As used in the description of the present invention, the terms "front," "back," "left," "right," "up," "down" and "in" refer to directions in the drawings, and the terms "inner" and "outer" refer to directions toward and away from, respectively, the geometric center of a particular component.

The specific implementation mode of the invention provides a wire drawing roller-type die, as shown in fig. 1, which is a schematic structural diagram of an embodiment of the invention, and the roller-type die comprises a roller-type die device and a limiting guide wheel device.

The roller type die device comprises at least one roller unit, the roller unit comprises at least two roller type die guide wheels 5 which are symmetrically distributed along the axial direction of the roller unit, and the roller type die guide wheels 5 are tangent to the axial direction of the roller unit. In this embodiment, the roller unit is provided with two, and every roller unit is equipped with three roller type mould guide pulleys 5 that become 120 degrees each other, and two roller units stagger 60 degrees each other along the axial, play the effect of drawing rolling evenly to the wire rod. The roller-shaped die guide wheel 5 is rotatably connected with a roller-shaped die guide wheel shaft 7 through a roller-shaped die guide wheel bearing 6, and two ends of the roller-shaped die guide wheel shaft 7 are assembled on the frame at an angle of 90 degrees, so that the roller-shaped die guide wheel shaft 7 is uniformly stressed in the wire drawing process, and the structural strength of the wire drawing machine is ensured. Each roller-type die guide wheel shaft 7 is provided with a position adjusting component for adjusting the radial and axial positions of the roller-type die device so as to adapt to metal wires 1 of different specifications and carry out routine maintenance operation. And a lubricating oil channel is arranged in each roller unit and used for oil pressure lubrication and cooling.

The limiting guide wheel device is arranged in front along the axial direction of the roller type die device and comprises at least three limiting guide wheels 2 which are distributed oppositely, and the limiting guide wheels 2 are tangent to the axial direction of the roller wheel unit. In this embodiment, spacing guide pulley 2 is equipped with threely, and wherein two are located 1 tops of wire rod, and one is located 1 bottoms of wire rod, and the spacing alignment of three spacing guide pulley 2 makes wire rod 1 between the spacing guide pulley 2 is in steady operation state about being located, reduces and rocks the phenomenon, and plays certain alignment. The limiting guide wheel 2 is rotatably connected with a limiting guide wheel shaft 4 through a limiting guide wheel bearing 3, and the limiting guide wheel shaft 4 is fixedly arranged on the rear iron plate. Each limiting guide wheel shaft 4 is also provided with a position adjusting part for adjusting the distance between the upper limiting guide wheel 2 and the lower limiting guide wheel 2 so as to be convenient for installation, maintenance and adaptation to metal wires 1 of different specifications.

In this embodiment, the roller die device is made of wear-resistant hard alloy steel. When the metal wire 1 sequentially passes through the limiting guide wheel device and the roller-type die device, the limiting guide wheel 2 and the roller-type die guide wheel 5 are in rolling friction with the metal wire 1, so that the external force of the metal wire 1 acting on the roller-type die guide wheel 5 is greatly reduced; because the roller-shaped die guide wheel 5 is in rotation, the stress on the inner surface of the roller-shaped die guide wheel 5 is uniform, the problems of local uneven stress, high temperature and abrasion are reduced, and the service life of the roller-shaped die guide wheel 5 is prolonged. The peripheral surface of the outer wheel of the roller-shaped die guide wheel 5 is provided with a wheel groove which is contacted with the metal wire 1, and the wheel groove can be arranged into an arc groove, a triangular groove, a square groove and a polygonal groove according to the processing shape of the metal wire 1.
