Description

Technical Field

[0001] The utility model relates to the technical field of precision leveling machines, and specifically relates to a feeding device for a precision leveling machine. Background Technique

[0002] A precision leveling machine is used for the correction of ultra-thin metal plates or the leveling of products after stamping. It is used for the leveling of coiled plates and is transferred to a punching press (or a feeding machine) for use in conjunction with a heavy-duty material rack. It can achieve the effect of automatic stamping. When leveling a product, the coiled material needs to be fed into the precision leveling machine through the feeding machine of the precision leveling machine.

[0003] After retrieval, the Chinese patent document application number 201820132475.X discloses a steel strip leveling and feeding machine, including a first bracket and a second bracket. An arc-shaped support plate is fixedly welded to the side wall of the reinforcing rib. A first rotating shaft is provided on the motor. A first belt pulley is installed on the first rotating shaft, and the first belt pulley and the second belt pulley are connected by a belt. Third rotating shafts are installed at both the upper and lower ends of the front end face of the second bracket. Arc-shaped clamping plates are installed on the third rotating shafts. A roller press wheel is installed at the right end of the arc-shaped clamping plate. A connecting block is installed on the third rotating shaft. For this steel strip leveling and feeding machine, the upper and lower air cylinders are respectively started to expand and contract to drive the upper and lower arc-shaped clamping plates to rotate, so that the roller press wheel at the right end of the arc-shaped clamping plate presses against the steel strip feeding roller to be fed sleeved on the four arc-shaped support plates. This not only ensures the flatness of the steel strip feeding, but also can adjust the expansion and contraction length of the air cylinder and the rotation angle of the upper and lower arc-shaped clamping plates according to the size of the steel strip feeding roller to be fed.

[0004] However, this device has certain defects. When blocking the material, this steel strip feeding device blocks the side of the steel strip coil by welding a triangular baffle on the side wall of the arc-shaped support plate to prevent side slip between the steel strips and affect the feeding. However, since the triangular baffle of this device is fixedly installed on the arc-shaped support plate and cannot move, the feeding device may only be able to uncoil a steel strip of one width and is not convenient for uncoiling and feeding steel strips of other widths. Therefore, we need to design a feeding device for a precision leveling machine to solve the problem that the device is not convenient for uncoiling and feeding steel strips of other widths.

During use, the coiled material is sleeved on the arc-shaped support plate connected to the rotating shaft. The first electric push rod is opened to move the baffle towards the direction close to the coiled material. Manually adjust the rotation position of the baffle so that the circular hole on the baffle can pass through the rotating shaft and the arc-shaped support plate to block the coiled material, and the protrusion in the circular hole will be inserted between two adjacent arc-shaped support plates to be stuck. When the rotating shaft rotates, the baffle will be driven to rotate without affecting the uncoiling.
