Technical Field

[0001] The utility model relates to a revolving body casting correction platform, in particular to an auxiliary device for correcting the elliptical deformation of the revolving body casting, and belongs to the technical field of casting. Background Art

[0002] Rotating body structure castings are common in the casting field, such as the wheel belt on the rotary kiln equipment, the hopper on the blast furnace equipment, the intermediate cylinder on the tire vulcanizer equipment, etc. They are prone to deformation during the production process for the following reasons: ① When the casting is solidified in the cavity after pouring, the temperature field of each part is different, and the resistance of the inner core during shrinkage is uneven, so elliptical deformation will occur; ② During the heat treatment process of the casting, since the fire mouth is on both sides of the casting, the outer part is cooled first when it is cooled out of the kiln, and the cross direction is cooled later, so a second elliptical deformation will occur.

[0003] In the hot processing industry, casting deformation is inevitable. The commonly used correction method is to heat the deformed part and expand the deformed part outward with a jack. In this process, the staff is required to heat the deformed part accurately. However, most of the rotating castings are cylindrical, and the castings cannot be firmly fixed on the workbench. When heated, the castings are prone to rolling, resulting in inaccurate heating position, which may cause deformation of other parts of the casting or safety hazards such as the casting rolling to the ground.

[0019] For example, see Figure 1-Figure 2 An auxiliary device for correcting the elliptical deformation of a rotating body casting comprises a cylindrical casting A, a workbench 1, a leg 2 and an arc-shaped pressing plate 13. The leg 2 is arranged at the bottom of the workbench 1, an arc-shaped groove 3 is dug in the middle of the workbench 1, a positioning ring 4 is arranged on the outer side of the arc-shaped groove 3, the cylindrical casting A is placed in the arc-shaped groove 3, clamping plates 14 are arranged on both sides of the port of the cylindrical casting A, the clamping plates 14 are fixedly connected to the positioning ring 4 through a pull rope 15, and brackets 5 are arranged on both sides of the workbench 1, and a heating gun clamping assembly is slidably connected to the bracket 5.

The splint 14 is inserted in the middle and lower part of the port A of the cylindrical casting and fixed by the tightening bolt. One end of the pull rope 15 is connected to the lifting ring, and the other end of the pull rope 15 is fixedly connected to the positioning ring 4.

[0021] A support block 11 is arranged in the middle of the right end surface of the workbench 1 , a second support rod 12 is inserted into the support block 11 and fixed by bolts, and an arc-shaped pressing plate 13 is arranged at the left end of the top of the second support rod 12 .

[0022] The heating gun clamping assembly consists of a displacement sleeve 6, an insert sleeve 7 and a first support rod 8. The displacement sleeve 6 is slidably connected to the bracket 5, and a tightening bolt is arranged on the outside of the displacement sleeve 6. An insert sleeve 7 is vertically arranged on the top of the displacement sleeve 6, the first support rod 8 is inserted in the insert sleeve 7, and a tightening bolt is arranged on the outside of the insert sleeve 7.

[0023] A lower arc plate 9 is fixedly connected to the top of the first support rod, and an upper pressing plate 10 is arranged above the lower arc plate 9. The lower arc plate 9 and the upper pressing plate 10 are fixedly connected together by bolts.

[0024] The positioning ring 4 is located at the edge of the workbench 1 .

[0025] In the above description, clamping plates are respectively arranged on both sides of the two ends of the cylindrical casting, and the clamping plates are located below the middle position of the cylindrical casting. In actual operation, the clamping plates are far away from the correction position.

[0026] In the above description, the tightening bolts on the inner side of the clamping plate securely connect the clamping plate to the end of the cylindrical casting.

[0027] In the above description, the arc-shaped pressing plate is located inside the cylindrical casting, and the second support rod is fixed by bolts, thereby fixing the arc-shaped pressing plate.
