本発明は高速プレスにおいて、スライド及び上型の往復
運動により機枠に与えられる不平衡力を平衡させる装置
に関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a device for balancing unbalanced forces applied to a machine frame due to reciprocating motion of a slide and an upper die in a high-speed press.

本発明はこの欠点を除去し、高速プレスの運転時の振動
を少くする平衡装置を提供せんとするものである。Conventionally, as a balance device for the movement of the slide and upper die in a press, a balance wheel is attached to the crankshaft, or an eccentric part is added in the opposite direction to the eccentric part of the crank, and the balance is adjusted in the opposite direction of the slide. There is also a method of swinging weights, and a balancing device in which two gears are meshed with a crankshaft and a subshaft parallel to it, each with a balance weight having the same number of teeth and the same phase. A dynamic unbalanced force is generated in a direction perpendicular to the direction of movement of the slide, and the resulting vibrations on the machine frame cannot be ignored, especially in the case of high-speed presses.The present invention eliminates this drawback. However, it is an object of the present invention to provide a balancing device that reduces vibrations during operation of a high-speed press.
本発明を一実施例の装置の図面を参照として説明すれば

に固着したラック８と噛み合はされている。The present invention will be described with reference to a drawing of an embodiment of the device, in which racks 2 are attached to both sides of a slide 1, and the racks 2
A small-diameter pinion 3 that meshes with the frame 5 and a large-diameter pinion 4 fixed concentrically are pivotally connected to a pin 6 fixed to the frame 5, and the large-diameter pinion 4 is guided by the frame 5 and mounted so as to be movable up and down. Balance weight 7 with weight G each
The rack 8 is engaged with the rack 8 which is fixed to the rack 8.
従ってスライド１が上下動すると、ラック２、ピニオン
３、ピニオン４、及びラック８を介してバランスウェイ
ト７はスライド１の運動方向と逆な方向にスライド１の

重量２Ｇをスライド１及び上型９を含めた重量Ｗに対し
、同一割合で軽量としたものにして、両者の運動エネル

ように設計されているものである。Therefore, when the slide 1 moves up and down, the balance weight 7 moves through the rack 2, pinion 3, pinion 4, and rack 8 in a direction opposite to the direction of movement of the slide 1. Since it moves at a speed faster than the ratio of It is designed to make the kinetic energy of both the same and maintain a dynamic equilibrium between the two.
従ってスライド１か昇降するとラック２ピニオン３ピニ
オン４ラツク８を介してバランスウェイト７がスライド

の振動を少ならしめることができる。Therefore, when the slide 1 is raised or lowered, the balance weight 7 moves in the opposite direction to the slide 1 via the rack 2, pinion 3, pinion 4, and rack 8, so that a mutually balanced state can be maintained at all times, and vibrations of the machine frame can be reduced.

業を行わせることのできる平衡装置である。The present invention has the above-described structure and function, and uses the pinions 3 and 4 to increase the speed of the balance weight 7 relative to the movement speed of the slide 1. Therefore, the weight of the balance weight 7 can be reduced. However, the overall structure is simple and completely symmetrical, and unbalance can be removed, so that stable press work can be performed.
