Technical Field

The utility model relates to a container field of making, specifically say, relate to a thin wall major diameter reel is rectified and supplementary all-in-one of spot welding.

Background

The plate rolling machine is a very important shaping processing device, has very wide application in the manufacturing industry, and is an indispensable device particularly in the container manufacturing industry.

The cryogenic storage tank and tank car container for storing low-temperature liquid such as liquid oxygen, liquid nitrogen, LNG and the like are widely applied in the aerospace, submarine, gas industry, energy source, transportation, refrigeration and manufacturing industries, and have the characteristics of large diameter and thin wall, the diameter can reach 3m, the wall thickness is generally stainless steel as an inner container, the wall thickness is 5-6mm, the outer container is carbon steel, and the wall thickness is 4-5 mm.

The plate bending machine belongs to primary forming equipment, has plate bending forming errors and is reflected on two aspects, on one hand, the axial deviation, the characteristics of plates in the plate bending process, plate thickness deviation and form and position tolerance, plate uniformity deviation, feeding process deviation, errors of the plate bending machine and other factors cause that the end which firstly enters the plate bending machine after forming is axially staggered with the end which finally enters the plate bending machine, so that the circumferences of the end parts of the winding drum are not in the same plane; on the other hand, the circumferential deviation is that the circumferential direction of the winding drum after the plate is rolled is in a C shape (under-rolling) or a lap (over-rolling) instead of an ideal circle; in actual production, the two forming deviations exist almost without exception for each workpiece, and the deviation has individual specificity and is difficult to adjust and control. The two deviations are very unfavorable for the subsequent process, and the circumferential welding between the winding drum and between the winding drum and the end enclosure is directly influenced because the circumferences of the end parts of the winding drum are not in the same plane; the circumferential deviation influences the longitudinal seam spot welding fixation or the longitudinal welding of the winding drum.

For the thin-wall large-diameter winding drum, the influence is more obvious due to the poor rigidity, and the problem is difficult to solve through trimming, groove arrangement and other modes commonly adopted in the thick-plate winding drum. Therefore, after the thin-wall large-diameter winding drum is rolled and formed, the winding drum must be corrected firstly. The adopted process comprises the following steps: and (5) correcting the winding drum, fixing the winding drum by longitudinal seam spot welding, and longitudinally welding and forming. At present, because no special correction equipment exists, the correction is usually carried out manually through a simple tool, and the following problems exist: (1) manual correction is carried out, multiple persons are required to cooperate, the reliability is poor, the consistency of the corrected winding drum is poor, and the efficiency is low; (2) because the manual correction efficiency is low, the winding drum must be moved out of the plate bending machine for correction, and thus, a plurality of problems exist: the reel which is not fixed by longitudinal seam spot welding has poor rigidity, so that the reel is inconvenient to move out or misplaced to move out, and certain potential safety hazard exists; the reel support is required to be added, the reel needs to be supported and fixed again, the process auxiliary time is increased, and the efficiency is further reduced; the low efficiency causes that a plurality of fields are occupied for reel correction, workshop resources are wasted, the connection of front and rear processes is inconvenient, and the production order is poor; a plurality of fields are corrected, auxiliary correction facilities are added, and the production cost is increased; (3) the proper process and operation specification are difficult to formulate, the experience of workers is more relied on, and the quality stability is poor.

For example, patent publication No. CN 208583840U: a device for correcting the coaxiality and straightness of a boring bar is disclosed, but the device is not suitable for correcting a thin-wall large-diameter drum.

Therefore, it is necessary to design an integrated machine for correcting and assisting spot welding of a thin-wall large-diameter winding drum to solve the above problems.
