Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of welding core production, in particular to a drawing device for producing alloy welding cores. Background Art
[0002] Electric welding is the common name for the arc welding rod. It is a welding operation achieved by using the welding rod to melt the metal parts to be connected at high temperatures through the arc. Electric welding is widely used in various fields. When the welding rod burns, the metal in the welding core melts and welds. However, the metal welding core needs to be drawn to make it thinner so that it can be easily ignited for welding. The traditional drawing method uses external force to apply to the front end of the drawn metal, pulling the metal billet out of a die hole smaller than the billet's cross-section to obtain the corresponding shape and size. The thin welding core is very easy to break during the drawing process using traditional drawing methods, resulting in material waste. To this end, we propose a drawing device for producing alloy welding core. Utility Model Content
