There are forty-four coil spring machines and cutting spring machines of various specifications in the section of the cutting section. The equipment is simple, cold cut by alloy knife and manual operation. The proficiency of workers' technology determines the quality of the products, the noise is extremely high (more than 100dB), and the oil pollution is serious, which greatly pollutes the environment and harms the workers' body (especially hearing). The equipment of the section is simple to control, the AC motor drives the speed reducer, the energy consumption is large, the maintenance cost is high, the work is unreliable, and the quality of the product cannot be guaranteed. In the annealing, quenching and tempering sections, there are six annealing furnaces in the section, single power 100KW, resistance wire heating, relay control, simple control and low efficiency. Due to the backward control method, the product decarburization is caused from time to time, which increases the consumption of raw materials and increases energy consumption. There are two quenching furnaces and two tempering furnaces in the section, single power 90KW, vibration bottom type, relay control, transformer low voltage and high current power supply, resistance band heating, fan temperature adjustment. The production efficiency is low and the energy waste is serious. Because the feeding amount is controlled by the vibration frequency, the vibration frequency control is manually adjusted, the human factor component is heavy, and the product quality control is difficult. The surface treatment and packaging section has three lines of blackening, phosphating and electroplating. The power supply of each line is 45KW, 45KW, 20KW, resistance wire heating, small driving assistance, manual operation and simple control. People have high labor intensity, poor production environment, low efficiency, high energy consumption, and no environmental protection. The packaging of the section is fully manual and labor-intensive, especially manual handwriting and pasting trademarks, which reduces the grade of the product, low efficiency and high cost. In order to change the current status quo, new technologies and new equipment are adopted to ensure energy conservation, consumption reduction and efficiency.
