Abstract
The utility model relates to a CO2 gas shielded welding wire conveying pipe. In the welding wire conveying pipe, a fin spring steel wire is wound into a spiral wire feeding hose to be inserted into a nylon hose which replaces a multi-strand fin spring steel wire reinforced layer. Both ends of the nylon hose are screwed with locking terminals, one end of the locking terminal is provided with a thread hole, and the rear end is provided with a taper hole. The welding wire conveying pipe has favorable stiffness and elastic property, and a welding wire penetrates through the welding wire conveying pipe smoothly in uniform speed. The utility model has the advantages of high quality, low cost, long service life, easy fabrication, convenient maintenance, spring steel wire saving, and easy assembly.
Description
The utility model relates to a kind of CO
2The welding wire for gas shielded welding carrier pipe.
CO at home and abroad at present
2In the welding wire for gas shielded welding sender structure; the welding wire carrier pipe generally is to turn to helical Bourdon tube as wire convey soft pipe with 65Mn steel or stainless steel filament, and constitutes with multiply hairspring steel wire coiling one back-up coat on this wire convey soft pipe external diameter.This welding wire carrier pipe is owing to adopted the back-up coat of multiply hairspring steel wire coiling, there is following shortcoming: winding multi-strand hairspring steel wire back-up coat complex process, yield rate is lower, the material cost height, and service life is short; In the welding process, the welding wire carrier pipe constantly turns over and turns round, and the back-up coat some places of multiply hairspring steel wire coiling are loosening, and the some places distortion causes the wire feed difficulty; Corrosion and dust are easy to enter in the wire convey soft pipe by multiply hairspring steel wire slit, have increased wire-feeder resistance, make welding wire can not pass through the welding wire carrier pipe at the uniform velocity reposefully; Corrosion and contamination by dust the welding wire clean Surface; Its result has influenced weldquality in sum, has reduced the weld seam mechanical performance.In this external welding process, can not make things convenient for, flexibly, the weld seam to various diverse locations welds freely by the welding gun of welder operation.
The purpose of this utility model is to overcome above-mentioned weak point of the prior art and provides a kind of is the welding wire carrier pipe of back-up coat with the nylon sleeve.
The technical solution of the utility model is a spiral wire feed flexible pipe that turns to the spring finer wire to be inserted reinforce in the sleeve pipe, and reinforcing the sleeve pipe two ends locking terminal of screwing on respectively, its characteristics are that described reinforcing sleeve pipe is a nylon hose, and locking terminal front end is that screwed hole, rear end are taper hole.
This welding wire carrier pipe has good deflection and elasticity, welding wire is little by welding wire carrier pipe frictional resistance, wire feed is at the uniform velocity steady, dustproof anti-corrosion has improved welding quality, and every root bead silk carrier pipe was brought up to more than 2 years by original 3 months service life, save a large amount of spring steel wires, reduced cost, the manufacturing of this welding wire carrier pipe is simple, assembling is easy, easy to maintenance.
Fig. 1 is welding wire pipe structure figure.
Now in conjunction with the accompanying drawings big utility model is described further.
With reference to Fig. 1, with a diameter is that to turn to internal diameter be that 3 millimeters long are 4 meters spiral wire feed flexible pipe (5) for 1.2 millimeters 65Mn steel filament, be inserted into the internal diameter that replaces multiply hairspring, steel wire back-up coat and be 6 mm outer diameter and be in 8 millimeters the nylon hose (3), and the front end of screwing on respectively at the two ends of nylon hose (3) is that M8 screwed hole, rear end are the locking terminal (2) (4) of the taper hole of 1: 20 tapering.With reference to Fig. 1, when the locking terminal of screwing on, the screw thread of front end M8 screwed hole is squeezed into screw thread to nylon hose, and 1: 20 tapering taper hole of terminal rear end is with nylon hose (3) and wire convey soft pipe (5) locking.Welding wire (1) moves in spiral wire feed flexible pipe (5) at the uniform velocity stably.
