The gate-type Hydraulic shearing machine uses a frame structure with all-steel welding. It has four angles, eight sides with a right-angle guide rail, high precision, good rigidity, and hydraulic pre-tightening. The whole hydraulic system adopts a two-way cartridge integrated valve and can be configured with a digital stroke display, photoelectric protection device, and portable table (convenient for changing the mold). The gate-type shearing machine has a double function of both the upper slider and the lower hydraulic pad, and the device can adjust the working pressure stroke in the specified range according to the process requirements. It is easy to operate with the centralized control button.

1. Use the whole welding frame structure and vibration aging treatment. The machine has good rigidity, high precision, and good precision retention.
2. Use a three-point supporting axle rolling guide rail. The upper tool rests and moves gaplessly in the rolling guide rail. Rotating the hand wheel can adjust the service life of the blade.
3. The movable blade support and four-legged long blade are provided for easy adjustment of blade gap uniformity, improve shear quality and prolong blade service life.
4. Use a tandem cylinder synchronization system. The machine is forced uniformly. Adjusting the flow of the tandem cylinder makes it very convenient to adjust the shear angle, which can meet the needs of different shear plate thicknesses.
5. Use a motorized rear stopper device and electronic counter. It is convenient to adjust the position of the rear stopper.

The swing-type Hydraulic shearing machine usually adopts inclined blade shearing. It has been widely used because of its simple structure, low failure rate, high shearing efficiency, and no distortion and warping after cutting. In the shearing process, as the tool rest does rotary movement, the angle and shearing gap of the swing-type shear will change.
The machine is a steel-welding structure. Hydraulic transmission, vibration to eliminate stress, and it has high strength and good rigidity. Hydraulic swing-type shearing machines do downward shearing movement, and nitrogen cylinder return by using the main cylinder (fixed on the wall panel). So simplified, the hydraulic system operates more stably—the upper tool rest of the swing-type shearing machine swings around a fixed axis in the shearing process. Through leverage, the fulcrum has little force, which can improve the shearing blade and machine life. The whole machine is in a compact structure and can electrodeless adjust the stroke of the upper tool rest, significantly improving the working efficiency.

The shearing machine, to obtain a high-quality workpiece, should be able to ensure the straightness and parallelism of the shear surface of the sheet after cutting and minimize plate distortion. The upper blade is fixed on the tool rest, and the lower is specified on the working table. Material supporting ball is set on the operating table, so the sheet material will not be scratched when sliding on it. The rear stopper is used for plate positioning, and the motor adjusts the position. The press cylinder compresses the sheet to prevent it from moving during shearing. The guardrail is a safety device to prevent accidents at work. The return usually depends on nitrogen, which is fast and has little impact.
