Abstract
The utility model provides an HDPE hollow wall winding pipe outer surface heat-treating device which adopts a heating device, and the heating surface of the heating device coincides with the outer surface of a winding pipe. The utility model carries out heating treatment to the outer surface of the winding pipe after the winding pipe is molded so as to release the stress of the outer surface and the inner part of the winding pipe, thereby stabilizing the quality of the winding pipe. Mechanical properties of the winding pipe are effectively enhanced and the surface stress is eliminated through reasonable control of an adjustment device to the heating temperature and the heating time of the outer surface of the winding pipe.
Description
Technical field
The utility model relates to the Equipment for Heating Processing of HDPE hollow wall winding tube Production Flow Chart, particularly relates to a kind of outer surface heat treatment facility.
Background technology
HDPE winding arrangement tubing purposes is very extensive, and its main advantage is to produce the heavy caliber product, can use bantam to produce bore greater than 1 meter tubing.But,, be welded through bending owing to be by behind the small size square tube cooling forming in the production process; Square tube is forced to bend to circle and welds, and the welding fabrication product surface stretched by bending and can produce the internal stress of shrinking this moment, and this stress can not get discharging and is retained in product inside all the time; Product is subjected to the influence of envrionment temperature in depositing process, expansion occurs than big-difference with the coefficient that shrinks, and when quality of materials is unstable, adds the product internal stress, must cause very big destructiveness.Thereby influence the stability of quality product.
In order to improve HDPE winding tube quality, before welding is twined in many at present uses thermal pretreatment is carried out at square tube R angle, this method can guarantee weldquality, but can not eliminate internal stress, quality product is difficult to improve.Can only enhance product performance by improving raw materials quality.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of elimination HDPE hollow wall winding tube mechanical stress is provided, and improves the product physicals, solves the outer surface heat treatment facility of product outer wall cracking phenomena.
In order to realize the foregoing invention purpose, the technical scheme of employing is as follows:
A kind of HDPE hollow wall winding tube outer surface heat treatment facility adopts an electro-heat equipment, and the heating face of described electro-heat equipment coincide with the outside surface of winding tube.
Described electro-heat equipment adopts square or circular process furnace, and this process furnace is provided with the endoporus that coincide with the winding tube outside surface, and described heating face is arranged on the endoporus.
Described electro-heat equipment also is provided with the heating temp of control heating face and the setting device of fever time.
The utility model carries out heat treated to the winding tube outside surface after the winding tube moulding, winding tube outside surface and internal stress are released, thus the quality of stable winding pipe., effectively improve the winding tube mechanical property and eliminate surface stress rationally controlling the Heating temperature and the heat-up time of winding tube outside surface by setting device.
Hot face of the present utility model is towards the winding tube outer wall surface, and promptly exterior arc surface so the hot face of process furnace should be interior circular arc, heats to inner headed face.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing the utility model is described further.
Structural representation of the present utility model is square process furnace 1 as shown in Figure 1, and process furnace 1 is provided with the endoporus that coincide with winding tube 2 outside surfaces, and described heating face is arranged on the endoporus.Winding tube 2 after Wrapping formed is inserted in the endoporus, heating face heating by endoporus is heated winding tube 2 outside surfaces,, effectively improve winding tube 2 mechanical properties and eliminate surface stress rationally controlling the Heating temperature and the heat-up time of winding tube 2 outside surfaces by setting device.
Claims (3)
1, a kind of HDPE hollow wall winding tube outer surface heat treatment facility is characterized in that adopting an electro-heat equipment, and the heating face of described electro-heat equipment coincide with the outside surface of winding tube.
