Description

Technical Field

[0001] The utility model relates to the field of sawing machines, in particular to a numerically controlled band sawing machine. Background Art

[0002] The sawing machine is a machine tool that uses circular saw blades, saw bands or saw blades as cutting tools to saw metal round materials, square materials, pipe materials and profiles. The processing accuracy of the sawing machine is generally not very high, and it is mostly used in the material preparation workshop to cut various rods, pipe materials and other profiles. The saw blade is driven by the driving wheel and the driven wheel, and the cutting direction of the saw blade is controlled by the guide rail control frame. The band saw blade is adjusted and straightened by adjusting the self-rotating bearing, and the sawing is swept away by the sweeper. The guide rail control frame is supported by the hydraulic cylinder piston rod to fall into the sawing material. The band saw machine is equipped with a manual or hydraulic cylinder clamping and locking mechanism, as well as a hydraulic operating valve switch.

[0003] In the prior art, when a CNC band saw is cutting metal parts, metal debris generated will fall onto the workbench. If not cleaned in time, during the long-term use of the CNC band saw, these metal debris will fall into the gap of the machine tool under the influence of the vibration force generated when the CNC band saw is running, causing blockage or damage to machine tool parts. Therefore, after the metal parts are cut, the metal debris on the workbench is generally cleaned by staff. However, since the metal debris dropped on the workbench is relatively scattered, it is troublesome to clean it manually, and manual cleaning is also time-consuming and labor-intensive, which brings inconvenience to the cleaning operation when cleaning the debris on the CNC band saw.
