Technical field
The present invention relates to mechanical equipment technical field, especially a kind of trail-type biaxially oriented tube of passive roller continuously at
Type equipment.
Background technology
Currently, the stretching orientation process of high molecular material is temperature of the material between glass transition temperature and melting temperature
Under, polymer chain structure structure is made by the control (temperature, stress etc.) of certain flow field control and processing and forming condition and is divided
There is enhancing trend in cloth, and preferentially arranges along Impact direction.Molecule is from disorderly arranged to the process of ordered arrangement.Macromolecular chain by
In realizing ordered arrangement, material is anisotropy by isotropic transition, i.e., material along molecular orientation direction intensity substantially
Increase.Using the orientation feature of high molecular material, biaxial tension is carried out to tubing, can improve simultaneously tubing circumferential intensity and
Axial strength realizes the raising of tubing comprehensive performance.
At this stage, the manufacturing technology of biaxially oriented tube is divided into two major classes：Two step processing methods and a step processing method.Two steps are processed
Method is commonly called as offline process or batch process, refers to the production of shell and dilates the independent separated progress of pipe step, shell exists
It squeezes out and after cooling and shaping, is admitted to and dilates process.It is heated to suitable expander temperature in expansion processes pipe indusium, reuses one
Fixed method expander, cooling, sizing.The advantages of two-step method, is that equipment is simple, simple for process, and operating process separates only in two places
Vertical to carry out, the degree of orientation is easy to control and can obtain the big degree of orientation, and material is applied widely.Disadvantage is that labour consumes
Greatly, overall efficiency is relatively low, and since it is desired that Repeat-heating, so energy consumption is higher.Domestic enterprise is due to fund and technical side at present
The restriction in face still uses two one-step forming methods, causes high energy consumption, production cost height, inefficiency.One-step method refers to
Pipe after the extrusion, controls technological parameter, and pipe is synchronous after squeezing out to carry out expander technique.Compared to two-step method, its advantage is that
Producing line is compact-sized, energy saving and high degree of automation, and disadvantage is that equipment and complex process, and product scope has a fixed limit
System.
Technical barrier and development bottleneck existing for pipe method and apparatus are squeezed for current biaxial tension, development is a kind of novel
The trail-type biaxially oriented tube continuous shaping method of passive roller and equipment, to pushing the advanced manufacture of China's bi-directional synchronization stretching tube
It is of great significance.
