[0002] During the processing of steel structure formwork, special semi-circular shapes are often required for edge beam drip groove formwork and bridge pier downspout reserved channel formwork. Currently, bending and stamping are commonly used to form steel plates. However, due to the different designs of drip grooves and downspouts between bridges, each formwork processing requires individual adjustment of the bending machine angle and replacement of the die press mold to achieve the required semi-circular shape specifications. This is time-consuming and labor-intensive, and the resulting arc-shaped steel plates are not precise enough to meet the design requirements. They need to be corrected and standardized one by one, which greatly affects the manufacturing efficiency of the formwork.

[0049] In some embodiments, the hand-cranked wheel screw workpiece clamp 2 includes a hand-cranked wheel 21, a horizontal plate 22, a vertical plate 23, a top block 24, and a screw rod 25. The first end of the horizontal plate 22 is connected to the outer wall of the second frame base 1, and the vertical plate 23 is installed above the second end of the horizontal plate 22. A screw hole is horizontally provided on the vertical plate 23. A through hole for the screw rod 25 to pass through is horizontally provided on the side wall of the second frame base 1.
