Description

Novel take off board slide wedge product location structure Technical Field The utility model belongs to the field of plate-removing wedges, and particularly relates to a novel plate-removing wedge product positioning structure. Background In conventional mold designs, the stripper cam insert is typically designed as a unitary structure. Although the design simplifies the manufacturing process of the die to a certain extent, the positioning accuracy of the design is easy to be problematic in the part forming process. Positioning accuracy generally uses guide nails to position, and the guide nails are common positioning elements used for ensuring that a material belt always keeps the correct direction and position in the stamping process, so that the dimensional accuracy of product parts is ensured. However, if the guide pin is installed during the reciprocating motion of the stripper cam insert, the reciprocating motion of the guide pin in the material belt can lead to the material belt to be torn, thereby affecting the smooth proceeding of the stamping process. Because the stripper wedge insert needs to reciprocate to finish operations such as stamping and forming, the stripper wedge insert which is integrally designed cannot be fixed with the guide nail inside, so that position deviation easily occurs in the stamping process of a material belt, and the dimensional accuracy of a product is seriously affected. Therefore, the above problems are to be solved. Disclosure of utility model The utility model aims to overcome the defects, and provides a novel plate-removing wedge product positioning structure, wherein a plate-removing wedge insert is divided into two layers, the plate-removing wedge insert at the upper layer is responsible for the reciprocating motion of a bending punch, the plate-removing wedge insert at the lower layer is responsible for positioning a product part, and the precision of the product part is greatly improved due to the positioning of a guide nail.
