Processing method of rubber gasbag special for petroleum drilling machine

Abstract

The invention discloses a processing method of a rubber gasbag special for a petroleum drilling machine. The processing method comprises six process steps of refining rubber, rolling and cutting, pressing, forming, vulcanizing and packaging, wherein in the vulcanizing process step, liquid water is injected into the rubber gasbag by a high-pressure pump and the pressure is controlled by a pressuregauge, so that steam pressurizing for the traditional vulcanization is replaced, the internal pressure of the rubber gasbag during vulcanization is increased, the density of the rubber gasbag is increased, the product quality of the processed rubber gasbag is optimized; furthermore, a rubber gasbag automatic mold on a vulcanization machine is adopted during vulcanization production, and vulcanization temperature, time and pressure are adjusted, so that the mold in the production process can perform mold closing, mold opening and lifting positioning accurately, and the problem that time and power are consumed by manual operation is solved; in addition, the liquid water is low in cost and can be recycled, so that the production cost of enterprises can be obviously reduced.

Description

technical field [0001] The invention relates to a production process of rubber products, in particular to a processing method of a special rubber air bag for an oil drilling rig. Background technique [0002] The production process of rubber airbags for drilling rigs includes six processes including rubber mixing, calendering and cutting, extrusion, molding, vulcanization, and packaging. Among them, the vulcanization process is a special key process. The temperature, time and pressure of vulcanization directly affect the quality of the product. At present, the vulcanization mode adopted by most enterprises at home and abroad is: use traditional vulcanization tanks for vulcanization, and use boilers to provide steam to vulcanize products, because vulcanization tanks cannot be quantified according to needs, especially in certain types of orders When the quantity is small or the demand for a certain product is small, the vulcanization of the vulcanization tank will consume a lo...

AI Technical Summary

Problems solved by technology

At present, the vulcanization mode adopted by most enterprises at home and abroad is: use traditional vulcanization tanks for vulcanization, and use boilers to provide steam to vulcanize products, because vulcanization tanks cannot be quantitatively determined, especially in certain types of orders When the quantity is small or the demand for a certain product is small, the vulcanization of the vulcanization tank will consume a lot of energy, resulting in waste of resources and increased production costs

In addition, due to the large size of the vulcanization tank itself, the whole process from loading to unloading requires the cooperation of multiple people, which wastes manpower and poses a great safety hazard
