Description

Technical Field

[0001] The utility model relates to metal wire processing equipment, in particular to metal wire straightening and cutting equipment. Background Art

[0002] Metal wires are generally produced in long strips and wound on a reel for easy transportation and sales. Customers then straighten and cut them into different sizes according to their own needs. The traditional method of straightening and cutting metal wires is to manually pull the metal wires on the reel to a size larger than the required size and then cut them off. Then, the two ends of the metal wires are twisted on a fixing device and a stretching device respectively, and the metal wires are straightened and then cut into sections with shears or a cutting machine. This processing method has high labor intensity and low production efficiency. In addition, since the twisted joints at both ends of the metal wires need to be cut before they can be used, it causes a waste of metal wire raw materials.

[0003] Therefore, the corresponding straightening and cutting machines are now used to replace traditional manual labor, which not only speeds up processing efficiency and reduces labor intensity, but also reduces the waste of raw materials. The existing straightening and cutting machine includes a guide tube, a straightening conveyor and a cutting machine arranged in sequence, and corresponding pressure wheel assemblies are respectively arranged between the guide tube and the straightening conveyor, and between the straightening conveyor and the cutting machine. The metal wire is guided into the straightening conveyor through the guide tube, and is pressed down and guided by the pressure wheel assemblies on both sides of the straightening conveyor, and then straightened and cut by the cutting machine. In order to ensure the straightening effect, it is necessary to first use the straightening conveyor for straightening and then use the cutting machine for cutting. However, in this way, not only does the equipment need to be set separately, the structure is relatively complex, and it occupies a large space.

[0004] Therefore, on the basis of ensuring the quality of metal wire stretching and cutting, the research purpose of the utility model is to design a metal wire straightening and cutting equipment with a simpler structure and more time-saving processing. Utility Model Content
