Composite inner and outer hydraulic pressure forming method for high-branch height thin-wall three-way pipe
ActiveCN102921792AReduce frictionImprove axial critical wrinkling stressInternal pressureHigh pressure
The invention discloses a composite inner and outer hydraulic pressure forming method for a high-branch height thin-wall three-way pipe, belongs to the technical field of inner high pressure forming and aims to solve the problem that the branch height of the formed three-way pipe is limited in the conventional inner high pressure forming method. The method comprises the following steps of: filling liquid media inside a pipe billet and discharging gases through a supercharger, and moving a left-side punch and a right-side punch forwards to finish pipe end seal, so that inner pressure of the pipe billet is insufficient, and the pipe billet deforms; filling liquid media on the outer side of the pipe billet through holes on a die, wherein outside hydraulic pressure is sealed by a sealing groove on the die and a sealing ring on the punch, so that the pipe billet has plastic deformation under the action of inner pressure, outer pressure, axial feeding of the left and right punches and retreating of the branch punch, and obtaining the high-branch height three-way pipe. Compared with the traditional inner high pressure forming method, the method has the advantages of high branch pipe height and high pipe surface quality, and is particularly suitable for thin-wall three-way pipe forming.

A slip ring has a slip ring track with a contact area, the contact area containing a plurality of pores or cavities. A lubricant is held within these pores and cavities and is enclosed by a top coating. When a slip ring brush is sliding over the slip ring track, it rubs off particles of the top coating, therefore opening some of the pores or cavities which release parts of the lubricant contained therein. This lubricant reduces surface friction of the slip ring brush at the slip ring track and therefore further wear, which results in an extended lifetime.
