So that mould is fixed on die frame.The through hole of mould is highly consistent with Workpiece clamping head, is in same central shaft
On line.When bar is cut by cutting system, with cutter system bar positioned and support, to be added
Keep a distance the shortest between cutting point and the location fix of work bar, make ultra-fine bar in lathe tool feed
Time do not produce flexural deformation.
Described feed system includes that feed bin, ejector beam and oil cylinder, described Workpiece clamping head can loosen and clamp bar.
When ejector beam is by bar jacking Workpiece clamping head, described gag lever post puts down, and meanwhile, Workpiece clamping head clamping is to be processed
Bar.Preferably, the horizontal range between gag lever post and Workpiece clamping head, can be according to bar processing length model
Enclose and be adjusted.
The present invention also provides for a kind of bar cutting process, the steps include:
1) feeding: feed bin put into by bar to be processed by operative employee, opens switch, performs numerical control program.
2) charging: ejector beam is by a bar jacking Workpiece clamping head, and gag lever post puts down, one end of same time bar
Contacting with gag lever post and Workpiece clamping head clamping bar, bar resets through the through hole of mould, gag lever post.
3) cutting: bar quickly rotates, with cutter system is along track X close to the position to be cut of bar；Cutting system
System and then moves on track X with cutter system synchronization, simultaneously cutting system according to numerical control program on track Y
Movable, bar is cut.
4) blanking: after cutwork completes, with cutter system and cutting system return to initial position, Workpiece clamping head loosens,
Next root bar enters Workpiece clamping head, the bar roof fall that will process, and is collected.
Beneficial effects of the present invention is, with bar is played location and supporting role in working angles by cutter system, makes
It is maintained at a distance the shortest between cutting point and the fixing point of bar to be processed, effectively solves ultra-fine
Charge bar overlength adds the difficult problem easily deformed by lathe tool bending man-hour.
