Abstract
The present invention provides a kind of rivet hot method, it is suitable for various parts, versatility are good, and makes the durability of heating coil good, guarantee the uniform of coil diameter, vertical press fitting and horizontal press fitting are applicable.It will be used for the pitch of the laps dogleg section coating diamond grit of the heating coil of heating element in advance, so that the heating part even spread of heating coil has the diamond grit coating of 0.3mm~0.5mm thickness, thermal part to be added is put into later in the heating space of corresponding heating coil and is heated, after being heated to predetermined temperature, another component carries out push operation relative to the component, so that two component rivet hot connections.
Description
Technical field
The present invention relates to the technical field of rivet hot, specially a kind of control shaft rivet hot method.
Background technique
Rivet hot is the technique that the connecting portion of two sections of metals is fixed together by improving temperature, existing rivet hot method
It is to cover asbestos gauge in the appearance of heating coil, achievees the purpose that coil and heated components insulate, heats therein one with this
A metal parts, since normal coil is wrapped up by asbestos gauge, so that the diameter of coil is big, so that entire heating element
Volume it is big so that small part clamping is inconvenient, further, since heating coil coats asbestos gauge, the wear-resisting property of asbestos gauge is poor,
So that the abrasion that part to be heated and asbestos gauge generate easily destroys asbestos, so that the durability of heating coil is poor, and by
After asbestos gauge package the diameter of heating coil be unable to ensure uniformly, its deflection it is big, therefore existing rivet hot is vertical press fitting,
It makes whole equipment occupied space big.
Summary of the invention
In view of the above-mentioned problems, the present invention provides a kind of rivet hot method, it is suitable for various parts, versatility are good, and make
The durability for obtaining heating coil is good, guarantees the uniform of coil diameter, and vertical press fitting and horizontal press fitting are applicable.
A kind of rivet hot method, it is characterised in that: the pitch of the laps dogleg section that will be used for the heating coil of heating element in advance applies
Diamond grit is filled, so that the heating part even spread of heating coil has the diamond grit of 0.3mm~0.5mm thickness to apply
Thermal part to be added, is put into the heating space of corresponding heating coil later and heats, after being heated to predetermined temperature, separately by layer
One component carries out push operation relative to the component, so that two component rivet hot connections.
It is further characterized by:
Diamond grit partial size for carrying out coating is 0.1mm~0.3mm；
The diamond grit is sprayed into the pitch of the laps dogleg section of heating coil by hot-spraying technique；
The heating coil is specially copper pipe material；
Another described component is that vertical pressure load connects relative to heating element；
Another described component is that Horizontal type pressure load connects relative to heating element.
After adopting the structure of the invention, by the heating part even spread diamond grit coating in heating coil, make
Significant change will not occur for the volume for obtaining entire heating coil, can be convenient for the processing of all size part, therefore its versatility is good,
And since the wearability of diamond grit is good, and component generation friction will not destroy diamond grit coating, so that heating
The durability of coil is good；Further, since coating is uniformly distributed, and diamond grit can wearability so that coil diameter is equal
Even, in actual operation, vertical and horizontal press fitting is applicable.
Specific embodiment
A kind of rivet hot method: it will be used for the pitch of the laps dogleg section coating boart boart of the heating coil of heating element in advance
Grain later will be to so that the heating part even spread of heating coil has the diamond grit coating of 0.3mm~0.5mm thickness
Heating element is put into the heating space of corresponding heating coil and is heated, after being heated to predetermined temperature, another component phase
Push operation is carried out for the component, so that two component rivet hot connections.
Diamond grit partial size for carrying out coating is 0.1mm~0.3mm；
Diamond grit is sprayed into the pitch of the laps dogleg section of heating coil by hot-spraying technique；Heating coil is specially
Copper pipe material；
Another component is that vertical pressure load connects or Horizontal type pressure load connects relative to heating element.
Its advantages are as follows:
1 present invention substitutes asbestos gauge diamond material, and uses spray form, is firmly covered on copper pipe,
It does not fall off；
2 coil good rigidities, are unlikely to deform, and occupancy is small in size, and diamond itself insulate, is wear-resisting, and be loaded part repeatedly, does not damage
Hurt coil；
3 coil high temperature resistances are more preferable, and it is primary to reach 10000 replacements.
Specific embodiment: the horizontal press fitting rivet hot of selector
Material of the red copper copper pipe of outside diameter 3mm as heating coil is prepared, is changed according to what is be pre-designed for heating
The size bending of lug-latch forms heating coil, turns around the gold that circle part sprays 0.3~0.5mm thickness using hot-spraying technique doubling
Hard rock sand grains, the diamond grit partial size of selection protect copper pipe, and achieve the purpose that insulation in 0.1mm~0.3mm, will
The heating coil is loaded on corresponding horizontal press mounting structure, proceeds as follows later:
A selector fills in selector clamping tool, and control shaft fills in control shaft clamping tool, and shift refers to that filling in shift refers to folder
Tight tooling；
B coil heats selector；
Laterally indentation shift refers to c control shaft；
D selector is heated between 780 DEG C -980 DEG C, and control shaft is pressed into selector, completes rivet hot.
This hot riveting technique is different from the existing rivet hot in market, and it is now horizontal rivet hot that common rivet hot, which is vertical rivet hot, saves empty
Between, multiple parts can be pressed step by step, accomplish once to be loaded, repeatedly substep is pressed, raising efficiency.In the process, add
The effect of heat coil is as follows:
1 heating selector, reduces indentation force value, selector is made first to heat expansion, then cooling meat, guarantee selector axle sleeve
With the enclasping force of axis, guarantee its torsion qualification；
2 because be horizontal press fitting, and coil is rigidly good enough, and no person is easily deformed, and leads to poor heating, diamond grit
Coating solves the problems, such as this；
3 because be horizontal press fitting, and clamping, coil will will inevitably be got well in feature contacts, wearability repeatedly, and no person applies
Layer falls off, and loses insulating properties, and diamond grit coating hardness is high, overcomes this defect；
4 because yield is high, repeatedly after clamping, it is ensured that its service life, diamond grit coating, heat-resisting performance solve well
Certainly this problem.
Specific embodiments of the present invention are described in detail above, but content is only the preferable implementation of the invention
Example, should not be considered as limiting the invention the practical range of creation.It is all to become according to equalization made by the invention application range
Change and improve etc., it shall still fall within the scope of this patent.
