Steel ball quenching machine

Abstract

The invention relates to a quenching machine of a steel ball, which pertains to the technical field of quenching facilities of metal materials. The quenching machine of the steel ball comprises: a steel ball lifting mechanism which is used for conveying the rolling-formed steel balls; a ball-feeding mechanism which is used for accepting the steel balls conveyed by the steel ball lifting mechanism and is connected with the steel ball lifting mechanism; at least one set of steel ball spiral separating quenching mechanisms which are used for conducting a quenching treat to the steel balls fed by the ball-feeding mechanism and is connected with the ball-feeding mechanism; conveying mechanisms of quenching mediums which have the same quantity with the steel ball spiral separating quenching mechanisms and are used for providing the quenching mediums to the steel ball spiral separating quenching mechanisms and connected with the steel ball spiral separating quenching mechanisms. The invention has the advantages that: the steel balls can obtain inside and outside uniform quenching effects and the hardness (HRC) thereof can reach 60-70; the steel ball lifting mechanism, the ball-feeding mechanism, the steel ball spiral separating quenching mechanisms and the conveying mechanisms of the quenching mediums can be coordinated with each other, thus improving the quenching efficiency in unit time by more than 5 times than the prior art.

Description

technical field [0001] The invention relates to a steel ball quenching machine, which is used for rapidly cooling the rolled and formed steel balls in a quenching medium such as water and oil, so as to improve the strength, toughness and fatigue resistance of the steel balls. The physical properties of the invention belong to the technical field of quenching facilities for metal materials. Background technique [0002] Taking the building material production industry such as cement plant as an example, in the process of cement production, the ore needs to be ball milled (called grinding in the industry), and the ball mill needs to use a large number of steel balls with ideal wear resistance and high hardness. The more common quenching machine used in the prior art for quenching steel balls is shown in Figure 6. It is mainly composed of a cylinder 8 and a cylinder driving mechanism 9 arranged obliquely (one end is high and the other end is low). The two ends of the cylinder ...

AI Technical Summary

Problems solved by technology

In the process of use, due to the poor wear resistance and easy deformation of steel balls, the production industry will frequently replace steel balls, increase the cost of use, and affect normal production due to the low efficiency of ball milling due to deformation; in terms of quenching efficiency, If a large number of balls are continuously fed into the cylinder cavity of the cylinder body 8 through the ball feeding channel 83, the physical properties of the steel balls will be worse due to serious clustering; , and will cause inactive consumption of energy, because the cylinder 8 is passively in a state of being hungry and tending to run dry
