Production method of capsule for energy accumulator

Abstract

The invention provides a production method of a capsule for an energy accumulator. A raw rubber material is adopted to manufacture a cylindrical rubber sleeve, a rear sealing piece, a front sealing piece and an inner sealing piece through extrusion and hacking processes, wherein the middle of the front sealing piece is provided with a circular hole, and the middle of the inner sealing piece is provided with a circular hole; edges of the rear sealing piece and the front sealing piece with the inner side being connected with an inlet end socket and the inner sealing piece in a bonded mode are turned over and then fixedly connected to the exteriors of the two ends of the rubber sleeve through a bonder to constitute a capsule blank of the raw rubber material; and the capsule blank is placed into a lower mold cavity, the inlet end socket is located in a semicircular groove in a lower mold body and fixedly connected with an air feeding pipeline, after an upper mold body and the lower mold body are assembled, high-temperature steam is charged through an inlet joint, the capsule blank is expanded to be tightly attached to an inner cavity of a mold and heated by the high-temperature steam or hot air to be vulcanized, and the capsule of the overall structure is constituted. The rubber sleeve, the rear sealing piece and the front sealing piece do not need to be vulcanized respectively, polishing is also not needed after bonding, a joint is flat and smooth, the appearance is attractive, working procedures are reduced, a production process is simple, secondary vulcanization is also notneeded, material properties are stable, the quality is reliable, the consumed time is less, and thus the production efficiency is improved.

Description

technical field [0001] The invention relates to a production method of a capsule for an accumulator. Background technique [0002] Capsules for traditional accumulators are generally composed of two ends of the rubber cylinder connected to the front and rear heads, and the middle part of the front head is fixed and wrapped with an inner seal to install the inlet joint. During production, the rubber cylinder must first be made and vulcanized, and then the back seal is made. The cover is vulcanized and formed, and then the front seal, inner seal and inlet joint are vulcanized and molded together, and the rubber cylinder, rear seal and front seal are respectively polished, and the rear seal and front seal are respectively bonded and connected to the rubber Both ends of the barrel, and finally heat the secondary vulcanization molding in the mold. There are many procedures, the production process is complicated, and it takes a long time. The rubber barrel, the rear cover, and the...

[0002] Capsules for traditional accumulators are generally composed of two ends of the rubber cylinder connected to the front and rear heads, and the middle part of the front head is fixed and wrapped with an inner seal to install the inlet joint. During production, the rubber cylinder must first be made and vulcanized, and then the back seal is made. The cover is vulcanized and formed, and then the front seal, inner seal and inlet joint are vulcanized and molded together, and the rubber cylinder, rear seal and front seal are respectively polished, and the rear seal and front seal are respectively bonded and connected to the rubber Both ends of the barrel, and finally heat the secondary vulcanization molding in the mold. There are many procedures, the production process is complicated, and it takes a long time. The rubber barrel, the rear cover, and the front cover are vulcanized and molded separately, and then glued and polished, and the production efficiency is low. ;The rubber tube, the rear head, and the front head are bonded and connected as one. After secondary vulcanization, they are prone to become brittle, and performance indicators such as elongation and tensile strength will decrease; gluing and grinding will also make the joints uneven. The appearance is not beautiful, and the rubber performance index is greatly reduced compared with the one-time vulcanization.
