How to solve the problem of air bubble on the surface of bending machine?

When the surface of a part of the hydraulic cylinder of the bending machine moves relative to the gear oil, the steam dissolved in the gear oil is very easy to settle and generate bubbles. This kind of bubble cracks after being injected into the high-pressure area, and the ultra-high pressure micro injection and impact force continuously work on the surface of hydraulic cylinder components of the zigzag bending machine, resulting in cavitation on the surface of components. The cavitation standard of hydraulic cylinder of the eight character bending machine is related to the structure of hydraulic transmission system, the components of hydraulic cylinder of the eight character bending machine, the quality of gear oil, maintenance and repair.

Bending machine is a kind of equipment which uses hydraulic transmission technology to carry out working pressure production and processing. It can be used to carry out various forging and inhibiting forming processes. For example, forged steel, metal parts molding, plastic products inhibition and rubber products. Bending machine is the first batch of hydraulic transmission equipment.

At present, the hydraulic transmission has become the key transmission mode of working pressure processing equipment. Bending machine has become the key machine equipment of heavy machinery processing industry, aerospace industry, plastic and rare metal manufacturing industry.

The hydraulic control system of the bending machine changes the working pressure in key application scenarios. The system software pressure is too large, the total flow is large, and the output power is large. Therefore, it is necessary to improve the utilization rate of the output power of the transmission device to avoid the impact and vibration in the whole process of relieving the pressure, so as to ensure the safety factor and credibility.

According to the whole process of inhibition, the bending machine can rapidly reduce the speed and press gently, maintain the working pressure for a delay time, return pressure, terminate (random parts), working pressure, rate and working pressure, rate and basic working cycle system. The maintenance time can be adjusted. The hydraulic cylinder is suitable for steel parts, and must be in the position of surging, reversing and terminating. For example, when the sheet metal is stretched, it is necessary to improve the auxiliary fitness exercise, such as the rise, termination and working pressure return of the hydraulic cylinder. Sometimes it is necessary to restrain the hair embryo with the sleeve barrel to avoid the wrinkles nearby. The bending machine uses the large working pressure (tons) which can be output by the main electric actuator (main cylinder) in the main body-building movement as the key specification of the bending machine, and has been serialized for a long time.
