DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a method and an apparatus for cutting a workpiece in a turret punch press.

[0002]

2. Description of the Related Art Conventionally, a turret punch press 201 has
As shown in FIG. 7, a plurality of punches P are provided on a rotatable upper turret 203, and a plurality of dies D corresponding to the plurality of punches P are provided on a rotatable lower turret 205. Further, the work shooter 207 as a product unloading device approaches the lower turret 205 below the pass line PL where the work W is processed between the punch P and the die D hit by the ram 209 at the punching processing position. Position.

In the turret punch press 201, a mold composed of a small-diameter punch P and a die D has an inner peripheral portion A, a central portion B, and an outer peripheral portion C from the inside of the upper and lower turrets 203 and 205 to the outside. Three molds are mounted on each circumference. The middle-diameter mold is located at the inner peripheral portion A and the outer peripheral portion C, and two molds are mounted. The large-diameter die is located at the central portion B, and one mold is mounted.

In the above turret punch press 201,
The work W that has been punched by the multi-cavity nesting process is separated by a worker at a portion connected by a microjoint.

[0005] Alternatively, the micro joint portion is cut by the punch P and the die D on the outer peripheral portion C.
The work is taken out by a work shooter 207 of mm square.

[0006] Further, as disclosed in Japanese Unexamined Patent Publication No. Hei 6-114466, a notch 211 is formed at a lower portion of the outer peripheral side of an upper turret 203 as shown in FIG. An arm 215 is provided below the punch 213 mounted on the outer peripheral portion C of the upper turret 2.
The arm 215 is provided with an upper blade 217 serving as a cutting blade at a tip end thereof. This punch 21
The upper blade 217 moves up and down when the blade 3 is pressed by the ram 209, and the lower blade 219 provided on the lower turret 205.
And the micro joint is cut off in cooperation with.

[0007]

By the way, in the conventional turret punch press 201, the operation of cutting off the microjoint portion of the nested work W by the operator is simple and inefficient due to the heavy operation. There was a problem.

When the micro joint is cut by the punch P and the die D on the outer peripheral portion C, if the center of gravity of the product at the time of the cutting is not outside the position on the work shooter 207, the work shooter 207 is cut off. Will not be carried out even if is opened. However, since the distance from the mold of the outer peripheral portion C to the outer peripheral surfaces of the upper and lower turrets 205 is long, the distance from the inevitably separated product to the position on the work shooter 207 becomes longer.
The minimum distance S of the product that can be carried out by the work shooter 207 becomes longer. For example, a conventional turret punch press 201
In the case of (1), the minimum product length S is 130 mm, so that a small product such as 50 mm cannot be carried out by the work shooter 207. Therefore, there is a problem that the work shooter 207 is hardly used.

In the latter case, ie, the upper turret 2
The punch 213 with the upper blade is a custom-made product in the case where the upper blade 217 with the upper blade 213 mounted on the outer peripheral portion C and the lower blade 219 of the lower turret 205 are cut in cooperation with each other. Since the position of the upper blade 217 is eccentric from the sliding center of the punch 213 and the punch 213 with the blade is in a cantilever state, the clearance between the upper blade 217 and the lower blade 219 fluctuates at the time of cutting, so that cutting accuracy is deteriorated. There was a problem.

Further, the punch 213 with the upper blade is moved to the upper turret 203 because of the structure of the punch 213 with the upper blade and the necessity of adjusting the clearance between the upper blade 217 and the lower blade 219 as described above. There was a problem that the mounting work was rather troublesome.

It can be easily installed on the basis of functions and functions.

Further, even if the slider is moved up and down by the punch hit by the ram, the slider can be moved up and down along the guide member on the outer peripheral side surface of the upper turret. Does not become cantilevered with respect to the punch. For this reason, when cutting the work in cooperation with the upper cutting tool and the lower cutting tool, the clearance between the upper cutting tool and the lower cutting tool is not deformed, so that stable cutting is performed.

Further, since the upper cutting tool and the lower cutting tool can be positioned near the outer peripheral side surfaces of the upper and lower turrets, the minimum product size that can be cut out of the micro joint and carried out by the work shooter is further reduced. It becomes even smaller.

According to a third aspect of the present invention, there is provided a turret punch press according to the second aspect of the present invention, wherein the upper cutting tool comprises an upper blade or a punch for a shear. The lower cutting tool comprises a lower blade or a die for a shear.

Therefore, when the upper cutting tool and the lower cutting tool are the upper blade and the lower blade for the shear, the upper blade is easily mounted on the slider member, and the lower blade is also easily mounted on the lower turret.

As the punch 91, a shot pin 95 having a cutting blade formed on the lower end face is attached with a bolt BT so as to protrude downward from the lower surface of the slider member 73, and a sliding hole through which the lower end of the shot pin 95 is inserted. The pin guide portion 99 having the member 97 is constantly urged downward by the spring 101. The pin guide 99 is configured to be stopped at a predetermined height by a stopper (not shown).

A die 93 is used as a lower cutting tool.
It is attached to the lower turret 15 so that punching is performed in cooperation with the shot pin 95 described above.

With the above configuration, when cutting the micro joint, when the slider member 73 is lowered by the lowering of the punch 61 hit by the ram 29, the work W is placed on the lower surface of the pin guide 99 by the urging force of the spring 101. The plate is pressed by being pressed against the upper surface of the die 93.

Since the slider member 73 is further lowered, the shot pin 95 is lowered, and this shot pin 95
And the die 93 cooperate with each other to cut the micro joint.

As described above, when the upper cutting tool and the lower cutting tool are the punch 91 and the die 93, the upper cutting tool and the lower cutting tool are the upper blade 77 and the lower blade 87 as in the above-described embodiment. Although the mounting is not easy in comparison with the structure, the burr direction of the work W to be cut is the same as the burr direction of the work W by the normal punching performed by the turret punch press 1, so that deburring in a post-process is performed. Work becomes easy.

The present invention is not limited to the above-described embodiment, but can be embodied in other forms by making appropriate changes.
