Description
Technical field
The present invention relates to rolling machinery technical field of automatic control, more particularly to a kind of Double-side-shearing pinch roll hydraulic cylinder to prevent
Hit prior-warning device and anti-collision early warning method.
Background technology
At present, shearing of the domestic and international Heavy Plate Production enterprise to steel plate edge is most uses rolling-cut double side shear, general
Mechanical structure is to install a set of pinch roll apparatus respectively in bilateral scissors entrance and exit, often covers pinch roll apparatus by 4 pinch rolls
Composition, is divided into affixed side and mobile side, is divided into top pinch roll and bottom pinch roll again per side, top pinch roll passes through a hydraulic cylinder reality
Existing oscilaltion, steel plate is pressed between upper bottom pinch roll and is used to clamp steel plate stepping shearing.
Because bilateral scissors movement side pinch roll is that as bilateral scissors move, side body is traversing to be moved together according to steel plate width,
During actual shearing, bilateral scissors entrance movement side pinch roll lifting hydraulic cylinder or hydralic hose often occurs by steel plate
The accident hit by mistake, the substantial equipment accidents such as the deformation of pinch roll hydraulic cylinder piston rods bend, cylinder body and sebific duct oil leak are caused, once leakage
Oily splash can cause surface of steel plate to pollute to surface of steel plate, have a strong impact on product quality.Counted according to certain steel mill, such case is average
It can all occur 5-6 times every year, at one month, inscribed running fire life broke hydraulic cylinder accident twice during most serious, and changed hydraulic pressure every time
Cylinder and sebific duct etc. are required for 3-4 hours, close when hydraulic cylinder damage is serious to scrap.
Generation steel plate colliding entries movement side pinch roll hydraulic cylinder accident has following several respects reason：（1）Operating personnel grasp
Slip up, be such as manually entered steel plate error in data, steel plate developed width is more than the traversing opening width of bilateral scissors body；（2）It is bilateral
The traversing position coder failure of body is cut, feedback data is untrue, and the traversing actual range of bilateral scissors body shows this with HMI pictures
The traversing width of body is not inconsistent；（3）Actual rolling size and the gross data deviation of steel plate is too big, passed under computer two level steel plate data and
Steel plate developed width is not inconsistent；
Problem above objective reality, to tackle the problem at its root, the best way is to develop a kind of anti-collision early warning system
To prevent the generation of accident.
The content of the invention
, can be from root the invention provides a kind of Double-side-shearing pinch roll hydraulic cylinder anti-collision prewarning apparatus and anti-collision early warning method
Prevent Double-side-shearing pinch roll hydraulic cylinder from being hit the generation of accident by mistake in sheet, loss caused by avoiding accident, ensure holding for production line
Continuous stable operation.
In order to achieve the above object, the present invention is realized using following technical scheme：
A kind of Double-side-shearing pinch roll hydraulic cylinder anti-collision prewarning apparatus, before whole device is arranged on entrance pinch roll hydraulic cylinder
Side, close to the side that steel plate enters, including connecting bolt, support, turnover panel, sleeve, hook, extension spring, proximity switch, the support
Formed by steel-pipe welding, external part is fixed in the frame of bilateral scissors with connecting bolt, welded sleeve on turnover panel, and passes through sleeve
On the transverse axis stretched out installed in side face, turnover panel is at a right angle with support and integrally can be rotated around transverse axis, above support and turnover panel
Appropriate location welding hook, the both ends of extension spring are hung on the hook of support and turnover panel, the original of turnover panel in the presence of extension spring
Beginning state keeps vertical, and proximity switch is arranged on rack beam.
Proximity switch sends signal and passes to bilateral scissors PLC control system, sends quick parking letter immediately by PLC control system
Number.
In HMI（Man-machine interface）Upper increase stops alarm screen soon, while PLC control system sends quick stop sign,
Occur presetting on HMI interfaces stops alarm screen soon.
A kind of Double-side-shearing pinch roll hydraulic cylinder anti-collision early warning method, utilize above-mentioned Double-side-shearing pinch roll hydraulic cylinder anti-collision early warning
Device carries out anti-collision early warning and mainly included the following steps that：
1. stopping to test according to electric braking and determining safe distance, anti-collision prewarning apparatus is installed in position, it is determined that connecing
The best position closely switched；
2. change and debug bilateral scissors PLC control program, in HMI（Man-machine interface）Upper increase stops alarm screen soon；
3. after turnover panel bottom is bumped against by steel plate, being rotated around support transverse axis, proximity switch sends signal and passes to bilateral scissors PLC controls
System processed；
4.PLC control systems send quick stop sign immediately, and bilateral scissors front roller-way and entrance pinch roll carry out electricity immediately
Gas Brake stop, while occur presetting on HMI interfaces stops alarm screen soon；
5. after parking, bilateral scissors control mode is changed to manual manipulation mode, by pinch roll hydraulic cylinder anti-collision prewarning apparatus
On extension spring unload, block proximity switch with buting iron, HMI resetted, now bilateral scissors front roller-way and pinch roll possess transports again
The condition turned, manual manipulation retract steel plate from Double-side-shearing pinch roll porch；
6. the extension spring on pinch roll hydraulic cylinder anti-collision prewarning apparatus is reinstalled, the gear for blocking proximity switch is removed
Iron, anti-collision prewarning apparatus recover normal operating conditions.
Compared with prior art, the beneficial effects of the invention are as follows：
Install panel turnover device and proximity switch additional, real-time anti-collision early warning is realized by human-computer dialogue and programme-control and promptly stopped
It car, can fundamentally prevent Double-side-shearing pinch roll hydraulic cylinder from being hit the generation of accident by mistake, loss caused by avoiding accident, ensure
The continual and steady operation of production line.
