Welding manufacturing method of large-scale cast-welded structure hoop cable clamp

Abstract

The welding manufacturing method of the large-scale cast-welding structure loop cable clamp of the present invention adopts welding materials and welding methods that match the cable clamp body and ear plates, controls the preheating before welding and the interlayer temperature, and selects appropriate welding process parameters to The cross cable lugs, membrane cable lugs and strut lugs are welded to the ring cable clamp body, which not only ensures the mechanical properties of the welded joints, but also greatly improves the production efficiency and saves manufacturing time; adopts groove design and welding sequence control Measures such as these ensure the manufacturing and installation accuracy of the weld seam of the hoop and cable clamp and reduce welding deformation; the method of overall stress relief annealing after welding reduces the internal stress of the weld seam and the entire cable clamp.

Description

technical field [0001] The invention belongs to the field of welding, and in particular relates to a welding manufacturing method of a large-scale cast-welding structure hoop and cable clip. Background technique [0002] There are two types of cable clips for sports venues: ring cable clips and radial cable clips. Among them, the ring cable clip is the key component connecting the radial cable and the hoop cable. The component forces need to be balanced with each other, therefore, the quality of the ring rope clamp is particularly important. [0003] The existing ring cable clip adopts casting process as a whole, and the ring cable clip is composed of the main body, the strut ear plate formed on the front side of the body, the left cross lug plate and the right cross lug plate formed on the left and right sides of the strut ear plate 1. The left and right membrane cable ear plates formed on the left and right sides of the main body are integrally cast. The strut lugs are pe...

Problems solved by technology

In addition to common defects such as sand loss, sand sticking, air holes, and shrinkage cavities, the ring cable clips made of integral casting are prone to defects, and at the same time, due to the structure and process characteristics of the ring cable clips, sometimes there will be defects such as cold shut or mold filling. Insufficient and other typical casting defects, the casting rejection rate is extremely high, which greatly reduces the casting yield of the ring cable clamp, affects the casting quality and production schedule, and increases the casting cost
