Claims

[Scope of utility model registration request]

In a facing hydraulic forming apparatus in which a hydraulic dome is placed on a polster and an inner and an outer are disposed above the hydraulic dome so as to be able to be driven separately, the hydraulic dome and a blank holder bracket on the outer are connected to each other. At least one of the blank holder brackets is formed from a common main body and at least one insert part removably fitted into the main body, and each of the main body part and the insert part of the blank holder bracket is in a coupled state. A facing hydraulic forming apparatus characterized in that a horizontal hole having the same axis is provided, and a connecting means having a rod that can be inserted into the horizontal hole and can move forward and backward is fixed to the punch bracket in the inner.
