Description

Technical Field

[0001] The invention relates to the technical field of wheel hub production, in particular to aluminum alloy wheel hub production equipment which is easy to demould. Background Art

[0002] The wheel hub is a part of the tire inner profile used to support the tire. Common automobile wheel hubs include steel wheel hubs, aluminum alloy wheel hubs, etc. Among them, aluminum alloy wheel hubs are based on aluminum and added with metal materials such as manganese and magnesium. They are lighter than steel wheel hubs, so they are not only fuel-efficient, but also have good heat dissipation and high thermal conductivity, which greatly improves the braking performance of the vehicle and the life of the tire. Therefore, the use of aluminum alloy wheel hubs is becoming more and more widespread.

[0003] In the production process of aluminum alloy wheels, the chemical composition of the aluminum ingots is first analyzed. If it meets the production requirements, the aluminum ingots are melted at high temperature to form molten aluminum. The molten aluminum is then injected into the mold and forms a preliminary wheel shape during cooling. The mold is then demolded. In order to obtain an aluminum alloy wheel of qualified quality, the demolded wheel will also undergo corresponding heat treatment, machine tool processing surface treatment and other processes.

[0004] During the wheel hub casting process, parameters such as temperature, pressure and time must be strictly controlled to ensure the density and strength of the wheel hub. Otherwise, it will not only affect the quality of the wheel hub itself, but also directly reduce the demoulding efficiency of the wheel hub. Of course, demoulding is also a necessary procedure in the casting process, which mainly depends on the design of the mold itself and the synergy of the ejection structure.

The tops of the shaft seats 304 are fixedly connected to the limiting sleeves 303, and the interiors of the limiting sleeves 303 are slidably connected to the limiting rods 305. The limiting rods 305 are fixed to the second movable component 4. The second telescopic part 301 and the third telescopic part 302 are set to move synchronously. When the downward output ends of the second telescopic part 301 and the third telescopic part 302 move upward or downward, the limiting rods 305 will be driven to move up or down synchronously in the limiting sleeves 303 slidably connected thereto, thereby ensuring the movement stability and synchronization of the connected components.

[0021] like Figure 3 As shown, the output end of the first movable component 3 is fixedly connected to the second movable component 4 that moves left and right, and is used for the transportation of the wheel hub at different workstations. The second movable component 4 includes a slide rail frame 401 fixedly connected to the bottom of the second telescopic part 301 and the third telescopic part 302. A ball screw nut structure is arranged inside the slide rail frame 401. One end of the ball screw nut structure is connected to the first driving part 402 through a coupling. The first driving part 402 is fixed to one side of the slide rail frame 401. The first driving part 402 can be set as a rotating motor, and its output end passes through one side of the slide rail frame 401 and is connected to the screw.

[0022] like Figure 1 , Figure 2 As shown, a casting assembly 2 is provided on one side below the second moving assembly 4, which is used for low-pressure casting of aluminum liquid. Specifically, the casting assembly 2 includes an upper support plate 201 fixedly connected to the lower surface of the first connecting member 403, and side support plates 202 are fixedly connected to both sides of the upper support plate 201 by threads, and the side support plates 202 away from the center of the mold are fixedly connected to the first telescopic part 204, and the output end of the first telescopic part 204 passes through the side support plate 202 connected thereto and is fixedly connected to the side concave mold 203, and the side concave mold 203 is used for casting and molding the outer surface of the wheel hub, and two side concave molds 203 are provided to surround and form the outer ring shape of the wheel hub; The middle lower surface of the upper support plate 201 is fixedly connected with an upper punch 206 for internal molding of the wheel hub. A lower support plate 205 is arranged below the upper support plate 201. The lower support plate 205 is fixed on the middle table of the first frame 1. The middle of the lower support plate 205 is fixedly connected with a lower punch 207. The lower punch 207 is used for molding the lower surface of the wheel hub. Figure 2 As shown, the hub cavity is set by the side concave mold 203, the upper punch 206, and the lower punch 207 to complete the casting of the hub; Among them, the upper support plate 201 is located on the circumferential side of the upper punch 206 and is evenly penetrated by a number of ejection parts 208. The ejection parts 208 are arranged as electric ejector rods. The movable lower end of the ejection part 208 is located above the formed wheel hub. When the side die 203 moves backward, the lower end of the ejection part 208 moves downward to contact the wheel hub and exert a downward thrust on the wheel hub to assist the wheel hub in demolding, so that the aluminum alloy wheel hub can be easily demolded after casting is completed. It should be noted that the lower end of the ejection part 208 is arranged as a rubber block with a certain thickness to prevent unnecessary deformation of the wheel hub when the ejection part 208 exerts thrust.

[0023] Furthermore, a movable material storage box 7 is provided below the first frame 1 for storing aluminum liquid in a liquid state. The top pipe of the material storage box 7 is connected to the inside of the lower punch 207. When the wheel hub is cast, an inert gas is injected into the inside of the material storage box 7. Under the action of the gas pressure, the aluminum liquid inside the material storage box 7 enters the wheel hub cavity through the pipe. When the feed is sufficient, the feed is stopped, and the aluminum liquid in the wheel hub cavity is waited for to be formed under the action of cooling, thereby completing the wheel hub casting. After the wheel casting is completed, Figure 5 As shown in the upward state of the upper support plate 201 on the left side, the first moving component 3 drives the upper support plate 201 to move up to the first height H1 through the second moving component 4, and the upper support plate 201 drives the side concave mold 203, the upper punch 206 and the wheel hub to move upward synchronously, and then the second moving component 4 is operated, that is, the first driving part 402 is started, and the first connecting member 403 drives the side concave mold 203, the upper punch 206 and the wheel hub to move to the right and move to the second frame 5, thereby executing the blanking process of the wheel hub.

[0024] like Figure 3 As shown, a transmission assembly 6 is arranged on the middle table of the second frame 5, and the transmission assembly 6 includes a fourth telescopic part 601, and the fourth telescopic part 601 penetrates and is fixed on one side of the middle table of the second frame 5, and the upward output end of the fourth telescopic part 601 is fixedly connected with the second driving part 602, and the output end of the second driving part 602 is fixedly connected with a transmission plate 603 for receiving the wheel hub, and a gravity detection part 606 is installed on the upper surface of the transmission plate 603 for judging whether the wheel hub is received on the transmission plate 603; An arc-shaped slide groove 605 is provided on the middle table surface of the second frame 5, and a sliding column 604 is slidably connected inside the slide groove 605. The upper end of the sliding column 604 is fixed to the lower surface of the conveying plate 603 to support the rotation of the conveying plate 603, so that the wheel hub can rotate out of the second frame 5, which is convenient for external machines or manual material removal.

[0025] It should be supplemented that the production equipment also includes a control console arranged on one side of the first frame 1, and a control processor is arranged inside the control console to perform effective casting processes. Therefore, the control processor is connected to the first telescopic part 204, the ejection part 208, the second telescopic part 301, the third telescopic part 302, the first drive part 402, the fourth telescopic part 601, the second drive part 602, and the gravity detection part 606 by signal to perform the casting, moving, demoulding and material delivery processes of the wheel hub; The specific process is as follows, refer to Figure 1The states of the components during the casting of the hub cavity are shown in Figure 1. Then, the aluminum liquid is injected. After cooling and forming, the upper support plate 201, the side concave mold 203, the upper punch 206 and the hub are located in the second frame 5 of the first height H1 under the action of the first moving component 3 and the second moving component 4. Then, the casting component 2 is opened, that is, the side support plate 202 moves to the farthest position in the back under the action of the first telescopic part 204, ending the clamping of the hub. The conveying plate 603 waits to receive the hub above, wherein the initial pressure of the gravity detection part 606 is zero. When the hub falls and is received on the upper surface of the conveying plate 603, the gravity detection part 606 will detect the corresponding pressure value. The control processor records the pressure value data and the time difference T formed from the time when the first telescopic part 204 stops clamping the wheel hub to the time when the gravity detection part 606 can detect the pressure value. A reasonable time limit t is input in advance at the control console. When T≤t, it means that the demoulding time of the wheel hub is normal. Once T>t, it means that the demoulding time of the wheel hub exceeds the reasonable time range. In order to ensure the normal casting of the next wheel hub, the control processor transmits instructions to the ejector part 208. The lower end of the ejector part 208 extends and applies a downward thrust to the wheel hub, so that the wheel hub is supported on the conveying plate 603 below. After that, the ejector part 208 retracts to the initial position. When the hub is located on the upper surface of the transmission plate 603, the fourth telescopic portion 601 drives the transmission plate 603 and the hub to move downward to the second height H2. Figure 5 In the downward movement state of the transmission plate 603 on the right side shown in the figure, the output end of the second driving unit 602 is started and drives the transmission plate 603 to rotate 90° clockwise, and the sliding column 604 performs synchronous sliding support to complete the transmission process of the wheel hub; Then, the first moving assembly 3 and the second moving assembly 4 can drive the upper support plate 201, the undercut die 203 and the upper punch 206 to move and return to Figure 1 The next wheel hub is cast after the wheel hub cavity is in the casting state, thereby completing the casting and demoulding process in the wheel hub production process.

[0026] In order to improve the demoulding efficiency of the wheel hub, an auxiliary demoulding process that facilitates demoulding can be added to the production process of the wheel hub. Specifically, Figure 1 , Figure 6 , Figure 7 As shown, a first auxiliary component 8 is disposed on the front side of the first frame 1, and the first auxiliary component 8 includes a fifth telescopic portion 801 disposed on the front side of the first frame 1, and an output end of the fifth telescopic portion 801 is fixedly connected to a second connecting member 804, and a first auxiliary component 805 is fixedly connected to the bottom of the other end of the second connecting member 804, and a lower surface of the first auxiliary component 805 is configured to imitate the shape of the bottom of the wheel hub, so that the first auxiliary component 805 can be used to clean the lower punch 207 and assist in the demoulding process in a targeted manner from the shape; The bottom of the fifth telescopic part 801 is slidably connected to a bottom plate 802, and a third driving part 803 is installed on the bottom plate 802. The third driving part 803 can be, but is not limited to, a linear motor. The output end of the third driving part 803 is fixed to the bottom of the fifth telescopic part 801. When the output end of the third driving part 803 is started, the third driving part 803 can drive the first auxiliary part 805 to move forward and backward through the fifth telescopic part 801, so that it enters or moves out of the first frame 1. In addition, the fifth telescopic part 801 can drive the first auxiliary part 805 to move up and down to adjust the distance between the first auxiliary part 805 and the lower punch 207. Furthermore, a plurality of first through holes 807 are opened inside the first auxiliary component 805, and the tops of the plurality of first through holes 807 are all connected to first connecting pipes 806. The first connecting pipes 806 located on the second connecting component 804 are fixedly clamped on the second connecting component 804 to prevent the pipelines from being placed in a disorderly manner.

[0027] like Figure 1 , Figure 3 , Figure 8 , Fig. 9 As shown, a second auxiliary component 9 is provided at the second frame 5, and the second auxiliary component 9 includes a rotating tube 901 connected to the table of the second frame 5 by a bearing, the top of the rotating tube 901 is capped and the inside is hollow, and a second auxiliary component 906 is fixedly connected to the upper end of the rotating tube 901, and the second auxiliary component 906 is arranged in a cross-sectional shape imitating the side surface of the wheel hub, so as to facilitate cleaning of the inside of the side concave mold 203 and the outside of the upper convex mold 206 and assist in the demoulding process, and a plurality of second through holes 907 are arranged inside the second auxiliary component 906, and the inside of the rotating tube 901 is communicated with the second through holes 907; Further, a transmission mechanism is connected to the middle surface of the rotating tube 901, and the transmission mechanism includes a driven wheel 902, a transmission belt 903, a driving wheel 904, and a fourth driving part 905. The fourth driving part 905 is fixed to the bottom of the table of the second frame 5, and the output end of the fourth driving part 905 is fixedly connected to the driving wheel 904. The driving wheel 904 is connected to the driven wheel 902 through the transmission belt 903, and the driven wheel 902 is fixedly connected to the middle surface of the rotating tube 901; The bottom bearing of the rotating tube 901 is connected to the second connecting tube 908, and the two are internally communicated.

[0028] Regarding the connection method of the first connecting pipe 806 and the second connecting pipe 908, there are at least the following connection methods: Connection method 1 is as follows: Fig.12 As shown, the first connecting pipe 806 and the second connecting pipe 908 are both connected to the first pump body 910 and the second pump body 911 through pipelines, and control valves are provided on the connecting pipelines to ensure the opening and closing of the corresponding pipelines. The second pump body 911 is connected to the treated clean air, and the first pump body 910 is connected to the release agent box for spraying an appropriate amount of release agent onto the forming surface of the hub cavity to facilitate the subsequent demolding process.

[0029] Specifically, when the upper support plate 201, the undercut mold 203, the upper punch 206 and the wheel hub are moved under the action of the first moving assembly 3 and the second moving assembly 4, as shown in FIG. Fig. 9 , Fig.10 , Fig.11 As shown, first, the first auxiliary member 805 moves to a position a distance above the lower punch 207 under the action of the fifth telescopic part 801 and the third driving part 803, the control valve on the pipeline connecting the first connecting pipe 806 and the second pump body 911 is opened, and the first through hole 807 connected to the first connecting pipe 806 sprays airflow toward the lower punch 207 below, and performs a preliminary impurity removal auxiliary process to reduce the adhesion of dust particles and other impurities on the lower punch 207; Secondly, during demoulding, when the demoulding time of the wheel hub is normal, it means that there is no need to perform the auxiliary demoulding process. Then, after the conveying plate 603 rotates clockwise, the first moving assembly 3 will drive the upper supporting plate 201, the undercut mold 203, and the upper punch 206 to move down to the position of the second auxiliary member 906, wherein the undercut mold 203 and the upper punch 206 are kept Fig.10 and Fig.11 The second auxiliary member 906 is located between the side concave mold 203 and the upper punch 206, the fourth driving unit 905 is started, and its output end drives the second auxiliary member 906 and the second through hole 907 to rotate around the outer periphery of the upper punch 206, the control valve on the pipeline connecting the second connecting pipe 908 and the first pump body 910 is opened, and the surface of the hub cavity formed by the side concave mold 203 and the upper punch 206 is subjected to a preliminary impurity removal auxiliary process; The second pump body 911 can also be set as a suction pump to absorb impurities from the mold surface involved in forming the hub cavity. The specific gas ejection or suction flow rate is related to the cleanliness of the production environment and the actual compactness of the hub, thereby ensuring the effect of airflow impurity removal. On the basis of impurity removal, the purity of the casting hub surface is improved to facilitate subsequent demoulding. In addition, when the above-mentioned wheel hub demoulding time exceeds the reasonable time range, it is necessary to add a demoulding agent to the surface involved in the wheel hub cavity. Specifically, the addition requirements are as follows: when t<T≤2t, it means that the demoulding difficulty is general; when T>2t, it means that the demoulding difficulty is high. It should be noted that the ratio value here is only used to illustrate the demoulding difficulty and can affect the use of the demoulding agent; When the control processor obtains that the demoulding difficulty is normal, the first auxiliary component 805 and the second auxiliary component 906 will be used to add a total amount of q demoulding agent to the corresponding mold surface. Similarly, when the demoulding difficulty is high, a total amount of 2q demoulding agent will be added to the corresponding mold surface. During this process, the first pump body 910 is started and the second auxiliary component 906 keeps rotating. After spraying the release agent, in order to speed up the drying of the release agent, the second pump body 911 will be used again to drain the dry gas. It should be noted that a heating unit is connected to the pipeline to heat the airflow. In addition, the drainage amount of the dry gas is obviously different from the spraying or suction amount of the above impurity removal process. It can also be understood by the operating power of the first pump body 910 to prevent high-power airflow from being unfavorable for the drying and adhesion of the added release agent.

[0030] Then, after the impurities are removed or the release agent is dried, the above-mentioned position recovery process is carried out and the next hub is cast.

[0031] Usually, the demoulding agent can maintain at least c demoulding times. The demoulding after the demoulding agent is added is recorded. The actual number of times C that T≤t is maintained in the casting process is recorded with the help of the gravity detection unit 606. When the actual number is less than c times, the control console will alarm and the casting parameters will be adaptively adjusted to ensure the quality and efficiency of the wheel hub production.

[0032] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.
