Standard single-V numerical control bending machine lower mold convenient to assemble and disassemble

The invention discloses a standard single-V numerical control bending machine lower mold convenient to assemble and disassemble. The standard single-V numerical control bending machine lower mold convenient to assemble and disassemble comprises a mounting base and a lower mold body. A mounting groove is formed in the upper surface of the mounting base, and the inner wall of the mounting groove ismovably connected with the surface of the lower mold body. A cavity is formed in the lower mold body. The front face and the back face of the inner wall of the cavity are provided with through holes.Screw rods are movably connected to the inner walls of the through holes. The ends, close to the front face of the lower mold body, of the screw rods penetrate through the lower mold body and are fixedly connected with the surfaces of fixing rods. The surface of each screw rod is in threaded connection with a movable plate and a movable block, the movable plates are located on the back faces of the movable blocks, and the lower surfaces of the movable plates and the lower surfaces of the movable blocks are movably connected with the bottom of the inner wall of the cavity. By arranging the screw rods, the fixing rods, the movable plates, the movable blocks, convex blocks, plug pins and plug slots, the problems that as for bending machine lower molds on the current market, the assembly and disassembly processes are complex and time and labor are wasted are solved.
