Problems solved by technology

Due to the design of the heating means used, the temperature measurement due to the design and the inertia of the entire system with regard to the required temperature control, it is not possible, for example, to ensure a constant temperature on the face of the punch plate or the punch
[0012] Furthermore, the described pressing method and pressing tool do not work energy-efficiently, since the energy provided for heating the friction material is small relative to the total energy consumption, which is ultimately passed to the pressing tool The heating of the steel used in the various components is determined by the

Embodiment Construction

[0024] figure 1 A possible embodiment of an extrusion punch 1 according to the invention is shown, which has a punch foot 2 on which a (metallic not shown here) punch can be provided. A head board or pressing board, an isolation board 3 , a heating board 4 with electrical connections 5 .

[0025] A similar arrangement is possible for mirror panels. The punch foot is replaced here by the (metallic) mirror plate.

[0026] In a further advantageous configuration of the invention, a so-called forming plate can be applied to a separate heating plate of the extrusion punch, which is then brought into direct contact with the extrudate during the extrusion process. The forming plate is then in figure 1 on the surface of the heating plate 4 facing away from the punch foot 2 .

[0027] The forming plate can be connected to the punch foot in a simple manner via a preferably ceramic heating plate. This fixing can be achieved, for example, by inserting a plurality of holes in the heat...

Abstract

The present invention relates to a pressing tool for producing friction linings for motor vehicles, wherein the pressing tool comprises a mould, a punch (1) and a mirror plate, wherein the punch (1) and the mirror plate comprise separate ceramic heating plates (4) which during pressing are in contact with the pressed material, and wherein in addition profiled plates can be mounted on said heating plates (4), which profiled plates, if mounted, are in contact with the pressed material during pressing.

Description

technical field [0001] The present invention relates to an apparatus and method for manufacturing friction and brake linings. Background technique [0002] Brake linings with a carrier plate (friction lining carrier) and a friction lining located thereon are used in various fields, but especially in the motor vehicle industry and here especially in trucks and passenger vehicles and are therefore used in Manufactured in correspondingly large quantities. Various types of carrier plates and friction linings are used here, which differ considerably in their size, shape, thickness and materials used, since almost every vehicle type has different brake linings. [0003] The carrier plate is generally a metal part, a sheet metal part or a cast part. Friction linings are manufactured from granular, fibrous and / or granular formable extrudates. Typical pads contain metals, filler materials, sliding and lubricating media and organic components such as resins, rubbers, organic fibers...
