Description

本発明は主に金属製の板材、棒材を円弧状に曲げることのできるワーク曲げ装置に関するものである。   The present invention relates to a workpiece bending apparatus that can bend a metal plate or bar in an arc shape.

従来、金属製の帯状やテープ状の板材を所望角度に曲げる板材曲げ装置としては特許文献１、２に示すようなものがあった。これは帯状或いはテープ状の板材が挿通されるスリット孔が形成されている軸体と、その軸体の外周部に配置されたスリーブとを備え、前記スリット孔に板材を挿通させてからスリーブを所定角度回転させると板材のうちスリットの外側に突出した部分（突出部分）が、スリットの端部を曲げ支点にして曲げ加工されるものや、特許文献３〜５に示すように板材を挟持片によって両側から挟持する挟持機構と挟持した板材に押しつけて板材を曲げ加工する押し機構を備えたもの等がある。   Conventionally, as a plate material bending apparatus that bends a metal belt-like or tape-like plate material to a desired angle, there are those shown in Patent Documents 1 and 2. This comprises a shaft body in which a slit hole is formed through which a belt-like or tape-like plate material is inserted, and a sleeve disposed on the outer periphery of the shaft body, and the sleeve is inserted after the plate material is inserted into the slit hole. When the plate material is rotated by a predetermined angle, a portion of the plate material that protrudes to the outside of the slit (projection portion) is bent using the end portion of the slit as a bending fulcrum, or as shown in Patent Documents 3-5 There is a mechanism equipped with a clamping mechanism for clamping from both sides and a pressing mechanism for bending the sheet material by pressing against the sandwiched sheet material.

前記特許文献１、２記載の板材曲げ装置には次のような課題がある。
（１）軸体のスリット孔の幅が固定であるため、一つの軸体では厚さの異なる板材を曲げ加工することができず、厚さの異なる板材ごとに異なる軸体を用意しなければならず、在庫管理が面倒であり、コスト高になる。
（２）軸体のスリット孔の長さも限られているため、スリット孔の長さより幅広の板材を曲げ加工することはできず、加工可能な板材の幅が限定されてしまう。 The plate bending apparatus described in Patent Documents 1 and 2 has the following problems.
(1) Since the width of the slit hole of the shaft body is fixed, it is not possible to bend a plate material having a different thickness with one shaft body, and a different shaft body must be prepared for each plate material having a different thickness. In addition, inventory management is cumbersome and costly.
(2) Since the length of the slit hole of the shaft body is also limited, a plate material wider than the length of the slit hole cannot be bent, and the width of the plate material that can be processed is limited.

前記特許文献３〜５記載の板材曲げ装置には次のような課題がある。
（１）板材を挟持する挟持機構や、挟持した板材に押しつけて板材を曲げ加工する押し機構を個別に設けなければならず装置が大掛かりとなる。
（２）厚さの異なる板材の曲げ加工をしたり、板材の曲げ角度の変更をしたりする場合、挟持機構や押し機構の部品の交換や調節等をしなければならず手間がかかり、その分だけコスト高になる。 The plate bending apparatus described in Patent Documents 3 to 5 has the following problems.
(1) A clamping mechanism for clamping the plate material and a pressing mechanism for bending the plate material by pressing against the clamped plate material must be provided separately, which makes the apparatus large.
(2) When bending plate materials with different thicknesses or changing the bending angle of plate materials, it is necessary to replace or adjust the parts of the clamping mechanism or push mechanism, which is troublesome. The cost will increase by the amount.

本発明は簡易な構成で、形状、厚さ、幅等の異なるワークを所望角度に曲げ加工可能なワーク曲げ装置を提供するものである。   The present invention provides a workpiece bending apparatus capable of bending workpieces having different shapes, thicknesses, widths, and the like to desired angles with a simple configuration.

本発明のワーク曲げ装置は、曲げ加工するワークをセット可能なセット空間を備えたセット具の外側に押し具が周回可能に配置され、押し具はワークをセット具の外周面に押しつけながら回転してワークを曲げ加工可能としたものである。前記セット具は二本のセット軸を空間をあけて並べて立設してその空間をセット空間としたり、溝のある一本のセット軸を立設してその溝をセット空間としたりすることができる。それらセット軸には間隔保持具をセットしてセット軸に押し曲げ力が加わってもセット空間の間隔が広がらないようにすることができる。一方又は双方のセット軸にそれよりも外径の大きなパイプ状或いはリング状の補正具を被せて、両セット軸間の間隔を調整したり、セット具の外形を変えたり、間隔と外形の双方を変えたりすることもできる。   In the workpiece bending apparatus of the present invention, a pressing tool is disposed on the outside of a setting tool having a set space in which a work to be bent can be set, and the pressing tool rotates while pressing the work against the outer peripheral surface of the setting tool. The workpiece can be bent. The set tool may have two set shafts arranged side by side with a space between them and set the space as a set space, or one set shaft with a groove may be set up to make the groove a set space. it can. An interval holder can be set on these set shafts so that the space between the set spaces does not widen even if a pushing and bending force is applied to the set shafts. Cover one or both set shafts with a pipe or ring-shaped correction tool with a larger outer diameter to adjust the distance between the two set axes, change the outer shape of the set tool, or both the distance and the outer shape. Can also be changed.

本件出願の請求項１、２記載のワーク曲げ装置は次のような効果がある。
（１）セット具のセット空間内に、例えば板材（ワーク）を、その一部がセット空間から突出するようにセットしてから、押し具をセット具の外周を周回させることにより、押し具がワーク突出部をセット具の外周面に押し付けながら周回して、ワーク突出部をセット具の外周面に沿って曲げ加工することができ、手軽に、確実に曲げ加工ができる。
（２）押し具の周回角度を変えるだけで板材を所望の曲げ半径に曲げることができる。
（３）セット具の外周面を円弧状にすれば、ワークをその外周面に押しつけて曲げてもワーク表面に傷が付きにくい。
（４）二本のセット軸を、空間をあけて並べて立設するか、空間のある一本のセット軸を立設することによりセット具を構成できるので、ワーク曲げ装置の構成が簡潔になる。
（５）セット軸の高さを変えるだけでセット空間の深さを調節できるので、曲げ加工するワークの幅（縦向きにしたときの高さ）に合せてセット空間を変えることができ、幅の狭いワークから広いワークまで曲げ加工可能である。 The workpiece bending apparatus according to claims 1 and 2 of the present application has the following effects.
(1) For example, a plate material (work) is set in the set space of the set tool so that a part of the plate material protrudes from the set space, and then the push tool is rotated around the outer periphery of the set tool, The workpiece protruding portion can be bent while being pressed against the outer peripheral surface of the setting tool, and the workpiece protruding portion can be bent along the outer peripheral surface of the setting tool, and can be easily and reliably bent.
(2) The plate material can be bent to a desired bending radius only by changing the turning angle of the pressing tool.

(4) Since the set tool can be configured by standing two set shafts side by side with a space therebetween or by standing one set shaft with a space, the configuration of the workpiece bending device is simplified. .
(5) Since the depth of the set space can be adjusted simply by changing the height of the set shaft, the set space can be changed according to the width of the workpiece to be bent (the height when it is oriented vertically). Bending from narrow workpieces to wide workpieces is possible.

本件出願の請求項３記載のワーク曲げ装置には、上記効果の他に次のような効果がある。
（１）二本のセット軸に保持具を取り付ければ、両セット軸の開きを防止できるため、曲げ加工時にセット軸に大きな力が加わってもセット軸が傾いて空間が広がることが無く、常に同じ条件で曲げ加工可能となる。 The workpiece bending apparatus according to claim 3 of the present application has the following effects in addition to the above effects.
(1) If the holders are attached to the two set shafts, both set shafts can be prevented from opening. Therefore, even if a large force is applied to the set shaft during bending, the set shaft does not tilt and the space does not expand. Bending can be performed under the same conditions.

本件出願の請求項４記載のワーク曲げ装置には、上記効果の他に次のような効果がある。
（１）一方又は双方のセット軸にそれよりも外径の大きなパイプ状或いはリング状の補正具を被せてセット空間の幅を調整することができるため、薄いワーク、立体状のワーク等のいずれをも差し込んで曲げ加工することができる。
（２）セット軸に補正具を被せてセット軸の外径を変えることによりワークの曲げ角度をセット軸の外径に合わせて変えることができる。
（３）補正具の外形を円形のもの、角形のものに変えることにより、ワークの曲がり形状（円弧状の曲げ、角方の曲げ）や曲げ角度を変えることができる。 The workpiece bending apparatus according to claim 4 of the present application has the following effects in addition to the above effects.
(1) Since the width of the set space can be adjusted by placing one or both of the set shafts with a pipe-shaped or ring-shaped correction tool having a larger outer diameter than that, any of thin workpieces, three-dimensional workpieces, etc. Can be inserted and bent.
(2) The work bending angle can be changed in accordance with the outer diameter of the set shaft by covering the set shaft with a correction tool and changing the outer diameter of the set shaft.
(3) By changing the outer shape of the correction tool to a circular shape or a square shape, the bending shape (arc-shaped bending, bending in a square shape) or bending angle of the workpiece can be changed.

（実施形態１）
本発明のワーク曲げ装置の実施形態の一例を図１〜図４に基づいて説明する。このワーク曲げ装置は板材１を曲げ加工する場合の例である。図１、図２に示すように肉厚円盤状の内側回転体２の外周に円盤状の外側回転体５が内側回転体２と同心円状に配置されており、外側回転体５は内側回転体２の外周を図１の矢印Ａ−Ａ方向に回転（周回）可能としてある。内側回転体２と外側回転体５は相対的に回転可能であればよいため、内側回転体２を固定して外側回転体５が回転するようにしても内側回転体２を固定して外側回転体５が回転するようにしてもよい。場合によっては両回転体が異なる回転速度で回転するようにしてもよい。外側回転体５の上面には丸棒状、丸パイプ状の押し具６が立設されている。外側回転体５はモータ等の動力で回転させることも手動で回転させることもできる。手動回転の場合は外側回転体５に外側に突出するハンドルを設け、そのハンドルを操作して回転させることができる。 (Embodiment 1)
An example of an embodiment of a workpiece bending apparatus of the present invention will be described with reference to FIGS. This workpiece bending apparatus is an example in the case of bending a plate material 1. As shown in FIGS. 1 and 2, a disk-shaped outer rotating body 5 is arranged concentrically with the inner rotating body 2 on the outer periphery of the thick disk-shaped inner rotating body 2, and the outer rotating body 5 is an inner rotating body. 2 can be rotated (turned) in the direction of arrow AA in FIG. Since the inner rotator 2 and the outer rotator 5 need only be relatively rotatable, even if the inner rotator 2 is fixed and the outer rotator 5 rotates, the inner rotator 2 is fixed and the outer rotator 5 rotates outward. The body 5 may be rotated. In some cases, both rotating bodies may rotate at different rotational speeds. A round bar-like or round pipe-like pusher 6 is erected on the upper surface of the outer rotating body 5. The outer rotating body 5 can be rotated by power such as a motor or manually. In the case of manual rotation, the outer rotating body 5 can be provided with a handle protruding outward, and the handle can be operated to rotate.

内側回転体２の上面にはセット具３が立設されている。セット具３は二本の丸棒、丸パイプ等のセット軸８を、空間をあけて並べて立設したものであり、両セット軸８間の空間をセット空間４としてある。セット空間４は曲げ加工する板材１を鉛直に立てた状態（縦向き）にセットするためのものである。セット空間４は上方開口にして板材１を横から抜き差しすることも上から抜き差しすることもできるようにしてある。   A set tool 3 is erected on the upper surface of the inner rotating body 2. The set tool 3 is a set shaft 8 such as two round bars and a round pipe arranged side by side with a space therebetween, and the space between the set shafts 8 is set as a set space 4. The set space 4 is for setting the plate material 1 to be bent in a vertical state. The set space 4 is opened upward so that the plate 1 can be inserted / removed from the side or from above.

前記二本のセット軸８の上部には図１、図３（ａ、ｂ）に示すように保持具９を被せて両セット軸８を一定間隔に保持し、板材１の曲げ加工時にその曲げ力がセット軸８に加わっても両セット軸８間の間隔が広がらないようにしてある。図１の保持具９は円盤状であり、セット軸８を挿通可能な挿通孔１０が横に二つ並んで開口されている。保持具９の形状や構造は図に示すものには限られず、両セット軸８同士の間隔が広がらないように両セット軸８を保持できるものであれば任意のものを用いることができる。この保持具９は両セット軸８の間隔が広がらないものの場合は省略することができる。   As shown in FIGS. 1 and 3A and 3B, the two set shafts 8 are covered with a holder 9 so as to hold the two set shafts 8 at a predetermined interval. Even when a force is applied to the set shaft 8, the distance between the set shafts 8 is not increased. The holder 9 in FIG. 1 has a disk shape, and two insertion holes 10 through which the set shaft 8 can be inserted are opened side by side. The shape and structure of the holder 9 are not limited to those shown in the figure, and any one can be used as long as it can hold both set shafts 8 so that the distance between the set shafts 8 is not widened. The holder 9 can be omitted if the distance between the set shafts 8 is not wide.

外側回転体５の上面には丸棒状、丸パイプ状の押し具６が立設されて外側回転体５と共に回転するようにしてある。この押し具６にはセット軸８よりも径の太いものが使用されている。押し具６は曲げ加工する板材１と当接する部分が円弧状に形成されていれば任意の形状、例えば、棒状やパイプ状ではなく円盤状にすることもできる。   On the upper surface of the outer rotating body 5, a round bar-like or round pipe-like pressing tool 6 is erected so as to rotate together with the outer rotating body 5. The pusher 6 is thicker than the set shaft 8. The pusher 6 can be formed into an arbitrary shape, for example, a disc shape instead of a rod shape or a pipe shape, as long as the portion that comes into contact with the plate material 1 to be bent is formed in an arc shape.
