The development of the times, vehicles as a transportation means, has become an indispensable part of human society, and provides great convenience for the life of people whether transporting goods or people.
The hub is one of important parts of the vehicle, the center of the hub is connected with the axle, the hub not only plays a role in supporting the whole vehicle, but also has great influence on the driving performance of the vehicle, and the hub with good quality can improve the stability of the vehicle in the driving process and is not easy to damage.
At present, manufacturers for producing hubs usually adopt a casting mode to produce the hubs, but compared with the prior art, the shapes of the hubs become more and more complex, the manufacturers for manufacturing the hubs need to arrange more complex structures such as inner grooves on the hubs according to the requirements of consumers, and the traditional die casting mode has the requirement of draft, so that the hubs with the structures such as the inner grooves cannot be cast.
After the wheel hub needs to be cast, structures such as an inner groove are machined through a numerical control lathe, and therefore the machining process of the whole wheel hub is complex, the manufacturing time is long, and the qualified rate is low.
To this end, some embodiments of the invention propose a method for casting a hub, illustrated in particular in figure 1 of the accompanying drawings.
Referring to fig. 1, in some embodiments, in a hub casting process, a mold 100 including a bottom mold 110, a top mold 130 and a plurality of side molds 120 is used, the top mold 130 is located above the bottom mold 110, the plurality of side molds 120 is connected to a periphery of the bottom mold 110 and surrounds the top mold 130, and a cavity 140 is defined between the top mold 130, the side molds 120 and the bottom mold 110, and the hub casting method includes the following steps: firstly, prefabricating a matched sand core 150 according to the shape of a hub; secondly, placing the sand core 150 on the bottom die 110; step three, mounting the top die 130 and the side die 120 on the bottom die 110; step four, entering a pressurizing stage, so that the aluminum liquid enters the cavity 140 from the pouring gate 111 in the bottom die 110 under the action of pressure; step five, entering a pressure maintaining stage, and fully cooling and solidifying the aluminum liquid injected into the cavity 140 in the pressure maintaining process to obtain a hub casting; step six, after the hub casting is formed, pressure is relieved, the top die 130 and the side die 120 are opened, and the hub casting and the sand core 150 are taken out of the bottom die 110 together; and step seven, putting the hub casting into water, cooling, and melting and dispersing the sand core 150 in the water.
It should be noted that the mold 100 is prefabricated in accordance with the shape of the hub to be cast, and if the hub to be cast has a complicated structure such as an inner groove, the prefabricated mold 100 can only cast the general shape of the hub to be cast in consideration of the draft required for casting in the prefabrication process of the mold 100, and the sand core 150 is used in cooperation with the casting of the hub.
It should be noted that the plurality of side forms 120 have the same shape, which can reduce the number of processes for manufacturing the side forms 120.
It should be noted that the shapes of the plurality of side forms 120 may also be different, and are not described herein again.
The connection of the plurality of side forms 120 to the periphery of the bottom mold 110 means that the plurality of side forms 120 are closely attached to the side surface of the bottom mold 110, or the plurality of side forms 120 are placed on the bottom mold 110 and closely attached to the top surface of the bottom mold 110.
It should be noted that, according to practical situations, the shape of the hub in the first step may be any shape, such as a hub shape with an inner groove, and is not limited in particular herein.
In the first step, after the shape of the hub is determined, and the portion of the hub, which cannot be directly cast by the mold 100, is determined in accordance with the shape of the mold 100, so that the sand core 150 is formed into the same shape as the portion.
It should be noted that, in the second step, the position where the sand core 150 is placed is determined according to the shape of the hub, and the sand core 150 matching with the hub is placed at the correct position, so that after the sand core 150 is placed, the cavity 140 defined between the top mold 130, the side mold 120 and the bottom mold 110 is the same as the shape of the hub, thereby successfully casting the required hub.
When the top mold 130 and the side molds 120 are mounted on the bottom mold 110, gaps between the top mold 130 and the plurality of side molds 120 and gaps between the bottom mold 110 and the plurality of side molds 120 should be as small as possible, so that smooth progress of the casting process is ensured and raw materials can be saved.
When the wheel hub is cast, the mold 100 is fixed above a sealed high-temperature molten aluminum bath, and dry compressed air is introduced into the sealed molten aluminum bath, so that molten aluminum enters the cavity 140 in the mold 100 under gas pressure.
It should be noted that, according to actual conditions, the mold 100 may also be fixed at other places, and at this time, the pressurized aluminum liquid may enter the cavity 140 through other manners, for example, the pressurized aluminum liquid may enter the cavity 140 of the mold 100 through a pipeline.
It should be noted that the pouring gate 111 is gradually reduced from bottom to top, so that the speed of the aluminum liquid in the pouring gate 111 is gradually increased.
It will be appreciated that the sand core 150 cannot stick to the mold 100, so when the hub casting is removed in step six, the sand core 150 is removed with the hub casting and placed in the water in step seven.
In some embodiments, in the fourth step, the pressurizing phase includes a first pressurizing phase and a second pressurizing phase, the first pressurizing phase lasts for 8 to 11 seconds, the aluminum liquid is pressurized by 0.22bar in the first pressurizing phase, after the first pressurizing phase is finished, the second pressurizing phase is entered, the second pressurizing phase lasts for 9 to 12 seconds, and the pressure of the aluminum liquid is 0.32bar in the second pressurizing phase.
It can be understood that, in the first pressurizing stage, the molten aluminum is pressurized at 0.22bar and slowly flows into the cavity 140 to fill most of the area of the cavity 140, and in the second pressurizing stage, the molten aluminum is pressurized at 0.32bar, the flow rate of the molten aluminum is increased, and the molten aluminum begins to fill the area of the cavity 140 which is not filled in the first pressurizing stage, and by arranging the two different pressurizing stages, the quality of the cast hub casting can be improved.
It should be noted that, in the first pressurization stage, the pressure applied to the aluminum liquid may be other, as long as the molding of the hub casting is not damaged.
In the second pressurizing stage, the pressure applied to the molten aluminum may be other pressure, as long as the molding of the hub casting is not damaged.
In some embodiments, in step five, the pressure in the cavity 140 is maintained at 0.9bar, and the pressure maintaining stage is continued until the molten aluminum is sufficiently cooled and solidified.
It can be understood that in the process of cooling and solidifying the aluminum liquid, the pressure is continuously applied to the cavity 140, so that the hub casting can keep a better material density after being molded, and a better performance can be obtained.
In the fifth step, the pressure maintained in the cavity 140 may be other pressure as long as the molding of the hub casting is not damaged.
In some embodiments, the bottom mold 110 is provided with a positioning step, and the sand core 150 is positioned on the bottom mold 110 by the positioning step.
It should be noted that the position of the positioning step on the bottom mold 110 should match the shape of the hub to be cast, so that after the sand core 150 is positioned on the bottom mold 110 by the positioning step, the cavity 140 defined between the top mold 130, the side mold 120 and the bottom mold 110 is the same as the shape of the hub, thereby smoothly casting the desired hub.
The positioning step is an integral member with the bottom mold 110, and after the shape of the hub to be cast is determined, the bottom mold 110 and the positioning step are integrally molded.
The positioning step may not be an integral member with the bottom mold 110, and the positioning step may be fixedly connected to the bottom mold 110 by welding or the like.
It should be noted that, according to actual situations, the shape of the positioning step may be various shapes, and is not specifically limited herein.
In some embodiments, sand core 150 is made of a mixture of quartz sand and resin.
In some embodiments, in step four, a filter screen is disposed in the pouring port 111 of the bottom mold 110 before the molten aluminum is poured into the cavity 140.
It can be understood that impurities exist in the molten aluminum, and if the impurities are not filtered, the impurities can affect the quality of the cast hub casting.
The filter screen is made of a high-temperature resistant material, and the filter screen does not react with aluminum.
In some embodiments, the wheel hub casting obtained in the seventh step is subjected to shakeout cleaning and shot blasting.
It can be understood that the wheel hub casting processed by the shakeout cleaning and the shot blasting can remove burrs and the like on the surface of the wheel hub casting, and finally processed into the wheel hub which can be really applied to the vehicle through a series of process flows of air tightness detection, paint spraying and the like.
In some embodiments, the bottom mold 110, the top mold 130, and the side mold 120 are blown by air guns to remove impurities before step two.
It can be understood that the mold 100 may have some dust and other impurities left before being used, and at this time, the quality of the cast hub casting may be affected when the mold 100 is used to cast the hub, and after the air gun is used to perform the blowing operation on the bottom mold 110, the top mold 130 and the side mold 120, the impurities may be removed, so as to improve the quality of the hub casting.
The embodiments of the present invention are described in detail above with reference to the accompanying drawings, and finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention, and not to limit the same; while the invention has been described in detail and with reference to the foregoing embodiments, it will be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some or all of the technical features may be equivalently replaced; and the modifications or the substitutions do not make the essence of the corresponding technical solutions depart from the scope of the technical solutions of the embodiments of the present invention.
