The purpose of arranging the protruding parts 2-5 to be matched with the grooves 1-1 is mainly to arrange staggered layers at the gaps between the four annular section pressing plates and the central pressing plate 1.
In order to further ensure the stability of the central pressing plate 1 and the auxiliary pressing plate 2, a guide rail 6 is vertically arranged on the bracket 3, guide rail grooves matched with the guide rail 6 are formed in the central pressing plate 1 and the auxiliary pressing plate 2, and the central pressing plate 1 and the auxiliary pressing plate 2 can slide up and down along the guide rail 6. As shown in fig. 2, the guide rails 6 may be configured as 6T-shaped guide rails, each of which is used in cooperation with two adjacent auxiliary pressing plates and a central pressing plate.
In order to automatically identify whether the starting center pressing plate 1 or the auxiliary pressing plate 2 is flattened, a CPU, an infrared monitoring mechanism and a control circuit are arranged; the infrared monitoring mechanism is horizontally arranged and comprises an infrared emission component 7 and an infrared receiving component 8, wherein the height of infrared light is 2-10mm higher than the upper end face of a steel coil 9, the infrared emission component 7 consists of a first infrared emission tube 7-1 and a second infrared emission tube 7-2, and the infrared receiving component 8 consists of a first infrared receiving tube 8-1 and a second infrared receiving tube 8-2; the first infrared transmitting tube 7-1 is matched with the first infrared receiving tube 8-1, the first infrared light emitted by the first infrared transmitting tube passes through the axis of the steel coil 9, the second infrared transmitting tube 7-2 is matched with the second infrared receiving tube 8-2, the second infrared light emitted by the second infrared transmitting tube is parallel to the first infrared light, and the distance between the first infrared light and the second infrared light is equal to the radius of the central pressing plate 1; the signal output ends of the first infrared receiving tube 8-1, the second infrared receiving tube 8-2 and the pressure sensor are connected with the input end of the CPU, and the signal output ends of the CPU are respectively connected with the hydraulic pump through relays to control the start and stop of the hydraulic pump. The input/output connection control of the above CPU may specifically be: the first infrared receiving tube 8-1 and the second infrared receiving tube 8-2 are respectively connected with the P1.0-P1.1 input end of the CPU, and each pressure sensor is respectively connected with the P1.2-P1.6 input end of the CPU; the output end of the CPU can be connected with a control coil of the relay through a triode, and a normally closed contact of the relay is connected with the hydraulic pump.

Since the first infrared light passes through the axis of the steel coil 9, when the detection of the first infrared light is blocked, the steel coil 9 is necessarily staggered. When the second infrared light is blocked, the outer diameter of the staggered layer is necessarily larger than or equal to the outer diameter of the central pressing plate 1, and after the signal is transmitted to the CPU, the CPU starts the auxiliary pressing plate 2 to flatten through analysis and calculation. When the second infrared light is not blocked, the outer diameter of the staggered layer is necessarily smaller than the outer diameter of the central pressing plate 1, and after the signal is transmitted to the CPU, the CPU starts the central pressing plate 1 to flatten through analysis and calculation. There are, of course, extreme cases where the staggered layers extend from the centre all the way to the very outer ring of the coil 9, where the CPU would control the auxiliary presser 2 to flatten first and then the centre presser 1.
In the flattening process of the auxiliary pressing plate 2, if the first auxiliary pressing plate 2-1, the second auxiliary pressing plate 2-2, the third auxiliary pressing plate 2-3 and the fourth auxiliary pressing plate 2-4 can be synchronized as much as possible, the flattening effect on steel coils is good, at this time, a pressure sensor arranged in a control liquid path of each hydraulic cylinder plays a role, when the flattening process of one auxiliary pressing plate 2 is faster, the resistance encountered by the other positions of the steel coils 9 is inevitably increased due to the influence of slower resistance of staggered-layer flattening in the pressing process, the oil pressure in an oil path is increased, after the pressure sensor transmits signals to a CPU (central processing unit), the CPU controls the corresponding hydraulic pump to stop working, and after the flattening progress of the other positions catches up with the progress, the hydraulic pump started to stop working is started to work, so that the staggered-layer synchronous flattening is finally realized.
