The hydraulic plate shears must be operated in strict accordance with the operating rules to ensure the safety of personnel

Hydraulic shearing machine according to its tool rest movement is divided into linear and swing type.Straight-line structure is relatively simple (such as gate, so it is also called gate), easy to manufacture, the blade section is rectangular, four edges can be used as the blade, so it is more durable.The tool rest of pendulum hydraulic plate shears according to its tool rest movement is divided into linear and swing type.Straight-line structure is relatively simple (such as gate, so it is also called gate), easy to manufacture, the blade section is rectangular, four edges can be used as the blade, so it is more durable.The tool rest of pendulum plate shearing machine swings around a fixed point when shearing. It has the advantages of small friction and wear between upper and lower cutting edges, small blade deformation and high shearing accuracy.

The working principle of the hydraulic system of the cnc hydraulic shearing machine: the sheet material is positioned by the retaining cylinder. After the positioning, the electromagnet is energized, and the electromagnetic relief valve stops discharging oil.The oil discharged by the hydraulic pump enters the press cylinder, supporting cylinder and retaining cylinder through the pressure reducing valve and one-way valve.The pressing cylinder compresses the sheet material, the supporting cylinder returns, and the piston of the retaining cylinder leaves the sheet material under the action of differential pressure. Its right chamber drains oil to the accumulator, while the hydraulic pump fills liquid to the accumulator.The press force is adjusted by the pressure reducing valve.When the pressure rises beyond the adjustment pressure of the one-way sequence valve, the high pressure oil enters the upper chamber of the shear cylinder and realizes the shear action.The role of the accumulator is to supplement the leakage of oil in the pressure loop, and reduce the power consumption when the cutter head is down, and reduce the heat of the system.In addition, the one-way valve can be kept open, the pressure of the hydraulic pump can be determined by the actual resistance of the air travel, and the energy consumption is significantly reduced.

Hydraulic shearing machine press circuit pressure by three aspects to ensure:

Accumulator to compensate for leakage,

Second, by hydraulic pump through the pressure reducing valve oil supplement,

Three rely on pressure reducing valve and solenoid relief valve to limit its working pressure.

The hydraulic shearing machine needs to be operated in strict accordance with the operating rules;Add lubricating oil at regular time, fixed point and quantity according to the requirements of lubrication chart before starting each time, and the oil should be clean without precipitation;Machine tools need to be kept clean, unpainted parts of antirust grease;And regularly check the triangle belt, handle, knob, button is damaged, serious wear should be replaced in time, and reported for spare parts supplement, regularly check repair switch, insurance, handle, to ensure its reliable work;Non-designated personnel are strictly prohibited to operate the equipment. People usually need to leave the machine and stop.

The main classification

Special plate shears

Cooperate with other equipment to complete special purposes:

1, cold-bending molding line shearing machine: such as car rail cold-bending line, carriage side baffle production line, color steel plate forming line and other production lines configured on the special shearing machine;

2, steel structure production line shearing machine: mostly used for Angle steel, H-beam automatic production line to complete the cutting process;

3, plate open line shearing machine: used for plate uncoiling and leveling line, high speed plate shearing machine designed to meet the requirements of production line speed fast shearing, thick plate line for hydraulic high-speed shearing machine, thin plate line with pneumatic shearing machine;High-speed line equipped with flying shear machine, continuous production, high efficiency.

Slant blade shears

The upper and lower two blades of the plate shearing machine are at an Angle. Generally, the upper blade is inclined, and the inclination Angle is generally 1° to 6°.The shearing force of the inclined edge shearing machine is smaller than that of the flat edge shearing machine, so the power of the motor and the weight of the whole machine are greatly reduced. The actual application is the most, and the shearing machine manufacturers produce more such shearing machines.

Flat edge plate shears

The shear quality is good, the distortion is small, but the shear force is large, the energy consumption is large.Mechanical transmission is more.The upper and lower blades of the shearing machine are parallel to each other. They are often used for hot shearing of rolling billets and slabs.According to its cutting mode, it can be divided into upper cutting type and lower cutting type.

Multi-purpose plate shears

1. Combined punching and shearing machine: it can complete the shearing of the plate and the shearing of the profile. It is mostly used in the blanking process.

2, sheet bending shear machine: that is, in the same machine can be completed on the shear and bending two kinds of process.

The working principle of

After shearing, the shearing machine should ensure the straightness and parallelism of the shearing surface of the shearing plate, and minimize the distortion of the plate, so as to obtain high-quality workpieces.The upper blade of the shearing machine is fixed on the tool rest, and the lower blade is fixed on the workbench.A supporting ball is installed on the work table so that the sheet material will not be scratched when sliding on it.The rear stopper is used for sheet positioning and the position is adjusted by the motor.The press cylinder is used to press the sheet material to prevent it from moving during shearing.A guardrail is a safety device to prevent accidents at work.Return generally by nitrogen, fast speed, small impact.
