Accompanying drawing explanation
Fig. 1 is the part typesetting figure in the embodiment of the present invention 2, same steel plate carrying out rush-harvesting and rush-planting cutting;
Fig. 2 is the part typesetting figure of the striking crossover cutting in the embodiment of the present invention 3.
Detailed description of the invention
Below in conjunction with accompanying drawing embodiment, the present invention is described in further detail.
Embodiment 1
Digit Control Machine Tool arranges two burning torches, and two burning torches do synchronous cutting operation by same programme-control, two burning torch synchronous cutting operations on the steel plate of two pieces of parallel placements respectively.When jacking, the specification of two steel plates, part, program are just the same; When Numerical control cutting, two steel plates placed side by side on moulding bed, two each corresponding burning torches of steel plate, on same Digit Control Machine Tool, two burning torches are cut the part of same specification by same programme-control.
Said method need meet following implementation condition:
1, cut moulding bed width need meet certain requirements, namely must be greater than two steel plate widths;
2, about the requirement of the number of parts on same steel plate, number of parts should can fill up two plates as far as possible, otherwise by generation two blocks of clouts, increase material secondary is had bad luck, stockyard use cost.
Implementation step:
One, typesetting
Part is imported software for composing by the quantity after process, typesetting according to a conventional method, preservation clout.Notice that now preserved clout is two pieces.
Two, blanking
By two steel plate lay out in parallel on moulding bed.Two burning torches installed by a numerical control cutting machine.Adjustment rifle mouth position makes it the lower left corner aiming at typesetting figure light plate, then follow procedure cutting.
Embodiment 2
Digit Control Machine Tool arranges two burning torches, and two burning torches do synchronous cutting operation by same programme-control, and two burning torches do synchronous cutting action on a steel plate.
On a steel plate, rush-harvesting and rush-planting cutting a steel plate is rule in the width direction be divided into two parts, part, the program of left-right parts are completely the same, two parts part interval 12 ~ 15mm, left-right parts each corresponding one is burning torch, and on same Digit Control Machine Tool, two burning torches are cut the part of same specification simultaneously by same programme-control.With the steel plate lower left corner for the origin of coordinates, cut from the steel plate lower left corner, component clearance is 6mm; Cutting is compensated for as 1 ~ 3mm; Oxygen pressure 0.6 ~ 0.9MPa, propane pressure is 0.05 ~ 0.15MPa, and cutting speed is generally 200 ~ 600mm/min.
