The inclined faces of the upward pressing bracket and the sliding lump satisfy the self-locking condition, and the transference of the stress born by the hydraulic oil cylinder onto the sliding lump improves the service life of the hydraulic oil cylinder, with the structure simple and reliable and maintenance and control convenient.
Description
Technical field
The roll that the utility model relates to a kind of stress metal processing unit (plant) is the roll gap adjusting device radially, especially for the lower roll pressuring upper device of section bar roller mill.
Background technology
At present, the lower roll pressuring upper device of known bar and shape mill comprises pressing support, guider, slide block, mainly contains two types: a kind of is the hydraulically powered roll gap adjusting device that presses, band liquid presses piston pole, hydraulic jack and hydraulic control system; A kind of be machine driving drive press the roll gap adjusting device.Existing hydraulic pressure pressuring upper device is to adopt the liquid presses piston pole that vertically is placed on below the roll shaft directly to drive to press support to realize moving up and down, this is simple in structure, but the pressure in the operation of rolling acts directly on the hydraulic cylinder, add under the roll shaft that hydraulic cylinder vertically is in, requirement height to hydraulic cylinder and liquid presses piston pole, the poor working environment of hydraulic cylinder, particularly the care and maintenance difficulty of hydraulic cylinder and liquid presses piston pole when the relatively large material of compacting.The drive part structure more complicated of the pressuring upper device that machine driving drives, the oxide skin in the operation of rolling falls down also to fall easily in transmission mechanism, causes job failure, safeguards inconvenience.It is the lower roll pressuring upper device that CN2133376Y is applicable to bar and shape mill that Patent Office of the People's Republic of China discloses a kind of notification number on May 19th, 1993, this device drives the bevel gear rotation by rotating handwheel, bevel gear drives the wedge that cooperates with wire rod thread and moves horizontally, and drives lifting column when wedge moves horizontally and rises or descend to realize the radially adjustment of lower roll.This structure transmission mechanism complexity, the transmission node is many, and efficient is low, and the oxide skin in the operation of rolling falls down through regular meeting and is stuck in the transmission mechanism, causes job failure, safeguards inconvenience; Threaded engagement between screw mandrel and the wedge is easy to generate sliding tooth and causes regulate losing efficacy in addition, and regulates by hand, relatively effort.
Summary of the invention
The hydraulic cylinder works environment that existing roll gap adjusting device structure exists is poor in order to overcome, the maintaining difficulty, and machine driving drives structure complexity, cause the shortcoming of job failure easily, the utility model provides a kind of roll gap adjusting device, and it is simple and reliable for structure, control and maintaining convenient.
The utility model is that the technical scheme that its technical problem of solution is adopted is: a kind of roll gap adjusting device, comprise the hydraulic jack and the hydraulic control system that press support, guider, slide block, band liquid presses piston pole that support lower roller shaft bearings at both ends case, this presses the support below an inclined-plane, press support by inclined-plane and slide block plane contact with identical inclined-plane, slide block moves horizontally under the driving of hydraulic jack, the hydraulic jack horizontal positioned, press support and under the inclined-plane of slide block promotes, move up and down, realize the adjustment of roll gap gap size.
As further improvement of the utility model, press the inclined-plane self-locking conditions satisfied of support and slide block, promptly the tangent value of the angle of inclined-plane and horizontal plane is less than the coefficient of contact friction that presses between support and slide block.Like this, pressing the active force that support bears can all act on the slide block, can not impact to liquid presses piston pole.
The utility model makes the simple in structure of roll gap adjusting device owing to use hydraulic-driven, and is easy to operate; Press the downward active force that support bears and act on the slide block, can not act directly on the hydraulic cylinder, can improve the working strength and the service life of hydraulic cylinder; The hydraulic cylinder horizontal positioned, the position beyond can being placed under the roll shaft can significantly reduce high temperature scale and fall thereon, improves the working environment of hydraulic cylinder, can further facilitate maintenance.By hydraulic control system operation control height up and down, not only simply but also accurate.
As further improvement of the utility model, the liquid presses piston pole on the hydraulic cylinder of above-mentioned horizontal positioned also can be connected with slide block by connecting rod, drives slide block with drive link and moves horizontally.Can guarantee that like this hydraulic jack and hydraulic control system away from the rolling workspace, help the maintenance to hydraulic cylinder and hydraulic control system.
In sum, the beneficial effects of the utility model are: simple in structure, operation is accurately convenient, and the good work environment of roll gap adjusting device is easy to maintenance.

1. press support among the figure, 2. slide block, and 3. liquid presses piston pole, 4. hydraulic cylinder, 5. hydraulic control system, 6. lower roller shaft is 7. gone up roll shaft, 8. guider, 9. workpiece, 10. connecting rod, 13. inclined-planes.
The specific embodiment
In the embodiment shown in fig. 1 as can be known, the utility model supports the bearing housing of lower roller shaft 6 by pressing support 1, presses support 1 and can only move up and down under the restriction of as shown in Figure 2 guider 8.The inclined-plane 13 that presses support 1 below with have slide block 2 plane contact on equal angular inclined-plane, pressing can slip on the inclined-plane 13 that contacts mutually between support 1. and the slide block 2.Slide block 2 is connected with the liquid presses piston pole 3 of horizontal positioned, and hydraulic cylinder 4 is by hydraulic control system 5 controls.During work, under the effect of hydraulic control system 5, liquid presses piston pole 3 moves horizontally, driving slide block 2 moves horizontally, effect by inclined-plane 13 promotes to press support 1 and moves up and down, thereby realizes adjusting the distance between lower roller shaft 6 and the last roll shaft 7, has promptly adjusted the roll gap of up-down rollers between centers.According to the needs of practical work piece 9, can conveniently realize adjustment to the roll gap size.
The liquid presses piston pole 3 of the horizontal positioned in embodiment illustrated in fig. 4 is connected with slide block 2 by connecting rod 10, during work, under the control of hydraulic control system 5, liquid presses piston pole 3 drives slide block 2 by connecting rod 10 and moves horizontally, thereby promoting support moves up and down, reach the roll gap distance of adjusting the up-down rollers between centers, satisfy the needs of real work.Certainly, the moving direction that liquid presses piston pole 3 drives slide blocks 2 by connecting rod 10 is positioned at that the axis of lower roller shaft is consistent understand better assurance hydraulic jack and hydraulic control system away from the rolling workspace, help maintenance, can guarantee that also hydraulic cylinder has good working environment hydraulic cylinder and hydraulic control system.
The utility model is not limited to the roll gap adjustment between top and bottom rolls roll shaft on the bar and shape mill, also can be used for the adjustment of the lower roll height of roll shaft squeezer, also can be used for lower roller shaft and last roll shaft and is in roller mill on the vertical line.
