Abstract
Un procedimiento para el forjado en caliente de perfiles de metal con simetría axial y angulosos en la sección exterior (1, 1a, 1b, 1c, 1d), en particular de acero, mediante una máquina de forjado radial en el que se conforma un cuerpo macizo o hueco colocado a temperatura de forjado como material de partida, mediante martillos de forjado (2a a 2e) actuantes en la cara exterior del material de partida, dispuestos en forma simétrica en torno al eje medio longitudinal del material de partida y accionados de modo radial para producir un perfil anguloso y con simetría axial (1, 1a, 1b, 1c, 1d) con un ángulo de simetría axial (Aₐˣⁱₐₗ), en donde el material de partida en las fases sin contacto con la pieza de forja de las carreras de los martillos de forjado (2a a 2e) se rota mediante al menos un manipulador un ángulo de rotación (Aʳₒₜ) controlado por máquina que se ubica entre un ángulo mínimo de rotación (Aₘíₙ) y un ángulo máximo de rotación (Aₘáˣ). A fin de mostrar un procedimiento mejorado, se propone que, para el caso en que el ángulo de simetría axial (Aₐˣⁱₐₗ) es mayor que el ángulo de rotación máximo controlado por máquina (Aₘáˣ), se accionen los martillos de forjado (2a a 2e) en períodos de forjado con al menos una carrera en vacío y una carrera de trabajo, el material de partida se rote por carrera en un período de forjado un ángulo de rotación (Aʳₒₜ), en donde la cantidad de rotaciones (Nʳₒₜ) en torno al ángulo de rotación (Aʳₒₜ) corresponde a un cociente entre el ángulo de simetría axial (Aₐˣⁱₐₗ) y el ángulo de rotación máximo controlado por máquina (Aₘáˣ), redondeado hacia arriba hasta el número entero próximo superior o, para el caso en que el ángulo de simetría axial (Aₐˣⁱₐₗ) es menor que el ángulo de rotación mínimo controlado por máquina (Aₘíₙ), el material de partida sea conformado por al menos una parte de los martillos de forjado (2a a 2e) con superficies de forjado para al menos dos contornos de simetría adyacentes, la cantidad (M) de contornos de simetría por martillo de forjado (2a a 2e) corresponda al cociente entre el ángulo de rotación mínimo controlado por máquina (Aₘíₙ) y el ángulo de simetría axial (Aₐˣⁱₐₗ), redondeado hacia arriba hasta el número entero inmediato superior, se accionen los martillos de forjado (2a a 2e) en períodos de forjado con solo una carrera de trabajo y por cada carrera se haga girar la pieza de forja dentro de un período de forjado entorno al ángulo de rotación (Aʳₒₜ).A process for hot forging of metal profiles with axial and angular symmetry in the outer section (1, 1a, 1b, 1c, 1d), in particular of steel, by means of a radial forging machine in which a body is formed solid or hollow placed at floor temperature as a starting material, by means of floor hammers (2a to 2e) acting on the outer face of the starting material, arranged symmetrically around the longitudinal median axis of the starting material and operated in a manner radial to produce an angular profile with axial symmetry (1, 1a, 1b, 1c, 1d) with an axial symmetry angle (Aₐˣⁱₐₗ), where the starting material in the phases without contact with the racing forge of the forging hammers (2a to 2e) a machine controlled rotation angle (Aʳₒₜ) is rotated by at least one manipulator that is located between a minimum rotation angle (Aₘíₙ) and a maximum rotation angle (Aₘáˣ). In order to show an improved procedure, it is proposed that, in the case where the axial symmetry angle (Aₐˣⁱₐₗ) is greater than the maximum machine controlled rotation angle (Aₘáˣ), the slab hammers (2a to 2e) ) in periods of forging with at least one empty run and one working stroke, the starting material is rotated per stroke in a period of forged a rotation angle (Aʳₒₜ), where the amount of rotations (Nʳₒₜ) around to the angle of rotation (Aʳₒₜ) corresponds to a quotient between the angle of axial symmetry (Aₐˣⁱₐₗ) and the maximum angle of rotation controlled by machine (Aₘáˣ), rounded up to the next near whole number or, for the case in which the axial symmetry angle (Aₐˣⁱₐₗ) is less than the minimum machine-controlled angle of rotation (Aₘíₙ), the starting material is made up of at least a part of the slab hammers (2a to 2e) with forged surfaces for at least two adjacent symmetry contours, the amount (M) of symmetry contours per slab hammer (2a to 2e) corresponds to the ratio between the minimum machine-controlled rotation angle (Aₘíₙ) and the axial symmetry angle (Aₐˣⁱₐₗ), rounded up to the immediate upper integer, the slab hammers (2a to 2e) are activated during wrought periods with only one work stroke and for each stroke the workpiece is rotated forging within a period of forging around the angle of rotation (Aʳₒₜ).
