Definitions
- the invention relates to a method for producing friction linings from binder-bound pressed material, in particular brake or clutch linings, wherein
- the material to be pressed is filled into a mold or receptacle
- the material to be pressed is pressed with at least one stamp-like pressing tool
- the invention further relates to a device for the production of friction linings from binder-bound pressed material, in particular brake or clutch linings
- a stamp-like pressing tool that can be moved into and out of the mold and compresses the material to be pressed
- a counter pressure plate as an abutment for the pressing force exerted by the pressing tool.
- reaction gases are formed when the binders are crosslinked. Since the material to be pressed, which is generally in the form of bulk material, is compressed, the air which has been compressed and heated in the mold must be removed from the friction lining. In the compression of the material to be pressed, which usually takes place under pressure and temperature, other components can also produce steam or further reaction gases, for example ammonia. These gases must also be removed from the friction lining. So far, this has generally been done between the individual pressing processes, since the gases are discharged for the course of binder reactions and for the production of a homogeneous a friction lining is necessary.
- the procedure is such that the pressing tool, ie the ram, is opened against the pressing movement and closed again after the friction lining has been degassed. If pressure and heat are applied again, further gases may be generated, which must also be removed. The degassing stroke of the ram is repeated. This is two-time. Long total press times are the result. In addition, the reactions in the material to be pressed can only occur at intervals when it is pressed into the friction lining. Under certain circumstances, this leads to incomplete hardening of the friction lining and to inhomogeneities in the friction lining.
- the known type of degassing has another disadvantage.
- the hot, smooth surface of the press ram often makes the surface of the friction lining "glass-like" smooth and thus poorly permeable to gas diffusion.
- the gases have to diffuse out of the friction lining against the pressing direction - i.e. over the smooth surface. As I said, this is not easily possible. Due to the low inherent strength of the friction lining at the time of degassing, the internal gas pressure can lead to cracks, bubbles and delamination. A friction lining with such errors is unusable.
- the method mentioned at the outset is characterized in that the gaseous or vaporous media to be discharged are discharged radially and / or via the pressing tool side of the friction lining during and / or after the pressing process, the pressure tool exerted on the friction lining Press pressure is maintained at least at a reduced level.
- the invention combines several advantages. On the one hand, the pressing times can be kept to a minimum. There is no need for air cycles - that is, no removal and retraction of the press tool into the mold. Instead, the degassing can take place continuously. Through the action of the press tool (ie through pressure and heat) during the entire press process, the friction lining can harden homogeneously. In particular, the reactions taking place at elevated temperature in the pressed material run completely and within a very short time. The hardening process is favored by the fact that the surfaces of the covering are in constant contact with the heated tool. A separate hardening can therefore be omitted.
- Another advantage is the high quality of the friction linings produced.
- the internal gas pressure cannot - unlike in the prior art - destroy the coating. There is considerably less waste.
- the clamping force and / or the clamping path the compressibility of the friction lining can also be specifically adjusted.
- the friction lining can outgas over its entire radial area.
- the invention is based on the knowledge that, in a direction perpendicular to the pressing direction, the friction lining has the lowest diffusion resistance for the enclosed gases due to the structure produced during the pressing process. boasted. Cracks, blisters, delaminations etc. in the surface areas of the friction lining are significantly reduced.
- a gap is created between the friction lining and an associated complementary lateral mold wall in the mold, in which the gaseous or vaporous media enclosed in the material to be pressed diffuse out and are subsequently removed .
- its side wall can also be completely exposed radially, as is preferably proposed.
- the pressure and, if applicable, the introduction of heat via the end face of the friction lining are maintained at least at a reduced level.
- the invention is suitable for friction linings of all kinds. In particular, however, it is directed to brake linings or clutch linings. Brake pads for drum brakes can be manufactured according to the invention as well as disc brake pads.
- the friction material connects to the carrier plate, and either through an adhesive layer or through the adhesive properties of the pressed material.
- the carrier plate is pressurized via a counterpressure plate counteracting the pressing tool, and the gaseous or vaporous media are discharged between the carrier plate and the counterpressure plate to the ambient atmosphere.
- a channel can be provided in the counterpressure plate or in the carrier plate (or in both). The channel creates a connection between the openings in the carrier plate and the surrounding atmosphere. Since the channel or channels only occupy a very small surface in contrast to the entire effective area, they are completely uncritical both for the contact area of the counterpressure plate and for the carrier plate.
- the gaseous or vaporous media can also be discharged through the counter pressure plate to the atmosphere.
- the openings in the counterpressure plate are preferably aligned with the openings formed in the carrier plate.
- the device mentioned at the outset is characterized according to the invention in that a radial circumferential wall is provided for the lateral shaping of the friction lining, which is displaceable relative to the press ram and the counter-pressure plate or vice versa.
- the peripheral wall can be "shut down" after a short shaping phase of the friction lining, the sides of the friction lining then being released for degassing.
- a gap is created in which gases or vapors diffuse out. The gap can be enlarged so that the side surfaces of the
- the friction lining is completely exposed.
- a device mentioned at the beginning in which at least one opening is assigned to the side of the friction lining facing the counterpressure plate, which creates a connection of at least a partial area of the friction lining surface with the ambient atmosphere.
- channel-like depressions are formed in the side of the counterpressure plate facing the friction lining, which connect laterally at least a partial area of the friction lining to the ambient atmosphere.
- the channel-like depressions can be designed, for example, as grooves via which the friction lining degasses.
- a carrier plate is arranged between the counterpressure plate and the material to be pressed, which is supported on one side against the counterpressure plate and which is subjected to the material to be pressed from the other side, the carrier plate and the material to be pressed forming the friction lining.
- the friction lining can be degassed radially in the manner described.
- the carrier plate has at least one carrier plate opening through which the gaseous or vaporous media are discharged.
- the carrier plate openings expediently have a funnel-shaped shape which can be produced by a simple stamping process.
- the counterpressure plate can be provided with projections, which preferably partially engage in the carrier plate openings, with a remaining gap remaining through which the gases can escape.
- the counter pressure plate has at least one through opening which connects at least a partial area of the friction lining to the ambient atmosphere.
- the gases are so through the counter pressure plate through to the ambient atmosphere.
- the through openings are advantageously aligned with the carrier plate openings.
- An insert - a so-called plug stamp - can be inserted into the through opening in the counterpressure plate.
- An annular gap remains between the plug punch and the through opening.
- the counter pressure plate is provided on its side facing away from the friction lining with a groove which leads the gases from the annular gap to the outside.
- the annular gap is set so that no material to be pressed or friction material can escape into the gap between the plug die and the counterpressure plate.
- the plug stamp is therefore simply removed if it shows signs of wear and replaced with a new plug stamp.
- FIG. 1 and 2 show a schematic sectional view through a first exemplary embodiment of a device according to the invention in the fully closed press end position and a subsequent degassing position, in which the gases enclosed in the friction lining can radially diffuse out;
- FIG. 3 shows a second exemplary embodiment of a pressing device according to the invention, in which the gases and / or vapors are discharged via the counterpressure plate; 4 shows a third embodiment, modified in comparison with the embodiment according to FIG. 3, in which the gases or vapors are removed from the friction lining via channels in the rear of the carrier plate;
- Fig. 5 is a schematic perspective sectional view through a fourth embodiment in which the discharge the gases or vapors occur through the counter pressure plate;
- Fig. 6 is a side view of a plug stamp, as used in Figure 5 in the pressure plate, but on an enlarged scale.
- FIG. 1 a pressing device for the production of brake pads for disc brakes of motor vehicles is shown.
- the press device has a press ram 1 which is movable relative to a peripheral wall 2.
- the peripheral wall 2 is held stationary. Together with the plunger 1, it forms a receptacle or shape for the material 3 to be pressed in the initial state, which forms the friction lining after compression by the plunger.
- a carrier plate 4 made of metal rests on the peripheral wall 2. When the material to be pressed 3 is pressed, the material to be pressed is adhered to the carrier plate 4. The counter pressure of the stamp 1 during the pressing is applied via a counter pressure plate 5.
- a brake pad is produced as follows: First, the stamp 1 is in a lowered position
- the shape formed by the press ram 1 and the peripheral wall 2 is open at the top.
- a defined amount of material to be pressed 3 is filled into the mold.
- the carrier plate 4 is placed on the peripheral wall 2 and biased by the counter-pressure plate 5.
- the press ram 1 now presses the material to be pressed 3 and against the carrier plate 4.
- the material to be pressed can already be compressed to, for example, 1/5 of its volume.
- Openings 6 are formed in the carrier plate 4, into which the material to be pressed can at least slightly enter during pressing and thus additionally create a mechanical anchoring.
- the openings 6 are usually punched and therefore slightly conical.
- the openings 6 are not mandatory. They form a positive connection between the friction lining and the carrier plate 4 (and in particular special high resistance to shear forces), but the positive connection between the friction lining and the carrier plate is sufficient for a reliable connection.
- FIG. 2 shows how the peripheral conversion 2 is opened in the downward direction for degassing. This can take place after a short shaping phase of the friction lining, in which the friction lining receives sufficient stability, even without maintaining the shape of the peripheral wall 2.
- a gap 7 is formed. The gaseous or vapor-like media can diffuse out into the gap 7 and are led out of the mold.
- the shape is shown only partially open.
- the entire side wall of the friction lining can also be exposed, either by lowering the peripheral wall, as shown, or by simultaneously raising the ram 1 together with the counter-pressure plate 5 and the brake lining held in between.
- the pressure of the ram 1 is maintained at least at a reduced level throughout the venting.
- the heat can also be introduced continuously.
- the result is a homogeneous brake pad of excellent quality that can be produced in the shortest possible time. If, for some reason, the material to be pressed 3 is not yet fully solidified - that is to say dimensionally stable - then the peripheral wall 2 can also be raised again after closing it, with the mold closed, in order to stabilize the radial shape of the covering. When the friction lining has completely solidified and the undesired gaseous components have diffused out, the finished brake lining can be removed from the mold.
- FIG. 3 corresponds to the basic structure of the press mold shown in FIGS. 1 and 2, so that only the modifications made are described below in order to avoid unnecessary repetitions, while otherwise referring to the preceding description of FIGS. 1 and 2 can be referred.
- the same reference numerals are assigned to the functionally matching components in the drawing figures.
- the resulting friction lining is to be degassed continuously during the pressing process via the through openings 6 in the carrier plate 4.
- 5 channel-like depressions 8 are machined into the pressure surface of the counter-pressure plate lying on the carrier plate 4. The latter are led from the area of the counter-pressure plate 5 close to the through openings 6 to the outside atmosphere.
- the counter-pressure plate 5 has in its areas opposite the through openings 6 of the carrier plate in each case a frustoconical projection which engages in the through opening 6 during the pressing process.
- the projections have a smaller cross section than the through openings 6, so that they do not completely close the through openings 6. This allows the gases and vapors to diffuse out.
- a lead is not essential.
- FIG. 4 shows an embodiment in which channel-like depressions 8 ′ are laid in the flat side of the carrier plate 4 facing the counter-pressure plate 5. Otherwise, this exemplary embodiment corresponds completely to the exemplary embodiment described above, ie the The gaseous or vaporous inclusions in the molding compound take place continuously during the pressing process via the through openings 6 and the channel-like depressions 8 1 which run from the through openings 6 to the edge of the respective carrier plate 4.
- FIG. 5 illustrates a further possibility for the discharge of gaseous or vaporous media.
- the mold is shown closed.
- a plug punch 9 is inserted into the pressure plate 5 and is essentially aligned with the through opening 6 in the carrier plate 4.
- the stopper stamp 9, together with the counterpressure plate 5, forms an essentially flat plane on its underside, a first annular space 10 remaining between the stopper stamp and the counterpressure plate. Media which diffuse out can enter these, and are discharged through longitudinal grooves 11 formed in the plugging die 9 into a second annular space 12 and from there into a lateral discharge duct 13 to the ambient atmosphere.
- the second annular space 12 is particularly necessary when a component of the pressing device acts on the counterpressure plate 5, which component lies flat on the counterpressure plate in the area of the plug die 9. Through the annular space 12 and the channel 13, the gases are derived "below" the top of the pressure plate 5.
- the plug stamp 9 is subject to a certain amount of wear. In addition, it can be used to identify the brake lining by embossing the underside of the base plate by embossing the friction material entering the carrier plate opening 6. Such labeling can e.g. contain the quality of the friction material or it meets other customer-specific requirements.
- the plug stamp 9 is shown on an enlarged scale in isolation.
- the illustrated plunger stamp 9 has four grooves 11. It goes without saying a groove 11 is already sufficient, it should be noted that the pressed material 3 can enter the first annular space 10 between the plug die 9 and the counter-pressure plate 5 and possibly only closes the groove 11. Several grooves 11 are therefore recommended for more reliable and more uniform discharge of the gases.
- the tamping stamp 9 On its upper side, the tamping stamp 9 has a circumferential shoulder 14 with which it rests on a shoulder 15 of the counter-pressure plate 5 (FIG. 5).
- the plunger stamp 9 On its underside, the plunger stamp 9 has a projection 16 in which, for example, an embossing for typing the brake lining can be introduced.
- a radial release of the brake pad can be done not only by lowering the peripheral wall 2, but - as already mentioned - also by "moving out” the pad clamped between the press ram 1 and the counter pressure plate 5.
- the pressing device is also not limited to the orientation shown in the figures. Filling of the pressed material 3 from above onto a counter-pressure plate 5 or carrier plate 4 already resting on the peripheral wall 2 is also conceivable.
