Problems solved by technology

[0002] In the past, composite insulator hardware (steel feet) were processed by lathes; milling machines were used for processing and production, but iron filings splashed during the processing were prone to injury accidents, which was unsafe. At the same time, there were many processing procedures and complex processes, and a lot of waste was generated during the cutting process. , the cutting process takes a long time and the cost is high; in order to save time, some people currently use the forging forming production process. This process requires heating the blank first. If the control is not good, it will lead to overheating of the material, surface oxidation and decarburization, and thermal cracks. , Surface hardening, large differences in mechanical properties and other defects, unstable quality, and follow-up needs finishing, low production efficiency, long production cycle, unable to form mass production. Can not meet market demand

Embodiment Construction

[0053] Referring to the accompanying drawings, the one-time molding process of the lower end fittings of the composite insulator is specifically in the following production steps:

[0054] 1) if Figure 27 , firstly, the steel plate material is transported to the feed port of the cold heading machine, and the steel material is sent to the blanking mold by the automatic feeding roller of the cold heading machine, and the blank of the required length is designed through the reciprocating motion stroke of the cold heading machine head Automatic cutting, and finally the cut blank is ejected by the ejector pin in the blanking die;

[0055] 2) if Figure 28 , the cut blank is sent to the mold of the second working step through the built-in manipulator of the cold heading machine, and the built-in manipulator automatically leaves and resets through the linkage mechanism, and the cut blank is cooled in the second working step mold through the reciprocating motion stroke of the headin...

Abstract

The invention relates to a one-time precision forming process for the lower end fittings of a 10kV pin-type composite insulator. Described mold comprises the mold of five stations, is respectively blanking mould, second working step mold, third working step mold, fourth working step mold and fifth working step mold, and five working station molds are all formed by upper The die head and the lower die are respectively installed and fixed on the upper die base and the lower die base in sequence. The upper and lower die bases are integrated and fixed respectively on the upper and lower workbenches of the cold heading machine. There are five stations. The rear end of the lower mold is respectively equipped with discharge ejector pins. The advantages are ingenious design, convenient operation, time saving, manpower saving, material saving, safety and reliability, high precision, good quality, low cost and high efficiency.

Description

technical field [0001] The invention relates to the field of composite insulator hardware production, in particular to a one-time precision forming process for composite insulator lower end hardware (steel legs). Background technique [0002] In the past, composite insulator hardware (steel feet) were processed by lathes; milling machines were used for processing and production, but iron filings splashed during the processing were prone to injury accidents, which was unsafe. At the same time, there were many processing procedures and complex processes, and a lot of waste was generated during the cutting process. , the cutting process takes a long time and the cost is high; in order to save time, some people currently use the forging forming production process. This process requires heating the blank first. If the control is not good, it will lead to overheating of the material, surface oxidation and decarburization, and thermal cracks. , Defects such as surface hardening and...
