Description

Technical Field

[0001] The utility model relates to the technical field of curved surface rubber wire pre-bonding tooling, in particular to a curved surface rubber wire pre-bonding tooling for a cylindrical annular frame. Background Art

[0002] In the field of vulcanization molding technology, the basic implementation method is that employees put the cylindrical ring skeleton with adhesive and the preformed rubber into the mold for vulcanization operation. In the actual operation process, the preformed rubber itself cannot be accurately positioned due to its nature, which causes the following problems: 1. It is inconvenient for personnel to operate, and the position of the rubber needs to be confirmed every time. 2. Since the rubber of the cylindrical ring skeleton is on the side wall, a slight deviation in the placement of the preformed rubber may cause a lack of glue in some parts of the product, resulting in unqualified products and losses. 3. In order to ensure the authenticity rate and reduce the lack of glue, many products have to increase the quality of the preformed rubber, resulting in a decrease in the effective utilization rate of the rubber and an increase in costs.

[0003] Designing a universal tooling that integrates the preformed rubber and the cylindrical ring frame, does not require confirmation of the rubber position, and can accurately position on the curved surface of the cylindrical ring frame to reduce costs is an inevitable requirement for factory production.

[0011] 3. Precise positioning of the preformed rubber strip and the frame can be achieved according to different actual product applications, and the rubber can be placed in a reasonable position as much as possible, with higher and better rubber utilization rate;

[0012] 4. The preformed rubber material and the cylindrical ring frame are integrated into one piece and only need to be loaded once, without the need to load them separately. BRIEF DESCRIPTION OF THE DRAWINGS
