Die forging production line intelligent control system

Abstract

The invention discloses a die forging production line intelligent control system, and belongs to the field of automatic production line control. The system comprises a main station PLC, an upper computer, an expert database, a slave station PLC, a remote I / O, a frequency converter, a safety PLC, a touch screen, a heating furnace, a press machine, an edge trimmer, robots, a temperature detection unit, a logistics unit, a cooling unit and a safety unit. The main station PLC is connected with the upper computer through a TCP / IP protocol. The slave station PLC, the safety PLC, the remote I / O, thefrequency converter, the robot A, the robot B, the robot C, the heating furnace, the press machine and the edge trimmer are all connected with the main station PLC through a Profibus-DP. The touch screen is connected with the main station PLC through an MPI interface. The expert database is constructed to optimize and adjust the striking force according to different initial forging temperatures inthe machining process, so that the machining quality consistency is improved.

Description

technical field [0001] The invention relates to a die forging production line control system based on an expert database, which belongs to the field of automatic production line control. Background technique [0002] The processing technology of the titanium alloy die forging production line includes heating, forging and trimming and other processes. The common method adopted by most factories in China is to operate manually with a single machine and single control. There is no necessary connection between each equipment. After the workers put the forgings into the heating furnace to heat and keep warm, they then select the appropriate forging according to the red heat of the forgings based on experience. After the forging is completed, the forging is put into the trimming machine for trimming. The labor intensity of the workers is high and the degree of intelligence is low. A small number of factories have a high degree of automation and can realize automatic forging of fo...

Problems solved by technology

The common method adopted by most factories in China is to operate manually with a single machine and single control. There is no necessary connection between each equipment. After the workers put the forgings into the heating furnace to heat and keep warm, they then select the appropriate forging according to the red heat of the forgings based on experience. After the forging is completed, the forging is put into the trimming machine for trimming. The labor intensity of the workers is high and the degree of intelligence is low.

A small number of factories have a high degree of automation and can realize automatic forging of forgings, but the same forging force is used for all forgings, resulting in poor quality consistency of forgings

These two methods have problems such as poor consistency of forging processing quality and low processing intelligence, and cannot realize online monitoring of the processing process.
