Processing method of pneumatic rubber capsule special for petroleum drilling machine

Abstract

The invention discloses a processing method of a pneumatic rubber capsule special for petroleum drilling machine. The method consists of six technical steps: rubber mixing, calendaring cutting, extrusion, molding, vulcanization, and packaging, etc. In the vulcanization step, liquid water is injected into a pneumatic rubber capsule by a high-pressure pump, the pressure is controlled by a pressure gauge, thus replacing the steam pressurization used by traditional vulcanization, increasing the internal pressure of the pneumatic rubber capsule during vulcanization, increasing the density of the pneumatic rubber capsule, and optimizing the product quality of the processed pneumatic rubber capsule. Also a pneumatic rubber capsule automated die on a vulcanization machine is adopted during vulcanization production, the vulcanization temperature, time and pressure are adjusted, so that in the production process, the die can achieve accurate die closing, die opening and lifting positioning, thus fundamentally solving the time consuming and labor consuming problems. In addition, liquid water is low in cost and can be recycled, so that the production cost of enterprises can be significantly reduced.

Description

[0001] 1. Technical field: [0002] 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. [0003] 2. Background technology: [0004] 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 vulcanizatio...

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
