Setup information generating device and method for punch press

Abstract

The present invention provides a setup information generating device for a punch press which can generate setup information on replacement of a punch and a die with compatible tools, that is, replacement among punches and dies identified by the same tool number and used for processing for the same shape and the same size and which can also generate setup information according to processing know-how or the like. The device has setup information generating means 48 for comparing a processing schedule with tool numbers in mounted tool information storage means 45 to generate setup information. The device has compatible tool registering means 38 for registering processing conditions such as material quality and board thickness and information on which of plural types of punches 81 and dies 82 identified by the same tool number are compatible as a punch 81 and a die 82 which meet the processing conditions are registered in accordance with inputs from an operation panel 46. In addition to performing the comparison of the tool numbers, the setup information generating means 48 checks the processing conditions contained in the processing schedule against the compatible tool registering means 38, and compares the obtained compatibility numbers of the compatible punch 8, and die 82 with the compatibility numbers stored in the mounted tool information storage means 45.

Claims

1. A setup information generating device for a punch press in which a plurality of punches and a plurality of dies can be mounted with replacement punches and dies prepared, and for which for any of the mounted or prepared punches and dies, replacement among plural types of punches or dies is possible for at least either the punches or dies identified by the same tool number and used for processing for the same shape and the same size, the setup information generating device generating setup information on replacement of the punches and dies, the setup information generating device being characterized by comprising processing schedule storage means that stores a processing schedule containing information on tool numbers of the punch and die required for processing, mounted tool information storage means that stores the tool numbers of the punches and dies mounted on the punch press, setup information generating means for comparing the tool numbers stored in the processing schedule storage means with the tool numbers stored in the mounted tool information storage means to generate setup information, and compatible tool registering means in which processing conditions such as the material quality and board thickness of a plate material to be processed and information on which of the plural types of punches and dies identified by the same tool number are compatible as a punch and a die which meet the processing conditions are registered in accordance with inputs from input means, and in that the mounted tool information storage means stores, in addition to the tool numbers, compatibility numbers that identify the plural types of punches and dies identified by the same tool number, and the processing schedule contains the processing conditions, and in that in addition to performing the comparison of the tool numbers, the setup information generating means checks the processing conditions contained in the processing schedule against the compatible tool registering means, and compares the obtained compatibility numbers of the compatible punch and die with the compatibility numbers stored in the mounted tool information storage means to generate setup information.

2. A setup information generating device for a punch press according to claim 1, characterized in that the compatible tool registering means has a menu that allows a plurality of selection contents to be displayed for each of items of the processing conditions such as material quality and board thickness and the compatibility numbers, and has a selection input function for allowing selections from the menu.

3. A setup information generating device for a punch press according to claim 1, characterized in that the plural types of punches or dies identified by the same tool number and used for processing for the same shape and the same size have different clearances between the punch and the die.

4. A setup information generating method for a punch press in which a plurality of punches and a plurality of dies can be mounted with replacement punches and dies prepared and for which for any of the mounted or prepared punches and dies, replacement among plural types of punches or dies is possible for at least either the punches or dies identified by the same tool number and used for processing for the same shape and the same size, the setup information generating method generating setup information on replacement of the punches and dies, the setup information generating method being characterized by comprising: storing a processing schedule containing information on tool numbers of the punch and die required for processing, in processing schedule storage means; storing the tool numbers of the punches and dies mounted on the punch press, in mounted tool information storage means;comparing the tool numbers stored in the processing schedule storage means with the tool numbers stored in the mounted tool information storage means to generate setup information;registering processing conditions such as the quality and board thickness of a plate material to be processed and information on which of the plural types of punches and dies identified by the same tool number are compatible as a punch and a die which meet the processing conditions, in compatible tool registering means in accordance with inputs from input means; andin addition to performing the comparison of the tool numbers stored in both the storage means, checking the processing conditions contained in the processing schedule against the compatible tool registering means and comparing the compatibility numbers of the compatible punch and die with the compatibility numbers stored in the mounted tool information storage means to generate setup information.
