In order to avoid excessive heat transfer between the supporting element and the blank, the contact area between them should be minimized. So far, there is no dedicated hot stamping die blank support device on the market.

[0004] When the device is in use, the blank is supported by the supporting rod, but the spring drives the supporting rod to move. When the supporting rod contacts the blank, the spring continues to drive the supporting rod to move, squeezing the surface of the blank, causing the surface of the blank to deform and reducing the use effect. Therefore, a hot die forging high-temperature blank supporting mechanism is proposed to solve the above problem. Utility Model Content
