Description

Technical Field

[0001] The utility model relates to the technical field of scrap iron recovery, in particular to a scrap iron recovery shearing device. Background Art

[0002] Scrap steel refers to the steel waste (such as trimmings, heads, etc.) that does not become products during the production process of steel mills, as well as the steel materials in equipment and components that are scrapped after use. Scrap steel is steel, and scrap iron is pig iron. They are collectively called scrap steel. At present, the total amount of scrap steel produced in the world each year is 300 to 400 million tons, accounting for about 45 to 50% of the total steel production, of which 85 to 90% is used as steelmaking raw materials, and 10 to 15% is used for casting, ironmaking and recycled steel. When recycling steel materials, scrap steel shearing equipment is needed to process them for easy recycling and transportation.

[0003] The existing Chinese patent with authorization announcement number CN219275063U discloses a gantry shearing device for recycling scrap steel, including a support leg, a steel collection box is fixedly provided on the top of the support leg, a shearing platform is fixedly provided on the top of the steel collection box, a protective cover is fixedly provided on the top of the shearing platform, a stamping mechanism and a shearing mechanism are fixedly provided on the protective cover, a clamping mechanism is fixedly provided on the shearing mechanism, a feed opening is opened on one side of the shearing platform at the top of the steel collection box, a pushing mechanism is provided on one side of the steel collection box, and a cleaning door is provided on the front side of the steel collection box.

[0004] The current scrap iron shearing equipment has gradually been found to have the following defects during use:

[0005] (1) The above-mentioned scrap iron shearing equipment only presses the scrap iron on one side of the shearing tool when shearing the scrap iron, while no pressing measures are set on the other side. The scrap iron is prone to warping and splashing during shearing. At the same time, the tools used in the shearing equipment are connected by screws. After a long time, the screws rust and are difficult to disassemble. When replacing the worn tools, not only a lot of time will be wasted, but also work efficiency will be reduced.

[0006] (2) In the above-mentioned shearing equipment, there is no shearing notch directly below the shearing tool, which can easily damage the tool during shearing, resulting in the need to frequently replace the tool, increasing costs. At the same time, some debris will be generated during shearing, and a large amount of debris will accumulate on the shearing platform, affecting the shearing work of the shearing equipment. Stopping the machine for cleaning will waste a lot of working time.

[0007] (3) The above-mentioned shearing equipment performs an extrusion operation on the sheared scrap iron, but after extrusion, the extruded scrap iron needs to be manually carried out of the equipment. Since the sheared scrap iron has too many sharp ends, it is easy to cause manual scratches on the hands, and rust can also cause other infections, which not only increases the labor intensity of the manual workers, but also causes harm to the manual workers.
