Description
Technical field
The present invention relates to sebific duct moulding process, particularly relate to a kind of bending tube connector moulding process.
Background technology
Sebific duct forming method, by whether adopting tube core, can be divided into and have core method (comprising again soft core method and hard core method), called non-sleeve method.Hard core method adopts metal or rigid plastics plug to carry out shaping, be about to by extrude the pipe produced be enclosed within plug carries out shaping.The feature of hard core method is that shaping sebific duct internal diameter size is accurate, smooth, and the adherence between glue-line and enhancement layer is good.But can shaping sebific duct length shorter, and have difficulties when making bend pipe, plug is more difficult to be extracted in sebific duct.
In particular cases need arm to be inserted in supervisor's connection at some, in the connection difficult forming near sebific duct crooked position, because plug cannot be extracted, thus govern the application of many logical connecting lines.Traditional approach adopts pipeline connecting parts to be withheld by collar by many sebific ducts or the fixed form such as clip clamping connects, but the how logical connection rubber tube of this kind of mode easily occurs sealing problem at line connection, easily in use for some time to leak at line connection.
Summary of the invention
The technical assignment of technical problem to be solved by this invention and proposition improves prior art, a kind of bending tube connector moulding process is provided, the sebific duct moulding process solved in current technology is difficult to make bending tube connector, the problem that plug is not easily extracted in the sebific duct of brake forming.
For solving above technical problem, technical scheme of the present invention is:
A kind of bending tube connector moulding process, comprises the following steps:
