Problems solved by technology

[0009] Compared with the liquid medium extrusion bulging method, although the plastic medium separation punch extrusion bulging method is more complicated, it avoids the expensive hydraulic pressure boosting system, so it has less equipment investment, high productivity and good forming effect. Good advantages, but it also has a low service life of the punch, a complex mold structure, and cannot be applied to occasions where the size of the tube blank is too small

Abstract

The invention discloses a locking rigid-plastic compound bulging forming apparatus for hydraulic controlled type three-way pipes. The locking rigid-plastic compound bulging forming apparatus comprises an upper half die and a lower half die; a forming cavity is formed between the upper half die and the lower half die; bulging extrusion punches are mounted at the two ends of the forming cavity, respectively; a branch pipe forming cavity is formed in the lower half die and a balance punch is mounted in the branch pipe forming cavity; a rigid bulging inner die is arranged between the two bulging extrusion punches; the rigid bulging inner die comprises push rods located at both ends, respectively, and a forming inner module matched with the branch pipe forming cavity and used for driving a pipe billet to bulge and deform is arranged between the two push rods; the forming inner module is connected with the two push rods through a connecting rod mechanism; axes of the push rods are in sliding fit with the forming cavity, respectively, and the push rods are mounted in the corresponding bulging extrusion punches; a bulging liquid inlet and a bulging liquid outlet are formed in the bulging extrusion punches, and a quick demounting connecting structure is arranged on one push rod; compound hydraulic cylinders are arranged at the two ends of the forming cavity, respectively.

Description

technical field [0001] The invention belongs to the technical field of non-cutting processing of pipe materials, and in particular relates to a liquid-controlled three-way pipe lock-type rigid-plastic composite bulge forming equipment. Background technique [0002] There are many types of pipe bulging, mainly divided into two types: rigid bulging and soft mold bulging. Rigid punch bulging is only suitable for bulging of axisymmetric bulging parts that do not require high shape and dimensional accuracy. When liquid, gas or elastomer is used as the pressure transmission medium for bulging, it is commonly called soft mold bulging. The liquid can be oil, emulsion or water, and the elastomer usually adopts polyurethane rubber or natural rubber. Due to its unique characteristics of being easy to be solid or liquid, and recyclable and reusable, paraffin wax is also used as a bulging pressure transmission medium, and has achieved good technical results in production. Therefore, a...
