Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
As shown in Figure 1.The utility model volume arc machine is made up of frame 5, main drive roll axle 6, auxiliary drive roller shaft 1, jack 2, motor 4 and drive, chain 3.Frame 5 comprises straight-bar machines frame, upper vertical frame and lower fixed frame, and upper vertical frame is vertically fixed on the middle part of straight-bar machines frame, and upper straight-bar machines frame, upper vertical frame are fixed on lower fixed frame.Two auxiliary drive roller shaft 1 are arranged on upper straight-bar machines frame respectively by two auxiliary drive roller shaft 1 in left and right symmetry, the middle part of two auxiliary drive roller shaft 1 is provided with roll shaft groove, two auxiliary drive roller shaft 1 are fixedly connected with upper straight-bar machines frame by bolt nut, and two auxiliary drive roller shaft 1 are 50 roll shafts.Main drive roll axle 6 is arranged in upper vertical frame by main drive roll axle bed, and main drive roll axle 6 is 50 roll shafts, and main drive roll axle bed is fixedly connected with upper vertical frame by bolt nut, to carry out intermode apart from regulating.Jack 2 is arranged between main drive roll axle bed and upper vertical frame, and jack 2 is one, hand oil-pressure type 16 tonnes of jack, and minimum stroke height is 225mm, highest line journey height is 425mm, lifting altitude is 140mm, adjustment height 60mm, rated load weight 160 KN.Motor 4 is connected with main drive roll axle, and is connected with two auxiliary drive roller shaft 1 by drive, chain 3, and motor 4 is one, 0.75KW tri-asynchronous motors.Following advantage is there is: 1, installation, convenient disassembly with threephase asynchronous; 2, threephase asynchronous speed comparatively slow, steadily, can synchronous axial system, guarantee the even transmission of each transmission portion in rotation process, safe and reliable.Motor 4 is fitted with cycloidal planetary gear speed reducer, selects 0.75KW cycloidal planetary gear speed reducer to be drive disk assembly, guarantee the even transmission of each transmission portion in rotation process, safe and reliable.
Rolling of angle ring: before rolling, by two sections of angle steel back-to-back spot welding get up; Spacing between adjustment main drive roll axle 6 and two auxiliary drive roller shaft 1 is 300-400mm, and when mainly preventing from rolling, the angle steel generation changing of the relative positions forms patellate and angle steel deflecting angle steel ring plane; When rolling, put in roll shaft groove by putting the angle steel that welds, along with the rotation of roller, angle steel plane and roller generation opposing compression and motion, make angle steel bending, and form circular arc gradually, after rolled forming, then by spot welding well angle steel together cut open.
There is following advantage in the utility model volume arc machine: 1, the preparation of construction time is short, labour is few; 2, little, the convenient in carrying of overall volume, effectively reduces construction cost.
For avoiding occurring that straight flange can take following measures rolling in angle steel: a, the angle ring docking assembly welding of straight flange will be there is, and according to radian model school circle on volume arc machine.Even if be slit into several sections on demand after the circle of school also can not be out of shape.B, made allowance.After rolling into certain circular arc, straight flange is sliced off, would not straight flange be occurred at continuation volume.C, roll before, designing mould pressure head.
