Diamond circular saw blade with nock-type tool bits

Abstract

The invention provides a diamond circular saw blade with nock-type tool bits and belongs to a processing tool. The diamond circular saw blade with the nock-type tool bits is formed by a matrix and the tool bits. The tool bits are of a nock shape and are formed in a mode that >-shaped blocks are alternately connected in a concave-convex mode along the same direction. The direction of the >-shaped blocks is the rotating direction. Water tanks on the matrix are deflected towards the direction of the >-shaped blocks and are respectively at an included angle of 20 to 30 degrees with the longitudinal direction. The bottom parts of the water tanks are in circular arc transition. When the tool bits are connected with the matrix, the odd number of the >-shaped blocks and the even number of the >-shaped blocks in the same direction are arranged alternately. When rotating at high speed, the saw blade has a good cooling effect and is easy to discharge chips. Due to the existence of grooves, the resistance of the saw blade is reduced, the sharpness of the saw blade is obviously improved, and the diamond circular saw blade with the nock-type tool bits is widely suitable for the industries of stone processing and the like.

Description

technical field [0001] The invention relates to a cutting tool, in particular to a circular saw blade made of diamond. Background technique [0002] The existing diamond circular saw blade is composed of a steel substrate and sawtooth (commonly known as cutter head) embedded in the substrate. Function, the saw blade rotates at high speed during use. Ordinary saw blades have a thick head, high resistance, and the head is easily broken, and because of the high resistance, the force acting on the substrate is correspondingly large, so the bottom of the sink of the substrate is particularly easy to crack, which seriously affects the performance of the saw blade. High-speed rotation The cutter head is easy to be thrown out and cause work-related accidents. The chip removal in the existing diamond circular saw blade sink is not smooth, and the chips generated when cutting the object cannot be discharged in time, which accelerates the wear of the substrate, so that the wear of the...

Ordinary saw blades have a thick head, high resistance, and the head is easily broken, and because of the high resistance, the force acting on the substrate is correspondingly large, so the bottom of the sink of the substrate is particularly easy to crack, which seriously affects the performance of the saw blade. High-speed rotation The cutter head is easy to be thrown out and cause work-related accidents. The chip removal in the existing diamond circular saw blade sink is not smooth, and the chips generated when cutting the object cannot be discharged in time, which accelerates the wear of the substrate, so that the wear of the substrate and the teeth cannot be synchronized. , resulting in a waste of resources
