Precise tooth socket mold and vulcanization technology for producing trimming cut V-belts therewith

Abstract

The invention belongs to the technical field of vulcanized molds and discloses a precise tooth socket mold and a vulcanization process for producing trimming cut V-belts therewith. The vulcanization pThe invention belongs to the technical field of vulcanized molds and discloses a precise tooth socket mold and a vulcanization process for producing trimming cut V-belts therewith. The vulcanization process comprises the following steps: sequentially winding top adhesive plaster, pasting buffer film, winding a strong layer thread rope and pasting an adhesive layer film and bottom anti-wear film ourocess comprises the following steps: sequentially winding top adhesive plaster, pasting buffer film, winding a strong layer thread rope and pasting an adhesive layer film and bottom anti-wear film outside a smooth round mold to form a strip stock; sleeving an ultrathin stainless-steel tooth socket film with the thickness of 0.2 mm to 0.3 mm and an adhesive sleeve outside the strip stock; and vulctside a smooth round mold to form a strip stock; sleeving an ultrathin stainless-steel tooth socket film with the thickness of 0.2 mm to 0.3 mm and an adhesive sleeve outside the strip stock; and vulcanizing at a pressure difference, stripping, cutting and grinding into circular V-shaped adhesive belts. The precise tooth socket mold molds tooth profile by a stainless-steel tooth socket, prevents tanizing at a pressure difference, stripping, cutting and grinding into circular V-shaped adhesive belts. The precise tooth socket mold molds tooth profile by a stainless-steel tooth socket, prevents the thread rope from greatly shrinking, solves the problem of different datum length of the same-mold adhesive belts, enables the adhesive belts to have little elongation, enables sizing material to hahe thread rope from greatly shrinking, solves the problem of different datum length of the same-mold adhesive belts, enables the adhesive belts to have little elongation, enables sizing material to have good compactness, good double-faced lustrousness and stable use quality and has the advantages of simplicity, rapidness and material and labor saving.ve good compactness, good double-faced lustrousness and stable use quality and has the advantages of simplicity, rapidness and material and labor saving.

Description

technical field [0001] The invention belongs to the technical field of vulcanization moulds, in particular to a precision alveolar mould, and a V-belt forming vulcanization process using the same to produce trimmed V-belts. Background technique [0002] There are two kinds of molds for manufacturing automotive engines and other industrial internal combustion engines or other toothed trimming V-belts on transmission systems. One is a cylindrical metal mold with alveolar. During manufacture, the bottom wear-resistant film, the bonding adhesive film, the winding rope, the buffer layer film, and the top adhesive tape are wound sequentially on the cylindrical metal alveolar mold. , Put on the rubber sleeve, and then put it into the vulcanization cylinder for differential pressure vulcanization. The other is to use the rubber alveolar rubber sleeve to press externally, and the inner wall of the rubber sleeve is made into a tooth-shaped groove. On the smooth round mold, the top ru...
