INNER HIGH PRESSURE HYDROFORMING MACHINE

The form of internal high pressure (also known as hydroforming) is the process of forming materials using extra-high pressure cream (100-1000mpa) and axis filling to attach bitumen to the form of the form through the internal organs using extra-high pressure (100-1000mpa). 1000mpa and the axial filler that connects the closure to the moulding cavity, creating complex hollow parts such as a tubular tube, a crooked tube and a multi-channel tube (1). The process is divided into three phases of filling, moulding and plastics: first, seal the pipes and injected liquid, then enlarge and complete them, finally, stamping. The technology can reduce the weight of components by 20-50%, the material utilization factor to 95-98% and use them in general as a substitute for traditional target welding.

Technology emerged at the end of the 20th century, when European and American companies (such as schuler, kawasaki-oil companies) long dominated the design and development of equipment, and at the beginning of the 21st century they entered the automotive industry, which was used in such easy quantitative structures as secondary frames, radiator poles. Domestic institutions, such as the Harbin industrial university, China, have been conducting research since 2000, gradually promoting its applications in aerospace, medical and other fields. Technological development is a high voltage (600-1000mpa), an intellectual trend and generates branches such as the process of welded pipes, thermal forms, etc.

The concept 
Hydroforming (hydro forming) is a hydraulic forming technology used as a billet for hydraulic pipes, which is used as a substrate for ultra-high voltage fluid and axial axis substrate to form into a molding cavity to form an artestructure. Forms of internal pressure are divided into three categories depending on the type of constituent components: (1) high pressure conversion in tubes;(2) high pressure forming in tubes of bending;(3) form of internal high pressure in multi-channel tubes.

The principle of equality
The principle of the internal pressure form is to insert the clamp into the forming cavity through the internal pressure and the axial additive material to form the artex. For axis components for the curve, the billets must be bent in advance before they approach the shape of the part and then pressed on the shape.
Strengths and applications
The design, with low internal content, high quality products, flexible product design and a short technological process with characteristics such as almost pure shape and green production, has been widely used in the field of easy quantification of cars. Thanks to efficient section design and wall thickening, many car components can use standard piping to create complex structural components of the structure through internal high pressure. It is obvious that the quality of products, brevity of production, etc., for most hydrophoric sequences only a convex shape (or hydroform pressure) is required, in which the rubber diaphragm on the hydroforming machine is usually curved, making it about 50% cheaper than the usual shape. In comparison with traditional stamped forms, which require multi-purpose operations, the form of hydroform can be formed in one step.

Compared to electrowelding material, hydraulic pipes have the advantage of being shaped as follows: Material savings, weight loss, general structural element can be reduced by 20-30%, and axis class components - by 30-50% : as in the case of the second rack of the sedan, the general press element weighs 12kg, at the internal pressure - 7-9kg, at the internal pressure - from 7 to 9kg, at the internal pressure - by 34%, on radiators - by 16.5 kg, in general - by 16.5 kg, in the case of the internal pressure - 11.5 kg and 24% less; reduction of further load on equipment and welding works; increase of strength and strength of the structure, increase of fatigue due to reduction of the welding point. The material utilization rate ranges from 95 to 98% compared to the components for welding; the reduction of production costs and 30% of the cost of mould.

Moulding technology

The technology is divided into three stages:
The first phase, the pipe filling phase, places them in the lower module, then closes it by filling it with liquid (and excluding gas), sealing both ends of the pipe with a horizontal stamp;
The second stage, the moulding phase, while the impact head at both ends of the pipe is compressed according to the established loading curve, directing the additional material inside, in combination with a combination of internal and axial supplements, to make the tube materials mainly closer to the mould;
The third phase is plastic plastic, as a result of which the increased pressure makes the excessive Angle of the zone completely attached to the form of artifacts necessary for the formation of the form, which, in fact, does not contain additional materials that can transform the pipelines at the moment, screen, elliptical or other curved sections on the section.
