Description
Technical field
The present invention relates to spokes to manufacture field, more particularly to a kind of male and fomale(M＆F) truck spoke production technology.
Background technology
Spoke is a component in automotive wheel, plays the role of supporting wheel rim and carrying out installation with axle coupling.
It is the bowl of a circular Intermediate Gray mounting hole, it is circular flat that the spoke of truck, which is commonly installed hole position,.
Currently, steel wheel used in heavy truck and car, the installation position of spoke is flat, professional standard
In be defined as disc wheel.The structure of spoke is divided into equal thickness spoke and variable cross-section equal strength spinning wheel by manufacturing process
Two kinds of spoke.The design and processes of two kinds of spokes are all to ensure the intensity at spoke plane first to carry out structure design.Plane
The thickness at place is mostly 14mm and 16mm.Disk material is processed into the required height of wheel set by drawing process or spinning process
Degree and outer diameter.
In the stress of wheel product, under same load, the stress at center of circle position is maximum, is gradually dropped to the periphery by the center of circle
It is low.In traditional handicraft and product, carried out on the basis of the intensity at spoke bosom i.e. mounting plane.Relatively advanced
Spinning process will gradually be thinned according to stress outside circumference, be processed into the spoke of variable cross-section.
Spoke material used in wheel of truck is commonly Q235B or 380CL, the tensile strength of material be 380MPa~
The center thickness of 440MPa, variable cross-section spoke are 16mm~14mm, and when with axle Matching installation, contact surface is big, and installation is stablized；Card
The spoke of vehicle wheel can also use rolled products of ordinary high-strength material, and such as the wheel steel of 490CL or 540CL, rolled products of ordinary high-strength material is anti-
Tensile strength is 490MPa~540MPa, the center thickness of variable cross-section spoke is≤10mm when, the carrying of product assembly can be reached
It is required that still, exist because spoke centre is relatively thin, contact surface is small when installation, and fastening is unstable and easy to crack brings truck driving safety
Potential problem.
Invention content
In view of the above-mentioned problems, the present invention provides a kind of male and fomale(M＆F) truck spoke production technology, it is maximum in spoke stress
Male and fomale(M＆F) is produced on mounting plane, tightness is installed to increase spoke in wheel of truck, wheel is steady when improving truck operation
It is qualitative.
The technical solution adopted by the present invention is a kind of male and fomale(M＆F) truck spoke production technology, using rolled products of ordinary high-strength wheel
Steel manufactures variable cross-section equal strength spoke, produces male and fomale(M＆F) on the maximum mounting plane of spoke stress, specifically include following step
Suddenly：
A, cutting stock is carried out to material, tentatively material is cut, keeps its in disk form；
B, when processing process processing in back on discoidal material required reference pre-determined bit datum hole, specifically include
Center is pre-positioned hole and bolt indexing pre-determined bit two class of hole, and center pre-determined bit hole and bolt indexing pre-determined bit hole are located at finished product spoke
Centre bore in, can be by its complete resection when rushing centre bore；
C, discoidal material is processed by spoke shape using the method for rotary press modelling or drawing and forming；
D, the ventilation hole on spoke is processed, number and shape are processed by product requirement；
E, concave-convex muscle is extruded on the maximum mounting plane of stress of spoke using concave-convex mold；
F, bolt hole and centre bore are gone out on spoke, in this step, are rushed when centre bore that the center in step B is pre-
Location hole and bolt indexing pre-determined bit hole are cut off completely；
G, according to the required precision of wheel set, centre bore and outer circle to spoke carry out finishing processing, to meet product
Precision and tolerance.
In above-mentioned step, E and F sequences can be interchanged.Can pre-determined bit hole first be indexed according to bolt and center is pre-
Location hole goes out bolt hole and centre bore, and concave-convex muscle is extruded by concave-convex mold further according to the position of bolt hole；In order to avoid indentation
The pressure generated when convex ribs causes bolt hole the influence of deformation, we are preferred first to determine according to bolt indexing pre-determined bit hole
Position extrudes concave-convex muscle by concave-convex mold, is positioned further according to the concave-convex muscle of extrusion, go out bolt hole.
Further, concave-convex muscle is distributed between two bolts hole of spoke, just processing one between each two bolt hole
Concave-convex muscle.
Further, the wheel steel of material selection 490CL or 540CL, Tensile strength are 490MPa~540MPa, material
Material thickness is 7~8mm.
Production technology using the present invention, using rolled products of ordinary high-strength wheel steel, such as the wheel steel of 490L or 540L, manufacture becomes
Section equal strength rotary pressure spoke processes concave-convex muscle on the maximum mounting plane of spoke stress, enhances mounting surface with this
Intensity makes each force part of spoke that can meet carrying force request.Rolled products of ordinary high-strength Tensile strength be 490MPa~
540MPa, the center thickness of variable cross-section equal strength spoke are 7~8mm, and the thickness of product material can be produced by tradition in the present invention
The 14mm of product is reduced to 8mm, directly saves material and puts into 6mm, product weight about reduces 6kg/ parts.
Beneficial effects of the present invention：By carrying out concavo-convex design processing to the maximum mounting plane of spoke stress, increase
Spoke installs tightness in wheel of truck, wheel stability when improving truck operation；Reasonable material reduces spoke consumption
Material saves truck energy consumption.
