High frequency quenching application technology for sheet metal stamping dies
Published on:

As the market becomes more and more competitive, all molds will tend to be short cycle, high quality and low cost, and air conditioner type molds are no exception. For the air conditioner class projects such as chassis, outer cover, partition and other tensile forming molds, the heat treatment of forming plates currently used are heat treatment of the whole plate.
As the market becomes more and more competitive, all molds will tend to be short cycle, high quality and low cost, and air conditioner type molds are no exception. For the air conditioner class projects such as chassis, outer cover, partition and other tensile forming molds, the heat treatment of forming plates currently used are heat treatment of the whole plate.
Specific problems exist as follows:
As the forming plate is subject to heat treatment, the large template heat treatment of sheet metal stamping dies has high hardness, large deformation, long heat treatment cycle and high processing cost.
In order to solve the above problems, large forming type sheet metal stamping dies use high frequency quenching technology to partially quench the parts that need to be formed in order to meet the requirements of die use.
Before improvement: Heat treatment of the whole plate, long cycle time and high cost
After improvement: High-frequency local quenching of forming parts only, saving cost and shortening cycle time
