    • In order to obtain better noise protection, longer service life of machine and tools, and to increase the productivity of wire shaping apparatuses, in particular, a universal spring winding machine with a cutting device (16) consisting essentially of a movable cutting tool (38) with drive (80) and a stationary cutting tool (150) at which the endless intaken wire is cut, this invention suggests: to conceive the drive of the cutting tool (38) in the form of a fluid operated cylinder piston aggregate cutting cylinder (80) with program-controllable NC valve (78); to fix the movable cutting tool (38) by means of an adapter (158) to the movable part of the aggregate (piston rod 154); to bring the moving direction of the latter (154) into accordance with the shearing direction of the movable cutting tool (38).
    • 为了获得更好的噪声保护,更长的机器和工具的使用寿命以及提高线材成形设备的生产率,特别是具有主要由可动切割工具(38)组成的切割装置(16)的通用弹簧卷绕机 )具有驱动器(80)和固定切割工具(150),在该固定切割工具(150)处切割环形线,本发明提出:以流体操作的气缸活塞聚集体切割圆筒的形式来设计切割工具(38)的驱动 (80)具有程序可控数控阀(78); 通过适配器(158)将可移动切割工具(38)固定到聚集体(活塞杆154)的可移动部分; 以使后者(154)的移动方向与可动切割工具(38)的剪切方向一致。
