EXAMPLE III
In this embodiment, the frame 1, the first cutting roller 2, the second cutting roller 3, the tensioning device 5, the workbench device 6, the cutting fluid supply system 7 and the annular diamond wire 8 are arranged in the same manner as in the second embodiment.
The difference lies in, the high-speed many rings of numerical control cutting device in this embodiment includes 6 wire winding running roller 4, wire winding running roller 4 except fixed with cutting running roller 2 and two 3 matches of cutting running roller, and set up on overspeed device tensioner 5 outside, 2 wire winding running roller 4 sets up the cutting running roller 2 and the two 3 side positions of cutting running roller at 1 front panel in frame for make the annular diamond line 8 between cutting running roller 2 and the cutting running roller 3 keep the state of opening one's way, ensure many annular diamond lines 8 under the tensioning state synchronous rotation.
1 wire winding running roller 4 sets up in 1 front panel below of frame for increase 8 girths of annular diamond wire, so that make annular diamond wire 8 can select suitable length according to the material and the size of work piece 9, and then improve machining precision and 8 utilization ratios of annular diamond wire.
The longer the line length L of the annular diamond line 8, the longer its service life; however, the longer the wire length L of the annular diamond wire 8, the larger the number of the winding rollers, the larger the occupied space, and in order to select a reasonable sawing process, the annular diamond wire with a proper length needs to be selected.
The process test shows that: l = number of saw cuts x amount of single wire consumption.
The single wire consumption is a sawing process value, and the sawing process values of different materials and different specifications and sizes are different.
In the present embodiment, the single consumable-wire amount of the workpiece to be processed is generally not more than 2 meters. And the sawing frequency is determined by the yield requirement of the required product, the annular line with reasonable length can be selected according to different yield requirements, the cost of the annular line is saved, and the number of the winding rollers is saved. Therefore, the cutting device basically uses the annular diamond wire 8 having a length of 2 to 10 meters.

As shown in fig. 3, the difference between the first embodiment and the third embodiment of the present invention is that the numerical control high-speed multi-ring cutting device further includes an infrared temperature measurement module, and the infrared temperature measurement module includes an infrared image acquisition device 10 and an image processing unit. When the annular diamond wire 8 is heated to about 700 ℃ in the air, the problems of oxidation weight loss and reduction of pressure resistance begin to occur, so that the damage of equipment caused by the fact that the annular diamond wire 8 reaches the critical temperature is avoided.
Wherein, the infrared image acquisition device 10 is arranged above the machine frame 1 between the first cutting roller 2 and the second cutting roller 3; the infrared image acquisition device 10 is used for acquiring an infrared image of the annular diamond wire 8 between the first cutting roller 2 and the second cutting roller 3 in a overlooking mode.
The image processing unit judges the temperature of the annular diamond wire 8 by identifying the annular diamond wire 8 in the infrared image and the image pixel value (or brightness value) of the annular diamond wire 8, establishes the corresponding relation between the pixel value of the local bright point in the image, such as an RGB color value, and a standard temperature material, converts the pixel value of the local bright point in the infrared image into a corresponding temperature value based on the corresponding relation, sets an alarm threshold value for the pixel value of the infrared image, and gives an alarm when the R value exceeds a certain value. Specifically, the image processing unit processes the infrared image, extracts pixel regions which are arranged in a long straight shape and have high-temperature pixel values, and regards the pixel region formed by the pixel points as a pixel corresponding to the annular diamond wire 8; and the pixel value corresponding to the annular diamond wire 8 is continuously monitored, so that the normal working temperature of the annular diamond wire 8 is avoided being exceeded.
When the image processing unit finds that the temperature of the annular diamond wire 8 is close to the maximum value of the working temperature, the cooling liquid flow is increased, the temperature of the annular diamond wire 8 is controlled at the working temperature, and if the cooling liquid flow is increased, the temperature of the annular diamond wire 8 cannot be controlled, the rotating speed of the annular diamond wire 8 is reduced or the annular diamond wire is stopped by alarming, so that the temperature of the annular diamond wire 8 is controlled within the working temperature range.
The too high temperature of annular diamond wire 8 probably has multiple reasons, probably because the deviation between the spraying position of coolant liquid and the cutting position leads to, also probably because there is the particularity to lead to by the cutting material, also probably because the local loss of annular diamond wire 8 leads to too seriously, through the mode of this embodiment, just can in time discover the problem of annular diamond wire 8 in the cutting process, avoid bringing unnecessary loss to the polycyclic cutting device, can reduce the work piece damage, improve the yield.
EXAMPLE five

Particularly, in the whole implementation process, the annular diamond wires 8 rotate in an infinite cycle at a high speed in one direction, the annular diamond wires 8 are not crossed and do not interfere with each other, the abrasion consistency of the annular grooves and the abrasion consistency of the annular diamond wires 8 are ensured, and the consistency of the whole plate processing precision of each workpiece is ensured. Because the 8 groups of the annular diamond wires have only one acceleration and deceleration process in the whole process and the pause phenomenon of pause and return in the cutting process is avoided, the workpiece 9 is cut in the same direction at the same speed from top to bottom, the processing precision of a single piece in the whole workpiece plate from top to bottom is further controlled, and the micron-sized or even higher processing precision is realized.
The linear speed of the high-speed annular diamond wire 8 reaches 50-100 m/s or more, the wire diameter error of the annular diamond wire 8 is only a few micrometers, the length of the annular diamond wire is within the range of 2-10 m, the wire diameters of the positions participating in workpiece processing in the high-speed wire running process are within the range of the wire diameter error profile, and the wire diameter error profile can be equal to that of a constant-diameter annular wire for grinding and sawing the workpiece, so that the sawing seams are uniform and constant in width, and the precision sawing is ensured. In addition, the feeding speed and the feeding position of the workbench are controlled by a precise servo motor, and the precision is in the micron level, so that the precise sawing of the curved surface is realized.
