Description
Technical field
The present invention relates to continuous casting cast steel technical field, more particularly to a kind of device for eliminating segment roll gap structure interval.
Background technology
In continuous casting, the precision of continuous casting machine roll-gap is extremely important, is the deciding factor for influencing product quality.Continuous casting
The roll gap of machine is made of the roll gap of several fan-shaped sections, and therefore, segment roll gap must first be controlled by controlling continuous casting machine roll-gap,
And the structure interval of each segment roll gap includes gap connecting rod and the gap of axis pin and axis pin with being connected yoke；If
Conticaster is unloaded and two kinds of operating modes of production under, if the roll gap of this structure interval differs greatly, sector can be directly influenced
Section roll gap precision, ultimately results in serious slab quality problem.
The content of the invention
For overcome the deficiencies in the prior art, the present invention provides a kind of device for eliminating segment roll gap structure interval, uses
In eliminating above-mentioned segment roll gap Mechanism Clearance, roll gap precision is improved.
To achieve these goals, the present invention is achieved through the following technical solutions：
A kind of device for eliminating segment roll gap structure interval, including upper surface are equipped with the wedge shaped support plate 16 of inclined-plane A,
The top of wedge shaped support plate 16 is equipped with wedge clamp 13, and the angle of 13 lower surface of wedge clamp is adapted with inclined-plane A, to keep
13 upper surface of wedge clamp is in horizontal, and cover board 18 is equipped with above wedge clamp 13, and the top of cover board 18 is equipped with spring 12,
The top of spring 12 sets backplate 11, and the backplate 11 carries the groove being adapted with spring 12, and backplate 11 and the cover board of lower section
18 and wedge clamp 13 leave gap, arc contact plate 10 is also embedded with above backplate 11；
The wedge shaped end lateral surface of the wedge clamp 13 is equipped with the baffle 20 that wedge clamp 13 can be promoted to move, gear
Plate 20 is connected to 16 one end of wedge shaped support plate by bolt 14.
The backplate 11 and cover board 18 are connected by stud 19 with wedge clamp 13, and the nut and backplate of the stud 19
Gap is left between 11.
The inclined-plane A angles of the wedge shaped support plate 16 are less than the critical angle of material.
The both ends in wedge clamp 13 along the wedge-shaped direction are equipped with the protrusion for preventing that backplate 11 from breakking away.
The spring 12 is multiple.
Beneficial effects of the present invention：
The present invention by setting the clapboard that is adapted of two bevel angles come the working method of regulating device oneself height,
Horizontal direction force is smoothly converted to vertical stress, adjusting process is simple, result is accurate；Due in device force transferring part
Equipped with spring, when job state or stress change when external condition, the roll gap that may make to have eliminated is opened again
Open, if using traditional rigid contact mode, unbalance stress can occur, respond the problems such as slow, and the present apparatus uses bullet
The mode of spring power transmission, when stress change occurs, the spring of compressive state can discharge part elastic force, so as to can keep stress all the time
Dynamic equilibrium, maintains equipment even running.

Embodiment
The present invention is described in detail with reference to the accompanying drawings.
As shown in Fig. 2 Fig. 3：The wedge shaped support plate 16 of inclined-plane A is equipped with including upper surface, is equipped with above wedge shaped support plate 16
Wedge clamp 13, the angle of 13 lower surface of wedge clamp are adapted with inclined-plane A, to keep 13 upper surface of wedge clamp to be in
It is horizontal, the baffle 20 that wedge clamp 13 can be promoted to move, baffle 20 are equipped with the wedge shaped end lateral surface of wedge clamp 13
16 one end of wedge shaped support plate is connected to by bolt 14；Cover board 18 is equipped with above wedge clamp 13, the top of cover board 18 is equipped with more
A spring 12, above spring 12 set backplate 11, the backplate 11 carry with spring 12 be adapted groove, and backplate 11 with
The cover board 18 and wedge clamp 13 of lower section leave gap；The backplate 11 and cover board 18 pass through stud 19 and 13 phase of wedge clamp
Even, and gap is left between the nut of the stud 19 and backplate 11；The wedge clamp 13 is all provided with along the both ends in wedge-shaped direction
There is the protrusion for preventing that backplate 11 from breakking away, arc contact plate 10 is also embedded with above backplate 11.
The spring 12 is disc spring.
The operation principle of the present invention：
As shown in Fig. 1 Fig. 2：Fig. 1 is by hydraulic cylinder 1, upper frame 1, connection yoke 3, axis pin 4, connecting rod 5, body side frame 7, lower frame
Frame 7, roller 8 etc. form.
The present apparatus is placed between body side frame 7 and connection yoke 3 first, then rotating bolt 14, promotes wedge clamp
13 do relative motion to 16 direction of wedge shaped support plate, and in the process, the position meeting occurred level of wedge clamp 13 moves up, and then
Cover board 18 is driven to move up, cover board 18 compresses spring 12 and produces upward pretightning force, and the power is through backplate 11 and arc contact plate
10 transmission, is ultimately applied on connection yoke 3, moves up connection yoke 3, thus eliminating the need connecting rod 5 and axis pin 4
The gap of gap and axis pin 4 with being connected yoke 3, makes conticaster roll gap under unloaded two kinds of operating modes with production consistent.
Equipment, when job state or stress change when external condition, may make to have disappeared during operation
The roll gap removed opens again, if using traditional rigid contact mode, unbalance stress can occur, respond the problems such as slow,
And the present apparatus is by the way of 12 power transmission of spring, when stress change occurs, the spring 12 of compressive state can discharge part elastic force,
So as to keep, by force homeostasis, maintaining equipment even running all the time.
Left-handed rotation stud 14 is only needed when needing and discharging pretightning force.The specification and quantity of spring 12 are according to actual need
Pretightning force and the gap size selection wanted.
