Manufacture method for silicon rubber synthetic insulators and umbrella slice sleeving machine

Abstract

The invention relates to a manufacture method for silicon rubber synthetic insulators and an umbrella slice sleeving machine, belonging to the technical field of insulator production. The method comprises the steps of preparing a rubber rod and sleeving umbrella cluster umbrella slices on the rubber rod, and is characterized in that a rubber rod sleeve is prepared, and the rubber rod is put in the rubber rod sleeve; the umbrella cluster umbrella slices are well arranged in umbrella slice dies, and the rubber rod sleeve is drawn out from an umbrella cluster; the rubber rod sleeve drives the rubber rod to a set position, stops the rubber rod from moving on and is separated from the rubber rod, and the umbrella cluster umbrella slices slide on the rubber rod to finish the positioning fixation of the umbrella cluster umbrella slices and the rubber rod. The umbrella slice sleeving machine is simple and convenient to operate, is easy to learn, has high production efficiency and rate of finished products, good product quality, simple structure and convenient use, the umbrella slice dies are arranged on a stand, the rubber rod sleeve, a traction rod and a rubber rod motion limit block are arranged corresponding to the umbrella slice dies, and the rubber rod sleeve and the traction rod are movably connected.

Description

technical field [0001] The invention relates to a method for manufacturing a silicon rubber synthetic insulator and an umbrella sheet fitting machine, belonging to the technical field of insulator production. Background technique [0002] The silicone rubber synthetic insulator, the umbrella group and the rubber rod are vulcanized or glued into one, forming an interference fit and tension bonding. Its production methods are basically divided into three types: [0003] The first method: integral injection or segmental injection [0004] Put the mandrel into the mold cavity, and mold it by injection after closing the mold. If the insulator is too long, inject it in sections. [0005] The second method: integral molding or segmental molding [0006] Put the mandrel and the mixed silica gel into the forming mold, press the mold after closing the mold. [0007] The third method: Umbrella adhesive [0008] Umbrella group umbrella pieces and glue sticks are formed and vulcaniz...

AI Technical Summary

Problems solved by technology

[0009] Among these three methods, integral injection and integral molding have disadvantages such as low production efficiency, low yield, large waste of raw rubber, and longitudinal mold joints.

Especially for these two methods, due to the high pressure in the cavity and the flow of raw rubber, the resin mandrel becomes soft during the heating and molding process of the insulator, and the glue stick is eccentric, which seriously affects the quality of the insulator.

However, in the umbrella-through adhesive method, when the glue stick is pushed into the umbrella group umbrella piece, due to the interference fit between the two, there will be a lack of glue between the umbrella group umbrella piece and the glue stick, and it is necessary to manually adjust the umbrella , Applying glue, it is easy to cause inaccurate spacing of umbrellas, uneven glue application, easy to fall off and other bad phenomena in the use of hanging wires, which also affects the quality of insulators
