Definitions
- the invention relates to a head brush with a variety of Grinding bristle bundles, which are used as fill material with one End are held in a base plate and with their other Form the end surface of the head brush, the trimming surface is profiled and the profiling of the trimming surface deviates from a steady, straight line.
- Such a head brush is e.g. B. from EP-A-0 924 031, State of the art according to Art. 54 (3) EPC, known.
- Head brushes as such are well known. It did Deburring car rims and especially aluminum rims in in the past carried out manually with files. The deburring was necessary to the after the casting process of the aluminum rims to remove stuck burrs. Were used also cup-shaped grinding tools with abrasive cloth flaps. However, these attempts showed no useful results.
- pot brushes which are on wooden or plastic base plates were attached. These pot brushes pointed grinding bristles as fill material. However these cup brushes also meet the high requirements of the rim manufacturers not fair.
- the aim of the invention is the head brush mentioned at the beginning so that they can be used to deburr pot-shaped Objects and especially when deburring Aluminum rims shows optimal work results and this from machining the first rim.
- Another object of the invention is an improved deburring device to be specified for the deburring of car rims.
- That arranged on the outer edge of the base plate grinding bristle bundle arranged radially outwards and / or on the inner edge Grinding bristle bundles are inclined radially inwards.
- the inclination the grinding bristle bundle can be between about 5 ° and about 45 ° in relation to an orthogonal protruding from the base plate level Axis.
- the tilt also serves to juxtapose arranged grinding bristle bundle through their Support each other's touch.
- the profiling of the facing surface preferably is selected such that the outer edge of the head brush is rounded Profile with the radius R.
- some of the grinding bristle bundles are with a smaller diameter than the rest Provide abrasive bristle bundle.
- the bristles at least some bundles of grinding bristles of different lengths be designed.
- the head brush according to the invention is characterized in that for every application zone when deburring aluminum rims the equipment of the head brush is adapted. This is through the slope of some of the loop bristle bundles and the one mentioned Profiling of the trim surface and through the support the grinding bristles reached against each other and if necessary through the mentioned flexible buildable synthetic resin foundation supports the base plate for the bristle attachment. additionally can be done by differentiating the length of the grinding bristles optimally the contact pressure required for deburring the requirements are adjusted.
- the deburring device for car rims is characterized by this from that the head brush according to the invention and a Drive device is provided, through which the head brush Can be rotated into the cup-shaped opening of the car rim is.
- the car rim is preferably an aluminum rim.
- the head brush according to the invention are proportionate short machining times for deburring Aluminum rims possible.
- a good price-performance ratio achieved with uniform product quality, so that the use of such a deburring device for the rim manufacturer compared to the previous manual Deburring measures are expedient and sensible.
- the exemplary embodiment of a head brush 1 is shown in FIG presented the invention.
- the head brush 1 has a round one Base plate 2 on.
- This base plate 2 has at its top Area over a plurality of circular openings 20, in the grinding bristle bundles 10, 11 of different diameters are used.
- the grinding bristle bundles 10, 11 form that Trim material 3 of the head brush 1 and are in the present Example arranged in a ring.
- the grinding bristle bundles 10, 11 have different Diameter, the individual grinding bristles 10 des others can be of different lengths.
- the profiled head brush 1 is essential Design of the trim surface 4.
- the trim surface 4 is namely what can be clearly seen in particular from Figure 2 is, with a radius R and thus with a rounding on Provide the outer edge of the head brush 1.
- the radius R is expedient optimally to the inner radius of the machined Car rim adjusted.
- This radius R of the head brush 1 can for example the same or approximately the same radius have like the car rim on its cup-shaped inner contour, to be deburred.
- the facing surface 4 is shown by the outer radius R, the invention is not limited to this. Rather lies a profiling by a straight line L or straight The level of the facing surface 4 deviates within the scope of the invention. So the head brush 1 z. B. also an excessive on the inner edge Have length.
- the Standing edge bristle bundle 10 inclined so that the diameter of the trim material 3 from the surface the base plate 2 in the direction of the facing surface 4 somewhat extended until the radius R begins.
- the one on the outer edge of the head brush 1 located grinding bristle bundle 10 thus protrude Outside. This can be done in a degree of inclination of about 5 ° to 30 ° Case.
- the Base plate 2 On the side opposite the trim material 3 is the Base plate 2 with a fastening device 21, here one Opening. A connecting part can be inserted into this opening be clamped or screwed in, which with a drive shaft a drive device of a deburring machine communicates. With rotating drive device the head brush is then rotated so that a Deburring the car rim is possible when using the head brush rotatingly inserted into the cup-shaped opening of the car rim and being moved back and forth there.
- Filaments with a carrier material can be used as grinding bristles as polyamide, in particular polyamide 6 and polyamide 612 become.
- This carrier material preferably has one Aluminum oxide or silicon carbide abrasive grain on in a share of predominantly 30% in grain sizes 46 to 500. It is more appropriate for deburring aluminum rims Use alumina as the grain, as this compares is more resistant to silicon carbide and not as light breaks. Furthermore, it has been found that deburring of aluminum car rims with the use of brushes, which have abrasive bristles with a grain of aluminum oxide, result in smoother surfaces.
- the deburring device can also be used by others Pot-shaped objects suitable as car rims.
