Abstract: AN APPARATUS FOR PRODUCING ONE-PIECE LINKS IN ONLY TWO STATIONS. THE FIRST OF THESE STATIONS CONTAINS A MECHANISM FOR SEVERING A PIN OF A PREDETERMINED LENGTH FROM A ROD OR WIRE BY MEANS OF TWO NOTCHING BLADES WHICH RECIPROCATE IN OPPOSITE DIRECTIONS TO EACH OTHER WITHIN THE SAME PLANE EXTENDING TRANSVERSE TO THE AXIS OF THE ROD. THE FIRST STATION FURTHER CONTAINS A PRESS CLOSELY ADJACENT TO AND PRECEDING THE SEVERING MECHANISM FOR CLAMPING THE ROD IN A FIXED POSITION DURING THE SEVERING OPERATION AND FOR BENDING AT THE SAME TIME THE CENTRAL PART OF THE PIN BEFORE BEING SEVERED TO PROVIDE THE LINK WHEN SUBSEQUENTLY BENT WITH A CURVED BACK. THE SECOND STATION CONTAINS A SINGLE BENDING UNIT IN WHICH THE PREVIOUSLY SEVERED PIN IS BENT WITH A CURVED BACK. THE ACTION TO ITS FINAL SHAPE BY TWO BENDING ROLLERS WHICH ROLL THE PIN ABOUT A BENDING MANDREL AND ARE CONNECTED TO GUIDE ROLLERS WHICH ROLL ALONG GUIDEWAYS SO THAT THE BENDING ROLLERS THEMSELVES ARE INDIRECTLY GUIDED AND ONLY HAVE TO ENGAGE WITH THE PIN DURING THE BENDING OPERATION. AFTER A PIN HAS BEEN SEVERED IN THE FIRST STATION, IT IS PASSED BY CONVEYING TONGS FROM THIS STATION TO THE BENDING UNIT AND INTO THE PROPER POSITION THEREIN FOR THE BENDING OPERATION.

Abstract: The production of pins which subsequently are to be bent and welded to form chain links, in which each pin is cut off a rod by a pair of equal wedge-shaped blades which are simultaneously reciprocated in opposite directions to each other within a common central plane extending transverse to the axis of the rod, and which while cutting impress V-shaped notches into diametrically opposite sides of the rod so that the ends of each pin have an angular shape similar to a peaked roof. One preferred embodiment of the invention provides that, instead of forcing the two blades so deeply in the material that their cutting edges engage with each other and thus cut off each pin completely, the blades are impressed only for such a distance into the material that a thin connecting web-remains between the pin and the rod supply which web is then shorn off by moving the pin transversely relative to the rod.

Abstract translation: 销的生产随后被弯曲和焊接以形成链节，其中每个销通过一对相等的楔形刀片切断杆，所述一对相等的楔形刀片在公共中心平面内彼此相反的方向同时往复运动 横向于杆的轴线延伸，并且在切割时将V形凹口注入到杆的径向相对的两侧，使得每个销的端部具有类似于顶峰的角形。 本发明的一个优选实施例提供的是，不是迫使两个叶片在切割刃彼此接合的材料中如此深入，并且因此完全切断每个销，所以叶片仅施加到材料的这样的距离上 薄的连接腹板保持在销和杆供应之间，然后通过相对于杆横向地移动销而将腹板松开。
