Abstract

The invention discloses a rear-arranged impunity removing device of a high speed steel wire production line. The device comprises a motor, a motor shaft is arranged below the motor, the tail end of the motor shaft is provided with a driving wheel, the driving wheel drives a driven wheel to rotate, a hollow rotation shaft is arranged below the driven wheel, a transmission shaft is arranged above the driven wheel, the other end of the transmission shaft is provided with a storage box, the tail end of the hollow rotation shaft is connected to a diverter, the tail end of the diverter is provided with a cover, and iron scrap suction apparatuses are arranged inside the diverter and the cover. The rear-arranged impunity removing device of the high speed steel wire production line has the advantages that the structure is reasonable, impunities can be removed comprehensively, the efficiency is higher, and the service life is longer.

Description

technical field [0001] The invention relates to the field of high-speed steel, in particular to a device for removing impurities behind a high-speed steel wire production line. Background technique [0002] High-speed steel wire is also known as wind steel or front steel, which means that it can be hardened even if it is cooled in air during quenching, and it is very sharp. It is a complex alloy steel containing carbide forming elements such as tungsten, molybdenum, chromium and vanadium. The total amount of alloying elements is about 10-25%. It can still maintain high hardness under the condition of high heat generated by high-speed cutting (about 500°C), and its HRC can be above 60. This is the most important characteristic of high-speed steel - red hardness. After quenching and low-temperature tempering, carbon tool steel has high hardness at room temperature, but when the temperature is higher than 200°C, the hardness drops sharply, and the hardness has dropped to a l...
