The terminal pin is used for various heating pipe fittings. The main materials of this terminal pins are: iron, stainless iron, stainless steel; the characteristics of the terminal pins: small size, high power, uniform heat radiation, work, long service life, high hardness and high density.It is a basic component of mostly heating tube.
How to Solve the Problem of Loosening of the Terminal Pins in the Heating Tube?
The loosening of terminal pin is a serious quality problem, which directly affects the life of the whole machine and the safety of the user. The heating plates of baby bottle sterilizers and stew pots are generally small, and the assembly space is also small. The terminal pin must be bent and then welded to the insert. In addition, when the insert is twisted during assembly, then the terminal pin will loosen.
1. When the surface of the steel plate is treated after welding the insert, make a special polishing fixture to avoid the second correction of the lead rod.
2. During assembly:use special positioning fixtures to avoid excessive torque on the insert.
3. The terminal pin of the heating tube adopts the knurling structure to increase the friction force, and is not easy to loosen.
