Description

Technical Field

[0001] This utility model relates to the technical field of arc plate bending and forming device, and in particular to an arc plate bending and forming device. Background Technology

[0002] As attached Figure 1 The arc plate shown includes a base plate and support strips welded and fixed to both sides of the base plate. During the bending and forming process of the arc plate, the support strips may shift to both sides after bending due to factors such as the thickness and width of the support strips and the base plate, thus affecting the bending and forming effect of the parts. Currently, the support strips are usually manually tapped after forming to reset them. However, this increases the labor intensity and cannot guarantee the bending and forming quality of the parts. If a special bending jig is manufactured for this part, the manufacturing cost will be greatly increased, and there is a need for improvement. Utility Model Content
