Method and thermoforming apparatus for producing forged steel sheet forming components

Abstract

The invention relates to a method and a thermoforming device for producing forged steel sheet shaped components, the thermoforming device comprising a furnace (8) by means of which the steel sheet to be hot formed is at least partially heated to an austenitizing temperature, the heat The forming device also includes a forging device (10) for hot forming and forging of steel sheets heated in a furnace. In order to realize the utilization of the capacity of the current rolling mill and realize a higher number of strokes and thereby realize a higher production capacity, it can be seen from the present invention that a heating device (7) is arranged in front of the melting furnace (8), and the steel plate (2) is heated by the heating device. ) is at least partially heated to a temperature below the austenitizing temperature, preferably to a temperature in the range of 500°C to 700°C, and the forge (10) is arranged in a multi-stage form, wherein the first part (10.1) of the forge has at least A first tool for hot forming and cooling of the steel sheet heated in the furnace (8), while the next part (10.2) of the forging plant (10) has at least one second tool for further cooling of the hot formed steel sheet and wherein the second tool further forms, shears and / or perforates the hot-formed steel sheet.

Description

technical field [0001] The invention relates to a thermoforming device for producing forged steel sheet shaped components, comprising a furnace by which the steel sheet to be thermoformed is at least partially heated to an austenitizing temperature, the thermoforming device of the invention also comprising Forging unit for hot forming and forging of steel plates heated in a furnace. The invention also relates to a method for producing forged steel sheet shaped components, in which the steel sheet is at least partially heated to an austenitizing temperature in a furnace, then hot-formed by a forging device and cooled by a refrigeration device. Background technique [0002] The forging of high-strength body parts is usually performed in a dedicated thermoforming unit, which generally consists of a furnace unit and a rolling press, and in some cases a multi-stretch rolling press. Typically, the calenders are hydraulic calenders because of the relatively long closing times that...
