Description
Technical field
The present invention relates to a kind of warm forging of a kind of processing technology of plum coupling more particularly to plum coupling formings
Technique.
Background technology
Plum coupling is also paul pawl coupling, is most common connecting component in the transmission of engineering goods shafting.It answers extensively
For numerically controlled lathe, machining center, engraving machine, CNC milling machine, metallurgical machinery, mining machinery, petroleum machinery, chemical machinery, rise
The fields such as hoisting machinery, Transport Machinery, light industry and machinery, textile machine, water pump, wind turbine, air compressor machine have boundless market empty
Between.Existing plum coupling structure is made of two metal claw disks and an elastomer, and plum coupling is connected to two
Axis can generate vibration, which will be attached on elastomer, be converted into elasticity when two axis operate to shaft coupling inside
The elastic deformation of body, to reduce the impact to shaft coupling.The conventional machining process of plum coupling be by turning, milling and
Broaching etc. is formed using bulk heat treatmet after machine-tooled methods, this processing technology there is prodigious spillage of material and
Process-cycle is long, therefore is only suitable for small lot production.There is a kind of processing technology of plum coupling to be currently on the market
It casts, although this processing method can adapt to produce in enormous quantities, and can save spillage of material when processing, so
Casting shaft coupling can be fewer than mach shaft coupling many in product price, but ironcasting also has its disadvantage, due to equipment
It will produce larger torque either high speed on startup and generate claw in the case of crossing load and break the phenomenon that flies out, it is this
Situation can seriously threaten the life safety of equipment and operator, therefore require relatively high important events had better at some
Casting is not used.

With driven shaft shaft coupling, the strength and toughness for both having remained steel part also reduces mach allowance, and steel part passes through warm forging
Its institutional framework and mechanical property can be improved after processing, tied due to the deformation of metal and again after warm forging technique thermal processing distortion
Crystalline substance, so that original large dendritic crystal and columnar grain is become, crystal grain is thinner, isometric recrystallized structure of uniform size, makes steel part Central Plains
Compactings and the soldering such as some is segregated, is loose, stomata, slag inclusion, make its tissue become even closer, improve the plasticity and power of metal
Learn performance.In addition the fibr tissue of forging is consistent with forging shape, and metal streamline is complete, it is ensured that part has good
Mechanical property and longer service life, this be all casting it is incomparable.Simultaneously as driving shaft shaft coupling and driven shaft
The claw section of shaft coupling is by warm forging direct forming, and the concentricity of claw section and shaft coupling shank is high, almost no longer carries out
Machining.During to driven shaft shaft coupling just squeeze, a round rib is squeezed out on its head, even if shaft coupling
Claw broken also only to be wrapped around in driven shaft coupling to fly out and, to reach protection equipment and operating personnel
Purpose.

Specific implementation mode
The particular content of the present invention is described in detail in the following with reference to the drawings and specific embodiments.
As shown in Figure 1, the warm forging forming technology of plum coupling, comprises the technical steps that：Driving shaft shaft coupling 1 is selected
Material, blanking, ball blast, heating, to 1 head jumping-up of driving shaft shaft coupling, it is counter to driving shaft shaft coupling 1 be extruded into shape obtain as figure
The driving shaft shaft coupling 1 of shape shown in 1 forms four active shaft coupling claws 2, driving shafts in the upper end of driving shaft shaft coupling 1
The inside of shaft coupling 1 forms active shaft coupling axis hole 3 and active shaft coupling keyway 4, takes length, obtains driving shaft shaft coupling forging.
To 5 sorting of driven shaft shaft coupling, blanking, ball blast, heating, to 5 head jumping-up of driven shaft shaft coupling, to driven shaft join
Axis device 5 is counter to be extruded into shape and obtains the driven shaft shaft coupling 5 of shape as shown in Figure 2, forms four in the upper end of driven shaft shaft coupling 5
