The invention discloses a steel plate coiling device. The steel plate coiling device comprises an oil cylinder, a telescopic shaft, a main shaft and blades; the blades are in a sector shape; the four sector-shaped blades are combined to form a cylindrical structure; the main shaft is placed in the center of the cylindrical structure and extends out of the cylindrical structure; the telescopic shaft is connected with the main shaft and is connected with the oil cylinder; a plurality of conical grooves are formed in the main shaft; a taper strip is arranged at the position, corresponding to the conical groove, of each blade; the taper strips can be embedded in the conical grooves and can move along the obliquity of the conical grooves. According to the mode, the blades and the main shaft of a coiling block can flexibly expand and retract; taper blocks fixed to the blades flexibly slide in the conical grooves in the main shaft; the dead clamping condition is not prone to happening, and coiling of a steel plate is facilitated.

The invention discloses an aluminum plate coiling device for automobile part production. The structure of the aluminum plate coiling device comprises a supporting frame, a double-face heating mechanism, a hook arm, an angle adjusting frame, an aluminum plate, a coiling rotating sleeve, a center roller, a fixing hook, a rotating power roller, a power crate, a coiling machine body, a machine base and a motor. The double-face heating mechanism is transversely arranged between the supporting frame and the power crate and connected with the supporting frame and the power crate in an electric welding mode. The hook arm is arranged on the front portion of the upper end of the supporting frame and connected with the upper end of the supporting frame through a hinge. The aluminum plate coiling device for automobile part production has the beneficial effects that the double-face heating mechanism is arranged, and the distance between an upper heating roller and a lower heating roller can be automatically adjusted according to the thickness of the aluminum plate, so that the heating rollers make effective contact with the aluminum plate, rapid heating of the aluminum plate is achieved, the aluminum plate is made to soft and easy to coil, the coiling rate is increased, coiling gaps are reduced, the coiling efficiency of the aluminum plate coiling device for automobile part production is effectively improved, and the coiling precision is improved.

The invention discloses a process optimization method for improving the taking and threading of ultra-thin strip steel, which belongs to the technical field of steel rolling. The process optimization method for improving ultra-thin strip steel taking and threading includes modifying the exit shape of the strip steel in the pickling rolling process to ensure that the shape of the strip steel exit is medium wave IU; the position of the pinch roll at the exit of the rolling mill Adjust and compensate for offset; adjust the working pressure of the pinch roll and increase the working pressure of the pinch roll; optimize the air purge pressure at the outlet of the rolling mill to reduce the friction pressure between the strip steel and the guide plate during the strip threading process; modify the physics of the strip threading guide plate at the exit of the rolling mill structure to reduce friction in the strip threading process; optimize the lead rate and speed of the exit equipment of the rolling mill to ensure coiling. The invention improves the process optimization method for taking and threading of ultra-thin strips, effectively reduces the probability and accidents of coiling and threading of ultra-thin strips at the exit of acid rolling, and effectively improves the volume of ultra-thin strips, especially at the exit of acid rolling. Take strap stability.
