Energy-saving-operation recommending system

Abstract

The purpose of the present invention is to provide an energy-saving-operation recommending system that can calculate the energy consumption predicted to be consumed by the entire body of a rolling line, with high accuracy and with respect to a material to be rolled that is scheduled to be rolled next. The total energy consumption consumed by plurality of equipment during a step in which one material to be rolled is passed through the rolling line is calculated. The total energy consumption is divided by the width and the length of the material to be rolled prior to rolling, and energy consumption reference values, which define the energy consumption per width unit and length unit of the material to be rolled, are calculated. The energy consumption reference values are associated with the steel grade of the material to be rolled and the target post-rolling plate thickness, and stored. An energy consumption reference value that corresponds to the steel grade and target post-rolling plate thickness of the material to be rolled, which is scheduled to be rolled next on the rolling line, is acquired. The width and the length of the material to be rolled that is scheduled for rolling is multiplied by the energy consumption reference value, and an energy consumption prediction is calculated.

Description

technical field [0001] The invention relates to a bending press according to the preamble of claim 1 and to a method for bending workpieces with a bending press according to claim 8 . Background technique [0002] The selection and arrangement of tools in bending presses (also called flanging presses or bending machines) is largely performed manually and only partially assisted by a mechanical controller. For this purpose, a bending plan is specified which estimates the product-specific upper tool and lower tool as well as the theoretical position of the upper tool and lower tool. But what cannot be monitored is whether the tool is used or has been used in the machine. Additionally, tools may be installed in potentially dangerous locations that do not correspond to the process. [0003] However, the tool needs to be positioned precisely in order to carry out the bending process with high quality and to adjust the backstop fingers or the robot accordingly. Corresponding po...

Problems solved by technology

In the prior art, it was necessary to be able to position the tool precisely relative to the tool holder, which resulted in a complex and time-consuming equipping solution for the bending machine
