Description
Technical field
The utility model relates to looper between a kind of hot-rolling finishing mill, is specially looper between a kind of finishing mill.
Background technology
Between hot-rolling finishing mill, a good looper should have following basic function and requirement: must have response fast, after last support nipped by band steel, loop back roll should rise rapidly, form kink, make the rolling under Minimal Tension of band steel, when before a frame support after magnetic tape trailer leaves, the location variation of loop back roll should send deviation correcting signal to main transmission immediately by automatic control system, thus the change of maintainance set amount is little; When cover amount changes within the specific limits, the maintenance that the tension force of band suffered by steel should be similar to is constant; Looper should be able to ensure the kink amount of the band steel storage certain length between two planishing stands, the second flow deviation that absorption band steel toe tail rolldown speed deviation causes; Looper can at inner conversion tension force in a big way, to adapt to different strip steel specification; The inside of looper should reduce friction, to keep identical tension; The gap, each portion of looper should be minimum, to avoid the signal that sends inaccurate.
Develop a set of stable working based on above function and requirement, highly sensitive, that constant tension, adjustable range are large, mechanism is simple, safe and reliable looper is necessary.
Summary of the invention
For the problems referred to above, the technical problems to be solved in the utility model is to provide looper between a kind of finishing mill.
Looper between a kind of finishing mill of the present utility model, comprise mill housing, cylinder pedestal, hydraulic cylinder, loop back roll swing arm assembly and loop back roll assembly, described cylinder pedestal is arranged on mill housing, described hydraulic cylinder lower end is connected with cylinder pedestal, described hydraulic cylinder upper end is connected with loop back roll swing arm assembly, described loop back roll assembly is arranged on loop back roll swing arm assembly, described loop back roll assembly and loop back roll swing arm assembly are all fixed on above mill housing, are provided with pressure sensor and displacement transducer in described hydraulic cylinder.
Preferably, described hydraulic cylinder lower end is connected with cylinder pedestal by bearing pin.
The utility model beneficial effect: the utility model is by Driven by Hydraulic Cylinder loop back roll swing arm assembly and drive loop back roll assembly to swing, strap tension is detected by the pressure sensor of hydraulic cylinder inside, feed back to Hydrauservo System, change the stroke of hydraulic cylinder, thus change the position of loop back roll assembly.In addition, displacement transducer in hydraulic cylinder can detect the pendulum angle of loop back roll, and this value is fed back to main mill, can in real time, steadily, fast, accurately, reliably, the position of automatically on-line control loop back roll, thus meet the requirement of hot continuous rolling process to looper, and the operating efficiency that can improve, improve equipment easy applied performance and automaticity, and structure is reliable, and security is good.
accompanying drawing illustrates:
For ease of illustrating, the utility model is described in detail by following concrete enforcement and accompanying drawing.
Fig. 1 is this utility structure schematic diagram.
Fig. 2 is the structure sectional view of A-A section hydraulic cylinder and cylinder pedestal junction in Fig. 1.
In figure: 1-mill housing; 2-cylinder pedestal; 3-hydraulic cylinder; 4-loop back roll swing arm assembly; 5-loop back roll assembly; 6-bearing pin.
detailed description of the invention:
For making the purpose of this utility model, technical scheme and advantage clearly understand, below by the specific embodiment shown in accompanying drawing, the utility model is described.But should be appreciated that, these describe just exemplary, and do not really want to limit scope of the present utility model.In addition, in the following description, the description to known features and technology is eliminated, to avoid unnecessarily obscuring concept of the present utility model.
As shown in Figure 1-2, the utility model provides a kind of technical scheme: looper between a kind of finishing mill, comprise mill housing 1, cylinder pedestal 2, hydraulic cylinder 3, loop back roll swing arm assembly 4 and loop back roll assembly 5, described cylinder pedestal 2 is arranged on mill housing 1, described hydraulic cylinder 3 lower end is connected with cylinder pedestal 2, described hydraulic cylinder 3 upper end is connected with loop back roll swing arm assembly 4, described loop back roll assembly 5 is arranged on loop back roll swing arm assembly 4, described loop back roll assembly 5 is all fixed on above mill housing 1 with loop back roll swing arm assembly 4, pressure sensor and displacement transducer is provided with in described hydraulic cylinder 3.
Particularly, hydraulic cylinder 3 lower end is connected with cylinder pedestal 2 by bearing pin 6.
Its course of work: when band does not arrive, loop back roll is in level, after steel enters next rolling mill when band, fall the reasons such as speed during owing to nipping, the band between frame creates certain cover amount, and at this moment loop back roll rises at once, being with steel tensioning.The angle of at this moment loop back roll swing arm should be between minimum and maximum functional angle, if the angle of kink swing arm is less than minimum operating angle, the displacement transducer on loop back roll arm shaft sends signal, and next rolling mill is slowed down, and increases kink amount.If the angle of kink swing arm is greater than the maximum functional angle of loop back roll, the displacement transducer on loop back roll arm shaft also sends signal, makes next rolling mill speedup.
Particularly, hydraulic cylinder 3 drives loop back roll swing arm assembly 4 and drives loop back roll assembly 5 to swing, and detects strap tension, feed back to Hydrauservo System by the pressure sensor of hydraulic cylinder 3 inside, change the stroke of hydraulic cylinder 3, thus change the position of loop back roll assembly 5.In addition, the displacement transducer in hydraulic cylinder 3 can detect the pendulum angle of loop back roll, and this value is fed back to main mill, changes the speed of main mill, to meet hot continuous rolling process needs.
More than show and describe general principle of the present utility model and principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; what describe in above-described embodiment and description just illustrates principle of the present utility model; under the prerequisite not departing from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
