Fine control of the production process of roller chain

Fine control of the production process of roller chain: full management from raw materials to finished products

Overview of roller chain
Roller chain is a type of chain widely used in the field of mechanical transmission, with the characteristics of compact structure, light weight and high transmission efficiency. It is mainly composed of inner link plate, outer link plate, pin shaft, sleeve and roller. The inner and outer chain links can be relatively flexed during operation, the sleeve can rotate freely around the pin shaft, and the roller is sleeved on the sleeve to reduce the wear between the chain and the sprocket.

Fine control of production process

Raw material selection and management
Material selection: Select high-quality alloy steel or stainless steel as the raw material of roller chain to ensure that it has sufficient strength, wear resistance and fatigue resistance. For example, the rollers of standard chains generally use 10 or 20 steel. 20 steel is widely used in machinery manufacturing, with good mechanical properties and high strength.
Quality inspection: Strict chemical composition analysis and physical property testing of raw materials are carried out to ensure that they meet relevant standards and design requirements, and they can be put into use only after they are qualified.
Inventory management: Reasonably control the inventory of raw materials to avoid backlog or shortage. At the same time, ensure that the storage environment of the raw materials is dry and ventilated to prevent them from rusting or other damage.

Heat treatment process control
Quenching process: The parts of the roller chain are heated to a certain temperature and then quickly cooled to improve their hardness and strength. The control of quenching temperature and time is crucial. Too high or too low will affect the quality of the parts. For example, carburizing and quenching with No. 20 round steel can improve the toughness of the roller.
Tempering process: The quenched parts need to be tempered to eliminate quenching stress and improve the toughness and plasticity of the parts. The tempering temperature and time also need to be precisely controlled to achieve the best performance balance.
Equipment maintenance: Regularly maintain and calibrate the heat treatment equipment to ensure its normal operation and avoid heat treatment quality problems caused by equipment failure.

Cold processing process optimization
Mold management: Regularly check and maintain cold processing molds to ensure their accuracy and surface quality. Severely worn molds should be replaced in time to ensure the dimensional accuracy and shape accuracy of the parts.
Processing parameter control: During cold processing such as drawing, cutting and shaping, strictly control parameters such as processing speed, feed rate and cutting force to avoid scratches, cracks and other defects on the surface of parts.
Quality inspection: Strict quality inspection of cold-processed parts, including dimension measurement, appearance inspection and performance testing, to ensure that they meet design requirements and quality standards.
Assembly and debugging
Assembly process: Formulate a reasonable assembly process to ensure that the various parts of the roller chain can be assembled together accurately. During the assembly process, pay attention to the cleaning and lubrication of the parts to prevent impurities and dust from entering the chain.
Pre-tensioning treatment: Pre-tension the assembled roller chain to eliminate the initial gap between the parts, ensure that the load distribution of the chain is uniform, and improve its operating stability and service life.
Running-in test: Perform a running-in test to make the roller chain run for a period of time under a certain load and speed to run in the surface of the parts, reduce initial wear, and improve the fatigue strength of the chain.
Quality inspection and control
Inspection equipment and tools: Equipped with advanced quality inspection equipment and tools, such as chain length measuring instruments, tensile testing machines, wear testing machines, etc., to accurately test the various performance indicators of roller chains.
Process inspection: During the production process, each key link is inspected and monitored in real time to promptly discover and correct quality problems and prevent unqualified products from flowing into the next process.
Finished product inspection: A comprehensive finished product inspection is carried out on the roller chain after production, including inspections of appearance, size, performance, etc., to ensure that its quality meets relevant standards and customer requirements.

Packaging and transportation
Packaging design: According to the characteristics and transportation requirements of the roller chain, a reasonable packaging solution is designed. The packaging should have good protective properties to prevent the chain from being hit, squeezed and corroded during transportation.
Packaging material selection: Select appropriate packaging materials, such as cartons, plastic bags, wooden boxes, etc., to ensure that their quality is reliable and can meet the requirements of packaging and transportation.
Transportation management: Select reliable transportation methods and transportation companies to ensure that the roller chain can be delivered to customers safely and on time. During transportation, take protective measures to prevent the chain from being damaged.
