    • During the bending of sheet metal sections (1, 2) in particular for forming can edges using a bending machine, the sheet metal is pre-treated at a flexing station (50) before reaching the bending station. The contact position (x, y, y′) of a sheet on a measuring plate (38) is measured and the signal representing the contact position is reproduced on a display (25), enabling the operator to adjust at least one element (7, 8, 9, 20) of the flexing station in accordance with the deviation of the actual contact position from the target contact position, either manually or by means of a drive. The signal can also be used to automatically adjust at least one element of the flexing station.
    • 在钣金件(1,2)的弯曲期间,特别是使用弯曲机形成罐边缘时,金属板在到达弯曲台之前在弯曲台(50)处被预处理。 测量测量板(38)上的薄片的接触位置(x,y,y'),并且在显示器(25)上再现表示接触位置的信号,使得操作者能够调节至少一个元件(7 ,8,9,20)根据实际接触位置与目标接触位置的偏差,手动地或借助于驱动器。 该信号还可用于自动调节弯曲台的至少一个元件。

    • A welding machine with wire electrodes is used to electrically resistance roll seam weld tin plate. Only one electrode wire running over both of the electrode carrying rolls is used. To prevent the formation of a loop in the wire stretch between the electrode carrying rolls a hard wire is required which is produced by a prior rolling of a soft round wire. With this rolling there results however a non-uniform hardness distribution over the wire cross section with areas of high and areas of low material hardness so that the average strength increase over the entire wire cross section of the electrode wire remains below the increase in strength which could theoretically be reached if no portion of the wire cross section remained outside of the area of high material strength. A closer approach to this theoretical increase in strength is achieved instead of rolling, by cold forming in several steps, in which cold forming the round wire is in a first forming stage cold formed to smaller diameter by drawing and thereafter in a second forming stage is cold formed by flat rolling. This brings advantages to the welding process as well as substantial savings in wire.
    • 具有电线电极的焊接机用于电阻辊缝焊锡板。 仅使用在两个电极承载辊上运行的一个电极线。 为了防止在电极承载辊之间的线拉伸中形成环,需要通过软圆线的先前轧制产生的硬线。 然而,通过这种轧制,结果导致在线材横截面上具有高的区域和低材料硬度区域的不均匀硬度分布,使得在电极丝的整个线横截面上的平均强度增加保持在强度增加以下 如果没有线横截面的部分保留在高材料强度的区域之外,理论上可以达到。 实现这种理论上的强度增加的更接近的方法是通过在几个步骤中的冷成型实现的,其中冷成形圆线在冷成形为较小直径的第一成形阶段中,之后在第二成形阶段中被实现 冷轧由扁平轧制成型。 这为焊接过程带来了好处,同时节省了大量的电线。
