Control method for realizing efficient idle operation in laser pipe cutter

Abstract

The invention provides a control method for realizing efficient idle-moving in a laser pipe cutter. The generalized diameter TD of a pipe is involved, namely the minimum encirclement ring diameter ofthe section of the pipe; the Z-axis idle-moving safe offset height Hs, the Z-axis gun-removing safe offset height Ha, the horizontal-moving safe offset height Hp, the pipe surface Z-axis height Ht, the maximum horizontal-moving distance D1 and the maximum leapfrog distance D2 are set, and the pipe rotating direction is the direction A; according to position information between the current contourand the next contour, four different idle-moving codes are output, namely direct horizontal moving, gun-raising horizontal moving, leapfrog idle moving and portal idle moving; and a numerical controlsystem is matched with a height sensing system to control all axes to complete different idle moving processes according to the different idle-moving codes, and on the premise of guaranteeing safety,ineffective machining time is shortened, and the idle-moving efficiency is improved to the maximum.

Description

technical field [0001] The invention relates to the field of laser pipe cutting machines, in particular to a control method for realizing high-efficiency dry running in the laser pipe cutting machine. Background technique [0002] Laser pipe cutting machine is a special equipment for cutting, welding, marking, engraving, surface treatment, fine processing and other processes of pipes by using high-energy laser beams. The laser pipe cutting machining system consists of at least six parts, namely the pipe cutting machine body, chuck, laser, laser cutting head, height tracking system, electrical control system, etc. In the current processing technology, the energy consumption of equipment and the loss of auxiliary materials are relatively large. When this part of loss cannot be reduced, how to control the ratio of the actual effective processing time to the total processing time and reduce the processing time of single parts and the entire pipe, becomes particularly important....

AI Technical Summary

Problems solved by technology

In such a control cycle, the risk of collision between the cutting head and the pipe can be effectively avoided, but the invalid processing time is long, and the processing efficiency is greatly reduced

[0004] This kind of air movement method requires the operator to pay great attention to the setting of the safety height. Before the processing starts, it is necessary to check whether the safety height is set enough. If the setting is wrong, there will still be a risk of collision.
