Abstract

PURPOSE:To easily adjust the wire habit by allowing a supporting body whose position can be adjusted in the vertical, and the left and the right directions to support a holder provided with a die so that the inclination can be adjusted through a spherical seat. CONSTITUTION:The wire habit adjustment is executed by adjusting nuts 22, e2 provided on a die box. That is, by screwing the adjusting nut 22, a supporting body 2 moves in the vertical, and the left and the right directions through a position adjusting bolt 21. Also, by screwing the adjusting nut 32, a holder 3 is oscillated through an inclination adjusting bolt 31. In this case, a spherical projecting part 30 of the holder 3 slides against a spherical seat 20 of the supporting body 2. As a result, an inclination angle of the holder 3 against the supporting body 2 is varied. That is, an inclination angle of a die 91 fixed to the holder 5 is varied. Thereafter, the wire habit of a metallic thin wire 90 is adjusted.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a dice box for holding dice.

[Prior art]

Generally, in order to draw a thin metal wire, the thin metal wire 90 is drawn in stages using five or more dies 91 as shown in FIG. is attached to the thin metal wire 90.

The die 91 is made of cemented carbide, diamond, etc., and is extremely hard.

However, due to long-term use, as shown in FIG.
1 may occur. in this case.

At the worn portion 911, the pull-out resistance decreases.

On the other hand, at a portion 912 on the opposite side of the worn portion 911, the pull-out resistance increases.

As a result, the wire diameter of the thin metal wire 90 changes, making it impossible to obtain the desired wire diameter and making it impossible to deform uniformly.
An unbalanced load is generated on the die 91, and the wire width of the thin metal wire 90 changes. At this time.

To measure the unbalanced load applied to the die 91.

As shown in FIG. 7, a load cell 95 is used.

The load cell 95 is a holder 9 in which a die 91 is arranged.
4 and the abutment member 96. The load cell 95
has a load sensor 950.

Then, the average drawing load applied to the die 91 is measured by the load sensor 950. However, in general,
Unbalanced loads cannot be measured.

In addition, the conventional dice box has 1 dice as shown in Figure 6.
The holder 94 is supported by a position adjustment bolt 97 with respect to a main body frame 98 so that its position can be adjusted in the vertical and horizontal directions. Then, the position of the die 91 is adjusted using the position adjustment bolt 97 to adjust the wire curl of the thin metal wire 90.

In addition, in FIG. 4, 92 indicates a feed roller, and 93 indicates a winding machine.

[Problem to be solved] However, in the conventional die box, it takes a lot of time to adjust the wire lineage of the thin metal wire.
Moreover, the adjustment required skill based on many years of experience.

Further, even if the wire curl is adjusted by -degree, the wire curl changes during wire drawing. Conventionally, it has not been possible to quantitatively control this change in line curl.

In addition, since the average pull-out load is measured using a load cell, it is not possible to determine whether the wear is occurring in the upper, lower, left, or right direction. Therefore, it is necessary for experts to set standards for wire length adjustment. It was very difficult to do.

In view of such conventional problems, the present invention enables easy line adjustment. It is intended to provide a dice box.

[Means for solving problems]

The present invention includes a main body frame, a support body supported by position adjustment bolts for vertical and horizontal position adjustment with respect to the main body frame, and a support body supported by a plurality of tilt adjustment bolts with respect to the main body frame.

and a holder on which a die is disposed, and the support body swingably supports the holder via a nine-spherical seat.

What is most noteworthy about the present invention is that the holder on which the die is arranged is supported in a tilt-adjustable manner via a single spherical seat on a support body whose position is adjustable in the vertical and horizontal directions.

The spherical seat may be provided on the support side (see Examples) or on the holder side.

The above position adjustment bolt and inclination adjustment bolt may be operated by screwing themselves, or may be operated by screwing an adjustment nut screwed into one bolt (see examples). is an adjustment tool for tilting the dice provided in the holder in any direction, such as forward, backward, or tilted.

In addition, it is desirable to attach a load sensor connected to a load measuring device to each of the multiple inclination adjustment bolts that support the holder. This will allow the uneven load that occurs on the die to be easily and continuously removed during the drawing process. can be detected. Examples of the load sensor include resistance wire strain gauges and semiconductor strain gauges.

[For production]

In the present invention, by operating the 1-position adjustment bolt, the support body is moved vertically and horizontally with respect to the 1-body frame.

Further, by operating the inclination adjustment bolt, the holder on which the die is arranged swings via the spherical seat. Such a spherical seat can swing the die in all directions. As a result, the inclination angle of the holder with respect to the support body changes in any direction.

Therefore, the wire to be drawn can be formed with any desired wire curl. Furthermore, even if the desired wire curl cannot be produced due to die wear or the like, it can be easily corrected by adjusting both of the adjusting bolts.

[Effect] In this way, in addition to adjusting the dice in the vertical and horizontal directions, it is also possible to adjust the inclination angle of the dice. That is, the degree of freedom in adjusting the dice is improved.

Therefore, according to the present invention, it is possible to easily adjust the line width. Dice box can be provided.
