Mixed steel ball sizer

Abstract

A mixed steel ball sizer comprises a sizing plate and sizing grooves. A sizing opening is formed in the sizing plate, the width of the sizing opening is larger than diameters of steel balls to be sized, and the length of the sizing opening is smaller than or equal to the length of the mixed ball sizing plate. The sizing grooves are formed by splicing of a plurality of V-shaped grooves which are open upwards and are parallel, the ends of the V-shaped grooves are connected with the sizing opening of the sizing plate, and sieving holes are formed in the bottoms of the V-shaped grooves. The sizer has the advantages that the surfaces of the steel balls are not easy to damage, and the flow speed is fast.

Description

technical field [0001] The invention relates to a filter, in particular to a steel ball mixed ball filter. Background technique [0002] At present, domestic steel ball mixed ball screening equipment mainly includes ZD52S steel ball automatic screening machine, GX-756 and GX-540 steel ball sorting machines, etc. The design principle: the feed plate adopts a round hole sieve plate slightly larger than the steel ball specification , the large-sized mixed balls are blocked first, and the normal balls enter the gauge sorting tank through the round hole sieve plate, and the balls of different gauges are screened out from different outlets in order from large to small, and finally the small-sized balls flow out. The disadvantages are: [0003] 1. The screening efficiency is extremely low. Taking the ZD52S steel ball automatic screening machine as an example, although its precision can reach 0.002MM, it can only screen about 600 grains per minute at most. Taking the ball with a spe...

Problems solved by technology

[0003] 1. The screening efficiency is extremely low. Taking the ZD52S steel ball automatic screening machine as an example, although its precision can reach 0.002MM, it can only screen about 600 grains per minute at most. Taking the ball with a specification of 3.969MM as an example, a plate of balls is about 800,000 balls, it takes at least 20 hours to select a set of balls, which is too inefficient for a professional manufacturer of steel balls with an annual output of billions of balls equivalent to tens of thousands of plates, which requires the purchase of a large number of screening equipment and long-term continuous operation To keep up with the production tempo

[0004] 2. It is very easy to damage the surface quality of steel balls. The surface quality of high-precision steel balls is too high. From the beginning of feeding, the round hole sieve plate keeps rotating, and the friction between balls and balls and between balls and round holes is even caused by repeated collisions. Squeeze, it is very easy to cause scratches. When entering the gauge value sorting tank, due to the high precision, the steel balls are squeezed in the sorting tank. The friction is large, and it is easy to cause scratches
