Processing method of forged bowl head hanging plate

Abstract

The invention provides a processing method for a forged socket clevis. The processing method is characterized by comprising the following processes of: A, feeding; B, upsetting to prepare blank; C, integrally forging a product outline; D, cutting raw edges; E, punching socket holes, wherein a dually-linked socket punching mould of the forged socket clevis is adopted; F, grinding burrs; and G, performing hot galvanizing. Carbon structural steel with a trade mark of Q235A is selected during feeding. In order to overcome the defects in the prior art of the socket clevis, materials are reasonably selected, the product structural design is improved, and casting is changed into an integral forging production process; and the mould is selected to solve the problem that product mechanical strength is affected by casting internal defects and the problems that a production process is high in energy consumption, has pollution on environment, and is low in working efficiency.

Description

technical field [0001] The invention belongs to the processing method of connecting fittings of electric power lines, and in particular relates to the processing method of single-connected bowl head hanging plate. Background technique [0002] Such as figure 1 , figure 2 , image 3 , Figure 4 As shown, the ball-socket part 41' of the bowl head hanging plate 4' is used to connect the steel foot 31' (also known as the ball head) at the lower end of the ball-and-socket insulator 3', and the hanging plate part 43' is used to connect the suspension on the straight pole tower. The wire clamp 5' is used to connect the tension wire clamp 5' on the corner terminal tower. The bowl head hanging plate is one of the important connecting fittings for overhead power lines. It bears all the load and tension of the wire and should have sufficient mechanical strength. The invention selects the advanced production technology with low energy consumption and the bowl-head hanging plate fo...

AI Technical Summary

Problems solved by technology

[0005] In the prior art, coke is used for smelting cast iron, and clean coal is used for annealing treatment. These two processes consume more than 600 kilograms of coal per ton of product, which is a high energy-consuming production process, and the production process produces smoke and dust, which affects the atmospheric environment.

The strength of malleable cast iron is lower than that of ordinary carbon structural steel, and the quality stability of the two special processes of smelting and annealing heat treatment in the production process is poor, internal defects of castings are not easy to find, and the product may potentially break during use.

Casting is a labor-intensive production process, with many processes, low production efficiency, and high wage content in production costs
