Abstract
The invention discloses a kind of piston rod processing technology, the processing technology includes following process：Rough forging-heat treatment quenching and tempering-rough turn-annealing-keyseat-ultrasonic examination-draw-bore-boring center oilhole-cylindrical grinding-spraying ceramic coat-nitridation heat treatment is steady-determines tempering heat treatment-Sic emery wheels fine grinding.The piston rod processing technology of the present invention, changes the physical characteristic of piston rod surface, process is simple and convenient to operate and surface treatment effect is good, is improved the fatigue resistance and wearability of piston rod, so as to substantially increase the quality of product, is reduced production cost.
Description
Technical field
The invention discloses a kind of piston rod processing technology.
Background technology
The piston rod that current most of hydraulic jack uses is general all after milling or pincers shaping, is ground, after grinding directly
Plating is connect, abrasive band polishing is carried out after plating, is then directly used；Because abrasive band particle is bigger, it is impossible to it is micro- to remove coating surface
Bits are electroplated between line, so as to which its surface shows that coating surface has wedge angle, uneven under the microscope, piston rod is under hyperbaric environment
Long-term move back and forth can cause cut to seal, and seal is fragile, while piston rod surface also has drawing trace, oil cylinder entirety
Service life, the lost of life.
The content of the invention
The technical solution adopted for the present invention to solve the technical problems is：A kind of piston rod processing technology, it is characterised in that：
The processing technology includes following process：Rough forging-heat treatment quenching and tempering-rough turn-annealing-keyseat-ultrasonic wave is visited
Wound-draw-bore-boring center oilhole-cylindrical grinding-spraying ceramic coat-nitridation heat treatment is steady-determines tempering heat treatment-Sic
Emery wheel refines.
The beneficial effects of the invention are as follows：The piston rod processing technology of the present invention, the physical characteristic of piston rod surface is changed,
Process is simple and convenient to operate and surface treatment effect is good, the fatigue resistance and wearability of piston rod is improved, so as to greatly improve
The quality of product, reduces production cost.
Embodiment
Specific embodiment：A kind of piston rod processing technology, it is characterised in that：The processing technology includes following process：Forging
Make outside blank-heat treatment quenching and tempering-rough turn-annealing-keyseat-ultrasonic examination-draw-bore-boring center oilhole-mill
Circle-spraying ceramic coat-nitridation heat treatment is steady-determines tempering heat treatment-Sic emery wheels fine grinding.
The beneficial effects of the invention are as follows：The piston rod processing technology of the present invention, the physical characteristic of piston rod surface is changed,
Process is simple and convenient to operate and surface treatment effect is good, the fatigue resistance and wearability of piston rod is improved, so as to greatly improve
The quality of product, reduces production cost.
Obviously, above-described embodiment is only intended to clearly illustrate example, and is not the restriction to embodiment.It is right
For those of ordinary skill in the art, can also make on the basis of the above description it is other it is various forms of change or
Change.There is no necessity and possibility to exhaust all the enbodiments.And the obvious change thus extended out or
Among changing still in the protection domain of the invention.
