CN206112488U - A square pipe for making winding pipe - Google Patents

Abstract

The utility model relates to a square pipe for making winding pipe is enclosed to close by roof, right side wall, diapire and left side wall and forms, and the right side wall thickness is the same with the left side wall thickness to be provided with circular arc chamfering at four edges, is top the thickness of the wall 75 of right side wall thickness 90%, is diapire thickness 40 of right side wall thickness 60%. It manages the atress that the chinese side managed according to the analysis winding, reduces roof and end the thickness of the wall to because the diapire laminating is on the parent tube, diapire thickness far is less than the ring rigidity that lateral wall thickness can not influence the winding pipe yet, thereby has practiced thrift raw and other materials. In addition, its circular arc chamfering with four edges diminishes to practice thrift the melten gel. The total materials are few, intensity is high and easy shaping.

Description

For manufacturing the square tube of winding pipe

【Technical field】

This utility model is related to the production technical field of winding pipe, and in particular to a kind of square tube for manufacturing winding pipe.

【Background technology】

In winding tube production line, first mould is extruded by square tube and extrude square tube, then square tube is spirally wound on into base tube Upper formation winding pipe.Current rhs-structure as shown in figure 3, its enclosed by roof 1, right side wall 2, diapire 3 and left side wall 4 and Into roof 1, right side wall 2, diapire 3 are identical with the wall thickness of left side wall 4, and four edges are provided with circular arc chamfering 5, circle The radius of arc chamfering 5 is more than wall thickness.As shown in figure 4, in square tube Jing after spiral winding, being carried out by melten gel 6 between adjacent square tube Bonding, so that two side walls bond to form reinforcement.In winding pipe, the thickness of the reinforcement is the main of whole winding pipe Strength support.From this, the roof 1 of square tube and the thickness of diapire 3 are then secondary, so the rhs-structure of identical wall thickness, makes Into the waste of raw material.Further, since the circular arc chamfering 5 of four edges is larger, melten gel 6 needs to be fully filled with adjacent square tube Between gap, cause the waste of melten gel 6.

【Utility model content】

To solve the above problems, first purpose of the present utility model be provide it is a kind of can save material for making Make the square tube of winding pipe.

For achieving the above object, the technical scheme that this utility model is taken is：For manufacturing the square tube of winding pipe, by pushing up Wall, right side wall, diapire and left side wall are enclosed and formed, and right side wall thickness is identical with left side wall thickness, and are set in four edges Circular arc chamfering is equipped with, the thickness of the roof is the 75-90% of right side wall thickness, and the bottom wall thickness is right side wall thickness 40-60%.

To solve the above problems, second purpose of the present utility model be provide it is a kind of can save melten gel for manufacturing The square tube of winding pipe.

For achieving the above object, the technical scheme that this utility model is taken is：The radius of the circular arc chamfering is right side wall The 10-20% of thickness.

Compared with prior art, this utility model has the advantages that：The above-mentioned square tube for manufacturing winding pipe, It reduces the thickness of roof and diapire according to the stress of square tube in analysis winding pipe, and because diapire is fitted on base tube, Bottom wall thickness does not interfere with the ring stiffness of winding pipe much smaller than sidewall thickness yet, so as to save raw material.In addition, it is by four The circular arc chamfering of edge diminishes, so as to save melten gel.Total materials are few, intensity is high and easy-formation.

【Specific embodiment】

Further detailed is made to the square tube for manufacturing winding pipe described in the utility model below by specific embodiment Thin description.

As shown in figure 1, the square tube for manufacturing winding pipe, enclosed by roof 1, right side wall 2, diapire 3 and left side wall 4 and Into the thickness of right side wall 2 is identical with the thickness of left side wall 4, and four edges are provided with circular arc chamfering 5, the thickness of the roof 1 Spend for the 75-90% of the thickness of right side wall 2, the thickness of the diapire 3 for the thickness of right side wall 2 40-60%.The circular arc chamfering 5 Radius is the 10-20% of the thickness of right side wall 2.

The above-mentioned square tube for manufacturing winding pipe, its according to analysis winding pipe in square tube stress, by roof 1 and diapire 3 thickness is reduced, and because diapire 3 is fitted on base tube, the thickness of diapire 3 does not interfere with winding pipe much smaller than sidewall thickness yet Ring stiffness, so as to save raw material.As shown in Fig. 2 it diminishes the circular arc chamfering 5 of four edges, it is molten so as to save Glue 6.Total materials are few, intensity is high and easy-formation.

The principle and its effect of the above embodiments only illustrative the invention, and the enforcement that part uses Example, not for restriction this utility model；It should be pointed out that for the person of ordinary skill of the art, without departing from this reality On the premise of being conceived with new creation, some deformations and improvement can also be made, these belong to protection model of the present utility model Enclose.
