The invention relates to the technical field of steel pipe cold drawing, and discloses a cold drawing device for bearing steel pipe machining. The cold drawing device comprises a drawing trolley and a steel frame arranged on the upper surface of the drawing trolley, a clamping assembly and a power assembly, wherein the clamping assembly is fixedly installed at one end of the upper surface of the drawing trolley and comprises a first jaw and a second jaw, the first jaw and the second jaw are hinged to each other and used for clamping a pipe fitting, and the power assembly is fixedly installed on the drawing trolley and comprises a power rod, two check blocks, a driving frame and a connecting frame. According to the cold drawing device, a motor set drives a drawing screw and a drawing block to drive the trolley to move, and the problem that a steel wire rope is mainly concentrated in the center of a winding drum, the steel wire rope has a certain thickness after being wound for multiple circles, the steel wire rope can deviate in the Y-axis direction, and when deviating, the steel wire rope has a certain relaxation time, namely instantaneous speed fluctuation exists, and the drawing speed is not uniform is solved.
Description
technical field [0001] The invention relates to the technical field of cold drawing of steel pipes, in particular to a cold drawing device for processing bearing steel pipes. Background technique [0002] At present, the general equipment for cold drawing of seamless steel pipes is to hammer the rough steel pipes that need to change the diameter and wall thickness. The tip of the hammer, so that the rough steel pipe can protrude from the outer die hole of the cold drawing machine, so that the cold drawing trolley can clamp the hammer head for cold drawing. This process is generally used today. [0003] The general structure of the cold drawing machine is: drawing die assembly, feeding assembly and drawing assembly. The drawing die assembly is mainly a drawing die, which is set between the feeding assembly and the drawing assembly. The steel pipe is drawn by the feeding assembly. Send it into the drawing die, and pass the steel pipe through the drawing die to complete the in...
