Open material equipment in the present embodiment and carry out work according to the material working process parameter of opening of setting in advance.When substantially opening the startup of material system, opening in the present embodiment expects that controller 1 is according to the R type transformer core specification of processing, launch to calculate out with trimming algorithm the theoretical value of material curve by the R shaped iron core, when open the material controller 1 detect each mechanism's preliminary work of cutting machine ready after, just can directly start work.Whole work is divided into two stages: the phase one is reseting stage, it mainly is the reference position of determining strip processing, the zero clearing of linear transducer counting, first drives material cutter 7, second drives material cutter 8 and moves to the initial width position of strip curve place, ready for normally opening the material processing work; Subordinate phase is that normalized curve is opened the material process segment, this stage course of work is: after having processed machine during first iron core curve strip, launch to calculate with trimming algorithm the theoretical curve of curve strip according to the R shaped iron core, and by opening material controller 1 generation strip 1 bent material 12, the bent material 13 of strip 2 open the material curve data, generate the width data table that can be used for open material processing strip curve corresponding with the strip length information according to opening material curve interpolation algorithm again, open to expect to add and open the length information that material controller 1 detects according to linear transducer 6 man-hour, directly read strip width data table and obtain the bent material 12 of the first strip, the strip curve width data of the bent material 13 of the second strip, then convert the first servomotor 32 to through calculating, the angle information of the second servomotor 36 rotations, again according to servocontrol electric cam function, with the first servomotor 32, the second servomotor 36 rotary angle position convert pulse information to and directly export to the first motor servo driver 33, the second motor servo driver 37, then directly drive the first servomotor 32, the second servomotor 36, by opening material the first translation mechanism 31, the first translation mechanism 35 rotatablely moves motor and is transformed to the horizontal rectilinear motion of process tool, drive first and drive material cutter 7, second drives material cutter 8 moves to the required width position of strip place, opens the material process thereby finish an iron core strip.
In system, can find out, the first servomotor 32, the 36 angular movement controls of the second servomotor own can realize closed-loop control, but first drives material cutter 7, second drives material cutter 8 and the first servomotor 32, pass through mechanical transmission mechanism the first knife rest translation mechanism 31 between the second servomotor 36, the second knife rest translation mechanism 35 connects, therefore mechanical cumulative errors can be brought in the mechanical driving device gap, first drives material cutter 7, second opens the translational movement (actual strip width) and the first servomotor 32 of material cutter 8, there is certain error in rotatablely moving of the second servomotor 36 between (molded breadth information), that is to say, prior art can not compensate because the strip mismachining tolerance that mechanical driving device brings is that a strip curve is opened material processing open cycle system in essence.For this reason, by the first back light 9, the second back light 15, provide imaging source for obtaining the strip image in the present embodiment; By the first industrial camera camera lens 10, the second industrial camera camera lens 14, finish the imaging of curve strip, provide original image signal for obtaining the strip width information; Finish the image of strip width measure processes by image processing system 1, obtain the width data of strip, and by RS-485 bus 18 send to out the material controller 1, record all strip curve width datas in such strip length process-cycle, and compared with the last material curve data opened of material in the process-cycle of opening, and suitably revise, thereby generate new opening and expect curve width data table, call (alternative aforesaid subordinate phase normalized curve is opened opening in the material process segment and expected processing strip curve width data table) during for the next strip of processing, thereby realize opening material curve width dynamic compensation, by that analogy, go round and begin again, to guarantee and to improve transformer core and open the material crudy.
Present embodiment by experiment method verifies that verification environment is: double material strips is cut out a piece of cloth in a way with the minimum material to make two or more articles of clothing processing cutting machine (max. speed 120m/min).Fig. 2, Figure 3 shows that above-described embodiment test design sketch.Present embodiment can be opened on-line setup compensating parameter in the material process at R type transformer core, to adapt to the needs of different product processing; And in opening the material process, can show online strip actual curve and data, by checking compensation effect, in time adjust and open the material technological parameter, improve R type transformer core and open the material machining precision, reduce the product rejection rate, greatly enhance productivity.
