Definition of EV Power Battery Before understanding the power battery welding, we first need to do a simple understanding of the new energy power battery. The power battery is the “heart” of the new energy vehicle and the main source of its power. The power battery is mainly a ternary material battery and a lithium iron phosphate
The press fit terminal is an interface used to connect camera equipment. It is usually round, like a fisheye, called an eyelet terminal. It can realize the transmission of video signals and usually supports high-definition video transmission. Press-fit terminals are widely used in security monitoring systems, cameras, smart home equipment and other fields. The Basic
Precision cold forging technology is a method of forming and processing metal materials using a cold forging process. In this technique, the material is forged at room temperature instead of heating the material as in traditional heating forging. With the continuous improvement of industrial technology and demand, precision cold forging technology has gradually become one
It is believed that many metal stamping factories do not know what process to use for forming small holes which smaller than the raw material thickness. There are products will need this kind of small holes, such as mobile phone handsets, earphone speakers, Bluetooth speaker nets, filters, heat sinks, etc. Below are the advantages and
Heju stamping worked out silver contact riveting parts in die technology in 2013. The riveting parts effect as contact and breakover for relay products. It is widely used in medical, communication, transportation, electricity, electronic and other fields. During stamping production, we must do concrete analysis for the undersirable effects, and then take effectural measures to
Metal stamping die jump crumbs means phenomenon that sheet should in the edge jump to die surface after finish blanking shear in high-speed production die.As one of the usual metal stamping bad phenomenon, The cause of jump crumbs phenomenon produce is various,some cause by bad die design, some cause by bad material, some cause by
A. From system point of view, as the aspects of stamping, die manufacturing, the structure and produce design project of in-die riveting should attach great importance to the role of practical experience and a practical solution to establish feasible die design. B. In-die riveting structure is complex, difficult to design, and cost highly, design cycle
The proper use and maintenance of progressive die is an important measure to prolong die life. The use of progressive die should pay attention to the following aspects: Ensure the balance and lifting of the upper die when the metal die is installed, prevent the overtilt of the upper mould leading to the rupture of
1.The radius of the bending process. Spring clip needs to bend for shape. If the radius of bending part is relatively small, the parts will produce a lot of stress. So for the sake of avoiding high stress, the bending radius should be as five times thickness as the material. 2. Stress concentration at the
