本発明はトランスフア方法に関するものであ
る。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a transfer method.
トランスフア方法とはプレスにブランク材（素
材）等を供給する方法のことである。 The transfer method is a method of supplying a blank material (material), etc. to a press.
多種少量生産の傾向にある現在、同一のプレス
で大小さまざまな製品を取扱うことが要求され
る。しかし、プレス機械は、ベツドの中心近傍で
加圧することを想定して設計されていること、他
方、ブランク等はブランクの軸心方向にクランプ
して搬送すると安定性が確保できることなどの理
由から、プレスで取扱う製品はその大きさで制限
されてしまう。逆にいえば、取扱う製品によつて
プレスは可成大形のものにせざるを得なくなる。 Currently, there is a trend toward high-mix, low-volume production, which requires the same press to handle products of various sizes. However, press machines are designed with the assumption that pressure is applied near the center of the bed, and on the other hand, stability can be ensured by clamping blanks in the axial direction of the blank, etc. The products that can be handled by a press are limited by their size. Conversely, depending on the product being handled, the press must be of a manageable size.
本発明はこの問題を解決するため、すなわち、
プレスの大きさの割には大きな製品を取扱うこと
ができる、プレスに使用されるトランスフア方法
を提供せんとするものである。 The present invention solves this problem, namely:
It is an object of the present invention to provide a transfer method used in a press that can handle large products relative to the size of the press.
以下、本発明を本発明による一実施例の装置で
ある図面に基づいて詳説する。 DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described in detail below with reference to the drawings, which are an embodiment of an apparatus according to the present invention.

ンクランプの動作を与える構造となつている。 In FIGS. 1 and 3, a transfer unit 3 is fixed to the bed 2 and column 1 of the press, and a known transfer drive mechanism is incorporated inside. The slider 5 is connected to a transfer drive mechanism and is structured to perform advance and return movements. An auxiliary slider 8 is rotatably attached to the upper part of the slider 5 with a pin 9. The auxiliary slider 8 is fixed to the slider 5 at a desired inclination. In this embodiment, the structure is such that it is tightened with bolts.
The block 10 is slidably fitted into the groove of the auxiliary slider 8, and the feed bar 6 is rotatably held by a pin 11. Clamp unit 13 is in column 1
Alternatively, it may be fixed to the transfer unit 3 to slidably hold the feed bar 6 and provide clamping/unclamping operations.
以下、動作について説明する。 The operation will be explained below.

バンスb′、アンクランプc′、リターンd′の長方形
の軌跡であつた。 In FIG. 2, when handling large products, the center line of the mold is inclined with respect to the center line of the press bed. Similarly, the center line of the auxiliary slider 8 is inclined with respect to the center line of the slider 5, and the center line of the mold and the center line of the auxiliary slider are set to be substantially parallel. If you drive in this condition,
The feed bar 6 has clamp a, advance b, unclamp c, and return d as shown in Fig. 5.
Draw the locus of the parallelogram. In the conventional transfer device, the locus was a rectangular shape of clamp a', advance b', unclamp c', and return d' as shown in FIG.
本発明は以上のように搬送物を送り方向に対し
適宜の傾斜角度をもたせてクランプ・アンクラン

て大きな製品を取扱う場合、プレスのベツドの中
心近傍で加圧し、ブランク材等をその軸心方向に
クランプして搬送できるので、送り動作が安定し
ており、プレスにも無理な荷重をかけることもな
いこと、比較的小さな製品を取扱う場合には従来
と同じ送り動作に切換えることができることなど
の長所がある。 As described above, the present invention is a method of clamping and unclamping the conveyed object at an appropriate inclination angle with respect to the feeding direction. Since the blank material can be conveyed by clamping it in the axial direction, the feeding operation is stable and there is no need to apply excessive load to the press. It has the advantage of being able to switch to the same feeding operation as the conventional one.

法。1 A pair of feed bars of a transfer press installed parallel to each other in a horizontal plane have an advance return motion that reciprocates at a feeding pitch in the longitudinal direction, and a direction tilted at an arbitrary angle within the same horizontal plane from the horizontal direction perpendicular to the longitudinal direction. Clamping and unclamping motions of approaching and separating parallel to each other are applied to create a conveying motion that draws a parallelogram, and a pair of fingers attached to a pair of feed bars facing the above-mentioned inclined direction is used to direct the press in that direction. A transfer method characterized in that the object is sequentially conveyed to the molds of each process arranged in the feeding direction, with the inclined direction being the inclined direction.
