Drum device for online continuous quenching of inclined rolled steel balls

Abstract

The invention discloses a drum device for online continuous quenching of inclined rolled steel balls. The drum device comprises a water tank, a variable frequency control motor, a speed reducer, a chain wheel mechanism, a ball inlet chute, a conical ball inlet drum, a columnar quenching drum, a conical ball outlet drum, a ball outlet chute, a chute bracket, a bearing base, a rotating shaft and a four-jaw spoke; the conical ball inlet drum is used for smoothly leading large-diameter steel balls, introduced by the ball inlet chute, into the columnar quenching drum; the columnar quenching drum is used for realizing spiral feeding and quenching functions of the steel balls; and the conical ball outlet drum is driven by the rotating shaft to rotate to realize the purposes of fishing the quenched steel balls and pouring the steel balls in the ball outlet chute. The drum device has the following beneficial effects: for the steel balls, with diameters of 50-65 mm, molded through high-temperature inclined rolling, the online continuous quenching is performed, so that the energy is saved, the quenching time is precisely controlled, and the quality of the steel balls is improved; and the drum device is high in quenching efficiency, stable in process, low in noise and high in automation degree, and can satisfy the large-batch continuous quenching requirement of the steel balls.

Description

technical field [0001] The invention belongs to the technical field of metal manufacturing and its automation equipment, and in particular relates to a drum-type device for on-line continuous quenching of cross-rolled steel balls. Background technique [0002] The manufacturing methods of steel balls mainly include cold heading, hot heading, casting, rolling and other processes. The cross-rolled steel ball has the advantages of high production efficiency and material saving, and is suitable for large-scale batch production. A large number of steel balls after rolling need to be quenched to improve the hardness and wear resistance of the steel balls. Traditional steel ball quenching devices often have shortcomings such as poor ball discharge, uneven quenching, low efficiency, and large impact noise. Contents of the invention [0003] The object of the present invention is to overcome the shortcomings and deficiencies of the prior art, and provide a drum-type device for onl...
