Description
Technical field
The utility model relates to the technical field that aluminium alloy wheel hub is produced, and more specifically, relates to the disposable press mounting structure of a kind of aluminium alloy wheel hub bearing.
Background technology
At present aluminium alloy wheel hub bearing press mounting is to press-fit at twice, and step is more, and each step has limited and press-fit process efficiency required process time, so that reaches the bottleneck of former press-loading process.
Existing aluminium alloy wheel hub bearing press mounting technique is that in the vertical direction press-fits, and is first first to press one side, then puts on interstage bushing and another side and places bearing toward axis hole, then press another side.Concrete, former technique is formerly depressed after the bearing of face, and the bearing of putting into interstage bushing and another side toward axis hole is placed on product, above die craft equipment is depressed.
This technique needs secondary press-fitting, has increased the time press-fiting, even efficiency is still undesirable on the required shortest time of each step.Therefore, it is lower that it press-fits efficiency, causes production efficiency lower.
Summary of the invention
The utility model is at least one defect overcoming described in above-mentioned prior art, provides a kind of aluminium alloy wheel hub bearing disposable press mounting structure, can reach the disposable effect press-fiting by this press mounting structure, has improved the efficiency that press-fits production.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: the disposable press mounting structure of a kind of aluminium alloy wheel hub bearing, comprise die craft equipment, lower die tooling, be fixed on patrix bearing on die craft equipment, be fixed on the counterdie bearing on lower die tooling, also comprise interstage bushing, interstage bushing is located at upper die craft equipment and lower die tooling through product, wherein, described upper die craft equipment is provided with patrix bearing locating core, patrix bearing locating core has fluting, and the fixing patrix bearing of O type circle is housed on fluting.
Further, described patrix bearing locating core length is 25mm.Described lower die tooling is provided with counterdie bearing locating core, and its length is 25mm.
Preferably, described fluting is semicircular arc fluting.Radius r is 1mm, can effectively fix O type circle.
Further, described patrix bearing locating core and counterdie bearing locating core stretch into positioning product in interstage bushing.
In the utility model, the fluting of the patrix bearing locating core of upper die craft equipment is loaded onto O type elastic tape to fix patrix bearing, makes the not landing of patrix bearing; And upper and lower mold shaft holds locating core and adds and grow to 25mm with location interstage bushing, the frock after improvement can carry out disposablely press-fiting, and improves to reach the object that press-fits efficiency.
Compared with prior art, beneficial effect is: press mounting structure of the present utility model is loaded onto O type elastic tape to fix patrix bearing by the fluting of patrix bearing locating core, and upper and lower mold shaft hold locating core add grow to 25mm with location interstage bushing, can carry out disposablely press-fiting, improve to reach the object that press-fits efficiency, further improved the efficiency of producing.

Detailed description of the invention
Accompanying drawing, only for exemplary illustration, can not be interpreted as the restriction to this patent; For better explanation the present embodiment, some parts of accompanying drawing have omission, zoom in or out, and do not represent the size of actual product; To those skilled in the art, in accompanying drawing some known features and explanation thereof may to omit be understandable.In accompanying drawing, describe position relationship only for exemplary illustration, can not be interpreted as the restriction to this patent.
As Figure 1-3, the disposable press mounting structure of a kind of aluminium alloy wheel hub bearing, comprise die craft equipment 1, lower die tooling 2, be fixed on patrix bearing 3 on die craft equipment 1, be fixed on the counterdie bearing 4 on lower die tooling 2, also comprise interstage bushing 5, interstage bushing 5 is located at upper die craft equipment 1 and lower die tooling 2 through product 6, and wherein, upper die craft equipment 1 is provided with patrix bearing locating core 11, patrix bearing locating core 11 has fluting 12, and the fixing patrix bearing 3 of O type circle is housed on fluting 12.
In the present embodiment, patrix bearing locating core 11 length are 25mm.Lower die tooling 2 is provided with counterdie bearing locating core 21, and its length is 25mm.Preferably, fluting 12 is semicircular arc fluting.Radius r is 1mm, can effectively fix O type circle.Patrix bearing locating core 11 and counterdie bearing locating core 21 stretch into the interior positioning product of interstage bushing 5.
The present embodiment can be realized disposable press-loading process, and the method for operating of concrete press-loading process is as follows:
On upper die craft equipment 1, install mold shaft and hold 3, counterdie bearing 4 is installed on lower die tooling 2, then place successively product 6, interstage bushing 5; Start press, press down by upper die craft equipment 1, the patrix bearing 3 on two sides, counterdie bearing 4 is disposable is press-fit into place.
