Working principle of hydraulic plate shears

Working principle of hydraulic plate shears

Hydraulic plate shearing machine is a kind of plate shearing machine driven by hydraulic pressure. With the help of the moving upper blade and the fixed lower blade, a reasonable blade gap is adopted to apply shear force to the metal plates of various thicknesses, so that the plates are broken and separated according to the required size. What this article will introduce to you today is the working principle and operating procedures of the hydraulic plate shears? If you want to know about children’s shoes, please follow me to have a look!

The main performance characteristics of the hydraulic bending machine are:

1. The hydraulic bending machine is welded by high-quality steel plates. The welded parts are stress relieved by vibration. The machine has high strength and good rigidity, and the frame can be stable for a long time.

2. The piston of the main cylinder of the hydraulic bending machine adopts aerospace technology – surface nickel phosphorus treatment, and its hardness can reach above HRC60. The guide sleeve that moves relative to the piston adopts zinc based wear-resistant alloy with self lubrication, which can make the cylinder in good working condition for a long time.

3. It adopts torsion shaft synchronization and mechanical stop, which is reliable, economical and high precision.

4. The distance of the rear stopper and the stroke of the upper slider are electrically adjusted, manually adjusted and digitally displayed.

5. The upper die is equipped with a winding compensation mechanism.

Working principle analysis of hydraulic bending machine if we want to design the plate shears perfectly, we must consider all the factors, the advantages and characteristics of the pendulum plate shears Zibo bending machine manufacturer found that with the continuous improvement of computer level and the increasing demand of modern industry for multiple varieties and small batch production, the accuracy and high… In recent years, the industrial enterprises have developed rapidly, and the plate shears have played an important role in this rising process. Through specific analysis, the hydraulic plate shears are a kind of plate shears that adopt hydraulic transmission and borrow blade clearance, A hydraulically driven plate shearing machine for shearing plates of various materials.

The hydraulic bending machine mainly includes a bracket, a workbench and a clamping plate. The working principle of the hydraulic bending machine is that the coil is electrified by the wire during use, and the pressure plate is attracted by the electrified wire, so as to realize the clamping of the thin plate between the pressure 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 walls can be processed. The operation is also very simple.

Operating procedures of hydraulic swing plate shears:

1、 Carefully implement the relevant provisions of the general operating procedures for forging equipment.

2、 Carefully implement the following supplementary provisions:

Instructions before work:

1. Before the no-load operation test run, manually turn the machine for one working stroke, and then start the equipment after it is confirmed to be normal.

2. For equipment with hydraulic device and oil storage tank, the oil quantity shall be sufficient. After starting the oil pump, check whether the valve and pipeline have leakage, and the pressure shall meet the requirements. Open the air release valve to release the air in the system.

Notes during work:

1. It is not allowed to cut the laminated plate, trim the edge of the rough edge plate, and cut the narrow plate and short plate that are not tightly pressed.

2. The clearance between the cutter plates shall be adjusted according to the thickness of the plate, but shall not be greater than 1 / 30 of the plate. The knife plate shall be fastened firmly, and the upper and lower knife plate surfaces shall be parallel. After adjustment, manual turning shall be applied for inspection to avoid accidents.

3. The cutting edge of the blade shall be kept sharp. If the cutting edge is blunt or cracked, it shall be replaced in time.

4. During shearing, the pressing device shall firmly press the sheet, and it is not allowed to shear under the condition of not pressing tightly.

5. For equipment with hydraulic device, other hydraulic valves except throttle valve shall not be adjusted without permission.

6. The thickness of the plate sheared by the hydraulic pendulum plate shears shall be determined according to the relationship curve between the ultimate strength of the plate and the plate thickness.

After working, the upper blade shall be placed at the lowest position.
