The invention discloses a watchband punching and cutting integrated system and a positioning device, and relates to the technical field of watchband machining.The integrated system comprises a frame, a bearing assembly is arranged on the bottom side of the interior of the frame, a feeding assembly is arranged at the end of the bearing assembly, a punching assembly is arranged at the top of the frame, and a cutting assembly is arranged on the side, away from the feeding assembly, of the punching assembly; the bearing assembly comprises a support, a convex table is arranged at the top of the support, material grooves are evenly formed in the top face of the convex table, guide holes are evenly formed in the inner bottom faces of the material grooves, the feeding assembly comprises a frame base, an auxiliary roller is rotationally connected to the frame base, a mounting base is arranged above the auxiliary roller, and a feeding roller is rotationally connected to the interior of the mounting base through a rotating shaft. The positioning effect is improved during punching and cutting, material deviation is prevented, correction is conducted in time when a watchband hunches up, the punching and cutting precision is prevented from being affected, and orifices are repaired after punching is completed.

The utility model relates to the technical field of finned tube rolling, and discloses a high-speed finned tube rolling device which comprises a supporting frame, a limiting rod is fixedly assembled on the outer wall of the supporting frame, a supporting ring is fixedly assembled on the outer wall of the supporting frame, an adjusting ring is rotationally connected to the outer wall of the supporting ring, and the limiting rod is fixedly assembled on the outer wall of the supporting ring. A moving rod is movably connected to an inner cavity of the supporting frame in a sleeved mode, a fixing plate is fixedly assembled on the outer wall of the moving rod, and a fixing frame is fixedly assembled on the outer edge of the moving rod. According to the high-speed finned tube rolling device, the supporting rings and the adjusting rings are arranged on the outer wall of the supporting frame, when the height and the position of an extrusion roller need to be adjusted, only the adjusting rings need to be rotated, the position of a moving rod can be adjusted under the action of the adjusting rings, and therefore the position of the extrusion roller is adjusted; and the outer wall of the extrusion roller is better attached to the outer wall of the metal pipe, and rolling of the metal pipe is achieved.

This invention provides a graded crushed stone paving device for road reconstruction subgrade, comprising a support assembly, a power assembly, and a material feeding assembly. The support assembly includes a conical box, which is fixedly connected to a material pipe. The conical box is connected to a U-plate, and the U-plate is connected to symmetrical long rods, which are respectively connected to guide blocks. The U-plate is connected to a motor bracket. The power assembly includes a motor, which is connected to a motor bracket. The output shaft of the motor is connected to a drive gear, and the U-plate bearing is connected to the central shaft of symmetrical driven gears. This invention relates to the field of road reconstruction technology, and particularly to a graded crushed stone paving device for road reconstruction subgrade. Addressing the shortcomings of existing technologies, this invention develops a graded crushed stone paving device for road reconstruction subgrade. This invention disperses and spreads graded crushed stone, allowing it to fall onto the subgrade surface, then disperses, vertically compresses, flattens, compacts, and rolls it to achieve graded crushed stone paving.
