1. Introduction of Heavy industry

Heavy industry is the main means of production that provides material and technological foundation for each department of our national economy. Heavy industry corresponds to light industry. The department that provides the means of production is called heavy industry, and the department that produces the means of consumption is called light industry.

Heavy industry includes iron and steel industry, metallurgy industry, machinery, energy (electricity, oil, coal, natural gas, etc.), chemical, material and other industries. It provides all sectors of the national economy (including industry itself) with raw materials, power, technical equipment and other labor means and objects of labor, and is the material basis for realizing social reproduction and expanding reproduction.

The development scale and technical level of a country's heavy industry is an important symbol of its national strength. Now in the transformation of the automation industry in full swing, the heavy industry also takes high efficiency and high standards as the development goal.

2. Nanjing Decowell Remote IO application case in heavy industr

Nanjing Decowell has been deeply engaged in the field of industrial control for many years and has been recognized by many customers. At present, the products are widely used in 3C, new energy, medical, logistics, automobile, textile, packaging, iron and steel, mining, environmental protection and other industries. The following will bring you the application case of Decowell remote IO in the heavy industry:

3. Automatic stamping production line

The automatic production line is mainly composed of press, automatic feeding, monitoring and processing system and safety system. The press is mainly divided into eccentric double point and eccentric four point press. It adopts ultra-long guide rail and can be widely used in automobile covering parts, stamping parts and die manufacturing fields.

3.1 Production Line topology

The project uses Omron CJ2M series PLC, in which the pressure action mainly uses PLC logic to control the DC contactor to drive the hydraulic system action, in addition, through the intermediate relay to control the motor positive and negative rotation to drive the transmission chain, PLC part uses the DeviceNet bus communication, a single punching line uses 5 sets of Decowell EX card bus IO. The digital input and output point is about 200 points, mainly responsible for the sensor in place signal detection and drive relay and other related equipment.
