[0002] Steel plate is a flat steel material that is poured with molten steel and pressed after cooling. It is flat and rectangular and can be directly rolled or cut from wide steel strips. Steel plates are divided by thickness: thin steel plates <4 mm (the thinnest is 0.2 mm), medium and thick steel plates are 4 to 60 mm, and extra thick steel plates are 60 to 115 mm. Steel plates are divided into hot rolling and cold rolling according to rolling. The width of thin plates is 500 to 1500 mm; the width of thick plates is 600 to 3000 mm. Thin plates are divided into ordinary steel, high-quality steel, alloy steel, spring steel, stainless steel, tool steel, heat-resistant steel, bearing steel, silicon steel and industrial pure iron thin plates according to steel types; according to professional uses, there are plates for oil drums, enamel plates, bulletproof plates, etc.; according to surface coatings, there are galvanized thin plates, tinned thin plates, lead-plated thin plates, plastic composite steel plates, etc.

By making the two moving blocks 12 move relatively, the two ends of the steel plate are respectively inserted into the two slots 18, so as to fix the steel plate and improve the stability of the steel plate during the bending operation.

[0022] A moving mechanism for moving the two moving blocks 12 is provided between the two through grooves 9. The moving mechanism includes a double-headed screw 11 that penetrates and rotates between the two through grooves 9 and the side wall of the base plate 1. The two moving blocks 12 are respectively located on the outer walls at both ends of the double-headed screw 11 and are threadedly connected thereto. Two limit rods 10 are provided between the two through grooves 9. The two limit rods 10 penetrate the two moving blocks 12 and are slidably connected thereto.

[0023] Grooves 14 are provided at both upper and lower ends of the two through grooves 13, and sliders 15 are slidably connected in the two grooves 14. Two sliding rods 16 are provided between the two sliders 15 on the same side, and the two sliding rods 16 penetrate the movable plate 17 and are slidably connected thereto.
