Specific embodiment
As shown in Figure 1, we make a turntable 503 by normal bend shape feature, normal bend 10 is placed on On turntable 503.Elbow position is accurately positioned, then by rotating turntable 503, to be arranged on the circle centre position of elbow radius of curvature Hinge 505 is rotation center, how many degree no matter is rotated, elbow axis is forever with assuming that formal construction 11 axis of pipe is tangent at one On fixed point, our this point is referred to as " eternal point of contact p "." the eternal point of contact p " of different bore elbows all one with It is assumed that formally in the fixing line of construction 11 axis perpendicular of pipe, and the cutting line of elbow 10 that this line will be cut with us Track is to overlap, therefore we are referred to as " eternal tangent line q ".
As shown in Fig. 2, after the angle that rotating elbow is needed to us, at " eternal tangent line q " excessively and perpendicular to pedestal Corresponding position is marked on the outside of the elbow section of 506 planes, will be as beginning and end during cutting.Finally cut off using elbow Groove full circle all-in-one machine will need cut-out n to cut away.
The core of its principle is no matter which kind of angle normal bend 10 goes to, and cutting line must vertically assume formally to construct 11 axis of pipe allows be cut partly moving on to dash area.Elbow cutting line port is positive round forever with assuming formal construction pipe port To positive round, cut end face for elbow and ensure with follow-up formal construction pipe group providing.
Although we have accurately intercepted the elbow of the non-standard number of degrees, since elbow is substantially using shaper What hot forging made, due to being limited by technique, among elbow outside all there are one section of Free Transform section, this section of ovality compared with Greatly.And the elbow after cutting will generate certain deformation, therefore circularity can be affected to some extent due to the release of internal stress. So as to influence the quality of the assembling of the pipe fitting of subsequent handling and welding etc..Therefore it needs to carry out full circle to elbow port.It is previous each curved Head manufacturing factory full circle all by the way of stock mould and hydraulic press forging and stamping.This method equipment investment cost is big, tooling loose tool It is complicated various.It is considered that the elliptical diameter of elbow is divided into short axle and long axis, just because of elbow and pipe end face, there are short axles With the difference of long axis, certain unfitness of butt joint just will necessarily be generated in assembling.Ordinary circumstance, elliptical long axis will be greater than setting for elbow Standard size is counted, and short axle is then less than the design standard size of elbow, therefore we can be by inwardly squeezing in transverse Elbow ends are carried out full circle by pressure, the mode ejected outward in ellipse short shaft.
Concrete principle on the inside of elbow ends as shown in figure 3, push up roll wheel assembly 206, outside accordingly sets one in setting one External pressure roll wheel assembly 201, inside and outside idler wheel form a concentric roller group.It is rotated by roller group around shaft 102, mating Ring shaped heating mechanism heating after, inside and outside idler wheel manually rotates, when rotation to transverse when on the outside of roller stress inwardly squeeze, Rotation to inside roller stress during ellipse short shaft ejects outward, by multiple microfeed, rotates, is set until being fully achieved repeatedly The positive round of meter standard.
As shown in figure 4, its principle key be it is outer extruding and it is interior ejection all simultaneously in elliptical long axis or short axle both ends, idler wheel Group stress is two groups of opposite active forces of direction equal in magnitude always, i.e.,:
During long axis:F pressures 1=F presses 2 F to become 1=F changes 2,
During short axle:F tops 1=F pushes up 2 F and becomes 3=F changes 4,
It is zero that active force is cancelled out each other in mandrel.I.e.:Uniform force.Since roller group employs symmetrical structure, Being rotated in the range of 180 ° repeatedly just can reach 360 ° of full circle effect, and efficiency is greatly improved, and reach the design reason of symmetrical shaping It reads.
Equally, this method is readily applicable to the pipe end full circle of construction.
Elbow cuts away the low-angle on elbow when cutting, retain the elbow wide-angle of our needs, such as we need One 78 ° of non-standard angle elbow, we can select 90 ° of normal bend to cut away 12 °;Need one 56 ° non-standard Angle elbow, we can cut away 4 ° with 60 ° of normal bends.40 ° or 20 ° of non-standard angle elbow is also needed, we can be with It is intercepted using 45 ° or 30 ° of normal bends.
In practical applications, even normal bend, it is also possible to error occur.Therefore we need to be examined with angel measuring instrument It whether accurate tests angle of bend, if any error log error, and should be modified in assembling, to avoid cutting aftershaping elbow Angular error.If examination criteria angle of bend not enough should prescind inadequate angle value less in angle of bend is cut, such as examine It is bigger then opposite to survey angle of bend.
The port of normal bend is there is also ellipticity error, in order to which the center for ensureing end face of elbow is accurately positioned in " forever Point of contact p " on, it would be desirable to the major and minor axis of elbow is measured.
