A die is attached to the front of the ram so as to face the die.
By punching the material between the punch
Of the above punch in a pressure forming machine
The present invention relates to a mounting position adjusting device. [0002] 2. Description of the Related Art A die provided on a machine base and facing the die
Punch attached to the front of the ram that moves forward and backward
By forging the material between the bolts and nuts
Press forming machine for forming parts or various parts
In, in order to form a good product with good accuracy,
Before starting forging, adjust the mounting position of the
The centering adjustment is performed to match the axis of the die with the axis of the die.
However, the axis of the punch and the axis of the die must be completely
Even if the
By pushing into the center and pushing out the peripheral edge of the material

With the recess formed at the end of punching or at the tip of the punch.
Form a large-diameter head or the like at the end of the material between the front of the die
Parallelism of the material end face during upset processing
Is unevenly loaded on the punch due to variations in the hardness of the material, etc.
The punch acts eccentrically due to the weight acting on the molded product.
There was a risk that uneven thickness would occur and defective products would be formed. Further, a plurality of dies provided on a machine base and
Are mounted on the front of the ram so that they face each other.
Multiple forging stations are composed of
Out of these multiple forging stations
The forging load acting on one of the stations
If the ram is larger than the
As a result, the whole of the ram is slightly
Will also incline, so that the front of the ram
The mounted punch may be eccentric and a defective product may be formed.
there were. [0004] For this reason, during the above forging process,
The mounting position of the punch should be
It will be adjusted, but in that case the punch
As the mounting position adjusting device, for example, Japanese Utility Model 7-1564
No. 6 is known. In this gazette
The disclosed one has a sliding member on the front side of the ram.
It is supported so as to be able to move down, and on the front surface of the slide member.
The punch holder on which the punch is mounted is swingably supported.
The ram has two slide members and a punch holder.
While the punch holder
On both sides of the set bolt insertion part
Adjustment bolts are provided to rotate these adjustment bolts
The punch holder by moving
Swing the slide member in the left and right direction to punch
Adjust the mounting position of the punch fixed to the holder in the left and right direction
On the other hand, a base is fixed on the upper surface of the ram,
The tip of the base contacts the upper surface of the slide member.
When the positioning bolt that contacts and positions

Claims (1)

(57) [Claim 1] A predetermined material is formed by forging a material between a die provided on a machine base and a punch mounted on the front surface of a ram so as to face the die. A punch mounting position adjusting device in a press forming machine for forming a product having a shape, wherein a punch is mounted on a front side of a ram so as to be vertically movable, and a punch is mounted on a front surface of the slide member. Up / down position adjusting means having a first motor driven by an external operation while the holder is swingably supported, and driving the motor to move the slide member up / down via a first interlocking mechanism A second motor driven by an external operation; a left / right position adjusting means for swinging the punch holder in the left / right direction via a second interlocking mechanism by driving the motor; Actuated Having a first cylinder that, when the mounting position unregulated punch
Locks the ram and the punch holder and the slide member via the first pressing member by the first cylinder when co
In addition, when adjusting the mounting position of the punch,
The position of the slide member and the punch holder is shifted
And the first and second motors
The temporary member in which the slide member and the punch holder can operate.
Activated by lock means in lock state and external operation
When the punch mounting position is not adjusted
The upper portion of the second cylinder via the second pressing member.
Lock the punch holder and slide member on the ram side
Also, when adjusting the punch mounting position, the lock is released.
A punch mounting position adjusting device in a pressure molding machine, comprising: an auxiliary locking means to be removed .
