Prepare, 2500mm metal bar materials long are positioned on bin 1, the first clamping device 3 now and the second material folding
Device 4 is all in order at releasing orientation, and metal bar material is placed in the second clamping device 4, and metal bar material one end through the
The through hole 321 of one clamping device 3.Cutting position to the cutting for the first time of every metal bar material is carried out initially with " craft " mode
Positioning, follow-up off-position carries out following automatic cut-to-length feedings.The first time cut-out of every virgin material is " material head ", material
Head is generally not the product that we need.
Self-feeding, in the first clamping device 3, the second clamping device 4 unclamps the front end portion grips of metal bar material, feeding
Device 2 drives the second clamping device 4 away from the first clamping device 3, and reaches stopping after predeterminated position, and the second clamping device 4 is pressed from both sides
Tightly, the first clamping device 3 unclamps, and feed device 2 drives the second clamping device 4 to be moved close to the first clamping device 3 again, with
The follow-up cutting position of adjustment metal bar material leading section（Except for the first time）Position in the first clamping device 3；Follow-up cutting
After position determines, the band cutting position on metal bar material is directed at saw blade 51, after cutting position is had good positioning, the first clamping device
3 clamp.After the completion of first clamping device 3 is clamped, start surface trimming program.
Surface trimming, after metal bar material positioning terminates, saw blade 51 carries out high speed rotation under the driving of electric rotating machine 52, and
And the cutting position in metal bar material in the first clamping device 3 is quickly moved close under the driving of servomotor 53, then
Advance at a slow speed and metal bar material is cut off, after cut-out stroke is finished, saw blade 51 quickly withdraws under the drive of servomotor 53.
Cooling, during cutting, the startup optimization of Oil pump electrical machinery 111, by the cutting fluid in fuel tank 112 from spray head
113 carry out spraying cooling against cutting work station.Cutting fluid is gathered on workbench 6 and is back to fuel tank 112, repeats after filtering
Utilize.
Embodiment above is merely illustrative and not limiting to the invention, therefore all according to described in present patent application scope
The equivalent change or modification done of method, be included in the range of present patent application.
