Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a cutting knife. This cutting knife is a knife used to cut workpieces such as leather, fabric, paper, paper cartons, veneer, rubber, resin plates, thin metal plates, etc. into the desired shape, and can be easily processed by press work. It is possible to process objects into desired shapes.

Since a workpiece can be easily formed into a desired shape by pressing, this processing method is used in many industrial fields.

In the addition method I-1, as shown in FIG. 1, the workpiece 3 is usually placed on soil on which a bedding 2 such as a rubber plate or a synthetic resin plate is placed on a processing table 1, and then, The workpiece is cut into a desired shape by lowering a cutter blade 4 attached to a press machine (not shown) from above.

Due to this processing method, the underlay placed under the workpiece is extremely worn out, and as a result, it is necessary to replace it frequently.

In view of this situation, the present invention aims to provide a cutting tool that can cut a workpiece into a desired shape without using a cutting board.

Hereinafter, the cutting die cutter of the present invention will be explained in detail with reference to the attached 11 drawings.

FIG. 2 is a perspective view showing an embodiment of the cutting cutter 5 of the present invention, in which the cutting edge has a zigzag shape with a pointed portion 51, and a blade 52 is provided on the zigzag edge. It is something.

The pointed end of the cutting edge may be serrated as shown in Fig. 3, or may have a two-step taper as shown in Fig. 4. Any shape may be used, and the shape and the number of pointed portions are determined by appropriately selecting 17 depending on the location of use, conditions of use, etc.

The blade provided on the zigzag-shaped cutting edge of the blade is either single-edged as shown in FIG. 5, which has been commonly used in the past, or double-edged as shown in FIG. 6.

Depending on the conditions of use, the blade or double sword may be formed into a two-stage H shape, and the tips of these blades may be formed at an acute angle or an obtuse angle, which is determined by the conditions of use.

As mentioned in Ar1, the shape of the cutting edge of the cutting die cutter of the present invention is a zigzag shape with a pointed portion, and since the zigzag shaped cutting edge is provided with a blade, there is a difference between the machining machine and the workpiece. With the workpiece set in a state with a space between the two, place the cutting tool of the present invention into a press machine.
If it is lowered from both sides, the tip of the cutting tool can easily cut into the workpiece.

Since the contact area between the tip and the workpiece is small and the pressure exerted is extremely high, the tip can cut into the workpiece very easily.

After the pointed part cuts into the workpiece, the zigzag-shaped taper part cuts the workpiece while sliding diagonally to the workpiece, and the zigzag-shaped part of the cutting blade is located below the workpiece. Sometimes, the workpiece is machined into the desired shape and the work is completed, so the cutting tool is returned to the upper position and the same work is repeated again. As can be seen from this, the gap between the workpiece and the processing table needs to be at least larger than the height H of the zigzag shape of the punching tool (see FIG. 1).

Next, an example in which the cutting cutter of the present invention is used in food packaging work will be explained.

A large number of plastic containers 71 having flanges are placed in the groove 61 of the tray 6 placed on the processing table 1, and jelly or ice cream is injected into the plastic containers 7. Ru. After that, a sheet material 8 such as aluminum foil is placed on the bottom of the whiteboard container 7, and the sheet material and the plastic container's plastic container are adhered by heat/ru, etc., and the plastic container is filled with jelly, etc. Foods such as frozen desserts are vacuum-backed.

Here, since the plurality of silastic containers 7 integrated via the note material 8 are separated one by one, the cutting tool 5 of the present invention is used, which makes the work much more efficient.

11. As shown in FIG. 8, a plurality of plastic deck containers 7 integrated via 7-1-1 are placed in a press machine (not shown) in the exact size shown in FIG. ) of the cutting die cutter 5 of the present invention (to quickly change the shape corresponding to the shape of the plastic deck container), by lowering the cutting die cutter 5, it is very easy to cut out the glass. It is possible to separate the container 7.

In this food packaging work, when the conventional cutting knife 4 is used, the sheet material 8 and the plurality of plastic containers 7 shown in FIG. Inversion of the plurality of plastic containers 7 integrated into the sheet material 8 because they had to be placed upside down on the underlay under the attached press machine and separated with the cutter cutter 4 after setting the position. Although a process was necessary,
By using the cutting die cutter 5 of the present invention, reversing work can be omitted and the work can be extremely efficient.

Moreover, since there is no need for drying pads, there is a great effect that the cost of underlays, which are consumable items, and the time required to replace the underlays are unnecessary. In the following explanation, the cutting tool was moved from the tip (7), but the same effect can be obtained by any movement, such as from left to right or upward from the tip. It is a work place space.
This also has the advantage of making it possible to utilize resources effectively.

The cutting cutter of the present invention can be used for the above-mentioned food packaging work, evening (evening), when the workpiece is thin, such as when packing medical goods and goods into bags.
, is applicable to soft objects. , -Also, thick extraction force [1] When the workpiece is made of synthetic resin, it is possible to conduct the heater to the cutting tool and move the cutting tool with the heated cutting tool by two J degrees, 17 In addition, by making a cutting die cutter like the one of the present invention, the heating property due to heat is also improved, so it is a cutting die cutter that can be used in a wide range of industries, and it is believed that the effects it provides are great. I can say it.
