Warm forging forming technology of plum coupling

Abstract

The invention discloses a warm forging forming technology of a plum coupling. The technology comprises the technical steps of performing material selecting, material feeding, shot blasting and heatingon a driving shaft coupling and a driven shaft coupling; upsetting head parts of the driving shaft coupling and the driven shaft coupling; reversely extruding to form the driving shaft coupling and the driven shaft coupling; and setting the length of the driving shaft coupling and the driven shaft coupling as requirement to obtain the forged driving shaft coupling and the forged driven shaft coupling. The technology has the advantages that the driving shaft coupling and the driven shaft coupling processed by the technology remain the strength and toughness of steel parts, and the allowance for machining is reduced; and the organization structure and the mechanical performance of the steel parts can be improved after the warm forging processing.

Description

technical field [0001] The invention relates to a processing technology of a plum blossom coupling, in particular to a warm forging forming technology of a plum blossom coupling. Background technique [0002] The plum blossom coupling is also called the claw coupling, which is the most commonly used connecting part in the shaft transmission of mechanical products. Widely used in CNC lathes, machining centers, engraving machines, CNC milling machines, metallurgical machinery, mining machinery, petroleum machinery, chemical machinery, lifting machinery, transportation machinery, light industrial machinery, textile machinery, water pumps, fans, air compressors and other fields , has a very broad market space. The existing plum blossom coupling structure is composed of two metal claws and an elastic body. The plum blossom coupling connects two shafts. When the two shafts are running, they will vibrate inside the coupling, and the vibration force will Attached to the elastic bo...

AI Technical Summary

Problems solved by technology

At present, there is still a processing technology of plum blossom couplings on the market that is cast. Although this processing method can adapt to mass production and can save material loss during processing, casting couplings will be more expensive than machine couplings in terms of product prices. There are much fewer processed couplings, but cast iron parts also have their disadvantages. Because the equipment will generate a large torque when starting up or the claws will break and fly out under high speed and overload conditions. This situation will seriously threaten The life safety of equipment and operators, so it is better not to use castings in some important occasions with relatively high requirements
