Description
Technical field
The utility model relates to a kind of vacuum sizing device.
Background technology
Can be divided into internal diameter sizing method and external diameter sizing method to the sizing method of tubing, wherein, external diameter sizing method is divided into again interior compression set shot and vacuum sizing method, traditional vacuum sizing method, and the extrudate of head section is easily bonded on sizing jacket wall, affects the sizing of tubing.
Utility model content
For the problems referred to above, the utility model provides a kind of vacuum sizing device, makes the inwall close contact of outer pipe wall and vacuum sizing sleeve, avoids the extrudate of head section to be bonded on sizing jacket wall simultaneously, improves tubing fixed effect.
For realizing above-mentioned technical purpose, reach above-mentioned technique effect, the utility model is achieved through the following technical solutions:
A kind of vacuum sizing device, comprise head plug, the arranged outside of described head plug has a mouthful mould, the annulus for being squeezed into tubulose is formed between described head plug and mouth mould, be disposed with vacuum sizing sleeve and bosh outside tubing after extrusion, it is characterized in that, between described vacuum sizing sleeve and tubing, be provided with cooling section and vacuum zone, described cooling section is arranged near head plug side, described vacuum zone be provided be connected with vavuum pump vacuumize hole.
Preferably, described cooling section is provided with inlet opening and osculum.
Preferably, be provided with several cooling sections and vacuum zone between described vacuum sizing sleeve and tubing, and cooling section arranges at equal intervals, between cooling section, be provided with vacuum zone.
By vacuumizing in vacuum sizing sleeve, utilize vacuum hole that tubing is held, make the inwall close contact of outer pipe wall and vacuum sizing sleeve, to guarantee that tubing is shaped, and, due to tubing arranged outside cooling section after extrusion, the extrudate of head section effectively can be avoided to be bonded on sizing jacket wall, improve tubing fixed effect.
The beneficial effects of the utility model are: sizing is effective, and pipe outer surface is smooth, and be easy to operation, tubing internal stress is little, and waste material is less.Make the inwall close contact of outer pipe wall and vacuum sizing sleeve, avoid the extrudate of head section to be bonded on sizing jacket wall simultaneously, improve tubing fixed effect.
