This existing pressure head mounting structure.When needs dismounting and change pressure head, pressure head and pressure head are installed the pressured plate of end plate and are articulated in screw mandrel and articulate on the round platform, like this can so that work high above the ground pressure head is changed, can be very convenient quick so that change pressure head.Simultaneously, in operate as normal steel rolling, adjust the upper support roller by the lifting of main equalizer bar, the interlock of upper support roller when keeping screw mandrel to move upward, make to articulate on pressing plate and the screw mandrel to have the gap between the round platform all the time, so there is not frictional force between pressing plate and screw mandrel, pressure head can not spin.
But the four-high reversing mill of this structure is found when work, usually can not catch up with owing to the electric interlock reaction appears in reasons such as electrical part is aging, the interlock hysteresis occurs.Be that screw mandrel is depressed the back when lifting, main equalizer bar does not catch up with the rotation of screw mandrel, and the screw mandrel lower end will break away from pressure head.So just cause pressing plate and screw mandrel to articulate round platform and contact and produce friction, and then cause that pressure head spins, destroy various fluid pressure lines and the dust cover arranged on the pressure head.Make to produce and pause, need the long period to repair.
The utility model content
At the deficiencies in the prior art, technical problem to be solved in the utility model is, after how a kind of installation is provided, can either conveniently overhaul the replacing pressure head, can when taking place, the electric interlock hysteresis avoid device damage again, the normal operation of assurance equipment prolongs the four-high reversing mill pressure head installation pressure plate structure of service life of equipment.
In order to solve the problems of the technologies described above, adopted following technical scheme in the utility model:
A kind of four-high reversing mill pressure head is installed and is used pressure plate structure, described pressing plate integral body is annular slab, it is characterized in that, described pressing plate medial surface place circular diameter is greater than articulating the round platform outside diameter, the pressing plate lower surface has been disposed radially a chute, is provided with one in the chute and articulates locating hole.
When the utility model is installed and used, pressing plate adopts bolting to install on the end plate to pressure head, because pressing plate medial surface place circular diameter is greater than articulating the round platform outside diameter, so pressing plate with articulate round platform and do not have intersection in short transverse, in the screw mandrel uphill process when the electric interlock hysteresis occurring, pressing plate can not contact with articulating round platform yet, can not produce the pressure head accident of spinning and cause equipment to be damaged, and has guaranteed smooth and easy the carrying out of work.When needs overhaul pressure head, need an auxiliary slide block and a fastening screw, slide block is provided with the slide block locating hole, and described slide block locating hole articulates distance between the round platform side to distance between the slide block inner side edge to the screw mandrel greater than articulating locating hole.Like this, be inserted into slide block in the chute and to adopt fastening screw to insert fixing, because the slide block locating hole articulates distance between the round platform side to distance between the slide block inner side edge to the screw mandrel greater than articulating locating hole, be positioned at the part that articulates the round platform top so have one after slide block is positioned, make pressure head to be articulated in articulating on the round platform of screw mandrel by slide block, and then can overhaul easily.
In sum, the utility model can either conveniently overhaul the replacing pressure head, can avoid device damage when the electric interlock hysteresis takes place again, guarantees the normal operation of equipment, prolongs service life of equipment.Simultaneously the utility model can directly be transformed enforcement at existing equipment, also have simple in structure, advantage such as it is convenient to implement, and implementation cost is cheap.
