630 tons of longmen shears, equipped with two main shear cylinders with an inner diameter of 420, can reach 700 tons of shear pressure, piston rod, piston guide sleeve using medium frequency quenching process, hardness 50-55 degrees, greater to avoid oil leakage caused by impact damage, piston rod plating side 0.05mm, To ensure that the oil cylinder is more and more smooth and more and more bright, the piston rod head and the tool holder are connected with the ball head, which can adjust the error by itself, and the oil cylinder will not break.

Overall cast steel tool holder, better integrity, more solid, fixed blade nut can be hidden in the interior, will not be caused by the impact of the screw deformation is not easy to disassemble.

There are two specifications of 1.6m / 1.8m knife edge for customers to choose, the blade is made of Maanshan h13 material, and the h13 material cushion layer added below the blade can effectively protect the main body of the machine, and the knife change is more convenient. The four sides of the blade can cut about 10,000 tons of wool, which is suitable for small and medium-sized materials with a monthly output of about 3,000 tons.

The slide lining plate on both sides of the cutter seat uses high-force brass and adds graphite, with a hardness of 30 degrees, and the guide groove uses 65 manganese plate, with a hardness of 50 degrees, and is equipped with an oil groove, a soft and hard to reduce friction while realizing automatic lubrication, which greatly reduces the problem of slide wear; The slide adjustment function is also designed on both sides of the slide, which can adjust the gap between the upper and lower blades to solve the problem that thin materials are not easy to cut after cutting thick materials for a long time.

The 630-ton gantry shears are equipped with a 7-meter material box, the cylinder is pushed one-sided heavier door cover, and the lining plate of the material box is made of nm500 wear-resistant plate, which has high wear-resisting strength and long service life. The riveting welding process is adopted, making it difficult to weld the drum warping edge. At the same time, four slides are designed on the three sides of the material box, which can effectively prevent the problem of pushing the head warping the head.

Hydraulic station part is also the core part of the whole machine, power is equipped with a 92.1kw servo motor, drive a4v280 series a4v280 high-speed oil pump, large flow, lower noise, automatic start and stop, energy saving.

The inside of the tank can be sandblasted to remove rust, and 25 barrels of 46 anti-wear hydraulic oil can be added.

The pipeline is also pickling phosphating treatment to ensure that the equipment is not stuck in the later use of valve blocking valve, plate cooling with large flow centrifugal oil pump, cooling effect is better.

The control part is controlled by plc automatic + remote control, which can be operated by one person and one excavator, saving labor and improving work efficiency.

Gantry shear is a kind of industrial equipment widely used for cutting scrap metal, especially for large scrap recycling station, with simple structure and high efficiency. It can cut various shapes of metal, such as scrap steel, round steel, square steel, steel plate, heavy scrap steel, etc., suitable for metal recycling processing plants, scrap car dismantling field, smelting and casting industry.
