Problems solved by technology

[0004] The purpose of the present invention is to overcome the shortcomings in the prior art. In order to reduce waste and save costs, solve the problem that polygonal rings cannot be processed or repaired. As long as polygons appear in the ring rolling process, they can only be scrapped. Therefore, polygonal shaping tooling is used , to make minor adjustments to the size of a point that does not meet the requirements

Embodiment Construction

[0024] The specific implementation manners of the present invention will be described below in conjunction with the accompanying drawings.

[0025] The invention discloses a polygonal ring shaping device, which comprises a ring blank 8 and an oil pressure system. The end of 6 is provided with a plug 3, the ring blank 8 is arranged between the plug 3 and the positioning column 4, and the oil cylinder 5 is connected with the hydraulic system.

[0026] The plug 3 is in the shape of an outer arc, and the plug 3 is fixedly connected to the end of the oil cap 6 .

[0027] The oil cylinder 5 is fixedly connected with the base 1 through the fixing seat 2 .

[0028] Two positioning posts 4 are arranged, and the two positioning posts 4 are arranged symmetrically around the center line of the top of the oil 6 , and the positioning posts 4 are fixedly connected with the base 1 .

[0029] A set of parallel irons 7 is arranged between the base 1 and the ring blank 8 .

[0030] One group ...

Abstract

The invention discloses a polygonal ring piece shaping device and method. The method comprises the following steps that the position of a ring piece blank needing to be shaped is measured and marked; a to-be-shaped ring piece blank is placed on the base, and the marked ring piece blank is placed between the ejector head and the positioning column; a sizing block with the proper height is selected, and the workpiece is kept horizontal; an oil pressure system is opened, an oil jack is aligned with the marked position for jacking, the size of the oil jack is changed, and therefore the size requirement is met; after shaping is completed, the measuring tape is used for preferentially measuring the size adjustment condition again, and the dial indicator for the vertical lathe is used for confirmation again after measurement of the measuring tape is qualified; and after confirmation, heat treatment is carried out to remove stress, and turning can be carried out. According to the shaping method, scrapped workpieces are saved, meanwhile, the performance requirements of the workpieces are not affected, and the shaping method has the advantages of being short in repairing time and low in cost.

Description

technical field [0001] The invention relates to the technical field of ring forging processing, in particular to a polygonal ring shaping device and a shaping method for repairing irregular polygons in the ring. Background technique [0002] Ring forgings are widely used, mainly involving wind power, petroleum refining, cement rotary kiln tires, state grid UHV high-diameter flanges, nuclear power and other fields. Ring rolling machine ring rolling is an important step in the production of ring forgings. At present, there are problems in the ring rolling process of ring forgings: 1) Due to external factors such as operator or equipment failure, it is easy to roll rings to form polygonal rings; 2) Due to the small margin of the ring formed by ring rolling, the ring rolling cannot be re-formed, and the workpiece can only be scrapped, which causes a lot of cost waste, which is the deficiency of the prior art. [0003] The invention patent application with the application number...
