Technical Field

The invention relates to the field of laser pipe cutting, in particular to a processing method for realizing automatic tailing processing based on laser pipe cutting.

Background

In the process of cutting the pipe by using the laser cutting equipment, a certain material loss generally occurs. In the case that the raw material of the pipe is long, in actual processing, if the last remaining tailings are directly calculated through parameters such as the length of the pipe, the length of the workpiece, the clamping allowance of the chuck and the like, the accuracy is often insufficient, and the cutting times are reduced by one time. In addition, in batch processing, a new batch of pipes are changed every time, the length of the pipes needs to be input again, more manpower and material resources can be consumed, even if the length of the same batch of pipes can be set to be consistent, the length of the pipes does not need to be input again, and when the next batch of pipes are changed, certain fine adjustment is still needed to be carried out on parameters.

In some embodiments, in step 2), the tailing cuttable number is the difference between the distance from the sensor to the origin and the clamping margin of the chuck divided by the length of the workpiece. Thus, a method for calculating the cuttable times of the tailings in the step 2) is described.

In some embodiments, in step 2), the calculated tailing cuttable times are displayed in a tailing monitoring interface. Therefore, the tailing monitoring interface can be used for displaying the cutting times of the tailing.

As shown in fig. 1-3, the apparatus of the processing method mainly includes a chuck 1, the chuck 1 is used for holding a pipe 4 to be cut and feeding, and the direction of the arrow in fig. 1 is the feeding direction. Each part of the tube 4 is detected by the sensor 2 before reaching the chuck 1, and is cut by a laser cutting device (shown as a laser beam by an inverted triangle) after passing through the chuck 1. In the machining, the pipe 4 is cut into a plurality of pieces of fixed length (shown by broken lines in the figure).

The specific processing method comprises the following steps.

In the first step, the chuck 1, the sensor 2, the laser cutting device, etc. are set at appropriate positions, and corresponding parameters are measured. Wherein, the position for laser cutting is set as the origin 3, and the parameters to be set and measured are the clamping allowance of the chuck 1, i.e. the clamping allowance of the chuck 1 is the distance from the center of the chuck 1 to the origin 3, and the distance from the sensor 2 to the origin 3.

And secondly, starting the equipment for machining, inputting numerical values of parameters measured in the previous step into a control system, namely the clamping allowance of the chuck 1 and the distance from the sensor 2 to the origin 3, adding the length of the workpiece required after machining, and calculating the cutting times of the tailings according to the numerical values.

The number of cutting times of the tailings is obtained by dividing the difference between the distance from the sensor 2 to the origin 3 and the clamping allowance of the chuck 1 by the length of the workpiece, namely, the distance from the sensor 2 to the origin 3 is a, the clamping allowance of the chuck 1 is b, the length of the workpiece is m, the number of cutting times of the tailings is (a-b)/m, and an integer is taken from the result.

The control system is also provided with a monitoring interface, and the calculated cutting times of the tailings can be displayed in the tailing monitoring interface.

And thirdly, detecting the pipe 4 in real time by using the sensor 2 to judge whether to enter a tailing processing stage. When the pipe 4 cannot be detected by the sensor 2, judging that a tailing processing stage is entered, and cutting the pipe 4 at the moment by corresponding times according to the calculated tailing cutting times.

And the number of times of cutting the tailings and the characters in the cutting of the tailings are displayed in real time in the monitoring interface.

In addition, the monitoring interface is also provided with a tailing resetting function key, and data in the monitoring interface can be reset by clicking the function key.

And fourthly, when the cutting times of the tailings reach the calculated times, finishing the processing, and automatically discharging the residual tailings.

Wherein, in the tailing processing stage, can also judge automatically whether chuck 1 can the centre gripping according to tailing surplus length to can in time stop processing and discharge surplus tailing, and avoid appearing the condition that makes chuck 1 unable centre gripping and drop because of the tailing is short excessively.
