Manufacturing technology of low voltage electrical appliances
It aims to improve the technological level of various specialties
The manufacturing of low-voltage electrical products involves a variety of professional processes, such as cold stamping, plastic forming, coil winding, contact welding, mold processing, SMT chip technology, etc., so the improvement of manufacturing technology of low-voltage electrical products is closely related to the improvement of these professional process levels.
High speed, automation and specialization of parts processing
Stamping parts account for a large proportion of low-voltage electrical parts, about 70%, so stamping parts processing plays an important role in low-voltage electrical production. To improve the production efficiency and quality of stamping parts, it is imperative to use high-speed automatic punch and multi position progressive die.
Plastic parts are important parts of low-voltage electrical appliances. They are fully automatic or semi-automatic thermoplastic or thermosetting injection molding machines, and adopt centralized feeding mode.
Automatic welding machines are widely used, with adjustable welding current, pressure and pulse period, controllable temperature and guaranteed welding strength.
automatic assembly
Automatic assembly technology is adopted for key parts with large production batch and strict technical requirements, such as thermal magnetic release and control electric core.
Online detection
The on-line detection equipment in the production process is the main gap between the manufacturing level of low-voltage electrical appliances in China and that in foreign countries. It is the main reason that affects the quality stability and consistency of electrical appliances, and it is also the direction of future technology development.
