PVC base pipe is after extruder squeezes out by adding after base pipe is transmitted heating equipment by level-one dragger by sizing cooling Hot equipment is heated, and is completely wrapped up under elastomeric state by second level traction machine travel after base pipe is heated and (being expanded by dilatation mold Socket) biaxial tension to PVC pipe is completed, it is formed under the rapid cooling of cooling equipment after the tubing after stretching.? In the prior art, the tube wall of expander cylinder is an integral structure, in this way when carrying out different size caliber expansion operations to mother tube, It just needs to replace expander cylinder.In order to solve the problems, such as that expander cylinder replacement operation is cumbersome, the present invention provides a kind of adjustable Formula elasticity tubing pipe expander, is mountable on PVC-O pipe production line, for realizing the expander of tubing.
The present invention carries out structure optimization to expander cylinder: firstly, expander cylinder is designed to split type structure, i.e., by former expander cylinder At least two cutting units, i.e. expansion wall 1 in the present invention are split into, the structure that each expands wall 1 is identical.
In the present invention, which includes expander cylinder, needs to carry out the mother tube of expander It is initially heated in production line, then passes through on the outside of expander cylinder again, the diameter that the diameter of expander cylinder is greater than mother tube (is equal to Pipe diameter size after expander), such mother tube realizes that caliber is expanded under the action of expander cylinder.
In the specific embodiment of the present invention, expand there are four the settings of wall 1, when such expander cylinder diameter becomes larger, Expanding wall 1 to expand outward, the exterior contour of expander cylinder and round dimensional discrepancy are smaller, meanwhile, four expansion walls 1 are right two-by-two Claim, additionally it is possible to improve internal component stress balance of the present invention, simultaneously, additionally it is possible to guarantee that structure of the invention is more simplified.
When carrying out caliber expansion, the outside of medial surface and expander cylinder is in close contact mother tube, in order to avoid expander cylinder The appearance of scuffing problem is caused to the medial surface of mother tube, the lateral surface for expanding wall 1 is designed as flat and smooth song by the present invention Face structure, also, the outer rim for expanding wall 1 is designed to by chamfering outer rim by technique for grinding.
It is provided with extension component in the inside of expander cylinder, extension component is set in expander cylinder and for expansion wall 1 Movement is controlled, and extension component can be carried out while be controlled to the multiple expansion walls 1 for constituting expander cylinder, so that whole Expand wall 1 equidistantly to be moved.
