Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an out-of-line processing method and an out-of-line processing apparatus for a metal processing line applied to, for example, a line for processing a die of a machine tool.

[0002]

2. Description of the Related Art Generally, in a metal processing line for automatically processing a workpiece according to a plurality of processing steps,
For example, if special processing is required for only a limited part of the whole work flowing along the line, it is not economically feasible to incorporate that processing step into the line, so that processing must be performed outside the line. There are things you have to do.

[0003] For example, dies used in a turret punch press include a die having a circular shape corresponding to a punch (round R) and a die having a rectangular shape (shape S). There is a pin for determining the direction when setting the dies. There are two types of dies having such pins, one type called a standard product and the other type called a high-performance product.

[0004] As shown in Fig. 2 (c), a standard product is one in which a pin 103 having a circular end surface (diameter B) is simply press-fitted into a side surface of a die 102. The groove (width B) and the pin (diameter B) formed at each point are line-contacted at one point on each side as viewed from the end face of the pin.

On the other hand, as shown in FIG. 2 (a), a high-performance product uses a pin 3 having a large diameter (A> B) at the protruding portion from the die 2 and press-fits both sides of the protruding portion. The surface was cut parallel as shown in FIG. 2 (b) (distance B between cut surfaces). Therefore, when the turret was set in the turret, a groove (width B) formed in the turret and a pin (side surface) were formed. The distance B) is in surface contact with both side surfaces of the pin.

Comparing such a standard product with a high-performance product, the standard product occupies the majority of the dies with pins in terms of the number. Therefore, the standard product is completed after press-fitting the pin and working the holes corresponding to the punch. All are processed on a line until they are finished.

On the other hand, high-performance products are characterized by a high degree of precision in determining the orientation when setting them on the turret, but on the other hand, the standard products in which both side surfaces of the pin protrusions are cut require extra processing. In addition, since the number is only a small part of the die with pins, it is not economically feasible to incorporate the process of cutting both sides of the pin protrusion into the line. It must be removed and cut off both sides of the pin protrusion outside the line.

[0008]

However, in a conventional metal processing line of this type, the work once taken out of the line is separated from the ID used on the line until the work is taken out, so that the work is put back into the line. Therefore, when processing a workpiece that has been cut off on both sides of the pin protrusion outside the line through the punch and the corresponding hole until it becomes a finished product, the original line must be stopped. In order to process a limited number of high-performance products, there is a problem that the standard product processing line must be stopped.

An object of the present invention is to eliminate the above-mentioned problems of the prior art, and to perform a special processing only on a limited part of all the workpieces flowing along a line.
Only the work that requires the processing is taken out of the line once, the necessary processing is performed outside the line, and then the processing is returned to the line again and the remaining processing can be continued.
