Description
One, technical field
The utility model relates to metal shaping equipment, particularly a kind of group drive system for metal axial continuous mill.
Two, background technology
As everyone knows, the metal axial continuous rolling process will be realized that stable state is rolling and must equate to be prerequisite with the second flow amount of rolled piece by each rolling mill roll.For satisfying this condition, present metal axial tandem mill generally adopts computer controlled automatic and high accuracy collective transmission dual mode.Adopt computer controlled automatic, to on every rolling mill, install low and frequency conversion control device additional, install the kink maker additional between per two rolling mills, to carry out repeatedly careful parametric measurement earlier to the relative stations of technological equipment, then according to the laid down by rolling procedure of measuring, set up Mathematical Modeling, the exploitation corresponding software disposes corresponding P-C system to equipment.This control mode structure and technical sophistication are invested hugely, and because of all there is certain inertia in the power motor of each sortie milling train, response speed is limited, and control accuracy is limited, can not eliminate the generation that heap draws accident fully.Adopt the transmission of high accuracy collective, be representative with the root milling train that rubs that generally uses at present, very high though mill speed is fast to the required precision of the precision of milling train and rolled piece, milling train manufacturing expense costliness, maintenance period is long, and whole rolling is only limited to wire production.
For overcoming above-mentioned technological deficiency, publication number is that the Chinese utility application specification of CN1279138 has disclosed a kind of group drive system for metal axial continuous mill.It is power that this system adopts an alternating current generator, is made of parts such as the symmetrical expression cone planetary gear differential mechanism that equates with the mill stand sub-quantity and supporting with it reducing gear and mono-directional overrun clutch.This transmission adopted symmetrical expression cone planetary gear differential mechanism and assembly thereof carry out collective's transmission and control to the milling train driven roller, though can realize the second flow amount mates automatically, satisfy the rolling condition that the second flow amount equates, and have simple in structure, the advantage that manufacturing expense is low, but this transmission system is also because of existing following shortcoming to make it be difficult to promote the use of: the one, and many symmetrical expression cone planetary gear differential mechanisms of this transmission system adopt a plain shaft to connect each other, make it planar can only become two column distributions, this just makes the tandem rolling unit of this system of employing can only be installed in its top, for satisfying the transmission requirement, the length of rolling mill roll must equate with the span of two row symmetrical expression cone planetary gear differential mechanisms, make roll length longer, can only roll wide strip, this has just limited the range of application of this transmission system; Simultaneously longer because of connecting axle, also be difficult to the required precision of the system that guarantees.The 2nd, this transmission system does not have to consider to have the tandem mill of crimping device, and the crimping device of the tandem mill of transmission simultaneously must set up the crimping device transmission mechanism for the tandem mill that has crimping device.The 3rd, this transmission system is a power with a motor, and power is limited, does not consider how system improves power output problem when power can not satisfy the milling train requirement.The 4th, this transmission system is for realizing milling train rolled piece exit function, and the ad hoc rolled piece drawing-out mechanism that is made of cone gear reducer, worm reduction gear and two-stage involute cylindrical gear decelerator has increased the complexity of system architecture.The 5th, the reductor and the differential mechanism that are complementary with each symmetrical expression cone planetary gear differential mechanism in this transmission system are made of one, and parts are difficult for standardization, the manufacturing cost height.
Three, utility model content
The purpose of this utility model is improved at the shortcoming of above-mentioned tandem mill collective transmission system, a kind of applied range, the tandem mill of transmission simultaneously crimping device are provided, can increase power with the multiple electric motors combination, simple in structure and parts are easy to standardized group drive system for metal axial continuous mill.
The group drive system for metal axial continuous mill that the utility model provides is made up of actuating unit and transmission mechanism, and its actuating unit is a kind of in following three kinds:
1) end by an alternating current generator and universal drive shaft joins;
2) joined with two semiaxis of symmetrical expression cone planetary gear differential mechanism respectively by two alternating current generators, the driving gear shaft of symmetrical expression cone planetary gear differential mechanism and an end of universal drive shaft join;
3) four alternating current generators are divided into two groups, every group two, two semiaxis with symmetrical expression cone planetary gear differential mechanism join respectively, the driving gear shaft of symmetrical expression cone planetary gear differential mechanism joins by two semiaxis of universal drive shaft and another symmetrical expression cone planetary gear differential mechanism respectively, and the driving gear shaft of this symmetrical expression cone planetary gear differential mechanism and an end of another universal drive shaft join;
