Detailed Description

First, it should be understood by those skilled in the art that the embodiments described herein are merely for explaining the technical principles of the present invention, and are not intended to limit the scope of the present invention.

Referring to fig. 1 and 2, the utility model provides a return bend welding position ware for to wait to weld the pipe and wait to weld straight tube 51 welding together, it includes a diaphragm 11, two risers 12, a setting element 2, two clamping pieces and a bolt 4.

The two vertical plates 12 are symmetrically arranged in parallel, and the distance between the two vertical plates 12 is consistent with the outer diameter of the circular pipe to be welded. The transverse plate 11 is located between the two vertical plates 12 and is connected with the two vertical plates 12 in a welding mode, and the transverse plate 11 is perpendicular to the two vertical plates 12. Only part of the plate body of the transverse plate 11 extends into the space between the two vertical plates 12, and the length of the transverse plate 11 extending into the space between the two vertical plates 12 is smaller than that of the vertical plates 12, so that a transverse plate 11 area and a transverse plate 11-free area are formed between the two vertical plates 12. Referring to fig. 3 and 4, in the preparation process of welding, it is necessary to place the straight pipe 51 to be welded in the area with the transverse plate 11, support the straight pipe 51 to be welded by the transverse plate 11, and place the bent pipe 52 to be welded in the area without the transverse plate 11.

The positioning piece 2 comprises a rotating plate 21, the rotating plate 21 is positioned in the area without the transverse plate 11 between the two vertical plates 12, and the rotating plate 21 and the vertical plates 12 are in a vertical state. The rotating shafts 23 are respectively welded at two ends of the rotating plate 21 close to the two vertical plates 12, and the rotating shafts 23 are perpendicular to the vertical plates 12. The vertical plate 12 is provided with a first through hole 121 adapted to the rotating shaft 23, and the rotating shaft 23 penetrates through the first through hole 121, so that the rotating plate 21 can rotate around the rotating shaft 23.

Plate-shaped swinging pieces are respectively welded at two opposite ends of the two rotating shafts 23, and the swinging pieces and the rotating plates 21 are positioned on the same plane. The surfaces of two opposite sides of the two vertical plates 12 are respectively welded with a baffle 122, and the baffles 122 are vertical to the vertical plates 12. When the rotating plate 21 rotates to the vertical state, the shutter 122 abuts against the swinging member, restricting the rotation of the rotating plate 21. In addition, the length of the baffle 122 is smaller than that of the swinging member, so that the positioning member 2 can be conveniently held by hand when being rotated.

A cylindrical bulge 22 is integrally formed on the surface of the rotating plate 21, the projecting direction of the bulge 22 is vertical to the rotating plate 21, and the center of the bulge 22 is in the symmetrical plane of the two vertical plates 12. The projection 22 protrudes less than 0.5mm in length, and the diameter of the projection 22 coincides with the inner diameter of the circular tube with welding. Referring to fig. 5, when the rotating plate 21 rotates to the vertical state, the protruding portion 22 faces to the side away from the area with the transverse plate 11, and the protruding portion 22 is used for extending into the circular tube to be welded, and at this time, the protruding portion 22 coincides with the axis of the straight tube 51 to be welded placed on the transverse plate 11, so that the protruding portion 22 can accurately position the circular tube to be welded. Because the protruding length of the protruding portion 22 is small, the positioning member 2 can rotate smoothly after the positioning member 2 positions the round pipe to be welded.

Two clamping pieces are arranged on two opposite sides of the two vertical plates 12 and are symmetrically arranged. The clamping piece is L-shaped. The vertical sections of the two clamping pieces are connected with the vertical plate 12 in a welding way, and the horizontal sections of the two clamping pieces extend out in opposite directions. Threaded holes 32 and through holes are respectively formed in the horizontal sections of the two clamping pieces, and the through holes are coaxial with the threaded holes 32 and have the same aperture. The bolt 4 is inserted through the through hole and screwed into the threaded hole 32. The bolt 4 is embodied as a shoe-shaped bolt 4. The two clamping pieces can move towards or away from each other by screwing the bolt 4, so that the two vertical plates 12 are driven to deform in a way of moving towards or away from each other, and the circular tube to be welded between the two vertical plates 12 can be clamped or loosened.

The utility model discloses an implementation process does: rotating the positioning part 2 until the rotating plate 21 is in a vertical state, wherein the baffle plate 122 abuts against the swinging part, then placing the circular pipe to be welded between the two vertical plates 12 and enabling the protruding part 22 to extend into the circular pipe to be welded, and accurately positioning the circular pipe to be welded; then screwing the bolts 4 to deform the two vertical plates 12 and clamp the circular tube to be welded; then, rotating the positioning piece 2 to separate the protruding part 22 from the circular tube to be welded, placing the straight tube 51 to be welded on the transverse plate 11, enabling the straight tube 51 to be welded to be opposite to the circular tube to be welded, and enabling a gap between the straight tube 51 to be welded and the circular tube to be welded to be located in a region without the transverse plate 11; then, referring to fig. 4, in the area without the barrier of the transverse plate 11, a spot welding is performed on the gap between the circular tube to be welded and the straight tube 51 to be welded, and after welding, the circular tube to be welded and the straight tube 51 to be welded are relatively fixed, and accurate butt joint is ensured; then the round pipe to be welded and the straight pipe 51 to be welded are removed from between the two risers 12, and the rest of the seam welding work can be directly completed.
