Manufacturing technology for ultra-large split ring piece

Abstract

The invention discloses a manufacturing technology for an ultra-large split ring piece. The manufacturing technology comprises the steps that the number, size and allowance design of a whole ring piece and the manufacturing technology of the whole ring piece are determined according to the subsection number, cross section characteristics and detection requirements of the ultra-large split ring piece, lifting technology excess materials and other elements, the whole ring piece is cut according to the designed number of split ring sections and then subjected to shaping machining through a special tool, the shaped ultra-large ring sections are marked out according to the finally designed ring section shape and size and then subjected to cutting machining, and finally, the cut ring sections are machined according to the size and shape of a final product. In this way, through the manufacturing technology for the ultra-large split ring piece, the split ring piece with the any split ring section number and the ultra-large diameter can be manufactured, the allowance design and production efficiency are better than those of a traditional free forging technology, limitation to the equipment is small, and the manufacturing technology has the advantages of being obvious low in cost, high in efficiency and capable of being easily applied and popularized to existing common ring rolling equipment, and is suitable for production of various ultra-large split ring piece products.

Description

technical field [0001] The invention relates to the technical field of manufacturing super-large split rings, in particular to a manufacturing process for super-large split rings. Background technique [0002] At present, there are two main methods for the manufacture of super-large split rings: one is to forge the billet into a rectangular bar with a rectangular cross-section by free forging, and then use a press to gradually bend the rectangular bar on a mold with a specific radian. The body ring segment is then machined into shape; another way is to use super-large ring rolling equipment to manufacture the super-large ring as a whole, and then cut it into required split ring segments after completion. [0003] From the analysis of the above two process schemes, it can be seen that the first method (hereinafter referred to as the free forging scheme), due to the large free forging allowance, long process cycle, difficult control of operation quality, and low production eff...

Problems solved by technology

[0003] From the analysis of the above two process schemes, it can be seen that the first method (hereinafter referred to as the free forging scheme), due to the large free forging allowance, long process cycle, difficult control of operation quality, and low production efficiency, especially in split It is more obvious when the arc of the ring is large and the number is large, and it is rarely used at present

[0004] The second method (hereinafter referred to as the overall ring rolling solution), although the production efficiency is higher, but it requires high rolling force and control ability of the ring rolling equipment, especially for ring rolling equipment over 10 meters long, the investment cost is very high

Therefore, this solution will inevitably bring higher manufacturing costs, and does not give full play to its due advantages in the production of super-large split rings

[0006] Therefore, for the manufacture of such super large split ring products, the above two process schemes have their shortcomings and shortcomings, which are not conducive to the engineering application of super large split ring products
