Thrust compound power device and method for producing special-shaped wire using the device

Abstract

The invention discloses a thrust composite power device and method applying the same for producing specially-shaped wire materials. The device comprises a rack, a drawing die, a forming die, a plurality of roll wire-pushing mechanisms and a drive mechanism, wherein the plurality of roll wire-pushing mechanisms are transversally arranged in parallel; the plurality of roll wire-pushing mechanisms are located between the drawing die and the forming die, and a transmission gear disc is connected between the adjacent roll wire-pushing mechanisms; the drive mechanism drives one transmission gear disc to rotate. According to the device disclosed by the invention, a wire feeding mode of roll wire-pushing is adopted, and moreover, the wire materials are pushed in the forming die, and a tension device does not need to be configured at the outlet of the forming die, and thus simplifying the overall device; working procedures are reduced in a manner of combining rolling with die drawing, and thus increasing the working efficiency, and reducing the working intensity and labour amount of working personnel; meanwhile, specially-shaped steel wires with great width-thickness ratios and complex shapes can be produced through reasonable collocation of multi-pass rolling, so that the varieties of the producible specially-shaped steel wires are increased, and the shape and dimension accuracies of the products are high.

Description

technical field [0001] The invention relates to the technology in the field of wire rod production, in particular to a thrust compound power device and a method for producing special-shaped wire rods using the device. Background technique [0002] There is a large amount of friction work that is unfavorable to metal deformation in the drawing process of traditional drawing technology. To overcome these invalid friction forces will consume a lot of energy and increase the difficulty of the deformation process; on the other hand, due to the limitation of the drawing process, Drawn products have defects such as central cracks and surface cracks, peeling, pitting, burrs, and uneven mechanical properties of the inner and outer layers. Therefore, it is imperative to develop new drawing technology and research on new drawing theory, expand product varieties and specifications, improve product precision, and reduce product defects. In order to overcome the shortcomings of fixed die...
