Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

Fig. 1 schematically shows a layout setting interface of a simple close-packed processing method based on laser pipe cutting according to an embodiment of the present invention, fig. 2 shows a simple close-packed processing flow of the simple close-packed processing method based on laser pipe cutting in fig. 1, fig. 3 shows a simple close-packed inversion algorithm flow of the simple close-packed processing method based on laser pipe cutting in fig. 1, and fig. 4 shows a simple close-packed inversion condition of the simple close-packed processing method based on laser pipe cutting in fig. 1. As shown in fig. 1-4, the method is used for laser cutting of a tube stock to form a pattern, i.e., automatically cutting the tube stock into a plurality of tube stock patterns arranged side by side, to machine a desired target part. When the method is used, a corresponding program needs to be set, a relevant system is used for operation, and the system is provided with a relevant operation interface such as a layout setting interface.

The method comprises several main steps, as described in detail below.

The method comprises the following steps of firstly, inputting the number N of stock layout and the spacing distance D on a stock layout setting interface, namely, cutting a pipe into a plurality of stock layout and setting the specific distance between adjacent stock layout.

And secondly, selecting a reverse rotation function and a common edge function on a layout setting interface, wherein the pipe can be reversed during processing after the reverse rotation function is selected, and whether adjacent layouts can share one end face during processing can be judged after the common edge function is selected.

After the reversing function is selected and started, when the pipe is reversed during machining, the system can firstly judge whether the current pipe meets the simple close arrangement condition, the judging conditions are two, one is to judge whether the number of the cut lines is less than 2, the other is to judge whether the outside of the pipe is provided with a hole, wherein the simple close arrangement condition is met when the two conditions are all negative, when any one of the two conditions is positive or all positive, the simple close arrangement condition is not met, at the moment, the system can send a corresponding signal to prompt that the close arrangement condition is not met, and the machining is finished.

After the current pipe is judged to meet the simple close packing condition, two single sample arrangements can be made on the current pipe, namely 'reverse' sample arrangement and 'reverse + rotation' sample arrangement. As shown in fig. 4, an XYZ axis three-dimensional coordinate system is established, and the left side of fig. 4 takes a certain point a before inversion on the tube as an example, and the tube is rotated 180 ° around the X1 axis by taking the center line of the rightmost boundary line m of the tube and one axis X1 parallel to the X axis, and the right side of fig. 4 shows the tube and the position after inversion of the point a.

And thirdly, automatically calculating the shortest close-packed distance.

After the processing is started, the system can respectively and automatically calculate the shortest close packing distance of two kinds of single sample arrangements, and the shortest close packing distance is taken as the optimal sample arrangement value, so that the distance is realized in the optimal sample arrangement mode.

And fourthly, performing single-piece layout calculation according to the close-packed distance.

After the optimal stock layout mode is selected, the pipe subjected to reverse stock layout can be used as a whole to perform single-piece stock layout work, namely the condition that the pipe is cut into a plurality of parts is calculated. Before this step, the position of the reversed layout path can be properly adjusted according to the situation so as to facilitate layout.

In addition, under the condition that the common edge function is selected, when the system performs single piece layout calculation, whether the end surfaces between every two adjacent parts are the same or not is judged firstly, if the end surfaces are the same, the two parts can share one end surface during processing, so that unnecessary processing work and waste materials generated between the parts can be reduced, and the working efficiency is improved.

And fifthly, after the close packing is finished, turning out a machinable NC gear, starting machining, and machining the target parts of the pipes in batches by a simple close packing method.

What has been described above are merely some embodiments of the present invention. It will be apparent to those skilled in the art that various changes and modifications can be made without departing from the inventive concept thereof, and these changes and modifications can be made without departing from the spirit and scope of the invention.
