The turning machine 10 generally includes a bed 11, a conveying rail 12 provided on the bed 11, a tailstock 13 located at both ends of the conveying rail 12, And the roll mold 20 is rotated and processed while being fixed so as to extend in the first direction X between the tailstock 13 and the main shaft 14.

In this case, the multi-cutting processing module 100 according to this embodiment is transported in the first direction X on the feed rail 12 and processes the roll mold 20. Since the general configuration of the turning machine 10 is a well-known technology, the multi-cutting processing module 100 and the multi-cutting machining method using the multi-cutting machining module 100 will be described in detail below.

2 is a perspective view showing the multi-cutting machining module of FIG. 1;

2, the multi-cutting processing module 100 includes a base 110 fixed on the feed rail 12 and being transported in the first direction X, A guide part 120 extending in a second direction Y perpendicular to the first direction X and a sliding part 130 guided by the guide part 120 and being transported in the second direction Y, And a tool unit (200) fixed on the sliding part (130) and processing the roll mold (20).

The tool unit 200 includes a jig 210 fixed on the sliding portion 130 and formed in a U shape, a magnet 220 disposed on a side of the inner space of the jig 210, An encoder 230 extending on the outer surface of the jig 210 in the first direction X and a plurality of tool holders 210 guided by the jig 210 and provided on the jig 210, A driving unit 250 driving the tool holders 260 in the first direction X, tools 300 fixed by the tool holders 260, 260) for adjusting the projecting position of each of the tools (300) in the second direction (Y), and an adjusting unit (270) extending from the rear end of each of the tool holders And a sensor unit 240 positioned on the encoder 230 and sensing the position of each of the tool holders 260.

Thus, the tool unit 200 is transferred integrally in the first direction X and the second direction Y, and each of the tools 300 is individually driven by the driving unit 250, And the protruding position in the second direction Y can be adjusted by the adjustment unit 270 individually or in the direction X. [

Fig. 3 is a plan view showing the tool arrangement of the multi-cutting machining module of Fig. 2; Fig.

Referring to FIG. 3, the tool 300 of the multi-cutting machining module 100 according to the present embodiment includes a plurality of tools, and as shown in the drawing, for example, Third to third tools 310, 320, and 330. As shown in FIG.

In this case, the respective tools are spaced apart from each other by an integral multiple N (hereinafter referred to as a first distance) of the machining pitch in the machining of the roll mold, as shown.

Further, the respective tools are protruded by the same length in the direction in which the roll mold 20 is positioned, and the tips of the tools are positioned on the same line as shown in the figure.

Meanwhile, the first to third tools 310, 320, and 330 may include bytes of the same size to perform the roughing process simultaneously with the roll metal mold 20, Or finishing simultaneously.

Alternatively, the first to third tools 310, 320 and 330 may include bytes having different sizes, the third tool 330 may be rough machined, the second tool 320 may be rough machined The first tool 310 may perform a finishing process. After the roughing process is performed on the roll mold 20 by the third tool 330, the second tool 320 and the first tool 310 are then subjected to roughing and finishing operations respectively .

As described above, in the present embodiment, since the first to third tools 310, 320, and 330 simultaneously process the roll mold 20, not only the machining time can be saved, It is possible to omit the necessity of changing the bite at the time of finishing, and more effective processing becomes possible.

Fig. 4 is a schematic diagram showing an example of a processing pattern for machining a roll mold using the tool arrangement of the multi-cutting processing module of Fig. 3; Fig.

4, when the roll mold 20 is machined through the tool 300 of the multi-cutting machining module 100, each of the first to third tools 310, 320, 1 to the third positions P, Q and R, respectively.

If all of the first to third tools 310, 320, and 330 are simultaneously subjected to roughing, medium cutting, or finishing, the first to third tools 310, 320, 330 perform machining on the roll mold 20 until reaching the position of the adjacent tool, that is, until the machining is performed by the first distance, and then after machining by the first distance , The tool is simultaneously moved from the first to third positions (P, Q, R) by three times of the first distance (N times if the tool is N because the tool is three) do.

Accordingly, when all of the first to third tools 310, 320, and 330 simultaneously perform the roughing, the medium cutting, or the finishing, the roll mold 20 is processed using one tool , The machining time is reduced by 1/3.

If the first to third tools 310, 320, and 330 perform the finishing, the medium cutting, and the roughing, respectively, the first to third tools 310, 320, ) And processed continuously.

When each of the first to third tools 310, 320, and 330 separately performs finishing, centering, and roughing, the machining time is reduced by one third and the time for exchanging the bytes.

On the other hand, in the example of the present processing pattern, a processing pattern is intermittently formed on the roll metal mold 20, and the intermittently formed processing pattern is formed to be spaced apart from the pitch of the roll metal mold 20 .

Fig. 5 is a schematic diagram showing another example of a machining pattern for machining a roll mold using the tool arrangement of the multi-cut machining module of Fig. 3; Fig.

5, when the roll mold 20 is machined through the tool 300 of the multi-cutting machining module 100, each of the first to third tools 310, 320, 1 to the third positions P ', Q', and R ', respectively.

In this example of the processing pattern, the processing pattern is continuously formed on the roll metal mold 20, and the processing pattern continuously formed is spaced by the transfer pitch of the roll metal mold 20. Accordingly, the first to third tools 310, 320, and 330 may continuously process the roll mold 20 when the processing is performed by the first distance.

However, if the first to third tools 310, 320, and 330 are to perform only one of the roughing, the medium cutting, and the finishing, as described above, the machining is performed by the first distance, After being transported by three times the first distance, machining is carried out again and again.

Alternatively, if the first to third tools 310, 320, and 330 individually perform the finishing, the medium cutting, and the roughing, respectively, the first to third tools 310, 320, The process is continuously performed up to the end of the roll metal mold 20, except for the case of replacing with abrasion of a byte or the like.

For example, as shown, the first tool 410 may protrude a greater distance a than the second tool 420, and the second tool 420 may protrude from the third tool 430 ) By a second distance b.

Thus, the first tool 410 may be used for finishing, the second tool 420 may be used for medium cutting, and the third tool 430 may be used for roughing.

4 and 5, when the roll mold 20 is machined by using the tool 400 according to the present embodiment, it is possible to prevent the roll mold 20 from being deformed, The roll mold 20 may be intermittently fed while being simultaneously fed by the machining pitch of the roll mold 20, or the roll mold 20 may be continuously machined.

However, since the first to third tools 410, 420, and 430 are used only for finishing, medium cutting, and roughing, respectively, it is unnecessary to move the tool by three times the first distance, It is possible to transfer only the machining pitch from one end to the other end of the roll metal mold 20 or to continuously perform the machining.
