Description

Technical Field [0001] The present invention relates to a height adjustment device for forging die,

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a height adjusting apparatus for a forging die for adjusting a height of a metal mold used in various processes of forging.

Generally, the method of applying a shock in a state in which a metal material is easy to form is called forging.

Most materials are high in firing at high temperatures and easy to process, so it is common to heat the material to be forged at a high temperature.

At this time, a mold used for forging is provided with a punch for applying a compressive force or an impact force to the material, and the punch can be adjusted to a fine height.

However, in order to adjust the height of the forging mold by the conventional technique as described above, it is necessary to disassemble the mold from the press machine, and then perform further processing to adjust the height of the punch, The height adjustment of the mold as a whole is not easy, and the adjustment of the height of the mold can not be accurately measured, making it impossible to perform fine adjustment.

Particularly, in the case of a mold in which various processes are simultaneously performed according to the progress of the press machine and the mold, the conventional control method as described above is extremely complicated and difficult.

In order to solve such a problem, Korean Patent Registration No. 0201558 discloses a punch which is coupled to a lower portion of a knockout pin penetrating a predetermined portion of a mold body in a vertical direction, an inclined surface formed on an upper surface of the punch and coupled to the knockout pin, A horizontally moving member formed on an upper surface of the elevating member so as to be linearly movable on the upper portion thereof and having an inclined surface which is in surface contact with an inclined surface of the elevating member on a lower surface thereof, And adjusting and confirming means for moving the horizontal moving member and confirming the height adjustment amount of the mold as a numerical value.

However, in the prior art, since there is no guide for guiding the horizontal moving member only in the lateral direction, the horizontal moving member is twisted in the left and right direction to move the horizontal moving member in the horizontal direction, So that it is difficult to precisely adjust the height of the mold main body.
