In addition, in the embodiment, the fluidpressure controlling unit 50 is configured to deliver fluid pressure from one of thedrawing unit 30 and thetrimming unit 40 to the other one of thedrawing unit 30 and thetrimming unit 40. - Next, the operation of the press die composed as such is as follows:
- First, in a state that the
second die 20 is spaced apart from thefirst die 10 and in a state that the panel ‘P’ is placed on thefirst die 10 and thedrawing member 31, thesecond die 20 is moved toward thefirst die 10. - As illustrated on
FIG. 2 , when thedrawing surface 21 b of thesecond die 20 is arrived at the panel ‘P’ according to the movement of thesecond die 20, the fluidpressure controlling unit 50 delivers fluid pressure to thedrawing actuator 32. According to such, the panel ‘P’ is being held in between thedrawing surface 21 b and thedrawing member 31. - As illustrated on
FIG. 3 , in a state when the holding is completed, thesecond die 20 is continuously moved toward thefirst die 10 so that thesecond die 20 and thefirst die 10 are coupled to each other. As described above, the panel ‘P’ is in the state of being held in between thedrawing surface 21 b and thedrawing member 31, and thus the panel ‘P’ is deformed into the shape that corresponds to thefirst die surface 11 a and thesecond die surface 21 a. That is, the panel ‘P’ is subject to a drawing process. - After the drawing processing is completed, the fluid
pressure controlling unit 50 delivers fluid pressure from the drawingactuator 32 to the trimmingactuator 42. By the fluid pressure delivered to the trimmingactuator 42, the trimmingmember 41, as illustrated onFIG. 4 , is protruded toward thesecond core 21 and is entered through the trimminghole 11 b provided at thesecond die 20. However, since the panel ‘P’ having been subjected to the drawing process is interpositioned in between thefirst core 11 and thesecond core 21, the panel ‘P’ is cut into the shape that corresponds to the trimmingmember 41 and the trimminghole 11 b. That is, the panel ‘P’, after being subjected to the drawing process, is subjected to the trimming process. - As described above, the fluid
pressure controlling unit 50 is configured to selectively deliver fluid pressure to one of thedrawing unit 30 and thetrimming unit 40, and as such if the fluid pressure being delivered to thedrawing unit 30 and thetrimming unit 40 is made to be controlled by the fluidpressure controlling unit 50, thedrawing unit 30 and thetrimming unit 40 are operated while being interlocked to each other, and thus both of the drawing process and the trimming process may be performed on the panel ‘P’ even by only using small fluid pressure. - In the embodiment, the fluid
pressure controlling unit 50, as described above, is configured to deliver fluid pressure from one of thedrawing unit 30 and thetrimming unit 40 to the other one of thedrawing unit 30 and thetrimming unit 40, and thus both of thedrawing unit 30 and thetrimming unit 40 may be operated even through small amount of fluid pressure. - In the embodiment, the trimming
unit 40 is disposed at thesecond die 20, but the present disclosure is not limited hereto, and having the trimmingunit 40 disposed at thefirst die 10 may also be possible. - Although a few embodiments of the present disclosure have been shown and described, it would be appreciated by those skilled in the art that changes may be made in these embodiments without departing from the principles and spirit of the disclosure, the scope of which is defined in the claims and their equivalents.
