Abstract

The invention discloses an on-line eddy current testing device of multiple strands of tire cord steel wires, which comprises a roller support, rollers, a fixed support and a plurality of eddy currenttesting units, the rollers comprise a first roller and a second roller, and the first roller and the second roller are arranged on the two sides of the roller support respectively; the fixed support is arranged between the first roller and the second roller; each eddy current detection unit is arranged on the fixed support in parallel, and each eddy current detection unit detects one strand of tire cord steel wire. The eddy current testing units are installed side by side, the idler wheels serve as a conveying mechanism of the tire cord steel wires, online eddy current testing of the multiplestrands of tire cord steel wires is achieved, and the quality safety of the tire cord steel wires is guaranteed.

Description

technical field [0001] The invention belongs to the field of non-destructive flaw detection of tire cord steel wires, and in particular relates to an online eddy current detection device for defects of multi-strand tire cord steel wires. Background technique [0002] Tire cord steel wire is an important part of automobile tires, and its quality determines the impact resistance and safety performance of the tire. Therefore, it is of great significance to test and control the product quality of tire cord steel wire to ensure the safety of tires. [0003] During the tire cord production process, multiple strands of steel wires are drawn at the same time, and the distance between the steel wires is about 20mm. The steel wires also move radially while moving along the length direction. It is extremely difficult to perform eddy current testing on multiple strands of steel wires at the same time. The market lacks effective detection devices. Contents of the invention [0004] Ba...
