Forming process of q345 corten steel

What is the new forming process of q345 corten steel? The following q345 corten steel processing manufacturers introduce the characteristics of q345 corten steel forming process in three aspects:

1. Process design features

The q345 corten steel using cold stamping process needs 3-6 processes to form the required shape and size. Hot stamping can only be formed by one stamping, so the part shape design must fully consider its process characteristics. For the middle channel parts with deep stamping depth and difficult forming, cold stamping pre stamping can be used first, and then hot stamping.
2. q345 plate mold characteristics

1) The thermal expansion and contraction effect of q345 corten steel needs to be considered when designing the mold surface, and a specific thermal compensation scheme is adopted.

2) The design of the internal cooling circuit of the mold should fully consider the size of the cooling aperture, the spacing and arrangement of the cooling holes, the distance between the center of the cooling hole and the mold surface, and the flow of cooling water.

3) Consider mold division and precision assembly technology.

3. Changes in positioning technology

For cold stamping, positioning pins are often used to locate the blank. For hot stamping, in order to minimize the premature contact of the blank with the die surface before stamping, in order to reduce the temperature drop and improve the hot stamping formability of q345 corten steel products, a special support mechanism is required to support the blank.
