A stripping device for detecting the filling rate of flux-cored welding wire

Abstract

The invention discloses a stripping device for detecting filling rate of a flux-cored wire and a detection method. The stripping device comprises a gear A and a gear B, wherein the gear A and the gear B are mutually engaged and are fixedly arranged on a bracket through core shafts; a circular disc A is fixedly arranged on the gear A, and a groove is arranged on the circumference of the circular disc A; a circular disc B is fixedly arranged on a gear B, and a convex sharp corner is arranged on the circumference of the circular disc B and is matched with the groove; the flux-cored wire is put on the stripping device to strip, so as to obtain the filling rate of the flux-cored wire. The striping device has the advantages that the structure is simple, the production, processing and manufacturing are convenient, the peeling of metal is avoided in the stripping process for powder weight measuring, and the accurate and true filling rate of the flux-cored wire can be obtained.

Description

technical field [0001] The invention belongs to the field of metal wire production, and in particular relates to a peeling device for detecting the filling rate of flux-cored welding wire. Background technique [0002] The powder filling rate of flux cored wire is the key parameter of flux cored wire product quality. During the production process of flux cored wire, the forming machine first rolls the steel strip into a U-shaped groove, and then the powder adding mechanism evenly adds the powder into the U-shaped groove , and then rolled into O-shaped, the O-shaped metal wire is thinned to the diameter required by the product through a wire drawing machine. During the production process, it is necessary to check whether the filling rate of the drug powder in the wire is consistent with the theory. The traditional method is to cut several sections The wires of equal length are numbered and weighed to obtain the total weight. Then use two needle-nose pliers to twist the wire i...

[0002] The powder filling rate of flux cored wire is the key parameter of flux cored wire product quality. During the production process of flux cored wire, the forming machine first rolls the steel strip into a U-shaped groove, and then the powder adding mechanism evenly adds the powder into the U-shaped groove , and then rolled into O-shaped, the O-shaped metal wire is thinned to the diameter required by the product through a wire drawing machine. During the production process, it is necessary to check whether the filling rate of the drug powder in the wire is consistent with the theory. The traditional method is to cut several sections The wires of equal length are numbered and weighed to obtain the total weight. Then use two needle-nose pliers to twist the wire into a spiral shape, and then twist it into a spiral shape in the opposite direction. After the metal wire is spiraled forward and reverse, the O-shaped wire is If a small gap is enlarged, the powder in the wire can be completely poured out and weighed to measure the metal weight, and then the filling rate of the powder can be obtained. It is very troublesome to measure the powder weight in this way, and it is easy to cause metal peeling during the peeling process to affect the filling rate. sex

[0003] Existing wire stripping machines cannot be applied to flux cored wire stripping

In the published patent 201610527045.3, a scribe knife and a wire slot are used to peel off and separate the skin and metal wire of waste electric wires. When using it, one end of the wire needs to be clamped with pliers and pulled towards the other end. When the wire passes through the scribe knife It will cut the skin of the wire; this kind of device that clamps the wire and peels it with a sharp knife cannot be used in the detection of the filling rate of the flux cored wire. There is no separation, unless you turn around and peel it off again or manually peel it off with pliers; second, the diameter of the flux-cored welding wire is 1.2-1.6mm, and the diameter of the wire is generally more than 10mm. The diameters of the two are not of the same order of magnitude. The accuracy (including positioning accuracy and stripping accuracy) does not meet the requirements, so the wire stripping machine cannot be applied to flux cored wire stripping
