[0003] At present, most bending machines used for metal bending can only perform a single crease bending process each time when bending steel plates, so that most metal plates need multiple bending operations to press steel plates and other plates into parts of corresponding shapes according to the needs of the manufacturing process; therefore, the existing bending machines have the problem of relatively low bending operation efficiency. Therefore, the utility model designs a metal processing equipment with precise and efficient bending. Summary of the invention

[0007] Furthermore, the support seat is equipped with a limit plate assembly for limiting the angle range between the two hook-shaped dies; the limit plate assembly is located below the hook-shaped dies; the limit plate assembly limits the angle range between the hook-shaped dies to a certain extent.

[0008] Furthermore, the limit plate assembly includes a limit plate A and a limit plate B; the limit plate A and the limit plate B are both hinged to the inner wall of the support seat; a limit slide column is slidably fitted between the relative inner ends of the limit plate A and the limit plate B.

[0010] Furthermore, the two hook-shaped dies on the lower die hinge A and the lower die hinge B are slidably matched with a hinge plate assembly, and the hook-shaped die and the hinge plate assembly are slidably matched through a slide groove and a guide column; the function of the hinge plate assembly is to ensure that both sides of the intersection of the lower die hinge A and the lower die hinge B are in a flat plate state, thereby ensuring the flatness of the metal sheet when bending.

[0011] The utility model has the following beneficial effects:

[0012] The utility model uses the function of the lower die base assembly and the hydraulic jack. After the upper die performs a single bend on the metal sheet on the lower die base assembly, the hydraulic jack pushes the lower die base assembly upward, so that the two hook-shaped dies bend the two sides of the metal sheet again, thereby realizing the function of double bending and achieving the effect of improving the bending efficiency.
