Abstract

The invention belongs to the technical field of steel tube straightening and discloses a pre-straightener for production of cold-drawn precision seamless steel tubes. The pre-straightener comprises alongitudinal straightening assembly and a transverse straightening assembly matched with each other. The longitudinal straightening assembly comprises a fixed seat, a longitudinal adjusting mechanismembedded into the fixed seat and two longitudinal straightening rollers symmetrically mounted on a side wall of the fixed seat. The transverse straightening assembly comprises a transverse adjusting mechanism and two transverse straightening rollers symmetrically arranged. The pre-straightener also comprises a transmission assembly which comprises a toothed plate, a gear and a transmission box matched to drive, the toothed plate is fixed to the longitudinal adjusting mechanism and is engaged to the gear, the transmission box is connected to the transverse adjusting mechanism and is driven withthe gear coaxially, so that linked adjustment between the transverse straightening rollers and the longitudinal straightening rollers s is achieved, and therefore, the pre-straightener is more convenient to adjust, the structure adjusting time is saved effectively, and the straightening efficiency is improved indirectly.

Description

technical field [0001] The invention belongs to the technical field of straightening steel pipes, and in particular relates to a pre-straightening machine for production of cold-drawn precision seamless steel pipes. Background technique [0002] In the process of preparing seamless steel pipes, especially seamless steel pipes with fine apertures, since the pipe itself is relatively slender, it is inevitable that the pipe will be bent and deformed, so it needs to be straightened by a straightening machine. The principle of a common straightening machine is to squeeze the steel pipe through the upper and lower straightening rollers to achieve the effect of straightening the steel pipe. Specifically, take a seamless steel pipe straightening machine disclosed in the CN207941827U patent as an example. The straightening machine adopts longitudinal and Horizontal two-way straightening to improve the straightening effect of seamless steel pipes, and the straightening rollers are set...
