Description

technical field [0001] The invention relates to the field of programming technology and algorithms, in particular to a method for optimizing the quantity of production line equipment based on minimum energy consumption and minimum time. Background technique [0002] With the rapid development of social economy, a large number of infrastructure constructions are in full swing, and the manufacturing industry, which was once backward in technology, is gradually moving towards the development of automation and informationization. At present, many die forging production lines in China have introduced technologies such as automatic loading and unloading, automatic forging, automatic detection, automatic control of heating furnace temperature, etc., which can greatly improve production efficiency. However, the full automation of the transfer control of the die forging production line is still at a relatively low level, and some enterprises still use manual operations, resulting in ...

However, the full automation of the transfer control of the die forging production line is still at a relatively low level, and some enterprises still use manual operations, resulting in low production efficiency

The die forging production line requires multiple parallel paths to realize the heating, forging, ring rolling, testing, etc. of the die forgings, and the processing time of large equipment such as heating furnaces, forging presses and ring rolling machines is long, and the time for the mechanical arm to transfer the workpieces to be processed is relatively long. Short, so it is particularly important to increase the number of large-scale equipment in the die forging production line. Once the time-consuming increase of large-scale equipment in the entire processing process and poor operation will greatly affect the efficiency of the entire transfer system, then it will make Increased energy consumption and increased time to process an entire batch of parts
