Abstract

PROBLEM TO BE SOLVED: To provide injury prevention by decreasing paper powder during punching of a corrugated cardboard case, in blade material machining of a soft rotary die punching blade.SOLUTION: From the front end of the soft rotary die punching blade for the corrugated cardboard case to the middle thereof, wavy machining is carried out on the front and rear surfaces thereof. Thereby, the cut surface after punching the corrugated cardboard case becomes wavy, thus becoming less susceptible to hand injury and also decreasing the paper powder.

Description

本発明は、段ボールケース用ソフトロータリーダイ打抜刃に関し、刃材の波形状に関するものです。  The present invention relates to a soft rotary die punching blade for a corrugated cardboard case, and relates to a corrugated blade material.

従来の段ボールケース用ソフトロータリーダイ打抜刃として用いた細かい波形状の刃材に加工をすると刃先のＶ溝にヒビやクラックが入り刃材先端部やノッチ部分の破損が多い。  When processing into a fine corrugated blade material used as a conventional soft rotary die punching blade for corrugated cardboard cases, cracks and cracks are found in the V-groove of the blade edge, and the blade material tip and notch portions are often damaged.

また、ノッチ部分と刃先部分が均等に並んでいない為、刃材を加工するとヒビやクラックが入りやすくアンビルに食い込むので、加工を施した刃材は破損してしまう。  In addition, since the notch portion and the blade edge portion are not evenly arranged, if the blade material is processed, cracks and cracks are likely to occur, and the processed blade material is damaged because it bites into the anvil.

以上に述べた加工では、段ボールケース用ソフトロータリーダイ打抜刃の刃材加工は、刃材が厚く刃先がＶカットで波形状に曲げるとＶ溝にヒビやクラックが入り加工困難であった。  In the processing described above, the processing of the blade material of the soft rotary die punching blade for the cardboard case is difficult if the blade material is thick and the cutting edge is bent into a wave shape with a V-cut, causing cracks and cracks in the V-groove.

本発明は、このような加工が有していた問題を解決しようとするものであり、ヒビやクラックの入り難い加工を目的とするものである。  The present invention is intended to solve the problems that such processing has, and is intended for processing that does not easily cause cracks or cracks.

そして、本発明は上記目的を達成するために刃の先端部から中央にかけて表裏面に波形状の加工を設けたものである。  In order to achieve the above object, the present invention is provided with corrugated processing on the front and back surfaces from the tip of the blade to the center.

本発明のソフトロータリーダイ打抜刃の刃材加工は、段ボールケース打抜時の紙紛を軽減しけが防止を提供できる。  The blade material processing of the soft rotary die punching blade of the present invention can reduce paper dust at the time of punching the cardboard case and provide injury prevention.
