The measuring and control device for measuring the elongation of the withdrawal and straightening machine comprises a real time monitoring device of the elongation and a control device of the elongation, wherein the real time monitoring device comprises a first speed disk and a second speed disk which are respectively used for measuring the speed of a strip steel on the position of an entrance roller and an exit roller. The real time monitoring device further comprises a first encoder and a second encoder, wherein the first encoder encoder and the second encoder are respectively and coaxially installed with the first speed disk and the second speed disk, and the data of the first encoder and the second encoder are input from a twin channel input deviation measuring meter. The measuring and control device for measuring the elongation of the withdrawal and straightening machine is capable of real-timely measuring and adjusting the elongation of the strip steel of the withdrawal and straightening machine so that rejection rate and defective rate can be reduced to a large extent.
Description
Technical field
The utility model relates to a kind of withdrawal straightening machine percentage elongation measure and control device.
Background technology
Withdrawal straightening machine is again stretch bending-straightening machine, and hot galvanizing plate will produce irregular deformation aborning, and for example: the extension of steel edge portion ratio of elongation middle part just forms unrestrained limit when large; Limit section ratio of elongation middle part is extended and hour is just formed the wooden dipper song.In order to reach the following process requirement, use multiple method for aligning in the factory, application more widely equipment is multi-roll straightening machine, and thin plate is by behind this straightener, and itself does not produce extension, just billow is turned to moderate seas, the plate face is close to straight.And for the sheet material of thickness of slab less than 0.8mm, be difficult in this way aligning.And withdrawal straightening machine can make thin plate produce simultaneously the vertical and horizontal distortion, thereby substantially improves glacing flatness and the material property of thin plate, makes the thin plate straightening technology greatly improve a step.In the stretch-bending straightening operation process, percentage elongation is one of important distortion index, and percentage elongation should be controlled at can eliminate yield point elongation, does not produce again in the scope of work hardening, and on technique, each requires certain percentage elongation with the steel capital.Therefore, just require, when using withdrawal straightening machine that the band steel is aligned, can the Real-Time Monitoring percentage elongation, and can proofread and correct undesirable percentage elongation.
The utility model content
The purpose of this utility model is to adapt to the reality needs, and a kind of withdrawal straightening machine percentage elongation measure and control device is provided.
In order to realize the purpose of this utility model, the technical solution adopted in the utility model is:
A kind of withdrawal straightening machine percentage elongation measure and control device, comprise percentage elongation real-time monitoring device and elongation control device, described real-time monitoring device comprises the first tachometer disc and the second tachometer disc that is respectively applied to measure entrance roller and outlet roller place strip speed, also comprise the first encoder and the second encoder, described the first encoder and the second encoder respectively with the first tachometer disc and the coaxial installation of the second tachometer disc, the data that described the first encoder and the second encoder gather are inputted from dual input deviation measuring apparatus table.

Described elongation control device comprise be respectively applied to drive unreel 8, rolling 9 unreel motor 10, winding motor 11, described unreel to be respectively equipped with on motor 10, the winding motor 11 unreel speed regulator and rolling speed regulator.
Use principle of the present utility model is summarized as follows:
Such as Fig. 1, arrow is depicted as the running orbit with steel 12 among the figure, band steel 12 is successively through unreeling 8, entrance roller 1, withdrawal straightening machine 13, outlet roller 2 is by rolling 9, the first tachometer disc 3 and the second tachometer disc 4 are measured the speed of entrance roller 1 and outlet roller 2 place's band steel respectively, the first encoder 5 and the second encoder 6 are counted the first tachometer disc 3 and the second tachometer disc 4 respectively, the data that the first encoder 5 and the second encoder 6 gather are inputted from dual input deviation measuring apparatus table 7, dual input deviation measuring apparatus table 7 has been implanted algorithm routine in advance, and measured value can be shown in real time.
According to dual input deviation measuring apparatus table 7, to unreel on motor 10, the winding motor 11 unreel speed regulator and the rolling speed regulator is regulated, namely regulated the rotating speed that unreels motor 10, winding motor 11, the rotating speed of entrance roller 1, outlet roller 2 is also adjusted, finally can obtain satisfactory percentage elongation.
What embodiment of the present utility model announced is preferred embodiment; but be not limited to this; those of ordinary skill in the art; very easily according to above-described embodiment; understand spirit of the present utility model; and make different amplifications and variation, but only otherwise break away from spirit of the present utility model, all in protection domain of the present utility model.
