Embodiment 1

[0037] Fig. 1 (a) is the top view of an embodiment of the blanking die of the present invention, the blanking of the cutting blade 1 with a height of 23.6mm is placed in the narrow groove of the square base material 2 (plywood plywood with a thickness of 18mm) In the mold 8, the side faces of the four sides of the base material 2 are reinforced by four L-shaped angle irons 5 . The L-shaped angle irons 5 are fixed in a state connected at right angles using corner members 6 having right-angled side surfaces at the corners. Screws 7 are used to fix the L-shaped angle iron 5 to the base material 2 and the corner member 6 . Fig. 1(b) is a cross-sectional view along line X and X in Fig. 1(a). L word angle iron also can use in reverse as Fig. 1 (c).

[0038]The shape seen from the outside and the inside of the corner member 6 is shown in a perspective view in FIG. 2( a ) and FIG. 2( b ). Figure 3(a) ~ Figure 3(c) It is a perspective view illustrating the exploded structure of the...

Embodiment 2

[0041] FIG. 4( a ) is a plan view of another embodiment of a component that changes the corner component 6 into the shape shown in the perspective view of FIG. 4( b ). and Figure 1(a) ~ Figure 1(c) The same symbols mean the same components. The base material 2 of the blanking die shown in Fig. 4(a) is also cut into the shape of an angle iron 5 and a corner part 6 as shown in Fig. 3(a), and each part is placed on it and fixed by a screw. 7 fixed.

Embodiment 3

[0043] In Fig. 5 (a) it is shown that the F-shaped bar 5' (made of steel) is used to replace Figure 1(a) ~ Figure 1(c) Partial cut-away perspective view of the L-shaped angle iron 5 in . Like the L-shaped angle iron 5, the F-shaped bar 5' can also be used up and down.

[0044] In addition, Fig. 5(b) shows a partial cross-sectional perspective view when using the 匚-shaped angle iron 5". For the 匚-shaped angle iron 5", it can also be used up and down in reverse with that of Fig. 5(b), and the parenthesis can also be used The upper and lower sides and sides of the material 2 are used for reinforcement.

Abstract

This invention provides with a cutter die which can produce products with high accuracy and without warps, even though it's a large blank. A blank 2 which is formed with thin slots for inserts into a cutting blade 1 and which presents a triangular shape in the upside view direction, and a cutter die 8 for opposite setting the cutting edges of the cutting blades into the thin slots, the cutter die characterizes in that: reinforcement members 5, 6, reinforce at least the two sides of the side faces of the blank 2, in order to maintain the horizontal level of the cutting edge of the cutting blade 1.

Description

technical field [0001] The present invention relates to a punching die for punching a sheet-like material such as a plastic board or a corrugated cardboard into a desired shape. In particular, it relates to a punching die with high punching accuracy that prevents deflection of the base material during operations such as transportation and demolding in a large punching die, and does not damage the horizontality of the blade portion. Background technique [0002] A conventional punching die will be described based on the drawings. [0003] Figure 7 It is a perspective view of a conventional punching die. [0004] In the past, as a punching die for punching a sheet-like material such as a plastic plate or a corrugated cardboard into a desired shape, for example, a plate-shaped body (referred to as "" The base material 2 composed of the base material ") is provided with a through thin groove 4, and the cutting blade (pointed blade) 1 is put into the thin groove 4 and fixed by...
