Manufacturing device and manufacturing method of ball mill steel ball

Abstract

The invention relates to a manufacturing device and a manufacturing method of a ball mill steel ball. The device comprises a forging machine and a quenching device, and further comprises a feeing pipe, wherein the inner part and / or the outer part of the feeding pipe are / is provided with insulating layers / an insulating layer; an inlet of the feeding pipe is connected with a discharge end of the forging machine; an outlet of the feeding pipe is connected with a feeding end of the quenching device; and the inlet of the feeding pipe is positioned above the outlet of the feeding pipe. When the device is adopted for manufacturing the steel ball, during the two procedures of steel ball forging and quenching, the steel ball is subjected to tempering treatment during the high-temperature steel ball transportation process in the feeding pipe; on one hand, the steel ball can be prevented from being influenced by external airflow, and the temperature uniformity before steel ball quenching is improved; and on the other hand, the lattice imperfection and internal stress generated during steel ball forging can be eliminated, after the steel ball is subjected to follow-up quenching, the performance of the steel ball is obviously improved, the product uniformity is good, and the continuous production is not influenced.

Description

technical field [0001] The invention relates to manufacturing equipment and a manufacturing method of ball mill steel balls. Background technique [0002] The ball mill is a commonly used material crushing equipment. Its basic structure is that a large number of steel balls are stored in a cylinder. When the ball mill is working, the material is put into the cylinder, and the driving mechanism drives the cylinder to rotate. The steel balls and materials inside the cylinder continue to roll and throw, and the steel balls continuously form a knocking effect on the material to make the material pulverized. In addition, when the material tumbles in the cylinder, it also has the effect of surface grinding. [0003] Based on the working principle of the ball mill, the steel ball has to bear the impact of collision and wear and tear continuously, which requires the steel ball to have sufficient strength and toughness, otherwise the steel ball will be broken or the surface will wea...

Problems solved by technology

[0006] However, since each steel billet may have individual differences when it is heated and forged, it is difficult for each steel ball to reach a completely consistent temperature when it is output from the forging machine, and the high-temperature steel ball is easily affected by the external air temperature during the process of sliding from the V-shaped groove. Affected, the temperature difference becomes larger when the steel ball reaches the quenching pool, and the performance consistency of the final product after quenching is poor
