Driven by Hydraulic Cylinder is adopted in the lifting of cold bed keep plate, by the many groups of a plurality of hydraulic cylinders controls lifting keep plates, be in respectively height, in and three kinds of states of low level, be divided into commonly used and two parts for subsequent use, to satisfy the accurately requirement of braking of different size rolling bar speed.Concrete mode is: according to mill speed spare part and part commonly used are connected some sections by clutch, the keep plate part for subsequent use that does not participate in braking is then always in a high position, the keep plate that participates in brake portion is waited at meta, when bar is transported to assigned address by inlet roller way, the major axis of Driven by Hydraulic Cylinder linkage, make keep plate drop to low level by meta synchronously, bar then slides into keep plate from roller-way and slows down; Behind keep plate on the first row steel, keep plate is climbed to meta by low level, prevents that the second row steel from entering; The first row steel slow down, in the process of braking, keep plate is risen to by meta and high-order steel is thrown in first teeth groove of cold bed static rack, and etc. pending next root bar.
The automatically control aspect of cold bed keep plate of present large-scale steel mill is comparatively stable, control program and hydraulic system are comparatively advanced, but many groups of some steel mill cold bed keep plate has asynchrony phenomenon in the debugging later stage to be occurred, this can cause the accidents such as cold bed top steel, curved steel, and accident mainly impacts the following aspects:
1. act frequently, trim designs directly causes the wearing and tearing of pressing plate pin-and-hole, bearing pin to come off;
2. computer control system PDCA abnormal circulation often occurs, cause being forced to stopping;
3. because keep plate is asynchronous, cause steel partly to unload to get off, form curved steel;
4. because the curved steel of the asynchronous formation of keep plate is extruded under the cold bed carry-over bar, cause the distortion of tooth bar and shelf;
5. because keep plate is asynchronous, cause hydraulic cylinder action vibration to strengthen, the hydraulic cylinder bolt looseness drops, and smashes pipeline and circuit;
Find that on inspection cold bed keep plate asynchrony phenomenon is because the wearing and tearing of pressing plate and bearing pin, cause the hydraulic cylinder excesssive gap that rises and falls, cause rise and fall asynchronous.In view of above situation, necessary original pressing plate is made up carried out new optimization, improves the existing design of hydraulic cylinder pressing plate.
The utility model content
Technical problem to be solved in the utility model provides a kind of Bar Cooling Bed keep plate hydraulic cylinder presser device that can improve the stability of hydraulic cylinder pressing plate.
The technical scheme that solves the problems of the technologies described above is:
A kind of Bar Cooling Bed keep plate hydraulic cylinder presser device, comprise pressing plate and bearing pin in its formation, pressing plate is welded on the shaft coupling that gets stuck, bearing pin is contained in the pin-and-hole of pressing plate, its improvements are, it has increased cutting ferrule, cutting ferrule is cylindrical sleeve, cutting ferrule is installed in the pin-and-hole of pressing plate, and bearing pin is contained in the cutting ferrule, and cutting ferrule has projection around circumference with respect to an end margin of pressing plate lateral surface, there is inside circumferential groove at edge at the pin-and-hole of the pressing plate of correspondence, the edge groove of the edge protuberance of cutting ferrule and the pin-and-hole of pressing plate is complementary, and the edge protuberance of cutting ferrule is embedded in the edge groove of pin-and-hole of pressing plate, and the lateral surface of the edge protuberance of cutting ferrule and pressing plate lateral surface flush.
Above-mentioned Bar Cooling Bed keep plate hydraulic cylinder presser device, there is respectively the groove perpendicular to the bearing pin axis at the two ends of described bearing pin, the groove inside edge is corresponding with the pressing plate outer ledge, the baffle plate lower end is embedded in the groove, screw is arranged at baffle plate top, corresponding screw is arranged on the lateral surface of pressing plate, and baffle plate is bolted on pressing plate.
Useful result of the present utility model is:
Increased cutting ferrule in the pressing plate pin-and-hole of the present utility model, bearing pin and cutting ferrule are for being slidingly matched, the cutting ferrule that increases has been avoided the wearing and tearing of pressing plate pin-and-hole, namely tear open namely after the cutting ferrule wearing and tearing and change, keep in repair very convenient, quick, also avoided after the pin-and-hole wearing and tearing of pressing plate pressing plate being sliced off from new welding, reduced maintenance time and spare part loss; The groove locking is inserted by baffle plate in the bearing pin both sides, and fixedly cutting ferrule is loosening again to get final product fixed pin shaft, has solved the problem that causes the accident because of the bearing pin loose or dislocation.The utility model has been avoided the generation of cold bed keep plate asynchrony phenomenon by above-mentioned improvement, guaranteed stability and the reliability of equipment operation, has reduced simultaneously the number of times of the curved steel of finished product.
