Description

Inner circle shaping tool for cylinder

Technical Field

The invention relates to auxiliary processing equipment for a vacuum container, in particular to a cylinder inner circle shaping tool.

Background

In the production and manufacture of vacuum vessels, a plurality of vacuum vessel cylinders are large in diameter and thick, some large sections of cylinder joints are formed by splicing a plurality of plates, each plate is prefabricated and rolled in advance, then assembly welding is carried out, the whole roundness of the cylinder is influenced by welding deformation after welding is finished, although some measures are also adopted inside the cylinder during welding to prevent the cylinder from deforming due to the influence of welding, the cylinder deforms certainly when being welded, and the spliced cylinder is inconvenient to take to a plate bending machine for shaping due to the large diameter.

Disclosure of Invention

The invention aims to provide a cylinder inner circle shaping tool, which solves the problem that a cylinder with a larger diameter is inconvenient to shape an inner circle in the prior art.

In order to achieve the purpose, the invention adopts the following technical scheme:

the utility model provides a circle plastic frock in barrel, its includes that interior circle supports, be radially fixed with a plurality of spinal branch vaulting poles in the interior circle supports, all be provided with the movable sleeve on the every spinal branch vaulting pole, be provided with between movable sleeve and the bracing piece and be used for the spacing subassembly fixed with both, just movable sleeve's tip can movably install accommodate the lead screw, accommodate the lead screw's end fixing has big nut.

Particularly, the inner circle support is of a cylindrical structure, and the wall thickness of the inner circle support is greater than 50 mm.

Particularly, the limiting assembly comprises a bolt, a plurality of bolt holes are correspondingly formed in the movable sleeve and the supporting rod along the length direction, and the bolt is inserted into the corresponding bolt holes in the movable sleeve and the supporting rod to fix the movable sleeve and the supporting rod.

Particularly, the support rods are uniformly distributed and welded on the outer wall of the inner circle support, the diameter of the support rods is 80 mm-120 mm, and the length of the support rods is less than 1000 mm.

In particular, the length of the mobile bushing is less than 1500 mm.

Particularly, the aperture of each plug hole is 30mm, and the distance between every two adjacent plug holes is 100 mm.

Compared with the prior art, the cylinder inner circle shaping tool has the advantages of simple structure and ingenious design; and the shaping of the large-diameter cylinder body has good effect, is convenient to operate and can be disassembled, and the shaping device is very suitable for the field manufacture and use of large-scale equipment.
