The cutting tool 10 of the present invention is installed on an automatic cutting device (not shown) for cutting the material into a plurality of webs 30, and the automatic cutting device comprises a cutting tool for the cutting tool. 10 set cutting area 20, and a feeding device for continuously feeding the material along a feeding path R to the cutting area 20, the cutting area 20 comprising a first side cutting block 21, and A second side cutting block 22, the material and the web 30 have a first side 31 and a second side 32 corresponding to both sides of the feeding path R direction.

As shown in FIG. 1 and FIG. 2, the cutting tool 10 includes a first tool 11 and a second tool 12, which are mechanically transmitted through the power provided by the automatic cutting device. The first cutter 11 or the second cutter 12 moves the cutting to complete the cutting action. The mechanical principle refers to a combination of one or more mechanisms, and the work generated by the energy source drives the plurality of mechanisms to act on each other to promote mechanical energy to operate for the desired purpose. As a clear illustration, the first tool 11 / the second tool 12 can be driven by the electromagnetic and magnetic motor to drive the gear. However, the aspect described is only for one of the embodiments, and is not used. To limit the scope of this creation.

The first cutter 11 has two first dies 111a and a second dies 111b, and the first dies 111a correspond to the first side cutting block 21, The second die 111b corresponds to the second side trimming block 22. In this embodiment, the second cutter 12 is normally fixed under the cutting region 20, and the first cutter 11 and the second cutter 12 are driven to close each other to complete the cutting. The term "symmetry" as used in the present application means that the direction of the slits of the first die 111a and the second die 111b are opposite, so that the two rounded corners of the front segment are cut in two stages. The two rounded corners of the rear section are close to the inner edge of the cutting edge of the first die and the second die, and the outer edges of the two sides are open-ended openings, so that the cutter is slightly "work" shaped. Therefore, the shapes of the first die 111a and the second die 111b do not have to be exactly the same, and within a reasonable error value range, or one of the die shapes is formed for the partial shape of the chip to generate another blade. Different designs should still fall into the definition of "symmetry" in this creation.

The first die 111a and the second die 111b include a cut-off side 113a, 113b adjacent to the inner edge of the first tool, and are disposed on the two sides of the cut-off side 113a, 113b, respectively, according to the cutting requirements. a reference side 112a, 112b and a trimming side 114a, 114b, the reference side 112a, 112b and the cutting side 113a, 113b have a first rounded corner 115a, 115b, the trimming side and the cutting side The intermediate system has a second fillet 116a, 116b.

There should be a suitable gap between the first side 31 and the first side 31 to avoid the situation in which the reference side 112a, 112b stops operating due to unclean material when the material is broken. In addition, the angle between the cutting sides 113a, 113b and the trimming sides 114a, 114b is an obtuse angle design, more specifically, the cutting side The angle between the 113a, 113b and the trimming side 114a, 114b is between 90 degrees and 180 degrees (ie, an obtuse angle), and the angle is defined as the second rounded corner 116a, 116b. In this embodiment, the angle is The trimming sides 114a, 114b extend from the second fillet 116a, 116b and are inclined to the cut side 113a, 113b, so that when the cutting tool 10 is cut, a first tool is generated 11 and a margin space 117a, 117b between the first side 31 of the material, thereby eliminating tolerances to avoid the material material shifting along the sides of the feeding path R due to the lateral force during the transfer, resulting in the material The machine stopped working due to failure to align with the unclean material during cutting.

Referring to FIG. 3, the second cutter 12 can be divided into a first blade 121a corresponding to the first die 111a and a second blade 121b corresponding to the second die 111b. The first blade edge 121a and the second blade edge 121b have a design in which the protruding portions 123a, 123b are inclined to the sides at the middle point of the blade edge (if the blade edge section is made straight, the cutting section of the material material is too long, The force is dispersed. The design of the protrusions 123a, 123b enables the material to be preferentially stressed by the protrusions 123a, 123b during the cutting process, and is cut by a single point and cut along the sides in a manner similar to scissors. , you can concentrate the material on all parts of the force. As shown in FIGS. 5-1, 5-2, and 5-3, the first blade edge 121a and the bottom of the second blade edge 121b respectively have a yield space 122a, 122b for the purpose of cutting. The material can be smoothly detached through the space, and the remaining waste scraping is prevented from affecting the cutting operation in the moving direction of the first cutter 11.

For detailed cutting steps for this creation, please refer to Figure 4-1 to Figure 4-2. When the automatic cutting device starts to operate, the feeding device transports the material along the feeding path R to the first side cutting block 21, and the piece 30 is operated at a first time. a state, in the first state, the automatic cutting device drives the first cutter 11 to cut downward, and the first die 111a and the first blade 121a cut a first cut on the material. Side 33 (wherein the second die 111b and the second blade 121b also cut a second break side 34 at the position corresponding to the second side cutting block 22 of the material, however, the cutting device In the initial operation, the material corresponding to the material must have a piece of excess waste in the subsequent section of the tool, thereby cutting the desired rounded corners on the first cutting side 33 (ie, the first rounded corners 115a, 115b and Second fillet 116a, 116b). Then, the feeding device continuously conveys the material in the direction of the feeding path R, and moves the material to the second side cutting block 22 for cutting. At this time, the material 30 is operated in the second state. In the second state, the automatic cutting device drives the first cutter 11 to be cut downward, by the second die 111b and the second cutter. The front 121b cuts a second break side 34 on the material to cut the cost of the finished product piece 30. While the second cutting side 34 is cut, the first die 111a is simultaneously cut on the material into the first cutting side 33 of the other web 30, that is, the cutting can be cut in one cut. Corner.

In addition, in order to prevent the web 30 from being cut off when the web is cut, or because the scrap 30 cannot be separated from the scrap due to static electricity, the cutting tool 10 further includes an elastic mechanism 13 for dislocation.
