B.Carrying out the plug B diameter difference that lappingout obtains using the lapping setup of this improvement diameter of mandrel difference can control ± 0.2
Mm/m, efficiently reduce causes optical parameter to be scrapped in drawing process because diameter difference is larger, and it is comprehensive qualified to improve wire drawing
Rate.
Specific embodiment two: insufficient to segment length and interface diameter bumps difference plug docks and lappingout.Such as Fig. 3 institute
Show, first insufficient plug C long to two root segments is deoiled, cleans, dries, anneals and removed at residual stress after carrying out plug PK test
Then reason will be individually fixed on fixed chuck 2 and sliding clamp 3 through the long insufficient plug C of treated two root segment, beat
It is started switch, the fixed chuck 2, sliding clamp 3, blowtorch 4 and diameter scans instrument 6 on lapping setup electrically connect with controller
It connects, clicks the START button on controller, controller drives the bed surface along the first drive lead screw 5 and lappingout lathe 1 of blowtorch 4
Boss slideway 8 slides into the long butt end insufficient plug C of two root segments, light manually the insufficient plug C long to two root segments of blowtorch 4 into
Row heating, after being fully warmed-up, controller drives the boss of the bed surface along the first drive lead screw 5 and lappingout lathe 1 of sliding clamp 3
Slideway 8 is to the sliding of 2 end of fixed chuck until the long insufficient plug C of two root segments is somebody's turn to do to being connected in one to lappingout plug D to lappingout core
It is relatively large in diameter at stick D interface, controller is by control driving diameter scanner 6 along the second drive lead screw 7 and 1 side of lappingout lathe bed
8 traverse measurement of boss slideway in face waits for the diameter distribution situation of lappingout plug D, and the every 1mm of diameter scans instrument 6 scanning generates one directly
Diameter distributed intelligence to lappingout plug D is simultaneously fed back to controller by diameter data, according to the actual diameter distribution to lappingout plug D
Situation determines and needs lappingout position and aimed dia to lappingout plug D, controller combines the actual diameter to lappingout plug D
Distribution situation and aimed dia pass through control program and calculate lappingout tensile speed automatically, then controller control driving blowtorch 4
The boss slideway 8 of bed surface slides into required lappingout position along the first drive lead screw 5 and lappingout lathe 1, and it is right to light blowtorch 4 manually
It is heated to lappingout plug D, while the rotation axis of fixed chuck 2 and sliding clamp 3 drives to lappingout plug D synchronous rotary,
Sliding clamp 3 and blowtorch 4 are moved with lappingout tensile speed along the first drive lead screw 5, and 6 Real-time Feedback of diameter scans instrument waits for lappingout
The diameter data of plug D to controller, controller is drawn according to the lappingout that the diameter distribution situation of plug adjusts sliding clamp 3 in real time
Speed is stretched, until obtaining the plug E of uniform diameter.Short mandrel rod C is docked simultaneously using the lapping setup of this improvement diameter of mandrel difference
Plug Interface Shape can effectively be controlled by carrying out lappingout, optimize diameter uniformity, and the plug E diameter difference that lappingout obtains can be with
Control avoids scrapping caused by string diameter fluctuation in drawing process, improves pass rate of drawing, while passing through plug in ± 0.2 mm/m
Docking, lapping technique can guarantee that plug total length is up to standard, be plug in prepared prefabricated rods effective length, reduce former material
The waste of material, automatic operation, accurate and efficient, practicability is high.
