Description

Technical Field

[0001] This invention relates to the field of laser tube cutting machine technology, and more particularly to the field of simultaneous cutting and feeding control. Specifically, it relates to a method, apparatus, processor, and computer-readable storage medium for achieving simultaneous cutting and feeding in a four-chuck laser tube cutting machine. Background Technology

[0002] The laser cutting process is as follows: loading → cutting → unloading. Typically, the tube is held by the rear chuck and fed under the cutting head for processing. Since the portion of the tube held by the rear chuck's jaws cannot be cut, the front chuck is usually used to complete the cutting of the last part to achieve zero waste. For mass production scenarios, current technology requires waiting for a single cut to complete, unloading, and then loading again for the next round of processing. Based on the machine's structural and processing characteristics, when the tube is being cut by the unloading chuck, the feeding side can simultaneously load the tube, saving waiting time and improving the efficiency of mass production. Summary of the Invention

[0017] The present invention provides a method for simultaneous cutting and feeding in a four-chuck laser tube cutting machine, comprising the following steps: (1) Switch to zero tail material status; (2) Perform the process piling after the zero tail material attitude switch; (3) Perform zero-tail material posture cutting; (4) Perform material feeding.

[0018] In a preferred embodiment of the present invention, the four-chuck laser tube cutting machine includes a cutting head, four chucks, and a support frame. The left side of the cutting head is the feeding side, and the right side of the cutting head is the discharging side. The support frame is distributed on both sides of the cutting head, and the four chucks are distributed on both sides of the cutting head.

[0019] In a preferred embodiment of the present invention, step (1) specifically includes the following steps: (1.1) Level the four B axes, the rear chuck clamps the pipe and sends the pipe end to the position where the front chuck can clamp it, clamps the jaws of the front chuck, releases the jaws of the rear chuck, and the chuck on the discharge side clamps the pipe and moves to complete the cutting. (1.2) Switch the main rotation axis from B1 axis to B4 axis, couple B2 axis, B3 axis and B4 axis to follow the toolpath trajectory; decouple B1 axis and stop following the toolpath trajectory. (1.3) The discharge side support frame moves with the lowest point of the pipe; the feed side support frame is decoupled.

[0020] In a preferred embodiment of the present invention, step (2) specifically includes the following steps: (2.1) Lower the feed-side support frame; (2.2) Move the Y1 axis to the safe loading position; (2.3) Extend the loading arm; (2.4) Raise the feed side support frame; (2.5) Retracting the loading robot; (2.6) Determine whether the cutting of the leftover material is finished. If yes, continue to step (2.7); otherwise, continue to step (2.6). (2.7) Decouple axis B2 from axis B4; (2.8) Rotate axes B1 and B2 to a specific angle; (2.9) Move the Y1 axis to the loading clamping position; (2.10) The jaws of the chuck after clamping; (2.11) After the tail material cutting is completed, move the Y1 axis to the machining position; (2.12) Clamp the jaws of the chuck.

[0021] The present invention relates to a device for simultaneously cutting and feeding materials in a four-chuck laser tube cutting machine, wherein the device comprises: A processor is configured to execute computer-executable instructions; The memory stores one or more computer-executable instructions, which, when executed by the processor, implement the various steps of the above-described method for simultaneous cutting and feeding of a four-chuck laser tube cutter.

[0022] The present invention relates to a processor for a four-chuck laser tube cutter that enables simultaneous cutting and feeding, wherein the processor is configured to execute computer-executable instructions, and when the computer-executable instructions are executed by the processor, the various steps of the above-described method for simultaneous cutting and feeding of a four-chuck laser tube cutter are implemented.

[0023] The computer-readable storage medium of the present invention stores a computer program that can be executed by a processor to implement the various steps of the above-described method for simultaneous cutting and feeding of a four-chuck laser tube cutter.

[0024] This invention relates to the field of laser tube cutting machine technology, and in particular to the parallel control of laser cutting and feeding. Specifically, it refers to a control method for a four-chuck laser tube cutting machine to achieve simultaneous cutting and feeding, which can improve the processing efficiency of mass production.

[0025] Figure 1 This diagram illustrates a four-chuck laser tube cutting machine with simultaneous cutting and feeding. The cutting head 1 serves as the dividing line; the left side of cutting head 1 is the feeding side, and the right side is the discharging side. Feeding occurs from the feeding side, and processed parts are unloaded from the discharging side. The four-chuck laser tube cutting machine includes a cutting head 1, four chucks 2, and a support frame 3. The support frame is located on both sides of the cutting head, and the four chucks are distributed on both sides of the cutting head, from left to right: rear chuck C1, middle chuck C2, middle chuck C3, and front chuck C4.

[0026] Each chuck has two degrees of freedom: horizontal motion and horizontal rotation. The axis for horizontal motion is the Y-axis, and the axis for horizontal rotation is the B-axis. All four chucks can move horizontally, and their axes of horizontal motion from left to right are Y1, Y2, Y3, and Y4. Their axes of horizontal rotation from left to right are B1, B2, B3, and B4.

[0027] The support frame moves with the lowest point of the pipe, providing support during processing and assisting in loading and unloading. When the pipe is clamped and cut by the chuck on the discharge side, it can be loaded simultaneously on the feed side.

[0028] In a specific embodiment of the present invention, the method for the four-chuck laser tube cutting system to achieve simultaneous cutting and feeding is as follows: Figure 2 As shown, the method includes the following steps: Step 1: Switch to zero tailings status.

[0029] Step 2: Perform the process piling after switching to zero tail material attitude. Step 3: Zero-tail cutting.

[0030] Step 4: Unload the material.

[0031] Step 1 specifically includes: S11: Level the four B axes, the C1 chuck clamps the pipe and sends the pipe end to the position where the C4 chuck can clamp it. The C4 jaws clamp, and the C1 jaws release.

[0032] S12: Switch the main rotary axis from B1 to B4. B2, B3, and B4 are coupled and move along the toolpath; B1 is decoupled and no longer follows the toolpath. The coupling of B2, B3, and B4 refers to the amount of movement of B4; B2 and B3 move in a 1:1 ratio with B4 to prevent pipe twisting. B2 follows B4 to prevent the pipe from colliding with the C2 chuck if the tail section is too long.

[0033] S13: The discharge side support frame moves with the lowest point of the pipe; the feed side support frame is decoupled and no longer moves according to the lowest point of the pipe.

[0034] Step 2, as described above, starts another thread, AssistPE, to perform the loading action. MainPE continues to perform subsequent actions. The loading action specifically includes the following steps: S21: The feed side support frame descends.

[0035] S22: The Y1 axis moves to the safe loading position.

[0036] S23: Loading arm extends.

[0037] S24: The feed side support frame rises.

[0038] S25: The loading robot arm retracts.

[0039] S26: Is the cutting of the remaining material finished? If yes, proceed to S27; otherwise, proceed to S26.

[0040] S27: B2 and B4 are decoupled.

[0041] S28: B1 and B2 are rotated to a specific angle.

[0042] S29: The Y1 axis moves to the loading clamping position.

[0043] S210: C1 jaws clamp.

[0044] S211: After the zero-tail material cutting is completed, the Y1 axis moves to the processing position.

[0045] S212: C2 jaws clamp.

[0046] S213: End.
