Introduction to the procedures and principles of precision stamping die assembly

Precision, dedicated to precision metal stamping and metal insert injection molding for more than 10 years. We can design and manufacture stamping and injection molds according to the different needs of customers, and apply them to internal production. The molds are self-produced and have a rich mold design. Manufacturing experience. Below we will introduce the procedures and principles of precision stamping die assembly. The key to the assembly of precision stamping parts is how to ensure that the relative positions of the convex and concave molds installed on the upper and lower mold seats and the various parts related to them can work normally when the mold is closed, and the workpiece that meets the product requirements can be punched . For this reason, it needs to be mentioned that all kinds of parts put into assembly must meet the processing requirements of all kinds of parts put forward by the assembly process. For example, for a fixed plate with multiple punches, the relative position, dimensional accuracy and step distance accuracy between the various holes must be consistent with the die and the unloading plate; the bolts and pins on the backing plate have a large gap through the holes. Drilling according to the size of the pattern, the upper and lower surfaces should be grounded strictly after quenching; the integral die installed on the upper or lower mold base, in addition to the various holes that meet the pattern requirements, bolts should also be processed Holes and pin holes are put into assembly after heat treatment and finishing. The mold bases and guide plates that need to be connected and fixed. The screw holes and pin holes on them should be drilled and matched according to the corresponding holes on the die during assembly. Hinge. Based on this, although the mold types and structural characteristics of precision stamping parts are different, the assembly methods and installation sequences used are also different, but the assembly principles that should be followed are the same. When assembling the precision stamping part mold, you first need to select the assembly reference part, use it as the assembly reference of the precision stamping part mold, and then gradually assemble other mold parts according to the reference part; the choice of the reference part depends on the structural characteristics of the precision stamping part mold; The guide plate that also serves as the unloading plate should be selected as the assembly reference part; the precision stamping part dies guided by the guide pillar usually use the concave die as the assembly reference part; the blanking and punching compound die selects the pusher plate as the assembly reference part, and It is a prerequisite that the output center/center point of the pusher plate is aligned with the center/center of the mold handle. After the reference parts are selected, the various parts of the precision stamping die are first assembled into an assembly according to the individual connection relationship between them, and then the precision stamping die is assembled using the reference parts as the assembly reference.
