Description

First intermediate roll of twenty high rolling mill swing arm type supporting frame system
Technical field
The invention belongs to plate and strip rolling technology field, be specifically related to a kind of first intermediate roll of twenty high rolling mill swing arm type supporting frame system.
Background technology
In rolling metal plate and tape field, the production that integral-rack mill is little with its work roll diameter, roller system rigidity is large, percentage pass reduction is widely used in greatly stainless steel band, silicon strip and Precise Alloy band.But mill tower roll system structure is complicated, this tower roller system generally adopts the second intermediate calender rolls to carry out transmission, and first intermediate roll two ends are in vacant state, the roll gap of opening that first intermediate roll two ends cannot realize milling train normal threading without supporting operates, upper intermediate calender rolls can fall on the work rolls owing to conducting oneself with dignity, and existing technology is address this problem the normal method adopted to have two kinds.
Intermediate calender rolls two ends hang up by a kind of mode spring of hanging balancing that adopts, to balance the weight of intermediate calender rolls self, the method fore side implements convenient and reliable, but for transmission side, because such milling train adopts the second intermediate roller driven substantially, pendulum spring is often interfered with the transmission connecting shaft of the second intermediate calender rolls from space structure, the method is caused specifically to implement assembling and setting difficulty, the program is when first intermediate roll roll change in addition, each all needs manually detours to transmission side excision pendulum spring from fore side, go again after roll change to install, these bring very large inconvenience to normal production, there is potential safety hazard, cause roll changing time longer.
Another kind method, milling train front/rear door is designed with back-up block, front/rear door is closed during milling train work, thus by first intermediate roll two supports, because the method spatially limits the axially-movable of first intermediate roll, cause first intermediate roll of twenty high rolling mill these important plate form control means traversing to realize, its drawback is larger, when the method can only ensure front/rear door closed condition in addition, intermediate calender rolls is supported, when Qianmen opening, still intermediate calender rolls cannot be propped.Above two kinds of existing technical schemes cut both ways, but integrate and see, still cannot meet mill highly effective and safe, production requirement easy and simple to handle.
Summary of the invention
The object of the invention is the shortcoming overcoming above-mentioned prior art, a kind of 20 roll squeezer first intermediate roll swing arm type supporting frame systems are provided, to meet the demand when the picking-up position of intermediate calender rolls automatically can be adjusted after the adjustment of roller footpath.
For this reason, 20 roll squeezer first intermediate roll swing arm type supporting frame systems provided by the invention, by symmetrical about 20 roll squeezer center vertical, are located at two swing arm type supporting rack device compositions below two first intermediate rolls;
Described swing arm type supporting rack device comprise be located at swing arm bracket below first intermediate roll, with the fixed support of swing arm bracket by swing arm stud connection, this fixed support is located at 20 roll squeezer frame transmission sides, described fixed support is provided with swing arm oil cylinder, described swing arm oil cylinder afterbody is installed on fixed support by cylinder body hinge is hinged, swing arm oil cylinder rod end by cylinder bar connecting axle and swing arm bracket hinged.
Described cylinder body hinge one end is provided with jam plate.
Described swing arm bracket is provided with cushion block with first intermediate roll joint.
Two swing arm oil cylinders in the arm-type bracket system of described left swing and right swing arm formula bracket system are controlled by same hydraulic circuit.
Described two swing arm cylinder hydraulic circuits are provided with pressure regulator valve.
The invention has the beneficial effects as follows: when not affecting various functions such as first intermediate roll of twenty high rolling mill traversing grade, the supporting to first intermediate roll can be realized, its structure is not by the impact of the miscellaneous parts such as the second intermediate roller driven spindle, swing arm cylinder hydraulic circuit is provided with pressure regulator valve, can according to intermediate calender rolls own wt Reasonable adjustment oil cylinder strength, avoid the wearing and tearing on the excessive breaker roll surface of picking-up power, when automatically adjusting the picking-up position of intermediate calender rolls after the adjustment of roller footpath, can rocking bracket when needing roll change, intermediate calender rolls is fallen, without the need to manually going to mill drive side, manual operation is carried out to mechanism, can the roll change realizing intermediate calender rolls of quickness and high efficiency.All cylinder actions realize by the operating desk single action operation of milling train, and also chain for action feed mill program of writing can be realized automatic operation, this invention has compact conformation, highly effective and safe, advantage easy and simple to handle.
Be described in further details below in conjunction with accompanying drawing.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
In figure: 1, fixed support; 2, cylinder body hinge; 3, jam plate; 4, swing arm oil cylinder; 5, cylinder bar connecting axle; 6, swing arm hinge; 7, swing arm bracket; 8, cushion block; 9, left first intermediate roll; 10, right first intermediate roll.
Detailed description of the invention
Embodiment 1:
Present embodiments provide a kind of first intermediate roll of twenty high rolling mill swing arm type supporting frame system, by symmetrical about mill center vertical, be located at two swing arm type supporting rack device compositions below two first intermediate rolls;
Described swing arm type supporting rack device comprises the fixed support 1 be located at swing arm bracket 7 below first intermediate roll, be connected by swing arm hinge 6 with swing arm bracket 7, this fixed support 1 is located at 20 roll squeezer frame transmission sides, described fixed support 1 is provided with swing arm oil cylinder 4, described swing arm oil cylinder 4 afterbody is installed on fixed support 1 by cylinder body hinge 2 is hinged, and swing arm oil cylinder 4 rod end is hinged by cylinder bar connecting axle 5 and swing arm bracket 7.
