Description

Technical Field

[0001] The present invention relates to a multi-functional cross-cutting line material distribution table, belonging to the technical field of transformer core production. Background Art

[0002] With the construction of large-scale hydropower stations and wind power stations, the demand for transformer cores suitable for high-voltage and extra-high-voltage is increasing day by day, and the production of large-sized transformer cores is becoming increasingly important. In the production of transformer cores, cross-cutting is an important process. After shearing is completed by a punching machine or a shearing machine, generally discharging and material distribution are carried out.

[0003] However, in this process of the existing technology, many cross-cutting line devices do not pay attention to the influence of size increase on discharging and material distribution, so problems such as silicon steel sheet corner collision and misdetection of material distribution will occur, which has a great impact on the product quality of silicon steel sheets.

[0004] Specifically, for large-width silicon steel sheets, the V-notch of the V-punch increases. An over-large V-notch of the V-punch will lead to misdetection of material distribution. The failure of the material distribution detection sensor will result in poor product consistency, and there is also a problem that the sensor fails without alarm, so the failure cannot be eliminated in time, affecting production efficiency. Summary of the Invention

[0005] The present invention provides a multi-functional cross-cutting line material distribution table, aiming to overcome the above deficiencies existing in the prior art, avoid corner collision of silicon steel sheets, improve the smoothness of discharging, avoid misdetection of material distribution, and reduce the probability of downtime.

[0006] The technical solution of the present invention: A multi-functional cross-cutting line material distribution table, the structure of which includes a pre-material distribution track that always maintains a fixed distance from the second shear. The pre-material distribution track is used to restrain the formed silicon steel sheets discharged through the discharging roller, avoiding deformation and fluctuation of the silicon steel sheets. At one end of the pre-material distribution track, there are 3 proximity sensors fixed on a sensor fixing seat. On the outer side of the proximity sensors away from the pre-material distribution track, there are a material distribution upper track and a material distribution lower track arranged at intervals up and down, which are used to transport the finished silicon steel sheets to the stack. On the outer side of the pre-material distribution track away from the sensor fixing seat, there is a shearing machine movable platform perpendicular to the sliding direction of the pre-material distribution track in the horizontal direction, which is used to ensure that the silicon steel sheets after shearing pass through the pre-material distribution track; on the shearing machine movable platform, there are a second shear and a first shear, and the second shear is close to the pre-material distribution track.

[0007] Preferably, the shearing machine movable platform is slidably connected to a shearing machine movable platform slider rail perpendicular to the pre-material distribution track in the horizontal direction.

[0008] Preferably, the three proximity sensors include an A proximity sensor, a B proximity sensor, and a C proximity sensor spaced in sequence from the place close to the pre-material distribution track to the place far from the pre-material distribution track. The material distribution upper track and the material distribution lower track are arranged on the outer side of the C proximity sensor away from the pre-material distribution track.

[0009] Preferably, the sensor fixing base is connected to the main frame of the blanking table. The main frame of the blanking table is arranged above the pre-blanking track, and the main frame of the blanking table is installed on the machine frame through legs.

[0010] Preferably, the pre-blanking track is installed on the telescopic track of the blanking table; the telescopic track of the blanking table is slidably connected to the telescopic slider rail on the bottom surface of the main frame of the blanking table. The telescopic track of the blanking table expands and contracts with the movement of the movable platform of the shearing machine, and always keeps the distance between the pre-blanking track and the second shearing blade fixed.

[0011] Preferably, the A proximity sensor, the B proximity sensor, and the C proximity sensor are all PNP type proximity sensors with an effective range of 5 mm.

[0012] Preferably, the A proximity sensor, the B proximity sensor, and the C proximity sensor are fixed at equal distances, and the distance is 1 / 4 of the maximum width Bmax that can be produced by the production line, and the distance from the silicon steel sheet on the pre-blanking track is 3 mm.

[0013] The distance between the A proximity sensor and the B proximity sensor is equal to the distance between the B proximity sensor and the C proximity sensor and is 1 / 2 of the distance between the A proximity sensor and the C proximity sensor, 2L1 = 2L2 = L3.

[0014] A sensor alarm method for the blanking table of a multi-functional horizontal shearing line includes: recording the time difference between the action times of the A proximity sensor and the B proximity sensor as T1, recording the time difference between the action times of the B proximity sensor and the C proximity sensor as T2, recording the time difference between the action times of the A proximity sensor and the C proximity sensor as T3. After adjustment, record the time difference between the action times of the A proximity sensor and the B proximity sensor multiple times as T0. Keep the discharging speed unchanged, 2T0 = 2T1 = 2T2 = T3. When detecting, detect the action time of the proximity sensor. When the time difference does not meet the set value, give an alarm, otherwise it can be used normally.

[0015] Preferably, when detecting the action time of the proximity sensor and giving an alarm when the time difference does not meet the set value, otherwise using it normally, specifically includes: 1) If the difference between T0 and T1 is ≤ 0.05 s, then proceed to step 2), otherwise give an alarm;

[0016] 2) If the difference between T0 and T2 is ≤ 0.05 s, then proceed to step 3), otherwise give an alarm;

[0017] 3) If the difference between 2T0 and T3 is ≤ 0.05 s, then use it normally, otherwise give an alarm.

[0018] Advantages of the present invention: The gap between the second cutting blade support plate and the track before material separation during the material discharging process is fixed, avoiding problems such as the silicon steel sheet sagging and hitting the corner under the action of gravity and poor material discharging when the gap is too large; at the same time, the spacing is fixed by using three proximity sensors, and the position change of the sensors can be alarmed by themselves using permutations and combinations, and the misdetection of material separation of large-width silicon steel sheets is avoided. Moreover, when a certain sensor fails, the remaining sensors can be used temporarily, reducing the impact of shutdown in case of emergencies and ensuring production efficiency.

Specific Embodiments

[0026] The present invention will be further described in detail below in conjunction with the embodiments and specific implementation manners.

[0027] Such as Figures 1-3As shown in the figure, a multi-functional material distribution table for a horizontal shearing line, the structure of which includes a front material distribution track 2 installed on the telescopic track 10 of the material distribution table. The front material distribution track 2 is used to restrain the formed silicon steel sheets discharged by the discharging rollers, avoiding deformation and fluctuation of the silicon steel sheets. The telescopic track 10 of the material distribution table is slidably connected to the telescopic slider rail 11 of the material distribution table on the bottom surface of the main frame 12 of the material distribution table. The telescopic track 10 of the material distribution table expands and contracts with the movement of the movable platform 1 of the shearing machine, always keeping the distance between the front material distribution track 2 and the second shearing knife 14 fixed. One end of the front material distribution track 2 is provided with a sensor fixing seat 3. On the sensor fixing seat 3, an A proximity sensor 4, a B proximity sensor 5 and a C proximity sensor 6 are sequentially arranged at intervals from the place close to the front material distribution track 2 to the place far from the front material distribution track 2. The sensor fixing seat 3 is directly connected to the main frame 12 of the material distribution table by a high-strength alloy. The main frame 12 of the material distribution table is arranged above the front material distribution track 2, and the main frame 12 of the material distribution table is installed on the machine frame through legs. Outside the C proximity sensor 6 far from the front material distribution track 2, a upper material distribution track 7 and a lower material distribution track 8 are arranged at intervals up and down, which are used to transport the finished silicon steel sheets to the stacking area. Outside the front material distribution track 2 far from the sensor fixing seat 3, there is a movable platform 1 of the shearing machine. The movable platform 1 of the shearing machine is slidably connected to the slider rail 9 of the movable platform of the shearing machine which is perpendicular to the front material distribution track 2 in the horizontal direction, and the side is connected by a screw drive, which is used to ensure that the silicon steel sheets after shearing pass through the front material distribution track 2. On the movable platform 1 of the shearing machine, there are a first shearing knife 13 and a second shearing knife 14, and the second shearing knife 14 is close to the main frame 12 of the material distribution table.

[0028] The sensor fixing seat 3 and the main frame 12 of the material distribution table should ensure close contact and no obvious deformation during vibration. The A proximity sensor 4, the B proximity sensor 5 and the C proximity sensor 6 are all PNP type proximity sensors, with an effective range of 5 mm, and are fixed at equal distances through the sensor fixing seat 3, and the distance is 1 / 4 of the maximum width Bmax that the production line can produce, and at the same time, the distance from the silicon steel sheet on the front material distribution track 2 is 3 mm.

[0029] The first shearing knife 13 and the second shearing knife 14 move back and forth on the slider rail 9 of the movable platform of the shearing machine along with the movable platform 1 of the shearing machine. At this time, the front material distribution track 2 moves correspondingly to ensure that the silicon steel sheets enter the front material distribution track 2. At the same time, the telescopic track 10 of the material distribution table expands and contracts correspondingly to ensure that the distance from the second shearing knife 14 is fixed, and provides power for the formed silicon steel sheets to speed up the discharging.

[0030] As Figure 4As shown in the figure, the distance between proximity sensor 4 of A and proximity sensor 5 of B is L1, the distance between proximity sensor 5 of B and proximity sensor 6 of C is L2, and the distance between proximity sensor 4 of A and proximity sensor 6 of C is L3. 2L1 = 2L2 = L3. The difference in the action time between proximity sensor 4 of A and proximity sensor 5 of B is denoted as T1, the difference in the action time between proximity sensor 5 of B and proximity sensor 6 of C is denoted as T2, and the difference in the action time between proximity sensor 4 of A and proximity sensor 6 of C is denoted as T3. After adjustment, record the difference in the action time between proximity sensor 4 of A and proximity sensor 5 of B multiple times and denote it as T0. Since the discharging speed remains unchanged, 2T0 = 2T1 = 2T2 = T3, as Figure 5 As shown in the figure, when detecting, the action time of the proximity sensor is detected, and an alarm is given when there is a problem with the time difference. Embodiment

[0031] The sheet type with the highest possibility of false detection is as Figure 6 As shown in the figure, the trigger signals of proximity sensor 4 of A, proximity sensor 5 of B, and proximity sensor 6 of C are denoted as I6.0, I6.1, and I6.2. When the detection position of the sensor group is on the L line, the signals of I6.0, I6.1, and I6.2 all change from 0 to 1 and then from 1 to 0. When I6.0, I6.1, and I6.2 are all 0, it is recorded as the end of one sheet; when the detection position of the sensor group is above the L line and T1 is greater than L1, if only two proximity sensors exist, at this time the signal has exceeded one sheet and false detection occurs; however, at this time because L3 > Bmax, the signals of the sensor group I6.0, I6.1, and I6.2 are not all 0, so false detection will not occur, and an out-of-position alarm can be generated to remind to adjust the front track 2 of the material distributor.

[0032] All the above components are prior arts, and those skilled in the art can use any models and existing designs that can achieve their corresponding functions.

[0033] The above is only the preferred embodiment of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the inventive concept of the present invention, several modifications and improvements can still be made, and these all belong to the protection scope of the present invention.
