400 tons of longmen shears, equipped with two main shear cylinders with an inner diameter of 320, piston rod, piston guide sleeve adopts medium frequency quenching process, hardness 50-55 degrees, greater to avoid the phenomenon of oil leakage caused by impact damage, the piston rod plating side of 0.05mm, to ensure that the cylinder is more and more smooth, more and more bright, the head of the piston rod and the knife holder are connected with a ball head. The error can be adjusted by itself, and the cylinder will not break.

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.

400 tons gantry scissors configuration.

6 meters material box, the cylinder push one-sided heavy door cover, the material box internal liner using nm500 wear-resistant plate, high wear-resistant strength, long service life, the use of riveting welding process, not easy to open welding drum warping edge, while the three sides of the material box designed four slides, can effectively prevent the push head warping head stuck material and other problems.

The hydraulic station is also the core part of the whole machine, and the power is equipped with a 62kw servo motor, which drives two a4v200 high-speed oil pumps, with large flow, lower noise, automatic start and stop, energy saving.

The inside of the tank can be sandblasted to remove rust, and 15 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.
