Embodiment Construction

[0118] The following clearly and completely describes the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only some of the embodiments of the present invention, but not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0119] A carbon slide preparation process, comprising the following steps:

[0120] S1. Extrusion: Extrude the granular material into a carbon strip of a certain size

[0121] (1) Raw materials: 5 parts by weight of flake graphite, 5 parts of carbon black, 60 parts of pitch coke, and 30 parts of pitch are used to prepare raw materials;

[0122] (2) Kneading: put flake graphite, carbon black, and pitch coke in S1 into a kneading pot for dry mixing, stir at a speed of 60 rpm for 40 minutes, and dry mixing temperature 120°C; add pitch...

Abstract

The invention relates to the technical field of carbon slide plate preparation. The invention relates to the technical field of pantograph carbon sliding plate manufacturing, in particular to a carbonsliding plate manufacturing process, a copper pipe groove is pre-embedded in one side of an inner arc of a carbon sliding strip of a pantograph carbon sliding plate, an intact copper pipe air channelis embedded during bonding and curing, and the two ends of a copper pipe are welded to air pipe connectors respectively to form the complete pantograph carbon sliding plate with the airtight safety function. By researching the raw material formula and the process method, the carbon slide strip capable of improving the process quality of a product forming process, a roasting process, an impregnation process and the like and key quality indexes of the product volume density, resistance, breaking strength, compressive strength, uniform structure, impact toughness and the like is prepared. Afterthe pantograph carbon slide plate without the copper pipe air passage is mounted on a pantograph device of an electric locomotive, the carbon slide plate is continuously abraded in continuous operation, the abrasion thickness of the carbon slide strip is continuously reduced, and crack air leakage of the carbon strip possibly occurs under the action of impact force.

Description

technical field [0001] The invention relates to the technical field of carbon slide preparation, and more specifically, relates to a carbon slide preparation process. Background technique [0002] At present, there are three main types of pantograph slides: powder metallurgy slides, pure carbon carbon slides and metal-impregnated carbon slides. Among them, the powder metallurgy sliding plate has high mechanical strength, good impact resistance, good electrical conductivity and wear resistance, but it has serious wear on the catenary wire. The pure carbon-carbon skateboard itself is a very good lubricant, with good self-lubricating performance and anti-friction performance, less wear on the catenary wire, and high temperature resistance, and it is not easy to weld with the catenary wire, but its mechanical strength is low. It has poor impact resistance and therefore breaks or cracks easily. Metal-impregnated carbon slides not only have the characteristics of high mechanical...
