Thread and lathe rolling device comprising a thread rolling device

摘要

Thread rolling device for generating a thread on a workpiece on a numerically controlled lathe by means of a thread rolling process, - with a fixing support structure (10a, 10b, 10c) for placement of the thread rolling device (1) on the lathe (100), - with a rolling head (12) retained in the fixing support structure (10a, 10b, 10c), which has a hole (13) and carries one or more cuts (12a-12f), which are arranged in the periphery at the edge of the hole (13), and - with a first drive means (14), which is installed to drive the lamination head (12) of rotatable about a first axis of rotation (F1), which extends through the hole (13); wherein the thread rolling device (1) is installed to execute the thread rolling process, wherein: - the workpiece (W) is driven by means of a work spindle (101) of the lathe ( 100) rotatably around the axis of the work spindle (101), while the workpiece (W) extends through the hole (13) of the rolling head (12), - the rolling head (12) It is driven to generate a cutting movement through the first drive means (14) in a rotary manner around the first axis of rotation (F1), and - the workpiece (W) is controlled by means of an installation of control of the lathe in such a way that it moves relative to the rolling head (12) in the direction (Z) of the spindle axis, in which the feed rate of the workpiece (W) is adjusted relative to the head rolling mill (12) in the direction of the spindle axis and the speed of rotation of the work (W) around the spindle axis is adjusted as a function of the thread to be formed, characterized by a second drive means (15), which is installed to drive the rolling head (12) in a rotary manner around a second axis of rotation, extending transversely to the first axis of rotation (F1), for alignment of an angle between the first axis of rotation (F1) and the axis of the spindle, when the thread rolling device (1) is installed in the lathe (100).
