Abstract
The invention relates to the technical field of a laser cutting process, in particular to a laser cutting process for a film coated metal plate. The laser cutting process for the film coated metal plate comprises the following steps of: (1) placing the film coated metal plate which needs to be cut on a laser machine station; (2) burning out a film, i.e. under the action of compressed air, burning out the surface coated film of a path track of the metal plate, which needs to be cut, so as to form a film burning track with the width of 1 to 2.5mm; and (3) carrying out laser cutting along the film burning track to form a required workpiece. After the film burning track on the cutting path is formed by burning the film, the normal cutting process is carried out, so that the problems of shifting of the metal film coated plate, malposition of the cutting path, scrappage and the like in the process of cutting a conventional metal film coated plate are avoided; the problem that reverse slags are formed on the surface of the film coated plate in the conventional cutting process to influence the surface of the film coated plate is also avoided; and the scrappage of a product is reduced and the surface quality of the product is improved.
Description
Technical field:
The present invention relates to the laser cutting parameter technical field, relate in particular to a kind of laser cutting parameter of precoated metal plate.
Background technology:
The laser machine cuts the processing that is widely used in various sheet material workpiece; Have the precision height, speed is fast, cost performance is high, use cost is low and the automaticity advantages of higher is used widely; Especially in the processing of the workpiece of metallic plate; Have that the heat affected area is little, the automated programming cutting, have incomparable advantage in the processing modes such as more traditional line cutting, grinding tool punching press; Common some metallic plate, because the surface needs protection through the surface coverage layer of protecting plastic foil of being everlasting, there is following problem in the cut of common this precoated metal plate; Cut is cut owing to blast high voltage protective gas when cutting, when cutting precoated metal plate; Gases at high pressure get in the diaphragm from the cut place easily; Diaphragm forms " bulge " at metal sheet surface, when cutting head in processes such as cutting news line, feed, " bulge " of diaphragm can the interference cutting head; Even occur because of " bulge " diaphragm on cutting head and dragged metal film coated plate; The metal film coated plate displacement causes the cutting route on metallic plate to misplace, and causes scrapping under the serious situation; Because the cutting slag follows the plastic foil slag to splash, form anti-slag on the film coated plate surface, influence the surface of film coated plate.
Summary of the invention:
The object of the invention is exactly the laser cutting parameter that a kind of a kind of precoated metal plate that overcomes the above problems is provided to the deficiency of the laser cutting parameter existence of the precoated metal plate of prior art.
To achieve these goals, the technical scheme of the present invention's employing is:
A kind of laser cutting parameter of precoated metal plate comprises following processing step:
(1), the metal film coated metallic plate that placement need be cut on the laser board;
(2), burn film: the protective gas tube connector that will connect the cutting head place connects compressed air; Cutting head is adjusted to the distance from precoated metal plate 5-15cm; Cutting power is adjusted to the low power state of 100-200W, and cutting head is along needing the path of cut workpiece to move, under the compressed air effect; Burn the surface coating of the path locus that the precoated metal plate need cut, form the burning film track of 1-2.5mm width;
(3), cutting: after burning the film completion; The protective gas tube connector that connects the cutting head place is connected to protective gas; Cutting power is adjusted to the power of normal cutting metal plate and suitable cutting head height, carries out cut along burning the film track, cuts into required workpiece.
Said step 2 cutting head is adjusted to the distance from precoated metal plate 10cm.
Cutting power is adjusted to the low power state of 150W in the said step 2.
Beneficial effect of the present invention is: the laser cutting parameter of a kind of precoated metal plate of the present invention, technology of the present invention comprise, (1), the metal film coated metallic plate that placement need be cut on the laser board; (2), burn film: under the compressed air effect, burn the surface coating of the path locus that the precoated metal plate need cut, form the burning film track of 1-2.5mm width; (3), carry out cut, cut into required workpiece along burning the film track; Form and behind the burning film track on the cutting path, carry out normal cutting technique through burning film, diaphragm forms metal film coated plate displacement that " bulge " cause at metal sheet surface, causes misplacing at the cutting route on the metallic plate, seriously causes under the situation generation of problems such as scrapping when avoiding the cutting of traditional metal film coated plate; And because the cutting slag follows the plastic foil slag to splash, form anti-slag when avoiding the tradition cutting, influence the generation of the cosmetic issue of film coated plate on the film coated plate surface; Reduce product rejection rate, improve product surface quality.
The specific embodiment:
Below in conjunction with embodiment the present invention is further described:
A kind of laser cutting parameter of precoated metal plate comprises following processing step:
(1), the metal film coated metallic plate that placement need be cut on the laser board;
(2), burn film: the protective gas tube connector that will connect the cutting head place connects compressed air; Cutting head is adjusted to the distance from precoated metal plate 5-15cm, and cutting power is adjusted to the low power state of 100-200W, and cutting head is along needing the path of cut workpiece to move; Under the compressed air effect; Under the laser cutting nozzle high temperature action, plastic foil burning when compressed air provides oxygen, high pressure air also blows the ashes that burning generates off; Burn the surface coating of the path locus that the precoated metal plate need cut, form the burning film track of 1-2.5mm width;
(3), cutting: after burning the film completion; The protective gas tube connector that connects the cutting head place is connected to protective gas; Cutting power is adjusted to the power of normal cutting metal plate and suitable cutting head height, carries out cut along burning the film track, cuts into required workpiece.
As preferred embodiment, step 2 cutting head is adjusted to the distance from precoated metal plate 10cm, under general low-power cutting power situation, can both burn film preferably.
As preferred embodiment, step 2 cutting power is adjusted to the low power state of 150W, can both burn film preferably.
The laser cutting parameter of a kind of precoated metal plate of the present invention, technology of the present invention comprise, (1), the metal film coated metallic plate that placement need be cut on the laser board; (2), burn film: under the compressed air effect, burn the surface coating of the path locus that the precoated metal plate need cut, form the burning film track of 1-2.5mm width; (3), carry out cut, cut into required workpiece along burning the film track; Form and behind the burning film track on the cutting path, carry out normal cutting technique through burning film, diaphragm forms metal film coated plate displacement that " bulge " cause at metal sheet surface, causes misplacing at the cutting route on the metallic plate, seriously causes under the situation generation of problems such as scrapping when avoiding the cutting of traditional metal film coated plate; And because the cutting slag follows the plastic foil slag to splash, form anti-slag when avoiding the tradition cutting, influence the generation of the cosmetic issue of film coated plate on the film coated plate surface; Reduce product rejection rate, improve product surface quality.
