The V-belt is a power belt or a transmission belt which transmits power generated by the rotation of a motor or an engine of a prime mover to mechanical equipment through a belt wheel, and has the advantages of free speed change, far and near transmission, simple structure, convenience in replacement and the like. The V-belt is used as a core connecting component of electromechanical equipment and is widely applied to various fields of automobiles, machinery, textiles, household appliances, light industry, agricultural machinery and the like.
The existing V-belt production process is various, but generally comprises the following steps: mixing the rubber layer, rolling the rubber layer, forming, cutting, vulcanizing and the like. The cross section of the V-belt is a trapezoidal annular transmission belt, so that in the process of processing the V-belt, a formed adhesive tape or blank belt needs to be cut into V-belt cores with certain inclination angles at two sides, so that the V-belt with certain chamfers is formed. However, in the existing production process, no special V-belt core chamfering equipment is provided, and the V-belt core chamfering is often directly cut on a forming cutting machine. Because the forming cutter needs to finish two works of belt core cutting and belt core chamfering simultaneously, the belt core chamfering is often inaccurate in cutting, and the quality of the V belt is seriously influenced.
