Structural Characteristics：
1. Gantry frame: welded with high-strength steel plates to form a stable gantry shape structure. This frame design makes the equipment have good rigidity and stability, can withstand the huge pressure generated in the shearing process, ensure that the equipment does not deform under high strength work, and ensure the shear accuracy and the service life of the equipment.
2. Cutting mechanism: consists of fixed blade and active blade. The blades are usually made of high-quality alloy tool steel and undergo special heat treatment processes to provide high hardness, high wear resistance and excellent impact resistance. The movable blade is driven by the hydraulic cylinder, which can be quickly and powerfully closed with the fixed blade to achieve efficient cutting of metal materials.Machine For Cutting Steel
3. Hydraulic system: It is the power source of hydraulic gantry scissors, mainly composed of oil tank, oil pump, hydraulic valve group, hydraulic cylinder and other components. The oil pump pressurizes the hydraulic oil in the tank, and precisely controls the flow direction and pressure of the oil through the valve group, so that the hydraulic cylinder generates a powerful thrust and drives the movable blade to complete the shear action. By adjusting the pressure of the hydraulic system, the shear requirements of metal materials of different materials and thicknesses can be adapted.Scrap Metal Shredder
4. Feeding and discharging device: The feeding device is generally equipped with a conveyor track or conveyor belt to facilitate the stable feeding of waste metal materials into the shear area. The discharge device is responsible for transporting the cut metal block to the designated location for subsequent collection and transportation. Some advanced hydraulic gantry shears also have automatic feeding and discharging functions, which greatly improves production efficiency.
5. Control system: used to control the operation of the equipment, including starting, stopping, shear frequency adjustment, pressure setting and other functions. Modern hydraulic gantry shears usually use PLC control system, with a high degree of automation, simple operation, stable operation and other advantages, can realize the precise control and real-time monitoring of the equipment, but also for rapid fault diagnosis and alarm.Steel Plate Guillotine
Working Principle:
Hydraulic gantry shears work on the principle of hydraulic transmission. When the equipment starts, the oil pump starts to operate, the hydraulic oil in the tank is sucked and pressurized, and the high-pressure oil is transported to the hydraulic cylinder through the tubing. In the hydraulic cylinder, the high pressure oil pushes the piston, causing the piston to produce a linear motion, which in turn drives the movable blade connected to it. Driven by the hydraulic cylinder, the movable blade moves towards the fixed blade at a very high speed. When the scrap metal material is placed between the blade, the strong shear force formed by the movable blade and the fixed blade overcomes the shear strength of the metal, thus cutting the metal material. Throughout the process, the pressure, flow and other parameters of the hydraulic system are adjusted through the control system to achieve precise cutting of different specifications and materials.
Application Scenario:
1. Metal recycling processing: In the metal recycling industry, hydraulic gantry scissors is one of the core equipment. It can be recycled a variety of scrap metal materials, such as scrap steel, steel pipes, scraps, etc., according to the demand to cut into the appropriate size and shape, easy to follow the smelting, reprocessing, improve the recycling rate of metal.Gantry Shear
2. Scrap car dismantling: When dismantling scrap cars, hydraulic gantry scissors can quickly cut large metal parts such as the girder, chassis, engine shell of the car, disassemble the car into small pieces that are easy to transport and handle, improve the dismantling efficiency, and promote the effective recovery of scrap car resources.
3. Building demolition field: When demolishing buildings, a large number of scrap steel bars, steel beams and other metal structural parts will be produced. Hydraulic gantry shears can cut these metal materials to facilitate the cleaning of the site, and at the same time, the cut metal is recycled to achieve the recycling of resources.
4. Scrap metal pretreatment: For some large scrap metal equipment, mechanical parts, etc., before further processing, it is necessary to cut it into a suitable size with hydraulic gantry scissors for subsequent transportation, crushing or melting operations.Steel Sheet Cutter
