Embodiment Construction

[0025] figure 1 A die 10 is shown, which can be used in a press for thermoforming a sheet metal blank of a sheet metal component 17 . The mold 10 comprises a lower mold half 12 u which rests on the base plate 11 . The lower mold half 12u cooperates with the upper mold half 12o. The mutually facing active surfaces of the upper mold half 12o and the lower mold half 12u are designed correspondingly so that they serve as a die and a punch of a stamping tool. exist figure 1 In the example shown, the upper mold half 12o is designed as a punch and the lower mold half 12u is designed as a die. Without departing from the scope of the present invention, the upper mold half and the lower mold half can be exchanged with respect to their arrangement, so that the upper mold half acts as a die and the lower die half acts as a punch. The upper mold half 12o and the lower mold half 12u are movable relative to each other. figure 1 The shown mold halves 12o, 12u can be moved away from each ...

Abstract

The invention relates to a moulding tool (10) for producing hot-formed components (17), in particular moulded sheet metal parts consisting of steel, aluminium, magnesium or a combination thereof, said tool comprising a lower tool part (12u) and an upper tool part (12o) which are displaceable relative to one another and have corresponding active areas for forming the component (17). At least some sections of at least the active area of one tool part (12u, 12o) can be cooled and the moulding tool is provided with at least one pickling device (18, 18).

Description

technical field [0001] The invention relates to a mold for producing thermoformed components. Background technique [0002] In today's automotive industry, the comfort of vehicle occupants is gradually improved through the use of special equipment. These equipments include many electromechanical components like sensors, motors, actuators and serve to simplify the driving task for the driver. However, the weight of the vehicle also increases with the increase in comfort. In order to solve this problem, attempts have been made in the prior art to construct structural components of the vehicle body with reduced weight. [0003] Structural components of the body not only play a decisive role in the stability of the vehicle, but also play a key role in safety in the event of a crash. In order to resolve the conflict of objectives between reducing the component weight of structural components and at the same time maintaining or achieving high mechanical property values, it has ...
