Description
Technical field
The invention belongs to milling train operation field, is a kind of non-polar oblique wedge adjustment mechanism.
Background technology
In line of rolling apparatus, due to the variation of roller system, often to carry out the adjusting operation of rolling line.Especially large-sized rolling mills, roller is that grinding excursion is large, just needs the wedge adjusting equipment of large stroke to complete, and large-sized rolling mills, rolling line adjusting device is generally arranged on top or bottom, and manual observation or adjustment are all inconvenient, this just requires the necessary automatic Memory in its position, and position is adjusted automatically; Employing small-sized journey rolling line adjustment and backing plate that the adjustment of domestic milling train rolling line has are combined use, by manually adding backing plate, the defect of this way be adjust position inaccurate, cause that long, labour intensity of rolling line adjustment time is highly difficult for, rolling line automation adjustment; Some employing stepped plates add wedge, and by Hydraulic Cylinder, the defect of this way is that device is more complicated, and the space taking is larger, and should not be arranged in the bottom of mill housing.
Summary of the invention
The object of the invention is provides a kind of stroke adjustment greatly, simple and convenient, the reliable non-polar oblique wedge adjustment mechanism of performance safety for large-sized rolling mills production line.
Technical scheme of the present invention is a kind of non-polar oblique wedge adjustment mechanism, which comprises at least leading screw, approach switch, hydraulic motor, two bearings, two angled-lift splitses, photoelectric encoder and PLC controllers, it is characterized in that: two bearings are fixed on mill housing; Two angled-lift splitses are fixed on leading screw homonymy by nut; On two bearings, have the chute that coordinates angled-lift splits, angled-lift splits is placed in the chute of bearing; Hydraulic motor is connected with leading screw by shaft coupling; Non-polar oblique wedge adjusting device connects PLC controller, and is controlled by the approach switch being arranged on leading screw; Non-polar oblique wedge adjusting device is also connected into computer by photoelectric encoder.
The inclined-plane Mirror Symmetry of two described angled-lift splitses.
Described connection leading screw and the nut of angled-lift splits are copper nuts, and the thread rotary orientation of leading screw is contrary.
Feature of the present invention is that hydraulic pressure, electronic control technology and mechanical device are combined, and has adjustment stroke large, simple and compact for structure, and performance safety is reliable, operation automation is high, set feature easily, can be used in various large-sized rolling mills production lines.That this device has been successfully applied to is large-scale by four, in six roller cold continuous rolling production lines.
Accompanying drawing explanation
Below in conjunction with embodiment, the present invention is further illustrated:
Fig. 1 is the structural representation of non-polar oblique wedge adjusting device.
In figure: 1, approach switch; 2, leading screw; 3, bearing one; 4, angled-lift splits one; 5, copper nut; 6, bearing two; 7, angled-lift splits two; 8, hydraulic motor.
The specific embodiment
Embodiment: as shown in Figure 1, this non-polar oblique wedge adjustment mechanism, which comprises at least leading screw 2, approach switch 1, hydraulic motor 8, two bearings, two angled-lift splitses, photoelectric encoder and PLC controllers, it is characterized in that: two bearings are fixed on mill housing; Two angled-lift splitses are fixed on leading screw homonymy by nut; On two bearings, have the chute that coordinates angled-lift splits, angled-lift splits is placed in the chute of bearing; Hydraulic motor 8 is connected with leading screw 2 by shaft coupling; Non-polar oblique wedge adjusting device connects PLC controller, and is controlled by the approach switch 1 being arranged on leading screw; Non-polar oblique wedge adjusting device is also connected into computer by photoelectric encoder.
Described leading screw 2 can be provided with approach switch 1 and be connected into PCL controller in left side, right side is connected with hydraulic motor 8 by shaft coupling, the extreme higher position of non-polar oblique wedge adjusting device and extreme lower position detect by approach switch 1, signal is sent into the control system of PCL controller, realizes the chain control under various states; Non-polar oblique wedge adjusting device records its lifting process by photoelectric encoder, and is delivered to computer, in conjunction with roller, is that changing value can reach setting value automatically.
Leading screw 2 can be fixedly connected with angled-lift splits 27 with angled-lift splits 1 by copper nut 5, the inclined-plane of two described angled-lift splitses can Mirror Symmetry, be that angled-lift splits 1 is the inclined-planes that have to tilt to upper left side, angled-lift splits 27 is the inclined-planes that have to tilt to upper right side, the inclined-plane of two angled-lift splitses is Mirror Symmetry, and fixedly the screw rotation direction of the copper nut of use is contrary, guarantee the skewback lifting simultaneously at two places.
Bearing 1 is fixed on mill housing with bearing 26, and has the chute matching with angled-lift splits.
The angled-lift splits 1 of leading screw 2 and angled-lift splits 27 are placed in the chute of bearing 1 and bearing 26, and by fluid motor-driven, angled-lift splits can slide on bearing, and meanwhile, PLC controller and approach switch guarantee that angled-lift splits can not drop out from the chute of bearing.Like this can be in larger travel range, compensating roller is the variable quantity of central roll footpath grinding, according to input changing value, automatically reaches the mechanism of desired location, for the adjustment of rolling mill of large-sized rolling mills production line.
During work, hydraulic motor 8 drives leading screw 2 to drive angled-lift splits to slide along the slideway of bearing, PCL controller is realized the chain control under each state by approach switch 1, photoelectric encoder is inputted computer realization by data and is automatically controlled, this device combines hydraulic pressure, electronic control technology and mechanical device, has adjustment stroke large, simple and compact for structure, performance safety is reliable, operation automation is high, set feature easily, can be used in various large-sized rolling mills production lines.
It should be noted that well-known components and common structure or conventional means that parts that the present embodiment does not describe in detail and structure belong to the industry, here narration one by one.Hydraulic motor, PCL controller and photoelectric encoder are the common equipments of this area, and it uses and method of operating is not done special introduction at this yet.
