hydraulic fittings skills to use to explore

Tube hydroforming is divided into three basic types of industries: linear parts forming, with a boss or a twig parts forming, as well as parts forming the curve. Projections or twigs on the punch press with a certain degree of matching between the internal pressure back out to ensure that no bursting twig or wrinkled. Parts of the curve relative to the axis, the first CNC bender bent to the required shape, and then press-molded into a mold shown in Figure.
Tube hydroforming technology advantages and field of application is the development trend of total manufacturing lightweight product, process flexibility. Tube hydroforming hydraulic couplings technology is the production of hollow lightweight piece of advanced technologies for the manufacture of lightweight hollow class precision parts. For hollow tapered member, the traditional manufacturing process in general stamping for the first two and a half pieces and then welded into a whole. Tube hydroforming technology can be characterized by one member integrally formed along the axis of the hollow member section has changed.
Tube hydroforming technology advantages and stamping and welding process compared to the traditional, tube hydroforming technology has the following advantages: reduce weight, save material. Automotive sub-frame, radiator support and other typical products, hydroformed structural parts than stamping reduced. For a hollow shaft can be reduced, some parts can be reduced, reducing the number of parts and molds, reduce tooling costs. HV pieces often only require a mold, and most require multiple sets of stamping dies.
Car exhaust pipe in order to adapt the structure and function of the specific requirements of a catheter used in some cars very complex shape, not only in the axial sectional geometry different from a very different, but often the axis of three-dimensional curves. For this special shape of the profiled tube of the processing, if produced using conventional processing methods often requires many processes, and high cost, long life cycle. If using the hydroforming process, through rational design can often forming a mold cavity, as shown for the use of tube hydroforming process of production of the engine exhaust pipe. Compared with the casting, working life increased by 2 times, weight loss, shorten the development cycle.
Complex hollow shaft parts for tube bending or torsional loads bear the main shaft parts, you can use tube hydroforming process to produce hollow shaft transmission parts. Hollow structure not only can guarantee the power transmission capacity, and substantially reduce the overall weight, which is very important for the aerospace industry. Crank the engine crutches for Walker shows Germany with tube hydroforming manufacturing process Volcker engine crankshaft hollow crutches. Conclusion tube hydroforming technology in recent years has been widely used in industry, reducing the demand for quality and reduce costs but also promote the continuous development of the technology, the future prospects are very bright, very significant economic benefits, particularly in the automotive field will obtain a more lightweight wide range of applications.
