In a cold-rolled steel strip processing line unit for continuous production, a coiler is arranged at an outlet section for coiling and forming the processed steel strip. A threading guide is usually provided in front of the coiler to support the steel strip tail and the threading head.
The steel strip drifting means that: the continuously produced steel strip needs to be cut and coiled at an outlet, and the residual steel strip after the steel strip is cut has no tension and is dragged on the guide plate until the coiler is completely coiled. The tape threading head means that: after the steel strip is cut off, the former coil is continuously wound, and the head of the latter steel strip is guided to another coiler for winding by devices such as a strip threading guide plate and the like. In the steel strip tail flicking and strip head guiding process, according to different coiling modes and coiling diameters, the swing position of the strip threading guide plate needs to be controlled to a preset position so as to support the strip steel to complete tail flicking and strip head threading. The traditional threading guide plate positioning mode is that a proximity switch sensor is installed at the stroke limit position of a piston rod of a hydraulic cylinder, when a control system sends an action signal to an electromagnetic valve, the piston rod stretches until the proximity switch sensor feeds back the position signal, and then the piston rod is kept locked. However, the positioning by the proximity switch sensor requires a preset stroke position, and is only applicable to the case of only one or two piston rod locking positions, namely, the case of only using the upper winding or the lower winding tape threading, and the function is relatively single. When the upper coiling and the lower coiling are simultaneously met and the threading guide plate needs to be used in the threading head and tail throwing stages, a plurality of piston rod locking positions need to be provided, and the situation that the positioning is difficult to realize only by a proximity switch sensor is met.

Detailed Description
The following describes in more detail embodiments of the present invention with reference to the schematic drawings. Advantages and features of the present invention will become apparent from the following description and claims. It is to be noted that the drawings are in a very simplified form and are not to precise scale, which is merely for the purpose of facilitating and distinctly claiming the embodiments of the present invention.
As shown in fig. 1, the present embodiment provides a strip steel coiling device, including a coiler 10, an inlet roller 20, a strip threading guide plate 30 and a hydraulic cylinder 40, where a vertical height of the inlet roller 10 is greater than a vertical height of the coiler 10, the strip threading guide plate 30 is located between the coiler 10 and the inlet roller 10, a first end of the strip threading guide plate 30 is hinged to a shaft head of the inlet roller 10, a piston rod of the hydraulic cylinder 40 is connected to a second end of the strip threading guide plate 30, so that the second end of the strip threading guide plate 30 swings relative to the first end of the strip threading guide plate 30, the piston rod of the hydraulic cylinder 40 is further provided with a position sensor 50, and the position sensor 50 is used for accurately positioning a target position of the strip threading guide plate 30.
Specifically, the coiler 10 is used for coiling strip steel, the inlet roller 10 is used for steering the strip steel and pinch the strip steel to the coiler 10 for coiling, and the strip steel is conveyed to the coiler 10 by the inlet roller 10. When the threading guide plate 30 is used for threading a strip head and drifting the strip steel, the head or the tail of the strip steel enters the coiler 10 through the threading guide plate 30, at this time, the swing angle of the threading guide plate 30 needs to be calculated according to the coiling type and the coiling diameter, the threading guide plate 30 is driven to swing through the hydraulic cylinder 40, and when the threading guide plate 30 swings to a target position, the position sensor 50 sends a signal and controls the hydraulic cylinder 40 to lock.
The hydraulic cylinder 40 is used for driving the second end of the threading guide plate 30 to rotate relative to the first end of the threading guide plate 30, and the swing angle of the threading guide plate 30 is controlled by controlling the telescopic length of a piston rod of the hydraulic cylinder 40. In this embodiment, the hydraulic cylinder 40 can use a proportional valve to realize stepless speed regulation, so as to accurately control a speed regulation curve and realize accurate positioning of the threading guide plate 30.
A piston rod of the hydraulic cylinder 40 is provided with a position sensor 50, and the position sensor 50 is used for realizing accurate positioning of the target position of the threading guide plate 30. The position sensor 50 can feed back the position of the piston rod in real time, so that the swing angle of the threading guide plate 30 can be accurately positioned, and the requirements of a plurality of locking positions can be met. In this embodiment, the position sensor 50 is a pull rope position sensor 50, and the pull rope position sensor 50 is also called a pull rope sensor, a pull rope electronic ruler, and a pull rope encoder. Specifically, the pull rope position sensor 50 may be mounted on the cylinder body, and the pull rope may be attached to the piston rod, and the linear movement of the pull rope is aligned with the extending and retracting direction of the piston rod due to the axial extension or contraction of the piston rod of the hydraulic cylinder 40. When the piston rod is extended or shortened, the pull rope position sensor 50 outputs an electric signal proportional to the movement distance of the pull rope, and the displacement, direction or speed of the piston rod can be obtained through the electric signal, so that the accurate positioning of the threading guide plate 30 is realized.
Optionally, the strip steel coiling apparatus further comprises a control system (not shown), the control system is electrically connected with the pull rope position sensor 50 and the hydraulic cylinder 40, and the control system receives position information fed back by the pull rope position sensor 50 and controls the hydraulic cylinder 40 to operate, in this embodiment, the control system is an editable logic controller (P L C). according to the coiling type and the coil diameter, the editable logic controller (P L C) is used for calculating the stroke of the hydraulic cylinder 40, and then controlling the hydraulic cylinder 40 to operate so that the strip threading guide plate 30 reaches a target position, as shown in fig. 1, the target position is, for example, the position S1 of the strip threading guide plate 30 when the strip steel is coiled at the tail, the position S2 of the strip threading guide plate 30 when the strip steel is coiled at the head, the position S3 of the strip threading guide plate 30 when the strip steel is coiled at the tail, and the position S4 of the strip threading guide plate 30 when the strip steel is coiled at the head.
When the coiling of one coiler is about to finish, the coiler slows down to the shearing speed, each press roll on the strip steel conveying path is pressed down, the threading guide plate 30 utilizes an editable logic controller (P L C) to calculate the stroke of a hydraulic cylinder 40, namely the angle of the threading guide plate 30 needing to swing according to the coiling type and the coiling diameter, then the hydraulic cylinder 40 is controlled to act, a stay wire displacement encoder feeds back the actual stroke, the threading guide plate 30 is ready to swing to a preset position, then a flying shear cuts off a continuous steel strip, the front steel strip at the cutting opening enters a tail throwing mode, the rear steel strip at the cutting opening enters a threading head mode after a waste plate and a sampling plate are cut off, the steel strip is ready to enter another coiler, at the moment, the other coiler finishes various coiling preparations, waits for the entry of a strip head, the threading guide plate 30 calculates the stroke of the hydraulic cylinder 40, namely the angle of the guide plate needing to swing according to the coiling type and the coiling diameter, controls the action of the hydraulic cylinder 40 and the stay wire displacement encoder to feed back the actual coiling position, and the coiling guide plate 30 is ready to swing according to the coiling position.
Referring to fig. 2, fig. 2 is a schematic structural diagram of a threading guide 30 according to an embodiment of the present invention, wherein a plurality of grooves 310 are formed on an upper surface of the threading guide 30 along a strip steel conveying direction. Because the prior process needs to coat the anti-rust oil on the steel belt, the oil amount is small or large according to the steel type, and the situation that the anti-rust oil adheres the belt head which passes through to the belt passing guide plate 30 easily occurs when the belt head passes through, so that the steel belt is arched and the belt passing is not favorable. The strip-shaped groove 310 can effectively prevent the tape head from being adhered to the tape threading guide plate 30 by the anti-rust oil when the tape head is threaded, so as to facilitate threading of the tape head. In this embodiment, the strip-shaped groove 310 is a shallow groove, the width of the groove is about 20 to 30mm, and the depth of the groove is about 7 to 10mm, and the strip-shaped groove 310 is arranged along the conveying direction of the strip steel (i.e., the length direction of the strip threading guide plate 30).
Optionally, the strip-shaped grooves 310 are distributed on the upper surface of the threading guide plate 30 at equal intervals. In this embodiment, the number of the strip-shaped grooves 310 is 5, and the grooves are equidistantly arranged on the upper surface of the threading guide plate 30 to better contain the anti-rust oil falling from the steel belt and prevent the steel belt from arching. It should be understood that the number of the strip-shaped grooves 310 may be more than 5, or less than five, and may be selected according to the width of the steel strip and the coiling condition, which is not limited in this application. Similarly, the shape of the stripe groove 310 may also be a circle or other shapes, and the distribution mode may be a uniform distribution, such as an array distribution or a ring distribution, and may also be a non-uniform distribution, which is not limited in this application.
With continued reference to fig. 2, the threading guide 30 has at least one accommodating cavity, and the electromagnet 320 is accommodated in the accommodating cavity. When the tail of the steel strip is thrown, the steel strip at the tail part loses tension, the last section of the steel strip with the length of 2-3 meters is in a free state after leaving auxiliary equipment such as an inlet roller 10 and the like, and the steel strip can slide and stack before entering the coiling due to the fact that the installation elevation of a coiling machine is generally lower than the advancing elevation of the steel strip, so that the steel strip is coiled and stacked. The electromagnet 320 absorbs the steel belt at the tail part, so that the steel belt is dragged on the belt penetrating guide plate 30 to prevent the steel belt from sliding off to cause steel piling. In the embodiment, the electromagnet 320 can adjust the electromagnetic intensity steplessly, can be set on the HMI of the machine set, and has obvious effect on the thin steel strip. During specific production, along with the continuation of coiling and coiling, the tail of the front-section steel belt passes through the last compression roller, after a grating ruler arranged at the position detects the tail of the belt, a signal is given to the tail of the belt to pass through, the electromagnet 320 is electrified to suck the tail of the belt to drag the belt, and the electromagnet 320 is powered off until the coiling of the tail of the belt is finished, the work is finished, and the belt threading guide plate 30 is reset.
In this embodiment, the electromagnets 320 are strip-shaped and arranged along the conveying direction of the strip steel (i.e., the length direction of the strip steel). It should be appreciated that the width of the working surface of the electromagnet 320 covers the widest and narrowest limit gauge strip to improve the versatility of the threading guide 30. In this embodiment, the electromagnets 320 are 2 pieces, and are disposed on two sides of the threading guide 30 along the length direction of the threading guide 30. Of course, the present application does not impose any limitation on the number of electromagnets 320. In addition, the electromagnet 320 may also be in other shapes, such as a sheet shape, which is not limited in this application.
Optionally, the accommodating cavity is located in the threading guide plate 30 or extends from the threading guide plate 30 to the upper surface of the threading guide plate 30 so as to facilitate smooth passing of the steel strip. In this embodiment, the accommodating cavity is located in the threading guide 30, which is equivalent to the electromagnet 320 being located in the threading guide 30 and adsorbing the steel strip through the threading guide 30, so that the surface of the steel strip is not easily scratched.
In this embodiment, the threading guide plate 30 is made of a high polymer wear-resistant material, and has a long service life and is not easy to scratch the surface of the strip steel. Meanwhile, the tape threading guide plate 30 does not affect the adsorption effect of the electromagnet 320.
In this embodiment, the second end of the threading guide 30 is further provided with a retractable portion, and the retractable portion is extended or shortened by a hydraulic cylinder arranged in the threading guide 30, so that the second end of the threading guide 30 is close to the winding machine, thereby facilitating threading of the tape head and winding of the tape tail.
In summary, the invention provides a strip steel coiling device, which comprises a coiling machine, an inlet roller, a strip threading guide plate and a hydraulic cylinder, wherein the vertical height of the inlet roller is greater than that of the coiling machine, the strip threading guide plate is positioned between the coiling machine and the inlet roller, the first end of the strip threading guide plate is hinged to a shaft head of the inlet roller, a piston rod of the hydraulic cylinder is connected with the second end of the strip threading guide plate so that the second end of the strip threading guide plate swings relative to the first end of the strip threading guide plate, and a position sensor is further arranged on the piston rod of the hydraulic cylinder and used for accurately positioning the target position of the strip threading guide plate.
