Description

Plate curling device

Technical Field

The utility model belongs to the technical field of plate curling, and particularly relates to a plate curling device.

Background

The plate curling process is to use a die with an arc surface, and to make the plate attach to the arc surface of the die by performing operations such as hammering and bending on the plate, so as to process the planar plate into a curved surface shape with a certain arc surface.

When the plate is curled, the plate is required to be continuously fed in the direction of the die, and the plate is gradually attached to the outer surface of the die to form an arc-shaped surface under the action of external force. In order to enable the device to have enough processing capacity and adapt to processing of plates with larger width, the length of a die and a feeding mechanism of the plate curling device is generally designed to be longer, and the design mode can process plates with larger width, but when processing narrower plates, the plates are easy to shift left and right in the feeding process, so that the diameter dimension deviation of the curled plates in the axial direction is larger (for example, cylindrical parts are processed into conical cylinders), and correction adjustment is needed later.
