Description

Feeding rotary pressing arm device for metal plate processing Technical Field The invention relates to the technical field of metal plate processing, in particular to a feeding rotary pressing arm device for metal plate processing. Background In the production and processing process of the metal plate, the rectangular raw material plate with the corresponding size is required to be cut according to the product customization size, then the edges of the metal plate are bent through the feeding mechanism matched with the bending mechanism, the metal plate is bent into different angles and shapes, the bending of the metal plate in the process at least comprises bending the peripheral edges of the metal plate with the rectangular structure, the feeding mechanism is required to carry out material returning and feeding according to frequent requirements of the bending machine, in the process, the metal plate is required to be rotated to enable the side edges of the metal plate at different positions to correspond to the bending machine bending mechanism to realize bending operation, but the conventional metal plate feeding mechanism (for example, the model of radium gos AG-1500) is generally adopted to vertically press and fix the raw material plate to be processed, in such a way, when the conveying manipulator conveys the raw material plate to the feeding mechanism, because the upper part of the feeding mechanism presses the obstruction of the driving structure, the raw material plate can only be carried to one side of the feeding mechanism, then the raw material plate is transmitted to the pressing fixing position of the raw material plate of the feeding mechanism through the additional conveying structure, the processing efficiency of the metal plate is influenced in the process, the metal plate is easy to be stressed unevenly and inclined in the conveying process, the subsequent adjustment and correction of the angle of the metal plate by the calibration mechanism are still required (the mode of angle adjustment and correction is that the side edge of the metal plate is required to be parallel to the bending knife of the bending machine, the bending effect can be ensured), the processing precision of the metal plate is influenced, the traditional vertical pressing fixing structure is generally driven by a larger cylinder or other driving equipment (comprising pressing fixing and three hundred sixty-degree rotation) due to the larger volume, when feeding the metal plate to the bending machine, the feeding stroke is limited, because the driving structure with a larger volume is required to ensure that the driving structure with a larger volume cannot collide with the presser foot of the bending machine (the feeding mechanism and the bending mechanism are inevitably damaged when collision occurs), the method can be used for processing the raw plate with a larger size (for example, the raw plate with the length and the width of more than 50 cm), but is difficult for processing the metal plate with a small size (for example, the raw plate with the length and the width of less than 10cm or less than 20 cm).
