Abstract
The invention relates to a laser beam cutting and perforating apparatus, which is arranged on the upper portion of a workpiece and connects to a control apparatus. This control apparatus comprises a zooming device which can spot the laser focus position and a pulse device which can change laser apparatus's laser frequency and duty cycle. This apparatus has high perforating benefit and can get holes with smaller diameter [diameters.
Description
Technical field
The present invention relates to a kind of laser beam cutting punching machine.
Background technology
Cutting perforation is the important prerequisite that guarantees the cut effect, and following three kinds of method for punching are generally arranged: 1) explosion perforation: workpiece through after the irradiation of continuous laser in be formed centrally a pit, until penetrating.The explosion piercing aperture is big, it is also big to splash; 2) pulse punching: change frequency, the dutycycle of laser beam during perforation simultaneously, can obtain the perforation of smaller aperture due; 3) zoom perforation: adopt the high frequency lasers perforation, the focal position of laser is also downward gradually in the perforation procedure, makes the high-energy light beam be in not penetration site always, the perforation high efficiency.
Summary of the invention
It is a kind of with the above-mentioned laser beam that above-mentioned three kinds of perforation means advantages are integrated cutting punching machine that the object of the invention is to provide.
Technical scheme of the present invention is: the present invention is arranged on the top of workpiece, and it connects a control device, and this control device comprises the zoom lens control device that makes focal position in the laser aid, changes the pulser of laser aid laser frequency, dutycycle.
Advantage of the present invention is: this practicality newly has the perforation high efficiency, can obtain the perforation effect of smaller aperture due.
Description of drawings
Fig. 1 is a structural representation of the present invention
1 is that focusing lens, 2 is workpiece among the figure.
The specific embodiment
The present invention is arranged on the top of workpiece 2, adopts the high frequency lasers perforation, and the position of focusing lens 1 changes in the perforation procedure, and the focal position of laser is also downward gradually, makes the high-energy light beam be in not penetration site always, the perforation high efficiency.
The present invention simultaneously changes frequency, the dutycycle of laser beam simultaneously when boring a hole, can obtain the perforation of smaller aperture due.
Claims (1)
1. laser beam cuts punching machine, is arranged on the top of workpiece, it is characterized in that it connects a control device, and this control device comprises the zoom lens control device that makes focal position in the laser aid, changes the pulser of laser aid laser frequency, dutycycle.
