Description

Technical Field

[0001] The utility model relates to the technical field of bending equipment, and specifically to a continuous bending device. Background Art

[0002] During the production process of sheet metal parts, the whole plate needs to be cut first, and then the cut plate is subjected to cold processing such as bending, stamping, welding, etc., and finally a sheet metal part is formed. The bending of the plate requires the use of a bending device. Its working principle is that two bottom molds are set on the plate bending machine, the plate is placed on the bottom mold, and the bending part is facing the upper die. The die is driven downward, and the plate between the two bottom molds is pressed downward by the die, and after the die is withdrawn, the plate bending process is completed.

[0003] In the prior art, there is a utility model with authorization announcement number CN210907515U, which discloses a metal sheet bending device, including a base plate, four corners of the top of the base plate are fixedly connected with columns, and the tops of the four columns are fixedly connected to the four corners of the bottom of the top plate, a hydraulic cylinder is arranged at the center position of the top of the base plate, the top sleeve of the first support rod is connected to the second fixing part, the top of the second fixing part is fixedly connected to the second mold, the bottom sleeve of the second support rod is connected to the first fixing part, and the bottom of the first fixing part is fixedly connected to the first mold.

[0004] However, this patent usually can only perform one bending at a time when performing a bending operation, that is, the pressing device contacts the plate and presses the plate to bend once after pressing down. When the plate needs to be bent multiple times, the pressing device needs to be lifted and adjusted, and then the pressing device needs to be used again to press down to complete the second bending. When the plate to be processed needs to be bent multiple times, the common bending device cannot achieve one-time pressing and forming, and it is necessary to repeatedly lift and lower the pressing device and repeatedly adjust the position of the plate, which makes the bending operation inefficient.
