The invention discloses flanging and bending equipment for a metal plate shell of a range hood. The flanging and bending equipment comprises an equipment body, a product positioning tool, an upper pressing cutting die assembly, a lower pressing cutting die and a lower overturning cutting die assembly, wherein the product positioning tool, the upper pressing cutting die assembly, the lower pressing cutting die and the lower overturning cutting die assembly are mounted on the surface of the body. An auxiliary feeding assembly and a rear auxiliary feeding assembly of the product positioning tool are used for feeding and fixing. Left and right mounting supports are located on the left side and the right side of a to-be-machined metal plate and used for clamping the metal plate. A bending upper cutting die of the upper pressing cutting die assembly is located at the upper end of the bent edge of the fed to-be-machined metal plate and used for pressing the upper portion of a to-be-bent line. The lower overturning cutting die assembly rotates the to-be-bent edge upwards. According to the flanging and bending equipment for the metal plate shell of the range hood, the bending line position of the metal plate can be accurately adjusted, and the bending precision of metal plates made of different materials is guaranteed.

Metal plate bending machining forming device
ActiveCN113414253APrevent slidingGuaranteed bending accuracyMetal-working feeding devicesPositioning devicesStructural engineeringMechanical engineering
The invention is suitable for the technical field of metal plate machining, and provides a metal plate bending machining forming device. The metal plate bending machining forming device comprises a fixing base and further comprises a bending mechanism, wherein the bending mechanism is installed on the fixing base, the bending mechanism comprises a bending assembly, an elastic pressing assembly, a driving assembly and an adjusting assembly, the driving assembly drives the bending assembly to bend a metal plate through telescopic movement, the adjusting assembly is used for changing the telescopic stroke of the driving assembly, and the driving assembly adjusts the bending angle of the metal plate by adjusting the telescopic stroke. A metal plate is placed on the bending assembly, the telescopic stroke of the driving assembly is adjusted by controlling the adjusting assembly, then the bending angle of the bending assembly to the metal plate is controlled, and when the driving assembly drives the bending assembly to bend the metal plate after adjustment is completed, the bending assembly drives the elastic pressing assembly to limit the metal plate, so that the metal plate is prevented from sliding in the bending process, and the bending precision is ensured.
