Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of cutting machine tools, in particular to a cutting machine tool for metal wire processing. BACKGROUND

[0002] In the field of metal wire processing, the initial form is mostly a long strip of raw material in the form of a roll or a fixed length. However, the downstream applications such as mechanical manufacturing, electronic components, automobile parts, hardware tools, etc. have specific and diverse requirements for the length and size of the metal wire. For example, the wire segments for making bolts, metal pins for electronic connectors, and wire blanks before spring processing, etc. require the original long strip of hard metal wire to be cut into short segments that meet the specifications of subsequent processes or products to facilitate subsequent processing and use.

[0003] The existing cutting machine tool for metal wire does not have a cutting and conveying cooperative stop function. Specifically, when the device performs a cutting action, the metal wire conveying system will still maintain a continuous conveying state, and the upper and lower cutting tools in the cutting machine tool are always in a fixed action position during the cutting process. This fixed position directly blocks the metal wire being conveyed. To avoid the blockage of the cutting tool and continue conveying the wire, the metal wire and the conveying roller will experience severe friction and slippage due to unbalanced force. Long-term use not only causes surface wear and scratches on the wire, but also may cause wear on the surface texture of the conveying roller, thereby reducing the conveying accuracy. In severe cases, it may even cause deformation of the wire or failure of the conveying roller, affecting the overall processing efficiency and product quality, and having poor stability and low practicality.
