To ensure on-time delivery to customers, production in Shandong Shankuang’s conveyor pulley workshop is proceeding steadily and efficiently. Multiple batches of pulleys have completed the full processing flow and are waiting for final inspection and warehousing. As the core transmission components of the belt conveyor system, every procedure is carried out solidly under the strict control of the staff, pursuing both production progress and product quality.
Raw material processing starts with precise cutting. Workers first inspect each sheet of selected high-quality steel one by one, eliminating blanks with surface rust, impurities or uneven material properties. Qualified raw materials are sent to CNC cutting equipment for accurate blanking according to preset structural dimensions. After cutting, the specifications of each component are verified one by one, and special tools are used to finely polish the edges to remove cutting burrs and sharp corners, ensuring accurate component dimensions and neat edges, laying a solid foundation for subsequent forming processes.
The cut steel plates enter the pipe body forming and welding stage. Operators use special plate rolling machines to roll the plates slowly in accordance with process requirements, calibrating the roundness point by point with templates during the process to avoid ovality or radian deviation. After rolling forming, the joints are accurately aligned, and sectional welding is adopted. Welding slag is removed promptly after each welding section, and welds are carefully inspected for uniformity and fullness. Any defects such as tiny air holes or slag inclusions are repaired immediately to ensure a firm structure and good sealing performance of the pipe body.
After welding, key surface derusting and impurity removal are carried out. Workers first use mechanical grinding to remove welding spatters and residual slag from both inside and outside the pulley pipe body, then adopt the shot blasting process to treat the surface comprehensively, thoroughly removing oxide layers, rust and various attached impurities. At the same time, the surface roughness of the pipe body is enhanced, creating favorable conditions for subsequent shaft head assembly and coating adhesion.
Precise control is implemented in the shaft head processing and assembly stage. Shaft raw materials first undergo quenching and tempering treatment to improve their comprehensive mechanical properties, ensuring sufficient toughness and load-bearing capacity in service. The tempered shaft blanks are then processed by precision turning on a lathe. Operators focus on controlling the journal accuracy and the perpendicularity of step surfaces, and frequently recheck dimensions with special gauges during processing to avoid dimensional deviations. Keyway milling is then carried out, followed by careful polishing of the groove walls and edges with files to remove burrs. Before assembly, the staff thoroughly wipes the joints of the shaft heads and the pipe body clean, applies special adhesive evenly, embeds the shaft heads accurately into both ends of the pipe body and fixes them compactly with tooling. After the adhesive is cured, bearings and seals are installed. Lubricating grease is applied to the inner rings of the bearings to ensure smooth rotation, and seals are carefully fitted to the gaps and compacted to effectively block the intrusion of dust and moisture.
Finally, the process enters surface treatment and quality inspection. Workers clean the entire pulley again and apply a wear-resistant and anti-corrosion coating evenly. The spraying angle is adjusted continuously to ensure full coverage and uniform thickness. After the coating is cured, fine sandpaper is used to polish tiny particles on the surface for a neat and smooth appearance. During quality inspection, workers check the appearance of each pulley one by one to confirm defect-free welds and intact coatings; rotate the pulleys to verify smooth rotation and check for abnormal noises; and inspect the firmness of the connection between shaft heads and the pipe body. Technicians conduct patrol spot checks to ensure every batch of finished products meets quality standards.
In the workshop, the sound of machinery running and tool operation blends in an orderly manner. Workers devote themselves to every detail, control each procedure with a rigorous attitude, guarantee product quality with solid craftsmanship, and fully ensure the delivery of qualified pulleys to customers on time, laying a solid foundation for the company’s fulfillment capacity.
