Document Type and Number:
WIPO Patent Application WO/2020/076085
Kind Code:
A1
Abstract:
The present invention provides an excavator bucket tooth molding device, a method for manufacturing an excavator bucket tooth by using same, and an excavator bucket tooth manufactured thereby, wherein a superhard coating layer is formed on the surface of a tooth point, which is susceptible to wear, such that the resulting surface hardening improves anti-wear and anti-impact characteristics. In addition, the present invention provides an excavator bucket tooth molding device, a method for manufacturing an excavator bucket tooth by using same, and an excavator bucket tooth manufactured thereby, wherein a superhard coating layer is formed integrally with a tooth point such that the superhard coating layer does not detach, even when subjected to strong forces and wear actions, and thus can have a long life.
