Description
Technical field
The invention belongs to automobile manufacturing field, be specifically related to the manufacturing approach of the cross-country refitted car wheel hub of a kind of high-performance.
Background technology
At present, aluminium alloy wheel hub adopts the method for casting or die cast to produce usually, conventional cast moulding method; No matter be counter-pressure casting, low pressure casting or gravitational casting, all, the gas in the mold cavity can't be drained because of the high velocity turbulent flow motion of its alloy liquid filling die mould; And cause product blank institutional framework not fine and close, be easy to generate casting flaws such as loose, folder hole; Its manufacturing cost is high, and the energy and raw materials consumption are bigger.The mechanical property of product and the surface quality of foundry goods can not be fully up to expectations.
Adopt and forge and spin forming method, its precision form, clearer production technology have following significance: 1. efficiently utilize raw material, to clean environment; 2. with the environmental cost and minimum energy resource consumption of minimum, obtain maximum economic benefits; 3. meet the sustainable development and the ecological balance.Adopt forging and pressing and spinning forming process, make the mechanical performance of wheel hub obtain bigger raising, and, raw-material utilization rate can be reached more than 90%, save production cost 10% because of the blank loss of weight has reduced the cutting output of fine finishining process blank.
Summary of the invention
The objective of the invention is to: the manufacturing approach that the cross-country refitted car wheel hub of a kind of high-performance is provided; Improve the tensile strength and the shock proof intensity of cross-country refitted car wheel hub through forging and pressing and mould pressing, make cross-country refitted car wheel hub can adapt to the requirement of going under the field extreme environment.
The present invention realizes in the following manner:
(1) gets the raw materials ready: calculate the volume of required blank according to the wheel hub part drawing, aluminium alloy bars is cut into blank;
(2) clean blank, in the 80-100 that is placed with the pre-treatment medicament ℃ water, remove the impurity such as greasy dirt on blank surface;
(3) blank after will cleaning is put into electromagnetic induction furnace and is heated, and in 30 minutes, blank is preheated to 400 ℃--and 450 ℃ and be incubated 1 hour;
(4) rough forge: blank blocking under 800 tons forging press is become pie;
(5) mould and die preheating: forging mold is preheated to about 300-350 ℃;
(6) before the forging and pressing; On die-face, spray graphitic lubricant, have manipulator to put into counterdie the rough forge blank that heats, through electrothermal tube to mould and blank heating; Make blank temperature remain on 300-350 ℃; Let the blank under the condition of high temperature under 1200 tonnes of forging presses, forge and press 2-3 time, each forging and pressing want pressurize just to open patrix afterwards in 10 seconds, make the wheel hub preliminarily forming;
(7) take out above-mentioned forging, put into and accomplish the enlarging operation on the enlarging forcing press of the little tonnage of 3.5MN;
(8) blank of enlarging and shaping is put into horizontal spinning machine and carry out spinning, thereby obtain the hollow rotary body wheel hub of various shape of generatrix;
(9) the mould pressing blank is put into numerically controlled lathe and machining center cut;
(10) surface treatment.
The specific embodiment
Provide the manufacturing approach most preferred embodiment of 28 inches cross-country refitted car wheel hubs below:
(1) get the raw materials ready: calculating the volume of required blank according to the wheel hub part drawing, is that the cylindrical forged hub of 420mm cuts into blank with aluminium alloy bars with diameter;
(2) clean blank: 80 ℃ of tanks blank being put into the pre-treatment medicament are removed greasy dirt and surface impurity;
(3) blank after will cleaning is put into electromagnetic induction furnace and is heated, and in heat-treatment furnace, cutting blank is preheated to 400 ℃ with 30 fens clock times--and 450 ℃ and be incubated 1 hour;
(4) rough forge: blank blocking under 800 tonnes of forging presses is become the 600mm pie;
(5) mould and die preheating: forging mold is preheated to 350 ℃ with the heating tube in the mould;
(6) on die-face, spray graphitic lubricant; There is manipulator to put into counterdie the rough forge blank that heats; To mould and blank heating, make blank temperature remain on 350 ℃ through electrothermal tube, let the blank under the high temperature semi-solid state under 1200 tonnes of forging presses, forge and press 3 times; Each forging and pressing want pressurize just to open patrix afterwards in 10 seconds, make the wheel hub preliminarily forming;
(7) take out above-mentioned forging, put into and accomplish the enlarging operation on the enlarging forcing press of the little tonnage of 3.5MN;
(8) wheel hub of preliminarily forming is put into horizontal spinning machine and carry out spinning; Rough forging is held out against on the spinning machine core with tail, drive plug and blank rotation by main shaft, spinning wheel is squeezed in material on the core of rotation from blank one side simultaneously; Utilize spray gun heating blank during spinning; The speed of mainshaft reaches 3000r/min, makes aluminium alloy wheel hub produce the pointwise continuous plastic deformation through spinning, thereby obtains the hollow rotary body wheel hub of various shape of generatrix;
(9) the mould pressing wheel hub is put into numerically controlled lathe and machining center cutting fine finishining shaping
(10) surface treatment: the wheel hub that fine finishining is shaped dusts, sprays paint through paint line and handles after detect the packing warehouse-in.
The invention solves traditional permanent mold casting blank forming method and be prone to produce shrinkage cavity, loose, casting flaw such as mechanical performance is lower, it is big to have overcome aluminium alloy wheel hub allowance, and production cost is high, the deficiency that is difficult to be used widely.And the performance of wheel hub is improved significantly.
