the hydraulic shear

the hydraulic shear is a kind of hydraulic driven plate shears. With the aid of the moving upper blade and the fixed lower blade, a reasonable blade gap is used to exert shear force on metal plates of various thicknesses, so that the plates are broken and separated according to the required size. Today, this paper will introduce the working principle and operating procedures of the hydraulic shear? Want to know the children's shoes quickly with this small make up to have a look! the main performance characteristics of the hydraulic bending machine are as follows: 1. The hydraulic bending machine is welded by high-quality steel plate. The welding part is stress relieved by vibration. The machine has high strength and good rigidity, and the frame can keep stable for a long time. The main oil cylinder piston of the hydraulic bending machine adopts aerospace technology surface nickel phosphorus treatment, its hardness can reach above HRC60, and the guide sleeve which moves relative to the piston adopts zinc base wear-resistant alloy with self lubrication, which can keep the oil cylinder in good working condition for a long time. 3. Adopting torsion shaft synchronization and mechanical block, it is reliable, economical and high precision. 4. Electric adjustment, manual fine adjustment and digital display of the distance between the back stop and the upper slider stroke. 5. analysis of the working principle of the hydraulic bending machine, if we want to design a perfect shear machine,Zibo bending machine manufacturers have found that with the continuous improvement cnc drilling machine manufacturers of computer level and the increasing demand of modern industry for multi variety and small batch production, the accuracy and accuracy are high In recent years, the rapid development of industrial enterprises, in this rising process, the shear plays an important role, through the specific division.. hydraulic shear is a kind of hydraulic driving plate shears, which uses hydraulic transmission and uses blade clearance hydraulic straightening machine to shear plates of various materials. the hydraulic bending machine mainly includes bracket, worktable and clamping plate. The working principle of the hydraulic bending machine is that the coil is electrified by the wire when it is in use, and the pressing plate is attracted after being electrified, so as to realize the clamping of the thin plate between the pressing plate and the base. Due to the use of electromagnetic force clamping, the pressing plate can be made into a variety of workpiece requirements, and the workpiece with side wall can be processed, and the operation is very simple. carefully implement the. 1. Before the double drive plasma cutting machine idle running test run, the machine should be turned manually for a working stroke, and the equipment can be started only after it is confirmed to be normal. 2. For equipment with hydraulic device and check the oil quantity of oil tank, it should be filledFoot. After starting the oil pump, check the valve and pipeline for leakage, and the pressure shall meet the requirements. Open the bleeder valve to let the air out of the system. in the work, it is not allowed to cut the laminated sheet metal, trim the edge of the rough edge sheet metal, and do not shear the narrow and short sheet metal which is not tightly pressed. 2. The gap between the tool plates should be adjusted according to the thickness of the plate, but it should not be greater than 1 / 30 of the maximum plate. The cutter board shall be firmly fastened, and the upper and lower blade surfaces shall be kept parallel. After alignment, manual turning shall be used for inspection to avoid accidents. 3. The cutting edge of the cutter board should be kept sharp. If the cutting edge becomes blunt or cracks, it should be replaced in time. During shearing, the pressing device should firmly press the sheet metal, and it is not allowed to shear under the condition of not being pressed tightly. For equipment with hydraulic device, except throttling valve, other hydraulic valves are not allowed to be adjusted without permission. The thickness of the plate cut by the hydraulic pendulum shear should be determined according to the curve of the relationship between the plate ultimate strength and the plate thickness. after working, the upper tool plate should be placed at the lowest position. source: China encyclopedia.com
