The sleeve notch is a sleeve on a mandrel of a coiling machine of a steel mill, and a groove is formed in the soft base rubber sleeve for inserting a belt head; the strip head mark is a transverse indentation with regular intervals on the strip steel due to the thickness of the strip head under the action of coiling tension in the coiling process of the cold-rolled strip steel.
When the cold rolling leveling machine set uses a common sleeve, the belt head mark is obvious, especially the thick strip steel, and the length can reach hundreds of meters when severe; in the production process of the thin plate, the elastic sleeve (commonly called as a rubber sleeve) is adopted for coiling, so that the indentation (crease) of the thin plate caused by the fan-shaped block of the scroll is eliminated, but the indentation of the inner layer of the steel coil caused by the strip head of the strip steel cannot be eliminated.
In view of the above, the application provides a method and a device for positioning a belt head of a cold rolling temper mill, which can press the belt head fold in a sleeve groove through accurate positioning, thereby effectively solving the problem of belt head indentation.
Example 1
Referring to fig. 1 and 2, an embodiment of the present application provides a method for positioning a strip head of a cold rolling temper mill, which includes a notch positioning logic control and a threading cooperation logic control;
in the notch positioning logic control process, the notch opening area of the soft belt sleeve of the coiling machine is positioned to be appointedθAngular position, when the soft belt sleeve notched area of the coiling machine is from the specifiedθWhen the angle position reaches the overlapping position of the belt head, the belt head reaches the overlapping position on the coiling machine;
in the threading cooperation logic control process, after the notch is positioned, the tape head is threaded according to the preset threading speed, when the tape head advances to reach the photoelectric switch on the threading guide plate in front of the coiling machine, the coiling machine is started, and when the tape head reaches the coiling machine, the tape head coincides with the notch opening area of the soft tape sleeve on the sleeve.
In this embodiment, there are two main control processes for tape head positioning: notch positioning logic control and threading cooperation logic control. First, the notched area of the soft belt sleeve of the coiling machine is positioned to a certain appointed areaθAngular position. SpecifyingθThe angular position ensures that the tape head just reaches the overlapping position on the coiler when the coiler notched area reaches the tape head overlapping position from this position. Threading is matched with a logic control process, threading is started after the notch is positioned, the tape head is threaded according to the normal threading speed of 25m/min (the winding machine is not rotated at the moment), when the tape head continuously advances to reach the photoelectric switch on the threading guide plate in front of the winding machine, the winding machine starts to be started, and when the tape head reaches the winding machine, the position of a soft tape slot on the sleeve is overlapped.
In the embodiment, when the winding aid contacts the belt head, the winding machine is controlled to reach the belt threading speed; the length of the strip steel running track between the projection point of the photoelectric switch above the outlet strip threading guide plate on the strip steel and the biting gap of the wrapper is L; the time t for the tape head to walk within the distance L is greater than the time required for the coiler to start accelerating from 0 to the exit threading speed V.
And controlling the coiling machine to adopt a constant acceleration operation mode in the time t.
As the preferable scheme of the tape head positioning method of the cold rolling temper mill, the method is specifiedθThe determination formula of the angle position is as follows:
wherein L is 1 In the time t, the distance that the soft belt sleeve notched area walks on the sleeve surface; d is the diameter of the sleeve; v is the exit threading speed.
Distance L travelled by the notched area of the soft belt sleeve on the sleeve surface within time t 1 The method comprises the following steps:
wherein a is the constant acceleration of the outlet design operation, t 1 V is the exit threading speed for the acceleration time required by the coiler.
Specifically, the accurate positioning of the tape head is to position the tape head just to the notch position of the sleeve. In this embodiment, a photoelectric switch is mounted on the threading guide table, and the photoelectric switch is used to detect that the tape head reaches the position to start the coiler. According to the parameters of the field device, the diameter D of the sleeve is 610mm, the outlet threading speed V is 0.417 m/s, the length of the strip steel running track between the projection point of the photoelectric switch above the outlet threading guide plate on the strip steel and the biting gap of the wrapper is L, and the L is 1.5m through actual measurement. Since the coiler is started after the tape head signal is detected by the tape head detecting element, the coiler reaches the threading speed when the tape head is contacted by the wrapper, and therefore the time t for the tape head to walk within the distance L is longer than the time required for the coiler to accelerate from 0 start to v. From the following componentsThe calculation can be as follows: />
I.e. the constant acceleration mode of operation employed by the coiler during this time t=3.59 s, the exit design operating accelerationa=0.6m/s 2 Therefore, the acceleration time required for the coiler is:
distance travelled by the soft zone on the sleeve surface during time t:
thus, the soft belt sleeve notched area of the coiling machine is positioned to be appointedθThe angular position determination formula is:
further, the grooved region remains in the position before the coiler is startedθThe angle position can accurately position the belt head at the notch position during belt threading, and the belt head can coincide on time.
With the assistance of FIG. 2, in this embodiment, the slot positioning logic is controlled within the AC80 control, and the program includes a chain, positioned inθThe angle position is realized by a PC element block, and can be well determined by repeated debuggingθAngular position.
The notch positioning logic is controlled in the AC80, and the main reason is that the notch positioning logic can respond faster to the transmission system communication, ensure the consistency in time sequence, set the speed of the coiling machine to be 5m/min in the positioning process, and compensate on time slices according to different incoming material thicknesses.
The threading is matched with logic control to be mostly realized in AC450 control, the coordination with production line equipment is mainly considered, AF100 network communication is adopted for communication, the threading takes the speed of a rolling mill as the main command speed, and the matching of the speeds of all motors is ensured. After the threading is finished, the normal mode needs to be switched. It should be noted that during the process of tape head positioning, there may be a failure, such as a clamping of the tape during threading, and repositioning may be performed, or a selection may be received, and the decision may be held in the hands of the operator.
In the embodiment, when the butt joint of the belt head and the notched area of the soft belt sleeve is finished and the belt head and the notched area of the soft belt sleeve are wrapped by the belt winding aid for one circle, the belt head and the soft belt sleeve are then built; the coiling machine establishes a magnetic field in advance, so that the coiling machine outputs a specified torque at the speed of 0.
Specifically, the incoming material of the leveling machine is a steel coil which is fed off the bell-type furnace, the yield platform is not reduced, the strip steel incoming material has a plurality of folds, and the strip steel is easy to clamp when being worn, so that operators are required to pay attention to the incoming material plate type, and the incoming material plate type is smoothly passed. And the time for building the belt is needed to be well controlled, and the belt is needed to be built after being wrapped by the belt winding aid for one circle after the belt head and the sleeve notch are well aligned.
In addition, the smaller the sleeve speed is, the better the sleeve speed is, for example, 5mpm is selected, the positioning accuracy can be ensured, the coiling machine is required to properly establish a magnetic field in advance, and the larger torque can be output when the speed is 0, so that the positioning error is avoided, and an engineer can adjust the control method according to the actual condition of the site in the actual debugging process.
In summary, in the notch positioning logic control process of the present application, the notch area of the soft belt sleeve of the coiling machine is positioned to the appointed positionθAngular position, when the soft belt sleeve notched area of the coiling machine is from the specifiedθWhen the angle position reaches the overlapping position of the belt head, the belt head reaches the overlapping position on the coiling machine; in the threading cooperation logic control process, after the notch is positioned, the tape head is threaded according to the preset threading speed, when the tape head advances to reach the photoelectric switch on the threading guide plate in front of the coiling machine, the coiling machine is started, and when the tape head reaches the coiling machine, the tape head coincides with the notch opening area of the soft tape sleeve on the sleeve. When the winding aid contacts the belt head, controlling the winding machine to reach the belt threading speed; the length of the strip steel running track between the projection point of the photoelectric switch above the outlet strip threading guide plate on the strip steel and the biting gap of the wrapper is L; the time t for the tape head to walk within the distance L is greater than the time required for the coiler to start accelerating from 0 to the exit threading speed V. And in the time t, controlling the coiling machine to operate in a constant acceleration mode. According to the application, the belt head folds are pressed in the sleeve notch through accurate positioning, so that the problem of belt head indentation can be effectively solved, the indentation of the belt head of the strip steel on the inner layer of the steel coil is eliminated, and the quality and the yield of the strip are improved.
