Preferably, in the device of above-mentioned raising PE pipe inner circle flatness, described expansion orthopaedic component is polytetrafluoroethylene (PTFE) expansion orthopaedic component.
As can be seen from technique scheme, a kind of device improving PE pipe inner circle flatness provided by the utility model, because the front end seamless link at shaping mould plug has expansion orthopaedic component, the maximum gauge of described expansion orthopaedic component is larger than the diameter of described shaping mould plug, and the difference of the two is preset value, the setting of described preset value can make the inner circle flatness of PE pipe reach acceptance value, therefore, it is possible to the inner circle nao-and micro relief of defective work is changed in acceptability limit, thus make it become qualified products, reduce production cost.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only embodiment of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to the accompanying drawing provided.
The schematic diagram of the device of the first raising PE pipe inner circle flatness that Fig. 1 provides for the embodiment of the present application.
Detailed description of the invention
Core concept of the present utility model is to provide a kind of device improving PE pipe inner circle flatness, the inner circle nao-and micro relief of defective work can be changed in acceptability limit, thus make it become qualified products, reduce production cost.
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
The embodiment of the present application provide the first improve the device of PE pipe inner circle flatness as shown in Figure 1, Fig. 1 provide for the embodiment of the present application the first improve the schematic diagram of the device of PE pipe inner circle flatness.In the apparatus, expansion orthopaedic component 2 is had in the front end seamless link of shaping mould plug 1, the maximum gauge of described expansion orthopaedic component 2 is larger than the diameter of described shaping mould plug 1, and the difference of the two is preset value, and the setting of described preset value can make the inner circle flatness of PE pipe reach acceptance value.
Concrete, in the course of the work, when PE pipe inner circle leaves shaping mould plug 1, due to a cylindrical preset value larger than plug of the expansion orthopaedic component 2 of increase, be conducive to inner circle to expand from film, after walking certain distance, complete being fitted in of inner circle of PE pipe is expanded on orthopaedic component 2 vertically, at this moment the diameter expanding orthopaedic component 2 is identical with the diameter of shaping mould plug 1, after the inner circle of PE pipe continues to prolong axial traveling one segment distance, the inner circle of PE pipe is progressively close to expansion orthopaedic component 2, the inner circle of PE pipe walk on vertically expand after a segment distance complete, now the interior circular diameter of PE pipe will by of short duration expansion preset value, then original interior circular diameter can be automatically restored to, obtain finished product, thus improve the brightness of inner circle, reduce the nao-and micro relief of inner circle.
As can be seen from technique scheme, a kind of device improving PE pipe inner circle flatness that the embodiment of the present application provides, because the front end seamless link at shaping mould plug has expansion orthopaedic component, the maximum gauge of described expansion orthopaedic component is larger than the diameter of described shaping mould plug, and the difference of the two is preset value, the setting of described preset value can make the inner circle flatness of PE pipe reach acceptance value, therefore, it is possible to the inner circle nao-and micro relief of defective work is changed in acceptability limit, thus make it become qualified products, reduce production cost.
The second that the embodiment of the present application provides improves the device of PE pipe inner circle flatness, except have with above-mentioned the first improve except the identical technical characteristic of the device of PE pipe inner circle flatness, also comprise following technical characteristic: the shape of described expansion orthopaedic component is round table-like, be arranged to the round table-like feature that just can make it have diameter and slowly increase, be unlikely to block in the course of the work, and in this second device, the scope of described preset value can be chosen as 0.5mm to 0.8mm, the brightness of inner circle can either be improved like this, be unlikely to again to cause potential expendable distortion by excessive for the expansion of the inner circle of PE pipe.
As a kind of preferred version, described expansion orthopaedic component can also have the first shaping portion and the second shaping portion, the diameter in described first shaping portion is equal with the external diameter of described PE pipe, the diameter in described second shaping portion is greater than the external diameter of described PE pipe, so just initially the inner circle of PE pipe is not being expanded, but there is a buffering, then just expand, the damage to PE pipe can be reduced so further.Optionally, the axial length in described first shaping portion is 5mm, and the axial length in described second shaping portion is 5mm, and such length can strengthen the effect of above-mentioned buffering further.
In addition, described expansion orthopaedic component can be polytetrafluoroethylene (PTFE) expansion orthopaedic component, because the temperature tolerance of polytetrafluoroethylene (PTFE) is better, can bear the high temperature of less than 800 degree, and the hardness number of polytetrafluoroethylene (PTFE) is lower, thus good PE pipe inner circle quality can be obtained.
Utilize said apparatus, when production cost does not change, the waste product in production process can be digested, the nao-and micro relief of product inner circle is reduced to from 2.0 microns to 3.2 microns and is no more than 0.8 micron, improve the presentation quality of product.
To the above-mentioned explanation of the disclosed embodiments, professional and technical personnel in the field are realized or uses the utility model.To be apparent for those skilled in the art to the multiple amendment of these embodiments, General Principle as defined herein when not departing from spirit or scope of the present utility model, can realize in other embodiments.Therefore, the utility model can not be restricted to these embodiments shown in this article, but will meet the widest scope consistent with principle disclosed herein and features of novelty.
