Shearing machine is very important in the era of scientific and technological development. In terms of work efficiency, many enterprises have seen the light in the production of finished products due to shearing machine. They play a very important role in processing such as metal and non-metal plates.
Why is shearing machine widely used?
What is the structure of shearing machine?
How does shearing machine work?
The shearing machine plays a role in fast cutting for some panels that need to be processed. The traditional cutting wood is more often used by the see-saw method, which has slow speed and makes people tired. The saw blade is very easy to wear and break. However, the use of shearing machine gives a feeling of high efficiency, convenience and the high quality. Because the shearing machine has two blades merged into one joint, which can be adjusted, it can be cut at any angle, even if the plate is bent and deformed.
The main structure of the shearing machine is generally composed of the body, the transmission system, the knife holder, the presser, the front stopper, the rear stopper, the supporting device, the blade gap adjustment device, the light alignment device, the lubrication device, electrical control devices and other components.
The shearing machine is welded by steel plate, which has good rigidity. The two cylinders are fixed on the left and right columns. The auxiliary tool holder is provided on the working table to facilitate the micro adjustment of the lower tool holder. There is also a feeding ball on the working table of shearing machine.
The upper tool holder is a steel plate welded structure. It uses the eccentric sleeve as the fulcrum to swing back and forth under the drive of the left and right oil cylinders and the accumulator return cylinder to complete the shearing. The vertical supporting surface of the blades of shearing machine forms an arc-shaped curve to ensure the consistency of the gap between the upper blades during the cutting process.
The material pressing device is composed of several material pressing oil cylinders installed on the front supporting surface of the frame. The head presses down after overcoming the tension of the relay spring to compress the sheet material. It resets by the pulling force of the tension spring.
The shearing machine should be able to meet requirements of the straight and parallel shearing surface of the sheared sheet. Shearing machine should minimize the distortion of the sheet to obtain high-quality workpieces. The upper blade of the shearing machine is fixed on the knife holder, while the lower blade is fixed on the workbench. A holding ball is installed on the workbench so that the sheet material will not be scratched when performing. The back gauge is used for positioning the plate that the position can be adjusted by the motor. The pressing cylinder is used to compress the sheet to prevent the sheet from moving during shearing. The guardrail is a safety device to prevent work-related accidents. The returning generally relies on nitrogen, which is fast and has little impact.
The movement of the shearing machine is that the belt on the motor transmits the torque to the large pulley shaft. The large pulley shaft has a small gear at the other end. The power is transmitted from the small gear to the large gear on the shearing shaft. The large gear shaft is equipped with a clutch mechanism. When the shearing machine is operated, the large gear drives the shearing shaft. The eccentric wheel on the shearing shaft drives the upper knife holder to move up and down linearly through the connecting rod to shear.

An efficient press brake is fundamental to avoiding damages and detecting failures. Keeping press brake clean and tidy is simple but important. It should be done the daily, weekly, monthly, and yearly.
Why does press brake leak oil?
What should you do for oil of press brake?
What is the role of oil of press brake?
The sealing ring is not suitable for the conditions of using press brake. The O-shaped rubber seals often used in press brake must be selected according to the operating conditions and working conditions. Under oil lubrication conditions, the hardness of the oil-resistant rubber O-ring seal can be low hardness when the oil pressure is less than 2.9MPa. When the oil pressure is 2.9 to 4.9MPa, medium hardness should be selected. When the oil pressure is 4.9 to 7.8MPa, select high hardness.
There is no design seal or unreasonable seal structure. The screw hole on the body of the press brake is designed as a through hole with no sealing measure. The press brake cover is not designed with a gasket. The clearance between the shaft and the body hole is too large. The interference between the sealing ring and the shaft does not meet the requirements. The design of sealing groove is unreasonable.
Oil leakage can be caused by casting defects and parts damage. The castings of the press brake have defects such as blisters, pores, cracks, and loose tissues. When the oil pipes and pipe joints of the press brake are made of plastic or oil-resistant rubber, the materials will age to become hard and brittle after long-term use. The moving parts will lose the sealing performance due to friction and wear. If the gap between the shaft and the shaft hole increases, it will also cause oil leakage.
Before maintaining or cleaning, the upper mold should be aligned with the lower mold. Shut down until the work is completed. If you need to start press brake, select the manual mode to ensure safety.
Check the oil level of the oil tank every week, even after the hydraulic system is repaired. If the oil level is lower, add hydraulic oil. The oil should be changed after 2000 hours of operating new press brake. Afterwards, the oil should be changed after 4000 to 6000 hours of operating press brake. The oil tank should be cleaned every time before changing the oil. The oil temperature of the press brake should be between 35℃ and 60℃ that is not exceed 70℃. Otherwise, it will cause deterioration and damage of the oil quality and accessories.
The filter of press brake should be replaced or thoroughly cleaned every time if the oil is changed. If the press brake has filter abnormalities such as unclean oil, the filter should be replaced. The air filter on the fuel tank should be inspected and cleaned every 3 months and replace every year.
After using the new press brake for one month, check whether the bending of each oil pipe is deformed. After two months of use, all fittings should be tightened.
The oil of the press brake plays the role of transmission, wear resistance, system lubrication, anti-corrosion, rust prevention, and cooling in the hydraulic system. It belongs to the industrial hydraulic system. The hydraulic oil itself is constantly changing in use. However, it is difficult to completely solve the problem of hydraulic oil pollution.
Serious oil pollution will directly affect the performance of the press brake. It will cause frequent failures of the brake system and shorten the lifespan of press brake.
The main reason is the particles in the dust. As far as hydraulic components are concerned, these solid particles entering the components will increase the wear of the sliding parts. In addition, it may block the orifice, the orifice in the hydraulic component, or the spool stuck, causing the hydraulic system to malfunction.
The mixing of water and air reduces the lubrication of hydraulic oil, accelerating the oxidation of hydraulic oil and producing cavitation corrosion.

The steel bent by the CNC press brake has a relatively large advantage over the others. Because the residual stress of the steel material of the CNC press brake is relatively small with dense weld seam. The CNC press brake in the production practice produces section steel with very messy interface shapes, which is impossible for traditional processes.
