The pressurization process usually binds the metal plate onto the pressurizer, rotates with the main axis and cores, and then puts pressure on the spinner. This partial plastic deformation is gradually extended to the whole fabric, thus acquiring the hollow rotor parts of various shapes。
Rotate processClassification and characteristics
The spin process is usually divided into pull-deep, shearing (convene to thin voltage), barrel to thin voltage, neck harvesting, swelling, cutting sides, curly sides, crushing bands, and surface fineness。
By process
Rotation processes can take the form of cylinders, cones, parabolics or various other curves, as well as the processing of parts of rotary bodies of fairly complex shapes。
Rotation-forming applications are wide, with rotors being able to work with a pressurized process; the disadvantage is that it is less productive and is more suitable for experimental and small-volume production, generally exceeding 1,000 units, and the cost of production of rotors exceeds the charge。
The share of the voltage process material is larger in carbon steel, aluminium and stainless steel than in zui
Many metal materials are suitable for rotor processing, mainly:
Carbon steel
Aluminium, aluminium alloy
Stainless steel
Copper, brass
Nickel alloys
Titanium, molybdenum, tungsten, tantalum, neon, etc
Among them, carbon steel, aluminium and stainless steel account for more than zui and exceed 80 per cent of the total processed material。

Lubrication and cooling processes
Common lubricants are as follows:
Mechanical oil
Soap
Paraffins
Lubricose
Mixed oil
Water soluble oil
Spray
Rubber zinc
Molybdenum disulfide
When a normal voltage is formed, the rotor is in contact with the work, which is fluid lubrication and therefore less stringent for lubricants。
In order to reduce deformative resistance and improve surface quality, constant use of lubricant is required for thinning。
Attention:
When fluid lubricants are used, the greater the velocity of hair and the diameter of the wheel, the smaller the velocity and pressure of the wheel, and the smaller the viscosity factor of the lubricant, the better the lubrication effect. When coated, it is necessary to apply evenly to avoid grafts on the surface of the product。
Client production processing
The customer produces stainless steel products, raw materials of 0. 8 mm thickness, stretching to 160 mm depth and hand-painting lubricants。
Problems
The normal mechanical oil lubricants are limited and the product surfaces suffer from pull。
In some cases, the oil is less sticky and is thrown out when the core model rotates at high speed。
In some cases, the oil is of high viscosity and uneven paint, affecting product quality。
Solutions
The customer used the oil for low viscosity and limited lubrication, requiring six brushes throughout the process. Based on its feedback, the company recommends suitable viscosity and lubricant products. (form dp 60)。
Use effects
The original use of oil lubricants was limited, requiring six brushes throughout the processing process and one or two brushes after replacing the company's oil。
