摘要： The invention relates to a roller hearth furnace for heat treating metal sheets and to a corresponding method. The problem of the invention is that of specifying a roller hearth furnace for the alternating processing of AlSi and sheets having zinc alloy coatings for hot working, for which the effort for the changeover is significantly reduced in comparison with the prior art. The roller hearth furnace according to the invention for the heat treatment of coated metal parts is characterised in that it has at least one first zone and one second zone, wherein a temperature below the melting temperature of the AlSi deposits or a temperature of more than approx. 900°C can be maintained in the first zone, while a temperature of more than approx. 870°C can be reached in the second zone.

摘要： The invention relates to a method for producing a shaped and at least regionally hardened sheet metal component, particularly a sheet steel component (15), with at least one perforation (16) produced in it, in which method a preform (13) is heated to forming temperature, subsequently shaped and then at least regionally hardened by corresponding cooling, wherein the at least one perforation (16) in the preform (13) is produced during the course of a punching process before the preform (13) is hardened. According to the invention, the metal piece (14) separated from the preform (13) by punching is fed back to its original position or a corresponding position in the perforation (16), remains there for the duration of the quenching process and is only pressed out during or after removal of the sheet steel component (13) from the die (1), in which it is held during quenching. The invention also describes a quench press die (1) for producing a shaped and at least regionally hardened sheet metal component, particularly a sheet steel component (15), with at least two die parts (2, 3) adjustable against one another for opening and closing the die (1) and with a punching device (7) comprising a punching die (8) for producing a perforation (16) in a preform (13) located between the die parts (2, 3). The die part (2), against which the punching die (8) for producing the perforation (16) works, has a return punch (11), the actuation side of which points towards the punching die (8) and the axis of motion of which corresponds to the axis of motion of the punching die (8), such that a metal piece (14) separated from a preform (13) by means of said punching die (8) can be returned to the correct position, or approximately to the correct position in the perforation (16) produced in the preform (13) by the punching process to fill said perforation.

摘要： The invention relates to a method that is used to produce a press-hardened molded part (3) having at least two regions that differ regarding the strength of the regions by means of a press-hardening tool. A blank heated to a forming temperature is formed in the press-hardening tool and held in the press-hardening tool during the cooling for the purpose of heat-treating. In order to set the regions of lower strength, said regions are cooled more slowly than the other regions. During the forming step, the entire blank and thus also the regions of the blank intended to be set to a lower strength are in contact with a molding surface of the tool (1). After the conclusion of the forming step, the tool surface (2) in contact with the molded part is changed in such a way that the one or more regions to be set with lower strength have no tool contact during the cooling step that follows the forming step. According to the invention, the tool surface associated with the one or more regions of lower strength of the molded part (3) is formed by tool segments (5.1, 5.2, 5.3, 5.4) that can be adjusted relative to the remaining tool surface and the tool segments (5.1, 5.2, 5.3, 5.4) are adjusted after the forming step in order to change the tool surface (2), and the molding side of the one or more tool segments (5.1, 5.2, 5.3, 5.4) that forms the molding surface for the forming process is larger than the region of the molded part that is to be set with lower strength and that is associated with such a tool segment (5.1, 5.2, 5.3, 5.4). The invention further relates to a press-hardening tool having a shaping surface (2) for producing a press-hardened molded part (3) having at least two regions that differ regarding the strength of the regions. According to a first alternative, the tool surface associated with the regions of lower strength is formed by tool segments (5.1, 5.2, 5.3, 5.4) that can be adjusted relative to the remaining tool surface, and the molding surface of the one or more tool segments (5.1, 5.2, 5.3, 5.4) that forms the molding surface (6.1, 6.2, 6.3, 6.4) for the forming process is larger than the region of the molded part that is to be set with lower hardness due to strength by means of such a tool segment (5.1, 5.2, 5.3, 5.4).
摘要翻译：本发明涉及一种用于生产加压硬化的模制件（3）的方法，所述模压件（3）具有通过加压硬化工具对区域强度不同的至少两个区域。在加压硬化工具中形成加热到成形温度的坯料，在冷却过程中，为了进行热处理而将其保持在加压硬化工具中。为了设定较低强度的区域，所述区域比其他区域冷却得更慢。在成形步骤期间，整个坯料以及因此也将要设置为较低强度的坯料的区域与工具（1）的模制表面接触。在形成步骤结束之后，与模制部件接触的工具表面（2）以这样的方式改变，使得设置为较低强度的一个或多个区域在形成之后的冷却步骤期间没有工具接触步。根据本发明，与模制部件（3）的较低强度的一个或多个区域相关联的工具表面由可相对于剩余的工具表面调节的工具段（5.1,5.2,5.3,5.4）形成，并且在成形步骤之后调整工具段（5.1,5.2,5.3,5.4）以便改变工具表面（2）和一个或多个刀具段（5.1,5.2,5.3,5.4）的模制侧，以使得形成用于成型工艺的成型表面大于要被设置为具有较低强度且与这种刀具段相关联的成型部件的区域（5.1,5.2,5.3,5.4）。本发明还涉及一种具有成形表面（2）的加压硬化工具，该成形表面用于生产具有至少两个区域的加压硬化的模制件（3），所述区域的强度不同。根据第一替代方案，与较低强度区域相关联的工具表面由可相对于剩余工具表面调整的工具段（5.1,5.2,5.3,5.4）形成，并且一个或多个形成成型工艺的成型面（6.1,6.2,6.3,6.4）的工具段（5.1,5.2,5.3,5.4）大于由于强度由于强度而被设定为较低硬度的成型部件的区域这种工具段的手段（5.1,5.2,5.3,5.4）。
