Abstract

The invention discloses a flatting machine on a spiral pipe production line, and relates to the technical field of spiral pipe machining. The flatting machine comprises a machine frame, a pre-pressing mechanism, a shape adjusting mechanism and a leveling mechanism; the pre-flatting mechanism comprises two pre-flatting rollers arranged in the machine frame, and two sections of spiral embossments are arranged on the circumferential face of each pre-flatting roller and are opposite in rotating direction; the shape adjusting mechanism comprises two roller seats arranged in the machine frame, the roller seats transversely move in the machine frame and are internally provided with conical rollers, and the conical ends of the two conical rollers are arranged oppositely; and the leveling mechanism comprises a plurality of bottom rollers arranged in the machine frame and a top support arranged above the bottom rollers in a lifting mode, and a plurality of top rollers are arranged on the bottom face of the top support in a rotating mode. By means of step-by-step pre-pressing, leveling and shaping, rapid flatting of strip steel is achieved, it is guaranteed that the thicknesses of all points of the strip steel from the middle to the two sides thereof are consistent, the thicknesses of the pipe walls are consistent after the strip steel is machined into spiral pips subsequently, and the quality of the spiral pipes is improved.

Description

technical field [0001] The invention relates to the technical field of spiral pipe processing, in particular to a flattening machine on a spiral pipe production line. Background technique [0002] Spiral pipe is a relatively common type of steel pipe, which is made by rolling low-carbon structural steel or low-alloy structural steel strip into a pipe blank according to a certain helical angle (called forming angle), and then welding the pipe seam. , it can produce large-diameter steel pipes with narrower strips, and it has a wide range of uses. Spiral pipe production process includes: uncoiling - flattening - butt welding - fine flattening - milling - delivery - internal and external welding - cutting. [0003] Since the raw material used for the spiral pipe is strip steel, after the strip steel is produced from the steel factory, the tensile strain on the surface and the irregular slip line generated by the stretching during the stretching process lead to the deviation of ...
