Definitions
- the invention relates to a cold rolling machine according to the preamble of claim 1, in particular Roll bar suitable for such cold rolling machines and a method for cold rolling a workpiece.
- this Workpiece clamping device In such cold rolling machines to be processed Workpiece rotatable between two tips or other Tensioning clamped, this Workpiece clamping device usually a feed axis assigned.
- the desired profiling of the workpiece takes place via two synchronously counter-rotating Rolling rods simultaneously on the workpiece impinge and this first by friction and later set in rotation by positive engagement. It will the material in the free spaces of the tool, d. H. of the Rolling rods displaced.
- the height of the ground profile of the rolling rod in the forming area too, so that each tooth of the rolling rod is slightly deeper in the Workpiece is pressed in, as the previous one.
- To Achieving the full tread depth can be a Kallibrierzone and a relaxation zone, along which the geometry and the surface quality of the workpiece is optimized.
- This non-cutting cold forming profiles such as Splines (straight or oblique), Spiral gears, oil grooves, threads or knurls is approx. thirty times faster than the machining the profiles.
- Cold rolled workpieces also offer one higher strength, better surface quality and large Accuracy.
- the invention has the object, a cold rolling machine and to provide a method of cold rolling that minimizes downtime are reduced during production.
- the cold rolling machine with a Delivery device provided with integrated feed drive, about the rolling rods during the rolling process are adjustable in the direction of engagement. That is, everyone Rolling rod is assigned to an infeed axis, which is a Adjustment of the rolling rods in approximately radial direction with Reference to the workpiece to be machined allows.
- This delivery device can thus the tread depth be changed during the rolling process, so that, for example the desired final tread depth not - like required in the prior art - during a Feed movement of the rolling rods, but during several Walzstangenh Claus is formed, where the rolling rods be adjusted in the radial direction. This makes it possible to minimize the length of the rolling rod, so that the dimensions of the cold rolling machine comparatively stay low.
- the rolling rods can substantially executed with consistent tread depth so that their production is much easier than in the conventional rolling rods with in the rolling direction Growing tread depth is.
- the initially described Calibration and relaxation zones can be over small Ramps formed at the end portions of the rolling rods be with the extending between the ramps Range of rolling rods is substantially consistent Profile depth is formed.
- Each of the two rolling rods each have a guide carriage associated, which is displaceable along inclined guides is.
- These two inclined guides are V-shaped employed to each other, so that by moving the Guide carriage along the associated inclined guide the radial distance between roll bar and workpiece is changeable.
- the delivery movement is carried out by Moving the rolling rod along the wedge-shaped Angular guides, so that by adjusting the Rolling rods without tool change a variation of Number of teeth, the rolling of even and odd numbers of teeth, a positioned rolling and the quality optimization of the profile by division correction is possible.
- each guide carriage has its own feed drive, For example, associated with a planetary spindle drive is.
- suitable Drives such as rack drives, ball screw drives or hydraulic drives used become.
