Detailed Description
For the purposes of making the objects, technical solutions and advantages of the embodiments of the present application more clear, the technical solutions of the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is apparent that the described embodiments are some embodiments of the present application, but not all embodiments. All other embodiments, which can be made by one of ordinary skill in the art without undue burden from the present disclosure, are within the scope of the present disclosure.
Referring to fig. 1, fig. 1 is a flowchart of a coiler control method according to an embodiment of the present application.
The specific steps may include:
s101: detecting the working state of the winding drum;
the winding machine comprises a winding drum and a side guide plate, wherein the winding drum is used for winding a winding object into a coil, and the side guide plate is used for guiding the winding object into the winding drum and ensuring that the edge of the winding object after winding is tidy. The winding target may be a strip-shaped product such as a steel strip, an iron strip, an aluminum strip, a plastic strip, a paper strip, or the like, which is required to perform a winding operation, and is not particularly limited herein.
The operating state of the spool may include a loaded state, which means a state in which the winding object has entered the spool, and an unloaded state, which means a state in which the winding object has not entered the spool. The embodiment can realize detection of the working state of the winding drum based on equipment such as a pressure sensor, a light sensor, a distance sensor and the like.
S102: if the working state of the winding drum is a loaded state, controlling a hydraulic cylinder corresponding to the side guide plate to enter a pressure ring control mode so that the side guide plate clamps a coiling object;
the step is based on the fact that the winding drum is in a loaded state, and at the moment, the corresponding hydraulic cylinders of the side guide plates can be controlled to enter a pressure ring control mode, so that the side guide plates clamp the edge of a winding object in the pressure ring control mode.
S103: detecting the coiling width of the coiling object, and calculating a locking trigger value according to the coiling width and the anti-flanging coefficient;
the present embodiment can detect a winding width of a winding object, which is a width of the winding object in a direction perpendicular to a winding direction; after the winding width is obtained, the product of the winding width and the anti-hemming coefficient can be used as a locking trigger value.
The above-mentioned anti-hemming coefficient may be a parameter input by a user on the coiler, or may be a parameter determined by the coiler according to the product model of the coiling object. Specifically, the anti-flanging coefficient is related to parameters such as thickness, material type, shape and the like of the coiling object, and the embodiment can determine the anti-flanging coefficient corresponding to each product model based on the parameters.
S104: judging whether the current stroke length of the side guide plate is larger than or equal to a locking trigger value or not; if yes, go to S105; if not, ending the flow;
there may be an operation of acquiring the stroke length of the side guide at a preset cycle before this step, and the stroke length acquired at the current cycle may be taken as the current stroke length of the side guide. In this step, the current stroke length is compared with the locking trigger value, and if the current stroke length is greater than or equal to the locking trigger value, it is indicated that the phenomenon that the cross section of the winding object is arched or the edge portion bulges due to insufficient rigidity in the width direction of the winding object may occur in the current state, so that the related operation of S105 may be performed. If the current stroke length is smaller than the locking trigger value, the operation can be ended; as a possible implementation manner, if the current stroke length is smaller than the locking trigger value, the step of determining whether the current stroke length of the side guide plate is greater than or equal to the locking trigger value in S104 may be re-entered after the delay for a preset period of time, so as to realize the periodic determination of the current stroke length of the side guide plate.
S105: and controlling the hydraulic cylinders corresponding to the side guide plates to exit the pressure ring control mode, and locking the positions of the side guide plates.
The step is based on that the current stroke length of the side guide plate is greater than or equal to the locking trigger value, and in order to avoid the flanging phenomenon in the coiling process, the hydraulic cylinders corresponding to the side guide plate can be controlled to exit the pressure ring control mode, and the positions of the side guide plates are locked, so that the stroke length of the side guide plate is not increased any more until the current operation of the coiling machine is completed.
In the embodiment, after the winding drum is in the loaded state, the hydraulic cylinders corresponding to the side guide plates are controlled to enter a pressure ring control mode, so that the side guide plates clamp the edge of a winding object. In this embodiment, the locking trigger value is calculated according to the winding width and the anti-hemming coefficient of the winding object, and when the stroke length of the side guide is greater than or equal to the locking trigger value, the phenomenon that the cross section of the winding object is arched or the edge portion bulges due to insufficient rigidity in the width direction of the winding object will occur. In the embodiment, after the current stroke length of the side guide plate is greater than or equal to the locking trigger value, the pressure ring control mode is exited and the position of the side guide plate is locked, so that the phenomenon that the side guide plate cannot reach the set target pressure value all the time and is continuously clamped inwards can be effectively avoided. Therefore, the embodiment can avoid the phenomenon of flanging in the coiling process and improve the control precision of the coiling machine.
As a further description of the corresponding embodiment of fig. 1, this embodiment may provide a pressure sensor on the spool, and accordingly, the operational status of the spool may be determined by: acquiring a pressure value of the pressure sensor, and determining the working state of the winding drum according to the pressure value; when the pressure value is larger than a preset value, the working state of the winding drum is a loading state; and when the pressure value is smaller than or equal to a preset value, the working state of the winding drum is an idle state.
As a further introduction to the corresponding embodiment of fig. 1, the corresponding relation between each product model and the anti-hemming coefficient may be stored in advance in the coiler, and the anti-hemming coefficient corresponding to the product model of the coiling object is selected according to the corresponding relation before the locking trigger value is calculated according to the coiling width and the anti-hemming coefficient.
As a further introduction to the corresponding embodiment of fig. 1, after locking the position of the side guide, the stroke length of the guide will not be changed any more, so that the coiler performs the coiling operation with the side guide in the locked position. When the coiling operation is completed, the coiling object is completely separated from the reel, and the stroke length of the side guide plate can be changed so as to execute the next coiling operation. Therefore, after the position of the side guide plate is locked, the working state of the winding drum can be judged whether to be an idle state or not; if yes, unlocking the position of the side guide plate; if not, continuing to lock the position of the side guide plate.
As a further introduction to the corresponding embodiment of FIG. 1, before determining whether the current stroke length of the side guide is greater than or equal to the locking trigger value, a magnetic scale stroke value of a hydraulic cylinder corresponding to the side guide may also be obtained, and the current stroke length of the side guide may be determined according to the magnetic scale stroke value. The stroke value of the magnetic ruler is the absolute value of subtracting the zero position from the current position of the magnetic ruler of the hydraulic cylinder.
As a further introduction to the corresponding embodiment of FIG. 1, the coiler further includes an operator display for displaying and inputting the anti-hemming factor and for selecting the on-line or off-line pressure ring control locking function so that the coiler pressure ring control locking function is also controlled to be on-line prior to detecting the operational condition of the coiler drum.
The flow described in the above embodiment will be described below by the scheme of preventing the hot rolled steel strip from folding in the hot rolled steel strip production line.
In a hot rolled steel strip production line, after the rolling production is finished, the steel strip enters a coiling machine for coiling, and a side guide plate of the coiling machine is used as a part of the coiling machine, and the side guide plate is mainly used for guiding the head of the steel strip to enter a coiling drum of the coiling machine and clamping the edge of the steel strip after the head of the steel strip enters the coiling drum so as to ensure that the edge of the coiled steel strip is neat. Referring to fig. 2 and 3, fig. 2 is a schematic diagram illustrating a process of collecting a steel strip by a coiler in a process of producing and coiling the steel strip according to an embodiment of the present application, and fig. 3 is a schematic diagram illustrating a control form of the steel strip and a side guide according to an embodiment of the present application. In the figure, 1 represents a steel strip, 2 represents a coiler side guide, 3 represents a coiler drum, 4 represents a width gauge, 5 represents a side guide hydraulic cylinder, and the rolling direction of the steel strip and the clamping direction of the side guide are also shown. After the rolling of the hot rolled steel strip is completed, it is collected into coils through a coiler as shown in fig. 2. As shown in FIG. 3, the head of the hot rolled steel strip is guided by side guide plates, and the side guide plates on two sides are driven by hydraulic cylinders to clamp the side surfaces of the steel strip.
The control mode of the side guide plate of the coiling machine is generally divided into two sections of control, wherein the first section of control is that before the head of the steel strip enters the coiling drum, the side guide plate is in a position loop control mode, namely the side guide plate is positioned according to the width specification of the steel strip to guide the head of the steel strip; the second section of control is that after the head of the steel belt enters the winding drum, the side guide plates are in a pressure ring control mode, namely, the side guide plates clamp the steel belt inwards at the moment, and the oil pressure sensors of the hydraulic cylinders of the side guide plates are kept at a set constant pressure value all the time, so that the edge parts of the steel belt are clamped dynamically.
In the actual production process of the steel belt with the extremely thin specification, when the side guide plates clamp the edge part of the steel belt in the state of a pressure ring, the phenomenon that the side guide plates are continuously clamped inwards due to the fact that the rigidity of the steel belt in the width direction is insufficient occurs, the cross section of the steel belt is arched or the edge part is raised because the side guide plates are not up to a set target pressure value, the edge folding defect of the steel belt is caused, and when the side guide plates squeeze the edge part of the steel belt to be heavier, the steel belt rolling and breaking steel piling accident can occur, so that the product quality and the production smooth operation are seriously influenced. Referring to fig. 4, fig. 4 is a schematic view of a steel strip with a cross-sectional direction pressed and raised by a side guide according to an embodiment of the present application. As shown in fig. 4, when a thin steel strip is produced, edge bulging is likely to occur during clamping of the side guide plates due to insufficient rigidity in the cross section direction of the steel strip, edge folding defects are caused, the clamping direction of the side guide plates is also shown, 1 represents the steel strip, and 5 represents the corresponding hydraulic cylinder of the side guide plates.
In order to solve the technical problems in the related art, the present embodiment provides a solution for preventing hot rolled steel strip from flanging. The coiling machine applied to the scheme comprises: the device comprises a width gauge, a control unit, a coiling machine side guide hydraulic cylinder, a coiling machine coiling drum pressure sensor and an operation display screen; the control unit is respectively connected with the width gauge, the coiling machine side guide plate hydraulic cylinder, the coiling machine winding drum and the operation display screen.
Specifically, the width gauge is used for sending the actual width information of the steel strip to the control unit. The control unit is used for reading the width information of the steel belt of the width measuring instrument, calculating a side guide plate locking trigger value X according to the anti-flanging coefficient input by the operation display screen, reading the stroke value Y of the side guide plate hydraulic cylinder, and sending an instruction to the side guide plate hydraulic cylinder according to the comparison result of the two values. The coiler side guide plate hydraulic cylinder is provided with a displacement sensor and an oil pressure sensor and is used for sending the stroke value of the side guide plate to the control unit and simultaneously used as an actuating mechanism for realizing the functions of side guide plate pressure ring control, side guide plate position locking and the like according to the command issued by the control unit. The coiler drum is provided with a pressure sensor for judging the position of the head of the steel strip and is used as a trigger signal for the control unit to judge the opening pressure control ring of the side guide plate. The operation display screen is used for displaying and inputting the anti-flanging coefficient, and selecting the pressure control locking function for use or disabling.
Referring to fig. 5, fig. 5 is a schematic diagram of an input interface of function commission and anti-hemming coefficients in an operation display screen according to an embodiment of the present application. An operator can select an ON state for controlling a locking function of a pressure ring of a side guide plate of a coiling machine, the head of a steel belt enters a coiling drum of the coiling machine, the side guide plate of the coiling machine enters the pressure ring control state, at the moment, a control unit receives steel belt width information L provided by a width measuring instrument and reads an anti-flanging coefficient x% (such as 0.8%) input by the operator in an operation display screen in a diagram six, so that a locking trigger value X=Lx%; at this time, the control unit reads the stroke value Y of the hydraulic cylinder of the side guide plate according to a certain period T and compares the stroke value Y with the trigger value, when X is less than or equal to Y, the steel belt is considered to have higher risk, the edge folding defect shown in fig. 4 appears, the control unit sends out an instruction to enable the side guide plate to withdraw from the pressure ring for control and position locking, and the current clamping state is maintained until the coiling of the steel belt is finished. When X > Y, the risk of edge folding of the steel belt is considered to be low, the control of the side guide plate pressure ring is kept, and the judgment of the value Y and the trigger value X is continued until X is less than or equal to Y locking or the coiling of the steel belt is finished. In the embodiment, a pressure control ring locking function is added in a guide plate control module at the front side of a coiling machine of a hot-rolled strip steel production line, a folding-preventing control coefficient function block is arranged, and program module links are made. When the strip steel bites into the coiling machine and the side guide plate is in the pressure ring control mode by using the pressure control ring locking function, and when the magnetic scale detects that the displacement Y of the side guide plate exceeds the anti-flanging control coefficient, the side guide plate exits from the pressure ring control and performs position locking, so that the flanging problem caused by excessive extrusion of the strip steel edge due to the stroke of the side guide plate is prevented, and the strip steel edge quality assurance capability and the production stability of hot rolled strip steel are improved.
Referring to fig. 6, fig. 6 is a flowchart of a method for preventing hot rolled steel strip edge folding according to an embodiment of the present application, which specifically includes the following operations:
step one: the pressure control locking function in the operation display screen is in a commissioning state.
Step two: when the coiler drum pressure sensor is in a loaded state, the control unit judges that the head of the steel belt enters the drum and sends out a first instruction to control the coiler side guide plate hydraulic cylinder to enter the pressure control ring for control.
Step three: the control unit reads the actual width value L of the steel belt transmitted by the production line width gauge and the anti-flanging control coefficient x% input in the operation display screen, and calculates a side guide plate locking trigger value X=L x%.
Step four: the control unit reads the stroke value Y of the magnetic scale of the side guide plate hydraulic cylinder according to a certain time period T; y ε { Y1, Y2, … …, yn }; Y1-Yn are absolute values of subtracting zero positions from the current positions of the hydraulic cylinders in each period.
Step five: the control unit sequentially compares Y acquired in each period with the locking trigger value X in value.
Step six: and when X > Y, the control unit returns to the step four until the reel pressure sensor is in an empty state, and the control unit judges that the steel belt leaves the reel to finish coiling operation, and the control flow is ended.
