Material strip supporting mechanism for stamping

The invention relates to a material strip supporting mechanism for stamping. The mechanism comprises a lower mold base. The lower mold base comprises a concave mold cavity, bearing faces and at least two material strip supporting blocks. The concave mold cavity is arranged between the two bearing faces, or the concave mold cavity is surrounded by the bearing faces. The at least two material strip supporting blocks are movably arranged on the bearing faces and distributed on the two sides in the material belt conveying direction. The material strip supporting blocks can move to the position above the concave mold cavity or move to be separated from the position above the concave mold cavity on a bearing plane formed by the bearing faces. According to the scheme, when a material strip is conveyed, a supporting function can be provided for the material strip, balanced and stable running of the material strip is kept, when the material strip needs to be stamped, supporting on the material strip is removed, stampi
