Manufacturing method of separate rubber-covered roll

Abstract

The invention relates to a manufacturing method of a separate rubber-covered roll. The manufacturing method comprises a method for constructing and manufacturing a prefabricated rubber sleeve and an implementing method of fixing and clearance potting of the prefabricated rubber sleeve and a working roll blank. The invention provides the manufacturing method of the separate rubber-covered roll. The manufacturing method is mainly characterized in that a separate rubber cylinder with a special structure is prefabricated through a specific technology, then the prefabricated rubber sleeve and the working roll blank are fixed with the aid of a special tool, a gap between the prefabricated rubber sleeve and the working roll blank is filled by low-viscosity epoxy resin potting adhesive, and after curing, a whole body is formed. After the whole body is formed, followed-up grinding machining of the whole body is the same with that of an integral type rubber-covered roll. By the method, restriction of logistics transportation conditions to the rubber-covered roll manufacturing industry can be greatly weakened; and meanwhile, rubber-covered manufacturing standardization level can be increased, production flow is simplified and shortened, manufacturing period is shortened, management is optimized, quality risks are reduced, and energy consumption is reduced. The manufacturing method of the separate rubber-covered roll provides references for development modes of the rubber-covered roll manufacturing industry in the future.

Description

technical field [0001] The invention relates to a method for manufacturing a split rubber roller. Background technique [0002] The current rubber rollers are usually manufactured as a whole, that is, the metal roll blank (hereinafter referred to as the work roll blank) and the rubber material are processed in the factory by specific mechanical treatment on the surface, setting a specific adhesive coating, and covering the rubber roll. material, and then the work roll blank and the coated rubber material are heated and pressurized together for vulcanization, subsequent turning and grinding processes, and finally the rubber roller product is obtained. If the above process is collectively called "coating", the complete production chain of the integral rubber roller can be briefly described as follows: [0003] Obtain the work roll blank through logistics→covering→send the finished rubber roll (work roll blank + cover surface layer) to the customer through logistics. This mod...

AI Technical Summary

Problems solved by technology

This mode has the following problems: 1. The production organization (coating) needs to be carried out after the work roll blank arrives at the site, which has poor initiative and low standardization; 2. Round-trip logistics transportation, the actual delivery time is long; 3. The heavy work roll blank The rubber roller becomes a vulnerable part of the logistics, the logistics pressure is high, and the logistics cost is high; at the same time, the heavy work roll blank is used as the carrier of the rubber coating, and it is transported back and forth, which is very wasteful; 4. The heavy work roll blank is used as the rubber coating carrier and participates in heating Vulcanization is a waste of energy; 5. The heavy work roll billet needs supporting lifting and transfer tools, which increases the investment in factory hardware; 6. Logistics pressure, cost and the resulting pressure on delivery time restrict the rubber roller to a certain extent Enterprise service scope and business development
