Description
Technical Field
The utility model relates to the technical field of machining, in particular to a rigid direct-connection servo driving structure of a plate straightener.
Background
The straightening machine is equipment for straightening metal sections, bars, pipes, wires and the like. The straightener extrudes the bar and the like through the straightening rollers to change the straightness of the bar. Generally, two rows of straightening rollers are provided, and the number of straightening rollers is different. There are also two-roll straightening machines, which straighten materials of different diameters by the change of the angle of two rolls. The main types are a pressure straightener, a balance roll straightener, a shoe roll straightener, a rotary reverse bend straightener and the like. The rollers are positioned at an angle to the direction of movement of the article being straightened, two or three of the larger rollers being driven pressure rollers which are driven by motor belts to rotate in the same direction, and the other of the smaller rollers being driven pressure rollers which are caused to rotate by friction against the rotating round bar or tube. The small rollers can be adjusted in position simultaneously or separately in a forward or backward direction in order to achieve the desired compression of the product by the rollers, and generally the greater the number of rollers, the greater the precision of the straightened product. After the product is bitten by the roller, the product is continuously moved linearly or rotationally, so that the product is subjected to deformation such as compression, bending, flattening and the like in all aspects, and finally the aim of straightening is fulfilled.
In the original driving structure of the plate straightener, the upper straightening roller and the lower straightening roller are connected with the distribution box through universal couplings, and the straightening rollers are driven to rotate through the universal couplings. The connection driving mode ensures that the straightening roller and the output shaft on the distribution box are not on the same axis, so that when the roller gap of the box body on the straightening machine is adjusted, one end of the box body can drive the universal coupling to move up and down. With such a connection, the outermost universal joint may have a large operational offset angle and axial offset. Meanwhile, the universal coupling needs to have good lubrication, and the universal coupling can break once the lubrication fails. Meanwhile, due to the fact that stress of the plate is uneven, the universal coupling receives uneven torque impact when the straightening machine works, and the universal coupling is prone to breaking. On the other hand, the driving force is limited, so that the leveling requirements of special plates such as high-strength steel plates and the like cannot be met, and the high-strength steel plates and the like are the development trend of the current steel industry.
