BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to cutting and machining methods of a cutting blade, and more particularly, to a cutting and machining method of a cutting blade capable of effectively preventing an edge portion of a cutting blade from being bent during cutting of the cutting blade.

The cutting blade applied to the die cutting is usually formed long in a thin strip shape. Accordingly, the cutting blade is cut and used to a required length by a cutting device. However, when the cutting blade is cut at a time, a large force is applied to the cutting blade, so that the edge portion C positioned at the upper end and forming the blade easily bends during cutting as shown in Fig. However, when the edge portion C is warped, there is a problem that it is difficult for the cutting blade to precisely process the workpiece in a machining process such as die cutting.

SUMMARY OF THE INVENTION It is therefore an object of the present invention to provide a method of cutting and machining a cutting blade capable of effectively preventing the edge portion of a cutting blade from being bent during cutting of the cutting blade.

A method of cutting a cutting blade according to the present invention comprises the steps of preparing a cutting blade having a band-like body and an edge extending upward from the body and forming an edge, a cutting blade cutting edge at a predetermined position to cut the cutting blade, A cutting step of cutting the part, a feeding step of feeding the cutting blade after the cutting step, and a cutting step of cutting the cutting blade by cutting the lower part of the edge part after the feeding step.

Further, a method of working a cutting blade according to the present invention is characterized by including a step of preparing a cutting blade, a cutting step of cutting the upper part of the cutting blade at a predetermined position to cut the cutting blade, a cutting step of cutting the cutting blade at a predetermined position And a cutting step of cutting the lower portion of the upper portion to cut the cutting blade after the bending step. Wherein the cutting blade may have a band-like body and an edge extending upwardly from the body to form a blade, and the cutting step may cut the edge portion located in the upper portion of the cutting blade.

The cutting and cutting method of the cutting blade according to the present invention has an effect of preventing the edge portion from being bent when cutting the cutting blade because the edge portion of the cutting blade is cut before cutting the cutting blade.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. However, the present invention is not limited or limited by the following examples.

Example 1

The cutting method according to the first embodiment of the present invention relates to a method of cutting a cutting blade. As shown in Fig. 1, basically the preparation step (S101), the cutting step (S102), the feeding step (S103) And a cutting step S104. 1 is a flowchart showing a cutting method according to the first embodiment of the present invention.

First, the preparation step (S101) will be described. The preparation step (S101) is a step of preparing the cutting blade (110). The cutting blade 110 is typically used for die cutting. The cutting blade 110 is formed in a long strip shape. More specifically, the cutting blade 110 has a band-shaped body 111 and an edge 112 extending upward from the body 111 to form a blade, as shown in FIG. 2 is a perspective view showing a cutting blade applied to the cutting method of FIG. For reference, the cutting blades 110 are generally continuously fed in a rolled state.

Next, the cutting step (S102) will be described. The cutting step S102 is a step of cutting the upper portion of the cutting blade 110 at a predetermined position. Wherein the upper portion includes an edge portion 112 located in the upper portion of the cutting blade 110. That is, the cutting step S102 is a step of cutting the edge portion 112 at a predetermined position to cut the cutting blade 110, as shown in Fig. Of course, cutting can be done below the edge portion. Alternatively, only the end of the edge portion may be cut. Since it is important that the edge of the edge corresponding to the edge of the edge portion is not bent, it is necessary to cut at least the edge of the edge portion.

Cutting the edge portion 112 of the cutting blade 110 in this manner prior to cutting the cutting blade 110 may prevent the edge portion 112 from bending when cutting the cutting blade 110. When the cutting blade 110 is cut at one time, a large force is applied to the cutting blade 110. The edge portion 112 located at the upper end is liable to be bent during cutting. However, if the edge portion 112 is warped, it is difficult for the cutting blade 110 to accurately process a workpiece in a machining process such as die cutting. However, if the edge portion 112 is first cut as in the present embodiment and then the lower portion of the edge portion 112 is cut in the cutting step S104 (to be described later), a relatively smaller force is applied first to the edge portion 112, It is possible to prevent the edge portion 112 from being bent when the remaining portion is cut.

This is more effective when cutting the edge portion 112 with a cutting member that cuts the cutting blade 110 by rotation. 3, when cutting the edge portion 112 of the cutting blade 110 with the cutting member 121 of the cutting device 120, the edge portion 112 is instantaneously forced to rotate by the rotation of the cutting member 121. As a result, So that the edge portion 112 may not warp during cutting. This is more effective when the cutting member 121 is a grinding wheel. This is because the grinding wheel hardly pushes the edge portion 112 in the thickness direction of the cutting blade 110 during cutting. 3 is a perspective view showing a cutting apparatus applied to the cutting step of the cutting method of FIG.

However, it is possible to consider machining the upper portion of the cutting blade into a specific shape through punching. However, if the cutting blade is not properly supported during punching, the edge portion of the cutting blade can be strongly pushed in the thickness direction of the cutting blade by punching. In this case, even if the lower portion of the cutting blade is cut after punching, there is a high possibility that the edge portion has already been bent by punching. Therefore, it is preferable to cut the edge portion with the aforementioned cutting member.

On the other hand, as shown in FIG. 4, the two cutting blades 110a and 110b can be coupled to each other in a T-shape. For such a coupling, the edge portion 112 may be sloped inwardly from the top to the bottom as shown in Fig. Here, the inner side refers to the direction toward the remaining portion even after cutting. This cutting can be performed by cutting the upper portion of the cutting blade 110 into the cutting shape of FIG. When the remaining portion (see the dotted line portion in FIG. 5) is cut in the cutting step (S104) to be described later after such cutting, a cutting blade capable of T-like joining like the cutting blade 110b of FIG. 4 can be obtained . For reference, the cutting blade 110b of FIG. 4 can be joined in various shapes as well as a T-shape.

Next, the transfer step S103 will be described. The transferring step S103 is a step of transferring the cutting blade 110 after the cutting step S102. The cutting method according to the present embodiment first cuts the upper portion of the cutting blade 110 and then cuts the remaining portion of the cutting blade 110 in order to cut the cutting blade 110. [ For this purpose, a cutting device may be provided above the cutting blade 110 and a cutting device may be provided below the cutting blade 110 at the same position.

However, this may cause interference between devices. Therefore, it is desirable that the cutting device and the cutting device are installed at different positions. To this end, the cutting method according to the present embodiment includes a feeding step (S103) for feeding the cutting blade 110. By this transfer, the cutting device and the cutting device can be installed at different positions. The cutting blade 110 may be bent after the feeding as described above in the second embodiment.

Next, the cutting step (S104) will be described. The cutting step S104 is a step of cutting the cutting blade 110 by cutting the lower portion of the edge portion 112 after the feeding step S103. That is, the cutting step S104 is a step of cutting the cutting blade 110 by cutting the remaining portion indicated by a dotted line in FIG. 6 after the upper portion is cut. 7, the cutting blade 110 is pressed by the cutting member 132 while the cutting blade 110 is supported by the support member 131 to cut the lower portion of the upper portion, (130). Alternatively, the lower portion of the upper portion may be cut with the cutting member to cut the lower portion. Through the cutting step S104, the cutting blade 110 can be cut at a predetermined position.

For reference, it may be preferable that the lower portion of the upper portion is cut at the cutting step (S102) by more than the cutting width of the upper portion. For example, in the T-shaped engagement described above with reference to FIGS. 4 and 5, if the body portion 111 protrudes outwardly than the edge portion 112, The edge portions 112 in the blades 110 may be spaced apart from each other after engagement. However, if the lower portion is cut more than the upper portion, the body portion 111 does not protrude outward beyond the edge portion 112, so that the body portion 111 can prevent the edge portions 112 from being separated from each other.

Example 2

The method of working according to the second embodiment of the present invention relates to a method of machining a cutting blade, and basically includes a preparing step S201, a cutting step S202, a bending step S203, And a cutting step S204. 8 is a flowchart showing a processing method according to the second embodiment of the present invention. The machining method according to the present embodiment differs in the cutting method and the bending step according to the first embodiment, and will be mainly described below.

The machining method according to this embodiment performs the bending step S203 after the preparation step S201 and the cutting step S202. The bending step S203 is a step of bending the cutting blade 110 at a predetermined position. For example, as shown in FIG. 9, the cutting blade 110 can be bent at a predetermined angle from a predetermined position. Such bending may be done multiple times at various locations. And a conveying step for conveying the cutting blade 110 after the cutting step S202 may be performed for such bending.

The bending step S203 may be performed in the bending device 140 of Fig. That is, in a state in which the cutting blade 110 is supported by the support body 141, the cutting blade 110 may be pressed by the pressing body 142 rotating around the support body 141 to bend the cutting blade 110 .

For reference, the bending step S203 in this embodiment may be performed before the cutting step S202. For example, the bending device, the cutting device, and the cutting device may be positioned in order based on the feeding direction of the cutting blade. Of course, the cutting device, the bending device, and the cutting device may be positioned in order based on the feeding direction of the cutting blade. Alternatively, the necessary steps may be performed by moving the cutting blades in the desired sequence, irrespective of the order in which they are installed. However, after the cutting step (S202) and the bending step (S203) are both performed, the cutting step (S204) is performed.
