Description

Technical Field

[0001] This invention belongs to the technical field of casting equipment, and particularly relates to a steel-aluminum alloy inlay casting device. Background Technology

[0002] Aluminum alloy inlay castings combine the lightweight properties of aluminum alloys with the high strength, pressure resistance, and wear resistance of steel. As equipment manufacturing moves towards lightweight and high mobility, inlay castings are increasingly widely used in the automotive, aerospace, and weaponry industries.

[0003] In aluminum alloy inlay casting, during mold making or shaping, the insert is pre-positioned in the corresponding location within the aluminum alloy casting mold cavity or mold cavity before pouring, according to its intended placement. The mold or mold is then closed, and molten aluminum is poured into the cavity. After cooling and solidification, the insert is tightly encased within the cast aluminum alloy casting, forming the desired workpiece. Taking the end cover of a high-speed train traction motor as an example, it is generally cast from aluminum alloy. Considering the operational strength of the internal motor and combining existing aluminum alloy inlay casting technology, the use of the aforementioned end cover equipment... Higher strength requirements were imposed: the center of the workpiece was made of steel, and aluminum alloy was cast on the outside of the steel to produce a workpiece that met the usage requirements. For the above processing, the existing processing methods mostly rely on manual or robotic arms to place the insert into the workpiece preparation mold and then perform the casting. The drawback of this method is that after the workpiece is cast, it must be removed, the insert placed in the appropriate position, the mold closed, and then the casting done again. The whole processing process is relatively cumbersome and the processing speed is limited. In particular, the repeated placement of the insert prolongs the workpiece preparation time and cannot meet the usage requirements. Summary of the Invention

[0031] To better understand the above-mentioned objectives, features, and advantages of the present invention, the present invention will be further described below in conjunction with the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0032] Numerous specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways than those described herein, and therefore the invention is not limited to the specific embodiments disclosed in the following specification.

[0033] Examples, such as Figures 1-12As shown, a steel-aluminum alloy inlay casting device includes an inlay casting equipment body, which includes a base 1 to ensure the stability of the device's position. A support frame 2 is arranged above the base 1, and a worktable 3 is arranged between the support frames 2. A lower mold closing assembly 4 is arranged above the worktable 3, which forms the lower part of the casting workpiece after mold closing and limits the inlay piece being conveyed, ensuring convenient forming during the inlay casting process. A vertical frame 5 is arranged above the rear side of the base 1, and a vertical rodless cylinder 6 is arranged on the front side of the vertical frame 5. One vertical rodless cylinder 6 is arranged on the front side of one vertical frame 5, and a vertical slider 152 slide assembly is arranged on the front side of the other vertical frame 5. When the vertical rodless cylinder 6 is in operation, the vertical slider 152 slide assembly is installed. When cylinder 6 provides driving power, it acts on the lifting frame 7. The vertical slider 152 slide bar assembly on the other side moves together with the moving end of the vertical rodless cylinder 6 to ensure the ease of vertical lifting of the lifting frame 7. The output end of the vertical rodless cylinder 6 is equipped with the lifting frame 7. The vertical lifting of the lifting frame 7 can drive the upper mold assembly 8 to move upward, so that it is separated from the formed workpiece, providing a prerequisite for workpiece demolding. The upper mold assembly 8 is set inside the lifting frame 7. After cooperating with the lower mold assembly 4, it forms the mold forming space for casting workpiece forming. A vertical slide bar 71 is set below the lifting frame 7 and passes through the worktable 3. A lifting platform 9 is set below the vertical slide bar 71. 71 is connected to the lifting frame 7 and the lifting platform 9 at both ends, and can be adjusted vertically relative to the worktable 3 to ensure the preparation of the processing work. The inner side of the lifting platform 9 is equipped with a top-loading mechanism 10, which can lift the conveyed inserts upwards to prepare the workpiece for loading, and can also push the already formed workpieces to facilitate their removal from the lower mold assembly 4, providing convenient conditions for subsequent workpiece removal. A loading assembly is provided below the worktable 3 to receive the loaded inserts and cooperates with the top-loading mechanism 10 to load the inserts. An insert support assembly 12 is used to temporarily store a workpiece to be processed. On the one hand, it can support the inserts in advance to ensure the smooth progress of casting work. On the other hand, it can shorten the feeding process during feeding and ensure the continuity of insert feeding. The insert placement component is used to receive a batch of insert workpieces to be fed and to make the workpieces cooperate with the first feeding mechanism 14 to realize the single output of the workpieces. The first feeding mechanism 14 and the second feeding mechanism 15 are used to realize the first feeding and second feeding actions of the insert workpieces respectively, and to transport the workpieces far away from the processing area to the top feeding mechanism 10. It is linked with the operation of the lifting mechanism, which not only improves the functionality of the device and equipment, but also ensures the continuity of workpiece feeding and ensures the work process.

[0034] In the above process: the established ejector mechanism 10 can, on the one hand, lift the conveyed inserts upwards to prepare for workpiece loading, and on the other hand, it can push the already formed workpieces so that they can be easily removed from the lower mold assembly 4, providing convenient conditions for subsequent workpiece removal. The established insert support assembly 12 temporarily stores a workpiece to be processed, which can, on the one hand, support the inserts to ensure the smooth progress of casting, and on the other hand, shorten the loading process and ensure the continuity of insert loading. The established insert placement assembly is used to receive a batch of insert workpieces to be loaded and to cooperate with the first feeding mechanism 14 to achieve single-point guidance of the workpieces. The device utilizes the first feeding mechanism 14 and the second feeding mechanism 15 to perform primary and secondary feeding actions on the insert workpieces, respectively, conveying the workpieces far from the processing area towards the top feeding mechanism 10. This is coordinated with the operation of the lifting mechanism, improving the functionality of the device and ensuring the continuity of workpiece feeding, thus guaranteeing the work process. The device is rationally designed, simple in structure, and easy to process. It can replace manual labor or robotic arms for convenient loading of insert workpieces. On the one hand, it improves the functionality of the device, reducing the complexity of the processing process; on the other hand, it integrates workpiece feeding and workpiece ejection functions, optimizing the processing process, saving time and labor costs, and meeting usage requirements.

[0035] To form the casting mold for the workpiece, the lower mold assembly 4 includes four sets of drive mechanisms 41 arranged in a cross shape. Each drive mechanism 41 includes a mounting base 411, a drive cylinder 412 on one side of the mounting base 411, a drive plate 413 at the output end of the drive cylinder 412, a limit rod 414 at the corner of the drive plate 413, and a connecting plate 415 on the other side of the limit rod 414. At the moving ends of the four sets of drive mechanisms 41, fan-shaped front mold 42, rear mold 43, left mold 44, and right mold 45 are respectively positioned. Under the drive of the drive mechanisms 41, the front mold 42, rear mold 43, left mold 44, and right mold 45 move closer or further apart to achieve mold closing or mold opening, respectively. After mold closing, the main body of the workpiece to be cast is formed. Figure 5As shown: The components placed above the front mold 42, rear mold 43, left mold 44, and right mold 45 constitute the casting workpiece body. After the workpiece is demolded and ejected, it can be removed using equipment such as a robotic arm in the factory and transported to a centralized workpiece placement area, ensuring the continuity of processing. Specifically, the front mold 42, rear mold 43, left mold 44, and right mold 45, which are designed as separate units, can be closed by the drive mechanism 41. The lower part of each mold limits the insertion parts that are transported up. For workpieces of the same batch and with the same processing specifications, each... After the molds are closed, they can maintain a consistent position. Mold separation can be performed only when it is necessary to clean the inside of the molds. That is, the drive cylinder 412 is extended and acts on the drive plate 413. The drive plate 413 pulls the limit rod 414 and the connecting plate 415 outward, thereby separating the molds. After the molds are closed, the upper mold assembly 8 limits and fits the corners of each mold to ensure the tightness of the fit between the molds. Of course, the sealing treatment between the molds is a conventional technology in the prior art, which can be effectively known by those skilled in the art, and will not be described in detail here.

[0036] To ensure the integrity of the workpiece molding, the upper mold assembly 8 includes a support plate 81 positioned above the lifting frame 7. A lifting drive cylinder 82 is positioned above the support plate 81, and a lifting plate 83 is positioned at the output end of the lifting drive cylinder 82. A connecting rod 84 is positioned below the lifting plate 83, and an upper mold 85 is positioned below the connecting rod 84, fitting onto the lower mold assembly 4 after mold closing. A positioning tube 86 is positioned below the upper mold 85, and a feed pipe 87 is positioned on one side of the upper mold 85. Specifically, the upper mold assembly 8 can, on the one hand, utilize the vertical movement of the lifting frame 7 to move the upper mold assembly 8 away from the lower mold assembly 4, providing sufficient space for the ejection of the molded workpiece; on the other hand, it can utilize the lifting drive cylinder... The extension and retraction of cylinder 82 drives the upper mold 85 to move vertically. Its mold closing process can be closely matched with the various molds of the lower mold assembly 4 to ensure the forming quality of the workpiece. Its demolding process separates the upper mold 85 from the upper end face of the formed workpiece, providing convenient conditions for the subsequent ejection of the workpiece. As for the established feed pipe 87, this component is used to receive the aluminum liquid scooped by the robot arm. The filtrate enters through the feed pipe 87 and flows into the upper mold assembly 8 and the lower mold assembly 4 to realize the forming of the processed workpiece. As for the established positioning pipe 86, its lower end is closely matched with the inner side of the insert to be embedded to realize the closure of the lower mold assembly 4 and ensure the forming preparation of the workpiece.

[0037] To facilitate the lifting of the insert workpiece, the lifting mechanism 10 includes a connecting frame 101 connected to the lifting platform 9. Lifting blocks 102 are provided at the inner ends of multiple connecting frames 101. A fixed plate 103 is provided above the lifting blocks 102, and a semi-circular lifting rod 104 is provided above the fixed plate 103. A vertical rod 105 is provided on the lifting blocks 102 located outside the fixed plate 103, penetrating the material loading assembly and the worktable 3. Through holes 106 are provided in the rear mold 43, left mold 44, and right mold 45 corresponding to the vertical rod 105, so that the vertical rod 105 can lift the prepared workpiece. Specifically, the lifting blocks 102 are connected to the lifting platform 9 by the connecting frame 101. As the lifting platform 9 rises with the lifting frame 7, it also lifts the workpiece. The block 102 rises, which in turn acts on the push rod 104. The push rod 104 then abuts against the lower end face of the workpiece conveyed by the second feeding mechanism 15, and pushes the workpiece upward as it moves upward until it moves into the insert support assembly 12. The insert, which is placed in the insert support assembly 12 first, is pushed upward by the subsequent insert and placed in the lower mold assembly 4, providing convenient conditions for its subsequent embedding with the cast aluminum alloy. Of course, the vertical rod 105 is raised together with the lifting block 102 and extends into the geometric center of the mold in the lower mold assembly 4, pushing the already formed workpiece so that the workpiece can be easily removed from the lower mold assembly 4, and providing convenient conditions for the subsequent removal of the workpiece, thus meeting the usage requirements.

[0038] To ensure convenient loading of insert workpieces, the loading assembly includes a longitudinal support frame 11 connected to the worktable 3, which provides a convenient installation position for various devices that automatically load insert workpieces. An insert support assembly 12 is installed above the longitudinal support frame 11, corresponding to the ejector mechanism 10. This assembly is used to temporarily store a workpiece to be processed. On the one hand, it supports the preceding insert, ensuring smooth casting operations; on the other hand, it shortens the loading process during loading, ensuring the continuity of insert loading. Simultaneously, it can also eject the formed workpiece when the next insert arrives, thus playing a certain ejector role. An L-shaped upright plate 111 is installed above the rear side of the longitudinal support frame 11, providing support for the placement position of the insert workpiece and also providing space for the workpiece to fall. Furthermore, it can limit the movement direction of the workpiece to prevent it from deviating. An insert placement assembly is installed above the upright plate 111 for supporting… The device receives a batch of insert workpieces to be loaded and coordinates the workpieces with the first feeding mechanism 14 to achieve single loading of the workpieces. The insert placement assembly is equipped with a first feeding mechanism 14 for pushing the inserts forward. The first feeding mechanism 14 conveys the workpieces falling from the insert placement assembly in one operation. A second feeding mechanism 15 is provided below the longitudinal support frame 11 to convey the workpieces conveyed by the first feeding mechanism 14 to the top feeding mechanism 10. In other words, the workpieces fed in one operation are conveyed to the top feeding mechanism 10 by the second feeding mechanism 15, so that the workpieces can complete the subsequent pushing loading operation. A linkage mechanism 16 connected to the lifting platform 9 is provided on the outside of the second feeding mechanism 15. The linkage mechanism 16 receives the driving power of the lifting block 102 that moves upward with the lifting platform 9 and acts on the second feeding mechanism 15 to ensure the continuity and convenience of the workpiece loading operation.

[0039] To ensure single-piece feeding of insert workpieces and prevent workpiece accumulation that could disrupt the work process, the insert placement assembly includes a rotatable and openable feeding mechanism 13. A feeding cylinder 131 is positioned above and outside the feeding mechanism 13, containing a batch of insert workpieces ready for casting. The feeding mechanism 13 can perform a single-piece feeding action on each workpiece in the feeding cylinder 131. Specifically, the feeding mechanism 13 includes a positioning disk 132 with a concave cross-section, mounted on a vertical plate 111. A fixing ring disk 133 is located within the positioning disk 132. A through groove, adapted to the inner side of the fixing ring disk 133, is formed at the geometric center of the positioning disk 132. A positioning post 134 is positioned on the fixing ring disk 133. The outer side of the positioning post 134... A fan-shaped plate 135 is provided. A ring-shifting frame 136 is located within a positioning plate 132 outside the fixed ring plate 133. A keyway 1361 is formed within the ring-shifting frame 136. A limit post 137 is provided within the positioning plate 132 corresponding to the keyway 1361. A connecting key 138 is located on the upper inner side of the ring-shifting frame 136, with one end rotatably connected to the outer side of the fan-shaped plate 135. A notch 1321 is formed on the outer side of the positioning plate 132. A connecting strip 1362 is located on the outer side of the ring-shifting frame 136 at the notch 1321. An arc-shaped gear disk 139 is located on the outer side of the connecting strip 1362. Specifically, after the first feeding mechanism 14 pushes an insert to the unloading hole 112, the first feeding mechanism 14 moves backward. The upper drive rack 143 drives the mating rack 145 to move rearward, meshing with the gear disk 139. The gear disk 139 receives the driving power and transmits it to the ring transfer frame 136 via the connecting bar 1362. The ring transfer frame 136 rotates relative to the positioning disk 132, causing the connecting key 138 to rotate as well. The rotation of the connecting key 138 pulls the sector plates 135 to rotate relative to the positioning post 134. Each sector plate 135 opens in a flower-like pattern until the through groove of the positioning disk 132 connects with the inner side of the fixed ring disk 133. At this time, the workpiece placed in the discharge cylinder 131 falls through this point. After the workpiece falls, the first feeding mechanism 14 operates, conveying the workpiece towards the discharge hole 112. The rack 145 moves forward and acts on the gear disk 139. At this time, the direction of the driving force is reversed, which can drive the sector plate 135 from the open state to the closed state. Of course, considering that the upper and lower workpieces are close to each other, the upper end face of the sector plate 135 near the inner end face of the positioning disk 132 is designed to be inclined outward from its geometric center. In this way, when the sector plate 135 resets, it can slide to support the lower end face of the upper workpiece upward until it is closed, preventing the workpiece from falling and piling up. Of course, the above design mainly considers the linkage effect between the equipment. The operation of the unloading mechanism 13, that is, its opening and closing state, can also be driven and controlled by a cylinder. This method can also realize the unloading of a single workpiece.The inclusion of cylinders does not affect the level of automation of the equipment; in fact, their free control and drive enable more precise control. Both methods can be freely set up and selectively used according to different application requirements.

[0040] To facilitate the loading of insert workpieces, the first feeding mechanism 14 includes a feeding plate 141 positioned between two adjacent vertical plates 111, receiving inserts falling from the unloading mechanism 13. One side of the feeding plate 141 is arc-shaped and adapted to the outer periphery of the insert to push it towards the unloading hole 112. A square slot is provided in one vertical plate 111. A linkage rod 142 is provided on the outer side of the feeding plate 141. An upper drive rack 143 is provided on one side of the linkage rod 142. An upper limit seat 144 is provided on the outer side of the upper drive rack 143. A gear disk 144 is provided above the upper drive rack 143. The mating rack 145, which is engaged with the gear disk 139, moves together with the upper drive rack 143. To ensure smooth movement of the mating rack 145, a slotted hole is provided in the upper limit seat 144 to allow the L-shaped mating rack 145 to move relative to the upper limit seat 144. When the first feeding mechanism 14 moves forward, the mating rack 145 meshes with the gear disk 139, causing the unloading mechanism 13 to close and preventing the workpiece from falling. When the first feeding mechanism 14 moves backward, the mating rack 145 moves backward and meshes with the gear disk 139, providing power to the unloading mechanism 13. The opening and closing drive force allows the insert to fall from the feeding cylinder 131 onto the longitudinal support frame 11 via the feeding mechanism 13, and the workpiece is placed on one side of the feeding plate 141, waiting for the workpiece to complete the feeding process. A feeding hole 112 is provided in the longitudinal support frame 11 at the end of the vertical plate 111. Specifically, the lower drive rack 157 receives the drive force and acts on the rotating gear 158. The rotation of the rotating gear 158 meshes with the upper drive rack 143, driving the upper drive rack 143 to slide relative to the upper limit seat 144. The sliding of the upper drive rack 143 will drive the linkage rod 142 to move relative to the vertical plate 111. The sliding mechanism simultaneously drives the feeding plate 141 to push the workpiece toward the unloading hole 112 until the workpiece is placed into the end of the pusher plate 154, which moves in the backward direction. After the workpiece falls onto the pusher plate 154, the second feeding mechanism 15 operates, which pushes the workpiece toward the top feeding mechanism 10. The first feeding mechanism 14 pushes the workpiece falling from the unloading mechanism 13 toward the unloading hole 112. The workpiece falls from the unloading hole 112 onto the second feeding mechanism 15, waiting for the workpiece loading process. The above design makes the device operate relatively smoothly and improves the practicality of the equipment.

[0041] To ensure timely feeding of the outer insert workpiece towards the feeding mechanism 10, the second feeding mechanism 15 includes a longitudinal slide bar 151 located below the longitudinal support frame 11. A slider 152 is mounted on the slide bar 151, and a movable plate 153 is mounted on the slider 152. A pusher plate 154 is positioned above one side of the movable plate 153. A limit cover 155 is located below the longitudinal support frame 11 outside the pusher plate 154. A lower limit seat 156 is located outside the limit cover 155, and a lower drive rack 157 is located inside the lower limit seat 156. One side of the lower drive rack 157 is connected to the slider 152 and slides relative to the lower limit seat 156, approaching the limit cover 152. A rotating gear 158 is installed in the longitudinal support frame 11 at one end of 55, and meshes with the upper drive rack 143 and the lower drive rack 157 respectively. When the slider 152 and the moving plate 153 move relative to the longitudinal slide bar 151 with the driving power delivered by the linkage mechanism 16, the lower drive rack 157 will slide along with the slider 152 due to the setting of the lower limit seat 156. At the same time, the rearward movement of the lower drive rack 157 will mesh with the rotating gear 158. After receiving the driving power, the rotating gear 158 will apply the driving power to the upper drive rack 143, so that the driving power is applied to the first feeding mechanism 14, so that the first feeding mechanism 14 and the second feeding mechanism 153 can interact. The feeding mechanism 15 operates synchronously, and their movement directions remain opposite, i.e., they move towards each other or away from each other. A receiving hole 1551 is provided in the limiting cover 155 corresponding to the position of the push rod 104 in the feeding mechanism 10. A pushing plate 154 corresponding to the receiving hole 1551 has a pushing hole 1541. A loading hole 113 is provided in the longitudinal support frame 11 corresponding to the feeding mechanism 10. Specifically, the limiting cover 155 has a concave cross-section, and the width of the push plate 154 is smaller than the width of the workpiece. Thus, when the push plate 154 moves backward, the push rod 104 moves upward, facilitating the pushing of the workpiece. It should be further noted that the push plate... The height of the push plate 154 is the same as the height of the limit cover 155. The end of the push plate 154 has a slot to receive the workpiece at the unloading hole 112. The upper end face of the push rod 104 in the top material mechanism 10 abuts against the lower end face of the insert exposed on both sides of the push plate 154 through the top material hole 1541. When the top material mechanism 10 rises, it can quickly push the lower end face of the workpiece and push the workpiece upward. At this time, the push plate 154 is pushed to the rear through the linkage mechanism 16, and the top material mechanism 10 pushes the insert through the loading hole 113 to be transported into the insert support assembly 12, completing the loading of a workpiece and allowing the workpiece to wait for subsequent loading or processing work to meet different usage requirements.

[0042] To ensure the continuity of insert feeding and provide a prerequisite for casting operations, the insert support assembly 12 includes a conical limiting cylinder 121 positioned above the longitudinal support frame 11. A T-shaped placement groove 1211 is formed at the top of the limiting cylinder 121. A telescopic rod 122 is installed within the placement groove 1211. A wedge-shaped limiting block 123 is located at the end of the telescopic rod 122. A telescopic spring 124 is sleeved on one side of the telescopic rod 122, and one side of the spring abuts against the placement groove 1211. Specifically, the insert, fed by the second feeding mechanism 15, is placed above the top feeding mechanism 10. The lifting frame 7 is raised, which in turn drives the top feeding mechanism 10 to rise. In particular, the top rod 104 pushes the workpiece upward. When the upper end of the insert passes the limiting block 123, due to the inclined design of the lower inner surface of the limiting block 123, the continuous upward movement of the insert will press against the limiting block 123, causing it to move inward relative to the limiting cylinder 121. The telescopic rod 122 and the limiting block 123 move outward together, and the insert is placed on the... The telescopic spring 124 in the slot 1211 is compressed. When the lower end of the insert just disengages from the limiting block 123, the compressed telescopic spring 124 extends and drives the limiting block 123 to reset until the upper end face of the limiting block 123 is placed on the lower end face of the insert, limiting its position. The insert that is sent into the insert support assembly 12 abuts against the lower end face of the previous insert, which is the insert that is ready to be used for inlay casting. That is to say, the insert placed in the insert support assembly 12 abuts against the lower end face of the previous insert. The support serves two purposes: firstly, it ensures that the inserts are fed into the lower mold assembly 4 to await casting; secondly, it supports the inserts. The positioning tube 86 in the upper mold assembly 8 is matched and engaged with the inserts to ensure smooth casting. Thus, the inserts will begin processing first, while the inserts in the insert support assembly 12 await the next workpiece to be pushed forward for processing. This significantly reduces workpiece loading time, ensures continuous production, and meets usage requirements.

[0043] To improve the interoperability between devices and ensure consistent operation, the linkage mechanism 16 includes an extension plate 161 located below the lifting platform 9. A connecting rod 162 is mounted on the outer side of the extension plate 161 and connected to the outer side of the moving plate 153 of the second feeding mechanism 15. Both ends of the connecting rod 162 are rotatably connected. Specifically, regardless of whether the second feeding mechanism 15 is in a state of completed feeding or waiting for feeding, the connecting rod 162 is inclined. The lifting block 102 rises with the lifting frame 7, and the driving force generated during its ascent acts on the connecting rod 162. The lower end of the connecting rod 162 receives the driving force and acts on the moving plate 153, causing the moving plate 153 to move along the slide bar 151 with the slider 152. The upper part slides upward, thus providing the driving force for the second feeding mechanism 15 to slide backward. When the front end of the pusher plate 154 in the second feeding mechanism 15 moves to the position of the unloading hole 112, it receives the workpiece conveyed by the first feeding mechanism 14 and waits for the next conveying. After the molded workpiece is taken out, the upper mold assembly 8 first descends with the lifting frame 7. At the same time, the lifting block 102 also descends and pulls the connecting rod 162 downward, thereby driving the second feeding mechanism 15 to convey the next workpiece to the position of the top material mechanism 10 until the insert is placed above the top material mechanism 10, that is, at the position of the loading hole 113, waiting for the next insert workpiece to be lifted. This ensures the continuity of the feeding process of the device equipment. In addition, the establishment of the linkage mechanism 16 improves the coordination effect between the various devices and meets the usage requirements.
