What is the production process of slewing bearing?
Slewing bearing is also called slewing ring or swing bearing. It has a wide range of applications in construction machinery, medical machinery and other industries, and is called "the joint of the machine". If you want to ensure the quality of the slewing bearing, you must strictly control each production process. Next we will introduce the production process of the slewing bearing.
The production process of slewing bearing
1. Steel raw material cutting
The raw material commonly used for slewing ring bearings is carbon-chromium bearing steel that is hardened as a whole, and the slewing ring is made of surface-hardened steel, generally made of 50Mn steel. First, the billet should be cut according to the expected size of the bearing, and the carbide saw blade with high hardness, wear resistance, strength and toughness should be used for cutting bearing steel.
2. Billet forging
The billet forging is to heat the billet in a heating furnace and forge it into a round cake shape. The purpose is to ensure the reliability and life of the bearing. After the raw material is forged, the bearing ring blank is formed.
3. Forging ring
Using a ring rolling machine, the steel billet is forged into a ring-shaped steel ring. Through forging, the internal structure of the steel can be improved, so that the steel material has more strength, plasticity and impact toughness.
4. Rough turning
Put the steel ring after the ring into the machine tool, carry out rough turning, turn out various groove raceways, fix the steel ring on the gear milling machine, cut the teeth, and provide conditions for the later grinding machine processing.
5. Heat treatment
Heat treatment is also called quenching. Generally speaking, the heat treatment process is to carry out high temperature treatment on the bearing ring after forging and turning, which can affect the uniformity of carburization in the bearing ring and improve the wear resistance and hardness of the bearing.
6. Drilling
When drilling the mounting hole on the end face of the steel ring, pay attention to the center and cutting angle before opening the hole. You can choose a drilling machine, a hand-held electric drill and a hand-operated drill for operation.
7. Fine grinding
Fine grinding is to dress the fine parts of the bearing. Fine grinding can affect the rotation flexibility of the bearing and the machining accuracy of the bearing surface. The raceway surface of the steel ring is finely turned again to modify the deformation caused by the previous process.
8. Assembly and packaging
Assemble the processed parts; the assembled finished bearings are coated with anti-rust oil, sampled for quality inspection, packaged and packaged, and then enter the storage or sales process.
The above is the production process of the slewing bearing summarized by the editor. You must have a clearer understanding of the slewing bearing. In order to maintain the good performance of the bearing and prolong its service life, it is necessary to strictly control the procurement to ensure its quality is intact; pay more attention to inspection and maintenance during operation.
