Title:
MANUFACTURE OF BLADE OF HAND SAW
Document Type and Number:
Japanese Patent JP3944800
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To manufacture a saw blade of a hand saw having the uniform thickness and no distortion at low cost by decreasing the material cost through a process of enabling continuos polishing of a hardened steel strip and decreasing the polishing amount in the polishing process, and by decreasing the manufacturing cost through a process of improving the manufacturing efficiency.
SOLUTION: A manufacturing method of a saw blade of a hand saw is composed of a first process for applying tooth setting by forming a tooth forming body 2c on the edge of a hardened steel strip M into a tooth set steel strip 1a; a second process for continuously arranging respective rotational grinning wheels so fixed as to pinch the tooth set steel strip 1a and as to face a head in the transferring direction so as to symmetrically polish both surfaces of the tooth set steel strip 1a, polishing only the body parts of both side surfaces of the both set steel strip 1a in the set secured state, eliminating cut part, and for forming a polished steel strip 1b; a third process for forming a saw tooth part 2 on the saw tooth forming part 2c into a saw tooth provided steel strip 1c; and a fourth process for manufacturing a saw blade 1 by punching the saw tooth provided steel strip 1c into the saw blade shape.
