The forging of flange industry as a mechanical base flange is not a simple mechanical component in the usual sense, it is a mechanical product carrier which contains a rich technical connotation. Both manufacturing methods belong to the stainless steel flange commonly used manufacturing methods, see the need to use the strength of the components, if the requirements are not high, you can also choose not to have advanced forging flange technical level of the national value. Industry, its technical level, to a country’s industrial and technological development of water home, it is difficult to say is a use of turning flange. Forged flanges Use important standard process production, and can adopt important standard conditions, andraeanum the user’s use demand, has the important significance and the price flat to have the representative significance in the important way processing process. A country that does not have a forged flange industry is not a fully industrialized country, then a country with advanced manufacturing technology. Forged flange quality is better, generally through the production of Die forging, crystal microstructure, high strength. Forging method,
Forging flange and other processing methods used most of the stamping method, forging method, roller processing, rolling, bulging, stretching, bending, and combined processing. Tube processing is the organic combination of machining and metal pressure processing.
Forging method: The use of forging machine will be beveling part or part of the extension, so that the outside diameter is reduced, common type forging machine has rotary, connecting rod type, roller type.
Stamping method: In the punching press with tapered core to extend the pipe end to the required size and shape.
Roller method: Placing the core in the tube, the external circumference of the wheel push pressure, used for the processing of the rim.
Rolling method: Generally without mandrel, suitable for thick wall tube inside round edge.
Bending Forming method: There are three methods are more commonly used, one method is called stretching method, another method is called pipe stamping method, the third is familiar with the roller method, there are 3-4 rollers, two fixed rollers, a adjust roller, adjust the fixed roller spacing, finished pipe is curved. This method is widely used, and if the spiral tube is produced, the curvature can be increased.
Bulging method: One is to place rubber in the tube, the upper part is compressed with a punching, and the pipe is bulging and forming; Another method is the hydroforming of pipe fittings, filled with liquid in the middle of the pipe, and the pressure of the tube to drum into the desired shape, like the production of the corrugated pipe we use most of this method.
