Description
Technical Field
The utility model relates to a welding equipment technical field, concretely relates to can be used to different diameter submerged arc welding wire's contact tip.
Background
The contact tip is an indispensable key part in submerged arc welding, and the quality of the performance of the contact tip is related to the welding quality. Submerged arc welding is a method of welding by burning an electric arc under a flux layer using the electric arc as a welding heat source. When welding, two stages of a welding power supply are respectively connected to the contact tip and the workpiece, the welding wire is contacted with the workpiece through the contact tip, the welding flux is scattered around the welding wire, then the power supply is switched on, and current flows through the contact tip, the welding wire and the workpiece to form a welding loop. During welding, the wire feeding mechanism continuously conveys the welding wire to the molten pool through the contact tip, and the welding wire, the workpiece and the welding flux are melted by the heat of the electric arc, so that the welding is realized. With the continuous progress of welding process, the welding wire is constantly carried to the molten bath by the contact tube, and the hole wall of welding wire and contact tube hole is constantly rubbed at this in-process, and the continuous grow of contact tube hole leads to the welding to send the accurate nature of silk to descend, and then influences the welding seam quality. Therefore, in order to ensure the welding quality, the contact tip needs to be replaced periodically. In addition, in the ship building process, a welder needs to select a proper welding process according to the met working conditions, and different welding wire diameters are suitable for the thicknesses of the corresponding steel plates. Before welding, a welder reselects an applicable contact tip according to the diameters of different welding wires, and detaches and replaces the original contact tip. Frequent replacement of the contact tip will seriously affect the welding efficiency and reduce the shipbuilding speed. The time for each cycle of ship construction is valuable, and delay of any one cycle can cause that the ship can not be delivered on time.
Disclosure of Invention
In order to solve the technical problem, the utility model provides a can be used to different diameter submerged arc welding wire's contact tip, the technical purpose of the utility model is realized through following technical scheme:

Furthermore, the slot extends from the outlet end to the connecting end, and the distance from the bottom of the slot to the thread of the connecting end is 2-5 mm.
Furthermore, the number of the slots is 3-5, the number of the openings is small, the elasticity is not large enough, the welding wire is prevented from passing through the welding wire channel, and the number of the openings is too large, so that poor contact between the welding wire channel and the welding wire is caused.
Further, the width of the slot is 0.75-1.25 mm.
Further, the width of the slot is preferably 1 mm.
Furthermore, the diameter of the welding wire channel at the end of the outlet end is 3mm, the diameter of the welding wire channel is 3mm when the contact tip is not provided with the welding wire, and the welding wire channel expands and opens under the action of the welding wire due to the elasticity of the welding wire channel, so that the welding wire channel is suitable for the welding wire with the diameter of 3-6mm, and meanwhile, the welding wire channel is ensured.
Furthermore, the outer wall of the outlet end is also provided with a hoop which is arranged at the bottom of the outlet end, and the welding wire channel can be abraded after the contact tip is used for a period of time, so that the size of the welding wire channel can be adjusted through the hoop, and the conductivity of the contact tip during welding is ensured.
The utility model has the advantages that, by the contact tip of the utility model, on one hand, the elasticity of the welding wire channel is ensured by slotting, thereby meeting the use of the welding wires with different sizes, avoiding the frequent replacement of the contact tips with different sizes, and ensuring the good contact between the welding wire channel and the welding wires; on the other hand, the ferrule is arranged on the outer wall of the outlet end, so that the problem of poor contact caused by abrasion of a welding wire channel in the long-term use process of the contact tip can be solved.
