Description

Technical Field

[0001] The invention relates to the technical field of automobile aluminum alloy wheel hub manufacturing, in particular to a casting device for automobile aluminum alloy wheel hub manufacturing. Background Art

[0002] Aluminum alloy wheel refers to the automobile wheel made of aluminum alloy material. It is the central part of the automobile tire that supports the tire and is also an important component connecting the tire and the vehicle. During the production process, aluminum alloy wheel is usually formed by casting. The casting devices used in the manufacture of automobile aluminum alloy wheels mainly include: gravity casting device, low-pressure casting device and extrusion casting device, among which low-pressure casting device is the most widely used.

[0003] During the manufacturing process of automobile aluminum alloy wheels by the low-pressure casting device, the transfer furnace storing the molten metal is connected to the wheel mold through a riser pipe. After multiple castings, there will be alloy residues solidified due to the temperature drop in the riser pipe, so it needs to be cleaned regularly. Generally, it is necessary to wait for the transfer furnace to cool down and then clean it together with the transfer furnace. The operation is relatively cumbersome, and the riser pipe is easily corroded by the molten metal and scrapped after long-term use, which not only increases the cost, but also may cause the molten metal to increase iron and deteriorate its performance, so it needs to be replaced regularly. In the prior art, the furnace cover and the riser pipe are first removed from the transfer furnace, and then disassembled and replaced. The replacement procedure of the entire riser pipe is also relatively cumbersome.

[0011] Optionally, a first buffer sheet is fixedly connected to a surface of the connecting block close to the elastic sheet, a second buffer sheet corresponding to the position of the first buffer sheet is fixedly connected to the outside of the fixed plate, evenly distributed rubber strips are fixedly connected below the first buffer sheet and above the second buffer sheet, and second weakening grooves are provided on the outside of the first buffer sheet and the second buffer sheet.

[0012] Optionally, the disassembly assembly includes telescopic blocks that are sleeved in the cleaning tray and evenly distributed, the cleaning tray is provided with assembly grooves that are adapted to the shape of the telescopic blocks, and the telescopic blocks are fixedly connected to the connecting rod via a spring.

[0013] Optionally, baffles are provided on both sides of the telescopic block, a movable groove adapted to the shape of the baffles is opened in the assembly groove, and a clamping groove adapted to the shape of the bottom end of the liquid riser is opened at the end of the telescopic block.

[0014] Optionally, the bottom of the movable plate is symmetrically connected to a docking plate that is adapted to the size of the connecting seat, and a first channel connected to the interior of the docking plate is opened in the movable plate, a first docking hole is opened on the outside of the docking plate, and the bottom of the movable plate is fixedly connected to an air pump connected to the first channel.

[0015] Optionally, a second channel connected to the first channel is opened in the middle of the connecting rod, a third docking hole adapted to the size of the first docking hole is opened on the outside of the connecting seat, a second docking hole adapted to the size of the third docking hole is opened on the outside of the positioning block, and a third channel connected to the second docking hole is opened in the positioning block, and a connecting port connected to the third channel is opened in the connecting groove.

[0016] Compared with the prior art, the present invention has at least the following beneficial effects:

[0017] In the above scheme, by setting a cleaning component, after the position of the cleaning component is adjusted by the second servo motor, the transfer furnace and the furnace cover can be driven to move upward during the rising process of the lifting platform, so that the cleaning plate at the bottom end of the connecting rod enters the interior of the rising tube, scrapes and cleans the inner wall of the rising tube, and hangs down the residue remaining in the rising tube, thereby achieving the cleaning effect of the rising tube. The equipment existing in the original casting device is reasonably utilized to efficiently and automatically realize mechanical cleaning operations, thereby reducing the workload of the staff.

[0018] By setting up the connecting component, the air pump and the first channel, the connection relationship between the riser pipe and the furnace cover is stable and reliable, and the method of releasing the fixed state is simple and convenient. The air pump only needs to work and inflate the third channel, so that the air pressure can push the connecting block out of the connecting groove, release the connection fixed state between the connecting seat and the riser pipe, and correspondingly disconnect the connection relationship between the furnace cover and the riser pipe, so that the riser pipe can be removed from the outside of the furnace cover, which is convenient for subsequent disassembly work.

[0019] By setting up a disassembly component, after the cleaning plate passes through the bottom of the riser pipe, the air pump can work and drive the disassembly component to work, so that the telescopic block extends from the outside of the cleaning plate, and after the connecting component disconnects the fixed connection between the riser pipe and the connecting seat, during the descent of the furnace cover and the transfer furnace, the telescopic block can lift the bottom end of the riser pipe, and then separate the riser pipe and the furnace cover from each other, thereby realizing the disassembly of the riser pipe, making the disassembly operation of the riser pipe simple and convenient. The structure of the entire disassembly component is ingenious, and it cooperates with the structure of the connecting component, and cleverly uses the inflation operation of the air pump to simultaneously realize the disconnection of the connecting component and the start-up of the disassembly component.

[0020] By setting the telescopic block and the slot in the disassembly assembly, after the telescopic block is extended from the cleaning plate, during the disassembly process of the auxiliary rising tube, the bottom end of the rising tube is clamped in the slot on the telescopic block. Then, as the rising tube and the connecting seat are displaced, the first docking hole, the third docking hole and the second docking hole are also misaligned. At this time, the air pump stops working and the telescopic block is no longer affected by the air pressure. The relative position between the telescopic block and the rising tube is kept fixed by the clamping connection between the slot and the bottom of the rising tube, thereby ensuring the stability of the telescopic block during the entire disassembly process of the rising tube, reducing the working time of the air pump, and reducing the energy consumption of the entire device during the disassembly of the rising tube.

[0021] By arranging the elastic sheet and the first buffer sheet as well as the second buffer sheet and the rubber strip in the connecting assembly, the elastic sheet will be deformed at the first weakened groove when the connecting block withdraws from the connecting groove, and the first buffer sheet and the second buffer sheet will be driven to approach each other, thereby causing contact between the rubber strip on the first buffer sheet and the second buffer sheet. Subsequently, after the connecting block and the connecting groove are misaligned, the elastic sheet is subjected to the resistance of the rubber strip during the resetting process, resulting in a certain delay, thereby reducing the resistance encountered during the disassembly of the lifting tube, facilitating the disassembly operation of the lifting tube, and further improving the function of the disassembly assembly.

[0041] like Figures 1 to 10As shown, an embodiment of the present invention provides a casting device for manufacturing automobile aluminum alloy wheels, including a support frame 1, a wheel hub mold 2 is assembled on the top of the support frame 1, and a first servo motor 4 is symmetrically installed on the inner side of the support frame 1, a threaded rod 5 is fixedly connected to the driving shaft of the first servo motor 4, and a lifting platform 6 is sleeved on the outer side of the two threaded rods 5, and a transfer furnace 3 is placed on the lifting platform 6. The support frame 1 is the supporting structure of the entire device, providing a stable working environment and installation position for other equipment and structures. When the first servo motor 4 is working, it can drive the threaded rod 5 to rotate through its driving shaft, and then through the threaded connection relationship between the threaded rod 5 and the lifting platform 6, the lifting platform 6 is pushed to move up and down in the support frame 1, and then the transfer furnace 3 is driven to move up and down. The top of the transfer furnace 3 is closed by a furnace cover 18, and a liquid riser 14 is sleeved in the middle of the furnace cover 18.

[0042] A second servo motor 7 is fixedly installed on the top of the support frame 1, and the driving shaft of the second servo motor 7 extends to the inner side of the support frame 1 and is fixedly connected to a movable plate 8. A casting port adapted to the top of the riser pipe 14 is provided at the bottom of the hub mold 2. When the transfer furnace 3 follows the lifting platform 6 to move to the highest point in the support frame 1, the riser pipe 14 in the middle of the furnace cover 18 is docked with the casting port at the bottom of the hub mold 2. Two air inlet valves are also provided on the furnace cover 18. After being connected to the air pressure equipment, the interior of the transfer furnace 3 can be pressurized, and then the air pressure is used to push the molten metal in the hub mold 2 through the riser pipe 14 for casting into the hub mold 2. The principles and usage methods of the transfer furnace 3 and the furnace cover 18 are the same as those in the prior art, and will not be described in detail here. Two groups of limit plates 11 are connected, and the two groups of limit plates 11 are distributed on both sides of the movable plate 8. When the second servo motor 7 is working, it can drive the movable plate 8 to deflect through its driving shaft, and drive the structure associated with the movable plate 8 to produce corresponding displacement. The limit plates 11 are used to limit the range of movement of the movable plate 8. The two limit plates 11 are distributed near the middle and edge positions of the top plate body of the support frame 1. When the movable plate 8 is deflected to contact the limit plate 11 near the middle of the support frame 1, the end position of the movable plate 8 corresponds to the casting port position of the hub mold 2, and when the movable plate 8 is deflected to contact the limit plate 11 at the edge position of the support frame 1, the movable plate 8 and the related structures outside the movable plate 8 are all stored at the edge position of the support frame 1 to avoid obstruction to the lifting and lowering of the transfer furnace 3 in the support frame 1.

[0043] A cleaning component is used for regular cleaning of the riser pipe 14. The cleaning component is connected to the movable plate 8. The cleaning component can use the lifting platform 6 to drive the transfer furnace 3 to rise, so that the cleaning component can enter the interior of the riser pipe 14 and scrape and clean the inner wall of the riser pipe 14; a connecting component is used for assembly connection between the riser pipe 14 and the furnace cover 18. The connecting component is respectively connected to the furnace cover 18 and the riser pipe 14. The connecting component is used to maintain the connection relationship between the furnace cover 18 and the riser pipe 14, ensuring that the riser pipe 14 can stably transfer the metal stored in the transfer furnace 3 The liquid is input into the wheel hub mold 2 to form the wheel hub; a disassembly component is used for disassembling the riser pipe 14 after it is scrapped. The disassembly component is connected to the cleaning component. The disassembly component is used to assist in the separation and disassembly between the riser pipe 14 and the furnace cover 18. After the connecting component is disconnected, the bottom of the riser pipe 14 is limited, and the transfer furnace 3 follows the descending action of the lifting platform 6 to remove the riser pipe 14 from the furnace cover 18, thereby directly completing the disassembly operation of the riser pipe 14 without disassembling the furnace cover 18, and no manual operation is required by the staff, which is simple, efficient, stable and reliable.

[0044] In this embodiment, if Figures 1 to 3 As shown, the cleaning assembly includes a connecting rod 10 fixedly connected to the bottom end of the movable plate 8, and a cleaning plate 13 is fixedly connected to the bottom end of the connecting rod 10, and the length of the connecting rod 10 is greater than the length of the rising tube 14. The shape of the cleaning plate 13 is adapted to the shape of the inner wall of the rising tube 14. When it is not necessary to clean the rising tube 14, the cleaning assembly as a whole follows the movable plate 8 and is stored at the edge of the support frame 1 to avoid the existence of the cleaning assembly hindering the up and down movement of the transfer furnace 3 in the support frame 1. When it is necessary to regularly clean the inside of the rising tube 14, the second servo motor 7 works and drives the movable plate 8 to deflect through its drive shaft until The movable plate 8 drives the entire cleaning assembly to move to a position corresponding to the riser pipe 14, and then the transfer furnace 3 follows the lifting platform 6 to rise in the support frame 1, and then drives the riser pipe 14 through the furnace cover 18, so that the cleaning disc 13 is inserted from the top of the riser pipe 14, and the cleaning disc 13 enters the interior of the riser pipe 14 and contacts the inner wall of the riser pipe 14, and as the transfer furnace 3 and the lifting platform 6 rise, the outer side of the cleaning disc 13 and the inner wall of the riser pipe 14 are scraped, and the metal residue on the inner wall of the riser pipe 14 is scraped off, until the cleaning disc 13 passes through the bottom of the riser pipe 14, and the cleaning work of the riser pipe 14 is completed.

[0045] In this embodiment, if Figure 5 , Figure 8 , Fig. 9 and Fig.10As shown, the connecting assembly includes a connecting seat 19 fixedly connected to the furnace cover 18 and a positioning block 15 fixedly connected to the outside of the riser pipe 14, a connecting block 30 is symmetrically installed in the connecting seat 19, a connecting groove 37 adapted to the shape of the connecting block 30 is opened on the outside of the positioning block 15, the positioning block 15 is arranged on the outside of the riser pipe 14 to avoid affecting the structure of the inner wall of the riser pipe 14, and ensure the metal liquid conveying effect of the riser pipe 14, when the riser pipe 14 is sleeved in the middle of the furnace cover 18, the position of the positioning block 15 on the riser pipe 14 corresponds to the position of the connecting seat 19 on the furnace cover 18, the connecting block 30 in the connecting seat 19 can be embedded in the connecting groove 37 on the positioning block 15, forming a relatively fixed relationship between the furnace cover 18 and the riser pipe 14, and at the same time, the outside of the connecting seat 19 is not provided with a structure that can pull the connecting block 30, so as to avoid possible accidental touch affecting the clamping relationship between the connecting block 30 and the connecting groove 37, thereby ensuring the stability of the entire connecting assembly in the connected state. The connecting seat 19 is provided with a sliding cavity adapted to the shape of the connecting block 30, and the outer part of the connecting block 30 is symmetrically connected with an elastic sheet 31, and the end of the elastic sheet 31 is fixedly connected with a fixing plate 32. After the fixing plate 32 is in contact with the inner wall of the sliding cavity, it is fixed to the connecting seat 19 by bolts, forming a limit fixation for the connecting block 30 and the elastic sheet 31, maintaining the connection relationship between the connecting block 30 and the elastic sheet 31 and the connecting seat 19, and the middle part of the elastic sheet 31 is wavy and provided with a first weakening groove 24. The opening of the sliding cavity allows the connecting block 30 to have a space where it can move, so that the connecting block 30 can be in the sliding cavity after being subjected to external force. The sliding connection block 30 that is not affected by external forces only maintains the docking relationship between itself and the connection groove 37 under the elastic force of the elastic sheet 31. After the connection block 30 is subjected to the force toward the inside of the sliding cavity, the connection block 30 will squeeze the elastic sheet 31. The first weakened groove 24 opened on the elastic sheet 31 makes the thickness of the elastic sheet 31 at the first weakened groove 24 thinner, weaker, and easy to deform. Then, after the elastic sheet 31 is squeezed by the connection block 30, it can undergo corresponding deformation at the first weakened groove 24, cooperate with the displacement of the connection block 30, and accumulate elastic potential energy. After the external force is removed, the elastic potential energy accumulated in the elastic sheet 31 is relied on to drive the connection block 30 to reset.

[0046] A first buffer sheet 33 is fixedly connected to a surface of the connecting block 30 close to the elastic sheet 31, and a second buffer sheet 34 corresponding to the position of the first buffer sheet 33 is fixedly connected to the outside of the fixing plate 32, and uniformly distributed rubber strips 35 are fixedly connected below the first buffer sheet 33 and above the second buffer sheet 34, and second weakening grooves 36 are provided on the outside of the first buffer sheet 33 and the second buffer sheet 34. The provision of the second weakening grooves 36 makes the first buffer sheet 33 and the second buffer sheet 34 thinner and weaker in strength at the second weakening grooves 36, and more likely to deform under the action of external force. When the connecting block 30 withdraws from the connecting groove 37, the elastic sheet 31 will be deformed at the first weakening groove 24, and at the same time, the first buffer sheet 33 on the connecting block 30 will also approach the second buffer sheet 34 on the fixing plate 32, so that the first buffer sheet 33 and the rubber strips 35 on the second buffer sheet 34 are in contact, and the first buffer sheet 33 and the second buffer sheet 34 are in contact. The rubber strips 35 are arranged on the surfaces of the first buffer sheet 33 and the second buffer sheet 34 which are close to each other. After the connection block 30 is misaligned with the connection groove 37, the rubber strips 35 on the first buffer sheet 33 can contact with the rubber strips 35 on the second buffer sheet 34, and make the first buffer sheet 33 and the second buffer sheet 34 bend at the second weakened groove 36. The mutual contact between the rubber strips 35 forms an auxiliary limit for the first buffer sheet 33 and the second buffer sheet 34, so that the two will be subject to the resistance of the rubber strips 35 during the resetting process of the elastic sheet 31, so that there is a certain delay in the resetting process of the elastic sheet 31, so as to avoid the connection block 30 from being quickly reset under the action of the elastic sheet 31. After withdrawing from the connection groove 37, it will not be reset immediately and clamp the outside of the liquid riser 14, thereby reducing the resistance encountered during the disassembly process of the liquid riser 14 and facilitating the disassembly operation of the liquid riser 14.

[0047] In this embodiment, if Figures 3 to 7As shown, the disassembly assembly includes a telescopic block 22 that is sleeved in the cleaning disk 13 and evenly distributed. The cleaning disk 13 is provided with a mounting groove 21 that matches the shape of the telescopic block 22. The telescopic block 22 is fixedly connected to the connecting rod 10 via a spring 23. Baffles are provided on both sides of the telescopic block 22. The mounting groove 21 is provided with a movable groove that matches the shape of the baffle. The design of the baffle and the movable groove can limit the relative range of movement between the telescopic block 22 and the cleaning disk 13. When the telescopic block 22 is fully retracted into the cleaning disk 13, the end of the telescopic block 22 is flush with the outside of the spring 23, and cooperates with the cleaning disk 13 to form a disc-shaped structure, so that the cleaning disk 13 can normally scrape and clean the inner wall of the liquid riser 14. The end of the telescopic block 22 is provided with a spring 23 that matches the shape of the liquid riser 14. The card groove 25 with a matching shape at the bottom end is used when the riser tube 14 needs to be disassembled. After the cleaning plate 13 passes through the bottom of the riser tube 14, the telescopic block 22 in the cleaning plate 13 is pushed out. After the connecting assembly disconnects the connection between the riser tube 14 and the connecting seat 19, during the process of the furnace cover 18 and the transfer furnace 3 descending, the card groove 25 on the telescopic block 22 can contact the bottom of the riser tube 14, and then the telescopic block 22 lifts the bottom end of the riser tube 14, allowing the riser tube 14 and the furnace cover 18 to be separated from each other.

[0048] In this embodiment, if Figures 3 to 9As shown, the bottom of the movable plate 8 is symmetrically connected to a docking plate 12 that is adapted to the size of the connecting seat 19, and a first channel 16 connected to the interior of the docking plate 12 is opened in the movable plate 8, a first docking hole 17 is opened on the outside of the docking plate 12, and an air pump 9 connected to the first channel 16 is fixedly connected to the bottom of the movable plate 8.A second channel 20 connected to the first channel 16 is provided in the middle of the connecting rod 10, a third docking hole 29 matched to the size of the first docking hole 17 is provided on the outside of the connecting seat 19, a second docking hole 26 matched to the size of the third docking hole 29 is provided on the outside of the positioning block 15, and a third channel 28 connected to the second docking hole 26 is provided in the positioning block 15, and a connecting port 27 connected to the third channel 28 is provided in the connecting groove 37. When the cleaning plate 13 passes through the bottom end of the liquid riser 14, the docking plate 12 on the movable plate 8 is located on the outside of the connecting seat 19, and the first docking hole 17 on the docking plate 12 is docked with the third docking hole 29 on the outside of the connecting seat 19, and at this time, the furnace cover 18 and the liquid riser 14 are connected. The third docking hole 29 is in a connected and fixed state, one end of the third docking hole 29 away from the first docking hole 17 is docked with the second docking hole 26 on the positioning block 15, and the first channel 16, the second channel 20 and the third channel 28 are connected to each other, so that the air filled by the air pump 9 can enter the positioning block 15 through the channel formed by the first channel 16, the first docking hole 17, the third docking hole 29 and the second docking hole 26, and the air filled by the air pump 9 can also enter the cleaning disk 13 through the channel formed by the first channel 16, the second channel 20 and the assembly groove 21, so that the air filled by the air pump 9 can act on the inside of the cleaning disk 13 and the positioning block 15 at the same time, and the air entering the cleaning disk 13 can push the telescopic block 22 out of the cleaning disk 13, and the air entering the positioning block 15 is ejected through the connecting port 27, acting on the connecting block 30, pushing the connecting block 30 away from the connecting groove 37, disconnecting the fixed connection between the rising pipe 14 and the connecting seat 19, and then making the telescopic block 22 extend from the cleaning plate 13 and be able to come into contact with the bottom end of the rising pipe 14 as the transfer furnace 3 and the furnace cover 18 descend, thereby blocking the rising pipe 14, and completing the disassembly of the rising pipe 14 during the descent of the transfer furnace 3 and the furnace cover 18, so that the disassembly operation of the rising pipe 14 by the entire device can be automatically completed through the cooperation of the structure, which simplifies the disassembly steps of the rising pipe 14 and greatly reduces the workload of the staff. Secondly, the telescopic block 22 extends from the cleaning plate During the disassembly of the auxiliary rising tube 14 after extending out in 13, the bottom end of the rising tube 14 is clamped in the clamping groove 25 on the telescopic block 22. Then, as the rising tube 14 and the connecting seat 19 are displaced, misalignment occurs between the first docking hole 17, the third docking hole 29 and the second docking hole 26, and no channel can be formed. The air pump 9 also stops working, and the telescopic block 22 is no longer affected by the air pressure. The relative position between the telescopic block 22 and the rising tube 14 is kept fixed by the clamping connection between the clamping groove 25 and the bottom of the rising tube 14, so as to ensure the stability of the telescopic block 22 during the disassembly process of the entire rising tube 14, reduce the working time of the air pump 9, reduce the energy consumption of the entire device during the disassembly of the rising tube 14, and control the use cost of the device.
