For the purpose of making the objects, technical solutions and advantages of the present invention more apparent, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention, and it is apparent that the described embodiments are only some embodiments of the present invention, not all embodiments of the present invention. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
Some embodiments of the present application will be described in detail below with reference to the accompanying drawings. The following embodiments and features of the embodiments may be combined with each other without conflict.
Referring to fig. 1, a flow diagram of a method of preventing steel piling according to one embodiment of the present application is shown.
As shown in fig. 1, a method for preventing steel from piling up is shown, which specifically includes steps S100 to S200.
Step S100, acquiring a position measurement value of an upper pinch roll in a pinch roll set in the process of feeding strip steel into a coiling machine by using the pinch roll set, and adjusting the position of the upper pinch roll until a first roll gap meets a set value when the position measurement value of the upper pinch roll jumps; the first roll gap refers to a gap between the upper pinch roll and the lower pinch roll.
The pinch roll set is used in initial winding stage to bend the head of strip near the mandrel of the winding machine and to produce tension between the final stand and the pinch roll. The pinch roll set comprises an upper pinch roll and a lower pinch roll, and a gap for passing strip steel is reserved between the upper pinch roll and the lower pinch roll; the operation side and the driving side of the upper pinch roll are respectively provided with a hydraulic cylinder, and the hydraulic cylinders control the lifting of the upper pinch roll; displacement sensors are arranged in the two hydraulic cylinders and are used for detecting the positions of the upper pinch rolls; the detected displacement is transmitted to a digital control system, and after the numerical control system determines the roll gap value between the upper pinch roll and the lower pinch roll, a downward command is issued to control the hydraulic cylinder to move the upper pinch roll until the roll gap between the upper pinch roll and the lower pinch roll meets the calculated value.
It can be understood that the measured value of the position of the upper pinch roll is one of the calculated parameters of the actual value of the first roll gap, if the measured value jumps, the corresponding actual value of the first roll gap will also change, thereby affecting that the actual value of the first roll gap cannot meet the set value, and causing the abnormal operation of the pinch roll set, so that in order to avoid the situation, when the measured value of the position of the upper pinch roll jumps, the measured value of the position is not used for adjusting the first roll gap any more, but the position of the upper pinch roll is directly adjusted.
In some possible embodiments, based on the foregoing, the obtaining the position measurement of the upper pinch roll in the pinch roll set during the feeding of the strip into the coiler with the pinch roll set includes:
before strip steel enters a pinch roll set, acquiring a first position measurement value when an upper pinch roll is at a pre-swing position;
and after the strip steel enters the pinch roll set, acquiring a second position measured value of the upper pinch roll when the pinch roll set is in a lifting mode.
The pre-swinging position is the position of the upper pinch roll just convenient for the strip steel to enter the pinch roll group; the lifting mode of the pinch roll set is used for facilitating strip steel to be separated from the pinch roll set, and when the pinch roll set is in the lifting mode, a roll gap between the upper pinch roll and the lower pinch roll is enlarged.
In some possible embodiments, based on the foregoing solutions, when the position measurement value of the upper pinch roll hops, adjusting the position of the upper pinch roll until the first roll gap meets the set value includes:
when the first position measured value of the upper pinch roll jumps, the position of the upper pinch roll is adjusted until the first roll gap meets a first set value;
when the measured value of the second position of the upper pinch roll jumps, the position of the upper pinch roll is adjusted until the first roll gap meets a second set value;
the first set value refers to an actual value of the first roll gap when the upper pinch roll is in the pre-swing position, and the second set value refers to an actual value of the first roll gap when the pinch roll set is in the lifting mode.
It can be understood that the actual value of the first roll gap is the distance value between the upper pinch roll and the lower pinch roll, the first set value is used for enabling the strip steel to enter the pinch roll set, when the first roll gap is in the first set value, the strip steel just can enter the first roll gap, the second set value is used for enabling the strip steel to leave the pinch roll set, and when the first roll gap is in the second set value, the strip steel processed by the pinch roll set just can leave from the first roll gap.
When the upper pinch roll is positioned at the pre-swing position, the actual value of the first roll gap just meets a first set value, if the measured value of the upper pinch roll at the pre-swing position jumps, the actual value of the first roll gap obtained by the measured value of the first position changes, the first roll gap cannot meet the first set value, and strip steel cannot enter the pinch roll set, so that in order to avoid the situation, when the measured value of the upper pinch roll at the pre-swing position jumps, the position of the upper pinch roll is directly adjusted, and the first roll gap is ensured to meet the first set value.
When the pinch roll set is in the lifting mode, the actual value of the first roll gap just meets a second set value, if the second position measured value of the upper pinch roll when the pinch roll set is in the lifting mode jumps, the actual value of the first roll gap calculated by the second position measured value can be changed, the first roll gap can not meet the second set value, and the strip steel can not be separated from the pinch roll set, so that in order to avoid the situation, when the second position measured value of the upper pinch roll when the pinch roll set is in the lifting mode jumps, the position of the upper pinch roll is directly adjusted, and the first roll gap is ensured to meet the second set value.
The two sides of the upper pinch roll are respectively provided with a hydraulic cylinder used for lifting, after the first position measurement value or the second position measurement value jumps, the position of the upper pinch roll is not regulated by the hydraulic cylinders controlled by the digital control system, and the position of the upper pinch roll is regulated by the hydraulic cylinders directly, so that the phenomenon of steel piling of the pinch roll set caused by an error control instruction sent by the fact that the digital control system calculates an error roll gap value is avoided.
In some possible embodiments, based on the foregoing, the first setting value is calculated according to a thickness of the clamped strip steel.
It will be appreciated that the first set point is to ensure that the strip can enter the first gap and be clamped by the upper and lower pinch rolls for processing, so the first gap should be greater than or equal to the strip thickness.
In some possible embodiments, based on the foregoing scheme, further comprising:
and when the first roll gap does not meet the first set value, sending out a signal for prohibiting steel feeding.
It can be understood that when the first roll gap does not meet the first set value, the roll gap is smaller than the thickness of the strip steel, and the strip steel cannot enter the pinch roll set, so that a signal for prohibiting steel feeding needs to be given, and the phenomenon of steel piling is prevented.
With continued reference to fig. 1, step S200 is to obtain a position measurement value of the auxiliary winding roller during the process of winding the strip steel by using the auxiliary winding roller to assist the coiler, and adjust the position of the auxiliary winding roller until the second roll gap meets a set value when the position measurement value of the auxiliary winding roller jumps; the second roll gap is a gap between the auxiliary roll and the mandrel of the coiling machine.
The auxiliary winding roller is used for guiding the head of the strip steel to enter the coiling machine and then firmly winding the core shaft, the core shaft is pre-expanded when the head of the strip steel enters the coiling machine, and friction and effective connection are established between the core shaft and the strip steel with the aid of the auxiliary winding roller. The auxiliary winding roller is provided with a hydraulic cylinder, a displacement sensor is arranged in the hydraulic cylinder and used for detecting the displacement of the auxiliary winding roller, and the detected displacement is uploaded to the digital control system.
It can be understood that the measured value of the position of the auxiliary winding roller is one of the calculated parameters of the second roll gap, the obtained measured value of the position is transmitted to the digital control system and then calculated to obtain the actual value of the second roll gap, and then the digital control system issues instructions to adjust the position of the auxiliary winding roller until the second roll gap meets the calculated actual value. If the position measured value of the auxiliary winding roller jumps, the calculated actual value of the second roll gap is deviated, so that the second roll gap cannot meet the set value, the opening degree of the second roll gap is insufficient, the head of the strip steel cannot be wound by the winding machine, and the situation of steel piling occurs. Therefore, in order to avoid the situation, when the position measured value of the auxiliary winding roller jumps, the actual value of the second roll gap is not calculated by using the position measured value, and then the adjustment is carried out, but the position of the auxiliary winding roller is directly adjusted to ensure that the second roll gap can meet the set value.
In some possible embodiments, based on the foregoing, the obtaining the position measurement value of the auxiliary winding roller during the strip winding by the auxiliary winding machine includes:
when the strip steel is coiled by the auxiliary roller, a first position measured value of the auxiliary roller at a pre-swinging position is obtained;
and during the process of coiling the strip steel by the coiling machine, acquiring a second position measured value when the auxiliary roller is farthest from the mandrel of the coiling machine.
It should be noted that the pre-swing position of the auxiliary winding roller refers to the position of the auxiliary winding roller when the strip steel just can enter the second roll gap.
In the process of coiling the strip steel by the coiling machine, after the strip steel is coiled on the mandrel of the coiling machine for a preset number of turns, the auxiliary winding roller is opened to the position farthest from the mandrel, so that the influence on the subsequent coiling of the strip steel is avoided.
In some possible embodiments, based on the foregoing solution, when the measured value of the position of the auxiliary roll jumps, adjusting the position of the auxiliary roll until the second roll gap meets the set value includes:
when the first position measured value of the auxiliary winding roller jumps, the position of the auxiliary winding roller is adjusted until the second roller gap meets a first set value;
when the measured value of the second position of the auxiliary winding roller jumps, the position of the auxiliary winding roller is adjusted until the second roller gap meets a second set value;
the first set value refers to an actual value of a second roll gap when the auxiliary roll is at a pre-swing position, and the second set value refers to an actual value of the second roll gap when the auxiliary roll is farthest from a mandrel of the coiling machine.
It can be understood that the actual value of the second roll gap is the distance value between the auxiliary roll and the mandrel of the coiling machine, when the auxiliary roll is at the pre-swing position, the actual value of the second roll gap just meets the first set value, if the measured value of the auxiliary roll at the pre-swing position jumps, the actual value of the second roll gap calculated by the measured value of the first position changes, and the second roll gap cannot meet the first set value, so that the head of strip steel cannot enter the coiling machine for coiling, and in order to avoid the situation, when the measured value of the auxiliary roll at the pre-swing position jumps, the position of the auxiliary roll is directly adjusted, and the second roll gap is ensured to meet the first set value.
When the auxiliary winding roller is farthest from the winding machine mandrel, the actual value of the second roll gap just meets a second set value, if the auxiliary winding roller jumps at the position measured value farthest from the winding machine mandrel, the actual value of the second roll gap calculated by the second position measured value can be changed, so that the second roll gap cannot meet the second set value, after the strip steel is wound for a certain number of turns, the auxiliary winding roller is not far away from the winding mandrel, and the auxiliary winding roller affects the subsequent winding of the strip steel, so that in order to avoid the situation, when the auxiliary winding roller jumps at the position measured value farthest from the winding machine mandrel, the position of the auxiliary winding roller is directly adjusted, and the second roll gap is ensured to meet the second set value.
In some possible embodiments, based on the foregoing, the first set point is calculated from the thickness of the coiled strip steel.
It will be appreciated that the first set point is to ensure that the strip can enter the second gap and be gripped by the wrapper roll and the coiler mandrel for coiling, so the second gap should be greater than or equal to the thickness of the strip.
