Abstract
The present invention relates to the manufacture of combined steel-aluminium wheel, especially of its blocks. The manufacture includes punching block, aluminizing block, pressure casting wheel spoke, pressure assembly of felly and wheel spoke, welding and surface treatment. The block aluminizing step of the present invention can increase the bond strength between blocks and aluminium alloy base and raise the quality of pressure cast product.
Description
The present invention relates to the job operation of a kind of steel-aluminium built-up wheel, especially the job operation of steel-aluminium built-up wheel abaculus.
Steel-aluminium built-up wheel is to be combined by steel wheel rim and aluminium matter spoke, and can not directly weld between steel and the aluminium, therefore is cast into several steel abaculus usually in advance when the die casting of aluminum alloy spoke, welds combination by steel abaculus and steel wheel rim again.
Because steel and aluminium belong to two kinds of unlike materials, after the die casting two kinds of material binding forces a little less than, mainly stretch into the abaculus endoporus by the aluminium post after solidifying and connect.Adopt this processing mode, abaculus is not happened occasionally by the phenomenon that aluminum alloy coats fully, often causes the wheel Joint strenght instability behind the assembly welding, and yields is low.
The job operation that the purpose of this invention is to provide a kind of steel-aluminium built-up wheel abaculus by changing the job operation of abaculus, solves the binding force problem of abaculus and aluminum alloy spoke, improves the Joint strenght of rim for automobile wheel and spoke, thereby increases yields.
Concrete scheme of the present invention is: comprise that abaculus punch process-die casting spoke-wheel rim and spoke press-fit-weld-surface treatment, is characterized in that: add abaculus aluminising operation between abaculus punch process operation and die casting spoke operation.
Abaculus aluminising operation is carried out as follows:
(1). at contact surface (A face) brushing one deck masking paste of abaculus and steel rim, and oven dry;
(2). abaculus is put into the penetration-assisting agent for preparing soak, soak and get final product;
(4). take out abaculus, fine aluminium or aluminium alloy solution that abaculus is put into after the fusing flood aluminising;
(5). take out abaculus, remove masking paste after cooling.
The present invention since before the die casting spoke in advance to the abaculus aluminising, therefore, can improve the binding force of steel abaculus and aluminium matter spoke greatly, eliminate abaculus and be difficult for the phenomenon that coated fully by aluminum alloy, strengthen the Joint strenght of rim for automobile wheel and spoke, the raising yields.
The present invention compared with prior art, the most significant advantage is that binding force is strong, the yields height.
The present invention is further described below in conjunction with drawings and Examples:
Fig. 1 is a flow scheme of the present invention;
Fig. 2 is steel-aluminium built-up wheel structural representation;
Fig. 3 is the front view of abaculus 2 among Fig. 2;
Fig. 4 is the left view of Fig. 3.
In Fig. 2: the 1st, steel wheel rim, the 2nd, abaculus, the 3rd, aluminium matter spoke.Wherein abaculus 2 die casting are in aluminium matter spoke 3, and the A face of abaculus 2 and steel wheel rim 1 weld.The A face position of abaculus 2 can be as seen from Figure 4.
First embodiment: the steel plate of getting 2.5mm carries out blanking, punching, bending, impression and makes abaculus.Abaculus is carried out aluminising, the masking paste that is mixed into by french talc 75g, sodium silicate 20ml, water 45ml at contact surface (A face) brushing one deck of abaculus and steel rim, the baking oven of putting into 80～120 ℃ is again dried, and takes out then, puts into by Kcl 45%, Nacl 38%, Na
3AlF
610%, soak processing in the penetration-assisting agent of Al 7% preparation, immediately change over to and carry out aluminising in the crucible furnace that the melting aluminum alloy is housed, technological condition of its dipping aluminising be under 780 ℃ of temperature 10 seconds of aluminising.Take out abaculus and put into clean charging basket, to be cooled to brushing away remaining masking paste on the abaculus with steel brush below 40 ℃, resulting aluminising thickness is 0.01mm.Before the die casting of aluminium matter spoke, with alcohol with abaculus recleaning one time in case the remaining masking paste on the abaculus is brought subsequent processing into.The abaculus of handling well is put into metal die and fix its position, the aluminium alloy solution after will melting again injects in this mould, and then with the die-cast machine pressurization, the cooling back forms the aluminum alloy spoke blank of band abaculus.Make the aluminum alloy spoke through flaw detection, heat treatment, mechanical cutting processing then.Press-fit making in advance good steel wheel rim and aluminum alloy spoke, earlier abaculus is not carried out arc-welding with the steel wheel rim and is connected in the aluminising position, carry out the ability cathode electrophoresis processing of painting again and make steel-aluminium built-up wheel.
Second embodiment: the steel plate of getting 2.5mm carries out blanking, punching, bending, impression and makes abaculus.Abaculus is carried out aluminising, the masking paste that is mixed into by french talc 75g, sodium silicate 20ml, water 45ml at contact surface (A face) brushing one deck of abaculus and steel rim, the baking oven of putting into 80～120 ℃ is again dried, and takes out then, puts into by Kcl 40%, Nacl 40%, Na
3AlF
612%, soak processing in the penetration-assisting agent of Al 8% preparation, immediately change in the crucible furnace that the fusing fine aluminium is housed and carry out aluminising, technological condition of its dipping aluminising be under 950 ℃ of temperature 9 seconds of aluminising.Duty goes out abaculus and puts into clean charging basket, and to be cooled to brushing away remaining masking paste on the abaculus with steel brush below 40 ℃, resulting aluminising thickness is 0.012mm.Before the die casting of aluminium matter spoke, with alcohol with abaculus recleaning one time in case the remaining masking paste on the abaculus is brought subsequent processing into.The abaculus of handling well is put into metal die and fix its position, the aluminium alloy solution after will melting again injects in this mould, then uses die-cast machine die casting, and the cooling back forms the aluminum alloy spoke blank of band abaculus.Make the aluminum alloy spoke through flaw detection, heat treatment, mechanical cutting processing then.Press-fit making in advance good steel wheel rim and aluminum alloy spoke, earlier abaculus is not carried out arc-welding with the steel wheel rim and is connected in the aluminising position, carry out the ability cathode electrophoresis processing of painting again and make steel-aluminium built-up wheel.
The present invention adopts the abaculus alumetizing process between abaculus punch process and die casting spoke, can not only eliminate the difficult phenomenon that is coated fully by aluminum alloy of abaculus, and carry out aluminium alloy compression casting after the aluminising of steel abaculus again, just become two kinds of die casting identical or close material of aluminium and aluminium and engaged, significantly strengthened the binding force of steel and two kinds of unlike materials of aluminium.The Joint strenght of abaculus and aluminum alloy spoke matrix is brought up to about 31 tons by original about 25 tons after testing, and the yields of spoke die casting operation also rises to 99% by original 87%.
