Description

Technical Field

[0001] The utility model relates to a positioning clamping device of a U-shaped plate forming machine and the U-shaped plate forming machine. Background Art

[0002] Roll forming equipment generally includes a frame, two roller mounted wall panels and a shearing device. The two roller mounted wall panels are arranged at intervals on the left and right sides of the frame. A number of upper rollers and lower rollers are installed on the two roller mounted wall panels. The upper rollers and lower rollers cooperate with each other to squeeze and form the sheet. For thicker sheets, the rollers require greater force during the forming process, and the corresponding wall panels are also subject to greater reaction force. The wall panel may tilt, which will cause the bending angle of the folded edge of the formed sheet to deviate, resulting in defective products. Utility Model Content

[0006] The first limit block and the second limit block are arranged on the side of the two wall panels facing each other, and the first limit block and the second limit block are respectively abutted against the side of the two wall panels facing each other, so that the first limit block and the second limit block are limitedly matched with the wall panels along the direction in which the two wall panels approach each other;

[0009] In a preferred embodiment: the pull rod is a screw rod, and the first limit block and the second limit block are connected to the pull rod by bolts.
