Description

用于制造具有齿排的调节机动车座椅用的构件的方法
技术领域
本发明涉及一种用于制造具有齿排(Zahnreihe)的调节机动车座椅用的构件的方法。
背景技术
这样的构件是精密构件，其通过精密切削以及接下来借助于热处理而硬化来制造。该当前的制造方法的缺点尤其在于，通过成型过程在成品中产生较大的固有应力，其在热处理之后导致构件的不受控制的尺寸偏差。此外，由于这两个严重分离的制造过程-精密切削和热处理-需要提高的物流耗费，其引起较高的制造总成本。此外不利的是在该制造中产生的冲压收缩(Stanzeinzug)，其导致承载力的损失。
发明内容
本发明的目的是提供一种方法，利用其来消除这些缺点。
该目的根据本发明利用一种具有权利要求1的特征的方法来实现。
通过根据本发明的方法可消除前面提到的缺点。尤其可通过齿排的切削和直接成型(压印)使在该区域中由于材料流的冲压收缩减小到最小。另外的优点可在于能干减小构件的尺寸偏差。此外，通过根据本发明的方法可比在精密冲压时覆盖更大的部件范围(Teilespektrum)，因为精密冲压受自动冲压机尺寸限制。
在本发明的有利的设计方案中构件在顺序复合过程(Folgeverbundprozess)中由卷圈(Coil)制造完成，也就是说，构件就地被制造完成。由此取消根据现有技术必需的物流耗费，这导致成本下降。
附图说明
接下来根据实施例来详细阐述本发明。属于此的附图示出：
图1以俯视图示出顺序复合工具的条带图(Streifenbild)，
图2示出用于执行第一方法变体的工具的示意图，以及
图3示出用于执行第二制造变体的工具的示意图。
具体实施方式
利用根据本发明的方法来制造构件1，其用于机动车座椅的高度调节。其具有齿排2，在未示出的安装状态中小齿轮与齿排啮合，通过小齿轮的驱动来引起构件1的调整运动。
接下来说明两个方法变体。在两个方法变体中将带3从未示出的卷圈拉出且输送给各个工序。
在第一方法变体中将构件1在顺序复合过程中逐步地切削和成型。其在齿排2的制造之前具有大约匙形，其带有柄区域1.1和一件式地接着的更宽的功能区域1.2。在功能区域1.2中通过切削和成型使齿排2构造有粗轮廓，然而其还具有一定的尺寸不足(Untermass)或预留尺寸(Vorhaltemass)。该区域然后在图2中所示的工具4中被感应加热且在压印冲头(Praegestempel)5与型模(Matrize)6之间被压印到齿排2的最终轮廓上。在此，材料流动到缺陷部位中，使得冲压收缩在该区域中被减小到最小。在该阶段(其在根据图1的条带图中以A表示)中，同时也实现将热的构件1冷却到一定的温度上用于组织转变。在使该构件在最后的校正阶段成型到最终几何结构上且从带3处分离成成品之前，接下来的方法阶段设置用于构件1的进一步冷却。
在第二方法变体中也将构件1在连续复合过程中逐步地切削和成型。然而在此不制造齿排2的毛坯形状(Rohform)，而是将构件1的功能区域1.2感应加热。然后在下一方法阶段中将齿排2切削到最终尺寸上。在该阶段(其在根据图1的条带图中以B表示)中，同时也实现热的构件的冷却。图3图解地示出用于执行该方法阶段的工具7。构件1以加热的功能区域1.2被夹紧在工具下部件8与剪切冲头9之间。然后使剪切冲头9向下压靠工具下部件8，由此切削出齿排2的最终轮廓。在剪切冲头9中可轴向移动地支承有抛出器(Auswerfer)10，其将切削完成的构件1从剪切冲头9中压出。在该过程中位于工具下部件8上的待被移除的冲压废料1.3累积。
接下来的方法阶段如在第一方法变体中那样设置用于构件1的进一步冷却。
