[0002] A sawing machine is a device used to process metal materials. It is generally suitable for cutting various metal materials such as alloy steel and stainless steel through the internal saw blade. Generally, the cutting is achieved by placing the workpiece under the saw blade and driving the saw blade to move.

[0003] In most existing sawing machines, cutting metal will result in a lot of metal debris. The accumulation of these debris can easily cause the user to touch the workpiece and remain on the clothes or even the skin. Since the iron chips are very small and sharp, it is easy to cause scratches on the operator. Therefore, a band saw machine that can clean the iron chips is needed.

[0004] The invention patent "A cleaning device for a metal band saw" with the authorization announcement number CN117139729B proposes a band saw that can clean the saw blade. However, the iron filings will not only remain on the saw blade, but also leave a lot of fine chips on the saw. If they are not cleaned in time, users will still touch them by mistake. In addition, due to the small size of the iron filings, during the cleaning process, they will fan and cause the iron filings to fly, which will be more difficult to handle. Summary of the invention

DETAILED DESCRIPTION

[0028] The technical solutions in the embodiments of the present invention are described clearly and completely below. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] Embodiment 1

[0030] See also Figure 1 , Figure 2 and Figure 7 This embodiment provides a CNC high-speed band saw, including a base 11 and a workbench 12 installed on the base 11, and the workbench 12 is provided with a saw blade assembly 14 for cutting and a first moving assembly 2 for feeding a workpiece to be processed.

[0031] The saw blade assembly 14 includes a protective shell 143, in which a driving wheel 142-1 and a tensioning wheel 142 are rotatably connected, a saw blade 141 is installed between the driving wheel 142-1 and the tensioning wheel 142, and a moving groove for moving the tensioning wheel 142 is provided on the protective shell 143 behind the tensioning wheel 142.

[0032] The tensioning wheel 142 in the saw blade assembly 14 can be moved in a movable groove by installing a motor for driving movement at the rear to adjust the tensioning state. When rotating, the saw blade 141 can be driven to cut the workpiece through the driving wheel 142-1 and the tensioning wheel 142. A motor for driving the driving wheel 142-1 to rotate is installed at the rear of the saw blade assembly 14.

[0033] A rear shell 16 is installed at the rear of the workbench 12, and the first moving assembly 2 includes a moving frame 222 slidably connected to the workbench 12 and the rear shell 16, and a plurality of rotating rollers 221 are installed on the rear shell 16. A supporting tray 24 is fixedly connected to the moving frame 222, and the workbench 12 is provided with a second guide rail 223 for driving the supporting tray 24 to move along the width direction of the workbench 12.

[0034] The second guide rail 223 can drive the support tray 24 to move and drive the workpiece to be fed forward. The plurality of rotating rollers 221 can also help reduce friction when the workpiece moves forward. At the same time, when the rotating rollers 221 are equipped with a motor to work, the workpiece can be automatically fed forward.

[0035] The tray 24 is fixedly connected to a fixing block 232 , and the tray 24 is also provided with a third clamping block 231 that moves toward or away from the fixing block 232 . The workbench 12 is provided with a hydraulic telescopic rod 23 for driving the third clamping block 231 to move.

[0036] During the feeding process of the tray 24, the workpiece needs to be clamped. After the workpiece is stably placed on the tray 24, the hydraulic telescopic rod 23 is extended to drive the third clamping block 231 to push the workpiece to the fixed block 232 to achieve clamping.

[0037] After the clamping is completed, the support tray 24 can be driven forward by the second guide rail to adjust the position of the workpiece to be directly below the saw blade assembly 14 .

A telescopic bracket 25 for supporting the saw blade assembly 14 is fixedly connected to the workbench 12.

[0042] Through the servo electric cylinder 18, after completing a cut, the saw blade assembly 14 can be raised or lowered through the electric telescopic rod 17 to achieve the feeding of the saw blade 141 in the height direction. Through the auxiliary telescopic rod 20 and the telescopic bracket 25, the protective shell 143 is supported to prevent the electric telescopic rod 17 from being subjected to too much pressure.
