    摘要： A drawing machine comprising: a first drawing unit that includes a first drawing die, a first upstream capstan that is provided before the first drawing die so as to deliver the metal tube to the first drawing die, and a first downstream capstan that is provided after the first drawing die so as to draw the metal tube from the first drawing die; a second drawing unit that includes a second drawing die that draws the metal tube delivered from the first drawing unit, a second upstream capstan that is provided before the second drawing die so as to deliver the metal tube to the second drawing die, and a second downstream capstan that is provided after the second drawing die so as to draw the metal tube from the second drawing die; and a tension applying section that applies a predetermined tension to the metal tube between the first drawing unit and the second drawing unit.

    摘要： In a method for setting bending of at least one straightening roller in a roller straightening machine, the straightening roller is supported by a plurality of supporting roller devices arranged beside one another in the axial direction, wherein each supporting roller device can be adjusted by an actuating device such that stresses are produced in the straightening roller. To control the actuating device, a control system is provided, by which the adjustment of the supporting roller device can be set manually. Limiting values (vMA, vMI) with respect to the stresses produced in the straightening roller are stored in the control system. In the event of adjustment of one of the supporting roller devices, maxima (MA) and minima (MI) of the stresses produced in the straightening roller are calculated and it is checked whether the maxima (MA) and minima (MI) lie within the limiting values (vMA, vMI).

    摘要： In one aspect, a track shoe assembly may include a shoe plate having a shoe plate body including a shoe plate attachment surface, and at least two slots extending through at least the shoe plate attachment surface. The track shoe assembly may also include a grouser having a grouser body having a grouser attachment surface, and at least two tabs, integrally formed with the grouser body, the at least two tabs extending from the grouser attachment surface, and perpendicular to the grouser attachment surface, the at least two tabs of the grouser being configured to be positioned within the at least two slots of the shoe plate. In another aspect, a method of manufacturing a track shoe assembly may include forming a shoe plate as described above, forming a grouser as described above, and attaching the grouser to the shoe plate to thereby form a track shoe assembly.

    摘要： The present invention relates to an intermediate blank connection system for hot-rolled strip headless rolling and a connection method, and belongs to the technical field of intermediate blank connection for strip steel headless rolling. The connection system and the connection method realize matching of an intermediate blank connection device and speed of a unit through a translation drive system. A mounting frame is used to provide support for cutting devices, and the cutting devices are divided into two groups arranged in the mounting frame to achieve clamping of a front slab and a rear slab respectively. Interlaced dovetail cutting edge structures are used to achieve cutting and ensure a good longitudinal stress state. Finally, a certain difference is set in sizes of width directions between cutting edges, to ensure that there is certain extrusion deformation in a process of forming dovetail cutting groove connection, and enhance a connection effect. At the same time of realizing a good intermediate blank connection effect finally, a structure of the connection device is greatly simplified, and investment and operating cost is reduced.
