One-time molding crimping device for composite insulators

Abstract

The invention relates to a one-time forming pressing device for composite insulators. The one-time forming pressing device comprises a rack, a working platform and a drive cylinder. The working platform is installed inside the rack and comprises an upper fixed platform body and a lower movable platform body. Core rod limiting blocks are distributed on the lower surface of the upper fixed platform body. Guide holes are formed in the four corners of the upper fixed platform body. Core rod supporting blocks, fitting pressing plates, guide rods and a platform fixing base B are distributed on the upper surface of the lower movable platform body, the two core rod supporting blocks are arranged in total and symmetrically distributed at the two ends of the long axis direction of the lower movable platform body, the core rod supporting blocks and the core rod limiting blocks are combined to form a limiting hole for containing a fixing core rod, the fitting pressing plates are arranged at the two ends of each core rod supporting block, and the guide rods matched with the guide holes are installed on the upper surface of the lower movable platform body. The one-time forming pressing device has the advantages that the composite insulators with the small length can be formed and pressed at one time, and the device is very convenient to use.

Description

technical field [0001] The invention relates to crimping equipment, in particular to a composite insulator forming crimping device. Background technique [0002] Composite insulators are a special insulation control that can play an important role in overhead transmission lines. In the early years, insulators were mostly used on utility poles. With the development of science and technology, many disc-shaped insulators were hung on one end of the high-voltage wire connection tower. It is to increase the creepage distance. It is usually made of glass or ceramics. called insulators. Insulators play two basic roles in overhead transmission lines, namely supporting wires and preventing current from returning to the ground. These two functions must be guaranteed. Insulators should not fail due to various electromechanical stresses caused by changes in the environment and electrical load conditions. Otherwise, the insulator will not play a significant role, and it will damage the...

AI Technical Summary

Problems solved by technology

[0004] In the production process of composite insulators, in the process of crimping some insulators with relatively long lengths, the total length is about 30cm. Therefore, it is not convenient to use traditional large-scale crimping equipment for crimping, and because It is relatively short, so the staff needs to hold the mandrel for crimping, which is labor-intensive, and sometimes it is necessary to align the flange holes at both ends of the fitting, and the work efficiency is not high
