Abstract

The invention provides a hot extrusion mold for producing a profile for electrified high-speed railway feedback line clamps. The mold core of the hot extrusion mold is of a single-cone integral type, and the inner cavity structure of the hot extrusion mold comprises an inlet region, a sizing region, a cone angle transition region and an outlet region, wherein the sizing region is enlarged conically toward the front face of the mold core to form the inlet region; the cone angle transition region is enlarged transitionally between the sizing region and the outlet region; and the cross-sectional shape and size of the sizing region are uniformly enlarged for 0.3-0.8mm on a single side compared with the shape and size of the profile. The hot extrusion mold provided by the invention is suitable for producing a profile copper product with a complex shape, and is especially suitable for producing various special profiles for electrified high-speed railway feedback line clamps, thereby laying a foundation for the subsequent drawing process, realizing continuous volume production of such products, improving production efficiency, reducing cost and shortening production cycle.

Description

Technical field: [0001] The invention relates to a hot-extrusion die for processing copper, in particular to a hot-extrusion die for producing various special-shaped materials for electrified high-speed railway feedback clamps. Background technique: [0002] At present, the products produced in the copper processing industry use relatively simple molds, and the shapes of the processed products are mostly simple and symmetrical shapes such as round bars, squares, and rectangular bars. With the continuous development of the national economy, science and technology, especially with the development of electrified high-speed railways, a large number of copper products with complex shapes have emerged. At first, such products and production technology were imported from abroad, but in order to meet the huge domestic market needs and convenient Foreign technology has been digested and absorbed domestically, and the country has begun to produce complex-shaped electrified high-speed ...
