Description
Technical field
The present invention relates to a kind of pedestal device of four or six roller exchange mills, belong to the rolling equipment technology.
Background technology
Four or six roller exchange mills of the present invention are a kind of simultaneously possess sheet metal four-high mill and six-high cluster mill function and that can exchange at the machine practical function or strip-rolling equipments.
Described four or six roller exchange mills, need to realize that when hot rolling four roller the work roll shaft moves, and in the middle of realizing when cold rolling six roller, roll shaft moves, and because four-high mill is that working roll drives, and six-high cluster mill is the intermediate calender rolls driving, thereby existing fixed pedestal, just can not meet the job requirement of four or six roller exchange mills.
For this reason, research and develop a kind of pedestal device that can adapt to four or six roller exchange mill job requirements, just become the key subject of applying four or six roller exchange mills.
Summary of the invention
The present invention aims to provide a kind of pedestal device of four or six roller exchange mills, to meet the driving requirement of four or six roller exchange mill function conversions, for applying four or six roller exchange mills, provides technical support.
The present invention realizes the technical though of its purpose, be the fixed version in prior art pedestal position, be improved to the version that the pedestal position can change, by the Driven by Hydraulic Cylinder assembly, change upper and lower 2 the residing relative positions of pedestal of every side, meet the requirement of two kinds of functions of described four or six roller exchange mill to different driving object (working roll and intermediate calender rolls), realize that respectively the working roll of described four or six roller exchange mills drives and the intermediate calender rolls driving.And described pedestal device of the present invention, be on the basis of prior art pedestal device realize by innovating, convenient to reach old mill type modification, the easy requirement of new architecture manufacture.
Based on above-mentioned technical though, the present invention realizes that the technical scheme of its purpose is:
A kind of pedestal device of four or six roller exchange mills comprises:
One pedestal reciprocating mechanism; Described pedestal reciprocating mechanism, comprise the guide plate seat and the guide plate that are fixedly connected with the rolling-mill housing driving side, described guide plate by and guide plate seat between set rail plate secondary and can slide along the frame above-below direction;
One driving universal joint supporting mechanism; Described supporting mechanism, comprise that holding bar and holding bar withhold member; The holding bar by 2 arranged apart and holding bar that be fixedly connected with guide plate withhold member, and can laterally slide along guide plate; The inner of described holding bar has the concave surface matched with the universal joint surface with described driving;
The described pedestal be comprised of with the universal joint supporting mechanism pedestal reciprocating mechanism and driving has 4,4 pedestals each side have 2 at milling train driving side framework window, and 2 pedestals of every side are arranged apart up and down, and left and right sides pedestal is arranged symmetrically with; Between the holding bar of upper and lower 2 pedestals of every side, be connected with along the vertical direction connecting rod; Also comprise transverse hydraulic cylinder driven unit, described connecting rod is connected with the piston rod of Driven by Hydraulic Cylinder assembly, and transverse hydraulic cylinder driven unit is fixedly connected with guide plate; Drive horizontal oil hydraulic cylinder driven unit, described left and right holding bar can be involutory or separately, its innovative point is:
Also comprise the pedestal position adjusting mechanism; Described pedestal position adjusting mechanism, comprise the vertical Driven by Hydraulic Cylinder assembly in the guide plate be located in the included guide plate of 2 pedestals of each side, and the piston rod of described vertical Driven by Hydraulic Cylinder assembly is connected with the guide plate of another pedestal; Drive vertical Driven by Hydraulic Cylinder assembly, can make the distance between upper and lower 2 pedestals of every side draw close or separate.
By above given purport technical scheme of the present invention, can be understood, existence due to the pedestal position adjusting mechanism, can be under the driving of vertical Driven by Hydraulic Cylinder assembly, realize separating or drawing close of upper and lower 2 pedestals of every side, and having separated lucky adaptation intermediate calender rolls drives, having drawn close lucky adaptation working roll drives, four or six roller exchange mill two kinds of functions have been met respectively for the job requirement of two kinds of type of drive, and of the present invention simple in structure, its space of occupying is less, can not produce and interfere adjacent component, thereby realize purpose of the present invention.
Because the pedestal of pedestal device of the present invention, so that the framework window center line is left and right, be arranged symmetrically with, and the holding bar of left and right pedestal separately or involutory, synchronization action preferably, the holding that is used for that 2 holding bars after involutory with effective guarantee are formed drives with the heart among the holding hole of universal joint, can be consistent with the axis of working roll or intermediate calender rolls, for this reason, the present invention advocates, described transverse hydraulic cylinder driven unit and vertical Driven by Hydraulic Cylinder assembly, all realize the collective synchronization SERVO CONTROL by milling train master control device.
And described SERVO CONTROL, by the PLC Programmable Logic Controller, by angular displacement sensor and servo-driver, the servomotor that is present in the motor-driven valve on described transverse hydraulic cylinder driven unit and vertical Driven by Hydraulic Cylinder component pressure fluid media (medium) pipeline is controlled.
Guide plate for the reciprocating mechanism included to the present invention, likely can be from the consideration of guide plate seat lower end slippage correct location of upper and lower supporter pedestal out and under operating mode, the present invention also advocates, also comprises block, and described block is laid in the bead position, bottom of guide plate seat.Due to the existence of block, can effectively avoid the improper of guide plate position.Although due to the existence of vertical Driven by Hydraulic Cylinder assembly that the pedestal position adjusting mechanism is arranged between the upper and lower supporter pedestal, the possibility that the too much displacement of described guide plate even produces slippage is very little, and in view of the consideration of safety and guide plate fixation, setting up block has positive effect.
Consider the holding bar of 2 pedestals that are symmetrically arranged, likely there is the asymmetric of present position, cause by 2 of left and right holding bar and draw close and involutoryly formed be used for holding and drive the holding hole with universal joint, with working roll or intermediate calender rolls decentraction (although driving the line shaft of use that universal joint is arranged), and affect the transmission of driven power, the present invention also advocates being connected of described holding bar and connecting rod, is that the slotted hole set by the holding bar is connected with connecting rod via connector.So just, can pine connector, the set slotted hole by the holding bar, adjust to symmetrical position by 2 of left and right holding bar.
Here should be noted that, in purport technical scheme of the present invention, described vertical Driven by Hydraulic Cylinder assembly, can be also single-row assembly (being that described vertical hydraulic pressure cylinder assembly is not arranged on it in guide plate), and its oil cylinder is connected with a guide plate, its piston rod is connected with another guide plate.Described single-row Driven by Hydraulic Cylinder assembly, the Existential Space condition not in its installation position, and be difficult to concrete enforcement.
After technique scheme is implemented, it is simple in structure that the present invention has, and old mill type modification is convenient, and new architecture is manufactured simple and easy, can meet four or six roller exchange mills, and the characteristics such as conversion of the power drive mode when its exchange function, be very obvious.
