Abstract
The utility model relates to a steel sheet thickness screwdown gear, worm gear transmission, lifting screw and pressure head more than motor, casing, two -stage, the motor is connected on the casing, and the motor output shaft is worm gear transmission more than the coupling joint two -stage, and the worm gear transmission connection drives the lifting screw of lift by it more than the two -stage, and the pressure head is connected to the lifting screw bottom. The motor drives little worm, little worm wheel, worm and big worm wheel transmission in proper order greatly through the shaft coupling, and big worm wheel passes through spline transmission lifting screw, drives the pressure head from this and goes up and down to adjust steel sheet press forming thickness. In the use, the above auto -lock worm gear transmission of two -stage can effectively avoid the molten steel to spring up the return difference that causes, ensures the gauge control precision, and the deviation is little, is favorable to ensureing product quality and manufacturing cost.
Description
Technical field
The utility model relates to a kind of Plate Production frock, is that a kind of Plate Production thickness regulates screwdown gear specifically.
Background technology
In steel plate cast is produced, because difference specifies that the thickness of steel plate is different, its compressing thickness needs control and regulation, the worm-gear speed reducer that tradition adopts drives the control of the compressing pressure head pressure of lift adjustment thickness, but the high speed due to molten steel springs up and the return difference of worm and gear easily causes pressure head rising to make a concession, steel plate thickness deviation is large, and thickness control accuracy is low.
Summary of the invention
For the deficiency that steel plate thickness control accuracy of the prior art is low, the utility model provides that a kind of structure is simple, stable transmission, effectively can guarantee thickness control accuracy, avoid the steel plate thickness screwdown gear that steel plate thickness deviation is large.
The technical solution adopted in the utility model is: a kind of steel plate thickness screwdown gear, comprise motor, housing, the above worm gearing of two-stage, lifting screw and pressure head, motor is connected on housing, motor output shaft connects the above worm gearing of two-stage through shaft coupling, the above worm gearing of two-stage connects the lifting screw being driven lifting by it, connects pressure head bottom lifting screw.
Further, described worm gearing is self-locking worm gear worm gearing.
Again further, the first order worm gearing of the above worm gearing of described two-stage comprises small gear and small worm, small worm connects motor output shaft through shaft coupling, small worm engaged transmission small gear, small gear connects the large worm screw of second level worm gearing with axle key, the large worm gear of the large worm engaging transmission second level worm gearing of second level worm gearing, the large worm gear endoporus spline joint lifting screw of second level worm gearing.
Adopt technique scheme, the beneficial effects of the utility model are: motor drives small worm, small gear, large worm screw and large worm gear transmission successively through shaft coupling, large worm gear is elevated by spline drived lifting screw, is with the compressing thickness of dynamic head lift adjustment steel plate thus.In use, self-locking worm gear worm gearing more than two-stage, the return difference effectively avoiding molten steel to spring up causing, guarantee thickness control accuracy, deviation is little, is conducive to guaranteeing product quality and production cost.
