Abstract
The invention relates to a quenching process, particularly relates to an isothermal quenching self-shaping process for a large-scale sleeve in a salt bath, and belongs to the field of bearing processing technology. Compared with a conventional process, the isothermal quenching self-shaping process has the following outstanding advantages and positive effects that the process simplifies procedures, changes original procedures of strutting a low point for reshaping-tempering with a holder -unloading the holder after tempering into the present procedures of hanging the low point with an iron hook-entering into a salt bath for isothermality, reduces artificial participation, saves manpower resource, increases production efficiency and reduces production cost.
Description
Technical field
The present invention relates to a kind of quenching technology, relate in particular to a kind of big style ferrules salt bath austempering from shaping process, it belongs to technical field of bearing processing.
Background technology
Along with the continuous evolution of the human civilization high speed development with science and technology, bearing industry is from small and weak starting, difficult foundation; Cut-throat competition; Tortuous development, by several wife and children factory in the past develop into now spread all over the world, a year sales volume volume reaches 30,000,000,000 dollars scale, obtained astonishing achievements.Usually press the difference of rolling body kind in the bearing, it is divided into ball bearing and roller bearing, and be divided into radial bearing and thrust block by the main action direction that bearing can bear load.At present the bearing general technology of quenching is: shaping after the amount shape earlier behind the heat-treatment quenching, through the finished product band holder tempering of shaping, unload holder after the tempering again, tempering setting again after amount shape is qualified.Its technological process is: unload holder → measure again operation under shape → friendship after isothermal quenching → control salt → quantitative change shape → support low spot shaping → band holder tempering → tempering.The principle of this method is: utilize the self gravitation of big style ferrules, hang low spot with the self-control cleek, in salt bath saline solution isothermal structural transformation process, reach from shaping.Training time is long, and time-consuming in the technological process, the effort and take.
Summary of the invention
In order to solve the problem that prior art exists, the objective of the invention is to provide big style ferrules salt bath austempering from shaping process.
For realizing above-mentioned purpose, the big style ferrules salt bath austempering of the technical solution that the present invention adopted is from shaping process, and its technological process is:
A, isothermal quenching;
B, control salt;
C, quantitative change shape;
D, cleek are hung low spot;
E, entering salt bath isothermal;
Measure shape behind f, the isothermal again.
The present invention compared with prior art; Have following outstanding advantage and positively effect: this method has been simplified technological process; Change that to unload the holder process after original support low spot shaping → band holder tempering → tempering be that cleek is hung low spot → enterings salt bath isothermal, reduced artificial participation, the saving manpower; And promptly increased production efficiency, reduced production cost again.
Embodiment
The big style ferrules salt bath austempering of the technical solution that the present invention adopted is from shaping process, and its technological process is:
A, isothermal quenching;
B, control salt;
C, quantitative change shape;
D, cleek are hung low spot;
E, entering salt bath isothermal;
Measure shape behind f, the isothermal again.
