Die pressing method and device for blank of porcelain insulator

Abstract

The invention discloses a die pressing method and a device for a blank of a porcelain insulator. A cylindrical mud material is prepressed into a cake shape by using a die. The die pressing method and the device for the blank of the porcelain insulator are characterized in that a blank of a porcelain insulator, which has a designed shape, is obtained by die pressing; and the blank rotates continuously in the die pressing process so as to prevent that the appearance of the blank is destroyed because the blank is stuck to fall off by the die during stripping. According to the process disclosed by the invention, the use quantity of the mud material can be lowered by 30 percent, the efficiency is enhanced by 20 percent, and the defective rate of a product is lower than 5 percent. Compared with the prior art, the die pressing method and the device for the blank of the porcelain insulator have the following advantages that: (1) the strength of the manual operation is lowered; (2) the product has high accuracy and stable quality; (3) the number of applicable products is large; (4) the production efficiency is enhanced; and (5) the use quantity of the mud material is lowered, and the cost of the product is lowered.

Description

technical field [0001] The invention relates to a molding method and device for a porcelain insulator blank, belonging to the technical field of porcelain insulator processing. Background technique [0002] At present, the blank processing of disc-shaped porcelain insulators is usually done by extruding the mud material, rough pressing it into a block, and then manually processing the inner surface of the porcelain insulator on the spinning machine with a knife, and then manually transporting it from the spinning machine to trimming machine, and turn over the porcelain insulator blank, and then manually process the outer surface of the porcelain insulator with a tool. The disadvantage is that most of the processes are manually operated, the equipment is outdated, and the labor intensity is high. The product quality is mainly judged by the experience of the operators, the quality is not stable enough, the yield is low, and the work efficiency is also very low. Simultaneously...

The disadvantage is that most of the processes are manually operated, the equipment is backward, the labor intensity is high, the product quality is mainly judged by the experience of the operator, the quality is not stable enough, the yield is low, and the work efficiency is also very low

At the same time, in the existing technology, most of the mud of the billet is scratched away by the tool during processing, and the waste is serious
