Description

本発明は、外形の同一または異なる板材を厚み方向に組み合わせてなる積層体に係り、金型を用いて外形の異なる板材を順次打抜いて形成するとともに、打抜かれた板材同士をかしめにより一体的に接合して積層体を製造する方法およびその製造装置に関する。 The present invention relates to a laminate formed by combining plate materials having the same or different outer shapes in the thickness direction, and is formed by sequentially punching plate materials having different outer shapes by using a mold, and integrally stamping the plate materials by caulking. The present invention relates to a method of manufacturing a laminated body by bonding to a substrate and a manufacturing apparatus thereof.
従来、外形の異なる板材を組み合わせて積層体を形成する場合、板材を個別に金型で打ち抜きを行ない、金型外にてそれぞれの板材を位置合わせして積層していたが、この方法では板材同士を別工程で組み合わせるため、積層した際の精度が悪く、また、組み合せ作業に手間と時間を要するため生産性も低いという問題がある。
そこで、前記課題を解決するものとして、特許文献1のように、縦列に並べた金型に帯状材料を搬送させつつ各種外形の板材を打抜くとともに、これらを最終工程(金型)にてかしめにより一体的に接合して積層する方法および装置が知られている。
Conventionally, when a laminate is formed by combining plate materials having different external shapes, the plate materials are individually punched with a mold, and the respective plate materials are aligned and laminated outside the mold. Since they are combined in separate steps, there is a problem that the accuracy in stacking is poor, and the productivity is low because labor and time are required for the combination work.
In order to solve the above problems, as in Patent Document 1, while punching plate materials of various external shapes while transporting the belt-like material to the dies arranged in tandem, these are caulked in the final process (die). And a method and apparatus for integrally joining and stacking are known.
特開2002−35866号公報JP 2002-35866 A
特許文献1の方法は、帯状材料からそれぞれ外形の異なる板材をプッシュバックを利用して予め打ち抜いておき、これを材料に保持した状態で搬送して最終工程で外形抜きと同時に積層を行うようにしており、特に外形抜きにおいては、板材の異なる外形に対応するため、複数個の外形抜きパンチをパンチホルダーに備え、このホルダーを軸周りに回動させて選択的にパンチを稼動させて外形抜きを行っている。また、その際、板材を下面より支持する支持装置が板材の積層分だけ下降するように構成されている。 In the method of Patent Document 1, plate materials having different external shapes are punched in advance from a band-shaped material using a pushback, and are transported in a state of being held in the material, and are laminated at the same time as the external shape is removed in the final process. Especially in the case of outline removal, in order to cope with different outlines of the plate material, a plurality of outline punches are provided in the punch holder and the punch is selectively operated by rotating this holder around the axis. It is carried out. At that time, the support device for supporting the plate material from the lower surface is configured to descend by the amount of the laminated plate material.
しかしながら、この特許文献1記載の方法では板材を積層する際に、側面からの支持がない状態で板材の材料からの切離しと積層とを同時に行うため、少しでもバランスが崩れるとかしめの凸凹位置が合わずに積層不良となる。また、この装置では、板材の外形に合わせて外形抜きパンチを用意しなければならず、またこれらのパンチを選択して稼動させる機構のため装置構造が複雑である。また、外形抜きパンチを変更する際の切替えとそれに合わせたプレススピードの調整や支持装置を下降させるタイミングなど、同期制御も難しくなるという問題も抱えている。
さらにまた、すべての種類の板材にプッシュバックを行うため、板材の形状によっては反りが発生し、他の板材とのかしめの凸凹位置が合わずに積層不良を発生させる可能性も高いという問題がある。
However, in the method described in Patent Document 1, when laminating the plate material, since the separation from the material of the plate material and the lamination are performed at the same time without support from the side surface, if the balance is slightly broken, the caulking uneven position is It does not match, resulting in poor stacking. Further, in this apparatus, it is necessary to prepare outer punches according to the outer shape of the plate material, and the structure of the apparatus is complicated because of the mechanism for selecting and operating these punches. In addition, there is a problem that it is difficult to perform synchronous control, such as switching when changing the punch with the outer shape, adjusting the press speed accordingly, and lowering the support device.
Furthermore, since all types of plate materials are pushed back, warping may occur depending on the shape of the plate material, and there is a high possibility of causing poor stacking due to misalignment positions of caulking with other plate materials. is there.
本発明はかかる事情に鑑みてなされたもので、積層する上下の板材でかしめの凸凹位置がズレることもなく正確に位置合わせができて積層不良の発生がなくなり、装置の機構や制御が複雑になることもない積層体の製造方法およびその製造装置を提供することを目的とする。 The present invention has been made in view of such circumstances, and it is possible to accurately align the upper and lower plate members to be stacked without causing the misalignment of the caulking, so that the occurrence of stacking faults is eliminated, and the mechanism and control of the apparatus are complicated. It aims at providing the manufacturing method of the laminated body which does not become, and its manufacturing apparatus.

2〜4番目の板材14〜16の形成部に対しては、(B)の加工ステーションでかしめ突起19が形成される。そして、帯状材料10は順次間欠送りされて、1番目の板材13の形成部を(C)の加工ステーションに、2番目の板材14の形成部を(D)の加工ステーションに、3番目の板材15の形成部を(E)の加工ステーションに、4番目の板材16の形成部を(F)の加工ステーションに位置させる。この間、(C)〜(F)の加工ステーションは作動しない。帯状材料10がこのようになった状態で、(C)〜(F)の加工ステーションの各パンチ20、24、28、32を作動させる。(C)〜(F)の加工ステーションは同時に作動させてもよいが、順次または(A)〜(F)の各加工ステーションを群に分けて作動させてもよい。 For the formation portions of the second to fourth plate members 14 to 16, the caulking projections 19 are formed at the processing station (B). Then, the belt-like material 10 is intermittently fed in sequence, and the formation portion of the first plate 13 is used as the processing station (C), the formation portion of the second plate 14 is used as the processing station (D), and the third plate. The forming portion 15 is positioned at the processing station (E), and the forming portion of the fourth plate 16 is positioned at the processing station (F). During this time, the processing stations (C) to (F) do not operate. With the belt-like material 10 in this state, the punches 20, 24, 28, 32 of the processing stations (C) to (F) are operated. The processing stations (C) to (F) may be operated simultaneously, but the processing stations (A) to (F) may be operated in sequence or in groups.
(C)の加工ステーションを作動させることによって、前述のように、全抜きまたは半抜きした1番目の板材13を分離押込み加工または非分離押込み加工して帯状材料10内に保持する。(D)〜(F)の加工ステーションを作動させることによって、2〜4番目の板材14〜16を上側のダイ23、27、31の内側に保持する。
この状態で、帯状材料10を1ステーション分だけ順送りする。これによって、1番目の板材13が(D)の加工ステーションに移動することになるので、(D)の加工ステーションの積層パンチ25を下降させて、板材14を板材13の上にかしめ積層する。
By operating the processing station (C), as described above, the first plate member 13 that has been completely or half-extracted is held in the band-shaped material 10 by performing separate pressing processing or non-separating pressing processing. By operating the processing stations (D) to (F), the second to fourth plate members 14 to 16 are held inside the upper dies 23, 27, and 31.
In this state, the belt-shaped material 10 is sequentially fed by one station. As a result, the first plate 13 is moved to the processing station (D), and the stacking punch 25 of the processing station (D) is lowered, and the plate 14 is caulked and stacked on the plate 13.
この後、帯状材料10を1ステーション分だけ順送りして、板材14が積層された板材13を(E)の加工ステーションに移動させる。そして、積層パンチ29を下降して板材15を板材14の上にかしめ積層する。そして、帯状材料10を1ステーション順送りして、板材15、14が載った板材13を(F)の加工ステーションに移動させ、積層パンチ33を作動させて板材16を板材15の上にかしめ積層し、帯状材料10に半固定された積層体17が形成される。なお、以上の状態は図1の最下段に示している。 Thereafter, the belt-like material 10 is sequentially fed by one station, and the plate material 13 on which the plate material 14 is laminated is moved to the processing station (E). Then, the laminating punch 29 is lowered and the plate material 15 is caulked and laminated on the plate material 14. Then, the belt-like material 10 is sequentially fed by one station, the plate material 13 on which the plate materials 15 and 14 are placed is moved to the processing station (F), the lamination punch 33 is operated, and the plate material 16 is caulked and laminated on the plate material 15. A laminated body 17 semi-fixed to the belt-like material 10 is formed. The above state is shown at the bottom of FIG.
そして、帯状材料10を1ステーション分だけ順送りして、帯状材料10に半固定された積層体17を(G)の加工ステーションに移動させ、切り離しパンチ35とダイ36を用いて、積層体17をダイ36内に抜き落とす。
これによって、積層体17が完成する。この状態では、かしめ孔18およびかしめ突起19が形成された板材13〜16の形成部が、それぞれ(C)〜(F)の加工ステーションに並ぶことになり、(C)〜(F)の加工ステーションで、以上説明した動作を行うことによって、次の積層体17が形成される。
なお、前記実施の形態においては、積層パンチ25、29、33の下端面は平面状であったが、各板材14、15、16に形成されたかしめ突起19(半抜きかしめ)の窪みに嵌入する突起(ダボ)を設けることも可能であり、これによって各板材13〜16のかしめ積層を確実に行うことができる。
Then, the belt-like material 10 is sequentially fed by one station, the laminated body 17 semi-fixed to the belt-like material 10 is moved to the processing station (G), and the laminated body 17 is removed using the separation punch 35 and the die 36. Pull out into the die 36.
Thereby, the laminated body 17 is completed. In this state, the formation portions of the plate materials 13 to 16 on which the caulking holes 18 and the caulking protrusions 19 are formed are arranged in the processing stations (C) to (F), respectively, and the processing of (C) to (F) is performed. By performing the operation described above at the station, the next laminate 17 is formed.
In the above-described embodiment, the lower end surfaces of the lamination punches 25, 29, and 33 are flat, but they are fitted into the recesses of the caulking protrusions 19 (half punched caulking) formed on the plate members 14, 15, and 16. It is also possible to provide projections (doughs) to be performed, whereby the plate members 13 to 16 can be surely laminated by caulking.
