. Shears are categorized into various types: metal shears, combined punching and shearing machines, hydraulic shears, and bar shears. The most commonly used metal shears are crocodile shears and gantry shears. Shears are mechanical devices used to cut metal materials. During the rolling process, large-section steel ingots and billets are reduced in cross-section and increased in length after rolling. In order to meet the requirements of subsequent processes and product size specifications, shearing processes are necessary in the production process of various steel products.
