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 precision metal terminal inside the connector house is the core part of the connector, which will transmit voltage current or signal of the external power lines or cable to the corresponding contact element matching connector. So, contact structure must be good, stable and reliable contact force and electrical conductivity. Loose contact will exist in
Metal stamping is that use the punch press and stamping die to press external forces to the materials such as sheet and strip materials. It is a forming process method that produces plastic deformation or separation and obtains the desired shape and size. According to the process classification, it can be divided into two categories:
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
Various factors in the process of manufacturing has negative impact on the dimension of stamping parts. Moreover, the defective dimension will directly influence the assembling ability. So, tightest quality control process is very crucial. During the mass production, test devices and measurements are essential in the process control. First Article Inspection is indispensable before volume
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
The form and structure of the automobile connector are various. Automobile connectors are primarily made up of contact parts, shell, insulators and accessories. The four basic structures are indispensable. Contact parts are the most important parts of the auto connector to manage the electrical connection. It is composed of the contact of the positive and
