An automatic drawing device for forming a round tube into a square tube at one time

Abstract

The invention discloses an automatic drawing device for drawing a round tube into a square pipe at one time, in order to solve the problem that the existing drawing device cannot draw the round tube into the square pipe at one time. The automatic drawing device comprises a rack and a fixture on the rack, wherein the fixture comprises a left fixture, a right fixture and an upper fixture, the distance between the left fixture and the right fixture is adjusted through a horizontal adjusting mechanism, the distance between the left fixture and the right fixture is adjusted by the upper fixture through a vertical adjusting mechanism, the upper fixture, the left fixture and the right fixture form a passage, a mold is arranged in the passage, a guide bottom plate with both ends fixedly connected with the rack is arranged below the mold, fastening devices are arranged at both ends of the mold, one end of the mold is connected with a motor arranged at the outside of the rack through a wirerope, and the mold is driven by the motor to move in the passage, and a fixation clamp fixedly connected with one end of a pipeline is arranged on the rack. The device disclosed by the invention can draw the round tube into the square pipe in a drawing process, thereby reducing the technological process and improving the working efficiency.

Description

technical field [0001] The invention belongs to the field of metal material processing, and in particular relates to an automatic drawing device for one-time forming of a circular tube into a square tube. Background technique [0002] Drawing is hot-rolled, welded pipe or cold-rolled pipes of different lengths as raw materials, combined with different mandrels, using a drawing machine to produce plastic deformation at room temperature through a drawing die without cutting. Precision, high quality, high strength tubing. High-precision thin-walled pipes are widely used in daily life, so the processing requirements for them are also very high. The drawing machine is one of the important equipment for pipe drawing. It uses the wire rope to work reciprocally. Its function is to change the diameter of the pipe to obtain the pipe diameter required by production. In recent decades, when studying many new drawing methods, research on high-speed drawing has been carried out, and mul...

Problems solved by technology

[0004] The invention provides an automatic drawing device for one-time forming of a round tube into a square tube, which solves the problem that the existing drawing machine can only realize the drawing of the round tube, but cannot draw the round tube into a square tube. The drawing of the small drawing team cooperates with the inner mold and the outer mold. During the drawing process of the round pipe, the round pipe is turned into a square pipe while ensuring the quality of the pipe drawing, and the round pipe is further processed.
