Description

Technical Field

[0001] The invention relates to the field of detection facilities, in particular to a welding wire feeding detection device. Background Art

[0002] Welding wire is a metal wire material used as filler metal or as a conductor in the welding process. Some large-diameter welding wires need to be tested for wear resistance before being collected after processing to check whether the product is qualified.

[0003] However, in the actual detection process, when the welding wire is worn, powder will be produced. When this part of the powder adheres to the welding wire, it will increase the roughness of the welding wire surface. At the same time, the powder will also act as an abrasive, thereby increasing the wear force on the welding wire and accelerating the wear of the welding wire surface. Since the wear force during the detection is gradually increasing and not constant, the wear resistance test results are not accurate enough. Summary of the invention

[0015] 3. Through the provided pressure head, the welding wire can be pressed toward the V-shaped seat, so that the welding wire is bent and pressed in the V-shaped seat. At the same time, the No. 1 chuck presses the welding wire in the wire limit seat. Then the bridge continues to move down and presses on the pressure column, so that the pressure head and the No. 1 chuck can be firmly pressed on the welding wire. During this process, the bridge will drive the push frame to move, so as to drive the guide edge to slide on the L-shaped frame, so that the No. 2 chuck can be pushed obliquely to perform secondary compression on the bent welding wire to firmly fix the welding wire, thereby ensuring the wear strength of the grinding head on the welding wire, so as to avoid the displacement of the welding wire during the wear process, resulting in insufficient wear strength affecting the detection accuracy.
