Problems solved by technology

[0003] One is that there are many links in the processing technology, and the deviation of each link has an impact on the quality of the entire product, and then the quality of the operator and the mentality of the on-duty staff have an impact on the quality of the product; thus the product quality is unstable and the pass rate is low , a large waste;
[0004] Second, due to the need to melt the steel produced, it consumes a lot of energy and pollutes the environment;
[0005] The third is that the thickness of each part of the cast steel cap is different. If the adjustment is not good on the assembly insulator, it will affect the quality of the factory product;
[0006] The fourth is that the traction button is easy to be eccentric during casting, so when the wire is assemb

Example Embodiment

[0032] The purpose of the present invention is given by the following examples:

[0033] In the first step, 235 steel plates are used to cut the barrel material and traction button material respectively;

[0034] In the second step, the cut material is placed in a special punching machine for thermal shock method for stamping; the pull hook 6 is stamped and formed at one time. When the pull hook 6 is inserted into the groove from the side of the cylinder 1, the riveting foot Processed into "I" shape; the cylinder 1 is stamped twice; the first stamping is made into a stalactite-shaped cylinder blank, and at the same time two grooves 5 are pressed at the upper end of the cylinder 1; the second time is with a special arc expanding stamping device Punch the lower end of the cylinder to form a 2-shaped arc socket at the lower end of the cylinder;

[0035] The third step is to assemble the stamped cylinder 1 and the traction hook 6; first, insert the riveting foot 4 of the traction hook 6...

Abstract

The invention discloses an insulator steel cap and a manufacturing method. The insulator steel cap is composed of two traction hanging buttons 6 and a cylinder body 1, wherein an upper end of each traction hanging button 6 is provided with a traction hanging hole 3, a lower end of each traction hanging button 6 is provided with riveting feet 4, a steel cap cylinder body 1 is stalactitic, an upperend of the cylinder body 1 is provided with two grooves 5 for installing and fixing the riveting feet 4 of the traction hanging buttons 6, a lower end of the cylinder body is a nest groove to preventthe rainwater from overflowing into an insulator. The part machining method is stamping manufacturing. The method is advantaged in that firstly, the weight is light, product quality standards are unified, the standard percent of pass can reach 99.9%, the process is simple, energy consumption is low, and the environment is not polluted; and secondly, potential safety hazards can be prevented, the rainwater cannot overflow into the insulator, and the product is long in service life, large in traction force, free of breakage and capable of being widely applied to assembly of insulators.

Description

technical field [0001] The invention relates to accessories and production of an insulator, in particular to a steel cap for an electric porcelain insulator and a production method. Background technique [0002] The steel cap of the electric porcelain insulator before the present invention is made by the method of casting, and the cylinder body of the steel cap and the pulling button are formed into one body by one-time casting. There are many deficiencies in this steel cap produced by the casting method. [0003] One is that there are many links in the processing technology, and the deviation of each link has an impact on the quality of the entire product, and then the quality of the operator and the mentality of the on-duty staff have an impact on the quality of the product; thus the product quality is unstable and the pass rate is low , a large waste; [0004] Second, due to the need to melt the steel produced, it consumes a lot of energy and pollutes the environment; ...
