Description

Technical Field

[0001] This utility model relates to the field of shearing technology, specifically to a scrap steel gantry shear. Background Technology

[0002] Gantry shears are suitable for metal recycling plants, scrap car dismantling yards, and smelting and casting industries to cold-cut various metals and process them into qualified furnace materials. However, existing gantry shears generally have low shearing efficiency, and for some hard and brittle steels, the steel being sheared may sometimes bounce off during shearing, making the discharge direction of the shearing device dangerous and prone to causing injury.

[0003] A search revealed that publication number CN211758858U discloses a material shearing device for a gantry shear. The gantry shear material shearing device includes: a shear head casting; a rotating plate disposed on one side of the shear head casting; a baffle fixedly installed on the rotating plate on the side away from the shear head casting; and a mounting block disposed on one side of the shear head casting, positioned above the rotating plate. This utility model's gantry shear material shearing device, by setting a baffle, can effectively block some harder and brittle steel materials that are ejected, preventing injury from ejected steel and making the working environment safer. Simultaneously, with the cooperation of the threaded sleeve and the lead screw, the baffle can deflect, making it easier to unload when shearing a large number of smaller steel bars or wire ropes at once. However, this device does not fix the material during shearing, which can easily lead to poor shearing. Furthermore, scrap steel surfaces are often covered with iron filings, generating a large amount of debris during shearing that is difficult to clean. Therefore, a scrap steel gantry shear is proposed. Utility Model Content

[0014] (III) Beneficial Effects

[0015] Compared with the prior art, this utility model provides a scrap steel gantry shear, which has the following beneficial effects:

[0016] (1) This utility model adopts a first hydraulic telescopic column, a second hydraulic telescopic column, a pressure plate, a shearing blade, a servo motor, a unidirectional motor, and a vacuum cleaner. In actual use, the material is placed into the frame through the through slot, and the first hydraulic telescopic column is started at the same time. The first hydraulic telescopic column drives the pressure plate to rise, and the pressure plate presses and fixes the material. At the same time, the second hydraulic telescopic column is started, and the shearing blade is driven by the second hydraulic telescopic column to shear the material. The vacuum cleaner is started at the same time as shearing. The vacuum cleaner transports the debris generated by shearing to the dust collection point through the suction pipe and suction port. The material is collected inside the box. After shearing, the servo motor, unidirectional motor, and vacuum cleaner are activated. The servo motor drives the unidirectional motor through the slide, slider, and screw. The unidirectional motor drives the cleaning roller connected to the output end to clean the surface of the workbench. The iron filings generated during cleaning are transported to the dust collection box through the vacuum cleaner, suction pipe, and suction port. The collection of iron filings facilitates later recycling. By pressing and fixing the material, it is prevented from moving during shearing and causing poor shearing. At the same time, it prevents hard and brittle steel from being ejected during shearing, thus protecting the workers. Attached Figure Description
