Abstract

PURPOSE:To prevent die-stamped images from becoming unclear near both ends, by making uniform the pressing-in quantity and the pressing-in force of die- stamping parts against a surface to be die-stamped at each part. CONSTITUTION:Die-containing holes 7, 7 opened to the tip side of a main body 3 are provided in parallel with each other at the tip part of the main body 3, and dies 4, 4 are individually slidably contained in the holes 7, 7. A sealed chamber 9 containing an oil 8 as a fluid is provided at an intermediate part of the main body 3. Through-holes penetrating from bottom parts of the holes 7, 7 to the chamber 9 are provided, and sliding pins 5, 5 are inserted through the through- holes with the outer peripheries thereof maintained to be airtight. In this case, when a die-stamping force is externally exerted on the main body 3 in the condition wherein the die-stamping parts 11, 11 are brought into contact with the surface 2 to be die-stamped, the die-stamping force is imparted to the dies 4 through the oil 8 and the pins 5.

Description

【発明の詳細な説明】 木発ＩＪ４は刻印装置、特に曲面部分に４ｉ故の文字、

なガスボンベ・の曲面部分への刻印等に利用できる。[Detailed description of the invention] Kiba IJ4 has a marking device, especially the characters of 4i on the curved part,
It can be attached to a device for marking marks, etc., and can be used, for example, to mark the curved surface of a gas cylinder as shown in Fig. 1.

従来、一定の複数の文字、マーク等を刻印する場合には
、その文字等を凹又は凸に刻設した刻印工具（第２図）
を特別に製作し、この刻印工具を刻印場所に打ちつけて
所望の刻印加工を施している。Conventionally, when stamping a certain number of characters, marks, etc., a stamping tool is used that engraves the characters, etc. in a concave or convex manner (Fig. 2).
is specially manufactured, and the desired engraving process is performed by hitting this engraving tool on the engraving location.

。However, if there are a large number of characters, etc. in the direction of the curve of the curved surface, it is difficult to print each character in the center part and both ends. 1
(an, a++ o stamped jiff (21heno E
jE lower r + 1 changes greatly. That is, the pressure F(, i+) is large at the center Tθ, and on the other hand, the reduction amount is small at both ends, making it impossible to make a vinegar mark over the entire area.

くなるのである。In other words, even if an impact force or d load is applied in one direction to the main body (1) of the marking, the amount of movement of the printing part in the direction parallel to the direction of these forces is constant over the entire area, but the amount of movement on the marking surface is The depth of penetration of the printed portion is not constant, being deeper at the center and shallower at both ends.

が浅くなるからである。In the center, the printing part (11) advances to one corner of the marking surface (2), but as it goes to both ends, the printing part (
11) advances obliquely to the surface to be marked (2), and the amount of bite in the direction perpendicular to the surface to be marked (2) becomes shallow.

本発明は、両端に行くに従って刻印が不鮮明になること

の課題とする。An object of the present invention is to make the amount of biting and biting force of the printing part on the stamped surface constant at each part in order to prevent the marking from becoming unclear toward both ends.

動できるようにし、該刻印せたことである。The technical means of the present invention for solving the above problems is to form a closed chamber containing an incompressible fluid in the main body, and arrange a marking tool on the tip side of the closed chamber so that each marking tool can be independent. It was made to be able to slide, and it was engraved.

（Ｉｆｉ被刻印１川の曲面に倣って当接する。These technical means are in constant contact with each other through the following actions. Therefore, when the direction to be marked is a curved surface, the tool located in the center of the stamping tool group is recessed, and the marking tools located at both ends are connected via the fluid joining element, so one of the tools is pushed in. Therefore, the printing in the tip of each marking tool
(Ifi to be engraved 1. Contact following the curved surface of the river.

から、各刻印工具には同等の刻印力がイｑ加される。In this state, if an impact force or partner is applied to the main body, this force is directly or firmly transmitted to the marking tool via the fluid in the closed chamber, and since this fluid is compressible by 1", , an equal marking force is applied to each marking tool.

i, differential rJf is available, and if you look at the micro al, it is medium heat bar 19
The marking tool is slightly recessed into the main body (7) and a certain marking force is generated, while at both ends, it is slightly protruding from the main body and a constant marking pressure is applied. is also possible.

本発明の技術手段の」二記作用から、本発明は次の特有
の効果をイ１する。From the two effects of the technical means of the present invention, the present invention has the following unique effects.

複数の刻印工具には刻印加」二時に一定の刻印力が作用
することとなるから、すなわち、被刻印面に対する印字
部の喰い込み量か一定となる捷で、各刻印工具が被刻印
面に圧下されるから、いずれの部分での刻印も鮮明に々
る。Since a constant marking force is applied to multiple marking tools during marking, in other words, each marking tool is applied to the marking surface with a constant amount of penetration of the printing part into the marking surface. Since it is pressed down, the engravings on any part are clearly visible.

また、各刻印工具は一方が没入すると他方が進出すると
いうように曲面の態様に倣って各印字部が配列されるか

る。Furthermore, since each marking tool is arranged in such a manner that one marking tool goes in and the other moves out, the printing parts are arranged to follow the shape of the curved surface, so it can accurately correspond to curved surfaces where the curvature is not constant.
