Abstract

The invention discloses a circle correcting device for a welded steel pipe. The circle correcting device comprises a rack, two steel-pipe-end fixing devices are symmetrically arranged on the rack, an external-circle correcting mold is arranged between the two steel-pipe-end fixing devices, and the steel-pipe-end fixing devices and the external-circle correcting mold are all arranged on a guide rail of the rack, and can move along the guide rail; each steel-pipe-end fixing device comprises a base and a fixing head, each fixing head is rotatably connected on one side of the corresponding base, a groove is formed in the middle of each fixing head, and a plurality of retractable arc pressing plates are evenly arranged on the inner side wall of each groove at intervals; a lead screw is mounted in the middle of each groove, a rounding mold is fixed to one end of each lead screw, and the other end of each lead screw extends out of the end of the corresponding steel-pipe-end fixing device and is driven by a motor to rotate. According to the circle correcting device for the welded steel pipe, all-sided circle correcting is conducted on the whole steel pipe, moreover, the steel pipe does not need to be moved and fixed again, and thus the efficiency is enhanced.

Description

technical field [0001] The invention relates to the technical field of mechanical equipment, in particular to a circle calibration device for welded steel pipes. Background technique [0002] Steel pipes need to be rounded during the production process. For steel pipes with different diameters and different lengths, during the rounding process, general equipment cannot realize the simultaneous rounding of the outer circle and the inner circle. It needs to be done separately, which is very inconvenient and efficient. lower. Contents of the invention [0003] The technical problem to be solved by the present invention is that in the existing steel pipe circle calibration, the outer circle and the inner circle cannot be calibrated at the same time, and need to be done separately, which is very inconvenient and low in efficiency. [0004] In order to solve the above-mentioned technical problems, the present invention provides a welded steel pipe rounding device, including a f...
