Referring to fig. 1 to 3, in a preferred embodiment of the present invention, a leveling machine for dynamically adjusting a leveling gap includes an upper roller set 1, a lower roller set 2, a base 3, and a top frame 4, wherein the upper roller set 1 and the lower roller set 2 are respectively connected to a power reduction unit 5, the upper roller set 1 includes an upper roller base 11, an upper leveling roller 12, and an upper carrier roller 13, the upper roller base 11 is movably mounted on the top frame 4, the upper leveling roller 12 and the upper carrier roller 13 are rotatably connected to the upper roller base 11, the lower roller set 2 includes a lower roller base 21, a lower leveling roller 22, and a lower carrier roller 23, the lower roller base 21 is fixed to the base 3, the lower leveling roller 22 and the lower carrier roller 23 are rotatably connected to the lower roller base 21, the upper carrier roller 13 is positioned above the upper leveling roller 12, the lower carrier roller 23 is positioned below the lower leveling roller 22, and the upper leveling roller 12 and the upper carrier roller 13 are alternately arranged, the lower leveling rollers 22 and the lower supporting rollers 23 are arranged in a staggered manner, the upper leveling rollers 12 and the lower leveling rollers 22 are arranged in a staggered manner, four corners of the top frame 4 are respectively provided with an independently controlled hydraulic cylinder 6, the lower ends of piston rods of the four hydraulic cylinders 6 are respectively rotatably connected with four corners of the upper roller seat 11, four corners of the upper roller seat 11 or the lower roller seat 21 are respectively provided with a displacement sensor 7 for detecting offset generated by the upper roller seat 11 relative to the lower roller seat 21 in the leveling process, and the displacement sensor 7 and an electro-hydraulic servo valve of the hydraulic cylinder 6 are respectively and electrically connected with the electric cabinet 8. From this, in the flattening process, displacement sensor 7 can feed back the offset (the change in flattening clearance) that leads to upper roll seat 11 to produce relatively lower roll seat 21 when the thickness of work piece local position differs to electric cabinet 8 in real time, and electric cabinet 8 can carry out dynamic adjustment to the flattening clearance in real time according to the action of 4 pneumatic cylinders 6 respectively of the signal of displacement sensor 7 real-time feedback simultaneously, solves the problem that the work piece self thickness leads to the change in flattening clearance when not differing effectively, the atress is uneven, ensures excellent flattening effect.
Illustratively, the hydraulic cylinder 6 is externally connected with a hydraulic station 9 through an electro-hydraulic servo valve; and the electric control box 8 is electrically connected with a touch screen 10. Therefore, before the leveling work is started, technical parameters (such as materials and thickness) of a workpiece can be input through the touch screen 10, the electric control box 8 can call corresponding leveling gaps through the experience database, and then the hydraulic cylinder 6 is controlled to enable the upper roller group 1 and the lower roller group 2 to be automatically adjusted to the optimal positions; in the leveling process, the electric cabinet 8 can obtain a digital visible process value according to a signal fed back by the displacement sensor 7 in real time, and on one hand, the digital visible process value is transmitted to the touch screen 10 for monitoring; on the other hand, the value is sent to an electro-hydraulic servo valve to control the flow rate of oil, so that the value is converted into accurate operation of the hydraulic cylinder 6.
For example, most of the gear sets adopted by the existing leveling power reduction device are sequentially connected by driving the leveling roller end gears 102 through a plurality of carrier gears 101 (as shown in fig. 4), when power is transmitted to one of the carrier gears, the other gears can be driven one by one, but in practical application, due to the existence of errors, the action of the gear is more delayed on the side farther away from the power, so that the synchronism of the leveling rollers is directly influenced, the phenomena of scratches on the surface of a workpiece and the abrasion of the leveling rollers are caused, and the gear pair with the structure is more, and under the condition that the number of the leveling rollers is the same, the energy loss between the gear transmissions is large. In the present embodiment, as shown in fig. 5 and 6, the power reduction device 5 includes a driver 51, a transmission shaft 52, a first bevel gear 53, a second bevel gear 54, a first cylindrical gear 55 and a second cylindrical gear 56, a power output end of the driver 51 is connected to the transmission shaft 52, the first bevel gear 53, the second bevel gear 54 and the first cylindrical gear 55 are provided in plural and in the same number, the number of the second bevel gear 56 is twice the number of the first cylindrical gear 55, the plural first bevel gears 53 are connected to the transmission shaft 52 at intervals, the second bevel gears 54 are in one-to-one engagement with the first bevel gears 53, an axis of the second bevel gear 54 intersects with an axis of the first bevel gear 53 at 90 degrees, the first cylindrical gear 55 is connected to the second bevel gear 54 coaxially, each of the first cylindrical gears 55 is engaged with one or two of the second cylindrical gears 56, and each of the second cylindrical gears 56 is connected to an output shaft 57 connected to the leveling roller. Therefore, a plurality of transmission gear groups arranged at intervals are connected in a penetrating manner through the transmission shaft 52, and one transmission gear group is designed to be responsible for power output of two adjacent leveling rollers in a leveling zero manner, so that the actions of the rollers are consistent, and the phenomena of workpiece surface scratch and leveling roller abrasion caused by the speed difference among the rollers are effectively avoided.
As shown in fig. 5, taking 10 leveling rollers as an example, 5 first bevel gears 53, 5 second bevel gears 54 and 5 first cylindrical gears 55 are provided, 10 second bevel gears 56 are provided, and 15 gear pairs are formed by the gear set. In the configuration shown in fig. 4, there are at least 18 gear pairs without counting drive gears, reduction gears, and the like.

Illustratively, when the number of the upper leveling rolls 12 or the lower leveling rolls 22 is an odd number N, the first bevel gear 53, the second bevel gear 54, and the first cylindrical gear 55 are each provided with (N + 1)/2; n second cylindrical gears 56 are provided, wherein the first cylindrical gear 55 on the side away from the driver 51 is meshed with one second cylindrical gear 56, and each of the remaining first cylindrical gears 55 is meshed with two second cylindrical gears 56; when the number of the upper leveling rolls 12 or the lower leveling rolls 22 is an even number M, the first bevel gear 53, the second bevel gear 54, and the first cylindrical gear 55 are each provided in M/2, and the second cylindrical gear 56 is provided in M, wherein each of the first cylindrical gears 55 is engaged with two of the second cylindrical gears 56.
