Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a data registration device for a mold used in a press.

[Conventional technology]

Conventionally, the molds used in presses need to be replaced every time the molded product changes, so the number of types of molds has increased in recent years as a result of high-mix, low-volume production.

In addition, the molds used for presses have different press adjustment and setting items such as die hide, balancer pressure, duct tension pressure, production speed, etc., depending on the die, so when replacing the die, the press machine's die hide etc. It is necessary to adjust the press adjustment setting items.

For this reason, conventionally, various data are registered for each mold on the mold data management side of the press body, and when the mold is replaced, this data is read out and various adjustments are made in accordance with this data.

[Problem to be solved by the invention]

However, with this method, when one mold is used in common by multiple presses, it is necessary to register data for the same mold in each press, resulting in a huge amount of data to be registered, which is inefficient and If a registration error occurred, there were problems such as damage to the mold when it was attached to the press.

Additionally, as the amount of registered data increases, the capacity of the computer that stores it also increases, leading to increased equipment costs and other problems.

This invention was made for the purpose of improving the above-mentioned problems, and provides a press mold data registration device that eliminates the need for data registration on the mold data management side of the press body by registering various data in the mold itself. This is what we are trying to provide.

[Means and effects for solving the problem] In order to achieve the above object, the present invention provides a data registration section in a part of a mold used for press molding, and stores various types of the mold in this data registration section. In addition to registering the data, the press side is equipped with a data detection and transmitter that reads data from the data registration section and transmits it to the press control device, so that the mold data management side of the press body can record data for each mold. This eliminates the need to register and manage various data in the press.When a mold is set in the press, the data registered in the data registration section is sent to the press control device, and each part of the press automatically operates based on this data. The present invention provides a data registration device for press molds that can be adjusted according to the following conditions.

〔Example〕

An embodiment of the present invention will be described in detail with reference to the drawings.

In the figure, reference numeral 1 denotes a mold used for pressing, which consists of an upper mold 1a and a lower mold 1b, and a data registration section 2 such as an IC card is provided on the bottom surface of the lower mold 1b.

As shown in Fig. 4, the data registration section 2 includes mold number data, press data such as die hide, balancer pressure, duct tension pressure, production speed, etc., and data stacker data such as side guide width and type of attachment to be used. Loading device data such as plate thickness and the like are stored for each mold 1.

Further, on the bolster 3 side of the press, a data detection and transmission device 4 is provided at a position facing the data registration section 2 of the lower mold 1b when the mold 1 is placed.
Various data read from the data registration section 2 are sent to the press control device 5.

A data management circuit 6 is provided in a part of the press control device 5, and various data inputted from the data detection and transmission device 4 are inputted to this data management circuit 6 via a data transmission/reception section 7. There is.

An adjustment sequence circuit 8 is connected to the data management circuit 6, and based on various input data of the mold 1, the adjustment sequence circuit 8 controls the actuators 10 provided in each part of the press via an output circuit 9. A signal is output, press adjustment such as die-hide, balancer pressure, duct tension pressure, etc., adjustment and setting of the setting section are automatically performed, and the adjustment position and pressure are detected one by one by sensors and adjusted from the input circuit 12. Feedback is provided to the sequence circuit 8.

In addition, various types of data input to the data management circuit 6 are outputted from the display circuit 14 to the data display device 15, so that the operator can check various data of the mold 1 on the data display device 15, and also input data. New data can be registered in the data registration section 2 from the device 16 via the press control device 5, and data can also be rewritten.

In the figure, 17 is a mold identification device that identifies the mold 1 carried into the press, and the signal detected by this mold identification device 17 is sent to the mold discrimination circuit 18 in the press control device 5 for mold discrimination. After the adjustment has been carried out, it is input to the adjustment sequence circuit 9 and the data management circuit 6, respectively.

Further, for the transmission and reception of signals between the data registration section 2 provided on the lower mold 1b and the data detection/transmission device 4, a non-contact method using light, magnetism, radio waves, etc. can be adopted in addition to a contact method using electric contacts.

Furthermore, by making the data registration section 2 removable from the mold 1, the data registration section 2 can be taken out from the mold 1 and the necessary data can be read out from a dedicated external data provided outside the equipment.
The data may be registered by the writing device 19, and in this case, in order to prevent the data registration section 2 of another mold 1 from being attached by mistake, the data from the mold identification device 17 and the mold in the data registration section 2 may be registered. Damage to the mold 1 can be prevented by providing an ink clock circuit that checks the No. data and prohibits the press operation on the press control device 5 side when the data does not match.

〔Effect of the invention〕

As described in detail above, this invention is characterized in that each mold is provided with a data registration section, and various data of the mold is registered in this data registration section.19 is an external data reading and writing device. .

Furthermore, there is no need to register and manage mold data for each mold on the mold data management side of the press body.

As a result, even if the number of molds becomes enormous, the amount of effort required to manage the molds can be significantly reduced, and the risk of damage to the molds due to registration errors can also be prevented.

Also, when a mold is set in the press, various data registered in the data registration section is read and input to the press control device, and each part of the press is automatically adjusted based on this data, so adjustments are made every time the mold is replaced. This eliminates the need for additional work, which reduces mold replacement time and improves productivity.
