Definitions
- the invention relates to a brushing device according to the preamble of independent claim 1.
- Such a device is for example the US 5,299,394 refer to.
- Brushing machines for treating technical or decorative surfaces for example for deburring, grinding or fine grinding and polishing are long known in a design as a simple brush holder with manual delivery of Bürstguts.
- various brushing devices have been developed to ensure, on the one hand, a higher degree of automation and, on the other hand, a higher reproducibility of the brushing process.
- CNC-controlled systems from Sinjet Osborn are known which are used for surface modification.
- these systems are used for deburring tools.
- These systems are technically complex and expensive, since here too a CNC control acts on a movable in several axes Bürstarm.
- the delivery of the brush to the surfaces to be machined can be done, for example, by entering the geometric tool dimensions from which the corresponding delivery is calculated. This requires an additional operating effort.
- a much simpler principle is known from a brushing machine of René Gerber AG.
- This machine works in batch mode, loading a turret equipped with radially outwardly directed holders with shank tools and then processing the tools together by means of a revolving disc brush. After completion of the brushing process, the brush disc is lifted and reloaded the revolver.
- a batch operation with corresponding loading and unloading times can be disadvantageous.
- the tools are machined differently over the length of the shaft so that the brushing action on long tools can be much more pronounced at the tip than at the edge portions near the shaft. In addition to the respectively given brush / loading geometry, this is another reason why only machines with a limited length can be machined with such machines.
- a continuous uniform brushing of workpieces with different diameters and lengths should thus be made possible without additional operating effort.
- Such a brushing device is realized by a device according to the features of claim 1, wherein the dependent claims describe different embodiments of the invention.
- the device for processing technical surfaces is particularly suitable for the treatment of substantially cylindrical workpieces.
- At least one processing unit comprises a round or belt brush.
- gas pressure dampers spring means, elastic means or weight-average and, if required, lever means can be used.
- the workpiece carrier may be plate or belt-shaped and provided with a continuously, cyclically or stepwise delivering drive.
- the holders can be rotatable by separate drive means, which comprise, for example, at least one toothed wheel, a ring gear, a friction wheel, a friction ring or the like, or preferably by the tangential forces of the processing unit acting on the circumference of the workpieces.
- a brushing device By such a brushing device is a continuous, gradual and / or cyclical guidance of the rotatable about its own axis workpieces, past the brush stations and a simple assembly and removal of the workpieces to be treated possible without interrupting the brushing process.
- Brush parameters such as time, contact pressure, and rotational speed of the brushes are automatically adapted to different diameters and lengths of the workpieces after the selection of the brushing means, thus ensuring a defined final state of the machined surfaces.
- the individual support satellites can be rotated, for example by rolling on a stationary sprocket, whereby the rotational speed can be varied as known to those skilled in the art.
- Fig.1 shows a belt brushing device.
- the workpieces can be moved without interruption of the circulation or clocked.
- the number and position of the brushes 4 may vary.
- the brush length as known to be adjusted (extension of the roll spacing or distances and / or extension of the belt).
- the modification eg, smoothing, roughening, edge preparation, rounding, deburring
- the tools are 3 in brackets 5, which in turn are mounted on rotatable satellite 2, placed on a and as in Fig.1 and 2 represented plate 1 or a like in Fig. 3 and 4 shown circulating belt 1 'past the brush or brushes 4.
- the holder 5 with the tool 3 rotates about the axis of the satellite 2.
- the direction of rotation and speeds can be varied for plates 1 or band 1 ', satellite 2 or brush 4 if necessary (left and right-handed rotation, different angular velocities).
- the satellite rotation is effected by the force transmitted from the brush 4 to the tools 3.
- the brush 4 can be adapted to the workpiece at an angle, as required, in order, for example, to brush parallel to the flute angle.
- Brushes 4, especially round brushes like in Fig. 2 and Fig. 4 can be arranged overlapping in height.
- one or more brushes 4 may be moved up and down during the treatment, preferably parallel to the tools.
- the brush 4 can be delivered, for example, via a gas spring 6 with a defined pressure with the force of 1-100N to the tool.
- Analogous devices which exert corresponding advancing forces on the brush by spring means, elastic means or weight-average, if necessary with lever reinforcement, are known to the person skilled in the art.
- the compensation to various types varying in diameter and length tools is carried out simply and advantageously purely mechanically, without additional control, since the alignment is done by self-adjustment. If a tool with a larger diameter follows a smaller tool, the brush automatically swivels by the required amount to the side and vice versa, whereby the contact pressure remains the same for both diameters.
- the brush unit 4 including drive motors may be mounted on a pivot arm, not shown here in detail. The pivoting can be to the side or in height.
- the brackets 5 can be made pluggable in a simple manner on the turntable or the tape.
- a clamping or otherwise acting fastening device may further be provided.
- a known clamping spring can be mounted in or on the holder, which holds the tool 3 sufficiently firmly in the holder 5.
- Shank tools and cylindrical components can be processed particularly advantageously with such a brushing device.
- Cylindrical tools without shaft such as hobbing cutters but can be easily edited by means of adapted holder, such as a holder with arbor.
- a brushing device consisting of a plate with 20 holding satellites and three fixed brushes offset by 50 mm in height were used correspondingly Figure 2 , the surfaces of differently coated or uncoated tools with an angle of about 60 degrees from the vertical, or brushed with respect to the tool axis.
- the duration of treatment on a brush at one of the 3 defined heights was set between 5 and 30 seconds, with a particularly good result in terms of surface condition and productivity for a treatment time of 8 to 10 seconds for the selected brush parameters.
- Tools with a functional length between 1 and 150 mm were treated. A 360 degree rotation of the turntable takes in this case about 3 minutes. Since several tools are treated simultaneously, a finished tool can be unloaded at the outlet every 10 seconds and an untreated one can be re-attached.
- two tools per brushing station can be treated simultaneously for brushes of the selected diameter, which means that even with a constant treatment time of 45 seconds, twice the throughput per unit of time can be achieved.
- the edge rounding of tool cutting edges was tested on the various brush bodies equipped with or without abrasives, also with the addition of diamond paste and lubricant.
- the particle size of the diamond particles was 0.25 ⁇ m-15 ⁇ m.
- an edge rounding between 3 ⁇ -30 ⁇ could be set in experiments 1 to 8, ie with very fine grain, the edge can be obtained almost perfectly, while with a slightly coarser grain a defined rounding can be set.
- the edge rounding can be adjusted depending on the tool and application.
- the aim is to stabilize the cutting edge and to achieve equalization of grinding breakages.
- a treatment according to experiment no. 1 with a rotational speed of the plate of 0.3U / min corresponds to about 15 s treatment time per brush or height, proved to be suitable and economical to produce a smoothing without damaging the PVD layer at the cutting edges.
- a multilayer of AICrN and TiSiN single layers (Balinit® Helica) an improvement of the roughness values could be achieved as follows: Roughness values before treatment R a 0.22, R z 4.47, R p 4.07; Roughness values after treatment R a 0.22, R z 2.47, R p 1.72.
- the forces occurring when using a new tool forces can be reduced by 20 to 50%, which significantly improves the running-in behavior of the tools and, for example, the risk of edge breakage and similar undesirable phenomena is reduced during running.
