    • For subjecting a continuous strip of metallic-material or stock to an applied high tension for a drawing, straightening or stretching process, apparatus is disclosed which comprises a pair of elastic ring-equipped roll assemblies for holding the material there-between under a high tension applied by the roll assemblies. The elastic ring (5,6) of each roll assembly is capable of elastic deformation which elongates the area of the ring in contact with the material (13) along the circumference of the ring as applied tension increases, thus increasing the contact area over which the applied force is distributed evenly. This results in a reduction of the force per unit area. Each elastic ring is mounted on a shaft (1,2), at least one of the shafts being drivable, byway of atleastthree rollers (3,3a 3b; 4, 4a, 4b) which are interposed between the ring (5,6) and shaft (1,2) for axial rotation and two of which (3, 3a; 4, 4b) are arranged to bridge the ring overthe ring contacting area ofthe material.
    • 为了使金属材料或原料的连续带材施加高拉力用于拉伸,矫直或拉伸过程,公开了一种装置,其包括一对带弹性环的辊组件,用于在高压下保持材料 由辊组件施加。 每个辊组件的弹性环(5,6)能够弹性变形,当施加的张力增加时,弹性变形沿着环的周边延伸环与材料(13)接触的面积,从而增加接触面积 施加力均匀分布。 这导致每单位面积的力的减小。 每个弹性环安装在轴(1,2)上。 所述至少一个所述轴可驱动,所述至少三个辊(3,3a 3b; 4,4a,4b)被插入在所述环(5,6)和所述轴(1,2)之间用于轴向旋转,并且 其中两个(3,3a; 4,4b)布置成将环环绕在材料的环接触区域上。

    • Apparatus for the cold working or hot rolled steel rod comprises a set of freely rotatable pulleys (18, 20) around which the rod runs. The set of pulleys as a whole is driven for orbital revolution. The rod is twisted in one direction as it enters the pulley system and is untwisted as it leaves. The rod is pulled through the pulley system by a rotatable coiler downstream of the system against braking effort imparted to the rod upstream of the system whereby the rod is pulled through under tension. Drive (24,26) for the orbital motion is from the coiler such that the orbital speed and rod feed are in a fixed relationship. Control of the transverse dimensions of the rod is imparted by a sensor downstream of the pulley system, the output from which is used to adjust the tension imparted by the braking pulley (34). The apparatus operates also to descale and straighten the rod continuously and is particularly useful in the production of steel rod for welded mesh in reinforcing concrete.
    • 用于冷加工或热轧钢棒的设备包括一组可自由旋转的滑轮(18,20),杆围绕该滑轮运行。 整套滑轮被驱使进行轨道运转。 当杆进入滑轮系统时,杆在一个方向上扭曲,并在离开时解开。 杆通过系统下游的可旋转卷取机被拉动通过滑轮系统,以抵抗施加到系统上游的杆的制动作用,由此杆在张力下拉动通过。 用于轨道运动的驱动器(24,26)来自卷取机,使得轨道速度和杆馈送处于固定关系。 杆的横向尺寸的控制由滑轮系统下游的传感器传递,滑轮系统的输出用来调节制动滑轮(34)施加的张力。 该设备还可以连续地除锈和拉直棒材,并且特别适用于钢筋混凝土中用于焊接网格的钢棒的生产。
