The utility model provides a thin-wall short-cone cylinder welding control tool, see fig. 2 and 3, comprising a cylinder body, wherein the cylinder body is formed by splicing a first cone 1, a second cone 2 and a third cone 3 along the circumferential direction, an upper positioning plate 4 is arranged on the upper end surface formed by splicing the first cone 1, the second cone 2 and the third cone 3, and a lower positioning plate 5 is arranged on the lower end surface; the first cone 1 and the second cone 2 are matched in a locating mode through dovetail grooves, and the third cone 3 is matched with the first cone 1 and the second cone 2 through inclined planes respectively.
The utility model discloses a barrel that forms is spliced along circumference by first cone 1, second cone 2 and third cone 3, and the upper and lower terminal surface of barrel is provided with locating plate 4 and locating plate 5 down respectively. And, in order to guarantee that it is difficult for misplacing and easy dismantlement at frock concatenation in-process, through forked tail location fit between first cone 1 and the second cone 2, all have assorted inclined plane structure on the connecting portion that third cone 3 links to each other with first cone 1, second cone 2. First, the first cone 1 and the second cone 2 are spliced, then the third cone 3 is pushed in from outside to inside along the axial direction of the barrel, and then an upper positioning plate 4 and a lower positioning plate 5 are fixed on the upper end surface and the lower end surface of the barrel formed by splicing so as to keep the strength of the tool. After the thin-wall sheet metal part is rolled and formed, the workpiece 8 is sleeved outside the cylinder body, and then operations such as welding, shape correction and the like are carried out; after the operation is completed, the upper positioning plate 4 and the lower positioning plate 5 are removed, then the third cone 3 is pushed out between the first cone 1 and the second cone 2, and then the workpiece 8 is easily removed. The utility model provides a work piece 8 non-deformable in welding process can be guaranteed to the frock, and takes off and difficult production damage from the frock easily to reach the mesh of control deformation. Wherein, can guarantee through forked tail location fit between first cone 1 and the second cone 2 that its both splice the difficult dislocation of partial barrel that forms.
In the actual production process, some workpieces are tapered, so the cylinder body and the workpiece 8 have the same taper.
Specifically, referring to fig. 1, both end surfaces of the third cone 3 have an inclined surface structure formed by diffusing and inclining from outside to inside; the angle between the inclined plane and the vertical plane is 6 deg.. Therefore, the third cone 3 can be easily pushed into the spliced first cone 1 and the second cone 2, and the outer side surface of the barrel formed by splicing conveniently shrinks inwards. After welding or correction, the upper positioning plate 4 and the lower positioning plate 5 can be detached firstly, then the third cone 3 is pushed out from between the first cone 1 and the second cone 2, and then the thin-wall workpiece 8 sleeved outside the tool is easily taken out and the workpiece 8 is not easy to damage.
