Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a deep bending holder with wedges in a deep bending tool for deep bending a work in a bending machine.

(Prior Art) Conventionally, a deep bending holder is, for example, a lower part of a vertically movable ram in a bending machine, an upper part of the holder is detachably attached with a bolt and a fastener, and a deep bending holder is mounted on a lower part of the holder. The upper part of the general-purpose tool, which is an upper mold, is detachably attached by means of bolts and fasteners. The holder is formed with a relief portion that is a deep bendable space portion, and when performing deep bending bending, the end of the work is located in the relief portion and does not interfere with the holder. It was possible to fold it.

Therefore, since the holder forms a relief portion and uses a general-purpose tool without using a tool for deep bending, it is inexpensive as a deep bending tool and can be manufactured in a light weight.
It was possible to use it repeatedly without being damaged after three times of use.

(Problems to be solved by the invention) By the way, even in this deep bending holder that uses a general-purpose tool, the bending angle accuracy may be required in deep bending of the work. At this time, it is necessary to adjust the entire height of the holder by using the shim, which requires a lot of labor for the adjustment work, and there is a problem that the adjustment is difficult.

SUMMARY OF THE INVENTION An object of the present invention is to provide a deep bend holder with wedges, which has a simple structure and can easily ensure the accuracy even when the bending angle requires accuracy in order to solve the above problems. .

(Means for Solving the Problems) In view of the above-mentioned problems of the related art, the present invention provides a "wedge capable of mounting an upper mold on a lower portion of a holder that can mount an upper portion on a lower portion of a ram in a folding machine. In the attached deep bending holder, a V-shaped relief groove is formed on the front surface of the holder in the left-right direction so that the front side is widened upward and downward in order to avoid interference with the end of the work. In addition, a wedge for adjusting the vertical position of the upper mold with respect to the holder is provided in the lower part of the holder so as to be adjustable in the left-right direction which is the width direction of the holder.

(Example) Hereinafter, an example of the present invention will be described in detail with reference to the drawings.

FIG. 1 is a front view of a deep bending holder with wedges, which is an embodiment of the present invention, and FIG. 2 is an enlarged view of a main part as seen from an arrow II in FIG.

A ram 1 provided on a folding machine (not shown) so as to be vertically movable.
The upper part of the holder 9 of the deep bending holder with wedges 7 is detachably attached to the lower part of the holder by the bolt 3 and the fastener 5. At the bottom of this holder 9, bolt 11
A general-purpose tool 15, which is an upper mold shown by a chain double-dashed line, is detachably attached by means of and the fastener 13.

The holder 9 is formed with an escape groove 17 in which the end of the work W is positioned without contacting the holder 9 when the work W is deeply bent. As is apparent from FIG. 1, the clearance groove 17 has an upper inclined surface inclined so that the front side (right side in FIG. 1) becomes higher and a lower inclined surface inclined so that the front side becomes lower. For the sake of convenience, the V-shape is formed so that the front side is widened in the upward direction and the downward direction, and is formed in the left-right direction (direction perpendicular to the paper surface in FIG. 1).

Further, a wedge 19 is interposed between the general tool 15 and the bottom of the holder 9. The bottom of the holder 9 forms an inclined surface 23 parallel to the inclined surface 21 of the wedge 19,
Long groove 25 that is long in the left-right lateral direction XX provided in the holder 9
And the mounting screw 27 inserted into the long groove 23 moves the wedge 19 in the lateral direction XX and holds the entire height from the upper portion of the holder 9 to the lower portion of the general-purpose tool 15 in an adjustable manner. .

In this way, even when the bending angle requires accuracy,
The accuracy can be easily maintained without the accuracy of the work W coming into contact with the escape groove 17 and impairing its accuracy.

Therefore, when the bending angle in the conventional deep bending holder requires precision, the difficulty of adjustment, which had to be adjusted by the shim, is eliminated, and the wedge 19 with respect to the holder 9 in the left-right lateral direction X-X. The entire height dimension is adjusted and the position of the escape groove 17 is changed only by moving the work W. Therefore, the accuracy of the bending angle of the work W can be easily maintained.

It should be noted that the present invention is not limited to the above-described embodiments, but can be implemented in other aspects by making appropriate design changes.

[Effects of the Invention] As can be understood from the above description of the embodiments, the present invention is, in short, the upper part of the holder (9) which can be mounted on the lower part of the ram (1) of the folding machine. Type (1
In the deep bend holder with wedge that can be attached 5),
Formed on the front surface of the holder (9) in the left-right direction is a V-shaped escape groove (17) opened so that the front side is widened upward and downward in order to avoid interference with the end of the work (W). And a wedge (19) for adjusting the vertical position of the upper mold (15) with respect to the holder (19) in the lower portion of the holder (19) in the width direction of the holder (19). It is provided so as to be adjustable in a certain left-right direction.

As is apparent from the above structure, in the present invention, the escape groove 17 provided on the front surface of the holder 9 is formed in a V shape so that the front side is widened in the upward and downward directions. It is of course possible to avoid interference between the end portion of the work W and the holder 9 during deep bending of the work W, and it is possible to easily cope with the case where the distance between the bent portions of the work W changes. It is obtained (even when the distance between the bent portions of the work W in FIG. 1 is large, the upper surface of the escape groove 17 does not interfere with the end of the work W).

Further, in the present invention, the upper mold for the holder 9
Since the wedge 19 for adjusting the vertical position of 15 is provided so that it can be adjusted in the left-right direction which is the width direction of the holder 19, the vertical adjustment amount of the upper mold 15 is higher than that of the wedge 19 in the horizontal direction. Since it can be made small, the fine adjustment of the vertical position of the upper mold 15 can be easily performed.

In other words, since the wedge 19 is not adjusted in the front-rear direction but is adjusted in the left-right direction, the dimension in the front-rear direction can be kept small and the wedge 19 or the like interferes with the work W. Therefore, even if the distance between the bent portions of the work W is small, it is possible to deal with the problem.
