Description
【発明の詳細な説明】 〔産業上の利用分野〕 本発明は、製筒装置などとして用いられるロール成形装
置に係るものである。The present invention relates to a roll forming apparatus used as a cylinder forming apparatus or the like.
従来のロール成形装置は、第７図に示すようにロール１
と回転軸８にゴム材２を被覆したゴムロール６とを圧接
し、このロール１とゴムロール６との間に板材３を通し
てゴムロール６のゴム材２がロール１の形状に応じて圧
没することを利用して板材３をロール成形するものであ
った。A conventional roll forming apparatus is provided with a roll 1 as shown in FIG.
And a rubber roll 6 coated with the rubber material 2 on the rotating shaft 8 by pressure contact, and a plate material 3 is inserted between the roll 1 and the rubber roll 6 so that the rubber material 2 of the rubber roll 6 is sunk according to the shape of the roll 1. The plate material 3 was roll-formed by utilizing this.
従って、板材３をテーパー面を有する円錐形状にロール
成形する場合は、第８図に示すように所望する円錐形状
のロール１と同形の円錐形状のゴムロール６とを圧接し
てロール成形していた。Therefore, when the plate material 3 is roll-formed into a conical shape having a tapered surface, the desired conical roll 1 and the conical rubber roll 6 of the same shape are pressed into contact with each other as shown in FIG. .
しかしながら、このような従来のロール成形装置では円
筒形状あるいはそれに近いものからかなり急角度なテー
パー面を有する円錐形状までいろいろな形状にロール成
形する場合は、ロール１を所望の形状のものにいちいち
取り替えるだけでなくゴムロール６もこれと同形のもの
に取り替えなければならず非常に厄介であった。However, in such a conventional roll forming apparatus, when roll forming into various shapes from a cylindrical shape or a shape close thereto to a conical shape having a taper surface with a steep angle, the roll 1 is replaced with a desired shape one by one. Not only that, but also the rubber roll 6 had to be replaced with one of the same shape, which was very troublesome.
また、このようにロール１とゴムロール６双方とも適宜
取り替え方式であるから、ロール１だけでなく高価なゴ
ムロール６も多種類用意しなければならずそれだけ製品
もコスト高となっていた。Further, since both the roll 1 and the rubber roll 6 are appropriately replaced in this way, not only the roll 1 but also a large number of expensive rubber rolls 6 must be prepared, and the product becomes expensive accordingly.
一方、ロール１が円錐形状であってもゴムロール６を取
り替えずに常に円筒形状のものを使用して円錐形状にロ
ール成形すると、ロール１の各所で径が異なるためロー
ル１の径の小さい部分が大きい部分に比べその分ゴムロ
ール６に対してすべるからゴムロール６を傷める上正確
なロール成形はできなかった。On the other hand, even if the roll 1 has a conical shape, if the rubber roll 6 is not replaced and a cylindrical one is always used to roll-form a conical shape, the diameters of the rolls 1 are different from each other. Since the rubber roll 6 slides by that amount as compared with the large portion, the rubber roll 6 is damaged and accurate roll forming cannot be performed.
本発明は、このような欠点を解決したロール成形装置を
提供するものである。The present invention provides a roll forming apparatus that solves such drawbacks.
添付図面を参照して詳述すると次の通りである。 The detailed description will be made with reference to the accompanying drawings.
ロール１とこのロール１に接するゴム材２との間に板材
３を通してこの板材３をロール成形するロール成形装置
において、前記ゴム材２を平板４上に設け、この平板４
の下方にフリーベアリング５を多設して平板４をあらゆ
る方向に摺動自在としたことを特徴とするロール成形装
置に係るものである。In a roll forming apparatus for forming a plate material 3 by rolling a plate material 3 between a roll 1 and a rubber material 2 in contact with the roll 1, the rubber material 2 is provided on a flat plate 4, and the flat plate 4
The present invention relates to a roll forming apparatus characterized in that a plurality of free bearings 5 are provided below the plate so that the flat plate 4 can slide in any direction.
所望する形状のロール１を、平板４上に設けて平板状に
設けたゴム材２に当接して、このロール１とゴム材２と
の間に板材３を通して板材３がロール１によりゴム材２
に圧没することによりロール１の形状に応じて板材３が
ロール成形される。A roll 1 having a desired shape is provided on a flat plate 4 and is brought into contact with a rubber material 2 provided in a flat plate shape, and a plate material 3 is passed between the roll 1 and the rubber material 2 so that the plate material 3 is rolled by the roll 1.
The plate material 3 is roll-formed according to the shape of the roll 1 by being pressed into.
平板４はフリーベアリング５によりあらゆる方向に摺動
自在であるからロール１の廻動と共に廻動方向に摺動す
る。Since the flat plate 4 is slidable in all directions by the free bearing 5, the flat plate 4 slides in the rotational direction as the roll 1 rotates.
従って、例えばロール１が円筒形状の場合は平板４は真
っすぐ板材３と共にロール１の廻動方向に摺動し、ロー
ル１が円錐形状の場合は平板４はロール１の回転軸線と
平板４が交わる交点を中心に摺動廻動し、ロール１の廻
動と共に板材３をロール成形する。Therefore, for example, when the roll 1 has a cylindrical shape, the flat plate 4 slides along with the straight plate member 3 in the rotating direction of the roll 1, and when the roll 1 has a conical shape, the flat plate 4 intersects the rotation axis of the roll 1 and the flat plate 4. The plate material 3 is roll-formed along with the rotation of the roll 1 by sliding around the intersection.

形せしめるものである。That is, the drawing shows a case where a urethane rubber plate is attached as a rubber material 2 on a flat plate 4 made of metal, and the flat plate 4 is placed on free bearings 5 provided on a table 7. In the figure, reference numeral 21 is a notch provided on the surface of the urethane rubber plate in a grid pattern, and when the roll 1 is pressed by the notch 21, the roll 1 evenly presses the urethane rubber plate and the shape of the roll 1 is accurately determined. The plate material 3 is roll-formed into a different shape.

ル成形する場合を図示している。In this illustrated apparatus a, first, the roll 1 having a desired shape is attached to the rotary shaft 8 and the taper surface (roll surface) of the roll 1 is pressed tightly against the rubber material 2. It must be horizontal, and for that purpose, the front and rear of the holding device b are swingably provided. In the drawing, the holding device b is tilted according to the inclination of the taper surface of the roll 1 with the fulcrum shaft 9 as the fulcrum to support the taper surface in a horizontal state, and the table 7 is pushed up by the cylinder 10 to support the roll 1. 1 and the rubber material 2 are pressed into close contact with each other, and a plate material 3 is inserted between the roll 1 and the rubber material 2 to perform roll molding.

々独自にフリー回転する円筒形状の分割ゴムロール22
（図面は７分割したものを図示している）を圧接し、こ
のロール１と分割ゴムロール22との間に板材３を通して
円錐形状にロール成形するものである。Incidentally, FIG. 6 shows an embodiment of another invention which achieves the same purpose as the present invention. A cylindrical split rubber roll 22 in which each part of the conical roll 1 is independently rotatable independently.
(The drawing shows a product divided into seven parts), and the plate material 3 is inserted between the roll 1 and the divided rubber roll 22 to form a conical shape.
即ち、ロール１の形状がテーパー面を有し各部で径の違
う円錐形状であっても、分割ゴムロール22の各部は夫々
独自にフリー回転するのでロール１の基端側の径の大き

り換えずに、すべりも生じることなく正確なロール成形
ができるものである。That is, even if the shape of the roll 1 is a conical shape having a tapered surface and different diameters at each part, each part of the split rubber roll 22 is independently rotated independently, so that it is in contact with the part having a large diameter on the base end side of the roll 1. Since the portion is fast and the portion in contact with the tip side portion of the roll 1 having a small diameter rotates slowly, accurate roll forming without changing the split rubber roll 22 with respect to the roll 1 having various shapes and without causing slippage. Is something that can be done.
本発明は、上述のように構成したからゴム材の方は全く
取り替えることなく単にロールを所望の形状に取り替え

ロール成形でき、ゴムロールも取り替え用の多数のゴム
ロールも必要のないロール成形装置となる。Since the present invention is configured as described above, the rubber material can be roll-formed into a conical shape having various tapered surfaces by simply replacing the roll with a desired shape without replacing the rubber material, and a large number of rubber rolls can also be replaced. The rubber forming device does not require a rubber forming device.
また、ゴム材を設けた平板の下方にフリーベアリングを
多設して平板をあらゆる方向に摺動自在としたから、ロ
ールの形状が円錐形状であってもゴム材に対してすべる
ことがなくゴム材を傷めず正確にロール成形できるロー
ル成形装置となる。In addition, since multiple free bearings are installed below the flat plate on which the rubber material is provided so that the flat plate can slide in all directions, even if the roll shape is conical, it does not slip on the rubber material. The roll forming device can accurately roll-form without damaging the material.
