Abstract
Description
Technical Field
[0001] This invention belongs to the field of fastener processing technology, specifically, it relates to a laser cutting machine for preparing fastener blanks. Background Technology
[0002] Fasteners, as core components of mechanical connections, are widely used in various equipment manufacturing fields, and their quality directly affects the stability and reliability of the entire machine structure. In the fastener production process, the dimensional accuracy and cut quality of the blank are crucial, determining not only the processing efficiency of subsequent cold heading and thread rolling processes, but also directly impacting the mechanical properties and assembly quality of the final product. Excessive dimensional deviations or defects such as burrs and cracks in the cut can easily lead to accelerated mold wear, misalignment, and even molding cracking during processing, thereby reducing product yield and affecting the connection strength and service life of the fasteners.
[0003] The existing equipment has the following drawbacks during use: First, it easily generates splatter and dust during the cutting process, which not only causes environmental pollution but also adheres to the surface of the blank and the optical components of the equipment, thus affecting the cutting accuracy and shortening the service life of the equipment. Second, fastener blanks are mostly cut from bars or plates. Under the high-speed operation of the existing laser cutting machine, the raw materials are prone to displacement, which leads to cutting deviations and affects the processing quality. At the same time, the existing equipment places the blank directly on the operating table, which may cause the laser to cut onto the surface of the operating table, thereby damaging the equipment.
