[0002]

2. Description of the Related Art In processing such as bending a lead of a lead frame, required processing is performed using a die. In this case, the number of shots of the die is counted to check the degree of wear of the die. Management is performed so that the mold is replaced when a predetermined count is reached. The method of managing the number of mold shots is to manage the number of shots of each mold with a ledger, or to set a controller on the processing machine where the mold is set and operate the controller when setting the mold Then, a method of adding, storing, and managing the number of shots is used.

[0003]

The method of managing the number of mold shots using the controller of the processing machine has the advantage that it is easier and more reliable than the method using a ledger. In many cases, processing machines are generally used for multi-product production. For this reason, a large number of dies have been set and used in one processing machine. In such a case, there is a limit to the number of dies that can be managed even if the dies are managed by the controller attached to the processing machine, and a program must be added when adding dies. There was a problem.

When the number of shots of a mold is controlled by the controller attached to the processing machine as described above, the controller is effective when the mold and the processing machine in which the set is set correspond one-to-one. However, it becomes meaningless if one mold is used in common for a plurality of processing machines. Recently, the trend of high-mix low-volume production is increasing, and a mold is often used in common by a plurality of processing machines for efficient production. The present invention has been made in view of the above problems, and its purpose is to manage the number of shots of each mold reliably and easily even when handling a large number of molds, Die shot count management method that can be effectively used for various usage methods such as using a die in common for a plurality of processing machines, and machining using the same

DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of the present invention will be described below in detail with reference to the accompanying drawings. In the method for managing the shot count of a mold according to the present invention, a counter for adding the number of shots is attached to each mold, and the counter is machined when the mold is set on a machining machine and machining is performed. It is characterized in that it is attached to the machine and the shot number of the counter is added.
In FIG. 1, 10 is a mold, 20 is a counter, and 30 is a processing machine. Reference numeral 40 denotes a counter set unit installed in the processing machine 30. Although the mold 10 is used by being set at a press position on the processing machine 30, only the counter set section 40 is shown in the figure.

The counter 20 is formed as a single unit for displaying the integrated number of shots. The display unit 22 displays the integrated value of the number of shots numerically, a magnet 24 attached and fixed to the lower surface of the main body, And a connector 26 connected to a socket provided in the setting section 30. When the mold 10 is not used, the counter 20 attracts the magnet 24 to the mold 10 and supports it on the mold 10.

FIG. 2 shows the configuration of the counter set unit 40. In the drawing, reference numeral 41 denotes a substrate portion of the counter setting section 40, and reference numeral 42 denotes an attraction plate for attracting the magnet 24 when setting the counter 20. Reference numeral 43 denotes a board socket to which the connector 26 is mounted. The board socket 43 is attached to the suction plate 42
When the counter 20 is set at the position, the connector 26 is installed in a positional relationship where the connector 26 is just mounted. The board socket 43 is connected to the control unit 44 of the counter 20 and the electric system of the processing machine 30.

When processing is performed using the mold 10 of this embodiment, when the mold 10 is set on the processing machine 30, the mold 1
The counter 20 is removed from 0 and set in the counter setting section 40 of the processing machine 30 to start processing. FIG. 3 shows a state where the counter 20 is set in the counter setting section. The counter 20 set in the counter setting section 40 integrates and displays the number of shots for each shot of the processing machine 30. When the predetermined processing is completed, the mold 10 is detached from the processing machine 30 and the counter 20 is detached from the counter setting section 40. The counter 20 is attracted to the mold 10 by the magnet 24 and held.

Each time the die 10 is set on the processing machine and the processing is performed, the above operation is performed, and the number of shots is accumulated in the counter 20. In this way, the counter 20 attached to the mold 10 displays the total number of shots of the mold at that point in time, whereby the number of shots of the mold 10 can be managed. If the counter and the counter setting unit are shared by the dies and the processing machine for setting the dies, the number of shots of the dies can be surely managed when the dies are used in these processing machines.

The type of the counter attached to the mold 10 is not particularly limited as long as it is easy to handle as a single unit. 4 and 5 show another embodiment of the counter and the counter set section. 5 in FIG.
0 is a counter, 51 is a magnet attached to the lower surface of the main body of the counter, and 52 is a connection board provided in the counter set section. The connection between the connection board 52 and the counter 50 is performed by a connector 5 protruding from the back of the counter 50 as shown in FIG.
0a is inserted through the connection board 52. That is, the counter 50 of this embodiment is set by inserting the counter 50 from the front to the back of the counter setting section. In the case of the apparatus of this embodiment, similarly to the above embodiment, the number of shots of the mold can be managed by attaching the counter 50 to the mold.

According to the apparatus of the embodiment, since the counter is attracted to and supported by the mold, it is easy to check the number of integrated shots. In this manner, the degree of wear of the mold can be checked, and the time for replacing the mold can be accurately known. Also, counter 2
The fact that the counters 0 and 50 are attracted and supported by the molds by the magnets 24 and 51 allows the counter to be easily handled, which is a great advantage in terms of work. In the case of adding a mold, it is only necessary to add a counter, and the trouble of modifying a program can be eliminated. Further, the used counter can be reused. In the above embodiment, the counter set unit 40 is installed on the processing machine 30, but the counter set unit 40 does not necessarily have to be on the processing machine 30. The mounting position of the counter set unit 40 is not particularly limited as long as the integrated shot number of the counter can be added according to the shot number of the processing machine 30.
