SOLUTION: A projection 3 for displaying required characters, symbols and the like is integrally formed on the upper surface of a synthetic resin or metal substrate 1, and the lower end is inserted through a plywood 4 constituting a punching die on the lower surface of the substrate. Provided a supporting leg 6 reaching the lower surface of the plywood.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a dial plate for engraving characters, symbols, and figures on a corrugated cardboard or the like by fixing it in advance on a punching die for punching cardboard or corrugated paper. It is about.

[0002]

2. Description of the Related Art For example, when a corrugated paperboard is punched into a predetermined shape by a punching die for box making, a part of a punching die is formed so that a part number, a product name and the like are simultaneously imprinted on the corrugated paperboard. As the dial to be fixed in advance, the one shown in FIG. 6 is conventionally known. That is, when characters, symbols, and the like are linearly displayed on the upper surface of a rectangular substrate 1 made of a synthetic resin, the projections 3 are integrally formed, and the through holes 2 are formed in a part of the substrate 1. The dial shown in FIG. 7 has a large number of conical projections 3 integrally formed on the upper surface of a die-cast substrate 1 made of aluminum or the like to display characters, symbols, and the like. These dials were used by being fixed to a plywood 4 constituting a punching die with nails 5 as shown in FIG.

[0003]

However, if the height H of the dial used in this manner is not always kept at a certain level of accuracy, the pressing force on the corrugated cardboard becomes unstable and the printing may become unclear. However, since the thickness of the plywood 4 was largely different depending on the object, there was a possibility that the height H would not be constant. For this reason, conventionally, a thin plate-like inclusion has been inserted between the upper surface of the plywood 4 and the substrate 1 to adjust the height. For this reason, there was a drawback that the installation took a lot of time and effort. Also, the height H fluctuates due to distortion of the plywood 4 itself during use, so that it was difficult to perform stable printing.

The present invention has been made to solve the above-mentioned problems, and an object of the present invention is to provide a corrugated cardboard engraving dial which can be easily attached to a plywood and can always perform stable printing.

[0005]

For this purpose, the present invention provides a corrugated cardboard engraving dial plate in which projections for displaying required characters and symbols are integrally formed on an upper surface of a synthetic resin or metal substrate. It is characterized in that a support leg is provided on the lower surface of the substrate, which is inserted into a plywood forming a punching die, and a lower end of the plywood reaches the lower surface of the plywood. Further, the present invention is characterized in that, in the dial plate for engraving corrugated paper, the supporting legs are integrally formed on the lower surface of the substrate. Further, the present invention is characterized in that, in the dial plate for engraving corrugated cardboard, a supporting leg is screwed to a lower surface of the substrate.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, an embodiment of the present invention will be described with reference to FIGS. The lettering board for engraving corrugated cardboard shown in FIG. 1 is made of synthetic resin and has a linear projection 3 for displaying characters, symbols, etc. integrally formed on the upper surface of a substrate 1.
A column-shaped support leg 6 is integrally formed on the lower surface of. As shown in FIG. 2, as shown in FIG. 2, a mounting hole 7 is formed in the plywood 4 constituting a corrugated paper punching die in a penetrating manner, and the lower end of the supporting leg 6 is inserted through the mounting hole 7. It reaches the lower surface of the plywood 4 so that its height H is constant. The nail 5 is used to rotate and prevent the board 1 from being pulled out. However, if the support leg 6 can be inserted through the mounting hole 7 tightly, the nail 5 is not always necessary.

The dial according to the present invention shown in FIG. 3 is made of aluminum die-cast, and has a large number of conical protrusions 3 integrally formed on the upper surface of a substrate 1 to provide required characters, symbols, etc. And two columnar supports 6 are integrally formed on the lower surface.
It was formed this time. As shown in FIG. 4, the dial is attached to the plywood 4 by opening two attachment holes 7 through which the support legs 6 can be inserted. In this case, since the substrate 1 is not likely to rotate, the mounting is further facilitated.

The corrugated paper punching die having the dial attached thereto is set on a die mounting surface of a punching machine (not shown) and is used for punching corrugated paper for box making. By making the lower end of 6 abut on the mold mounting surface, the height H can be made constant regardless of the thickness of the plywood 4. Therefore, the accuracy of the height H can be kept high without affecting the thickness of the plywood 4, and the pressing force of the projections 3 on the corrugated paper can be kept constant, so that stable and clear printing can always be performed. It should be noted that a thin plate-like inclusion is stuck to the lower end surface of the support leg 6 and interposed between the lower end surface and the mold mounting surface, so that the rolling force can be more finely adjusted.

On the other hand, the dial according to the present invention shown in FIG. 5 is formed by integrally forming a screw shaft 8 on the lower surface of the substrate 1 and screwing a supporting leg 9 to the screw shaft 8. In this case, if several types of supporting legs 9 having different lengths are prepared in advance, it can be easily coped with by replacing the supporting legs 9 according to the thickness of the plywood 4 to be used. The height H can be finely adjusted by appropriately loosening the screwing of the support legs 9.
For this reason, a minute error in the thickness of the plywood 4 can be dealt with.

[0010]

As described above, the dial plate for engraving corrugated cardboard according to the present invention can be easily mounted by providing the supporting legs on the lower surface of the substrate and penetrating the plywood, and can improve the height accuracy and achieve stable printing. It has a beneficial effect.
