1、Turn on the power ：
Before using the bending machine we need to manually turn on the power supply, the specific operation of the bending machine on the control panel to open the power switch, and then immediately after the start of the oil pump, when the oil pump is successfully started after we will hear the sound of the oil pump rotating, rotating normal on behalf of the bending machine can work normally.
2、Test Stroke
When the bending machine can start normally after we need to test the bending machine to ensure that it can normally complete the work, this step is called the stroke adjustment, the specific operation is to test the upper die down to the bottom to ensure that there is a gap in the thickness of the plate, because this ensures that it will not cause damage to the bending machine molds, to extend the use of its cycle. It should be noted that the stroke adjustment is divided into automatic adjustment and manual adjustment, the user can choose according to their own behavior.
3、Determine the size of the slot
After the test adjustment, the user needs to choose the size of the bending notch, according to the cutting standards to determine the plate, in general, you can choose the thickness of the plate 8-10 times the width of the notch, a slight difference between different machines. For example, to bend 5mm sheet, then you need to 40mm or 50mm size of the groove.
4、Bending machine rear stopper adjustment
First confirm that the backstop is accurate, the specific operation is to confirm that the mold and program data is consistent, bending product data, size is unified.
- Pedal can bend the plate
After placing the sheet, you can start bending the product by stepping on the bending machine, and if you need to pause the bending, just step on the bending machine again.

5.The use of the finished bending machine needs to be checked, maintenance, maintenance.
Summary:
The use of bending machines must be strictly in accordance with the operation of the use of process specifications for bending products, so as to ensure that the service life of the bending machine as well as for the enterprise to save a lot of unnecessary operating costs, and of course, more importantly, to ensure that the user’s own production safety.
CNC bending machine maintenance maintenance specification：
CNC bending machine is a kind of machinery and equipment commonly used in modern industry. In order to ensure its normal operation and extend the service life, the CNC bending machine for regular maintenance is very important.This article will be from the CNC bending machine routine maintenance, lubrication, electrical parts and safe operation of the CNC bending machine maintenance specification in detail.
Routine maintenance：
- Regularly clean the external surface of the CNC bending machine, the internal parts and the waste chip collector, and keep the environment around the machine clean.
- Regularly check whether the parts are loose, if found loose should be tightened in time.
- Regularly clean dust and oil from the CNC bending machine and spray oil on the lubrication points.
- Check all connections and power cords for proper functioning and replace them if damaged.
- Check whether the hydraulic system and electrical system of the CNC bending machine are normal, if abnormalities are found, they should be dealt with promptly.
Lubricating machines：
- Regularly lubricate the lubrication points of the CNC bending machine, use the right amount of lubricant and make sure the oil is clean
- Lubrication points include slides, sliders, fork arms, manipulators and other components, and the lubrication cycle is generally after the end of each shift of operation or daily lubrication.
- The choice of lubricant should be based on the use of the machine environment and requirements, in the process of use should pay attention to whether the oil level is normal and whether the oil is clean, regular replacement of lubricants.
electrical part：
- Regularly check the electrical connections of the CNC bending machine to ensure that the wire connectors are tight and reliable, the electrical components work properly, and that they are well protected.
- Regularly check whether the electrical control system of the CNC bending machine is normal, if abnormalities are found, they should be dealt with in a timely manner or replace the faulty components.
- Regularly check the sensitivity and reliability of the sensors, limit switches and other electrical components of the CNC bending machine, and clean or replace them in time if any abnormality is found.
safe operation：
- Operators must be familiar with the operating procedures and safety specifications of CNC bending machine, it is strictly prohibited without training personnel to operate CNC bending machine.
2.Operators must wear safety equipment such as helmets, goggles, and protective clothing.
3.Operators should remain focused when operating the CNC bending machine and should not leave or divert their attention without authorization to avoid accidents.
4.The operator should pay attention to the operation of the machine at any time, if abnormalities are found, it should be immediately shut down for maintenance.
The above is the maintenance specification of CNC bending machine, through regular maintenance can ensure the normal operation of CNC bending machine and extend the service life.
Hazards of hydraulic fluid contamination
Serious contamination of the oil will directly affect the performance of the hydraulic system, and even more terrible is that it will lead to frequent failure of the braking system and shorten the life of the hydraulic bending machine components. The main cause of these hazards is the particles in the dust, and in the case of hydraulic components, these solid particles entering the components increase the wear on the sliding parts of the components. In addition, it can clog throttle orifices, blockage holes in hydraulic components, or stuck spools, leading to hydraulic system failure.
In addition, the mixing of water and air reduces the lubrication of the hydraulic fluid and accelerates its oxidation, producing cavitation corrosion. As a result, accelerated corrosion of hydraulic components can cause vibration, noise, etc. in the hydraulic oil system of the press. In order to extend the service life of the hydraulic system components, to ensure the reliable operation of the hydraulic system, the hydraulic oil pollution control within a certain range of feasible.
Keep hydraulic pressure clean before use：
Hydraulic fluids are susceptible to contamination during transport and storage, and a newly purchased hydraulic fluid that looks clean is actually dirty. It must be allowed to sit for a few days and then filtered into the hydraulic system for use.
Keep oil clean before transporting after equipping：
The CNC bending machine tank must be kept clean during the manufacturing process, in addition, the hydraulic system should be thoroughly cleaned after assembly and before operation. Therefore, after the manufacturing and assembly are completed and the test run is satisfactory, we will empty the hydraulic fluid from them before they are shipped to the user. This ensures that the hydraulic fluid does not leak or become contaminated during transport. After the machine is delivered to the user, the customer is taught to install, add hydraulic fluid and run the machine again.
Keeping clean at work：
During the use of CNC bending machine, the hydraulic oil will be polluted by the environment, so we have to prevent the intrusion of air and water. To completely eliminate the intrusion of water, gas and contaminants, use a completely sealed tank. Add air filters to the ventilation holes to keep out dust, abrasives and coolant. However, users still need to regularly inspect and replace seals and use proper oil filters as an important means of controlling hydraulic fluid contamination. The oil filter and tank must also be checked and cleaned regularly.
Regularly change the hydraulic oil：
The hydraulic oil must be checked and changed regularly and the tank must be cleaned before filling it with new oil.
Controlling the temperature of hydraulic machine oil：
High operating temperatures of the hydraulic fluid are harmful to the hydraulics. In addition, high temperatures accelerate the deterioration of the oil itself, producing a variety of products that shorten its service life. The working temperature of all hydraulic systems should preferably be below 65℃, and the hydraulic system of CNC bending machine should be controlled below 55℃.
