Second embodiment
The embodiment of the invention provides a kind of manufacturing methods of the compound leaf spring 100 of built-in type, for manufacturing first embodiment
In the compound leaf spring 100 of built-in type, compound 100 structure of leaf spring of the built-in type is simple, can be avoided stress concentrate caused by defect,
Bonding strength is high, and reliable and stable, light weight effect is good, and high temperature resistance is good, convenient disassembly.
The manufacturing method of the compound leaf spring 100 of the built-in type the following steps are included:
Step S101: manufacture insert 120, and insert 120 is pre-processed.
Specifically, step S101 includes two steps, is respectively as follows:
Step S1011: insert 120 is manufactured by 3D printing or mach mode.
It should be noted that manufacturing 121 He of connecting rod by 3D printing or mach mode first in the present embodiment
Two embedded blocks 122 obtain then by an embedded block 122, connecting rod 121 and another embedded block 122 successively welding fabrication
Insert 120.Specifically, by one end of connecting rod 121 the first plane 124 and the second plane with an embedded block 122 respectively
125 welding, the other end are welded with the first plane 124 of another embedded block 122 and the second plane 125 respectively, to improve connection
Intensity guarantees uniform force.
It is worth noting that, in the case where manufacturing connecting rod 121 and two embedded block 122 by mach mode,
It needs to carry out roughening treatment to the surface of connecting rod 121 and two embedded blocks 122 respectively, its surface roughness is made to reach Ra12,
In the case where manufacturing connecting rod 121 and two embedded block 122 by way of 3D printing, do not need again to 121 He of connecting rod
The surface of two embedded blocks 122 is handled.
Step S1012: cleaning insert 120 using machine oil and alcohol, is sealed after dry.
It is worth noting that, there are two types of cleaning methods for tool in step S1012, two kinds in step S1011 are respectively corresponded
Processing method, the cleaning method of the insert 120 manufactured by way of 3D printing are to be cleaned twice using industrial alcohol first,
It is cleaned three times with 98% medicinal alcohol again；The cleaning method of the insert 120 manufactured by mach mode is to make first
It is cleaned twice with machine oil, then is cleaned three times with 98% medicinal alcohol.
Step S102: fibrous material is set around outside insert 120, forms precast body.
It is worth noting that, in step s 102, using Wrapping formed technology or three dimensional weaving technique by fibrous material
It is set around outside insert 120, two methods being capable of molded preforms.
Using Wrapping formed technology molded preforms, first by cleaned 120 clamping of insert to twining
On fixture, then deploy epoxy glue solution, using TG value 180 degree epoxy glue, then by carbon fiber or glass fiber
It gets one's things ready and carries out semidry method winding on tow creel.In the process, yarn sheet width is 4 millimeters, and heating temperature is 40 degrees Celsius, yarn
Group's number is 2, and mandrel rotation speed is 4r/min, and small vehicle speed is 20m/min.Tensile force is controlled by 4 pressure rollers of setting,
A tensile force acquisition was carried out at interval of 10 seconds.
Using three dimensional weaving technique molded preforms, establishment yarn uses 3k yarn, works out the cross of yarn
Af=0.1125 square millimeters of sectional area, urgent factor lambda=0.6 weaves h=2 millimeters of section value of flower, circumferential yarn beam n=300.
The stretch modulus Ef=100-300Gpa of carbon fiber, Poisson's ratio μ f=0.15-0.32.Axis yarn uses 6K-12k yarn, resin
Select the epoxy glue using TG value in 180 degree.The stretch modulus Ef=20Gpa of resin, Poisson's ratio μ f=0.25.
Step S103: resin material is filled to outside precast body using resin transfer molding technology, die sinking obtains leaf spring
Blank.
Specifically, step S103 includes two steps, is respectively as follows:
Step S1031: precast body is put into mold, and resin material is filled into mold, obtains injecting glue precast body.
It is worth noting that, during injecting glue, 30 degree of injecting glue temperature of setting resin transfer molding equipment, pressure
Injecting glue precast body is taken out to being opened after the completion of precast body injecting glue for 0.1Mpa.
Step S1032: vacuumizing injecting glue precast body, and is put into baking oven and is solidified, and obtains leaf spring blank.
It is worth noting that, during being vacuumized to injecting glue precast body, first on the surface of injecting glue precast body
Successively laying non-porous release film, ventilated membrane and vacuum bag carry out the envelope system of vacuum system, will then vacuumize in vacuum system
Below to -0.85Bar.By injecting glue precast body be put into baking oven carry out it is cured during, be arranged baking oven in temperature 120 to
Between 140 degrees Celsius, curing time is between 2 to 3 hours.
Step S104: processing and cleaning treatment are carried out to leaf spring blank, obtain the compound leaf spring 100 of built-in type.
Specifically, step S104 includes three steps, is respectively as follows:
Step S1041: slightly cutting leaf spring blank using numerical control processing and finish-milling, obtains intermediate blank.
It is worth noting that, slightly cutting out the compound leaf spring 100 of built-in type first with numerically-controlled machine tool in step S1041
Resemblance, the general outline cut out at this time is in 100 big 10 millimeters of each diverging direction leaf spring more compound than built-in type, then again
Finish-milling goes out the resemblance of the compound leaf spring 100 of built-in type, mills out the general outline come at this time and compares built-in type in each diverging direction
100 big 1 to 2 millimeter of compound leaf spring, as intermediate blank.
Step S1042: being roughly ground and refined to intermediate blank, and the compound leaf spring 100 of built-in type is obtained.
It is worth noting that, being roughly ground first using the sand paper of 600# to intermediate blank, then in step S1042
Intermediate blank is refined using the sand paper of 1200#, the surface of blank, obtains the compound leaf spring of built-in type among uniform treatment
100。
Step S1043: cleaning the compound leaf spring of built-in type 100 using alcohol, saves after dry.
It is worth noting that, the compound leaf spring 100 of the alcohol washes built-in type of 95% or more use is simultaneously in step S1043
It is dried, the surface for needing to prevent dust and impurity from falling on the compound leaf spring 100 of built-in type when dry.
The beneficial effect of the manufacturing method of the compound leaf spring 100 of built-in type provided in an embodiment of the present invention and first embodiment
Beneficial effect is identical, and details are not described herein.
These are only the preferred embodiment of the present invention, is not intended to restrict the invention, for those skilled in the art
For member, the invention may be variously modified and varied.All within the spirits and principles of the present invention, it is made it is any modification,
Equivalent replacement, improvement etc., should all be included in the protection scope of the present invention.
