Description

Technical Field

[0001] The utility model relates to the technical field of metal bending processing, in particular to a metal bending device. Background Art

[0002] The bending and forming of metal sheets are carried out on a plate bender. The workpiece to be formed is placed on the plate bender, the brake shoe is lifted with a lifting lever, the workpiece slides to the appropriate position, and then the brake shoe is lowered onto the workpiece to be formed. The bending and forming of the metal is achieved by applying force to the bending lever on the plate bender. The minimum bending radius is a function of the ductility and thickness of the formed metal. For aluminum plates, the bending radius of the metal must be greater than the thickness of the plate. When bending, due to a certain amount of rebound, the bending angle of the metal must be slightly larger than the required angle. The bending of metal sheets is carried out in a metal processing workshop.

[0003] For example, a Chinese patent (CN204747136U) discloses a metal plate bending device, including a workbench, on which a pushing mechanism and a bending mechanism are arranged, and the bending mechanism is located in front of the pushing mechanism, and the pushing mechanism is used to convey the metal plate, and the bending mechanism is used to bend the metal plate. The metal plate is conveyed by the pushing mechanism, and when the metal plate reaches the specified position, the metal plate is manually pressed to position it, and the metal plate is pressed by the bending mechanism to bend the metal plate at the position corresponding to the front edge of the workbench. During the bending process, the metal plate is restricted by the front edge of the workbench and will not deviate, and the bending degree is uniform at each position, the bending is accurate, and the operation is convenient and safe.

[0004] The above scheme also has the following technical deficiencies: the above scheme is not convenient for clamping metal plates of different lengths; the above scheme uses manual pressing of the metal to position it, which results in a very labor-intensive processing process; and when the bending force required for the metal plate is large, it is difficult to clamp the metal plate manually; at the same time, the arm length of the human body is limited, so the above scheme is not convenient for clamping metal plates of different lengths. Based on this, a metal bending device is proposed. Utility Model Content
