Abstract
The invention discloses a static pressure central frame of a heavy-duty mill roll. At least two static pressure tiles inserted into a 'U'-shaped slot of a tilting fillet of the static pressure central frame are symmetrical along the axial vertical central surfaces of the tilting fillet of the static pressure central frame. A concave static pressure oil groove is arranged on a truncated conical cambered surface at the upper ends of the static pressure tiles. A trapezoid space is formed between the lower end surfaces of the static pressure tiles and the upper end surface of the tilting fillet of the static pressure central frame. A wedge block can be just inserted into the trapezoid space. The depth of the wedge block in the trapezoid space in the inclined direction can be adjusted. Intersecting lines of the axial central surfaces of the static pressure tiles are collinear. The side wall of a pressing plate fixedly arranged on the tilting fillet of the static pressure central frame is tightly stuck with the back side walls of the static pressure tiles. A penetrating opening in the pressing plate is matched with the position of an oil supply port communicated with the static pressure oil groove. An oil cylinder barrel of a stop damping mechanism is fixedly located on the upper side surface of the tilting fillet of the static pressure central frame. A piston rod of an oil cylinder is fixedly connected with the lower end of a damping block. The piston rod of the oil cylinder can drive the damping block to move along the vertical direction. The static pressure central frame of the heavy-duty mill roll realizes quick starting and stopping of grinding of the mill roll.
Description
Technical field
The present invention relates to a kind of auxiliary body of roll grinder, particularly a kind of heavy roll static pressure centre frame.
Background technology
The bearing capacity of domestic CNC roll grinder manufacturing enterprise static pressure centre frame is 150 tons, realize that weight reaches 300 tons superduty roll dressing processing and mainly need solve two problems:
1. not causing under the at all impaired prerequisite of roll seating surface (filmatic bearing face), realize the supporting of heavy rolls;
2. after support problem solved, the startup that solves heavy rolls reached and only stops.
Because roll weight is big, the moment of inertia is also just quite big, be difficult to realize the quick startup of roll, after the startup, if roll any problem occurs in grinding process or grinding is through with, have to be difficult to realize only stopping of roll, in grinding process, will waste a large amount of time like this and realize start and stop, also can be because of stopping to cause device damage fast.
Summary of the invention
In order to remedy above deficiency, the invention provides a kind of heavy roll static pressure centre frame, this heavy type roll static pressure centre frame can be realized the rapid starting/stopping of heavy roll in the heavy roll of stable support.
