Brief description of spiral couplers

Rotary couplers have good use-value in use, can be convenient for users in use, and can be operated by users during use. The working principle is relatively simple and does not require complicated procedures. Rotary fastener forging heating equipment, which is widely used for surface quenching of gears, shafts, crankshafts, cams, rolls, and other workpieces, to improve the wear resistance and fatigue fracture resistance of these workpieces. The rear half shaft of the automobile is surface hardened by induction heating, and the number of fatigue cycles under the design load is about 10 times higher than that of quenching and tempering. The workpiece material for induction heating surface hardening is generally medium carbon steel. Also, the fastener system is required to have fewer parts, simple installation, and easy disassembly. The bowl buckle is easy to connect, so it can be adapted to scaffolding for buildings and structures of various planes and elevations. It is economical and simple to process. The rotating fastener is composed of two sub-couplers, and the lower fastener in each sub-fastener is small The end is connected with a joint bolt, the big end is connected with an upper fastener with a notch and a thrust surface, and the two sub-couplers are connected by rolling and riveting, and rotating at any angle. To meet the special needs of some workpieces, low hardenability steels for induction heating surface hardening have been developed. Workpieces made of high carbon steel and cast iron can also be surface hardened by induction heating. The quenching medium is usually water or high molecular polymer aqueous solution.
