Production technology of double-surface clipping V-shaped band

Abstract

The invention discloses a production technology of a double-surface clipping V-shaped band, comprising the following steps: 1) material preparing: taking raw rubber of a calendered adhesive, compounding agent of the calendered adhesive, raw rubber of a buffer glue, compounding agent of the buffer glue, raw rubber of a fiber primer, and compounding agent of the fiber primer and respectively weighing; 2) mixing; 3) calendaring; 4) reversing splicing: splicing the fiber primer reversingly; 5) shaping: successively coating a layer of base fabric, coating the fiber primer, coating the buffer glue, arraying wires, coating the buffer glue, coating the fiber primer, and coating a layer of top fabric; 6) vulcanizing: putting the shaped V-shaped band wholly in a mold, and putting the mold in a vulcanizing tank for vulcanizing; 7) clipping: controlling the clipping width and angle, and clipping the band into the required shape; and 8) grinding: controlling the grinding quantity, and grinding the band into the required dimension. According to the invention, the shaped V-shaped band is wholly put in the mold, and the mold with the V-shaped band is put in the vulcanizing tank for vulcanizing, thus the service life of the band is long, and the band is suitable for large power transmission.

Description

technical field [0001] The present invention relates to a V-belt production process. Background technique [0002] Double-sided V-belt, also known as hexagonal belt, is a ring-shaped rubber belt with hexagonal cross-section and four working surfaces, and the front and back sides are flexible. It is suitable for multi-axis transmission, especially for multi-wheel transmission. It is mainly used for transmission Small space, compact transmission occasions. The traditional hexagonal belt is in the form of wrapping structure. The forming process of the wrapping hexagonal belt is complicated. The semi-finished hexagonal shape of the semi-finished product has low production efficiency and complicated vulcanization process. Flat-plate vulcanization, and the uneven flow of the raw rubber material during vulcanization, it is easy to cause product deflection, that is, the authenticity rate is low. In addition, the edge-wrapped hexagonal belt has low lateral stiffness, large bending s...

AI Technical Summary

Problems solved by technology

The traditional hexagonal belt adopts the hexagonal structure. The molding process of the hexagonal belt is complicated. The formed semi-finished hexagonal shape has low production efficiency and complicated vulcanization process. Flat plate vulcanization, and due to the uneven flow of rubber material with the blank during vulcanization, it is easy to cause product deviation, that is, the rate of genuine products is low. The friction force of the surface is small and it is easy to slip. Generally, hexagonal belts are made of NR and SBR, which have a short service life and are not suitable for high-power transmission.
