Embodiment 1

[0015] A method for manufacturing bearing balls, comprising the following steps:

[0016] 1), material selection: select the material, and then pier rough, forging rough processing.

[0017] 2) Then, put the material into a 300-ton press and perform hot forging at a temperature of 1000°C.

[0018] 3) Then perform annealing treatment, using an oxygen-free annealing furnace, the annealing temperature is 850°C, keep warm for 3 hours, and cool down.

[0019] 4) After cooling, carry out cold rolling treatment, and then put it into a quenching furnace for quenching at a temperature of 100°C.

[0020] 5) Put it into a melting furnace for melting, and melt water to make a plurality of small ingots.

[0021] 6), put into the mill and grind into balls.

Embodiment 2

[0023] A method for manufacturing bearing balls, comprising the following steps:

[0024] 1), material selection: select the material, and then pier rough, forging rough processing.

[0025] 2), and then put the material into a 300-ton press, and carry out hot forging at a temperature of 1200°C.

[0026] 3) Then annealing treatment is carried out in an oxygen-free annealing furnace, the annealing temperature is 890°C, the temperature is kept for 6 hours, and then cooled.

[0027] 4) After cooling, carry out cold rolling treatment, and then put it into a quenching furnace for quenching at a temperature of 200°C.

[0028] 5) Put it into a melting furnace for melting, and melt water to make a plurality of small ingots.

[0029] 6), put into the mill and grind into balls.

Embodiment 3

[0031] A method for manufacturing bearing balls, comprising the following steps:

[0032] 1), material selection: select the material, and then pier rough, forging rough processing.

[0033] 2) Then, put the material into a 300-ton press and perform hot forging at a temperature of 1100°C.

[0034] 3) Then perform annealing treatment, using an oxygen-free annealing furnace, the annealing temperature is 840°C, keep warm for 4 hours, and cool down.

[0035] 4) After cooling, carry out cold rolling treatment, and then put into a quenching furnace for quenching at a temperature of 150°C.

[0036] 5) Put it into a melting furnace for melting, and melt water to make a plurality of small ingots.

[0037] 6), put into the mill and grind into balls.

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.
