The step punch system of the heavy plate during laser cutting comprises a cutting nozzle and a laser cutting machine connected with the cutting nozzle and further comprises a plurality of timing units and a plurality of comparison modules which correspond to the timing units and are pre-stored with standard operation parameters, wherein the laser cutting machine is connected with a controller used for controlling cutting intensity of the laser cutting machine, each timing unit is connected with a corresponding comparison module, an output end of the controller is connected with an input end signal of the comparison module, and an output end of the comparison module is connected with an input end signal of the controller. When the step punch system is at work, main parameters generate step change within punch time according to certain rules, so best parameter coupling is realized; punch time and local overheating are avoided; a blasting hole ratio is reduced; and damage to a focusing mirror is avoided, and thereby penetration of a fine small hole can be realized within relatively short time.
Description
Technical field
The utility model relates to a kind of perforation system of cut cut deal.
Background technology
Adopt the perforation system of existing cut cut deal, control the work of laser cutting machine by controller.Because sheet material is thicker, the perforation of employing normal pulsed, the aperture time is often very long, and also since local behind long-time laser beam irradiation, be easy to cause solution to splash at punch position and become large with piercing aperture, be i.e. blast hole.Can cause so the initial difficulty of cutting, and cause the focusing lens damage because solution splashes.
Summary of the invention
Above-mentioned deficiency for the perforation system that overcomes the cut cut deal, the utility model provides a kind of principal parameter to carry out continuous step variation according to certain rule within the aperture time, thereby the parameter matching with optimum, make it to reduce the aperture time, avoid local overheating, and reduce the blast hole rate, avoid damaging focus lamp, thereby finish the step perforation system of the cut cut deal that penetrates of meticulous aperture in the short period.
The technical scheme in the invention for solving the technical problem is: a kind of step perforation system of cut cut deal, comprise cutting head and the laser cutting machine that is connected with described cutting head, described laser cutting machine is connected with the controller that is used for its cutting intensity of control, comprise that also several timing units and several corresponding with timing unit prestore the comparison module of standard operation parameter, the comparison module connection that each timing unit is corresponding with it; The output terminal of described controller is connected with the input end signal of described comparison module, and the output terminal of described comparison module is connected with the input end signal of described controller.
Further, described comparison module also is connected with input media.
Further, described input media is keyboard.Perhaps, described input media is touch-screen.
The utility model at first, is set aperture time T in use, sets the step frequency n, and after n set, then the time of single step was T/n, and the variable of namely boring a hole all jumps with this snap time T/n, and the step frequency n is the quantity of timing unit very.
Set the perforation condition: the laser power that namely in comparing unit, prestores, pulsed frequency, pulse duty factor, perforation air pressure, these standard operation parameter values of perforation height, in each snap time section, controller is transferred to comparison module with parameter value individual operating parameter is compared, and actual operational parameters must not surpass the limit value of setting.
The persistent value of each snap time is controlled by timing unit during work, and each timing unit timing finishes then this snap time section end.
Set starting condition: in the starting condition, parameter equivalent value when power, frequency dutycycle, air pressure, perforation highly then are initial perforation, in this parameter, power, frequency dutycycle must not be less than perforation condition setting values, be that power, frequency dutycycle are by little and large, reduce the blast hole rate of initial perforated; Air pressure, perforation highly then are to reduce gradually, finally are reduced to the perforation setting value.
In various variable conditions were set, the step number of times was larger, and it is less that various conditions change equivalent, and the step maximum times limits 20 times.Perforation height step descends, and the focal length of then boring a hole is from top to down change and then, and energy strengthens with focal length; Perforation centre gaseous tension also strengthens with highly descending, but because external control air pressure is a process of successively decreasing, therefore in fact offset because of perforation highly the air pressure that brings of decline excessive, cause the origin cause of formation of blast hole easily.
The beneficial effects of the utility model are: principal parameter is carried out continuous step according to certain rule and is changed within the aperture time, thereby the parameter matching with optimum, make it to reduce the aperture time, avoid local overheating, and minimizing blast hole rate, avoid damaging focus lamp, thereby finish penetrating of meticulous aperture in the short period.
