Description
Technical field
The present invention relates to the processing of cylinder, relate in particular to a kind of processing method of ultra-large type cylinder, be specifically applicable to ensure axiality, the expansion scope of application at cylinder two ends, can be used for some and be not easy to the directly processing of the large-scale cylinder of processing.
Background technology
Cylinder is mainly a kind of structure for depositing or be wound around hawser, flexible pipe etc., and it can not work alone, and general both sides are by rack support, and drum shaft is provided with bearing with frame junction, and cylinder freely be rotated according to design needs under power drive.Its agent structure is generally cylindric, and side plate is equipped with in both sides, can allow multi-lay winding.
Cylinder may, due to self or external cause, as impacts such as machining accuracy, installation accuracy, external impact, can cause cylinder two ends disalignment in rotation process.If the axiality at cylinder two ends has exceeded the permissible value of bearings at both ends, may cause cylinder to rotate slowly, even stuck, the appearance of this situation easily causes the paralysis of the whole equipment at cylinder place.In addition, due to size (generally can reach Φ 10m × 6m, even the reach Φ 12m × 8m) restriction of large-scale cylinder, if be directly processed into shape, process equipment, processing place and transporting equipment are had to very high requirement.
Summary of the invention
The object of the invention is to overcome the axiality that cannot ensure cylinder two ends that exists in prior art, to process equipment and the higher problem of site requirements, provide a kind of and can ensure the axiality at cylinder two ends and the processing method to process equipment and the lower ultra-large type cylinder of site requirements.
For realizing above object, technical scheme of the present invention is as follows:
A processing method for ultra-large type cylinder, the method comprises the following steps successively:
Making roller axle: adopt vertical lathe to process the bearing installation position that is positioned at drum shaft one end;
Mounting rotary drum body: the outside that barrel is set in to drum shaft;
Welding reference block: adopt boring machine in central authorities' welding reference block of barrel sidepiece, the upper and lower datum level of this reference block and the Central Symmetry setting of drum shaft, arrange vertical with upper and lower datum level of vertical datum level of reference block;
Processing pivoting support installation position: adopt boring machine to process the pivoting support installation position that is positioned at the barrel other end;
Welding: at two ends, the corresponding welding in the top conical plate of barrel, the joint of barrel.
Described barrel comprises point cylindrical shell of multiple equal diameters;
Described mounting rotary drum body step refers to: first in the inside, butt end for the treatment of of point cylindrical shell, support ring is set, then will behind the adjacent outside of dividing cylindrical shell to be placed on drum shaft, be coaxial docking.
Compared with prior art, beneficial effect of the present invention is:
1, the processing method of a kind of ultra-large type cylinder of the present invention comprises processes the bearing installation position that is positioned at drum shaft one end with vertical lathe, with boring machine in the central authorities welding reference block of barrel sidepiece, with boring machine to being positioned at the step of pivoting support installation position of the barrel other end, the method utilizes the processed edge of lathe to ensure the cylindricity of bearing installation position, surface roughness, dimensional tolerance and form and position tolerance, on carrying out when the utilization of reference block is convenient to pivoting support is installed, under, left, right correction, boring machine can process high-precision pivoting support installation position, ensure the axiality at cylinder two ends.Therefore, the present invention has ensured the axiality at cylinder two ends.
2, the processing method intermediate roll body of a kind of ultra-large type cylinder of the present invention comprises point cylindrical shell of multiple equal diameters, add man-hour, first in the inside, butt end for the treatment of of point cylindrical shell, support ring is set, to behind the adjacent outside of dividing cylindrical shell to be placed on drum shaft, be coaxial docking again, this design is processed after larger-size barrel is split as to point cylindrical shell that multiple sizes are less, not only ensure the cylindricity of whole barrel, and without adopting superhuge process equipment, requirement to processing place is lower, effectively having reduced processing drops into, simultaneously, this method can be used in the cylinder of processing various sizes, its scope of application is wider.Therefore, the present invention has not only reduced processing input cost, and has expanded the scope of application.
Brief description of the drawings
Fig. 1 is the structural representation of intermediate roll of the present invention.
Fig. 2 is intermediate roll of the present invention location and machining benchmark schematic diagram.
In figure: barrel 1, point cylindrical shell 11, drum shaft 2, bearing installation position 21, reference block 3, pivoting support installation position 4, conical plate 5, joint 6.
Detailed description of the invention
Below in conjunction with brief description of the drawings and detailed description of the invention, the present invention is further detailed explanation.
Referring to Fig. 1, Fig. 2, a kind of processing method of ultra-large type cylinder, the method comprises the following steps successively:
Making roller axle: adopt vertical lathe to process the bearing installation position 21 that is positioned at drum shaft 2 one end;
Mounting rotary drum body: the outside that barrel 1 is set in to drum shaft 2;
Welding reference block: adopt boring machine in central authorities' welding reference block 3 of barrel 1 sidepiece, the upper and lower datum level of this reference block 3 and the Central Symmetry setting of drum shaft 2, arrange vertical with upper and lower datum level of vertical datum level of reference block 3;
Processing pivoting support installation position: adopt boring machine to process the pivoting support installation position 4 that is positioned at barrel 1 other end;
Welding: at two ends, the corresponding welding in the top conical plate 5 of barrel 1, the joint 6 of barrel 1.
