Operation points of electric upsetting
Before the operation, the purple copper rod and the upsetting die are installed on the butt welding machine. After the upsetting end of the steel bar is desusted, it is clamped on the die, so that the end face of the steel bar is in contact with the copper bar, and then the power is connected for heating. When the end of the steel bar begins to have plasticity, the pressure is applied until it becomes the required shape. After cooling, the fixture is removed to complete the upsetting.
3. Main parameters of electrothermal upsetting of steel bars
The power-on time is generally 30s; When the diameter of the steel bar is 12 ~ 16mm, the stretching length is 30 ~ 35mm.
