Description

TECHNICAL FIELD

[0001] The utility model relates to saw blade processing technical field, concretely is a saw blade piece surface sand blasting treatment device. BACKGROUND

[0002] During the sandblasting process of the saw blade, the direction of sandblasting and the placement direction of the saw blade need to be accurately controlled to ensure good sandblasting effect. The nozzle of the sandblasting machine should usually be perpendicular to the surface of the saw blade, which can ensure that the sandblasting medium uniformly covers the surface of the saw blade, especially the tooth part and the outer edge of the saw blade. In some cases, the nozzle can be slightly inclined by about 15 to 30 degrees to avoid directly facing the reserved hole and other sensitive areas. This way can help protect these areas from being invaded by the sandblasting medium while still being able to effectively process the surface of the saw blade.

[0003] The protection device for saw blade sandblasting treatment disclosed in publication No. CN202220670308.7 includes first and second protection plates that are oppositely arranged in the sandblasting machine and have the same structure, are used to clamp the saw blade in the middle to protect the saw blade base so that only the tooth end surface is exposed, and have through holes in the centers and rubber sleeves on the edges. The first protection plate is connected with a rotating drive mechanism for driving the first protection plate to rotate, and an installation rod for installing the saw blade is arranged in the through hole of the first protection plate. The second protection plate is connected with a moving and rotating drive mechanism for driving the second protection plate to rotate synchronously with the first protection plate and move away from and close to the first protection plate.
