    • The invention relates to a machining device comprising a framework, a transmission shaft (3) and a drive mechanism (1) comprising a rotation member (13) for driving said shaft in rotation about its axis (A), a drive member (18) in helical connection with the shaft to drive the translation thereof along its axis with a feed movement, according to the relative rotational speed of said rotation and drive members. The drive member is mounted with the ability to effect translational movement with respect to said framework along the axis (A) and is positioned between said rotation member and an end for coupling of said shaft to a cutting tool, while an electromechanical actuator (20) is mounted in a fixed frame of reference associated with said framework in front of said drive member (18) to which it can be coupled in order to cause it to oscillate translationally so as to superpose an axial oscillation component with said feed movement.
    • 本发明涉及包括框架,传动轴(3)和驱动机构(1)的机械加工装置,驱动机构(18)包括用于驱动所述轴围绕其轴线(A)旋转的旋转构件(13) 根据所述旋转构件和驱动构件的相对旋转速度,与所述轴螺旋连接以通过进给运动沿着其轴线驱动其平移。 驱动构件安装为能够实现沿着轴线(A)相对于所述框架的平移运动,并且定位在所述旋转构件和用于将所述轴联接到切割工具的端部之间,而机电致动器(20) 安装在与所述框架相关的固定参考系中,所述固定参考系在所述驱动构件(18)的前部可以与其耦合,以便使其平移振荡,从而通过所述进给运动叠加轴向振动分量。

    • The invention concerns a method and a facility for progressively transforming a strip of metal material (25). Said method comprises the following steps: Providing a progressive die (12) comprising a plurality of workstations (14, 16, 18, 20, 22, 24); providing a longitudinal strip (25) of a metal material having a series of strip portions (48, 50, 52, 54, 56, 58, 60, 62); and driving said strip (25) through said progressive die (12), at a predefined pitch, while actuating said progressive die (12) at each pitch such that said plurality of workstations (14, 16, 18, 20, 22, 24) simultaneously transforms a plurality of strip portions, Providing heat energy to said strip of metal material (25), upstream from at least one of said workstations of said plurality of workstations (14, 16, 18, 20, 22, 24).
    • 本发明涉及用于逐渐变换金属材料条(25)的方法和设备。 所述方法包括以下步骤:提供包括多个工作站(14,16,18,20,22,24)的渐进式模具(12); 提供具有一系列带状部分(48,50,52,54,56,58,60,62)的金属材料的纵向条(25); 并以预定间距以所述间距驱动所述条带(25)穿过所述渐进式模具(12),同时以每个间距致动所述渐进式模具(12),使得所述多个工作站(14,16,18,20,22,24) 同时转换多个条带部分,在所述多个工作站(14,16,18,20,22,24)的所述工作站中的至少一个的上游向所述金属材料条(25)提供热能。
