本発明はチップ製作機械用の刃およびその製造方法に関
する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a blade for a chip making machine and a method of manufacturing the same.
チップ製作機械における切削刃の研摩、調節および交換
のための高い費用を回避するために、摩耗の際に新しい
ものに交換される鋼帯刃は公知である。In order to avoid high costs for sharpening, adjusting and replacing cutting blades in chip-making machines, steel strip blades are known which are replaced with new ones when they wear out.
しかしながらこのような刃は、木材繊維の長さ方向に細
分されたチップを作ることができないという欠点がある
ので、特定範囲の繊維長のチップを作るためには、付加
部品としで切れ目入れ刃を使用せねばならず、チップ製
作の際費用を増大させることになる。However, such a blade has the disadvantage that it cannot make chips that are subdivided in the length direction of the wood fibers, so in order to make chips with a specific range of fiber lengths, a scoring blade is required as an additional component. This increases the cost of chip fabrication.
本発明の課題は、簡単かつ費用を節約して所望の繊維長
のチップの製作を可能にする刃を提供することにある。The object of the invention is to provide a blade that allows the production of chips of the desired fiber length in a simple and cost-effective manner.
この刃は簡単に作られており、申し分のない動作で比較
的長い寿命をもつようにする。This blade is simply made, allowing it to have a relatively long life with impeccable operation.
本発明の別の課題は、このような刃の簡単かつ費用を要
しない製造法に関するものである。Another object of the invention is a simple and inexpensive manufacturing method for such a blade.
これらの課題を解決するために本発明によれば、刃が全
長にわたって所定の間隔で複数の中断部ををもつ刃先を
有する一体の鋼帯からなり、これらの中断部がチップを
横分離する切れ目入れ部として構成されている。To solve these problems, according to the invention, the blade consists of a one-piece steel strip having a cutting edge with a plurality of interruptions at predetermined intervals over its entire length, these interruptions forming cuts that laterally separate the chips. It is configured as a container.
さらに本発明によそば、切れ目入れ部が、刃先縁に対し
て直角に刃先へ打抜かれたスリットとそれに隣接して刃
先から曲げ出された横刃先とにより形成されるか、刃先
から突出するＵ字状あるいはＶ字状突起により形成され
ている。Further, according to the present invention, the scoring portion is formed by a slit punched into the cutting edge at right angles to the cutting edge and a horizontal cutting edge bent from the cutting edge adjacent to the slit, or by a U protruding from the cutting edge. It is formed by a letter-shaped or V-shaped projection.
このような刃を製造する゛ため本発明によれば、無端に
製造されて研摩された鋼帯を、個々の刃に分離する前に
、刃先縁の範囲に互いによみ合う１対の歯車からなる打
抜ロールに通し、チップ長に対して望まれる間隔で直線
状刃先縁の中断部をまだ無端の鋼帯へ打抜く。In order to produce such a blade, according to the invention, the endlessly produced and ground steel strip is, before being separated into individual blades, made up of a pair of gear wheels that read into each other in the area of the cutting edge. Pass through a punch roll and punch out the interruptions of the straight cutting edge at the desired spacing relative to the chip length into a still endless steel strip.
本発明による刃は、使い捨て刃として市販の銅帯から簡
単かつ安価に製造され、同時にこれまで必要であったチ
ップ横分離用の切れ目入れ刃を不用にする。The blade according to the invention is manufactured simply and inexpensively from commercially available copper strip as a disposable blade, and at the same time eliminates the hitherto necessary scoring blade for lateral chip separation.
このような別体の切れ目入れ刃がなくなることは、刃の
製造を簡単にするのみならず、この切れ目入れ刃の時間
を要する挿入および位置調節をも不要にする。The elimination of such a separate scoring blade not only simplifies the manufacture of the blade, but also eliminates the need for time-consuming insertion and positioning of the scoring blade.
刃の挿入、交換および調節に要する時間が短いことは、
チップ製作機械の停止時間が少なくてすむことをも意味
する。The short time it takes to insert, change and adjust the blade means
This also means less downtime for the chip production machine.
本発明の別あ利点は、無端の帯からこれを研摩して切れ
目入れ部を形成した後に所望の長さに分離して刃が構成
されるので、刃の多量生産が可能になる。Another advantage of the present invention is that the blades are constructed by grinding the endless strip to form the scoring portions and then separating the blades into desired lengths, thereby making it possible to mass produce the blades.
以下図面により本発明の実施例について説明する。Embodiments of the present invention will be described below with reference to the drawings.

It has a plurality of interruptions which form incisions 13.14.15.
これらの切れ目入れ部１３．１４，１５によって、刃長
の長さで生ずるチップが切れ目入れ部の相互間隔に相当
する短いチップに分けられる。By means of these scorings 13, 14, 15, the chips resulting from the length of the blade are divided into short chips corresponding to the mutual spacing of the scorings.
