Abstract

La presente se refiere a un mandril de forja para el forjado en caliente de piezas a trabajar metálicas de forma tubular, compuesto por un cuerpo de mandril y una barra de mandril en el cual el cuerpo de mandril está formado por un material resistente al calor. Para ello el mandril de forja de acuerdo con la presente está conformado de modo que el cuerpo de mandril (1) está provisto en el sector de trabajo de por lo menos una capa (5) de adherencia firme sobre el cuerpo de mandril (1) que reduce la disipacion de calor durante el forjado en el cuerpo de mandril, en donde la capa (5) presenta una conductividad térmica menor que el material del cuerpo de mandril (1) y por lo menos un espesor de 50 micrometros.This refers to a forging mandrel for hot forging of metal work pieces in a tubular shape, consisting of a mandrel body and a mandrel bar in which the mandrel body is formed of a heat resistant material. For this, the forging mandrel according to the present is shaped so that the mandrel body (1) is provided in the work area with at least one layer (5) of firm adhesion on the mandrel body (1) which reduces heat dissipation during forging in the mandrel body, where the layer (5) has a thermal conductivity less than the material of the mandrel body (1) and at least a thickness of 50 micrometers.
