Description

Technical Field

[0001] The utility model relates to the technical field of steel wire straightening, in particular to a straightening device for preventing steel wires from falling off. Background Art

[0002] The wire adjustment device is to draw and compress the bent wire. Under a large pressure, the bent part of the wire is adjusted to a straight shape. During the feeding process, the direction of the wire can be ensured to be straight, and the quality of the wire can be ensured to meet the specified standards. There are various straightening devices on the market to prevent the wire from falling.

[0003] Comparative patent: A straightening device (authorized public number CN208483153U). This patent changes the straightening device from pure manual straightening to automatic straightening, which solves the problem of potential safety hazards when manually straightening steel wires. However, this device can only straighten a single size of steel wire and cannot adjust the spacing of the straightening device according to the size of the steel wire. The scope of use is relatively single and inconvenient. Therefore, those skilled in the art provide a straightening device that prevents steel wires from falling, which solves the problems raised in the above background technology.

[0004] However, the general straightening device is not convenient for preventing the steel wire from accidentally falling during the straightening process. It is inconvenient to use and it is not convenient to adjust the spacing of the straightening device according to the size of the steel wire. Other straightening devices may need to be used. The practicality is poor. It is also not convenient to automatically cut the straightened steel wire. Another cutting device may need to be used for cutting, which increases the steel wire processing time. Therefore, we propose a straightening device that prevents the steel wire from falling, so as to solve the above problems. Utility Model Content
