11, reconditioning burrs: the processing of reconditioning burr is carried out using polishing machine;
12, play blaze knowledge: carrying out playing blaze knowledge processing using hydraulic press, mark content is selected according to drawing requirement With.
Further, the sanction material, can tailor any one in steel plectane material and aluminum alloy round plate, carry out steel Iron plectane material is tailored using blanking device or gas cutting profiler device, is carried out aluminum alloy round plate and is used stamping equipment.
Rotary press modelling carries out rotary press modelling processing, the mechanical performance of steel plate using spinning machine cooperation spinning mold core Good, intensity is big, has by forming wheel surface surface smoothness with higher and surface hardness, spinning machine worktable after squeezing Sliding sleeve can be vertically moved up or down sliding on guide rod, push stretching for piston rod to provide power for sliding sleeve by cylinder, on spinning machine Three stretchings are completed, first is to make blanking on spinning machine to be drawn into cylindrical workpiece for the first time, and second is by first The wheel blanks with machined surface profile are drawn into the secondary cylindrical workpiece being drawn into, third road is to stretch second The blank drawn preliminary molding wheel regular at outer surface again.
Spinning machine has shaft, that is, has the function of rotation while being pressed downward, that is, can be rotating downwards Pressure, is not in this way buckling phenomena in compressed steel material plate, presses out that part is more smooth and beautiful, and the part wall thickness of forming is equal Even, profile is more able to satisfy required precision.
The spinning mold core is divided into two parts, outer die casing and interior Membrane cover, is respectively arranged below end and the sliding sleeve of sliding sleeve Workbench on, spinning mold core is molding die, and in actual use, hollow space in interior Membrane cover carries out spinning behaviour Make, when shaping the wheel at different slots bottom, removes the bolt of fixed outer die casing Yu interior Membrane cover, then remove outer die casing and interior Membrane cover Replacement, the mode for replacing Membrane cover is simple, meets different product processing, can save manpower, the time be saved, to improve Efficiency.
Membrane cover is made of damping material, so that Membrane cover quality itself is lighter, further saves manpower, whole process only needs It wants a people and the shorter time is spent to can be completed, but also the process of replacement Membrane cover not will cause mechanical damage, Ke Yiyou Effect increase equipment service life, replace Membrane cover after, do not need to do excessive debugging again, reduce waste material generation, increase yield rate, It saves material.
Resistance of deformation is bigger than common process by 20% during rotary press modelling, and corresponding forming force also increases 20%;Steel Material has biggish springback capacity in processing, determines in mold design and technological parameter and takes corresponding measure to reduce and compensate Rebound, the coefficient of resilience presses 0.15% when expanding mould designs.
Rotary press modelling processing, obtains rotary press modelling wheel, the wheel of such spinning monoblock type can be to avoid original wheel Spoke and wheel rim weld the solder skip of generation, weld partially, and size of current acts on wheel, so that burn-through, fusion penetration occurs in wheel It measures the problems such as big, present spinning is in monoblock type, a series of problem that can come to avoid welded bands.
By rotary press modelling wheel press machine on rushing bolt punch die, rush bolt hole processing, here rush bolt hole Mold is divided into upper mold and lower mold, while being also equipped on upper mold and lower mold and rushing bolt hole blade mould, and two molds can To carry out position adjusting, to facilitate calibration.
The wheel initial material for punching bolt hole is placed on beveler, bolt hole chamfering processing is carried out;Chamfering is completed Wheel initial material carries out the processing of sanding thorn.
The air holes processing, the wheel of steel material are carried out rushing air holes processing, the wheel of aluminum alloy materials with stamping equipment Milling air holes processing is carried out with milling air holes equipment, chamfered then is carried out to air holes, raw material are not in air holes protrusion, wind The bad problem of hole crackle, air holes position degree,
Expanding shaping is that the good wheel blank of rotary press modelling is put into expanding shaping mould, carries out one side expanding, on one side It flattens, achievees the purpose that shaping;Make inside workpiece all preferably under multi-dimensional stress state, at this moment the mecystasis of material It is good, it is easier to be plastically deformed, is in other words exactly to be easiest to achieve the purpose that shaping;Expand a pressure by one, by preceding processes Produced internal stress eliminates, and resulting internal stress be also it is least, achieve the purpose that high-precision form simultaneously With preferable service performance and service life.
Valve port notch is milled, wheel blank is placed on workpiece positioning plate and is positioned wheel blank by locating piece, while oil Cylinder drives the vertical stroke feeding of milling cutter, so that wheel blank is milled out notch, the smooth nothing of valve port finished surface is pulled, intensity Height, original valve port are to carry out stamping process using perforating press, can generate valve hole week burr, modification, so as to cause When installing valve cock, valve rubber pad can be made damaged, generate gas leak phenomenon, present milling valve port is not in similar asks Topic.
Flatness calibration, the wheel blank clamped is placed on the press bench of press machine, operating pressure machine to Lower pressure, the pressure size of application are 8000-12500KN, pressure size and down stroke size according to wheel blank deformation shape The overproof size of condition, flatness, the compression strength of material, the factors such as thickness of part gradually slowly adjust, apply repeatedly, in adjustment Cold plastic deformation situation and grip conditions are paid close attention to, down stroke controls within 30-60mm.
Embodiment 2
Referring to Fig. 8-Fig. 9, the present embodiment the difference from embodiment 1 is that process integrated wheel using aluminum alloy materials, When tailoring of plectane material is carried out, the equipment used is hydraulic press punching press or cylindrical body is cut into plectane material, and air holes processing uses Milling air holes equipment carries out milling air holes processing, carries out wheel rim outer mold surface and inner mold using numerically controlled lathe after step 9 mills valve port Outerplanar working process in face and spoke.
