Abstract
The utility model relates to a roll gap adjusting device in a hot continuous rolling rougher area vertical miller, in particular to the vertical miller which can realize plate blank width automatic control and plate blank head and tail shape control (short stroke control). The vertical miller is composed of a hydraulic cylinder and a hydraulic cylinder balancing device, wherein the hydraulic cylinder and the hydraulic cylinder balancing device are arranged on a hydraulic cylinder bracket, and a side compression motor rotatably drives a side compression speed reducer and a side compression feed screw 8 to rotate. The purpose of the utility model is to provide the vertical miller which reduces waste, improves the material obtaining rate, lowers the cost, and realizes the plate blank width automatic control and the plate blank head and tail shape control (short stroke control).
Description
Technical field
Roll gap adjusting device in the rougher of hot strip mill described in the utility model district vertical miller, be a kind ofly realize that width of plate slab is controlled automatically, the vertical miller of slab Head and Tail Shape control (short stroke control).
Background technology
Along with rapid development of national economy, industry-by-industry is increasing to the demand of hot-strip, and is also more and more higher to the requirement of the product quality of hot-strip.Simultaneously, the market competition of hot strip steel is also fierce day by day, this just proposes higher requirement qualitatively to the width of hot strip steel product, obtain minimum waste, the highest volume ratio in links such as crop, back-end crop and side cut, makes cost reduce, improve enterprise competitiveness.The version complexity that exists in the same category of device of home and abroad, hydraulic jack safeguarded that inconvenient, side pressure leading screw was long to processing problem such as make troubles in the past.Width of plate slab is controlled automatically so design a kind of novel realizing, the vertical miller of slab Head and Tail Shape control (short stroke control) is very necessary.
Summary of the invention
In view of existing problem in the prior art, the purpose of this utility model provides and a kind ofly cuts the waste, improves volume ratio, reduces cost, realizes that width of plate slab is controlled automatically, the vertical miller of slab Head and Tail Shape control (short stroke control).
Technical solution of the present utility model is achieved in that
Roll gap adjusting device in a kind of rougher of hot strip mill district vertical miller comprises roll, frame and side pressure motor, it is characterized in that also comprising hydraulic jack, hydraulic jack carriage, side pressure leading screw, side pressure nut, side pressure reductor and bascule; Described side pressure motor and side pressure reductor link, the worm and gear transmission is arranged in the side pressure reductor, worm gear set wherein is contained on the side pressure leading screw, sleeved and laterally-pressed nut on the side pressure leading screw, the side pressure nut is packed on the frame, the side pressure leading screw can spinning in and out in the side pressure nut, drive hydraulic jack and the roll of fixedlying connected with it moves axially.
Described bascule is contained in the left and right side of frame respectively, and be connected with the hydraulic jack carriage by the through hole on the frame, two hydraulic jacks all are housed on each hydraulic jack carriage, and the two ends of hydraulic jack all are connected with an end of corresponding roll neck and side pressure leading screw.
Compared with prior art, advantage of the present utility model has been to solve the version complexity, the hydraulic jack that exist in the home and abroad same category of device in the past and has safeguarded that inconvenient, silk pressing bar is long to processing problem such as make troubles.Thereby provide and reduced waste, improve volume ratio, reduce cost, and be to have realized that width of plate slab is controlled automatically, the function of slab Head and Tail Shape control.
Roll gap adjusting device described in the utility model, its operation principle are in the rolling intermittent phase, for adjusting two opening degrees between the roll, thereby are promoted by side pressure leading screw, side pressure nut by side pressure driven by motor side pressure reductor that AWC cylinder and roll realize.Side pressure leading screw one end fixation side pressing system is used for adjusting roll, and it has the mill stiffness height, strip quality height, the advantage that roll change is time saving and energy saving.The effect of bascule is to eliminate roll gap, adjusts the gap between the part, guarantees the stability in the operation of rolling.The AWC cylinder is to be used in the operation of rolling slab being carried out width control and slab Head and Tail Shape control (short stroke control) automatically.The push-and-pull by the side pressure leading screw on the AWC bracket cylinder of AWC cylinder is implemented in the walking in the frame, and this design feature is that taking out with packing into than the vertical miller of other form concerning the AWC cylinder is very easily.When changing roll, roll moves to the roll change position by bascule, has shortened the length of side pressure leading screw so greatly, has made things convenient for the processing and the heat treatment of side pressure leading screw.
Description of drawings
The utility model has two accompanying drawings, wherein:
Accompanying drawing 1 is the fundamental diagram of the roll gap adjusting device in the rougher of hot strip mill district vertical miller.
Accompanying drawing 2 is partial enlarged drawings of accompanying drawing 1.
Among the figure: 1, driving motor, 2, the main transmission reductor, 3, connect a lift cylinders, 4, main transmission spindle, 5, hydraulic jack, 6, the hydraulic jack carriage, 7, roll, 8, side pressure leading screw, 9, the side pressure nut, 10, frame, 11, side pressure reductor, 12, side pressure motor, 13, bascule, 14, support.
The specific embodiment
As shown in the figure, the utility model roll gap adjusting device is applied on the self-bearing type vertical miller, its operation principle is in the rolling intermittent phase, drive 11 rotations of side pressure reductor by 12 rotations of side pressure motor, by the effect of turbine and worm, drive 8 rotations of side pressure leading screw and make hydraulic jack 5, roll 7 produce and move axially, then because of hydraulic jack 5 is fixed on the hydraulic jack carriage 6, so realized the walking of hydraulic jack 5 in frame 10, thereby reached the purpose of adjusting the opening degree between two rolls 7.Wherein the effect of bascule 13 is to eliminate the gap between the part in the roll gap adjustment, guarantees the stability in the operation of rolling, and hydraulic jack 5 is to be used in the operation of rolling slab being carried out width control and the control of slab Head and Tail Shape automatically.Hydraulic jack 5 push-and-pull by side pressure leading screw 8 on hydraulic jack carriage 6 is implemented in the walking in the frame 10, and it is very easily that this design feature is taken out with packing into than the vertical miller of other form concerning hydraulic jack 5.When changing roll, roll moves to the roll change position by bascule 13, has shortened the length of side pressure leading screw 8 so greatly, has made things convenient for the processing and the heat treatment of side pressure leading screw 8.This method of adjustment has mill stiffness height, strip quality height, the time saving and energy saving advantage of roll change.
