Abstract

It relates to the glue sleeve seal teeth shape reversed V shape forming sulfuration. It makes belt blank at the inner mold, installs the round cylinder glue sleeve with teeth on the surface inside and smooth surface inside both ends on the glue sleeve base and fastened with shrouding rings, putting them into sulfur can, hanging belt blank into glue sleeve, covering the top cap and the cap of the sulfur can, sequentially opening the outside pressure and inner pressure steam for sulfuration, stripping the belt blank round cylinder with vertical rack outside and the cutting belt blank round cylinder, getting many teeth shape cutting V belt. It solves the sealing issue at both ends of the glue sleeve, eliminating the bubbling stratification defect of the product, increasing effective cutting 2-4 lines, reducing material consumption and cost.

Description

technical field

[0001] The invention discloses a reverse molding vulcanization method of a rubber-sleeve-sealed tooth-shaped edge-cut V-belt, relating to a manufacturing process of a tooth-shaped edge-cut V-belt. Specifically, using the reverse forming process, first paste cloth, glue, rope core, paste compressed rubber and base cloth on the smooth cylindrical inner mold to make the strip blank, and then press the strip blank with a rubber sleeve with internal teeth and enter the vulcanization cylinder Vulcanized, and finally demolded and cut into product V-belts. Background technique

[0002] The toothed cut edge V-belt is a kind of transmission belt. As an important component in the field of mechanical transmission, this toothed edge-cut V-belt has been widely used in automobiles, motorcycles, etc. There are two methods of making V-belts with toothed edges: positive forming and reverse forming. The positive forming process is to first use a cylindrical steel mold with t...

Embodiment Construction

[0021] See Figures 1-4.

[0022]First select the steel pipe required by the design size as the inner mold 5 of the present invention, and process the inner mold 5 into a light mold with smooth surface and no tooth profile. Then put a trademark on the surface of the smooth cylindrical inner mold 5, wrap the top cloth 8, then wrap the top glue 9, then wrap the cushion glue 10, then wrap the core rope 11, then wrap the cushion glue 10, and finally wrap the bottom glue 12 Pack base cloth 13 again, finish the task of making band base 4 with reverse forming method. Make rubber cover 3 then, and rubber cover 3 is the outer mold of product. The tooth shape and structure of the rubber sleeve 3 are specially designed. The inner surface of the middle part of the rubber sleeve 3 has teeth, and the inner surfaces of both ends are smooth and cylindrical. The tooth shape of the inner surface of the rubber sleeve 3 is made by a specially designed mold according to the actual situation of t...
