Description

Idle die of pressing process.

The present invention relates to an idle die, and more particularly, to an idle die for continuous operation of a large-sized mold having a continuous process, Lt; / RTI >

For example, a door outer panel requiring roughly 5,000 tons or more of tactile force is separately press-molded. The door outer panel is formed by a process of drawing by a conventional press, a trimming process for removing an unnecessary portion of the product, A step of forming a door outer panel in the order of a step of f1anging for reinforcement of the product, a step of restriking for calibrating and a step of burring for increasing the hole, A curling process to a hemming process is added.

As such, the door outer panel is formed through seven processes including drawing, trimming, flanging, restriking, burring, curling and hemming. The door outer panel is formed by a light hand door outer panel (LH) (RH: Right Hand) Since the shape of the door outer panel is opposite, it takes a total of 14 steps to produce these two door outer panels. That is, it is general that the door outer panel takes a total of 8 steps.

In particular, when a plurality of dies are provided by a single press to perform the continuous process as described above, the load on the equipment is increased, which causes a cause of defects.

 As a result, the idle process is suitably inserted between the processes. In the idle process, the strength of the mold is increased, the time margin of thermal diffusion is adjusted, and the center of the press load is adjusted.

However, the mold to be installed in the idle process should be usually manufactured in a shape suitable for the outer shape or the molding shape before the idle process, which is inexpensive to manufacture a general mold.

In addition, in the case of press working such as bonnet, trunk and the like other than the door outer panel as an example, a different child die is required, which leads to an increase in manufacturing cost of automobiles.
