Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that the process, method, article or equipment including a series of elements includes not only those elements, but also includes other elements not explicitly listed, or also includes elements inherent to such process, method, article or equipment.

The term "more than two" includes two or more than two situations.

[0038] During the production process of strip steel, it is necessary to perform straightening and trimming. Straightening of strip steel refers to the uniform plastic stretching of steel to straighten the steel into the required strip steel. Trimming of strip steel refers to cutting the strip steel to make it into the required shape after trimming.

[0039] In the process of straightening and trimming the strip, the straightening and trimming processes can be performed by the straightening and trimming system or the straightening and trimming unit. The system can perform the straightening and trimming processes of the strip respectively. The straightening and trimming system can be divided into a straightening mode and a trimming mode. In the straightening mode, the straightening and trimming system performs the straightening process of the strip, and in the trimming mode, the straightening and trimming system performs the trimming process of the strip.

[0040] In related technologies, such as Figure 1 As shown, the straightening and trimming system includes an inlet pinch roller 11, an inlet tension roller 12, a straightening actuator 13, a trimming actuator 14, an outlet tension roller 15, and an outlet pinch roller 16. In the straightening mode, the inlet pinch roller 11 and the outlet pinch roller 16 fix the strip, the inlet tension roller 12 and the outlet tension roller 15 apply tension to the strip, and the straightening actuator 13 is used to straighten the strip uniformly. In the trimming mode, the inlet pinch roller 11, the inlet tension roller 12, the outlet tension roller 13, and the outlet pinch roller 14 fix the strip, and the trimming actuator 15 is used to cut the strip.

[0041] In the trimming mode, the strip is wrapped by the inlet tension roller 12 and the outlet tension roller 13 during the process of passing through the inlet tension roller 12 and the outlet tension roller 13, and the strip is bent for many times. During the bending process, the bending degree of the strip is relatively high. When the strip is trimmed by the trimming actuator 14, the strip is easily broken due to the multiple bendings. Especially when the brittleness of the strip is high and the toughness of the strip is poor, the vibration during trimming is likely to cause the strip to break. In addition, in the trimming mode, the inlet pinch roller 11 and the outlet pinch roller 16 play the same role as the inlet tension roller 12 and the outlet pinch roller 15. On this basis, the inlet pinch roller 12 and the outlet pinch roller 13 need to be connected to the power supply when they are in operation, resulting in a waste of electric energy.

[0042] In order to solve the technical problem that the strip steel is easily broken due to multiple bending during processing, the present application discloses a straightening and trimming system, such as Figure 2 As shown, it includes a first unit 21 and a second unit 22, the first unit 21 is used for straightening the strip steel, and the second unit 22 is used for trimming the strip steel;

[0043] The first unit 21 includes: an inlet pinch roller 211, an inlet tension roller 212, a tensioning actuator 213, an outlet tension roller 214 and an outlet pinch roller 215 which are arranged in sequence along the strip transmission direction;

[0044] The second unit 22 includes: an entrance pinch roller 211, a first guide plate 216, a trimming actuator 217, a second guide plate 218 and an exit pinch roller 215 arranged in sequence along the strip transmission direction, wherein the bending degree of the strip 216 when passing through the first guide plate is smaller than the bending degree of the strip when passing through the entrance tension roller 212, and the bending degree of the strip when passing through the second guide plate 218 is smaller than the bending degree of the strip when passing through the exit tension roller 214.

[0045] In order to solve the technical problem that the strip steel is easily broken when being trimmed by the trimming actuator due to multiple bending when the strip steel is trimmed by the trimming system, two sets of units are designed respectively. The two sets are used for the strip steel trimming and the strip steel trimming.

[0046] When the straightening and trimming system performs the straightening function on the strip, the straightening and trimming system activates the straightening mode, and the strip is conveyed to the first unit 21 through the entrance pinch roller 211. The entrance tension roller 212 and the exit tension roller 214 respectively change the tension value of the strip in the entrance pinch roller 211 and the exit pinch roller 215. The straightening actuator 213 between the entrance tension roller 212 and the exit tension roller 214 performs the straightening of the strip, and the straightened strip is transmitted from the exit pinch roller 215 out of the first unit.

[0047] When the straightening and trimming system performs the trimming function of the strip, the straightening and trimming system activates the trimming mode, and the strip is transported to the second unit through the entrance pinch roller 211 for trimming, and the trimmed strip is transmitted out of the first unit through the exit pinch roller 215. When the strip is transmitted between the entrance pinch roller 211 and the exit pinch roller 215, the second unit also includes a first guide plate 216, a trimming actuator 217, and a second guide plate 218. The first guide plate 216 transmits the strip input by the entrance pinch roller 211 to the trimming actuator 217 for trimming, and transmits the trimmed strip from the trimming actuator 217 to the exit pinch roller 215 through the second guide plate 218.

[0048] Compared with the related art, in the technical solution of this embodiment, the strip steel is transmitted through the first guide plate 216 and the second guide plate 218 in the trimming mode. When the strip steel passes through the first guide plate 216 and the second guide plate 218, the bending degree of the strip steel is smaller than that of the strip steel transmitted through the inlet tension roller 212 and the outlet tension roller 214. For example, the first guide plate 216 and the second guide plate 218 can be as follows: Figure 2 The linear guide plate shown can also be Figure 3 The folding line guide shown. When the strip is trimmed by the trimming actuator, the strip is not bent multiple times, so the possibility of strip breakage is greatly reduced during trimming, ensuring the normal operation of the straightening and trimming system. At the same time, no additional devices that require power supply are added to the second unit, reducing the power consumption of the straightening and trimming system.

[0049] In one embodiment, either the first guide plate or the second guide plate includes: a plurality of rollers; a bracket, the bracket including a frame and a plurality of rotating shafts spaced between opposite sides of the frame, the rotating shafts being sleeved with rollers, and when the strip steel is transmitted to the upper surface of the rollers, the rollers rotate around the rotating shafts along the transmission direction of the strip steel.

[0050] The main functions of the first guide plate and the second guide plate are to transport the strip steel. The first guide plate transports the strip steel from the entrance pinch roller to the trimming actuator, and the trimming actuator performs trimming operations on the strip steel. The second guide plate transports the trimmed strip steel from the trimming actuator to the exit pinch roller. In the process of transporting the strip steel, in order to reduce the friction between the strip steel and the first guide plate or the second guide plate, this embodiment describes the structure of either the first guide plate or the second guide plate.

[0051] As shown in FIG. 4 , in FIG. 4 (a), the first guide plate or the second guide plate includes a roller 41 and a frame 42, and a plurality of rotating shafts are arranged at preset intervals between opposite sides of the frame, and the plurality of rotating shafts are arranged in parallel. The rollers 41 are respectively arranged on the rotating shafts 421, and the rollers 41 can rotate on the rotating shafts 421. In FIG. 4 (b), when the strip is transmitted on the first guide plate or the second guide plate, the strip is shown as 43 in FIG. 4 , and when it is transmitted from right to left, the rotation direction of the rollers 41 is shown in the figure, respectively, to realize the transmission of the strip on the first guide plate or the second guide plate, and reduce the friction between the strip and the first guide plate or the second guide plate.

[0052] In some embodiments, in a direction perpendicular to the transmission direction of the strip, a height value of the upper surface of the roller is greater than a height value of the upper surface of the frame.

[0053] When the steel strip is transmitted on the first guide plate or the second guide plate, in order to ensure that the steel strip can fully contact the roller, the embodiment further proposes a height value relationship between the roller and the frame. As shown in FIG4(b), the height value of the upper surface of the roller is h1, and the height value of the upper surface of the frame is h2. On the basis that the height value of the upper surface of the roller is higher than the height value of the upper surface of the frame, the steel strip can avoid contact with the frame and only contact with the roller, thereby reducing the probability of the steel strip being scratched.

[0054] In some embodiments, the first guide plate and the second guide plate are detachable guide plates; when trimming the strip, the first guide plate and the second guide plate are configured to be installed in the second unit; when tensioning and straightening the strip, the first guide plate and the second guide plate are configured to be moved out of the second unit.

[0055] Since the straightening and trimming system supports both the straightening mode and the trimming mode. In the straightening mode, the device that mainly performs the straightening action is the straightening actuator, while in the trimming mode, the device that mainly performs the trimming action is the trimming actuator. At the same time, in the straightening mode and the trimming mode, straightening or trimming is performed by different units of the straightening and trimming system. When the straightening and trimming system switches modes, the switching of the units also needs to be performed. When switching from the straightening mode to the trimming mode, the straightening and trimming system installs the first guide plate 216 and the second guide plate 218 between the entrance pinch roller 211 and the exit pinch roller 215, and installs the trimming actuator 217 between the first guide plate 216 and the second guide plate 218. At this time, the first guide plate 216 and the second guide plate 218 are installed in the second unit. According to the transmission direction of the strip, the second unit is respectively connected to the entrance pinch roller 211, the first guide plate 216, the trimming actuator 217, the second guide plate 218 and the exit pinch roller 215. When switching from the straightening mode to the trimming mode, the straightening and trimming system removes the first guide plate 216 and the second guide plate 218 installed between the inlet pinch roller 211 and the outlet pinch roller 215. The first guide plate 216 and the second guide plate 218 are removed from the second unit, and the inlet tension roller 212, the straightening actuator 213 and the outlet tension roller 214 are installed in the first unit. According to the transmission direction of the strip, the first unit is connected to the inlet pinch roller 211, the inlet tension roller 212, the straightening actuator 213, the outlet tension roller 214 and the outlet pinch roller 215 respectively.

[0056] In this embodiment, the tensioning and straightening trimming system further includes a disassembly and assembly auxiliary device for disassembling and assembling the first guide plate 216 and the second guide plate 218. In the trimming mode, the disassembly and assembly auxiliary device installs the first guide plate 216 and the second guide plate 218 to a preset position; in the tensioning and straightening mode, the disassembly and assembly auxiliary device removes the first guide plate 216 and the second guide plate 218 from the preset position.

[0057] By using the technical solution of this embodiment, the unit switching of the straightening and trimming system can be realized by disassembling the first guide plate and the second guide plate. The first unit and the second unit can respectively support the straightening and trimming system to perform straightening or trimming on the strip.

[0058] In some embodiments, in a direction perpendicular to the transmission direction of the strip steel, an entry tension roller is disposed under the first guide plate, and an exit tension roller is disposed under the second guide plate.

[0059] The technical solution of this embodiment describes the positional relationship between the inlet tension roller and the outlet tension roller, and the first guide plate and the second guide plate. Figure 5As shown, the first guide plate 216 is arranged above the inlet tension roller 212, and the second guide plate 218 is arranged above the outlet tension roller 214. The first guide plate is arranged at a first preset distance above the inlet tension roller, and the second guide plate is arranged at a second preset distance above the outlet tension roller, and the first preset distance and the second preset distance can be equal. In actual installation, the first guide plate 216 and the second guide plate 218 are convenient to be disassembled, and the first guide plate 216 and the second guide plate 218 can be quickly installed above the inlet tension roller 212 and the outlet tension roller 214, and the installed first guide plate 216 and the second guide plate 218 can also be quickly removed. During the transmission process of the inlet feed roller 211 and the outlet pinch roller 215, the strip steel can be transmitted through the first guide plate 216 and the second guide plate 218, or through the inlet tension roller 212 and the outlet tension roller 214, under the premise that the inlet pinch roller 211 and the outlet pinch roller 215 do not move. When the strip is transmitted through the first guide plate 216 and the second guide plate 218, the trimming actuator 217 between the first guide plate 216 and the second guide plate 218 performs the trimming action on the strip. When the strip is transmitted through the entrance tension roller 212 and the exit tension roller 214, the straightening actuator 213 between the entrance tension roller 212 and the exit tension roller 214 performs the straightening action on the strip.

[0060] In the straightening mode or trimming mode of the straightening and trimming system, the strip can be transferred from the entrance pinch roller to the first guide plate or the entrance tension roller, or from the second guide plate or the exit tension roller to the exit pinch roller, without adjusting the position or height of the entrance pinch roller and the exit pinch roller.

[0061] For example, Figure 6 As shown, when the straightening actuator 217 includes a scale-breaking straightening machine 217, in the straightening mode, the scale-breaking straightening machine 217 is located between the entrance tension roller 212 and the exit tension roller 214, the scale-breaking straightening machine 217 includes an upper straightening machine roller 2171 and a lower straightening machine roller 2172, the upper straightening machine roller 2171 and the lower straightening machine roller 2172 are clamped, and the upper straightening machine roller 2171 and the lower straightening machine roller 2172 jointly stretch and straighten the strip under the tension of the entrance tension roller 212 and the exit tension roller 214. When the straightening and trimming system switches from the straightening mode to the trimming mode, a first guide plate 216 is arranged above the entrance tension roller 212, and a second guide plate 218 is arranged above the exit tension roller 214. The strip is transmitted between the entrance pinch roller 211 and the exit pinch roller 215 through the first guide plate 216 and the second guide plate 218. The descaling straightening machine 217 is located between the first guide plate 216 and the second guide plate 218. The upper roller 2171 of the descaling straightening machine 217 is lifted, and the lower roller 2172 of the straightening machine is lowered, so that the strip can be transmitted between the upper roller 2171 and the lower roller 2172 of the straightening machine.

[0062] The present application provides a control method for a straightening and trimming system, which is applied to the straightening and trimming system, and specifically, can be applied to a controller of the straightening and trimming system, such as Figure 7 As shown, including:

[0063] Step 701, determining a target working mode of the stretching, straightening and trimming system, wherein the working modes of the stretching, straightening and trimming system include a stretching, straightening mode and a trimming mode.

[0064] The straightening and trimming system supports the straightening mode and the trimming mode. By working in the corresponding mode, the straightening and trimming system can perform the corresponding function of the mode. In the process of selecting the mode, the straightening and trimming system can set up a control button. The user can adjust the control button to select the target working mode of the straightening and trimming system as the straightening mode or the trimming mode. The straightening and trimming system determines the target working mode that the system needs to run.

[0065] Step 702, determining a target unit corresponding to the target working mode, where the target unit is the first unit or the second unit.

[0066] After the user selects the target working mode, the stretching, straightening and trimming system determines the target unit corresponding to the target working mode. When it is the stretching, straightening and trimming mode, the stretching, straightening and trimming system is the first unit, and when it is the trimming mode, the stretching, straightening and trimming system is the second unit.

[0067] Step 703, in the tension-straightening mode, control the first unit to tension-straighten the strip steel, or, in the trimming mode, control the second unit to trim the strip steel.

[0068] After determining the target working mode and target unit of the stretching, straightening and trimming system, the stretching, straightening and trimming system is enabled to perform the stretching, straightening and trimming function.

[0069] In the present embodiment, the straightening and trimming system includes multiple units, and the corresponding target unit can be selected according to the target working mode, and the unit corresponds to the mode one by one. In the present embodiment, the corresponding unit can be selected according to the function that the straightening and trimming system needs to perform.

[0070] In some embodiments, in the trimming mode, the inlet tension roller, the straightening actuator and the outlet tension roller are controlled to stop running.

[0071] In this embodiment, when the straightening and trimming system is in the straightening mode, the entrance pinch roller, the entrance tension roller, the straightening actuator, the exit tension roller, and the entrance pinch roller perform the straightening function. However, when switching to the trimming mode, the entrance tension roller, the straightening actuator, and the exit tension roller started in the straightening mode stop running. In the trimming mode, since the strip steel is repeatedly bent at the entrance tension roller and the exit tension roller, the strip steel is prone to breakage when the trimming operation is performed. Therefore, in the trimming mode, the entrance tension roller, the straightening actuator, and the exit tension roller are stopped at the same time to reduce the probability that the strip steel is prone to breakage during trimming due to repeated bending when running in the straightening and trimming system.

[0072] In some embodiments, when the first guide plate and the second guide plate are detachable guide plates, before controlling the second unit to trim the strip, the method further includes:

[0073] The first guide plate is controlled to be installed between the inlet pinch roller and the trimming actuator, and the second guide plate is controlled to be installed between the outlet pinch roller and the trimming actuator.

[0074] Before the stretching and straightening trimming system performs the trimming function, the controller executes the installation of the first guide plate and the second guide plate. The installation of the first guide plate and the second guide plate can be performed by the disassembly and assembly auxiliary equipment, and the disassembly and assembly auxiliary equipment can install the first guide plate and the second guide plate above the inlet tension roller and the outlet tension roller, respectively. The controller can control the activation and shutdown of the disassembly and assembly auxiliary equipment. When the controller activates the disassembly and assembly auxiliary equipment to install the first guide plate and the second guide plate, the disassembly and assembly equipment can install the first guide plate and the second guide plate above the inlet tension roller and the outlet tension roller, respectively. When the controller activates the disassembly and assembly auxiliary equipment to remove the first guide plate and the second guide plate, the disassembly and assembly equipment can remove the first guide plate and the second guide plate from above the inlet tension roller and the outlet tension roller, thereby realizing the automatic control of the stretching and straightening trimming system.
