Description

Technical Field

[0001] This utility model relates to the field of bending machine technology, and in particular to a novel irregular-shaped suction nozzle structure for bending machines. Background Technology

[0002] A bending machine is a machine capable of bending thin plates. Its main structure includes a support frame, a worktable, and a clamping plate. The worktable is placed on the support frame and consists of a base and a pressure plate. The base is connected to the clamping plate via a hinge. The base consists of a housing, a coil, and a cover plate. The coil is placed in a recess in the housing, and the top of the recess is covered by the cover plate. During operation, the coil is energized by a wire, which generates an attractive force on the pressure plate, thereby clamping the thin plate between the pressure plate and the base. Because electromagnetic clamping is used, the pressure plate can be made to meet various workpiece requirements, and it can process workpieces with side walls. Operation is also very simple. When bending sheet metal, a special-shaped suction nozzle is needed to remove any burrs or metal threads generated.

[0003] Currently, when irregularly shaped suction nozzles adsorb metal wires, the metal wires easily get tangled inside the nozzles, causing blockages and affecting the airflow rate, thus reducing their adsorption capacity. Utility Model Content

[0026] The effect achieved by the entire embodiment 1 is that, in actual use, multiple spiral guide vanes 7 are fixed on the inner wall of the suction pipe 1, so that when sucking up impurities, the two ends of the thin metal wire can slide upward along the spiral direction of the spiral guide vanes 7 inside the suction pipe 1 to the discharge port 2 under the guidance of the spiral guide vanes 7. The wire flows out through the arc-shaped guide surface 15 at the discharge port 2. The arc-shaped guide surface 15 is provided on the inner top surface of the discharge port 2, and the arc-shaped guide surface 15 is connected to the top arc surface of the spiral guide vane 7, which helps to guide the end of the metal wire.
