Description

Technical Field

[0001] The invention relates to the technical field of large power transformer oil tank and structural parts processing, in particular to a tooling for a transformer lifting seat with a cylindrical axis space tilting. Background Art

[0002] The transformer riser is one of the important structural parts on the transformer. It is a part used to connect the oil tank and the porcelain sleeve. It is a support for the transformer body lead wires, bushings, and transformers. There is a type of riser with a round flange at one end and a square flange at the other end, with a cylinder in the middle, and the axis of the cylinder is inclined relative to the square flange space.

[0003] The lifting seat of this structure usually needs to be customized, and the supply is often not timely, which will affect the needs of the joint pipe assembly in the production of the oil tank, that is, the joint pipe assembly requires the use of the lifting seat and the joint pipe connected to it. In order to ensure production, it is necessary to make a tooling that simulates the lifting seat to cooperate with the production of joint pipe assembly. The lifting seat tooling of the traditional design has a pipe joint, a reinforcement ring, a cylinder, a reinforcement iron and a lower square flange, which are connected by welding. The diameter of the cylinder of this tooling is large, the rigidity of the upper end is poor, and the spatial direction of the axis of the tooling cylinder relative to the lower square flange after welding is completed is inaccurate, resulting in errors in the size and position of the pipe joint. Due to the large error of the tooling, it sometimes cannot meet the machining requirements, resulting in rework or scrapping of the tooling, and the cylinder of this tooling is a cylinder, which needs to be rolled, which is difficult to make and has a long cycle. The tooling is large in size and the material cost is high.

[0004] Therefore, in view of the fact that the cylinder diameter of the lifting seat tooling of the above-mentioned traditional design is large and the rigidity of the upper end is poor, and the cylinder of this tooling is a cylinder, which needs to be rolled, and the production is difficult and the cycle is long. The tooling is large in size and the material cost is high. The cylindrical cylinder sometimes leads to large errors in the size and position of the pipe joints, which cannot meet the machining requirements, resulting in rework or scrapping of the tooling. A lifting seat tooling for a transformer with a cylindrical axis spatial tilt can be designed. By using a structural tube instead of the cylinder and using two sets of positioning plates to achieve precise positioning of the structural tube, the accuracy of the lifting seat tooling can meet the use requirements after welding is completed, and more materials can be saved. Summary of the invention

[0005] In order to overcome the large diameter of the cylinder of the traditional design of the riser tooling and the poor rigidity of the upper end, the cylinder of this tooling is a cylinder and needs to be rolled, which is difficult to produce and has a long cycle. The tooling is large in size and has high material costs. The cylindrical cylinder sometimes causes large errors in the size and position of the pipe joints, which cannot meet the machining requirements, resulting in rework or scrapping of the tooling.

[0006] The technical solution of the present invention is: a cylindrical axis spatial tilt transformer lifting seat tooling, including a base flange, a structural tube, a first positioning plate, a second positioning plate and a pipe joint, the structural tube is arranged above the base flange, the first positioning plate and the second positioning plate are both arranged above the base flange, the first positioning plate is located on one side of the structural tube, the second positioning plate is located on the other side of the structural tube, and the pipe joint is arranged on one side of the structural tube.

[0007] Preferably, a structural tube is provided to replace the cylinder of the traditional tooling, the structural tube can be accurately positioned by providing a first positioning plate and a second positioning plate, and the production is assembled by providing a pipe joint in coordination with the connecting pipe.

[0008] Preferably, the structural tube is fixedly connected to the base flange, the structural tube is inclined relative to the base flange, and the centerline direction of the structural tube is parallel to the axis of the riser cylinder.

[0009] Preferably, the cross section of the structural tube is square, and the first positioning plate and the second positioning plate are respectively fixedly mounted on one side of two side surfaces of the structural tube.

[0013] Preferably, four groups of connection holes are provided on the surface of the pipe joint, and the four groups of connection holes are arranged in the middle of the span.

[0014] Beneficial effects of the present invention:

[0015] 1. The structural tube replaces the traditional working cylinder, which makes the production simpler and saves materials. At the same time, the base flange can be used to replace the traditional square flange, which is smaller in size. The square cross-section of the structural tube can be conveniently matched with the first positioning plate and the second positioning plate to accurately position the structural tube, so that the center line direction of the structural tube is parallel to the axis of the lifting seat cylinder.

[0023] See also Figure 1-Figure 2 In this embodiment, the structural tube 2 is fixedly connected to the base flange 1, the structural tube 2 is inclined compared to the base flange 1, and the centerline direction of the structural tube 2 is parallel to the axis of the lifting seat cylinder; by setting the structural tube 2 instead of the cylinder of the traditional tooling, the structural tube 2 is simple to manufacture and saves more materials; the cross-section of the structural tube 2 is square, and the first positioning plate 3 and the second positioning plate 4 are respectively fixedly installed on one side of the two side surfaces of the structural tube 2; the cross-section of the first positioning plate 3 is triangular, and the cross-section of the second positioning plate 4 is triangular; one side of the first positioning plate 3 overlaps one side of the second positioning plate 4, and the first positioning plate and the second positioning plate 4 are perpendicular to each other; by setting the first positioning plate 3 and the second positioning plate 4 to fit closely with the surface of the structural tube 2, the precise positioning of the structural tube 2 can be achieved.

[0024] See also Figure 3In this embodiment, the axis of the pipe joint 5 intersects perpendicularly with the center line of the structural pipe 2 and is perpendicular to a side wall plane of the structural pipe 2; by arranging the structural pipe 2 to install the pipe joint 5, the assembly of the traditional design tooling pipe joint 5 and the cylindrical arc surface can be avoided, the pipe joint 5 is convenient to position on the side wall of the structural pipe 2, and it is easy to ensure the size and position accuracy of the pipe joint 5 on the structural pipe 2; four groups of connecting holes 501 are opened on the surface of the pipe joint 5, and the four groups of connecting holes 501 are arranged in the middle of the span.

[0025] During operation, the base flange 1, the structural pipe 2, the first positioning plate 3, the second positioning plate 4 and the pipe joint 5 are welded into a whole, so as to simulate the lifting seat to cooperate with the production of the joint pipe assembly;

[0026] The structural tube 2 is used to replace the cylinder of the traditional tooling. The structural tube 2 is simple to produce, has a short construction period, and saves more materials. The structural tube 2 is small in size, so that the square flange of the traditional tooling bottom plate can be replaced by the rectangular base flange 1, and the volume can be reduced to one third of the traditional square flange, saving more space and materials.

[0027] By using the first positioning plate 3 and the second positioning plate 4 to fit closely with the surface of the structural tube 2, the structural tube 2 can be accurately positioned, and the center line direction of the structural tube 2 can be ensured to be parallel to the axis of the cylinder of the lifting seat, which is more convenient for accurate positioning than the cylinder of the traditional tooling;
