Description

Circular saw blade cutter

This creation is about a circular saw blade cutting machine for grinding the blade of a circular saw blade to cut the blade.

According to the groove around the circumference of the circular saw blade, the circular saw blade is mainly placed on the fixture of the cutting machine, and the circular saw blade is rotated by the diverging machine to rotate the circular saw blade to the circular saw. The periphery of the sheet is cut to produce a plurality of grooves equidistantly on the circumference.

However, the conventional dissection machine uses a cylinder as a power to change the position of the grinding wheel to perform the groove cutting process on the circular saw blade. However, the gas of the cylinder often contains water, so it is easy to cause the life of the circular saw blade. The problem of rust, at the same time, the cylinder is also easy to wear under long-term use, and the use of the cylinder needs to be matched with many sensors and the like, which makes the cost of the trenching machine high and the inconvenience of maintenance.

In order to solve the above problems, the present invention discloses a circular saw blade cutting machine which uses a drive shaft to drive three cams to push the circular saw blade and feed the wheel to both sides of the circular saw blade. The action of the knife and the traverse can achieve smooth operation.
