Abstract
The utility model belongs to a roll changing device for the working roll of a rolling mill, in particular to a roll changing and lifting track of the working roll of the rolling mill driven by the hydraulic pressure. The roll changing and lifting track comprises a frame and roll changing tracks and is characterized in that corresponding to the parallel roll changing track position, the frame corresponding to each track is distributed with and connected with at least two hydraulic cylinders, the top surface of a cylinder rod of each hydraulic cylinder is contacted with the bottom surface of the corresponding roll changing track, the roll changing tracks are driven by the hydraulic cylinder to rise and fall simultaneously, the frame surface contacted with the top surface of the piston rod of each hydraulic cylinder is provided with a cushion pad. The roll changing and lifting track has reasonably designed structure, not only simplifies the processes for changing working rolls, shortens the roll changing time, but also increases the operating time of the rolling mill, improves the production efficiency; moreover, the roll changing and lifting track has the advantages of stable and safe operation and convenient use, etc.
Description
Technical field
The utility model belongs to the changing rig of operation roll of mill, particularly the roll change fluctuating orbit of hydraulically powered a kind of operation roll of mill.
Background technology
At present, on the continuous hot-rolling mill production line of iron and steel enterprise, production automation degree is very high at home, and the wearing and tearing of roll are also very big, and roll change is frequent, and on average each class all will carry out the replacing of working roll, to guarantee the surface quality of rolled plate.Current, for the roller that changes jobs, just at the fixed roll change track of the inner installing of the rolling-mill housing of continuous hot-rolling mill unit, two tracks that parallel put together on the frame by bolt.When needs are changed working roll, at first need the lower support roller is descended, working roll is dropped on the roll change track, the program step of its roller that changes jobs was both very loaded down with trivial details, time-consuming again.The roll change track of said fixing formula, though simple in structure, the non-cutting time that roll change is used is long, and the normal working hour of milling train is significantly reduced, thereby influences the raising of the production efficiency and the benefit of Metallurgical Enterprise.
Summary of the invention
The utility model is intended to the shortcoming and defect part that exists in above-mentioned technology, project organization is reasonable and provide not only, both reduced the program step of the roller that changes jobs, shorten roll changing time, increased the activity duration of milling train again, enhance productivity, and have smooth operation, safety, use a kind of roll change fluctuating orbit of operation roll of mill very easily.
The purpose of this utility model is to adopt following technical scheme to realize: the roll change fluctuating orbit of described operation roll of mill, comprise frame, roll change track, it is characterized in that: corresponding with parallel roll change orbital position, on the corresponding frame of each track, distribute and connect at least two hydraulic cylinders, the its corresponding roll change track of the piston rod end face bottom surface of each hydraulic cylinder touches mutually, makes the roll change track do synchronous ascending, descending campaign by Driven by Hydraulic Cylinder.
Described each hydraulic cylinder, distributing on the corresponding frame of each track connects at least two hydraulic cylinders, just installs at least four hydraulic cylinders on parallel roll change track altogether, and the quantity of its installing is relevant with the size of working roll; Each hydraulic cylinder is communicated with the hydraulic press station with pipeline respectively and joins, the valve that installing can be opened, be closed on the fluid pressure line that connection is joined.
Described support and is installed cushion pad on the frame face that each hydraulic cylinder piston rod end face touches mutually; Be used for absorbing the impulsive force that is produced when the piston rod end face contacts with track.
Owing to be to adopt hydraulic cylinder to drive the roll change track, and control the lifting of roll change track by hydraulic cylinder; When needing roll change, if open with fluid pressure line that hydraulic cylinder is connected on valve, the piston rod of these hydraulic cylinders is stretched out synchronously, the roll change track is promoted to the position of the roller that changes jobs, just can carry out the roll change work of working roll; When roll change finished, after new working roll entered rolling-mill housing, the roll change track was satisfied step decline under the gravity effect, and the piston rod of hydraulic cylinder is withdrawal just, makes the roll change track return the original place; This moment, milling train just can restart to carry out work, and whole roll change process and backing roll are irrelevant, have both shortened roll changing time widely, again smooth operation, safety.Combine the above technical measures of being taked, realize the purpose of this utility model.
Compared with prior art, the utility model not only project organization is reasonable, has both reduced the program step of the roller that changes jobs, and shortens roll changing time, has increased the activity duration of milling train again, enhances productivity, and has smooth operation, safety, uses advantages such as very convenient.
Description of drawings
The utility model has two width of cloth accompanying drawings.Wherein:
Accompanying drawing 1 is the main TV structure schematic diagram of specific embodiment of the utility model.
Accompanying drawing 2 is along the cutaway view of A-A line among Fig. 1.
Among the figure: 1, hydraulic cylinder, 2, the roll change track, 3, frame, 4, working roll, 5, cushion pad.
The specific embodiment
Fig. 1, it shown in 2 specific embodiment of the utility model, it is the roll change fluctuating orbit of installing operation roll of mill on the frame of the roughing mill in the continuous hot-rolling mill unit, its structure comprises frame 3, roll change track 2, it is characterized in that: corresponding with parallel roll change track 2 positions, on the corresponding frame 3 of each track, distribute and connect two hydraulic cylinders 1, just on parallel roll change track 2, install four hydraulic cylinders 1 altogether, the its corresponding roll change track of the piston rod end face of each hydraulic cylinder 12 bottom surfaces touch mutually, make roll change track 2 make synchronous liter by hydraulic cylinder 1 driving, motion is fallen, and with 3 of the frames of touching mutually of each hydraulic cylinder 1 piston rod end face on installing cushion pad 5.
The above; it only is the preferable specific embodiment of the present utility model; but protection domain of the present utility model is not limited thereto; all are familiar with those skilled in the art in the disclosed technical scope of the utility model, are equal to replace or change according to the technical solution of the utility model and design of the present utility model thereof all should be encompassed within the protection domain of the present utility model.
Claims (2)
1, a kind of roll change fluctuating orbit of operation roll of mill, comprise frame (3), roll change track (2), it is characterized in that: corresponding with parallel roll change track (2) position, go up connection at least two hydraulic cylinders (1) that distribute in the corresponding frame of each track (3), the its corresponding roll change track of the piston rod end face of each hydraulic cylinder (1) (2) bottom surface touches mutually, drives by hydraulic cylinder (1) to make roll change track (2) do synchronous ascending, descending campaign.
