Background

The double-lug wedge-shaped wire clamp is a cable clamping part of a catenary, a contact wire and a stay wire on a contact network of the electrified railway at the joint of a terminal and a lower anchor. As shown in fig. 1. The reliability of the connection anchoring of the connecting device directly influences the safe operation of the contact network. Wherein: 1 is a thread, 3 is a double-lug wedge-shaped wire clamp body, 2 is a wedge, 6 is a connecting hole, and the wire clamp is of an integral casting structure as shown in figure 1. The cast steel casting process can not completely ensure that the cast has no defects of air holes, cracks, inclusions and the like, and the cast needs to be subjected to radiographic inspection piece by piece, so that the percent of pass of the cast is only 65%. The production efficiency and the qualification rate are low. Due to the complex structure of the workpiece, all casting defects are not easy to be discharged by 100% when flaw detection grading is carried out, and hidden troubles are buried for safe and reliable operation of work.
