Abstract

The invention discloses a special-shaped steel drawing method and a drawing device, wherein the drawing method includes the following steps: step 1, preparing a plurality of special-shaped steel extension pipes with different diameters and specifications, wherein the maximum diameter of the extension pipe is the target special-shaped Steel pipe size; step 2, put the inner module into the extension tube of the corresponding size in turn, and put the front end of the extension tube into the outer mold sleeve of the corresponding size; step 3, weld the extension tube to the tube according to the diameter of the tube. The front end of the blank, the inner module and the outer mold cover corresponding to the extension tube are attached to the extension tube; step 4, fix each outer mold cover, and pull the tube blank forward along the axial direction of the tube blank, so that the tube blanks are sequentially Through multiple outer mold sets, the continuous drawing of the tube blank is completed. Through the drawing method in the present invention, the steel pipe to be processed can pass through multiple molds to achieve multiple drawing and shaping through the drawing method in the present invention, and the drawing efficiency is high. .

Description

technical field [0001] The invention relates to the technical field of steel processing, in particular to a drawing method and a drawing device for special-shaped steel. Background technique [0002] With the higher requirements for steel pipes in construction machinery, marine oil and other industries, high-precision, high-performance cold-drawn special-shaped pipes have begun to be widely used. Generally, when cold drawing steel pipes, in order to achieve the dimensional accuracy of the steel pipes, instead of using one-time drawing with large deformation, the steel pipes are drawn multiple times to gradually reach the target size. For the multiple drawing process, in the prior art, the drawing of the steel pipe is performed one at a time, that is, after the first drawing, the mold is replaced, and then the second drawing is performed, and the processing efficiency is low. Contents of the invention [0003] The object of the present invention is to solve the low efficie...
