Cutting blade and manufacturing method thereof

Abstract

The invention provides a cutting blade and a manufacturing method thereof. Weight unbalance can be solved, burdens and mental stress of a worker are avoided, cutting work can obtain a good cutting face, and meanwhile, the long-term stable cutting function can be achieved. The cutting blade is characterized in that a circular-plate-shaped base body metal with a mounting hole in the central positionand blade fixing portions on the peripheral edge portion according to a certain interval and blade bodies fixed to the blade fixing portions of the base body metal are provided, and a method for arranging a certain-area opening and the like on the peripheral edge portion of the base body metal to adjust the weight unbalance according to the weight balance of the base body metal is provided. The opening is machined in a manner that the unbalance position and the deviation weight can be obtained on a balance measuring clamp under the vertical state in a manner of supporting the base body metalto freely rotate

Description

technical field [0001] The present invention relates to a blade mounted on the outer peripheral edge of a base metal, a cutting blade used for cutting wood and other materials to be cut, and a manufacturing method thereof. Background technique [0002] Conventionally, a cutting blade is a blade made of a cemented carbide alloy brazed and fixed to the outer peripheral edge portion of a disc-shaped base metal, as disclosed in Patent Document 1, for example. The cutting blade forms a plurality of knife chambers at certain intervals on the outer peripheral edge of the base metal, and at the same time, blade fixing parts are formed between the knife chambers, and the superhard alloy blades are respectively brazed and fixed on the blade fixing parts. As shown in Japanese Patent Application Laid-Open No. 2011-161819. [0003] However, in such cutting blades, the weight of the base metal may be unbalanced in the grinding and processing of the base metal, the grinding of the blade, ...

AI Technical Summary

Problems solved by technology

Also, when screen printing for finishing procedures, the weight of the ink may not be uniform across the surface of the base metal

[0004] Therefore, the weight of the manufactured cutting blade is likely to be unbalanced. When the cutting blade is installed on a cutting machine, for example, if the material to be cut is wood, the base metal will vibrate when rotating, and the vibration will be transmitted to the operator, which will increase the workload of the operator. and psychological pressure, and the cutting surface of the cut material is very rough due to vibration

In addition, the vibration acts on each cutting blade, which increases the burden on the blade itself during cutting, and the cutting edge (blade) of the cutting blade wears out quickly. At the same time, due to the vibration of the cutting blade, the main shaft of the cutting machine itself is also easily damaged.

Therefore, the cutting blade will increase the burden and psychological pressure of the operator due to vibration, and cannot ensure that the cutting operation can obtain a good cutting surface, and it is also difficult to obtain long-term stable cutting performance, etc.
