Description

Technical Field

[0001] The utility model relates to the technical field of protection structures, in particular to a protection structure for a saw belt of a numerically controlled 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] As disclosed in the authorization announcement number CN220480422U, a saw band protection structure for a CNC sawing machine is disclosed, which belongs to the field of saw band protection fences. A saw band protection structure for a CNC sawing machine comprises a group of L-shaped mounting strips, a cross bar is arranged between the group of L-shaped mounting strips, and blocking rods are slidably connected inside the sliding holes. The saw band protection structure is installed on the outer side of the saw band of the CNC sawing machine body, so that a layer of blocking guardrail structure is formed on the outer side of the saw band. When the saw band breaks, one end of the saw band that flies out or deviates can be blocked by a plurality of blocking rods to avoid flying out or deviating and injuring the staff, thereby improving the safety of the saw band of the CNC sawing machine body when cutting metal materials. However, during use, the protection effect is poor, it is difficult to install and has a small scope of application. For this reason, we propose a saw band protection structure for a CNC sawing machine to solve the problems of poor protection effect, difficulty in installation and small scope of application of traditional devices.
