Description
Technical field
The present invention relates to field of motor production equipment, in particular to are suitable for the coiling nozzle and its production method of coil winding machine.
Background technique
In motor production process, need for enameled wire coiling to be nested on the stator or rotor of motor, production process
That coiling nozzle movement is driven by coil winding machine, after enameled wire is passed through coiling nozzle, coiling nozzle draught line by enameled wire coiling
To motor rotor or stator wire casing on.Currently, the structure of coiling nozzle ontology generallys use ruby and stainless steel ontology
Combination；It is ceramic, several with wolfram steel and carbon steel alloy.But presence wears no resistance, ties above-mentioned technical proposal in use
Composition type is poor, is easily damaged magnet wire insulation layer and the technical problems such as service life is short.
Summary of the invention
It is good that the technical problem to be solved in the present invention is to provide a kind of wear-resisting properties, shaping structures quality height and service life
The long coiling nozzle and its production method suitable for coil winding machine.
In order to solve the above-mentioned technical problem, the technical solution of the present invention is as follows:
Suitable for the coiling nozzle of coil winding machine, including ontology, cable-through hole is axially arranged in the body central, the cable-through hole
Incoming line is arranged in left end, and line outlet is arranged in the right end of the cable-through hole；The incoming line, line outlet gradually expand shape outward
At horn mouth；The ontology material is high-speed steel；The cable-through hole, incoming line, line outlet surface layer be nitriding layer.
Preferably, the nitriding layer with a thickness of 0.1mm~0.2mm.
Preferably, the central region of the ontology also sets up the shaft shoulder for installing limit.
Preferably, the incoming line side of the ontology is also set up for installing the fixed pin hole used.
The production method of coiling nozzle suitable for coil winding machine, the production method include blanking, forging, normalizing, roughing,
Finishing, vacuum hardening, tempering, grinding and polishing, vacuum nitriding.
Preferably, the heating temperature of the vacuum nitriding is 510 DEG C~530 DEG C；The heating time of the vacuum nitriding is
6h~8h.
By adopting the above technical scheme, due to having used high-speed steel, by the both ends of cable-through hole be arranged bell mouth shape into
Line mouth, line outlet, and the surface layer of cable-through hole, incoming line, line outlet is disposed as nitriding layer.And by nitriding layer when passing through production
Thickness control in preset range so that the surface hardness of cable-through hole, incoming line, line outlet has reached 1300HV；It effectively improves
Coiling nozzle wearability and service life.
Detailed description of the invention
Fig. 1 is main view schematic cross-sectional view of the present invention.
Specific embodiment
Specific embodiments of the present invention will be further explained with reference to the accompanying drawing.It should be noted that for
The explanation of these embodiments is used to help understand the present invention, but and does not constitute a limitation of the invention.In addition, disclosed below
The each embodiment of the present invention involved in technical characteristic can be combined with each other as long as they do not conflict with each other.
As shown in Fig. 1, suitable for the coiling nozzle of coil winding machine, including ontology 1, in the central axial setting cable-through hole of ontology 1
2, incoming line 3 is set in the left end of cable-through hole 2, line outlet 4 is set in the right end of cable-through hole 2；When in order to reduce inlet wire and outlet
Frictional force, by incoming line 3, line outlet 4 gradually outward expand form horn mouth.1 material of ontology in present invention specific implementation
Matter is high-speed steel；And nitriding layer is disposed as on the surface layer of cable-through hole 2, incoming line 3, line outlet 4.Nitriding in specific implementation process
Layer with a thickness of 0.1mm~0.2mm；The present invention is embodied with a thickness of 0.15mm.
Coiling nozzle progress clamping is fixed to further facilitate, also sets up use in the central region of ontology 1 in specific implementation
In the shaft shoulder 5 of installation limit.It also sets up in 3 side of incoming line of ontology 1 for installing the fixed pin hole 6 used.By pin hole 6 with
Coil winding machine is attached, and coil winding machine drives coiling nozzle to move axially in reciprocal fashion when making rotating motion, through connection bolt.
The production method of coiling nozzle suitable for coil winding machine, the production method include blanking, forging, normalizing, roughing,
Finishing, vacuum hardening, tempering, grinding and polishing, vacuum nitriding.
The heating temperature of the vacuum nitriding is 510 DEG C~530 DEG C；The heating time of the vacuum nitriding is 6h~8h.
Cable-through hole 2, incoming line 3,4 surface of line outlet roughness R when being polished directly in present invention specific implementationa<
0.025.It is handled by using vacuum nitriding, so that forming nitriding layer on cable-through hole 2, incoming line 3,4 surface of line outlet；Nitriding layer
Hardness be greater than 1300HV.
It is produced in specific implementation process of the present invention using high-speed steel, high-speed steel has good toughness, is able to bear
Repetitive shocks.It is also convenient for needing to form different shape construction according to clamping simultaneously, by the way that bell-mouthed incoming line 3 is arranged
With line outlet 4, frictional force of the enameled wire in coiling is effectively reduced, by cable-through hole 2, incoming line 3,4 surface shape of line outlet
At nitriding layer, wearability of the invention is effectively improved, is improved service life.Simultaneously as nitriding layer has self-lubricating function, it will
Coefficient of friction when enameled wire coiling is effectively reduced, further lowers the abrasion to enameled wire, improves around line mass.
In conjunction with attached drawing, the embodiments of the present invention are described in detail above, but the present invention is not limited to described implementations
Mode.For a person skilled in the art, in the case where not departing from the principle of the invention and spirit, to these embodiments
A variety of change, modification, replacement and modification are carried out, are still fallen in protection scope of the present invention.
