A bending machine is a mechanical equipment used for bending metal materials, which can bend metal sheets into different shapes and angles
Proper heating treatment can improve the quality and efficiency of bending for certain metal sheets that require stretching during the operation of the bending machine.
Below, we will introduce some common heating methods for bending machines.
1. Flame heating:
Flame heating is a traditional heating method for bending machines, which heats metal sheets by burning fuel to produce high-temperature flames.
The advantages of flame heating are low cost, high flexibility, and the ability to adjust the temperature of the flame according to the needs of metal materials and workpieces.
However, flame heating also has some drawbacks, such as high fuel consumption and uneven heating temperature.
2. Electric heating:
Electric heating is a heating method that converts electrical energy into thermal energy. It generates heat by passing current through metal materials to achieve heating.
The advantages of electric heating are high temperature controllability, fast heating speed, high heating efficiency, and no excess exhaust gas generated.
At present, electric heating has become one of the mainstream heating methods in the bending machine industry.

3. Laser heating:
Laser heating is a new technology that uses lasers to heat metal materials.
It scans the metal surface through a laser beam, converting laser energy into heat, thereby achieving heating of the metal material.
The advantages of laser heating are adjustable heating range, high heating efficiency, uniform heating temperature, and no deformation or heat affected zone on metal materials.
4. Induction heating:
Induction heating is a heating method that uses induced current to generate heat.
It conducts current by placing a coil around a metal material,
When the alternating current through the coil changes, induced current is generated in the metal material, which generates heat and heats the metal material.
The advantages of induction heating are fast heating speed, good temperature controllability, high heating efficiency, and no generation of exhaust gas and sparks.
5. Gas heating:
Gas heating is a heating method that uses high-temperature gas to heat metal materials.
It heats the metal material by spraying high-temperature gas or hot air onto the surface of the metal sheet.
The advantages of gas heating are high heating temperature, uniform heating, and accurate control of metal materials can be achieved by adjusting the temperature and flow rate of the gas.
