Description
本発明は、積層体を製造する積層体製造装置及びプレス加工機に関する。 The present invention relates to a laminated body manufacturing apparatus and a press working machine for manufacturing a laminated body.
従来、母材が環状に複数層巻かれた積層体を製造する積層体製造装置が周知である（特許文献１等参照）。この積層体の内周面には、例えば切り欠き等からなる加工形状部が形成されている。この種の積層体製造装置は、例えば母材に切り欠き等の加工を入れながら、これを周状に巻き送りしていくことで、複数の層からなる筒形状積層体を製造する。 Conventionally, a laminated body manufacturing apparatus for manufacturing a laminated body in which a base material is wound in plural layers in an annular shape is well known (see Patent Document 1, etc.). On the inner peripheral surface of this laminated body, a processed shape portion formed of, for example, a notch or the like is formed. A laminated body manufacturing apparatus of this type manufactures a cylindrical laminated body composed of a plurality of layers by, for example, forming a notch or the like in a base material and winding the peripheral material in a circumferential shape.
しかし、前述した工法の場合、母材に切り欠き等の加工を入れた後に母材を環状に加工するので、切欠部とそれ以外とで曲率が変化し、積層体の真円度や径精度を確保することができない問題があった。この対応策としては、例えば母材を環状に加工してから、切欠部を形成する工法が想定される。しかし、この工法の場合、プレスの切り欠き加工で発生する力によって、環状の母材の径が切欠部で広がってしまい、径精度が安定しない可能性があった。 However, in the case of the above-mentioned construction method, since the base material is processed into an annular shape after the base material is processed such as a notch, the curvature changes between the notch and other parts, and the circularity and the diameter accuracy of the laminated body are changed. There was a problem that could not be secured. As a countermeasure against this, for example, a method in which the base material is processed into an annular shape and then the notch is formed is assumed. However, in the case of this construction method, the diameter of the annular base material expands at the notch due to the force generated in the notch processing of the press, and the diameter accuracy may not be stable.
本発明の目的は、形状精度の確保を可能にした積層体製造装置及びプレス加工機を提供することにある。 An object of the present invention is to provide a laminated body manufacturing apparatus and a press working machine capable of ensuring shape accuracy.
前記問題点を解決する積層体製造装置は、プレス加工によって母材に加工形状部を形成するプレス加工機と、前記母材が複数層に積層されてなる層の群を、各層の前記加工形状部の位置が合わされつつ、各層に形成された接合部を介して固定する接合加工機とを備え、前記プレス加工機は、前記母材に前記加工形状部を形成する加工と、前記母材に前記接合部を形成する加工とを同時に実行する。 A laminated body manufacturing apparatus that solves the above problems includes a press machine that forms a machined shape portion in a base material by press working, and a group of layers in which the base material is laminated in a plurality of layers, and the machined shape of each layer. While the positions of the parts are aligned, a joining machine for fixing the joints formed through the respective layers is provided, and the press machine is a process for forming the machined shape part on the base material, and the base material. The process of forming the joint portion is simultaneously performed.
前記問題点を解決するプレス加工機は、金型部によるプレス加工によって母材に加工形状部を形成し、複数層に積層された前記層の群を、各層の前記加工形状部の位置が合わされつつ、各層に形成された接合部を介して固定する積層体製造装置に使用される構成であって、前記金型部は、前記母材に前記加工形状部を形成する加工と、前記母材に前記接合部を形成する加工とを同時に実行する。 A press machine that solves the above-mentioned problems forms a processed shape part on a base material by pressing with a die part, and the positions of the processed shape part of each layer are aligned in a group of layers laminated in a plurality of layers. While being configured to be used in a laminated body manufacturing apparatus for fixing via a joint formed in each layer, the mold part is a process for forming the processed shape part on the base material, and the base material. And the process of forming the joint portion are simultaneously performed.
本発明によれば、積層体において、形状精度を確保することができる。 According to the present invention, shape accuracy can be ensured in a laminated body.

There is. The base material 2 is made of, for example, a strip-shaped steel plate. On the inner peripheral surface of the laminated body 1, a plurality of processed shape portions 4 extending in the height direction of the laminated body 1 (Z-axis direction in FIG. 1) are arranged at equal intervals in the circumferential direction of the inner peripheral surface 5 of the laminated body 1. This example is formed at four places). The processed shape portion 4 is a cutout portion 6 formed by cutting out a part of the base material 2. The upper and lower layers of each layer 3 are fixed to each other via a joint portion 7 formed in each layer 3.
図２に示すように、積層体１を製造する積層体製造装置８は、母材２を巻き取って環状に送る巻き加工機９と、巻き加工後の母材２をプレス加工するプレス加工機１０と、プレス加工後に積層された層状の母材２を固定する接合加工機１１とを備える。巻き加工機９、プレス加工機１０及び接合加工機１１は、一体の装置としてユニット化されている。 As shown in FIG. 2, the laminated body manufacturing apparatus 8 for manufacturing the laminated body 1 includes a winding machine 9 that winds the base material 2 and sends it in an annular shape, and a press working machine that presses the base material 2 after winding. 10 and a joining machine 11 for fixing the layered base materials 2 laminated after pressing. The winding machine 9, the press machine 10, and the joining machine 11 are unitized as an integrated device.
巻き加工機９は、複数の搬送ローラ１２と、環状に加工される母材２の径に応じて可動する可動ローラ１３とを備える。可動ローラ１３は、母材２の径方向（図２の矢印Ａ方向）において位置が切り替わることにより、環状に形成される母材２の径を設定する。 The winding machine 9 includes a plurality of transport rollers 12 and a movable roller 13 that is movable according to the diameter of the base material 2 that is processed into an annular shape. The position of the movable roller 13 is switched in the radial direction of the base material 2 (direction of arrow A in FIG. 2) to set the diameter of the base material 2 formed in an annular shape.
図３に示すように、プレス加工機１０の金型部１４は、固定型１５と、固定型１５に対して可動する可動型１６とを備える。本例のプレス加工機１０、すなわち金型部１４は、母材２に加工形状部４を形成する加工と、母材２に接合部７を形成する加工とを同時に実行する。可動型１６は、母材２の一部分を切断する切断部１７と、母材２を所定圧によって押し出す打出部１８とを備える。打出部１８は、切断部１７の両側に配置されるように一対設けられている。固定型１５には、切断部１７及び打出部１８が通過できる逃げ部１９が形成されている。逃げ部１９は、例えば貫通孔である。プレス加工機１０は、切断部１７によって母材２の縁部に加工形状部４をプレス成形するとともに、一対の打出部１８によって母材２に複数の接合部７をプレス加工する。切欠部６は、母材２の縁部の一部分を切り欠いた形状となっている。 As shown in FIG. 3, the die unit 14 of the press machine 10 includes a fixed die 15 and a movable die 16 movable with respect to the fixed die 15. The press machine 10 of the present example, that is, the die unit 14, simultaneously performs the process of forming the machined shape portion 4 on the base material 2 and the process of forming the bonding portion 7 on the base material 2. The movable die 16 includes a cutting portion 17 that cuts a part of the base material 2 and a punching portion 18 that pushes out the base material 2 with a predetermined pressure. A pair of embossing parts 18 are provided so as to be arranged on both sides of the cutting part 17. The fixed die 15 is formed with an escape portion 19 through which the cutting portion 17 and the embossing portion 18 can pass. The escape portion 19 is, for example, a through hole. The press machine 10 press-forms the machined shape portion 4 on the edge portion of the base material 2 by the cutting portion 17, and presses the plurality of joint portions 7 on the base material 2 by the pair of embossing portions 18. The cutout 6 has a shape obtained by cutting out a part of the edge of the base material 2.
図４に示すように、接合加工機１１は、層状に複数周積み重ねられた層３の群を載置する座部２０と、機械的な衝撃を接合部７に与えて各層３を固定するヘッド部２１とを備える。ヘッド部２１は、座部２０に対して上下方向に移動する。接合加工機１１は、カシメ加工によって層３の群を一体に固定するカシメ機である。ヘッド部２１には、カシメ加工において、上下層同士で位置決めされた接合部７に上方から押圧する力を加える棒状のツール２２が一対形成されている。接合加工機１１は、積層された複数の層３の群を、各層３の加工形状部４の位置が合わされながら、各層３に各々形成された接合部７を介して固定する。 As shown in FIG. 4, the joining machine 11 includes a seat portion 20 on which a group of layers 3 stacked in a plurality of layers is placed, and a head for applying a mechanical shock to the joining portion 7 to fix each layer 3. And a section 21. The head portion 21 moves up and down with respect to the seat portion 20. The joining machine 11 is a caulking machine that integrally fixes the group of layers 3 by caulking. The head portion 21 is formed with a pair of rod-shaped tools 22 for applying a pressing force from above to the joint portion 7 positioned between the upper and lower layers in the crimping process. The joining machine 11 fixes a group of a plurality of laminated layers 3 via the joining portions 7 formed on each layer 3 while aligning the positions of the processed shape portions 4 of each layer 3.
次に、図２、図５〜図７を用いて、本実施形態の積層体製造装置８及びプレス加工機１０の作用について説明する。
図５（ａ）に示すように、帯状の母材２は、巻き加工機９によって環状に巻かれながらプレス加工機１０に搬送される。図５（ｂ）に示すように、母材２が所定量搬送されると、母材２の搬送が一旦停止され、プレス加工機１０の可動型１６が下方に作動することで母材２がプレス加工される。本例の場合、プレス加工において、母材２に加工形状部４を形成する加工と、母材２に接合部７を形成する加工とが、同時に実行される。すなわち、このプレス加工時、切断部１７によって母材２に切欠部６が形成され、打出部１８によって一対の接合部７が形成される。プレス加工機１０は、環状に巻かれながら搬送されてくる母材２に対し、周方向に等間隔で切欠部６が形成されるように、母材２のプレス加工を周期的に繰り返す。
Next, the operation of the laminated body manufacturing apparatus 8 and the press working machine 10 of this embodiment will be described with reference to FIGS. 2 and 5 to 7.
As shown in FIG. 5A, the strip-shaped base material 2 is conveyed to the press processing machine 10 while being wound in an annular shape by the winding processing machine 9. As shown in FIG. 5B, when the base material 2 is conveyed by a predetermined amount, the conveyance of the base material 2 is temporarily stopped, and the movable die 16 of the press working machine 10 is operated downward to move the base material 2 Pressed. In the case of this example, in the press working, the working of forming the machined shape portion 4 on the base material 2 and the working of forming the bonding portion 7 on the base material 2 are simultaneously performed. That is, during this press working, the notch 6 is formed in the base material 2 by the cutting portion 17, and the pair of joints 7 is formed by the punching portion 18. The press machine 10 periodically repeats the press work of the base material 2 so that the cutouts 6 are formed at equal intervals in the circumferential direction on the base material 2 that is conveyed while being wound in an annular shape.
図６（ａ）、（ｂ）の各々の部分拡大図に示すように、接合部７は、母材２の片方の面側が穴形状となったボス状の突起からなる。ボス状の突起をなす接合部７は、凸部２７及び凹部２８を有した形状となっている。接合部７は、例えば円筒状の突起であって、切欠部６の両側に一対配置されている。接合部７の凹部２８は、開口が円形状となっている。 As shown in the partial enlarged views of FIGS. 6A and 6B, the joint portion 7 is composed of a boss-shaped protrusion having a hole shape on one surface side of the base material 2. The joint portion 7 forming a boss-like protrusion has a shape having a convex portion 27 and a concave portion 28. The joint portions 7 are, for example, cylindrical protrusions, and are arranged in pairs on both sides of the cutout portion 6. The recess 28 of the joint 7 has a circular opening.
ここで、図２の部分拡大図に示すように、母材２に切欠部６をプレス加工した場合、母材２において加工の応力Ｆが発生する。この応力Ｆは、切欠部６から母材２の径方向外側に向かって発生する。母材２に応力Ｆが発生してしまうと、母材２の径が広がってしまう形状変化が生じ、円形状が安定しない可能性に繋がる。しかし、本例の場合、プレス加工において切欠部６及び接合部７を同時に形成するので、接合部７によって応力Ｆを相殺することが可能となる。よって、母材２に切欠部６をプレスによって形成しても、母材２の径の変化が防止される。 Here, as shown in the partially enlarged view of FIG. 2, when the notch 6 is pressed in the base material 2, a processing stress F is generated in the base material 2. This stress F is generated from the cutout portion 6 toward the radially outer side of the base material 2. When the stress F is generated in the base material 2, the diameter of the base material 2 is expanded, and the shape of the base material 2 is changed. However, in the case of this example, since the notch 6 and the joint 7 are simultaneously formed in the press working, the stress F can be canceled by the joint 7. Therefore, even if the notch 6 is formed in the base material 2 by pressing, the change in the diameter of the base material 2 is prevented.
図６（ａ）に示すように、プレス加工された母材２が複数周巻かれて層状とされた後、接合加工機１１は、この層状の母材２に対してカシメ加工を実行する。カシメ加工は、例えば母材２が１周分積層される度に毎回実施されることが好ましい。また、カシメ加工時、最下層の層３の接合部７は、座部２０の上面に複数形成された溝３０に各々嵌合される。 As shown in FIG. 6A, after the press-processed base material 2 is wound a plurality of times around to form a layer, the joining machine 11 performs a crimping process on the layered base material 2. It is preferable that the crimping is performed, for example, every time the base material 2 is laminated for one round. Further, at the time of caulking, the joint portions 7 of the lowermost layer 3 are fitted into the grooves 30 formed in plural on the upper surface of the seat portion 20, respectively.
図６（ｂ）に示すように、接合加工機１１は、カシメ加工時、座部２０上に層状の母材２を乗せ、ヘッド部２１を下方に作動させる。このとき、ヘッド部２１のツール２２を、最上層に位置する接合部７の凹部２８に挿し込んで上から押し込むことにより、積層方向に並ぶ接合部７同士を固定する。これにより、上の層３の接合部７の凸が、下の層３の凹にきつく嵌め込まれ、層３の群が一体に固定される。 As shown in FIG. 6B, the joining machine 11 places the layered base material 2 on the seat portion 20 and operates the head portion 21 downward during caulking. At this time, the tool 22 of the head portion 21 is inserted into the concave portion 28 of the joining portion 7 located in the uppermost layer and pushed from above to fix the joining portions 7 arranged in the stacking direction. As a result, the convex portion of the joint portion 7 of the upper layer 3 is tightly fitted into the concave portion of the lower layer 3, and the group of layers 3 is integrally fixed.
図７に示すように、接合加工機１１は、座部２０に載置される層３の数が増加していくにつれて、座部２０が下方に移動する。すなわち、層３が順次積層されていくにつれて、接合加工機１１の座部２０が下方に移動することにより、座部２０の高さ方向の位置が調整される。そして、一連の巻き工程、プレス工程及びカシメ加工が実施されることにより、複数の層３が積層方向に連なった積層体１が製造される。 As shown in FIG. 7, in the joining machine 11, the seat portion 20 moves downward as the number of layers 3 placed on the seat portion 20 increases. That is, as the layers 3 are sequentially stacked, the seat portion 20 of the joining machine 11 moves downward, so that the position of the seat portion 20 in the height direction is adjusted. Then, a series of winding steps, pressing steps, and caulking are performed to manufacture the laminated body 1 in which the plurality of layers 3 are continuous in the laminating direction.
上記実施形態の積層体製造装置８及びプレス加工機１０によれば、以下のような効果を得ることができる。
プレス加工時、切欠部６の加工と接合部７の加工とを同時に実行するようにした。このため、プレス加工時、母材２において切欠部６の付近に加工の応力Ｆが発生したとしても、プレス加工時に同時形成された接合部７によって、この応力Ｆを相殺することが可能となる。これにより、母材２には、切欠部６の形成によって生じる応力Ｆに起因した変形が生じ難くなる。よって、積層体１において、形状精度を確保することができる。
According to the laminated body manufacturing apparatus 8 and the press working machine 10 of the above-described embodiment, the following effects can be obtained.
At the time of press working, the working of the cutout portion 6 and the working of the joint portion 7 are simultaneously performed. Therefore, even if a stress F is generated in the vicinity of the notch 6 in the base material 2 during press working, this stress F can be offset by the joint portion 7 formed simultaneously during press working. .. As a result, the base material 2 is less likely to be deformed due to the stress F generated by the formation of the cutout portion 6. Therefore, in the laminated body 1, the shape accuracy can be ensured.
加工形状部４は、母材２の縁部に形成された切欠部６である。接合部７は、母材２の片方の面側に凹部２８を有するボス状の突起である。プレス加工機１０は、ボス状の突起からなる接合部７を切欠部６の両側に一対形成する。これにより、プレス加工によって切欠部６を母材２に設けた場合に母材２に発生する応力Ｆを、ボス状の突起からなる一対の接合部７によって相殺することが可能となる。よって、簡易な形状の複数の接合部７によって、応力Ｆを効果的に相殺することができる。 The processed shape portion 4 is a cutout portion 6 formed in the edge portion of the base material 2. The joint portion 7 is a boss-shaped protrusion having a recess 28 on one surface side of the base material 2. The press machine 10 forms a pair of joints 7 formed of boss-shaped protrusions on both sides of the notch 6. As a result, the stress F generated in the base material 2 when the notch 6 is formed in the base material 2 by press working can be offset by the pair of joints 7 formed of boss-shaped projections. Therefore, the stress F can be effectively canceled by the plurality of joints 7 having a simple shape.
プレス加工機１０は、環状に巻き送りされた母材２をプレス加工する。接合加工機１１は、母材２に巻き送りされて複数層の筒形状に形成された層３の群を、各層３の切欠部６の位置が合わされつつ、各層３に各々形成された接合部７を介して固定する。よって、径の形状精度が高い積層体１を製造することができる。 The press processing machine 10 presses the base material 2 wound in a ring shape. The joining machine 11 joins a group of layers 3 formed into a tubular shape of a plurality of layers by being wound around the base material 2 while the positions of the notches 6 of the layers 3 are aligned, and the joining portions formed on the layers 3 respectively. Fix through 7. Therefore, it is possible to manufacture the laminated body 1 having a high precision in the shape of the diameter.
