Abstract
Description
本開示は、金属製の帯板が渦巻き状に成形された渦巻きばねの製造方法に関する。 The present disclosure relates to a method of manufacturing a spiral spring in which a metal strip is spirally formed.
例えば、特許文献１に記載の発明では、２つ以上のローラ状の渦巻きツールにて金属製の帯板を渦巻き状に成形している。 For example, in the invention described in Patent Document 1, a metal strip is formed into a spiral shape by two or more roller-shaped spiral tools.
特許文献１に記載の発明では、大きな渦巻きばね、つまり板厚及び周長（帯板の長手方向寸法）が大きい渦巻きばねを製造することが難しい。本開示は、左記点に鑑み、大きな渦巻きばねであっても製造可能な渦巻きのばねの製造方法の一例を開示する。 In the invention described in Patent Document 1, it is difficult to manufacture a large spiral spring, that is, a spiral spring having a large plate thickness and peripheral length (longitudinal dimension of the strip). In view of the above left point, the present disclosure discloses an example of a method for manufacturing a spiral spring that can manufacture a large spiral spring.
金属製の帯板（２）が渦巻き状に成形された渦巻きばねの製造方法は、例えば、以下の手順（作業工程）のうち少なくとも１つを備えることが望ましい。
すなわち、当該手順は、帯板（２）の長手方向一端側及び可撓性を有する金属製のスペーサ（１２）を、円柱状又は円筒状の芯金（１１）に係止した状態で、スペーサ（１２）が帯板（２）間に位置するように、当該帯板（２）をスペーサ（１２）と共に芯金（１１）に巻き付け、巻き付けが終了したときに、スペーサ（１２）及び芯金（１１）を帯板（２）から取り外すことである。
The method for manufacturing a spiral spring in which the metal strip (2) is formed in a spiral shape preferably includes at least one of the following procedures (working steps).
That is, the procedure is such that the spacer (12) in the longitudinal direction of the strip (2) and the flexible metal spacer (12) are locked to the cylindrical or cylindrical core metal (11). The strip (2) is wound around the core metal (11) together with the spacer (12) so that the (12) is located between the strips (2), and when the winding is completed, the spacer (12) and the core metal (11) is to be removed from the strip (2).
これにより、渦巻きばねの製造する者（製造装置も含む。以下、製造者という。）は、例えば、帯板（２）とスペーサ（１２）とが密着するように、帯板（２）とスペーサ（１２）とを芯金（１１）に巻き付けた後、スペーサ（１２）を取り外すことにより、隣り合う帯板（２）間に容易に隙間を確保しながら当該帯板（２）を渦巻き状に成形することができ得る。したがって、製造者は、板厚及び周長が大きい場合であっても渦巻きばねを確実に製造することができ得る。 As a result, a person who manufactures the spiral spring (including a manufacturing apparatus; hereinafter, referred to as a manufacturer) can, for example, make the strip plate (2) and the spacer (12) in close contact with each other. After winding (12) and the core metal (11) around the core metal (11), the spacer (12) is removed to make the strip plate (2) spiral while ensuring a gap between the adjacent strip plates (2) easily. It can be molded. Therefore, the manufacturer can reliably manufacture the spiral spring even when the plate thickness and the peripheral length are large.
なお、帯板（２）をスペーサ（１２）と共に芯金（１１）に巻き付ける際には、巻き付けられる前の帯板（２）を加熱することが望ましい。これにより、製造者は、確実に帯板（２）を渦巻き状に成形でき得る。 When the strip plate (2) is wound around the core metal (11) together with the spacer (12), it is desirable to heat the strip plate (2) before being wound. This allows the manufacturer to reliably form the strip (2) into a spiral shape.

（第１実施形態）
本実施形態は、図１に示される渦巻きばね１の製造方法及び製造装置に本開示に係る製造方法及び製造装置の一例が適用されたものである。
(First embodiment)
In this embodiment, an example of the manufacturing method and manufacturing apparatus according to the present disclosure is applied to the manufacturing method and manufacturing apparatus of the spiral spring 1 shown in FIG.
渦巻きばね１は、金属製の帯板２が渦巻き状に成形されたばねである。当該渦巻きばね１は、例えば、板厚約１１ｍｍ、板幅６０ｍｍ、直径約５００ｍｍ、帯板長さ約５ｍ超の大型の渦巻きばねである。 The spiral spring 1 is a spring in which a metal strip 2 is spirally formed. The spiral spring 1 is, for example, a large spiral spring having a plate thickness of about 11 mm, a plate width of 60 mm, a diameter of about 500 mm, and a strip plate length of more than about 5 m.
＜製造装置の概要＞
製造装置１０は、図２に示されるように、芯金１１及び加熱器１３等を少なくとも備える。芯金１１は、帯板２の長手方向一端側及び金属製のチェーン１２が係止される円柱状又は円筒状の部材である。
<Outline of manufacturing equipment>
As shown in FIG. 2, the manufacturing apparatus 10 includes at least a core metal 11 and a heater 13. The cored bar 11 is a cylindrical or cylindrical member to which the one end side of the strip plate 2 in the longitudinal direction and the metal chain 12 are locked.
芯金１１は、電動モータ等の回転機（図示せず。）により回転駆動される。このため、芯金１１が回転すると、図３に示されるように、チェーン１２が帯板２間に位置した状態で、帯板２がチェーン１２と共に巻かれていく。なお、チェーン１２は、可撓性を有する金属製のスペーサの一例である。 The cored bar 11 is rotationally driven by a rotating machine (not shown) such as an electric motor. Therefore, when the cored bar 11 rotates, as shown in FIG. 3, the strip 12 is wound between the strips 2 while the chain 12 is located between the strips 2. The chain 12 is an example of a flexible metal spacer.
加熱器１３は、芯金１１に巻き付けられる前の帯板２を加熱する。加熱器１３による加熱は、帯板２を芯金１１に巻き付けることを可能にするためである。なお、本実施形態に係る加熱器１３は、誘導加熱方式の加熱器である。 The heater 13 heats the strip plate 2 before being wound around the core metal 11. The heating by the heater 13 is to enable the strip 2 to be wound around the cored bar 11. The heater 13 according to the present embodiment is an induction heating type heater.
＜製造方法の概要（図２及び図３参照）＞
作業者又は製造装置（以下、作業者等という。）は、先ず、帯板２の長手方向一端側及びチェーン１２を芯金１１に係止する。次に、作業者等は、チェーン１２を帯板２間に位置させた状態で、芯金１１を回転させる。つまり、作業者等は、帯板２を加熱しながら、当該帯板２をチェーン１２と共に芯金１１に巻き付けていく。
<Outline of manufacturing method (see FIGS. 2 and 3)>
An operator or a manufacturing apparatus (hereinafter, referred to as an operator, etc.) first locks one end side of the strip 2 in the longitudinal direction and the chain 12 to the core metal 11. Next, the worker or the like rotates the core metal 11 with the chain 12 positioned between the strips 2. That is, an operator or the like winds the strip 2 around the core 11 together with the chain 12 while heating the strip 2.
そして、上記巻き付け作業が終了したときに、チェーン１２及び芯金１１を渦巻き状に成形された帯板２から取り外す。その後、作業者等は、成形が終了した帯板２、つまり渦巻きばね１に熱処理等の後工程を施す。 Then, when the winding operation is completed, the chain 12 and the cored bar 11 are removed from the spirally shaped strip plate 2. Then, an operator or the like performs a post-process such as heat treatment on the band plate 2 that has been formed, that is, the spiral spring 1.
＜本実施形態に係る製造方法及び製造装置の特徴＞
作業者等は、例えば、帯板２とチェーン１２とが密着するように、帯板２とチェーン１２とを芯金１１に巻き付けた後、チェーン１２を取り外すことにより、隣り合う帯板２間に容易に隙間を確保しながら当該帯板２を渦巻き状に成形することができ得る。
<Characteristics of the manufacturing method and the manufacturing apparatus according to the present embodiment>
An operator or the like, for example, winds the strip plate 2 and the chain 12 around the core metal 11 so that the strip plate 2 and the chain 12 come into close contact with each other, and then removes the chain 12 so that the space between the adjacent strip plates 2 is increased. It is possible to easily form the strip 2 into a spiral shape while ensuring the gap.
したがって、作業者等は、板厚及び帯板長さが大きい場合であっても渦巻きばね１を確実に製造することができ得る。
帯板２をチェーン１２と共に芯金１１に巻き付ける際には、巻き付けられる前の帯板２を加熱する。これにより、作業者等は、確実に帯板２を渦巻き状に成形でき得る。
Therefore, an operator or the like can reliably manufacture the spiral spring 1 even when the plate thickness and the strip plate length are large.
When winding the strip 2 together with the chain 12 around the core metal 11, the strip 2 before being wound is heated. Thereby, an operator or the like can surely form the strip 2 into a spiral shape.
（その他の実施形態）
上述の実施形態では、スペーサとして金属製のチェーン１２を用いた。しかし、本開示はこれに限定されるものではない。

In the above-described embodiment, the metal chain 12 is used as the spacer. However, the present disclosure is not limited to this.
上述の実施形態では、帯板２をチェーン１２と共に芯金１１に巻き付ける際には、巻き付けられる前の帯板２を加熱する加熱工程を備えていた。しかし、本開示はこれに限定されるものではない。すなわち、当該開示は、例えば、上記の加熱工程を廃止された製造方法又は製造装置であってもよい。 In the above-described embodiment, when the strip 2 is wound around the cored bar 11 together with the chain 12, a heating step of heating the strip 2 before being wound is provided. However, the present disclosure is not limited to this. That is, the present disclosure may be, for example, a manufacturing method or a manufacturing apparatus in which the heating step is abolished.
さらに、本開示は、上述の実施形態に記載された開示の趣旨に合致するものであればよく、上述の実施形態に限定されるものではない。したがって、上述した複数の実施形態のうち少なくとも２つの実施形態が組み合わせられた構成、又は上述の実施形態において、図示された構成要件もしくは符号を付して説明された構成要件のうちいずれかが廃止された構成でもよい。 Further, the present disclosure is not limited to the above-described embodiments, as long as it matches the spirit of the disclosure described in the above-described embodiments.
