Description
Technical field
The invention belongs to milling train operation field, is a kind of electrodeless wedge guiding mechanism.
Background technology
In line of rolling apparatus, because the variation of roller system often will be carried out the adjustment operation of rolling line.Especially large-sized rolling mills, roller is that the grinding excursion is big, just needs the wedge adjusting equipment of big stroke to accomplish; And large-sized rolling mills, rolling line adjusting device generally is installed in top or bottom, and manual observation or adjustment are all inconvenient; This just requires the memory automatically of its position, and the position is adjusted automatically; The small-sized journey rolling line adjustment of the employing that the adjustment of domestic milling train rolling line has is united use with backing plate, adds backing plate by manual work, the defective of this way be the adjustment position inaccurate, cause high difficult, the rolling line automation of long, labour intensity of rolling line adjustment time to adjust; The employing stepped plate that has adds wedge, is promoted by hydraulic cylinder, and the defective of this way is that device is complicated, and occupation space is bigger, and should not be arranged in the bottom of mill housing.
Summary of the invention
The objective of the invention is provides a kind of stroke adjustment greatly, simple and convenient, electrodeless wedge guiding mechanism that performance is safe and reliable for the large-sized rolling mills production line.
Technical scheme of the present invention is a kind of electrodeless wedge guiding mechanism, which comprises at least leading screw, near switch, hydraulic motor, two bearings, two angled-lift splitses, photoelectric encoder and PLC controllers, and it is characterized in that: two bearings are fixed on the mill housing; Two angled-lift splitses are fixed on the leading screw homonymy through nut; On two bearings the chute that cooperates angled-lift splits is arranged, angled-lift splits places the chute of bearing; Hydraulic motor links to each other with leading screw through shaft coupling; Electrodeless wedge adjusting equipment connects the PLC controller, and by being installed in controlling near switch on the leading screw; Electrodeless wedge adjusting equipment also is connected into computer through photoelectric encoder.
The flat inclined mirror of described two angled-lift splitses is in the face of claiming.
The nut of described connection leading screw and angled-lift splits is a copper nut, and the thread rotary orientation of leading screw is opposite.
Characteristics of the present invention are to combine hydraulic pressure, electronic control technology and mechanical device, and it is big to have adjustment stroke, simple and compact for structure, and performance is safe and reliable, operation automation is high, set characteristics easily, can be used in the various large-sized rolling mills production lines.That this device has been successfully applied to is large-scale by four, in the six roller cold continuous rolling production lines.
Description of drawings
To combine embodiment that the present invention is further described below:
Fig. 1 is the structural representation of electrodeless wedge adjusting equipment.
Among the figure: 1, near 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 electrodeless wedge guiding mechanism which comprises at least leading screw 2, near switch 1, hydraulic motor 8, two bearings, two angled-lift splitses, photoelectric encoder and PLC controllers, and it is characterized in that: two bearings are fixed on the mill housing; Two angled-lift splitses are fixed on the leading screw homonymy through nut; On two bearings the chute that cooperates angled-lift splits is arranged, angled-lift splits places the chute of bearing; Hydraulic motor 8 links to each other with leading screw 2 through shaft coupling; Electrodeless wedge adjusting equipment connects the PLC controller, and by being installed in controlling near switch 1 on the leading screw; Electrodeless wedge adjusting equipment also is connected into computer through photoelectric encoder.
Described leading screw 2 can be equipped with near switch 1 and be connected into the PCL controller in the left side; The right side is connected with hydraulic motor 8 through shaft coupling; The extreme higher position of electrodeless wedge adjusting equipment and extreme lower position are by detecting near switch 1; Signal is sent into the control system of PCL controller, realizes the chain control under the various states; Electrodeless wedge adjusting equipment writes down its lifting process through photoelectric encoder, and is delivered to computer, is that changing value can reach setting value automatically in conjunction with roller.
Leading screw 2 can be fixedly connected with angled-lift splits 27 with angled-lift splits 1 through copper nut 5; The inclined-plane of described two angled-lift splitses can minute surface symmetry; Be that angled-lift splits 1 is the inclined-planes that have to tilt to the upper left side, angled-lift splits 27 is the inclined-planes that have to tilt to the upper right side, and the inclined-plane of two angled-lift splitses is the minute surface symmetry; And fixedly the screw rotation direction of the copper nut of usefulness is opposite, guarantees that the skewback at two places goes up and down simultaneously.
Bearing 1 is fixed on the mill housing with bearing 26, and has the chute that matches with angled-lift splits.
The angled-lift splits 1 of leading screw 2 and angled-lift splits 27 place the chute of bearing 1 and bearing 26, and through fluid motor-driven, angled-lift splits can slide on bearing, simultaneously, and PLC controller and guarantee that near switch angled-lift splits can not drop out from the chute of bearing.Like this can be in big travel range, compensating roller is the variable quantity of central roll footpath grinding, according to the input changing value, reaches the mechanism of desired location automatically, is used for the milling train adjustment of large-sized rolling mills production line.
During work, hydraulic motor 8 drives leading screw 2 and drives the slideway slip of angled-lift splits along bearing, the chain control of PCL controller through realizing under each state near switch 1; Photoelectric encoder is imported computer realization with data and is controlled automatically; This device combines hydraulic pressure, electronic control technology and mechanical device, and it is big to have adjustment stroke, and is simple and compact for structure; Performance is safe and reliable, operation automation is high, set characteristics easily, can be used in the various large-sized rolling mills production lines.
It should be noted that well-known components and common structure or conventional means that parts that present embodiment is not described 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.
