Heat treatment quenching apparatus used for steel ball with minor diameter

Abstract

The invention relates to a heat treatment quenching apparatus used for a steel ball with minor diameter, which comprises a pool, a rotating disk, a cold water supply pipe, a speed regulation motor, and a steel ball supply long groove and a steel ball recovery long groove, a rotating shaft is fixed at the center of the rotating disk, the rotating shaft crosses over the rotating shaft, thereby the bottom half of the rotating disk is placed in the pool, a plurality of container-like cavities which are opened inwards used for accommodating steel balls are circumferentially and uniformly arranged along the outer edge of the rotating disk, the steel ball supply long groove stretches into one cavity at one side of the bottom half of the rotating disk and supplies the steel ball, the steel ball recovery long groove extends to one cavity at other side of the top half of the rotating disk and is used for carrying the steel ball after quenching; the cold water supply pipe is the spray pipe which is placed in the pool, and the bottom half of the rotating disk supplies cold water, and the setting of a spiracle on the spray pipe is gradual decrease from a water inputting end. The heat treatment quenching apparatus aims at the quenching apparatus used for forging steel ball with diameter between 20-30 millimeters, and can satisfy large-batch quenching requirement.

Description

technical field [0001] The proposal relates to the technical field of steel ball quenching, specifically a heat treatment quenching device for small-diameter steel balls (diameter between 20 and 30 mm). Background technique [0002] Forged steel balls are widely used in electric power, coal, metallurgy, mineral processing, construction cement and chemical industries. Improving the internal quality of the steel balls is of practical significance to reduce costs and increase income for customer manufacturers. [0003] Traditional steel ball quenching equipment generally adopts rolling water quenching, spiral quenching and other methods, which can easily cause steel balls to contact each other during rolling, and cause uneven hardness of steel balls due to friction, which affects product quality. Based on this, for small-diameter cross-rolled steel balls below 30 mm, the applicant adopted a process in which the rolled steel balls enter the turntable with buffer water and then q...
