Abstract
A kind of bearing steel gauge block Technology for Heating Processing, it is characterized in that by preheating, quenching, freezing processing, Ageing Treatment, insulation, grinding technics step.Workpiece surface hardness after treatment is high, anti-wear performance is good, high precision.
Description
Technical field
The present invention relates to the heat treatment method in a kind of machining, particularly a kind of bearing steel gauge block Technology for Heating Processing.
Background technology
In the prior art, when being heat-treated to bearing steel gauge block, generally using first modifier treatment, then nitrogencase hardening technique is carried out, is processed
Easily there is phenomena of dimensional variation in use in gauge block afterwards, and precise decreasing, measurement error is big.
The content of the invention
The invention aims to overcome above-mentioned weak point, and provide that the workpiece surface hardness after a kind for the treatment of is high, anti-wear performance is good, precision
Bearing steel gauge block Technology for Heating Processing high.
For achieving the above object, the concrete technology step that the present invention is used is as follows：
1st, preheat：The workpiece processed through spheroidizing is placed in heating furnace, at a temperature of 500 DEG C~600 DEG C preheat 30~
35 minutes.
2nd, quench：To be placed in middle thermohaline liquid furnace through the workpiece after above-mentioned preheating, be incubated at a temperature of 840 DEG C~850 DEG C
After 18~22 minutes, workpiece is taken out, is cooled down in quench rapidly light diesel fuel or No. 10 machine oil, taken out when workpiece temperature is down to 200 DEG C,
Rinsed well with water.
3rd, freezing processing：Workpiece after quenched treatment was put into household freezer in time in 30 minutes,
2~4 hours are incubated at a temperature of -75 DEG C~-80 DEG C.
4th, Ageing Treatment：After will be chilled workpiece corase grind after, be placed in oil oven incubator, at a temperature of 110 DEG C~120 DEG C be incubated 35~
After 36 hours, slow cooling is taken out.
5th, it is incubated, grinds：After being refined through the workpiece after Ageing Treatment, place into oil oven incubator, protected at a temperature of 110 DEG C~120 DEG C
Temperature is transferred to grinding step after 7.5~8 hours.
, due to using process above method, workpiece surface hardness after treatment is high, anti-wear performance is good, high precision for the present invention.
Specific embodiment
1st, HB187~207,2~4 grades of the spheroidizing pearlite of metallographic structure, carbide segregation≤3 will be reached through the hardness after spheroidizing
The workpiece of level is placed in heating furnace, is preheated 30~35 minutes at a temperature of 500 DEG C~600 DEG C.2nd, will be through above-mentioned preheating
Workpiece afterwards is placed in middle thermohaline liquid furnace, at a temperature of 840 DEG C~850 DEG C be incubated 18~
After 22 minutes, workpiece is taken out, cooled down in quench rapidly light diesel fuel or No. 10 machine oil, taken out when workpiece temperature is down to 200 DEG C, rushed with water
Wash clean.
3rd, will be put into household freezer in time in 30 minutes through the workpiece after above-mentioned Quenching Treatment, at a temperature of -75 DEG C~-80 DEG C be incubated 2~
4 hours.
4th, after being roughly ground through the workpiece after above-mentioned freezing, it is placed in oil oven incubator, 35~36 is incubated at a temperature of 110 DEG C~120 DEG C small
Shi Hou, takes out slow cooling.
5th, after being refined through the workpiece after above-mentioned Ageing Treatment, place into oil oven incubator, 7.5~8 are incubated at a temperature of 110 DEG C~120 DEG C
Grinding step is transferred to after hour.
