Embodiment Construction

[0025] figure 1 A longitudinal section through a conventional punching and rolling mill for machining cylindrical workpieces 1 is shown.

[0026] The workpiece 1 is mounted on a workpiece holder 2 which can be advanced along its axis z in the machining area 3 . This feed takes place, for example, via its own drive 4 , which drives the spindle 6 via a transmission 5 .

[0027] A forming tool 9 driven by a drive 8 is mechanically connected directly to the workpiece holder 2 via a transmission 7 of the Malformed gear type. The intermittent rotation of the workpiece holder 2 about the axis z is thus directly coupled or synchronized with the movement of the forming tool 9 according to the transmission ratio and the configuration of the transmission 7 of the Martensitic intermittent transmission type. Due to this configuration, a certain profile can now be produced on the surface of the workpiece 1 by means of the forming tool 9 .

[0028] With this construction, it is now possib...

Abstract

The invention relates to a device for producing cylindrical workpiece having defined profiled sections. The device comprises a workpiece holder that is axially displaceable and intermittently rotates about a longitudinal axis, and shaping tools that periodically act upon the workpiece. The inventive device is characterized by at least one drive for the intermittent rotation of the workpiece holder, which is mechanically separate from the drive for the shaping tools. The drive is linked with an electronic control which controls the intermittent rotational movement depending on the drive of the shaping tools. The invention allows to adjust any intermittent movement relative to the position and angle of the workpiece, thereby contributing to a precise and especially rapid processing of the workpiece.

Description

technical field [0001] The invention relates to a device according to the preamble of claim 1 and a method according to the preamble of claim 7 . Background technique [0002] In order to produce cylindrical workpieces by cold forming, which are to be given a profile with a toothed geometry, stamping mills are conventionally used. Here, the movement of the tool (i.e. the machining movement, orientation and feed of the forming roll or roll) and the movement of the workpiece (i.e. the axial feed of the workpiece relative to the tool and the rotation of the workpiece) must be geometrically matched to each other in order to obtain The corresponding dimensions and precision achieve the desired profile. [0003] As a rule, the machining and feed movements of both the tool and the workpiece can be performed continuously by coupling these movements by means of mechanical or electronic transmissions. However, in order to manufacture a certain straight or helical toothing, the workp...
