Abstract
The invention relates to a rapid calibration method for hot-rolled coiled side guide plates. The rapid calibration method comprises the following steps of: mounting displacement sensors for detecting the displacement of the side guide plates in cylinders of the two side guide plates; mounting a calibration device in a positioning hole of a roller way between the two side guide plates; pulling out telescopic rods on the two sides of the calibration device, and pressing the telescopic rods against the two side guide plates; and checking the length of the telescopic rods and transmitting measured data to a programmable logic controller (PLC). The method can be used for reducing the calibration time of the coiled side guide plates and ensuring the coiling quality.
Description
Technical field
The present invention relates to plate rolling side guide calibration technique field, particularly relate to a kind of capable for hot-rolling rolled side guide quick calibrating method.
Background technology
Existing hot-rolled coil flipper guide scaling method is that the roller-way in the middle of two flipper guides is put a calibrating block that size is certain, repeatedly presss from both sides the demarcation base with flipper guide, manually repeatedly uses the real data at dipstick metering scene, enters data into the HMI picture again.
This method has two defectives, the one, every time demarcation all needs with driving calibrating block to be hung roller-way and flipper guide calibration position, nominal time is very long, approximately needs more than half an hour, does not have the sufficient time to demarcate when shutting down at ordinary times little roll change or short time, can only be arranged in periodical repair or carry out when shutting down for a long time, inconvenient flexibly, moreover when the demarcation condition is arranged, the use of driving with the roll change of rolling line, overhaul to have and conflict, can affect the carrying out of other overhauling project, often can't carry out; The 2nd, operating personnel will be repeatedly measure up and down at roller-way back and forth carrying out timing signal, and not only workload is large, also has certain potential safety hazard.
Summary of the invention
Technical problem to be solved by this invention provides a kind of capable for hot-rolling rolled side guide quick calibrating method, can reduce the time that plate rolling side guide is demarcated, and guarantees reeling quality.
The technical solution adopted for the present invention to solve the technical problems is: a kind of capable for hot-rolling rolled side guide quick calibrating method is provided, may further comprise the steps:
(1) displacement transducer for detection of the flipper guide displacement all is installed in the oil cylinder of two flipper guides;
(2) caliberating device is installed in the locating hole of two flipper guide delay tables;
(3) pull out the expansion link of caliberating device both sides, make expansion link withstand two flipper guides;
(4) check length of telescopic bar and the data that record are sent into the PLC controller.
Also comprise in the described step (4) expansion link of caliberating device both sides is retracted, two flipper guides of manual operation open or close certain position, repeating step (3) and step (4), the step that the data that record and the data of sending into the PLC controller are compared.
Described caliberating device comprises sleeve and connecting rod, each side is provided with an expansion link in the described sleeve; On the described sleeve along sleeve axially have a groove, described connecting rod passes groove and links to each other with described expansion link, described connecting rod can slide along described groove; Also be provided with two and the orthogonal alignment pin of sleeve on the described sleeve.
Described sleeve is marked with graduation mark.
Described connecting rod is provided with handle.
Described two alignment pins are parallel to each other, and are connected with support between two alignment pins.
Beneficial effect
Owing to having adopted above-mentioned technical scheme, the present invention compared with prior art has following advantage and good effect: the present invention can directly realize on the existing equipment basis, need not increase too many investment, with low cost, realize simple.As long as the present invention manually sees the scale on the calibration tool, do not need repeatedly to stand on the roller-way for a long time to measure, not only reduce workload, also reduced potential safety hazard.After using the method, flipper guide is demarcated need not use the traveling crane calibrating block, and the time is approximately 10 minutes, saves 3-4 times of time than original method, can carry out when the short time shuts down arbitrarily.By checking, adopt this scaling method to demarcate after, the flipper guide opening degree is accurate, uses very stablely, service precision has improved a grade (having brought up to the mm level by original cm level).The present invention can the Reduction of failure time, improve output, ensure the quality of products.
