Operating principle of gantry shears

Operating principle of gantry shears

TEYUN Gantry shear is a type of equipment suitable for heavy scrap shearing. It is used to cold-shear various scrap metals such as scrap copper, scrap steel, scrap iron, metal briquettes, car bodies, aluminum alloys, copper materials, etc., and process them into qualified furnace materials. Gantry shear have a wide range of applications. They can be used as processing equipment for metal recycling units, furnace materials processing in factory casting workshops, and metal shearing processing equipment in the machinery and construction industry. Operating principle: TEYUN Gantry shears are composed of the frame, hydraulic cylinder, hydraulic power system, and an electrical system. In terms of working principle, after the material is grabbed into the feeding box, the waste material is pushed by the push cylinder or automatically sent to the cutting edge by the conveyor belt. The feeding speed can be adjusted by the speed regulating motor. Side extrusion cylinders are installed on both sides of the material box. Large waste materials such as scrapped cars cannot pass through the cutting edge of the gantry shears. The waste material can be squeezed and reduced by the side extrusion cylinders, and then sent to the cutting edge through the conveyor table for cutting.
Introduction of Alligator shear

Introduction of Alligator shear

Alligator shears are called crocodile shears, which are named for their crocodile-like shape. They are widely used in metal recycling companies, scrap steel factories, and smelting enterprises. The alligator shears can cold-cut scrap metal structures with different cross-sectional shapes and process them into qualified furnace materials. In general, alligator shears are more suitable for personal scrap metal recycling stations. The alligator shearing machine is equipped with an integrated electromagnetic valve device for rapid pressure regulation, which can cut about 8-9 times a minute, and the shearing speed is twice as high as the original one. Features of crocodile shears Adopt hydraulic drive, easy to operate and easy to repair. Working blade length: 400mm, 600mm, 700mm, 800mm, 1000mm, 1200mm, 8 levels of shear force from 63 tons to 400 tons. The shearing machine with a knife edge of more than 700mm is suitable for cutting scrapped cars. The installation does not need anchor screws, and the diesel engine can be used as power in places without power supply. The alligator shear adopts hydraulic transmission. Compared with the mechanical transmission shearing machine, it has the advantages of small size, light weight, low inertia, low noise, stable movement, convenient operation, sensitivity, large cutting section, and convenient adjustment of the scissors. It is safe to operate and use, and it is easy to realize overload protection. Precautions for using crocodile shears The crocodile shears must be filled with oil before each shift, and the places with butter nozzles must be buttered. It is strictly forbidden for non-designated personnel to operate the crocodile shears, and it is necessary to stop the machine without people. Regularly check the travel switch, solenoid valve connector, and hydraulic oil on the back of the crocodile shears.
