Technical Field
The present invention relates to a separation roller.
Background
The high-quality strip steel such as the automobile outer plate and the like needs special treatment in each process stage of cold rolling, is different from the common cold-rolled plate, and has wider breadth. Therefore, cold rolling plants for producing automobile outer plates are wide strip steel production equipment, but a small amount of narrow strip steel is required in the market, and if the wide strip steel is used for producing the narrow strip steel, the production cost is quite high, so that a splitting machine set is required to be installed, namely, the wide strip steel is split into two strips from the middle in the last cold rolling finishing process, and the strips are changed into the narrow strip steel. The longitudinal cutting machine set can complete the longitudinal splitting of the strip steel, but due to the limitation of the longitudinal cutting production process, the yield is far lower than that of a rewinding machine set, and a cold rolling finishing machine set needs a large amount of rewinding checking functions, so the rewinding checking functions and the splitting functions are combined on the same machine set to form a rewinding splitting machine set. The separating roller is a key device applied to the rewinding subdivision production line, when large-scale conventional production of wide-width strip steel is carried out, the subdivision shear and the separating roller quit the working position, and the production line is used as a rewinding unit; when the narrow strips need to be produced, the splitting shears and the separating rollers are put into operation, the splitting shears perform equal-amplitude longitudinal splitting on the strip steel, the separating rollers perform transverse separation on the split strip steel, the phenomenon that the inner side edges of the two narrow strips are scratched to influence the quality of the strip steel and damage equipment is prevented, and the production line is used as a splitting unit at the moment.
The prior strip steel longitudinal separation device mostly adopts tapered rollers, and the separation degree of narrow strip steel in the device is related to the taper and the rolling reduction of the tapered rollers. This form of construction has a serious drawback: because the taper of the tapered roller is not adjustable, the separation performance of the tapered roller only adapts to the fixed thickness range of the strip steel, and the corresponding requirements of the strip steel with different thickness specifications on the separation effect cannot be met, the separation effect is general, the adaptability is poor, and the continuity is poor.
Disclosure of Invention
The technical problem to be solved by the invention is to provide a separation roller to overcome the defects in the prior art. The separating roller is used for meeting the requirements of the production line for the separation effect of the two narrow strips after the strip steel is longitudinally cut and split and the requirements of the strip steel non-splitting continuous production, and can be used for continuously adjusting the convexity of the roller according to the actual separation effect of the strip steel, so that the separating roller is suitable for the requirements of the strip steel longitudinally split and separated with different thickness specifications.
The technical scheme of the invention is as follows:
a separator roll, characterized by: the device comprises a swing frame, a lower arc-shaped roller, an upper press roller, a reduction box, a universal coupling, a speed reduction motor, an air cylinder and a rack; the swing frame is hinged with the rack through a pin shaft, the lower portion of the swing frame is connected with the air cylinder, the upper pressing roller, the lower arc-shaped roller and the reduction box are respectively fixed on the swing frame, a space is reserved between the upper pressing roller and the lower arc-shaped roller, and the reduction box is connected with the speed reduction motor through a universal coupling.
The upper compression roller is a steel-based rubber lining roller, the lower arc-shaped roller is a convexity-adjustable rubber lining roller, two ends of a mandrel of the upper compression roller are flat shafts, the middle part of the mandrel is bent into an arc shape, bearings are arranged on the arc-shaped part at certain intervals, and the outer ring of each bearing is provided with a rubber lining roller with the same radian as the mandrel.
One end of the lower arc-shaped roll is fixed on an operation side bearing seat on the swing frame through a joint bearing, and the other end of the lower arc-shaped roll is fixed on a transmission side bearing seat on the swing frame through a worm wheel and a worm.
The worm is connected with the reduction gearbox through an elastic coupling.
The invention has the technical effects that:

Detailed Description
The invention relates to the field of metallurgical equipment, in particular to strip finishing operation, and discloses a separating roller suitable for a wide strip steel rewinding and splitting production line.
Referring to fig. 1 to 3, a separating roller according to the present invention has a specific structure:
the device comprises a swing frame 3, a lower arc-shaped roller 4, an upper press roller 1, a reduction box 6, a universal coupling 10, a speed reduction motor 11, an air cylinder 9 and a rack 8; wherein,
the middle of the swing frame 3 is provided with a rotating fulcrum, the swing frame 3 is hinged with the rack 8 through a pin shaft 2, the lower part of the swing frame 3 is connected with an air cylinder 9, the upper pressure roller 1, the lower arc-shaped roller 4 and the reduction gearbox 6 are respectively fixed on the swing frame 3, a certain distance is arranged between the upper pressure roller 1 and the lower arc-shaped roller 4, and the size of the distance is determined according to the diameters of the upper pressure roller 1 and the lower arc-shaped roller 4 and the equipment structure. As shown in fig. 1, the spacing functions to: firstly, when the device is put into separation work, the lower arc-shaped roller 4 protrudes to separate strips, and the lower surface of the upper press roller 1 is level with the operating line, so that the device has the functions of keeping the elevation of the operating line and stabilizing strip steel; secondly, when not putting into the separation work, this interval makes things convenient for the strip to pass through, and upper compression roller 1 and lower arc roller 4 are all contactless belted steel, and reducing gear box 6 passes through universal joint 10 and links to each other with gear motor 11. A pair of cylinders 9 drives the swing frame 3 to rotate around the pin shaft 2, and the two working conditions of whether the separation roller is put into or not are quickly switched.
The upper press roll 1 can be a steel-based rubber lining roll, and has the functions of stabilizing the separation effect of the strip steel 7 after passing through the lower arc-shaped roll 4 and keeping the elevation of the operating line of the strip steel 7 after passing through the separation roll unchanged. The lower arc-shaped roller 4 can be a convexity-adjustable rubber lining roller, two ends of a mandrel of the lower arc-shaped roller are flat shafts, the middle part of the mandrel is bent into an arc shape, bearings are arranged on the arc-shaped part at certain intervals, and a rubber lining roller with the same radian as the mandrel is arranged on the outer ring of each bearing. The convexity presented by the arc-shaped roller and the separation effect acted on the strip steel are changed along with different swing angles of the mandrel. As shown in fig. 3, the chord height of the curved mandrel is denoted s and the maximum crown of the lower curved roll 4 depends on the chord height s and the roll face length. The lower arc-shaped roll 4 is in the prior art, the convexity of the lower arc-shaped roll 4 can be adjusted by rotating the angle of the mandrel, the convexity can be adjusted from 1 to the maximum chord height s by rotating 0 to 180 degrees, and for a specific certain arc-shaped roll, the chord height s is determined, namely the maximum convexity is fixed. The convexity is determined by considering factors such as the thickness and the material of the strip steel and the like, and is specifically adjusted according to the separation effect of the strip steel.
