Compared with the prior art, the feeding frequency in the pipe continuous cutting process can be reduced substantially, the feeding efficiency is improved, and machining time is shortened; the feeding movements are executed by an interpolation shaft for cutting movements, and multiple feeding movements are combined into one-time feeding, so that the whole pipe continuous machining process is more efficient.

Description

The continuous cutting method of a kind of tubing
Technical field
The present invention relates to NC laser cutting field, specifically the continuous cutting method of a kind of tubing.
Background technology
In Laser cutting process, the continuous cutting of tubing is a basic problem always.The continuous cutting of tubing is the solution exceeding self-feeding in a kind of process of cutting machine impulse stroke for pipe length.Traditional continuous cutting adopts repeatedly feeding action, and often processes a figure, all call a feeding action, ensure that tubing to be cut is in impulse stroke, and then start the processing of next figure.If dimension of picture to be processed is less, feeding action can perform frequently; And the interpolation action due to tubing axis direction in feeding action and cutting process does not adopt same axle to perform usually, and the frequent reciprocating action of the extra feed spool increased, makes the working (machining) efficiency of numerical control laser cutter obviously decline.
Summary of the invention
The present invention, for overcoming the deficiencies in the prior art, designs a kind of feeding number of times that can significantly reduce in the continuous cutting process of tubing, and the continuous cutting method of the tubing improving feeding efficiency.
For achieving the above object, design the continuous cutting method of a kind of tubing, comprise laser cutting machine, it is characterized in that described cutting method is as follows:
(1) step 1: the process software opening laser cutting machine, cutting parameter is set, comprise the breadth stroke that pipe length, machine tooling are once required, also comprise tubing axis cut direction coordinate Y, part coordinate P, charging length and laser cutting head coordinate FirstHeadDist;
(2) step 2: import figure to be processed, and read the size of figure to be processed;
(3) step 3: treat graphics processing and carry out Laser cutting on tubing;
(4) step 4: after having cut, judges the magnitude relationship between current breadth remainder stroke and dimension of picture to be processed, if lathe breadth remainder stroke is greater than the size of figure to be processed, then performs step 3; Otherwise proceed to step 5, perform charging and judge;
(5) step 5: when execution charging judges, first judge the magnitude relationship of the breadth stroke that residue pipe length to be processed and machine tooling are once required, if remain pipe length to be processed when being more than or equal to the once required breadth stroke of machine tooling, then send material loading request, and perform step 3 again after material loading completes; Otherwise proceed to step 6, perform material loading action or terminate processing;
(6) step 6: perform material loading action or process finishing.
In described step 3, tubing axis cut direction coordinate Y increases, and part coordinate P increases, and charging length LengthFeeded is constant, and FirstHeadDist is constant for laser cutting head coordinate, remains pipe length to be processed and reduces gradually.
In described step 6, tubing axis cut direction coordinate Y reduces, and part coordinate P is constant, and charging length LengthFeeded increases, and FirstHeadDist is constant for laser cutting head coordinate, remains pipe length to be processed constant.
In described step 3 and step 6, tubing axis cut direction coordinate Y, part coordinate P, charging length LengthFeeded and laser cutting head coordinate FirstHeadDist maintain the balance of following equation: Y+LengthFeeded=P+FirstHeadDist.
The present invention compared with the existing technology, significantly can reduce the feeding number of times in the continuous cutting process of tubing, improve feeding efficiency, saves process time; Use the interpolation axle of cutting movement to perform feeding action, and repeatedly feeding action will be merged into a feeding, make whole tubing Continuous maching effectively.
Accompanying drawing explanation
Fig. 1 is cutting action flow chart of the present invention.
Fig. 2 is the schematic diagram implementing charging in cutting continuously in the present invention.
Detailed description of the invention
The present invention is described further with reference to the accompanying drawings below.
As shown in Figure 1, first open the process software of laser cutting machine, and pipe length and lathe breadth stroke are set in software, the figure processed as required subsequently, the sized data of figure is imported process software.
Start processing, in process, tubing axis cut direction Y increases, part coordinate P increases, charging length LengthFeeded is constant, and FirstHeadDist is constant for cutting head coordinate, remains pipe length to be processed and reduces simultaneously in process, coordinate real-time change, but equation (1) maintains balance:
Y+LengthFeeded=P+FirstHeadDist formula (1);
After machining, judge the magnitude relationship of current breadth remainder stroke and working image size, if breadth remainder stroke is greater than dimension of picture, then continue graphics processing, otherwise perform charging judgement.
When charging judges, the magnitude relationship according to residue pipe length and tailing length judges, when residue tubing reaches the tailing length of setting, does not then perform charging action, performs and send material loading request; Otherwise perform charging action.
In fill process, tubing axis cut direction Y reduces, and part coordinate P is constant, and charging length LengthFeeded increases, and residue pipe length is constant; Simultaneously in fill process, coordinate real-time change, but still the balance following equation (1).
As shown in Figure 2, left side is dynamic chuck, right side for determine chuck, dynamic chuck and determine chuck and all possess latch functions, continuous cut in real-time charging and processing method comprise the steps:
(1) process 1, along the interpolation of tubing axis direction, after often processing a part, judges whether continue processing or perform charging; In process, dynamic chuck closes, and determines chuck and unclamps;
(2) when breadth remainder stroke is less than working image size, charging action is performed;
(3) start charging, determine chuck and close, dynamic chuck unclamps, Y-axis rollback;
(4) feeding terminates, and dynamic chuck closes, and determines chuck and unclamps, start to perform next section of process;
(5) next section of process starts, circulation Continuous maching, until residue pipe length reaches tailing restriction.
