Shanxi Gu Debao Feng Heavy Industry Machinery Co., Ltd. is a high-tech company that researches roller CNC automation production lines, roller equipment, and roller technology. The "BCNAP-I type roller CNC automation production line" developed by the company is a result of its independent intellectual property rights.

The research and development results have been presented at industry conferences multiple times, receiving high praise from attending experts, who believe it is currently the most advanced roller production line and roller equipment in China. The report number is 201214B1917499, and the conclusion of the "Science and Technology New Report" is that it is the first of its kind in the country.

The core technology includes 4 specialized CNC automation processing centers, a CNC automation spraying line, 3 specialized 5-degree-of-freedom robotic arms, and Siemens S7-300 main station and other electrical engineering. It has 18 proprietary processes, has obtained 3 patent technologies, and has applied for 31 patent technologies. It has both on-site control and remote control functions.

Main technical features: high degree of automation, advanced processes, CNC processing, energy-saving and environmentally friendly, with a production efficiency 20 times that of conventional equipment. The patented roller produced by its spinning process has radial runout, axial movement, and resistance coefficient values that are 1/2 to 1/3 of the MT821—2006 standard, meeting the requirements set by relevant departments for the "Twelfth Five-Year Plan" period for high-speed, large-capacity belt conveyors' roller matching. It has the following innovations:

1. High precision.

(1) The roller shaft processing center uses CNC technology, producing finished shafts with an accuracy of ±0.02;

(2) Added a rust removal and roundness correction step for the roller skin, reducing the radial runout to 0.15, which is 3-5 times better than the standard.

2. The connection between the roller bearing seat and the roller skin uses spinning instead of welding (invention patent).

3. The main technical features of the roller skin CNC processing center:

(1) 3-station 4-point translational robotic arm.

(2) The roller skin boring uses multi-blade forming boring tools,

(3) Technology that rivets the bearing seat and tube together using spinning,

(4) Multi-tool concentric roundness processing technology for roller skin surfaces,

(5) The tube clamping and positioning device has a radial correction function, reducing radial runout.

4. The rotating double-headed 6-station roller shaft CNC processing center completes the processing of various forms of existing roller shafts, including grinding burrs in one go, achieving CNC and automation in roller shaft processing.

5. An automatic spraying process is used, with the roller skin being automatically loaded and unloaded by a 5-degree-of-freedom robotic arm in conjunction with a hanging conveyor chain; the hanging conveyor chain is equipped with self-clamping specialized lifting devices (patent).

6. An automatic shaft assembly machine uses an automatic shaft threading method (patent) instead of manual threading, which is a first in the industry.

7. The double-headed rotating 6-station CNC roller pressing center uses a double-headed rotating 6-station CNC pressing mechanism, cleverly solving the pressing of internal and external seals, bearings, and elastic retaining rings for shafts.
