Description
Technical field
The present invention relates to supporting tool during a kind of two thin cylinder butt welding, the weldering of joining particularly during a kind of two thin cylinder butt welding is enclosed.
Background technology
For the welding of two thin cylinder butt girth welding seams, when adopting the welding of circumferential weld welding machine special, must arrange below weld seam and join weldering circle, be beneficial to appearance of weld, can avoid because circumferential weld welding machine special can produce larger fusion penetration relative to during handwork, thus cause occurring in welding procedure burning or the defect such as superfusion.But when adopting conventional mode of joining weldering circle with material to weld, joining weldering circle after welding can fuse into one with product shell, join and weld circle and take off and substantially cannot realize.In addition, weldquality be guaranteed, certain speed of welding will be ensured, by the impact that workpiece welding line joint actual size and other welding parameter fluctuate, after weldering circle is joined in use, the groove of joining on weldering circle cannot be full of by welding liquation, and weld seam encloses bottom portion of groove and there is certain gap with joining to weld.After welding completes, join weldering circle molten in order to one with cylindrical shell, when utilizing x-ray detection butt welded seam quality to detect, weld seam center bottom reflects a superfine black line sometimes on X-ray, doubtful lack of penetration defect, causes occurring being difficult to pass judgment on to the testing result of X-ray.
Summary of the invention
The invention provides a kind of thin cylinder and join weldering circle to welding combined, solve existing two thin cylinder butt joint ring postweldings and join the technical problem of welding circle and cannot take off and girth joint X-ray check result is difficult to judgement.
The present invention solves above technical problem by the following technical programs:

Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is described in detail:
A kind of thin cylinder joins weldering circle to welding combined, comprise left front half weldering circle 1, left back half weldering circle 2, bottom right half weldering circle 3 and upper right half weldering circle 4, left deep-slotted chip breaker 5 is provided with at the exterior dome surface right-hand member of left front half weldering circle 1 and the exterior dome surface right-hand member of left back half weldering circle 2, in bottom right, the exterior dome surface left end of half weldering circle 3 and the exterior dome surface left end of upper right half weldering circle 4 are provided with right deep-slotted chip breaker 6, left deep-slotted chip breaker 5 is butted into right deep-slotted chip breaker 6 and abdicates annular groove 21, left front lower screwed hole 9 and left front upper screwed hole 10 is respectively arranged with at the two ends of left front half weldering circle 1, left back lower screwed hole 8 and left back upper screwed hole 7 is respectively arranged with at the two ends of left back half weldering circle 2, in bottom right, the two ends of half weldering circle 3 are respectively arranged with preceding thread hole, bottom right 13 and rear thread hole, bottom right 14, upper right preceding thread hole 12 and upper right rear thread hole 11 is respectively arranged with at the two ends of upper right half weldering circle 4, left back upper screwed hole 7 is screwed together by screw with upper right rear thread hole 11, left back lower screwed hole 8 is screwed together by screw with rear thread hole, bottom right 14, left front upper screwed hole 10 is screwed together by screw with upper right preceding thread hole 12, left front lower screwed hole 9 is screwed together by screw with preceding thread hole, bottom right 13, left front half weldering circle 1, left back half weldering circle 2, bottom right half weldering circle 3 and upper right half weldering circle 4 are connected by screw rear composition torus, left deep-slotted chip breaker 5 docks with right deep-slotted chip breaker 6 and forms that annular welds seam is inwardly protruded abdicates annular groove 21.
Gap 16 is provided with between the upper end and left back upper end of partly welding circle 2 of left front half weldering circle 1, lower gap 15 is provided with between the lower end and left back lower end of partly welding circle 2 of left front half weldering circle 1, the rear end of bottom right half weldering circle and and upper right half weld circle 4 rear end between be provided with after gap 17, the front end of bottom right half weldering circle and and upper right half weld circle 4 front end between be provided with before gap 18, the boss 19 that cross section is right-angled trapezium is provided with on the right flank of left front half weldering circle 1 and on the right flank of left back half weldering circle 2, the left surface of bottom right half weldering circle 3 and the left surface of upper right half weldering circle 4 are provided with the groove 20 that cross section is right-angled trapezium.
Knockdown joining of the present invention welds circle, is assemblied in left thin cylinder 22 and butt weld 24 place of right thin cylinder 23, dismantles, so both ensure that the quality of weld seam, can not increase extra weight again for product at postwelding to it before weldering.This joins weldering circle for fabricated structure, has the function that routine joins weldering circle, can install, dismounting from handle hole seat after having welded before Product jointing from product body end surface after assembling, and mounting or dismounting are dexterous convenient.The stainless steel water cutting processing of four and half weldering circle employings 20 millimeters forms, after machining, be combined into a full circle, the abutment joint of left side two halves weldering circle is arranged on top and bottom, the abutment joint of right side two halves weldering circle is arranged on front-end and back-end, just four and half weldering circles can be assembled into an overall annulus by screw, weldering circle in left side half welds to enclose with half of right side and adopts boss and groove fit, at the boss place near inner circle, inclined plane is set, namely cross section is at right angles trapezoidal boss 19, at the groove near inner circle, inclined plane is set, namely cross section is at right angles trapezoidal groove 20, after the screw left and right sides being fixed two halves weldering circle takes off, due to the existence in gap between two halves weldering circle, half weldering circle can slide along the inclined plane arranged between boss and groove, facilitate half dismounting of weldering circle in handle hole seat.The present invention can utilize girth welding welding machine special to complete welding to thin-wall circular tube kind part butt girth welding seam product, obtain high-quality weld seam, can dismantle joining weldering circle at postwelding again, the detection simultaneously also facilitating seam inspection reduces the erroneous judgement of butt welded seam quality.
