What should be prepared before using press brake?
How to operate press brake?
What are the warnings when using press brake?
When operating the press brake, in order to prevent the occurrence of problems, the preparations must be carried out.
Clean the oil stains on the appearance of press brake. The engraved line on the stop valve should be in the open position.
Turn on the press brake for a few cycles, ensuring that there are no abnormal conditions. Try cutting different thickness sheets. During trial cutting, the gap between the different blades must be adjusted because the thickness of the plate is different. Otherwise, the durability of the blade will be affected.
During the cutting process, turn on the pressure gauge and check the oil pressure value. If any abnormality, the relief valve can be dispatched to meet the specified requirements.
When operating the press brake, if abnormal noise or overheating of the oil tank is found, the press brake should be stopped and checked. The high temperature of the fuel tank does not exceed 60 degrees.
Turn on the press brake power and the key switch on the control panel. Then, press the oil pump to start.
The press brake must pay attention to the adjustment stroke. Be sure to test before operating. When the upper die of the press brake descends to the bottom, there must be a gap of plate thickness. Otherwise, it will cause damage to the mold and the press brake. The stroke adjustment also has electric quick adjustment and manual fine adjustment.
For the selection of bending notches, a notch with a width of 8 times the thickness of the plate should generally be selected.
Backgauge adjustment generally has electric quick adjustment and manual fine adjustment, which is the same as the shearing machine.
Step on the foot switch to start bending. You can release it at any time.
Before operating the press brake, check whether the motor, switch, circuit and grounding are normal and firm. Check that the control parts and buttons of the press brake are stuck in the correct position.
Check the firmness of the upper and lower molds that whether each positioning device meets the processing demands.
If the upper slide plate and each positioning axis are not at the origin, run the return-to-origin program.
After the press brake is started, run idling for 1 to 2 minutes, and move on the skateboard 2 to 3 times at full stroke. Troubleshoot the malfunction until press brake is normal.
The operator should be in uniform command, cooperating closely with the feeding and suppressing operator.

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.

Laser cutting machine has become an indispensable tool for metal sheet processing enterprises. However, when using laser cutting machine for processing, we encounter some problems, like the large gap of steel plate and the reduced accuracy of the processed components.
A lot of heat will be generated, which may deform the surface of the thin plate and the processed workpiece.
The focus of the laser cutting machine and the surface of the processed object change, causing the large cutting gap or inaccurate processing.
An error will occur due to the incorrect position of the worktable. If the laser cutting machine is not installed firmly and the parts are worn for a long time, the worktable surface will be uneven. This imbalance will also cause problems between the thin steel plate and the laser focus, resulting in excessive cutting gaps or reduced processing accuracy.
One of the biggest advantages of laser cutting machine is to cut a wide range of materials.
Laser cutting machine can cut all types of metals, ranging from mild steel to stainless and non-ferrous metals. More reflective metals like aluminum are more difficult to cut. The thickness of the metal can be up to 30mm. The maximum thickness depends on the laser cutting machine.
Different types of wood are suitable for cutting like plywood and MDF. However, be aware of oils or resin to avoid fire.
Paper and cardboard are also suitable for laser cutting machine, where the popular wedding invitations are made.
Plastics also leave a great finish when using laser cutting machine that the edges are melted in a polished way.
POM is a highly utilized plastic in the engineering sector, finding usage in gears, guiding and sliding elements, medical instruments, and food packaging. It can also be cut by laser cutting machine.
Cutting glass is a seemingly impossible task because of its fragile and reflective properties. However, laser cutting machine can engrave glass.
Replace the circulating water once a week. Make sure that the laser tube is filled with circulating water before the laser cutting machine works. It is recommended to use pure water and keep the water temperature below 35°C.
Long-term use of the fan will accumulate a lot of solid dust, making the fan generate a lot of noise and not conducive to exhaust and deodorization. Disassemble the air inlet and outlet pipes on the fan. Remove the dust inside. Turn the fan upside down and pull the inner blades until they are clean.
It is recommended to clean lens before laser cutting machine works every day. There are 3 mirrors and 1 focusing mirror on the machine. The lens are easily stained with dust or other contaminants, which can cause laser loss or damage to the lens. Just rotate to wipe from the center to the edge with the lens wiping paper.
After the motion system has been working for a period of time, the screws and couplings at the motion connection will loosen, which will affect the smoothness of the mechanical motion. Observe whether there are abnormal noises or phenomena in the transmission components.
