Embodiment Construction
[0027] The preferred embodiments of the present invention will be described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.
[0028] Such as figure 1 As shown in the present invention, a device for compulsively correcting the side error of the container cylinder, including:
[0029] Frame 1, the bottom of the frame 1 is provided with wheels, and as a preferred solution, the bottom of the frame 1 is provided with a conveying trolley 13 whose height can be adjusted. Conveying trolley 13 comprises top plate, two articulated frames and wheels that are located at the bottom of top plate, and wheel is arranged on the bottom end of described articulated frame, and the hinge portion of articulated frame is provided with a bolt as hinge shaft, and the end of described bolt is screwed into the devic...

The invention provides a container barrel misalignment error forced correction device which comprises a rack. The container barrel misalignment error forced correction device further comprises a conical shaft capable of doing reciprocating motion relative to the rack, a numerical control bearing rotary disc arranged in a manner of being coaxial with the conical shaft and fixed to the conical shaft, and an ejection column assembly comprising a first sliding wheel arranged at the first end of an ejection column and an ejection block arranged at the second end of the ejection column; the rack is provided with a first guide hole for guiding the ejection column; the ejection column is arranged in the first guide hole in a sliding manner, and the first sliding wheel is in contact with a conical head of the conical shaft. By means of the above structure, barrel circular seam misalignment errors are subject to multi-arc-section, multi-position and equal-round internal expanding correction, rapid, damage-free, 360-degree and high-accuracy correction operation on the barrel circular seam misalignment can be completed, and the barrel circular seam high-quality welding requirement is met.
Description
technical field [0001] The invention relates to a correcting device, in particular to a device for compulsively correcting the edge error of a container cylinder. Background technique [0002] In the development of oil and gas fields, various types of pressure vessels, pile legs, pressure transmission pipelines and other devices are widely used. During the manufacturing process of these devices, it is necessary to assemble the single-section cylinders. The error and its own weight will cause the two groups to weld the circular seam of the cylinder, and the misalignment of the circular seam of the cylinder will often appear out of tolerance (greater than 5mm), which cannot meet the technical requirements of the circular seam welding. The circular seam welding operation can be carried out only when the error of the misalignment of the circular seam is reduced to the allowable range. Usually, the forced correction method is used to cause elastic or plastic deformation at the c...
