The submerged arc welding wire has many diameter specifications, and packaging specifications (width, inner diameter, outer diameter of different welding wire spools), which raises higher requirements to wire winding facilities. The design and manufacture of submerged arc welding wire winding machines encounter difficulties as follows: 1. Welding wire straightening difficulty: The welding wires have large ranges in diameters and specifications, the min. diameter of the welding wires used in submerged are welding is φ1.6, the max. diameter is φ6.4 (the actual winding scopes of our winding facilities are larger). Before rewinding welding wires must be straightened firstly, Straightener have two or three specifications suitable to rewind. The thinner the linear diameter of the welding wires, the smaller the diameter of the killing roller, and the smaller the center-to-center spacing of the straightening rollers. or vice versa. Therefore different, straightener must be used to straightening welding wires. 2. Inconsistency of welding wire spool standards The welding wires have various specifications, and the welding facilities used in actual manufacturing processes also have different types and have non uniform standards, these cause great difficulty in designing and manufacturing facilities. The way to operate by machines to make the arranging wires has many transmission ratios, when the winding width varies, its hard to be operated by machines, at this time, electric drive is required. 3. Welding wire layer winding difficulty Due to the bigger diameters of the submerged are welding wires, its difficult to arranging by hand when displacing the bottom layer of welding wires. In order to ensure arranging the bottom wire layer smoothly, slots will be grooved at the bottom of wire bush. one type of welding wire has a wire bush, but the manufacture of the wire bush is complicated and costly, equipping with more wire bush is therefore a hard problem. 4. Vairous customers requirements The requirements of users about winding efficiency are distinct, some of the users of the wire rewinding machine are also users of the welding wires, they have few requirements of winding efficiency, and the welding wire factories in small scale also have few requirements, but special manufactures of the submerged are welding wires require high winding efficiency.
