Description

Technical Field

[0001] The invention relates to the technical field of die casting processing, in particular to an automatic slag bag separation device for zinc alloy die castings. Background Art

[0002] Slag bags are not usually formed integrally with the die casting. Slag bags are formed when impurities and oxides in the liquid metal gather together during cooling and usually adhere to the surface or edges of the casting. They are a byproduct of the die casting process and need to be removed in subsequent processing steps.

[0003] Announcement No. CN221362627U discloses an automatic separation device for slag bags of zinc alloy die-castings, including a frame, a material removal handle assembly, a moving mechanism, a chute, a screening assembly, a storage assembly, a first turnover box and a second turnover box. The material removal handle assembly and the moving mechanism are installed on the frame from top to bottom, a workpiece seat is arranged on the moving mechanism, and the horizontal movement of the workpiece seat is controlled by the moving mechanism; the chute is arranged on both sides of the moving mechanism, and a guide plate is installed on the workpiece seat, and the guide plate is used to guide the workpiece to fall into the chute; the screening assembly connects the chute and the storage assembly, and the first turnover box is placed at the outlet of the storage assembly for holding the workpiece; the second turnover box is placed under the screening assembly for holding the slag bag; the application adopts multiple screen tubes and support plates, and utilizes the spacing between adjacent screen tubes to make the workpiece slide down along the screen tube, and the slag bag falls from the gap between adjacent screen tubes to achieve slag bag separation, with a simple structure and low production cost.

[0004] In the die casting process, liquid metal is poured into the mold and cooled to form the die casting. Slag is formed by the accumulation of impurities and oxides during the cooling of the liquid metal. In order to ensure the quality and surface finish of the die casting, it is usually necessary to remove the slag by mechanical methods, skimmers or automated equipment.

[0005] The non-manual removal process usually consists of a robotic arm in conjunction with a removal mechanism. Through the movement of the robotic arm, the removal mechanism contacts the slag bag position. Since the slag bag is impurities and oxides and will not merge with the metal liquid, pressure is applied to the slag bag through the removal structure to break the interface between the slag bag and the die casting.

[0006] However, two problems arise from this: non-manual removal of slag bags requires a site to install a robotic arm and a removal mechanism. For a die-casting plant that has already completed the die-casting site layout, it is not convenient to arrange the robotic arm and the removal mechanism. Secondly, it is impossible to accurately obtain the status of the slag bag. Since the slag bag does not appear in a fixed position, the robotic arm needs to be inspected in subsequent processes after removing the slag bag. Summary of the invention

[0007] One of the purposes of the present invention is to provide an automatic slag bag separation device for zinc alloy die-castings, so as to solve the problem that the existing slag bag separation device occupies a large area, making it inconvenient to arrange some die-casting plants that have completed the die-casting site layout, and the slag bag state inside the die-casting can be detected during the slag bag separation process.

However, it should be understood that these practical details should not be used to limit the present invention. In other words, in some embodiments of the present invention, these practical details are not necessary. And if it is possible to implement, the features of different embodiments can be applied interchangeably.

[0070] Unless otherwise defined, all words (including technical and scientific terms) used herein have their usual meanings, which can be understood by those familiar with this field. Furthermore, the definitions of the above words in commonly used dictionaries should be interpreted as the meanings consistent with the relevant fields of the present invention in the content of this specification. Unless otherwise clearly defined, these words will not be interpreted as idealized or overly formal meanings.

[0071] See also Figure 1-Figure 14 The present invention provides an automatic separation device for slag bags of zinc alloy die castings, which is used for processing slag bags after die casting and removing slag bags attached to the surface of die castings, and has a small site requirement.

[0072] In one embodiment, the separation device comprises:

[0073] A mounting frame 1, a driving guide rail 2 is arranged inside the mounting frame 1, an extension frame 4 is arranged at the bottom of the driving guide rail 2, and the extension frame 4 moves along the setting direction of the driving guide rail 2;

[0074] A separation assembly 5 is installed inside the extension frame 4. The separation assembly 5 is retracted inside the extension frame 4 and can extend toward the middle of the extension frame 4. The separation assembly 5 moves toward the slag bag and cleans the slag bag.

[0075] The driving unit 3 is arranged inside the extension frame and is used to drive the extension frame to slide outside the driving guide rail 2;

[0076] The detection system 6 obtains the state of the die casting, determines the coordinate data between the die casting slag bag and the separation component 5, and adjusts the position of the separation component 5 according to the coordinate data between the slag bag and the separation component 5 to separate the slag bag;

[0077] The weight measuring component 7 is arranged inside the mounting frame 1, and is used to lift the die casting and obtain the weight of each lifting point, determine the center of gravity of the die casting by the weight of the lifting point of the die casting, and judge the slag bag area of ​​the die casting;

[0078] The die casting can be rotated inside the extension frame 4 to adjust the position of the die casting.

[0079] In this embodiment, the mounting frame 1 is installed on the top frame of the die-casting equipment by hoisting or fixedly installed on the outside of the die-casting equipment to ensure the stability of the mounting frame 1 and the movement accuracy of the separation component 5 when processing the slag bag of the die-casting.

[0080] The separation device is installed through the installation frame 1, and there is no need to set up an additional robot arm to grab the die-casting, and no additional installation site is required to install the separation device, so as to ensure the applicability of the separation device.

[0081] Since the center of gravity of the die-casting is constant when the structure is stable after die-casting, and the mass of the slag bag is different from that of the normal die-casting material, the appearance of the slag bag will change the center of gravity state of the die-casting. The area where the slag bag appears can be determined according to the center of gravity of the die-casting.

[0082] In one embodiment, a detection system 6 is installed on one side of a mounting frame 1, and the detection system 6 can be swung to be connected to the mounting frame 1. A lifting structure 8 is arranged between the detection system 6 and the mounting frame 1, and the lifting structure 8 controls the angle between the detection system 6 and the mounting frame 1. The detection system 6 swings to different angles corresponding to changes in the die-casting equipment. When the detection system 6 is at an angle perpendicular to the ground, it is used to detect slag bags of die-casting parts; when the detection system 6 is at an angle parallel to the ground, the die-casting equipment performs die-casting.

[0083] In this embodiment, the swingable detection system 6 can be used to control the detection system 6 according to the use status of the die-casting equipment, thereby preventing the detection system 6 from affecting the normal die-casting of the die-casting equipment.

[0084] Optionally, the detection system 6 is a visual detection system 6, which obtains a surface image of the die-casting, analyzes the position of the slag bag in the surface image of the die-casting, and locates the position of the slag bag, and separates the slag bag by controlling the separation component 5 through the slag bag positioning.

[0085] Alternatively, the detection system 6 is an ultrasonic detection system: using an ultrasonic detector, slag bags and other defects inside the die casting can be detected. Ultrasonic detection is suitable for detecting internal defects and can be combined with weight data for analysis to determine the location of the slag bags.

[0086] In one embodiment, the drive unit 3 comprises:

[0087] The driving end 31 is connected to the extension frame 4. The driving end 31 is driven by a hydraulic pump 32 to change the telescopic length of the driving end 31. The extension frame 4 is connected to the driving guide rail 2 and slides on the outside of the driving guide rail 2.

[0088] The extension frame 4 is configured as a split design, including a top frame and a bottom frame. The bottom frame can be retracted inside the top frame. The top frame is connected to the driving rail 2 and the driving end 31 .

[0089] In this embodiment, the position of the extension frame 4 is changed by the driving unit 3. When in use, corresponding to different states of the die-casting equipment, when the die-casting equipment is working for die-casting, the driving unit 3 controls the extension frame 4 to separate, which will not affect the normal die-casting production of the die-casting equipment. After the die-casting is completed and the die-casting equipment is separated, it can extend to the inside of the die-casting equipment.

[0090] Since one side of the die-casting equipment is in a fixed state and cannot move, the extension frame 4 can be stably aligned with the die-casting part.

[0091] In one embodiment, the separation assembly 5 is composed of a separation head 53 for removing the slag bag, an extension arm 52 for changing the position of the separation assembly 5, and a control unit 51 for controlling the swing position of the extension arm 52, wherein the separation head 53 includes:

[0092] The connecting end 531 is installed at one end of the extension arm 52 away from the control part 51. The connecting end 531 extends to the inside of the extension arm 52. An extrusion head 532 is arranged at one end of the connecting end 531 facing the die casting. The extrusion head 532 is retractably installed inside the connecting end 531. A cavity 536 is formed between the extrusion head 532 and the inner arm of the connecting end 531.

[0093] The driving motor 533 is installed outside the connecting end 531, and the output end of the driving motor 533 extends to the inside of the connecting end 531 and drives the extrusion head 532 to rotate;

[0094] An electric telescopic rod 534 is arranged inside the connecting end 531 , and a push plate 535 is arranged at the telescopic end of the electric telescopic rod 534 to change the shape of the cavity 536 . The cavity 536 is filled with a medium, and the push plate 535 is pushed by the electric telescopic rod 534 and the extension state of the extrusion head 532 is changed by using the medium.

[0095] In this embodiment, the extrusion head 532 is arranged to be rotatable. When cleaning the slag on the surface of the die-casting, the extrusion head 532 contacts the surface of the die-casting and then rotates to clean the slag. The telescopic length of the extrusion head 532 can correspond to different positions of the die-casting.

[0096] Among them, the electric telescopic rod 534 drives the push plate 535 to change the state of the push plate 535, so that the position of the push plate 535 changes. Since the amount of medium filled in the cavity 536 is a fixed amount, the telescopic position of the extrusion head 532 will also change after the position of the push plate 535 changes.

[0097] In order to ensure that the extrusion head 532 can rotate along with the driving motor 533 when being telescopically slidable, the output end of the driving motor 533 is configured to be non-circular.

[0098] In one embodiment, an elastic band 537 is provided on the outside of the extrusion head 532, and the inner and outer sides of the elastic band 537 extend to the extrusion head 532 and the inner side of the connecting end 531 respectively. Bristles 538 are arranged on the outer side of the elastic band 537. The elastic band 537 can rotate with the extrusion head 532, and one end of the elastic band 537 extending to the inner side of the connecting end 531 is embedded in the connecting end 531 and can rotate in a circle relative to the connecting end 531. The extrusion head 532 is extended and retracted to change the inclination angle of the elastic band 537.

[0099] In this embodiment, the bristles 538 on the outer side of the elastic band 537 are used for cleaning the slag bag after it is crushed. The bristles 538 are set to different hardnesses according to different die-cast metals.

[0100] Optionally, the bristles 538 on the outside of the elastic band 537 are steel wire bristles 538. When the extrusion head 532 rotates, the bristles 538 contact the slag bag and generate friction with the slag bag.

[0101] Among them, since the bristles 538 are installed on the outside of the elastic band 537, when in use, the change in the inclination angle of the elastic band 537 will change the angle of the bristles 538, and the inclination angle of the elastic band 537 is controlled by the extrusion head 532. Under this premise, the outward extension and retraction of the extrusion head 532 does not correspond to the position of the slag bag in the die-casting, but corresponds to the state of the slag bag. The extension and retraction state of the extrusion head 532 is adjusted according to the state of the slag bag.

[0102] In one embodiment, the separation head 53 further comprises:

[0103] A pneumatic scissors 539 is movably mounted on the outside of the connecting end 531, and the pneumatic scissors 539 can swing relative to the connecting end 531;

[0104] A spherical positioning structure 5310 is fixed to the outside of the pneumatic scissors 539. The spherical positioning structure 5310 is arranged inside the connecting end 531. A rack 5311 is arranged outside the spherical positioning structure 5310. The spherical positioning structure 5310 is meshed with an annular tooth groove 5312 arranged outside and the rack 5311.

[0105] The miniature telescopic rod 5313 is arranged on both sides of the rack 5311 to drive the rack 5311 to move;

[0106] The electromagnetic assembly 5314 is installed on the side of the pneumatic scissors 539 facing the connecting end 531, and controls the pneumatic scissors 539 to swing to different angles through electromagnetic force.

[0107] In this embodiment, the rack 5311 is engaged with the spherical positioning structure 5310, and the spherical positioning structure 5310 is driven to rotate according to the movement of the rack 5311. The tooth groove 5312 provided in the spherical positioning structure 5310 is engaged with the rack 5311, and the position of the pneumatic scissors 539 can be changed under the drive of the rack 5311.

[0108] Among them, the electromagnetic component 5314 is a control unit composed of multiple electromagnets. By changing the magnetic force of the electromagnets at different positions, the pneumatic scissors 539 are combined and controlled to swing to different inclination angles, and the slag bag on the outside of the die-casting is cleaned by starting the scissors.

[0109] The spherical positioning structure 5310 can swing relative to the rack 5311 under the electromagnetic force, and the tooth groove 5312 opened by the spherical structure is arc-shaped. Even if the spherical structure swings, the rack 5311 can stably engage with the spherical positioning structure 5310.

[0110] In one embodiment, the extension arm 52 includes:

[0111] The main arm 521 extends to the control unit 51 and is connected to the control unit 51 so that its swing angle is controlled by the control unit 51;

[0112] The auxiliary arm 522 is telescopically arranged inside the main arm 521. A guide rod 523 is arranged between the inner side of the main arm 521 and the auxiliary arm 522. The guide rod 523 is connected to the auxiliary arm 522 by magnetic attraction. The guide rod 523 is telescopically arranged to control the extension length of the auxiliary arm 522.

[0113] The tripod 524 is swingably disposed inside the main arm 521. A magnetic column 525 is disposed at one end of the tripod 524 in the extending direction of the auxiliary arm 522. The magnetic column 525 magnetically attracts the tripod 524 and shrinks inside the tripod 524.

[0114] The electromagnetic plate 526 is arranged inside the auxiliary arm 522. After the guide rod 523 pushes the auxiliary arm 522 to reach the limit position, the electromagnetic plate 526 magnetically attracts the magnetic column 525 and inserts it into the auxiliary arm 522.

[0115] The driving member 527 is disposed between the tripod 524 and the main arm 521 to control the position of the tripod 524 .

[0116] In this embodiment, the extension of the auxiliary arm 522 is divided into two stages. The first stage is to control the extension of the auxiliary arm 522 by telescoping the guide rod 523. The second stage is to continue to control the extension length of the auxiliary arm 522 through the tripod 524 after the guide rod 523 is extended to the limit position.

[0117] Optionally, the driving member 527 is a pneumatic telescopic rod. Since one end of the tripod 524 is restricted inside the main arm 521, when the middle position of the tripod 524 is pushed, the distance between the two ends of the tripod 524 increases, thereby extending the position of the auxiliary arm 522 again.

[0118] Alternatively, the driving member 527 is a combination of two electromagnetic units, and the position of the tripod 524 is controlled by magnetic separation of the electromagnetic units.

[0119] In one embodiment, the control unit 51 includes:

[0120] The arc-shaped driver 511 is installed on the inner side of the extension frame 4. A driving frame 512 is arranged on the inner side of the arc-shaped driver 511. An arc-shaped guide groove 513 is arranged on the inner side of the driving frame 512. The main arm 521 extends into the inner side of the guide groove 513. A clamping plate 514 is arranged on the inner side of the driving frame 512. The clamping plate 514 can be swung to connect with the main arm 521.

[0121] One end of the clamping plate 514 facing the driving frame 512 is driven to change position through the transmission assembly 515 , and the clamping plate 514 simultaneously drives the main arm 521 to move. Under the restriction of the guide groove 513 , the main arm 521 swings outward to extend and open.

[0122] In this embodiment, the transmission assembly 515 is a transmission motor that drives the gear to rotate to control the position of the card plate 514, so that the card plate 514 moves, and the guide groove 513 is an arc-shaped extension, and the main arm 521 extends to a fixed position inside the guide groove 513. Therefore, under the movement of the card plate 514, the main arm 521 gradually extends toward the inside of the extension frame 4.

[0123] The arc driver 511 is composed of an arc frame and gears installed inside the arc frame. The gears inside the arc frame are driven by a motor, which drives the gears to rotate. The driving frame 512 cooperates with the gears to form a transmission. The rotation of the gears changes the driving frame 512, causing the driving frame 512 to move in an arc shape.

[0124] In one embodiment, the weighing assembly 7 comprises:

[0125] The winding assembly 71 is arranged inside the mounting frame 1, and the winding assembly 71 is provided with a winding rope 72 whose extension length can be changed;

[0126] A clamp 73 is connected to one end of the winding rope 72 extending downward, and a clamp 74 is provided at the bottom of the clamp 73 which can swing to clamp the die casting, and the clamp 74 swings relative to the clamp 73;

[0127] The magnetic attraction structure 75 is disposed inside the clamping jaw 74 and clamps the die-casting by changing the swing angle of the clamping jaw 74 through magnetic attraction.

[0128] In this embodiment, the magnetic attraction structure 75 is an electromagnetic block. When in use, the mutual magnetic attraction of the electromagnetic blocks can limit the swing angle of the clamp 74, so that the clamp 74 can be used to clamp the die-casting, thereby ensuring the stability of the die-casting.

[0129] In one embodiment, the focus component further includes:

[0130] A tension sensor 76 is disposed between the clamp 73 and the reel 72 to detect the downward pulling force of the clamp 73 and determine the weight borne by the clamp 73 according to the downward pulling force;

[0131] The driving disk 77 is disposed inside the mounting frame 1 and is used to drive the winding assembly 71 to change the rotation angle;

[0132] The change in the center of gravity of the die casting is determined by the weight bearing of the clamping head 73.

[0133] In this embodiment, the tension sensor 76 can obtain the weight state of the die casting during use, determine the area of ​​the die casting where the slag bag is generated corresponding to the change in the center of gravity, detect the slag bag area, and determine the position of the slag bag.

[0134] A coordinate system is established with the detection system 6 as the center, the position of the slag bag in the coordinate system is determined, and the slag bag is separated by the separation component 5, and the separated slag bag falls.

[0135] In summary, the technical solutions disclosed in the above embodiments of the present invention have at least the following advantages:

[0136] 1. The separation device provided by the present invention is installed on the outside of the die-casting machine. Compared with the cooperation of the robot arm and the removal mechanism in the prior art, it occupies a small space and does not require additional space. It can also be supplemented and installed for the die-casting plant that has completed the die-casting site layout, thereby ensuring the applicability of the die-casting equipment and further providing a more preferred solution for the die-casting plant.

[0137] 2. The separation device for the die-casting slag bag is arranged on both sides of the die-casting machine. When the die-casting is cleaned, the position of the separation component 5 can be adjusted so that the separation component 5 can be retracted. When the separation component 5 is in the retracted state, it will not affect the normal die-casting work of the die-casting machine. When extended, it can extend to the surface of the die-casting to clean the slag bag.

[0138] 3. By adjusting the lifting of the die-casting, the center of gravity of the die-casting can be determined according to the weight of different positions of the die-casting, and the existence of slag bags and the area where the slag bags exist can be determined according to the center of gravity offset state of the die-casting, thereby realizing the detection of the die-casting and determining the state of the slag bags in the die-casting.

[0139] 4. The position of the slag bag on the surface of the die-casting is obtained through the detection system 6, and the slag bag is positioned in combination with the separation component 5. The position of the separation component 5 is adjusted according to the position of the slag bag, and the separation component 5 is controlled to move to the outside of the slag bag to clean the slag bag, thereby ensuring accurate positioning and rapid cleaning of the slag bag, and the cleaning of the slag bag is completed on the inside of the die-casting machine.

[0140] Although the present invention is disclosed in conjunction with the above embodiments, it is not intended to limit the present invention. Anyone familiar with this technology can make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention should be based on the definition of the attached claims.
