Description
Technical field
A kind of coiler bottom working roll elevating mechanism, belongs to coiler technical field.
Background technology
The coiler that current activity in production uses, coiler by upper and lower, the rotary motion of side roller, elevating movement generation change in location, realize to various irregular section bar, tubing bend work.And lower roll elevating movement majority adopts hydraulic jack, the lifting list of tradition lower roll adopts oil cylinder lifting to transmit power (see figure 1), this alone oil cylinder transmits power and there is following defect: when coiler starts coil pipe, working roll all needs to stablize, accurate radial load and moment of torsion, and hydraulic system is more responsive to temperature, can not strict guarantee stable drive ratio, also cannot the section bar rolling out be adjusted; Secondly, when rolling large-scale workpiece, needing the radial load of working roll and moment of torsion to meet and rolling requirement, if lower roll uses alone oil cylinder to support, the size of oil cylinder used is just larger, needs the size by strengthening oil cylinder to meet, so shared space is just larger, and manufacturing cost is also higher.
Utility model content
Technical problem to be solved in the utility model be to provide a kind of take up room little, gearratio is stablized, meet and roll the coiler elevating mechanism of large-scale workpiece.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts: a kind of coiler bottom working roll elevating mechanism, comprise cotter mechanism and oil cylinder, described cotter mechanism comprises and is horizontally disposed first voussoir and the second voussoir, wherein the first voussoir is arranged on the below of bottom working roll and is connected with bottom working roll bearing body, second voussoir is close to and is arranged on below the first voussoir, and the second voussoir and the first voussoir are positioned opposite, described oil cylinder and the second voussoir are arranged in the same horizontal line, and the piston rod of oil cylinder is connected with one end of the second voussoir.
Described first voussoir and the second voussoir cross section are triangle.
Described first voussoir and the second voussoir cross section are trapezoidal.
Compared to the prior art the utility model has following beneficial effect.
One, substitute traditional alone oil cylinder with this device to support, realize machine driving and hydraulic drive combines, large thrust is provided by oil cylinder, cotter mechanism provides stable radial load to realize stable and accurate radial load and moment of torsion, thus ensure that rolling out workpiece meets uniformity and required precision, namely ensure that constant gearratio, stable working, reliability are high.
Two, when this device of needs rolls larger workpiece, the lifting of bottom working roll is realized by the relative sliding of the first voussoir and the second voussoir in cotter mechanism, namely required radial load and moment of torsion can be ensured when not taking greater room, realization rolls large-scale workpiece, expand the scope of application of coiler, also effectively reduce the manufacturing cost of coiler complete machine.
Accompanying drawing explanation
Fig. 1 is the structural representation of traditional bottom working roll elevating mechanism.
Fig. 2 is the structural representation of this device.
Fig. 3 is the side view of Fig. 2.
In figure, 1 is bottom working roll bearing body, and 2 is bottom working roll, and 3 is oil cylinder, and 4 is the first voussoir, and 5 is the second voussoir.
