[0002] Steel ball is an important basic component, which is widely used in bearings, hardware, electronics, metallurgy and other fields. The manufacture of steel balls is usually formed by casting, forging, grinding and other processes. The casting cost of small steel balls is high, and stamping is generally used. , in the process of processing, the metallographic structure of the steel ball is easily damaged, and the fiber is easily torn, resulting in cracking of the steel ball, resulting in a low yield of the steel ball and a short service life, and it is easy to affect the machine due to the problem of the steel ball equipment operation

The invention relates to the technical field of steel ball casting and particularly relates to a die-free steel ball casting device. The die-free steel ball casting device comprises a heat-preservation furnace, wherein a fixed first round disc, a rotatable rotary table and a fixed second round disc, which are arranged in sequence from top to bottom, are arranged under the heat-preservation furnace; a first round hole, a second round hole and third round holes are formed in the first round disc, the second round disc and the rotary table respectively; more than two third round holes are formed along the peripheral direction of the edge of the rotary table at intervals; a lower-end outlet of the heat-preservation furnace is aligned to the first round hole; a straight pipe is vertically arranged under the second round hole; and a rolling rail of a steel ball is arranged at a lower-end pipe opening of the straight pipe and a steam inlet is formed in the lower part of the straight pipe. When the die-free steel ball casting device is used, liquid steel sequentially flows into the first round hole, the third round holes and the second round hole from the lower-end outlet of the heat-preservation furnace, then falls into the straight pipe and is condensed to form the steel ball; the whole device has a simple structure and the casting cost of the steel ball is relatively low; and the machined steel ball has a complete metallographic structure and the steel ball has relatively good quality and relatively long service life.
