Description

Technical Field

[0001] The invention relates to the technical field of wheel hub casting, in particular to a loading and unloading mechanism for gravity casting of an aluminum alloy wheel hub. Background Art

[0002] The manufacturing process of new energy vehicles generally includes body manufacturing, power system manufacturing, battery pack manufacturing, interior manufacturing, assembly, quality inspection and other processes. In the body manufacturing process, in order to practice the concept of low carbon and environmental protection, new energy vehicles generally use aluminum alloy wheels with recyclable materials and relatively environmentally friendly production processes. Also known as aluminum alloy rims, they are cylindrical components that are centrally assembled on the shaft and are used to support the tire's inner profile. Compared with steel car wheels, aluminum alloy wheels have the advantage of low density. The density of aluminum alloy wheels is about 1 / 3 of that of steel car wheels.

[0003] There are three methods for manufacturing aluminum alloy wheels, namely gravity casting, forging and low-pressure precision casting. Among them, the gravity casting method is to melt the aluminum ingot raw material to form an aluminum alloy solution, and then use gravity to pour the aluminum alloy solution into the mold. After forming, it is processed and polished on a lathe to complete the production.

[0004] For example, CN214114054U relates to a feeding mechanism of an aluminum ingot melting device, which includes a conveying device and a drop hopper, and the drop hopper is connected to a furnace; the height of the conveying device is greater than the drop hopper, and a transition plate is provided between the conveying device and the drop hopper, one end of the transition plate is rotatably connected to the conveying device, and the other end of the transition plate is arranged in the drop hopper; the lower end of the conveying device is provided with a driving mechanism for driving it to move up and down, and the driving mechanism is installed on a base. The feeding mechanism in this patent lacks a structure for adjusting the angle of the aluminum ingot when the aluminum ingot is put into the furnace. As is known to all, in order to avoid inhaling too much cold air during smelting to reduce heat loss and also to avoid splashing when feeding, a smaller furnace mouth diameter is generally set. When the aluminum ingot is put into the furnace, the angle between the furnace mouth and the aluminum ingot is too large, which will cause the aluminum ingot to get stuck on the furnace mouth, thereby affecting the melting of the aluminum ingot.

Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0024] In order to facilitate transportation and storage, processing and product quality, aluminum ingots are generally set in strip shape, and the existing loading and unloading device for melting aluminum ingots lacks a structure for adjusting the angle of the strip aluminum ingot. As is known to all, in order to avoid inhaling too much cold air during smelting to reduce heat loss and also to avoid splashing during feeding, a smaller furnace mouth diameter is generally set. When the strip aluminum ingot is put in, the angle between the strip aluminum ingot and the furnace mouth is too large, which will cause the strip aluminum ingot to get stuck on the furnace mouth, thereby affecting the melting of the aluminum ingot. Therefore, please refer to Figure 1 , Figure 2 , Figure 4As shown, the purpose of this embodiment is to provide a loading and unloading mechanism for gravity casting of aluminum alloy wheel hub, comprising a raw material transport component 1 and a guide adjustment component 2 arranged on the raw material transport component 1; The raw material transport assembly 1 includes a bottom support body 11 fixedly arranged on one side of the furnace and a material feeding control body 12 arranged on the top of the bottom support body 11, and the material feeding control body 12 is used to input aluminum ingot raw materials; The guide adjustment assembly 2 includes a clamping body 21 and a transmission body 22 rotatably connected to one end of the clamping body 21. The clamping body 21 is located on the feeding control body 12. The feeding control body 12 is connected to the transmission body 22 in a transmission manner. The aluminum ingot raw material is put onto the surface of the feeding control body 12. The feeding control body 12 drives the transmission body 22 to slide along the edge of the feeding control body 12, and then the clamping body 21 is driven to move along the surface of the feeding control body 12 through the transmission body 22. During the movement, the transmission body 22 drives the clamping body 21 to clamp the aluminum ingot raw material. When clamping, the aluminum ingot raw material is driven to move while adjusting the angle of the aluminum ingot raw material by virtue of the mutual extrusion between the clamping body 21 and the aluminum ingot raw material until the aluminum ingot raw material is put into the furnace mouth.

[0025] The above structure is disclosed as follows: like Figure 3 , Figure 4 As shown, the feeding control body 12 includes a feeding plate 121 arranged on the top of the bottom support body 11, and first sliding plates 122 are provided at the edge positions of both sides of the top upper surface of the feeding plate 121. The transmission body 22 is slidably connected to the first sliding plate 122. A driving body for controlling the movement of the transmission body 22 is provided on the right side of the feeding plate 121. A feeding plate 125 for guiding the aluminum ingot raw material to fall onto the surface of the feeding plate 121 is provided at the top position of the driving body on the right side of the feeding plate 121. The driving body includes a screw 123 rotatably connected to the first sliding plate 122 and a motor 124 arranged on the right side of the feeding plate 121. A transmission rod 126 is rotatably connected to the feeding plate 125, and one end of the transmission rod 126 is connected to the motor The output shaft end of the machine 124 is meshed, and the other end of the transmission rod 126 is meshed with one end of the screw 123. The other end of the screw 123 passes through the transmission body 22 and is threadedly connected to the transmission body 22. The aluminum ingot raw material is placed on the feeding plate 125, so that the aluminum ingot raw material slides downward along the inclined surface of the feeding plate 125 and falls to the surface of the feeding plate 121. The motor 124 drives the screw 123 to rotate in the first sliding plate 122 through the transmission rod 126, and then drives the transmission body 22 threadedly connected to the screw 123 to slide along the first sliding plate 122. When the transmission body 22 moves, the transmission body 22 will drive the clamping body 21 to clamp the aluminum ingot raw material on the feeding plate 121 and adjust the angle of the aluminum ingot raw material.

[0026] like Figure 3 , Figure 4 , Figure 5 , Figure 6, Figure 7 , Figure 8 As shown, the structures of the clamping body 21 and the transmission body 22 are disclosed below: The clamping body 21 includes a transverse plate 211 located on the feeding plate 121, and a pair of displacement plates 212 are arranged on the transverse plate 211. The transverse plate 211 is rotatably connected to an angle adjustment structure 213 for contacting and adjusting the angle of the aluminum ingot raw material through the arranged displacement plate 212. The angle adjustment structure 213 is rotatably connected to the transmission body 22 at one end away from the displacement plate 212. The angle adjustment structure 213 includes a movable plate 2131 rotatably connected to the displacement plate 212 at one end, and the other end of the movable plate 2131 is rotatably connected to the transmission body 22. A contact plate 2132 for contacting the aluminum ingot raw material is provided on the side of the movable plate 2131 close to the aluminum ingot raw material. A plurality of movable grooves 2133 are provided on the inner wall of the movable plate 2131. The movable grooves 2133 are "r"-shaped grooves. The second elastic connecting member 2134 is correspondingly provided with a plurality of connecting shafts. The ends of the connecting shafts are located in the movable grooves 2133. The movable plate 2131 and the movable grooves 2133 are slidably connected through the connecting shafts. Then, the contact plate 2132 is slidably connected with a second elastic connecting piece 2134 on the surface of the side away from the aluminum ingot raw material, and the second elastic connecting piece 2134 is plugged into the inner wall of the movable plate 2131. When the movable plate 2131 is driven by the transmission body 22 to move along the surface of the feed plate 121, the movable plate 2131 drives the horizontal plate 211 to move synchronously through the displacement plate 212. When the aluminum ingot raw material contacts the contact plate 2132, under the extrusion of the aluminum ingot raw material, the contact plate 2132 moves along the movable groove 2133 to overcome the elastic force of the second elastic connecting piece 2134 and first moves in a direction perpendicular to the surface of the movable plate 2131, and then moves radially in the movable plate 2131, driving the aluminum ingot raw material in contact with the surface of the contact plate 2132 to rotate, and adjusting the angle of the aluminum ingot raw material until the aluminum ingot raw material is clamped by the two movable plates 2131, and the narrow end of the aluminum ingot raw material faces the left side of the feed plate 121, that is, the furnace mouth position.

[0027] The displacement plate 212 is slidably connected to the inner wall of the horizontal plate 211, and springs are arranged on both side walls of the displacement plate 212. The two displacement plates 212 are connected by the arranged springs, and the displacement plate 212 is connected to the inner wall of the horizontal plate 211 by the arranged springs. By arranging the sliding connection and the spring connection, when clamping the aluminum ingot raw material, the movable plate 2131 can drive the displacement plate 212 to slide in the horizontal plate 211, thereby adapting to aluminum ingot raw materials of different sizes.

[0028] The transmission body 22 includes an adapter plate 221 rotatably connected to the other end of the movable plate 2131 and a translation plate 222 slidably connected to the first sliding plate 122. The end of the screw rod 123 away from the transmission rod 126 passes through the translation plate 222 and is threadedly connected to the translation plate 222. A hollow shaft 223 is inserted and matched in the translation plate 222. Second sliding plates 127 are provided on the side walls of both sides of the feeding plate 121. A second plug shaft 225 is provided at one end of the hollow shaft 223. The second plug shaft 225 is located in the plate groove on the second sliding plate 127. The plate groove is a "7"-shaped structural groove. The hollow shaft 223 and the second sliding plate 127 are slidably connected through the second plug shaft 225 and the plate groove. The other end of the hollow shaft 223 is plugged and matched with the adapter plate 221. The adapter plate 221 is provided with a first plug shaft 224 at one end close to the hollow shaft 223. The shaft 224 is located in the hollow shaft 223 and is plugged into the hollow shaft 223. One end of the hollow shaft 223 is connected to the inner wall of the hollow shaft 223 through a set spring. When the screw 123 rotates, it will drive the translation plate 222 to slide along the first sliding plate 122. During the sliding process, since one end of the hollow shaft 223 slides along the plate groove of the second sliding plate 127, the hollow shaft 223 will drive the adapter plate 221 to move inward, thereby driving the movable plate 2131 rotatably connected to the adapter plate 221 to rotate through the adapter plate 221 to clamp the aluminum ingot raw material and adjust the angle. By setting the plug-in fit and the spring connection, the adapter plate 221 can move relative to the hollow shaft 223, so that when clamping aluminum ingot raw materials of different sizes, the adapter plate 221 can drive the movable plate 2131 to contact the aluminum ingot raw material.

[0029] Further, such as Figure 2 , Figure 3 As shown, the bottom support body 11 is rotatably connected to the middle part of the feed plate 121, and the middle part of the bottom support body 11 is elastically connected with a first elastic connecting piece 111. Both ends of the first elastic connecting piece 111 are provided with limit frames 112 in contact with the bottom surface of the feed plate 121. The limit frames 112 are used to limit the feed plate 121, and the feeding plate 125 is provided with a shielding plate 128 for shielding the top of the clamping body 21. The purpose of setting the shielding plate 128 is to prevent the aluminum ingot raw material from falling along the feeding plate 125 to the outside of the movable plate 2131, and ensure that the aluminum ingot raw material can fall into the position between the two movable plates 2131 on the feed plate 121.

[0030] In summary, when the clamping body 21 and the transmission body 22 are both located on the right side of the feeding plate 121, since the overall center of gravity of the feeding plate 121 is on the right side, Fig.10 As shown, the feeding plate 121 will rotate to an inclined state with the left side higher and the right side lower. At this time, the aluminum ingot raw material slides downward through the inclined surfaces of the feeding plate 125 and the shielding plate 128 and falls onto the surface of the feeding plate 121. Fig. 9 As shown, Fig. 9The overall top view of the device after removing the shielding plate 128, the aluminum ingot raw material will slide down to the right along the surface of the feeding plate 121 until it contacts the contact plate 2132, and the movement trajectory of the aluminum ingot raw material is shown by arrow a, the motor 124 drives the screw 123 to rotate, and the screw 123 drives the translation plate 222 to slide along the first sliding plate 122 to the left side of the feeding plate 121, and the translation plate 222 will drive the hollow shaft 223 to move along the plate groove of the second sliding plate 127 during the sliding process to the left side of the feeding plate 121, driving the two adapter plates 221 The movable plate 2131 moves in the direction indicated by the arrow b, and the movable plate 2131 is driven to extrude the aluminum ingot raw material. Due to the extrusion of the aluminum ingot raw material, the contact plate 2132 moves along the movable groove 2133 to overcome the elastic force of the second elastic connecting member 2134, first in a direction perpendicular to the surface of the movable plate 2131, and then moves radially in the movable plate 2131. The movement trajectories of the two contact plates 2132 are shown as arrows c1 and c2, driving the aluminum ingot raw material in contact with the surface of the contact plate 2132 to rotate in the direction indicated by the arrow d, and adjusting the angle of the aluminum ingot raw material until it is as shown in FIG. Fig.11 As shown, at this time, the clamping body 21, the transmission body 22 and the aluminum ingot raw material move to the left position on the feed plate 121, so that the feed plate 121 rotates in the opposite direction to an inclined state with the left lower and the right higher. Under the rotation of the screw 123, the two movable plates 2131 clamp the aluminum ingot raw material, so that the narrow end of the aluminum ingot raw material is aligned with the furnace mouth, and moves in the direction of arrow e until the aluminum ingot raw material quickly slides down and detaches along the surface of the feed plate 121, and falls into the furnace mouth of the furnace, which can ensure that the aluminum ingot raw material will not get stuck on the furnace mouth, thereby avoiding affecting the melting of the aluminum ingot raw material.
