Specific embodiment
Illustrate the contents of the present invention below in conjunction with specific embodiments.
Fig. 1 is 1 the schematic diagram of the section structure of upper junction plate in riveting process of the present invention, and Fig. 2 is riveting of the present invention
2 the schematic diagram of the section structure of lower connecting plate assembly in technique is connect, Fig. 3 is that the rubber mount 3 in riveting process of the present invention cuts open
Face schematic diagram, as shown in Figure 1-3, top connection board riveting process of the present invention is for assembling upper junction plate 11, lower connecting plate
Assembly 22 and rubber mount 33, comprising the following steps:
Step1: 1 electrophoresis painting of upper junction plate；Electrophoretic process, the electrophoresis mistake of the upper junction plate 1 are carried out to upper junction plate 1
The journey duration is 2min30s-3min30s, completes the attachment of paint film.Upper junction plate 1 after electrophoresis is first placed to dry, then will
Upper junction plate 1 is placed in drying oven, dries the surface of the paint film of upper junction plate 1.The in-furnace temperature of the drying oven be 170 DEG C-
180℃。
Step2: 2 japanning of lower connecting plate assembly；Electrophoretic process, the lower connecting plate assembly 2 are carried out to lower connecting plate assembly 2
The electrophoresis process duration be 3min-3min30s, complete the attachment of paint film.Lower connecting plate assembly 2 after electrophoresis is first placed
It dries, then lower connecting plate assembly 2 is placed in drying oven, dry the surface of the paint film of lower connecting plate assembly 2.The drying oven
In-furnace temperature is 170 DEG C -180 DEG C.
Step3: assembly upper junction plate 1 and rubber mount 3；Rubber mount 3 is inserted in the base recess of upper junction plate 11,
Using riveting at joint face, upper junction plate cushion assembly 4 is obtained.
Step4: assembly lower connecting plate assembly 2 and upper junction plate cushion assembly 4.By upper junction plate 1 and lower connecting plate
Assembly 2 is fixed by riveting, obtains the semi-finished product of riveting assembly product assembly.
Step5: welding.By the semi-finished product of the riveting assembly product assembly in Step4, in upper junction plate 1 and lower connecting plate
Repair welding is carried out at the joint face gap of assembly 2, obtains the finished product of riveting assembly product assembly.
Firstly, this technique use high temperature electrophoretic process upper junction plate 1 and lower connecting plate assembly 2 because vehicle use when
High fever can be generated by waiting inside, therefore higher to coating Capability Requirement resistant to high temperature, cooperate this kind of high temperature resistant to apply using high temperature electrophoresis
The drying temperature of layer.In Step1, electrophoresis time is limited, lower limit is to guarantee that the film thickness of electrophoresis is suitable, enhancing
It paints film strength.Its upper limit is being reached due to that can start to generate insulation when the paint film of electrophoresis reaches certain thickness
In the case where standard thickness, continuing electrophoresis will cause power consumption increase and waste, at this time for economic benefit, stop to continuation
Electrophoresis.First progress is basic before drying dries, this is to consolidate its structure to solidify the paint film surface layer of electrophoresis in advance,
When preventing drying, phenomena such as high temperature of drying causes coking to paint film surface layer.Temperature when drying is generally located on institute
10-15 DEG C or more of the coating drying temperature of use uses 170 DEG C -180 DEG C here.
Secondly, here in Step2 lower connecting plate assembly 2 electrophoresis process, the setting in reason and Step1 being provided with
Be it is the same, on the electrophoresis duration, the electrophoresis time compared to upper junction plate 1 is longer, due to the structure one of lower connecting plate
As for fixing, corrosion may be bigger, promote its lower limit, here to promote the lower limit of its film thickness.
Compared to the prior art, the present invention carries out high-temperature electric using by upper junction plate 1 and lower connecting plate assembly 2 respectively
After swimming, then carry out the process of subsequent assembly.Being scheduled such that upper junction plate 1 and lower connecting plate assembly 2 all has well
Corrosion resistance, therefore directly upper junction plate 1 and lower connecting plate assembly 2 directly can be assembled, not needed again to dress
Riveting assembly product assembly after matching carries out electrophoretic process, and setting in this way reduces the electrophoresis work that product assembly is assembled in a riveting
Sequence splits into the electrophoresis process of upper junction plate 1 and lower connecting plate assembly 2, shortens the electrophoresis bond area to be carried out, can
Promote the deposit efficiency of electrophoresis.The process that first electrophoresis reassembles, the technique processing method carried out compared to the prior art are resistance to
Corrosive power is slightly promoted, and electrophoresis process is safer, and assembly is more convenient.And electrophoresis again after being assembled in original technology, out
It in the performance protection to rubber pad, is only capable of using low temperature electrophoresis, such power consumption is low, but will lead to the service life drop of product assembly
It is low.And the process that first electrophoresis of the invention reassembles then is that of avoiding this problem, anticorrosion and can influence to fill
Match, the paint film of high temperature electrophoresis is even more the service life and anticorrosion high temperature resistance for having greatly improved final products assembly.
About assembly, the present invention using first rivet weld again by the way of carry out final assembly, make assembly when installation more
Add stabilization, safety is also higher, moreover it is possible to reduce the rejection rate of assembly.
Before the Step1, upper junction plate 11 and lower connecting plate assembly 22 are pre-processed.By 11 He of upper junction plate
The surface of lower connecting plate assembly 22 derusted respectively, oil removing, then is rinsed with water clean surface, dries with a cloth drying.It does so
The paint film deposit efficiency of electrophoresis can be promoted.
Repair welding in the Step5 is using the high pressure welding of electricity.Compared to original projection welding process, the safety of the high pressure welding of electricity is more
It is high.
The bottom of upper junction plate 1 and the top of lower connecting plate assembly 2 are correspondingly provided with flange in the Step4, by upper connection
The flange of plate 1 and the flange of lower connecting plate assembly 2 are riveted and are fixed.
Obviously, various changes and modifications can be made to the invention without departing from essence of the invention by those skilled in the art
Mind and range.In this way, if these modifications and changes of the present invention belongs to the range of the claims in the present invention and its equivalent technologies
Within, then the present invention is also intended to include these modifications and variations.
