Abstract
The technical procedure is applying medium carbon steel as material to process normal turning process and surface chromeplete->nospark grinding-> superfine polishing. The specific procedure is: to have the workpiece rotated on the polishing equipment, spray polishing liquid on the polishing ara. the polishing area contacts to the workpiece and rotates anticlockwisely.
Description
Technical field
The present invention relates to nitrogen spring, especially the processing technology of nitrogen spring piston rod.
Background technique
Nitrogen spring is a kind of novel spring function element, mainly form by cylinder barrel, piston rod, support ring, basic principle is that high pressure nitrogen is sealed in the container, compression and expansion by high pressure nitrogen, obtain certain elastic force, it is the upgrading regeneration product of spiral bullet, rubber mount, air cushion, air cushion.Its main feature is: elastic force pressure is big, the easy balance of elastic force pressure, and easily simplified design and shortening cycle, long service life, safe and reliable, easy to maintenance, additionaling power source apparatus not.Nitrogen spring extensive use and automobile, mould, electronics, light industry.Have only a few countries productions such as the U.S., Italy, Sweden, France, Korea S at present in the world, nitrogen spring does not still have manufacturer in China, cause the price of nitrogen spring high and haulage time is long,, have vast market prospect as if Development and Production at home.Nitrogen spring mainly is made of cylinder barrel, piston rod, end cap, guide collar, sealing assembling, and wherein cylinder barrel comprises casing wall and cylinder bottom, and the part of most critical is cylinder barrel and piston (plunger) bar in the described nitrogen spring.
Summary of the invention
The objective of the invention is Development and Production nitrogen spring at home, reduce nitrogen spring price at home, control the cost of production of nitrogen spring, a kind of processing technology of nitrogen spring piston rod is provided for this reason.
The processing technology of described piston rod is: it is that raw material carry out conventional turning processing and the ultra-fine polishing of chrome-faced → sparking out → nanometer that piston rod is selected middle-carbon steel for use; Wherein the detailed process of the ultra-fine polishing of nanometer is: workpiece is contained on the polissoir main shaft rotates, spray nanometer burnishing liquid at polishing belt, polishing belt is contacted with workpiece, and be rotated counterclockwise polishing belt.
In the processing technology of above-mentioned piston rod, adopt sparking out and the ultra-fine polishing of nanometer, improved the surface quality of workpiece,, reduce the surface imperfection of workpiece by the ultra-fine polishing of nanometer, improved workpiece wearability and working life.
Description of drawings
Fig. 1 is a kind of structural representation of nitrogen spring piston rod.
Embodiment
It is material that nitrogen spring piston rod is as shown in Figure 1 selected No. 50 carbon steel for use, and its processing technology is: blanking → flat both ends of the surface, the ultra-fine polishing of cylindrical turning → cylindrical grinding → chrome-faced → sparking out → nanometer.Wherein the detailed process of the ultra-fine polishing of nanometer is: workpiece is contained on the polissoir main shaft rotates, spray nanometer burnishing liquid at polishing belt, polishing belt is contacted with workpiece, and be rotated counterclockwise polishing belt, pressure between polishing belt and the workpiece is not higher than 1MPa, divides three polishings, every polishing 2-3 second, need spray nanometer burnishing liquid again one time, guarantee roughness Ra0.01um.Wherein said polissoir is by frame, unit head, polishing frame, form with top tailstock; Unit head is used for rotational workpieces, and the polishing frame is used to drive polishing belt.
