Description

Technical Field

[0001] The utility model relates to the technical field of stainless steel silencers, in particular to a special roller for stainless steel shrinking. Background Art

[0002] With the skyrocketing copper prices, the competitiveness of the copper accessories market is becoming increasingly fierce, and the industry is becoming more difficult to survive. More and more people are beginning to explore the stainless steel silencer process. When shrinking stainless steel, the cracking rate of the traditional shrinking tool pipe reaches 20%, and the cost is unaffordable for enterprises. How to reduce the cracking problem of stainless steel pipe shrinkage is an important issue that needs to be urgently solved in the industry. Utility Model Content

[0003] The technical problem to be solved by the utility model is to overcome the existing defects and provide a special roller for stainless steel shrinking. The roller has a simple structure and can greatly reduce the cracking and scrapping rate of the pipe mouth when the stainless steel is shrinking, greatly reduce the cost, improve the physical quality, enhance the competitiveness of the enterprise, and can effectively solve the problems in the background technology.

[0004] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a special roller for stainless steel shrinking, comprising a roller, wherein the interior of the roller is connected with deep groove bearing one and deep groove bearing two by interference fit, both ends of the interior of the roller are provided with installation matching cavities corresponding to deep groove bearing one and deep groove bearing two, and the inner rings of deep groove bearing one and deep groove bearing two are connected with fixing bolts by interference fit.

[0005] Furthermore, the outer side of the T-shaped boss of the roller is configured as an arc-shaped surface structure.

[0006] Furthermore, the inner ring diameter of the deep groove bearing one is larger than the inner ring diameter of the deep groove bearing two, the outer side of the fixing bolt is a boss-like structure, the outer side of the fixing bolt corresponds to the deep groove bearing one and the deep groove bearing two, and one end of the fixing bolt is provided with an integrally connected screw head.

[0007] Compared with the prior art, the beneficial effects of the utility model are as follows: during assembly, the deep groove bearing one and the deep groove bearing two are correspondingly installed inside the mounting matching cavity of the roller, and then the deep groove bearing two is correspondingly installed between the rollers and the fixing bolts are clamped and installed. The special roller for stainless steel shrinking has a simple structure, can greatly reduce the cracking and scrapping rate of the pipe mouth when the stainless steel is shrinking, greatly reduces the cost, improves the physical quality, and enhances the competitiveness of the enterprise.
