1 Improved Design of Stamping Die Stamping die life time is based on rational design.In stamping die design, engineers should give full consideration to form of mold,fixing method and guide form of concave convex die,determination of the pressure center and rigidity of lower plate.Especially for blanking die, gap value has a great influence on the
Influencing factors of precision terminal die life in different stamping process and external environment is various. Following comprehensive Analysis of the factors affecting die life in punching equipment and mold design: A. Punching equipment of precision stamping terminals It is vital to stamping die life time of the precision and rigidity of punching equipment. The
The chemical composition of steel is very important. The higher alloy composition of steel, the more difficult to machining. Metal cutting performance will be decreased when carbon content increase. Steel structure is also very important for metal cutting performance. Different structures included: Forged, cast, extruded, rolled and machined. Forging and casting parts surface are very
Forming method–can choose from two kind of basic material A) Hot working tool steel, it can afford high temperature during casting, forging and extrusive. B) Cold working tool steel, usually used for blanking, shearing, cold forming, cold extrusive, cold forge and powder pressure molding. Plastic–some plastic will producing corrosive by-products, such as PVC plastic. Condensation
In-die tapping is that a part manufactured out of brass is created using multiple stations in the stamping process. While the stations continue to shape the part as the material moves through the stamping press, holes are tapped to provide the threading necessary for the finished piece. Combining the tapping and progressive die stamping process
Because of different stamping process and different working conditions, the cause of precision stamping die burst can be in many ways. The following aspects of comprehensive analysis of the cause of mold burst: 1. The stamping die with bad raw material will broken in the subsequent processing.The life of molds with different materials is often
Precision progressive die design means the man who work on mold digital design in enterprise, including cavity die and cold stamping die, it can take full advantage of digital design tools, improve progressive die design quality and reduce the design cycle. Progressive die designer are proficient at CNC programming, progressive die 3D design, products R&D
Progressive die, which is composed of multiple work station, associates to complete different processing in sequence for each station, and finishes stamping process in one stroke. Material is pushed with a constant pitch by the punch feeder, and the die can complete multiple stamping processes including punching, blanking, bending, trimming, drawing and so on. 1.
Never maintenance stamping mold according the maintenance plan (1) Do not replace any spring. Damaged spring keep on working, which will lead to a skew of your block and damage the mold parts. using the spring of different sizes, different lengths at the same time will cause very poor spring pressure distribution. (2) Do not
