Description

Butt joint for hydraulic composite pipe forming machine Technical Field The invention relates to the technical field of composite pipe forming for multi-layer pipe walls, in particular to a butt joint of a hydraulic composite pipe forming machine. Background Along with the development of society, the science and technology are advanced, the requirements of people on life are also higher, and the requirements on pipe fittings in some special fields are also high. For example, in some occasions, a composite pipe with a multi-layer pipe wall is needed to replace a common pipe with a single-layer pipe wall, for example, in the actual working condition occasions, a pure copper pipe is needed, but the pure copper is softer and has higher cost, and then a thinner pure copper pipe is needed to be attached inside a steel pipe which is firm and has relatively lower cost so as to achieve the same technical effect. However, in general, the shape of the pipe is thin and long, so that the conventional method for manufacturing the conforming pipe cannot manufacture the thin and long conforming pipe, and even if it can be realized, it is difficult to ensure that each layer of pipe wall has a relatively uniform wall thickness along the length direction of the whole pipe and is firmly adhered to each other, so that in order to solve such a technical problem, a person skilled in the art needs to develop a hydraulic composite pipe forming machine butt joint for a composite pipe hydraulic press capable of forming through all-line constant pressure.
