Tensile straight-line drawbench

The utility model relates to a mechanical device used for drawing cored wires and in particular relates to a tensile straight-line drawbench which comprises a workbench, a take-up machine, a plurality of drawing dies and a plurality of tapered electric speed regulating drums. All the drawing dies are provided with lighting holes; solid lubricating containers are arranged at the wire inlet ends of all the drawing dies; the drawing dies are fixed on the workbench sequentially by taking the centerline of the lighting holes as the datum; and the tapered electric speed regulating drums are arranged among the drawing dies. Wires thread through the drawing dies and then enwind the electric speed regulating tapered drums for certain loops and enter the next group of drawing dies, and finally the finished wires are coiled to be a disc by the take-up machine. The utility model aims to provide a tensile straight-line drawbench which has the advantages that the cored wires are not easy to break during the radial-contracting drawing process and the core powder can be filled evenly and compactly. Compared with the prior art, the tensile straight-line drawbench is high in production capacity and has no phenomena of breakage, shrinkage and torsion during the production, and the cored wires produced by the drawbench are good in molding effect and have smooth surfaces.
