Description
Technical Field
The invention relates to a self-breaking detection device used after heat treatment of a high-strength steel wire.
Background
A spring is a mechanical part that works by elasticity. The part made of elastic material deforms under the action of external force and restores to the original shape after the external force is removed. Also used as a "spring". Typically made of spring steel. The types of springs are complex and various, and mainly include spiral springs, volute springs, plate springs, special springs and the like according to the shapes. Most of the current spiral springs are made of spring steel wires wound into a spiral shape. In order to increase the spring strength, the steel wire is heat treated.
The induction heating method is heavier and heavier in heat treatment at present. Induction heating is to generate current inside the heated material by means of electromagnetic induction, and the heating is achieved by means of the energy of these eddy currents. Which is a method of heating a conductive material such as a metallic material. It is mainly used for metal hot working, heat treatment, welding and melting. Induction heating does not require an external heat source, but rather utilizes the heated workpiece itself as a heat source, nor does this method require the workpiece to be in contact with an energy source, i.e., an induction coil. Accordingly, companies are increasingly using induction heating for heat treatment.
However, the steel wires subjected to the heat treatment by induction heating have a risk of self-breaking, and according to the report of domestic enterprises, these spring steel wires have a self-breaking phenomenon during storage and use.
