Abstract

The invention discloses a preparation device and process of a semimetal friction plate. The preparation device of the semimetal friction plate is characterized in that a base is fixedly connected with a vertical column; a movable sleeve is arranged on the vertical column; a guide line bracket is arranged on the sleeve; a plurality of circles of guide lines are fixed to the guide line bracket and each one is provided with a disconnecting switch and a resistor; all the guide lines are connected with a main switch. The preparation process of the semimetal friction plate comprises the following steps: positioning a friction plate die provided with a semimetal friction plate mixture on a worktable and keeping 2 to 5mm away from an induction coil; turning on the main switch and a secondary switch; adjusting the resistance and adjusting the current of the inner circle to be 0.5 to 2A; progressively increasing the current by 0.1 to 0.3A each circle from inside to outside; turning off the main switch after 3 to 5 seconds; then drying a friction sheet abrasive tool, performing hot press molding and smoothening. According to the preparation device and process of the semimetal friction plate, the distribution density of metal fibers in the semimetal friction plate is gradually increased from an inner arc to an outer arc according to the electromagnetic induction principle, so as to gradually improve the wear resistance from the inner arc to the outer arc surfaces, and thus the wear uniformity of the whole friction plate can be realized.

Description

technical field [0001] The invention belongs to the technical field of mechanical processing, and in particular relates to a preparation device and a preparation process of a semi-metallic friction plate. Background technique [0002] As we all know, automobile disc brakes are braked by the friction between the friction material on the friction plate and the surface of the brake disc under the action of external force, and the friction material will wear and tear. When the wear reaches a certain level, the friction plate will Thinning, so the friction plate should be replaced regularly, otherwise it will affect the performance of the car. However, since the brake disc of an automobile is disc-shaped, the friction lining is usually made into a fan shape. The outer arc of the fan (with a radius of R) is slightly smaller than the outer diameter of the brake disc, and the inner arc of the fan (with a radius of r) is smaller than the outer diameter of the brake disc. The inner d...
