The above is the classification of the accessories on the hydraulic shear equipment. Here we remind the new purchaser that when receiving the hydraulic shears, they must check whether the accessories are complete according to the instructions, because these accessories are small, but they are essential , Do the check before use to confirm that we can use the machine faster.

Control requirements for hydraulic shears:

According to the working characteristics of the shears, the control requirements for the control system are as follows:

1. After power on, check the shape of each working mechanism and control each working mechanism to be in the initial shearing machine.

2. Feeding, the feeding mechanism is controlled by the control system to automatically transport the material to be cut into place.

3. Determine the cutting size, and use the servo motor to control the position of the stopper to ensure the accurate cutting size. However, the size of the shearing machine may also be configured as a cycle change value.

4. Pressing and cutting. After the length of the cut sheet reaches the set value, the main motor will blow the presser and the cutting tool to first compress the sheet and then cut the sheet.

5. The operation of the feeding car, including automatic return after unloading.

6. The size setting, automatic counting and pre-setting of the number of sheets per car.

7. With power failure protection and power recovery output.

8. It can complete the automatic control of the processing process, reveal the processing parameters, and check the system.

9. Ensure the accuracy of sheet metal processing, processing function and stability.

10. Has an excellent man-machine interface.


Adjustment of the baffle of the hydraulic swing beam shears:

1. Adjust the angle baffle

First put the template on the table to align the lower knife edge, adjust the angle baffle and fix it, then adjust the back baffle according to the template, use both the angle baffle and the back baffle to position during the cutting process.

2. Adjust the rear baffle

Align the template support level with the lower knife edge, and then close the back baffle to the template and fix it, remove the template, and then install the sheet for cutting.

3. Adjust the front baffle

Put the rear baffle close to the lower knife edge, then put the template close to the rear baffle, and fix the front baffle close to the template. Loosen the back baffle, remove the template, install the sheet, and cut.

The performance requirements of CNC shearing machine oil for shearing machine oil are as follows:


The first point: the viscosity of hydraulic shearing oil: moderate viscosity is better, too much will increase the viscosity of the flow resistance in the pipeline, the shearing machine is too small, or affecting the shear lubrication conditions will also cause the wear of the shearing hydraulic components. The volumetric efficiency has dropped.

The second point: good lubricity and wear resistance: a good shear hydraulic oil must have good lubricity and wear resistance. Shearing machine manufacturers make more coordination of lubrication and avoid friction and shear wear between hydraulic components.

The third point: good shear stability: in order to increase the viscosity with the wild, the hydraulic oil of the hydraulic pendulum shears is added in the shearing of the polymethacrylate, the molecule is determined by the material of the hydraulic shears , Through this reaction, to increase the shearing capacity of the hydraulic oil of the guillotine shears.

Fourth point: Shearing machine hydraulic oil emulsion and anti-foam in two aspects. A mixture of an emulsion of water and oil to separate water. Anti-foaming bubbles in the fluid are mixed with the generated water.

Several characteristics of pendulum shears:


1.Is a hydraulic drive, pendulum tool post, the frame is welded solid and durable, and the accumulator oil cylinder used has a smooth and rapid return.

2.Is hydraulic upper transmission type, stable and reliable

3.Is that the rolling support device can reduce the friction while ensuring that the surface of the workpiece is not scratched.

4.It has the function of stepless adjustment of the stroke. The upper knife has two blades and the lower knife has four blades. The gap between the upper and lower blades is adjusted by the handle, and the uniformity of the blade gap is easy to adjust.

5.The press plate of the machine tool adopts independent hydraulic press tools, and the end of each press tool has plastic feet.

6.Is an all-steel welded structure, vibration eliminates stress, high strength and good rigidity

7.Is the numerical control system E20 of the special shearing machine for the back gauge. There is a digital display device for the cutting times.

8.Is the protective barrier and electrical interlock to ensure safe operation.

9.Is a hydraulic drive, pendulum-type tool rest, the frame is welded as a whole and durable, and the return stroke of the accumulator cylinder is smooth and rapid.


Shearing machine is a kind of forging machinery. Its main function is the metal processing industry. It is a machine that uses one blade to perform reciprocating linear motion relative to the other blade to cut sheet materials. It uses a moving upper blade and a fixed lower blade. Reasonable blade gap, applying shearing force to various thickness of sheet metal materials, so that the sheet materials can be broken and separated according to the required size.

Classification of shears:

1. According to the power principle, it can be divided into: mechanical shears and hydraulic shears.

(1) The mechanical shearing machine adopts a resistance key form of clutch structure and an open gear transmission, and adopts more advanced electrical operation. The all-steel welding structure is simple, easy to operate, beautiful in appearance, and low energy consumption. (2) The hydraulic shear is beautiful in appearance , Excellent performance and stable quality. It uses a moving upper blade and a fixed lower blade to apply a shear force to metal sheets of various thicknesses by using a reasonable blade gap, and the stone sheets are broken and separated according to the required size.


2. According to the movement mode of the upper blade, it can be divided into: swing shears and gate shears.

3. According to the operation mode, it can be divided into: ordinary shearing machine and CNC shearing machine.

(1) Ordinary shears are mechanical operations that need to be carried out manually; (2) CNC shears generally use general-purpose or special-purpose computers to achieve digital program control, and they usually control mechanical quantities such as position, angle, and speed. The energy flows to the relevant switch. The production of CNC shears relies on the emergence of data carriers and binary data operations.

Working principle of shearing machine: After shearing, the shearing machine should be able to ensure the straightness and parallelism requirements of the shear surface of the sheared sheet, and minimize the distortion of the sheet material to obtain high-quality workpieces. The upper blade of the shearing board is fixed on Taoism, and the lower blade is fixed on the workbench. A material holding ball is installed on the worktable to prevent the sheet from being scratched when sliding on it. The back gauge is used to fix the plate, and the position is adjusted by a motor. The pressing cylinder is used to compress the sheet material to prevent the sheet material from moving during cutting. The guardrail is a safety device to prevent industrial accidents. The return journey generally relies on nitrogen, which is fast and has little impact.


Precautions for using shears:

1. Start the shearing machine to work idling for several cycles to ensure that under normal conditions, test cuts of different thicknesses, from thin to thick.

2. The gap between different blades must be adjusted when trying to cut sheets of different thicknesses. If the corresponding blade gap is not adjusted, the blade durability will be affected.

3. Turn on the pressure gauge switch during the cutting process and observe the oil pressure value. The pressure should be less than 20MPa when cutting a 12mm plate.

4. There is sound during operation, stop and check

5. When the shearing machine is operating, the temperature of the fuel tank is raised to less than 60 degrees, and it is necessary to shut down and rest.
