Abstract

The invention relates to a manufacturing method for a bearing ball. The manufacturing method comprises the following steps of 1) selecting materials: selecting the materials and rough machining by upsetting and forging; 2) putting the materials into a 300 ton presser and hot forging at a temperature of 1,000-1,200 DEG C; 3) carrying out annealing treatment by using an oxygen-free annealing furnace at a temperature of 850-890 DEG C, keeping the temperature for 3-6 h and cooling; 4) carrying out cold rolling treatment after cooling and then quenching in a quenching furnace at a temperature of 100-200 DEG C; 5) melting the materials in a melting furnace and making melt liquid into a plurality of small cast ingots; and 6) putting the cast ingots in a grinding machine and grinding the cast ingots into balls. The balls manufactured by the method are good is quality and long in service life, and can effectively guarantee operations of machine equipment.

Description

A kind of making method of bearing ball

Technical field

The invention belongs to mechanical field, particularly a kind of making method of bearing ball.

Background technique

Bearing ball is a kind of very important rolling member, once deform or cracked, can cause the part of equipment to run improperly, even stall, cause the potential safety hazard in production, thus its quality and life-span be very important, in prior art, the technological process of normal application is: the process of forging, hot rolling, cooling, forging, annealing, tempering and grinding, but its complex process, causes slightly careless omission just to produce the not good product of quality.

Summary of the invention

The making method that the object of this invention is to provide a kind of bearing ball, the ball quality that this method is made is good, and the life-span is long, the running of energy effective guarantee machinery equipment.

The technological scheme adopting is:

A making method for bearing ball, comprises the following steps:

1), selection: selection material, then pier is thick, the roughing of forging and stamping.

2), then material is put into the press machine of 300 tons, 1000～1200 ℃ of temperature are carried out forge hot.

3), then carry out annealing in process, adopt anaerobic annealing furnace, 850～890 ℃ of annealing temperatures, are incubated 3～6 h, cooling.

4), carry out cold-rolling treatment after cooling, then put into hardening furnace and quench, 100～200 ℃ of temperature.

5) put into melting furnace and melt, thawing water is made a plurality of little ingot castings.

6), put into grinding machine and wear into ball.

Its advantage is:

The ball quality that this method is made is good, and the life-span is long, the running of energy effective guarantee machinery equipment.
