である。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a single-action link press in which a slide is driven by a link mechanism.
従来のこの種のリンクプレスでは冷温間加工工
程のストローク、速度が加工条件に叶つていて
も、上昇工程の所要時間を短かくすることが困難
であつた。 In conventional link presses of this type, it has been difficult to shorten the time required for the ascending process even if the stroke and speed of the cold working process meet the working conditions.

供しようとするものである。 The present invention has been developed in consideration of the above-mentioned problems, and has a long descending range of the slide, and a short and sudden return to the rising end of the slide.This invention reduces the impact force during the machining process and allows the slide to move downward. The purpose of the present invention is to provide a single-action link press that can shorten the time required for one cycle.
以下その構成を図面に示した実施例に基づいて
説明する。 The configuration will be explained below based on the embodiment shown in the drawings.

スライドが連結してある。上記構成を単純化して
示すと第３図に示すようになる。 In the figure, 1 is a first driven shaft having a gear that is rotationally driven by a main pinion 2, and O 1 is its rotation center. 3 is the first driven shaft 1 having this gear
A second driven shaft is provided at a position eccentric to the rotation center O1 of the second driven shaft 3, and the tip of the lever 4 with a radius r2 provided on the second driven shaft 3 and the first driven shaft 1 having the above-mentioned gear.
The position of the radius r 1 from the axis O 1 of is connected by a link 5. 6 is the rotation center O 2 of the second driven shaft 3
With the third driven shaft located at an even more eccentric position,
The tip of a lever 7 with a radius r 3 provided on the third driven shaft 6 and a lever 8 provided with a radius r 2 from the axis O 2 of the second driven shaft 3 are connected by a link 9. . An eccentric drum 10 is provided on this third driven shaft 6, and the base of a connecting rod 11 is fitted into this. A slide (not shown) is connected to the tip of the cooking rod 11. The above configuration is shown in FIG. 3 in a simplified manner.
上記構成において、歯車を有する第１従動軸１
がメインピニオン２より等速回転すると、第２従
動軸３は不等速回転をなす。さらにこの第２従動
軸３により回転される第３従動軸６は上記不等速
回転が増幅されて第２従動軸３より大きな不等速
回転がなされる。 In the above configuration, the first driven shaft 1 having a gear
When the main pinion 2 rotates at a constant speed, the second driven shaft 3 rotates at an inconstant speed. Furthermore, the third driven shaft 6 rotated by the second driven shaft 3 has the above-mentioned non-uniform speed rotation amplified, so that the third driven shaft 6 rotates at a greater non-uniform speed than the second driven shaft 3.
しかして上記第３従動軸６とコンロツド１１と
の関係を、第３従動軸６の低速回転角度域をコン
ロツド１１の下動域に、高速回転角度域をコンロ
ツド１１の上動域にすることにより、スライドの
下降域が長くなり、かつスライドの上降域が短か

る衝撃力を小さくできると共に、スライドの１サ
イクルに要する時間を短縮することができる。 Therefore, the relationship between the third driven shaft 6 and the connecting rod 11 can be changed by making the low speed rotation angle range of the third driven shaft 6 the lower moving range of the connecting rod 11 and the high speed rotation angle range making the upper moving range of the connecting rod 11. The descending region of the slide is long, and the ascending and descending region of the slide is short, so that it can be returned quickly, and the impact force in the processing process can be reduced, and the time required for one cycle of the slide can be shortened.
