Welding manufacturing method for large cast-weld structure ring cable clamp

Abstract

The invention discloses a welding manufacturing method for a large cast-weld structure ring cable clamp. According to the method, welding materials and a welding method which are matched with a cableclamp body and a lug plate are adopted, pre-welding preheating temperature and interlayer temperature are controlled, proper welding process parameters are selected, a crossed cable lug plate, a membrane cable lug plate and a supporting rod lug plate are welded to the ring cable clamp body, so that the mechanical property of welded joints is guaranteed, and meanwhile, the production efficiency isgreatly improved, and the manufacturing time is saved; measures such as groove design and welding sequence control are adopted, so that the manufacturing mounting precision of the ring cable clamp welded joints is guaranteed, and the welding deformation is reduced; and the post-welding overall stress relief annealing treatment method is adopted, so that the internal stress of the weld joints and the internal stress of the whole cable clamp are reduced.

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
