One-step forging die of porcelain insulator cap

Abstract

The invention relates to a one-step forging die of a porcelain insulator cap. The one-step forging die mainly comprises an upper die and a lower die. The upper die mainly comprises a lock insert, a lock insert cylinder, a forming die, an upper moving platform and an upper base. The upper moving platform is disposed at the lower end of the upper base. The lock insert and the forming die are disposed at the bottom of the upper moving platform. The lower die mainly comprises a lock cylinder, a lock cylinder holder, a lower moving platform, a washer and a lower base. The lock cylinder holder sleeves outside the lower moving platform. The washer is disposed between the lower moving platform and the lower base. The middle of the lower moving platform is provided with a forming cavity corresponding to the forming die. The one-step forging die has the advantages that the die is available for one-step forging molding, production cost is reduced, work efficiency is improved, emission of three wastes is reduced, the defects such as shrinkage, sand holes and cracks caused during forging can be casting, and products can be more reliable.

Description

technical field [0001] The invention relates to a one-time forming die for forging an iron cap of a porcelain insulator, in particular to a one-time forming die. Background technique [0002] Ceramic insulators: have the advantages of good insulation performance, weather resistance, heat resistance and flexible assembly, and are widely used in lines of various voltage levels. Porcelain disc insulators are punctureable. They are composed of ceramic parts with different physical and chemical properties and metal parts. The effects of rain, snow, fog, etc. will gradually deteriorate and pose a threat to the safe operation of the power grid. Especially when the insulator string containing degraded insulators has a flashover (due to lightning strike or pollution flashover, etc.), the head of the degraded insulator may instantly heat up and explode, resulting in an accident where the wire falls to the ground. [0003] At present, in the existing production process, when forging ...

AI Technical Summary

Problems solved by technology

Porcelain disc insulators are punctureable. They are made of porcelain and metal parts with different physical and chemical properties. The effects of rain, snow, fog, etc. will gradually deteriorate and pose a threat to the safe operation of the power grid

Especially when insulator strings containing degraded insulators have flashover (due to lightning strikes or pollution flashovers, etc.), the head of the degraded insulator may instantly heat up and explode, resulting in accidents where the wires fall to the ground

[0003] At present, in the existing production process, when forging the iron cap of porcelain insulators, the casting process is currently used in China, and the products produced by the casting process inevitably have defects such as shrinkage porosity, sand holes, and cracks.
