Technical field
The invention belongs to the secondary process equipment technical field of huge revolving equipment ball mill barrel, specifically, relate to a kind of large cylinder apparatus for rotating middle cylinder bodies such as metallurgy, the various rotary kilns of mine class, grinding machine, mixer that are widely used in and roll the improvement of imitating shape, changeing the anti-deformation support device structure of order, cylindrical shell and shell flange, wheel band process.
Background technology
Ball mill is one of large-scale mill, broken equipment, is widely used in the mining processing industry.Its structure mainly by barrel, form for ore deposit portion, ore discharge portion, bearing portion, driving section and lubricating system six parts; Its operation principle is that motor rotates by the cylindrical shell that the driving section drives rotating part, abrasive media-the steel ball that is contained in the cylindrical shell moves to certain altitude under frictional force and centrifugal action, leave by certain linear velocity then, the fallen bump of steel ball of ore, and by between steel ball and the steel ball, and the additional crushing between steel ball and the grinding machine and mill stripping effect and pulverize, and by means of the impulse force of water, the qualified material that grinds is sent outside the cylindrical shell.Cylindrical shell is as the main huge revolving parts of driving section, and the workmanship of its cylindrical shell directly affects work quality and the service life of grinding machine, also determines the key of the continuous smooth operation of grinding machine integral device.
In recent years, along with the maximization of grinding machine kind equipment master-plan specification and complicated, manufacturing and the crudy of grinding machine integral body there has been higher requirement.Therefore, keeping cylindrical shell to roll, change circularity and distortion in order, the cylindrical turning process, is whether continuously to determine under the grinding machine duty prerequisite of smooth operation.At present, existing large-sized grinding mill barrel diameter reaches φ=6500mm, and the cylindrical shell effective length is L=9000mm.Along with the increase of barrel diameter, the increase of length, the equipment that cylindrical shell processing is used also is tending towards maximizing, and the purchasing price costliness of main equipment has improved the cylindrical shell processing cost virtually; Circularity owing to the cylindrical shell manufacturing directly influences the whole turning course rotating speed of grinding machine simultaneously, so the manufacturing issue of cylindrical shell is the bottleneck problem that needs to be resolved hurrily of present grinding machine manufacturing.
Shell ring is the elementary cell of forming cylindrical shell, and it is the steel plate by the thick specification of δ=40-60mm, is welded behind the pre-roll-forming; It is to be formed by the shell ring jointing behind several welding fabrications for cylindrical shell, is welded with the stiff end flange at the two ends of cylindrical shell, and end flanges is connected with the charging and discharging portion at two ends, the left and right sides respectively, and it is whole to form unified revolution.Cylindrical shell is as parts maximum in the ball mill, pivoting part, Optimal Structure Designing, the reasonability of use and the economy of manufacturing of its a series of large-scale combined anti-deformation tool in the processing of the jointing of the rolling of shell ring, cylindrical shell, end flanges, cylindrical shell handling, process of transfer order, directly affect work quality, service life and the manufacturing cost of grinding machine, therefore each link of a strict application cylinder body shell ring manufacturing process is most important.
