In the embodiment, the pressure detection element is arranged at the outlet of the locking cylinder, so that the pressure data in the oil pipe of the locking cylinder is detected in real time; the laser range finder is arranged on the moving side of the double-sided shear rack, and the transverse displacement of the moving side of the double-sided shear rack is detected in real time; arranging an encoder at the crankshaft, and detecting the motion state and the motion position of the crankshaft in real time; finally, the controller is connected with a pressure detection element, a laser range finder and an encoder to obtain the detected pressure data in the oil pipe of the locking cylinder, the detected lateral displacement of the moving side of the bilateral scissors frame, and the detected motion state and motion position of the crankshaft in real time; and the controller judges the data acquired in real time to determine whether the double-side shearing machine frame has a displacement fault.

In an exemplary embodiment, the device comprises two pressure detecting elements, a first pressure detecting element 5 and a second pressure detecting element 6, respectively. A first pressure detection element 5 is arranged at an outlet of a locking cylinder control valve at a moving side inlet of a double-sided shear rack; and the second pressure detection element 6 is arranged at the outlet of a locking cylinder control valve at the moving side outlet of the double-sided shear frame. The first pressure detection element 5 is used for detecting pressure data in an oil pipe at an outlet of a locking cylinder control valve at a moving side inlet of the double-sided shears rack; the second pressure detection element 6 is used for detecting pressure data in an oil pipe at the outlet of the locking cylinder control valve at the moving side outlet of the double-sided shears rack. And the first pressure detecting element 5 and the second pressure detecting element 6 input the detected pressure data to the controller 1 by analog quantity signals; the analog quantity signal transmitted by the first pressure detection element 5 is SP1, and the analog quantity signal transmitted by the second pressure detection element 6 is SP 2. And the double-sided shear frame comprises a laser range finder 7, wherein the laser range finder 7 is arranged at the moving side of the double-sided shear frame, the position change value of the moving side of the double-sided shear frame is detected in real time (namely the transverse displacement of the moving side of the double-sided shear frame is detected in real time) through the laser range finder 7, and the laser range finder 7 transmits the detected position change value (or the transverse displacement) to the controller 1 in real time. The detection precision of the laser range finder 7 in the embodiment of the present application is 1 mm. The double-sided shear comprises an encoder 4, wherein the encoder 4 is installed at a crankshaft of the double-sided shear and used for detecting the motion state and the motion position of the crankshaft in real time, and the motion state and the motion position of a main shearing knife in the double-sided shear can be determined by detecting the motion state and the motion position of the crankshaft in real time. Wherein, the current data value detected by the encoder 4 represents the current position of the main shearing knife in the double-sided shear; the continuous data change state of the encoder 4 represents the motion state of the main shearing blade in the double-sided shears. And the controller 1 is connected with the first pressure detection element 5, the second pressure detection element 6, the laser range finder 7 and the encoder 4 through the I/O interface module respectively. The controller 1 is used for acquiring pressure data detected by the first pressure detection element 5, pressure data detected by the second pressure detection element 6, the lateral displacement of the moving side of the double-sided scissors frame detected by the laser range finder 7, a numerical value detected by the encoder 4 and a numerical value continuous change state in real time.
In an exemplary embodiment, when the controller 1 determines the pressure data in the oil pipe of the locking cylinder, the lateral displacement of the double-sided shears frame on the moving side, and the motion state and the motion position of the crankshaft, which are acquired in real time, the following processing is further performed:
the pressure data detected by the pressure detection element is converted into a decimal pressure numerical value, and/or the lateral movement amount of the moving side of the double-sided shear frame detected by the laser range finder 7 is converted into a decimal opening degree value of the double-sided shear frame, and/or the motion state and the motion position of the crankshaft detected by the encoder 4 are converted into an angle value of 0-360 degrees.
In an exemplary embodiment, if the controller 1 determines that the acquired pressure data in the oil pipe of the locking cylinder is smaller than a preset pressure value at a certain moment; judging that the obtained lateral movement amount of the moving side of the double-sided shear rack is larger than a preset distance value; judging that the obtained motion state of the crankshaft is inconsistent with the motion state of the crankshaft in normal shearing; judging that the obtained motion position of the crankshaft is not located in the motion position range of the crankshaft during normal shearing; it is determined that the double-sided shear frame has a displacement fault at that time.
According to the description of the above embodiment, specifically, as shown in fig. 1, the encoder 4, the first pressure detecting element 5, the second pressure detecting element 6, and the laser range finder 7 are respectively connected to the controller 1 through the I/O interface module. Before the bilateral scissors begin to shear the steel plate, the opening degree of the bilateral scissors frame is adjusted to a preset position by adjusting the lateral movement mechanism of the bilateral scissors frame, the moving side of the bilateral scissors frame is locked by the locking cylinder, and at the moment, the initial value L1 of the laser range finder 7 is locked. When the bilateral scissors start shearing, a first pressure detection element 5 detects pressure data in an oil pipe at an outlet of a locking cylinder control valve at a moving side inlet of a bilateral scissors rack in real time and transmits the pressure data to the controller 1 in real time through the I/O interface module 3; the second pressure detection element 6 detects pressure data in an oil pipe at the outlet of a locking cylinder control valve at the moving side outlet of the double-sided shear rack in real time and transmits the pressure data to the controller 1 in real time through the I/O interface module 3; the laser range finder 7 detects the opening degree value of the double-sided shear rack (or the lateral displacement of the moving side of the double-sided shear rack) in the shearing process in real time and transmits the opening degree value to the controller 1 in real time through the I/O interface module 3; the encoder 4 detects the angle data reflecting the motion state of the crankshaft of the double-sided shear in real time and transmits the angle data to the controller 1 in real time through the I/O interface module 3.
After the controller 1 acquires data through the I/O interface module 3, the acquired data is initially processed. The method comprises the steps of firstly converting pressure data transmitted by a first pressure detection element 5 and a second pressure detection element 6 into decimal pressure numerical values, and/or converting a bilateral scissors frame opening degree value (or a lateral displacement amount of a moving side of the bilateral scissors frame) transmitted by a laser range finder 7 into decimal bilateral scissors frame opening degree value Lx, and/or converting angle data which is transmitted by an encoder 4 and reflects the motion state of a crankshaft of the bilateral scissors into an angle value of 0-360 degrees.
After the controller 1 performs preliminary processing on the acquired data, it is determined whether or not a failure determination is required. The processed real-time rack opening value Lx is compared with the initial value L1 of the laser rangefinder 7. With L1 as the origin, the change direction and trend of Lx based on L1 are analyzed to obtain the displacement direction and the displacement of the double-sided scissors frame. When the displacement of the double-sided shears increases and exceeds the preset displacement value and the displacement process is irreversible (for example, the displacement variation cannot be recovered through elastic deformation), the controller 1 starts to judge whether the double-sided shears have the displacement fault. The preset displacement value in the embodiment of the application can be set according to actual conditions, but must be smaller than 15mm of national standard, and the preset displacement value of the application is set to be 2 mm.
When the displacement fault is judged, whether the first pressure detection element 5 and the second pressure detection element 6 have faults or not is judged firstly, so that the pressure data in the oil pipe of the locking cylinder, which are detected by the first pressure detection element 5 and the second pressure detection element 6, are credible. If the analog signal SP1 transmitted from the first pressure detection element 5 to the controller 1 via the I/O interface module 3 is a failure signal (or transmits a digital "27648" to the controller 1 via the I/O interface module 3), it is determined that the first pressure detection element 5 is failed. Similarly, if the analog signal SP2 transmitted from the second pressure detection element 6 to the controller 1 via the I/O interface module 3 is a fault signal (or transmits a digital signal "27648" to the controller 1 via the I/O interface module 3), it is determined that the second pressure detection element 6 is faulty. The first pressure detecting element 5 and/or the second pressure detecting element 6 are replaced first. If the analog quantity signals SP1 and SP2 transmitted by the first pressure detection element 5 and the second pressure detection element 6 to the controller 1 through the I/O interface module 3 are both normal signals, then whether the locking cylinder control valve leaks inwards is judged according to the detected pressure data in the locking cylinder oil pipe. And if the pressure data in the oil pipe of the locking cylinder is smaller than the preset pressure value, judging that the locking cylinder control valve has internal leakage.
Meanwhile, the starting point and the ending point of the main shearing knife for shearing the steel plate are judged through the numerical value of the encoder 4. And intercepting the displacement variation Lx1 of the lateral movement of the rack in the time period and intercepting the displacement variation Lx2 of the lateral movement of the rack before and after the withdrawal of the cutter withdrawing mechanism of the double-sided shears. When Lx1-L1 is larger than 2mm and SP1 and SP2 are normal signals, the pressing disc spring is judged to be loose or insufficient. When Lx2-L1 is larger than 4mm and SP1 and SP2 are normal signals, the cutter retracting mechanism is judged to be in fault.
According to the description, when the controller 1 judges that the displacement of the double-sided shear is more than 2mm at a certain moment; when the pressure detection element is normal, the locking cylinder control valve is internally leaked; and the bilateral scissors have faults when shearing (namely the pressure disc spring is loosened, the pressing force for pressing the disc spring is insufficient, or the cutter withdrawing mechanism has faults); determining that the double-side shearing machine frame at the moment has a displacement fault.

The invention can determine whether the bilateral shears frame has the transverse moving fault according to the determination result by monitoring the operation data when the bilateral shears shear shears the steel plate, namely detecting the change trend of the transverse moving numerical value of the frame, the change trend of the pressure of the locking cylinder of the frame and the motion state and the motion position of the crankshaft in real time, and then determining the operation data detected in real time.
