Description

An automated cutting and machining device for metal die castings Technical Field

[0001] This invention relates to the field of cutting device technology, specifically to an automated cutting and machining device for metal die castings. Background Technology

[0002] Metal die castings are widely used in manufacturing fields such as automobiles and aerospace due to their advantages of high precision and high strength. During the die casting process, due to the influence of process and mold factors, castings are prone to flash, which requires subsequent processing. These excess structures directly restrict the quality of die castings. Currently, the manual processing of flash in die castings is time-consuming, labor-intensive, and inefficient.

[0003] A search revealed a Chinese patent (publication number CN118357743A) that discloses a rapid flash removal device for die-cast parts. The device includes a base, with electric push rods installed at the four corners of the outer wall of the top of the base. One end of the piston rod of each electric push rod is fixedly connected to a bracket. A motor is installed on one side of the outer wall of the bracket. One end of the output shaft of the motor is connected to a bidirectional screw via a coupling. Sliding frames are threaded onto both sides of the outer wall of the bidirectional screw. Rectangular grooves are formed on both sides of the bottom outer wall of the sliding frames, and inner rods are fixedly connected to the inner walls of these grooves. This invention ensures that the cutting plate can stably cut off the flash as it continues to move. Two complete cuts maximize the removal of protruding flash structures, avoiding the difficulty of completely cleaning flash with simple pressing structures, the presence of residual flash requiring further processing, and the phenomenon of flash bending and adhering tightly to the side of the die-cast part. This invention improves the efficiency of the flash removal device for die-cast parts.

[0004] In the aforementioned application, the cutting plate cannot cut the chamfered area of ​​the die casting when cutting the die casting, which needs to be improved. Summary of the Invention

[0005] The purpose of this invention is to provide an automated cutting and machining device for metal die castings, which solves the problem in the prior art that the cutting plate cannot cut the chamfered area of ​​the die casting with side chamfers when cutting the die casting.

[0006] To solve the above problems, the present invention employs the following technical means:

[0007] An automated cutting and machining device for metal die castings includes a worktable, a cutting assembly, and a drive mechanism for moving the cutting assembly to perform cutting. A machining table is provided on the worktable, and multiple machining openings are formed on the surface of the machining table. A support assembly is installed within each machining opening to support the die casting. The cutting assembly includes a mounting plate, with a straight cutting tool and a straight grinding plate fixedly mounted on the side wall of the mounting plate. U-shaped connectors are slidably mounted on both sides of the mounting plate, with an arc-shaped cutting tool on the lower side and an arc-shaped grinding plate on the upper side of each connector. The drive mechanism is connected to the cutting assembly.

[0008] Preferably, the axis of symmetry of the arc-shaped cutting tool forms a 45° angle with the cutting edge of the straight cutting tool, and the axis of symmetry of the arc-shaped grinding plate forms a 45° angle with the grinding surface of the straight grinding plate.

[0009] Furthermore, the arc-shaped cutting tool is composed of several stacked cutting tools with gradually changing inner diameters, and the arc-shaped grinding plate is composed of several stacked grinding plates with gradually changing inner diameters. The outer walls of the cutting tools and grinding plates are respectively fixedly connected with horizontally arranged elastic telescopic rods, and the other end of the elastic telescopic rods is fixedly connected to the connecting member.

[0010] Furthermore, the connector includes a U-shaped connecting body, with a first electric push cylinder fixedly installed on the upper and lower sides of the connecting body, and a semi-circular mounting bracket fixedly connected to the driving end of the first electric push cylinder for installing the arc-shaped cutting tool and the arc-shaped grinding plate; a fan-shaped fixing wall is fixedly installed on the outer side of the connector.

[0011] Furthermore, an adjustment module is fixedly provided on the side wall of the mounting plate. The adjustment module adopts an electric slide or an electric push cylinder to drive the connecting parts to move in opposite directions.

[0012] Furthermore, the driving mechanism includes a bracket fixedly mounted on the top of the worktable, a second motor, a rotating plate, a cross slide, a first cylinder, and a U-shaped frame. The second motor drives the rotating plate to rotate, the cross slide drives the cutting assembly to move, and the first cylinder and U-shaped frame achieve clamping and positioning of the die-cast part.

[0013] Furthermore, the support assembly includes a support frame disposed within the processing port, comprising a column and four sets of elastically extendable support arms rotatably disposed outside the column. Each support arm includes an arm body, a locking block slidably disposed within a groove, and a first elastic element.

[0014] Furthermore, the column has an internal mounting cavity, and an extrusion head is slidably disposed within the mounting cavity. The extrusion head is made of ferromagnetic material, and its sidewall is fixedly connected to a support protrusion. A second elastic element is disposed between the extrusion head and the mounting cavity.

[0015] Furthermore, an annular groove is formed on the upper surface of the lower surface of the processing table, and a magnetic ring is fixedly installed in the groove. The magnetic ring cooperates with the extrusion head in the support assembly, and assists the downward pressing action of the support arm through magnetic adsorption force during processing.

[0016] Furthermore, the device also includes a scraper, which is fixedly connected to the bottom end of the column of the support frame and moves with the rotation of the processing table. It is used to collect the chips generated during the cutting process and automatically clean them through the collection port at the bottom of the worktable, thereby improving processing efficiency.

[0017] This invention provides an automated machining device for metal die-casting parts. It has the following advantages:

[0018] By combining a straight cutting tool and a straight grinding plate with an arc-shaped cutting tool and an arc-shaped grinding plate set at a 45° angle, it can not only remove and grind the burrs on the side plane of the die-casting part, but also accurately handle the excess structure in the chamfer area of ​​the side. This solves the problem that traditional devices cannot be adapted to chamfering processing and achieves comprehensive burr removal.

[0019] The arc-shaped cutting tool and arc-shaped grinding plate are composed of multiple sets of components with gradually changing inner diameters. With the help of the elastic telescopic rod, they can automatically adapt to the chamfer size. The adjustment module can adjust the position of the connecting parts to adapt to die-cast parts of different lengths and widths, and is also compatible with the processing needs of various shapes of workpieces such as square, round, block, and shell.

[0020] In the drive mechanism, the motor, cross slide, and cylinder work together to achieve precise positioning of the cutting components and clamping of the workpiece, preventing deviation during processing. The support components, through the cooperation of the locking blocks, elastic elements, and magnetic rings, ensure stable support of the workpiece without interfering with the processing flow.

[0021] The first motor drives the machining table to rotate, enabling automatic workpiece flow. The drive mechanism can complete workpiece flipping and multi-face processing, reducing manual intervention. The scraper automatically collects cutting chips as the machining table rotates, and the support arm can automatically reset, improving processing efficiency and reducing subsequent cleaning costs.

[0040] Please refer to Figures 1-3. An automated cutting processing device for metal die castings includes a worktable 1, a cutting assembly 4, and a drive mechanism 5 for moving the cutting assembly 4 to perform cutting. The cutting assembly 4 includes a mounting plate 401. A straight cutting tool 402 is fixedly mounted on the side wall of the mounting plate 401, and the axis of symmetry of an arc-shaped cutting tool 403 forms a 45° angle with the cutting edge of the straight cutting tool 402. U-shaped connectors 405 are slidably arranged on both sides of the mounting plate 401. A semi-circular arc-shaped cutting tool 403 is arranged on the lower side of the connector 405, and one end of the inner side of the arc-shaped cutting tool 403 is located directly below the cutting edge of the straight cutting tool 402. A curved grinding plate 407 is mounted on the top of the connector 405. A straight grinding plate 406 is fixed on the side wall of the mounting plate 401. One end of the inner side of the curved grinding plate 407 is located directly below the grinding surface of the straight grinding plate 406, and the axis of symmetry of the curved grinding plate 407 forms a 45° angle with the grinding surface of the straight grinding plate 406. An adjustment module 409 for adjusting the position of the connector 405 is fixed on the side wall of the mounting plate 401. The cutting edge of the straight cutting tool 402 and the grinding surface of the straight grinding plate 406 are on the same vertical plane. When the curved cutting tool 403 and the curved grinding plate 407 are single, they can be fixed to the connector 405 respectively.

[0041] Specifically, after the die casting is completed, the die casting is placed under the cutting assembly 4. The position of the cutting assembly 4 is adjusted by the drive mechanism 5 so that the cutting edge of the straight cutting tool 402 is located on the side of the die casting. Then, the straight cutting tool 402 descends to cut the flash on the side of the die casting. The straight grinding plate 406 grinds the side of the die casting to improve the cleaning effect of the flash. By adjusting the curved cutting tool 403 and the curved grinding plate 407 to the chamfer side of the outer side of the die casting, the chamfer on the side of the die casting can be cut and ground when descending, so that the flash on the side of the die casting can be thoroughly cleaned.

[0042] In another embodiment, please refer to Figure 4. The adjustment module 409 adopts an electric slide table with a bidirectional lead screw or two sets of electric push cylinders. When the adjustment module 409 adopts an electric slide table, the two sliders of the electric slide table are fixedly connected to the two connecting parts 405 respectively. When the adjustment module 409 adopts an electric push cylinder, the driving ends of the two electric push rods are fixedly connected to the connecting parts 405 respectively. In this embodiment, an electric slide table is adopted.

[0043] Specifically, the electric slide table drives the two connecting parts 405 to move synchronously in opposite directions or in the opposite direction, thereby adjusting the position of the arc-shaped cutting tool 403 and the arc-shaped grinding plate 407 according to the size of the die-casting part, which is suitable for use with various die-casting parts of different length and width.

[0044] In another embodiment, referring to Figures 3-5, the arc-shaped grinding plate 407 is composed of several stacked grinding plates with gradually decreasing or increasing inner diameters, and the arc-shaped cutting blade 403 is composed of several stacked cutting blades with gradually decreasing or increasing inner diameters. Horizontally arranged elastic telescopic rods 408 are fixed to the outer walls of the grinding plates and cutting blades respectively. The elastic telescopic rods 408 control the movement trajectory of the cutting blades and grinding plates to be perpendicular to the cutting edge of the straight cutting blade 402 and the grinding surface of the straight grinding plate 406. At a 45° angle, the other end of the elastic telescopic rod 408 is fixedly connected to the connector 405. In this embodiment, three sets of grinding plates and cutting blades are provided respectively. The specific number can be flexibly adjusted, and this embodiment does not impose any restrictions. When there are multiple arc-shaped cutting blades 403 and arc-shaped grinding plates 407, adjacent arc-shaped cutting blades 403 or arc-shaped grinding plates 407 can be slidably connected. The arc-shaped cutting blades 403 or arc-shaped grinding plates 407 that are in contact with the connector 405 can also be slidably connected to the connector 405 to enhance stability.

[0045] Specifically, by extending the elastic telescopic rod 408 to its maximum extent, the outer walls of multiple sets of grinding plates are placed on the same vertical arc surface and remain concentrically distributed, as are the outer walls of multiple sets of cutting blades. In use, the adjustment module 409 controls the movement of the cutting blades and grinding plates to fit the chamfer of the side of the die-casting. Under the action of extrusion pressure, the cutting blades and grinding plates smaller than the chamfer size move backward, while the cutting blades and grinding plates matching the chamfer size fit the chamfer. Thus, according to the different chamfer sizes of the side of the die-casting, matching cutting blades and grinding plates can be selected to adapt to the use of die-castings with various chamfer sizes.

[0046] In another embodiment, please refer to Figures 4-5. When the sharp ends of the cutting blade and grinding plate, which are smaller than the chamfer size, press against the chamfer of the die-cast part and cause linear scratches and wear on the chamfer surface during lifting and lowering, the following solution is proposed in this example to solve the above problems: a fourth electric push cylinder 4059 is fixed on the surface of the connector 405, and a stop block 4055 is fixed on the driving end of the fourth electric push cylinder 4059. Positioning holes 4056 are opened on the surfaces of the grinding plate and the cutting blade. A horizontally arranged second electric push cylinder 4057 is fixed on the surface of the connector 405, and a vertically arranged third electric push cylinder 4058 is fixed on the driving end of the second electric push cylinder 4057.

[0047] Specifically, the second electric push cylinder 4057 drives the third electric push cylinder 4058 to move to below the positioning hole 4056. Then, the third electric push cylinder 4058 extends and inserts into the positioning hole 4056, thereby connecting a cutting tool or grinding plate smaller than the chamfer size. Subsequently, the second electric push cylinder 4057 retracts and pulls the cutting tool or grinding plate smaller than the chamfer size backward, thereby avoiding scratches caused by the edge of the cutting tool or grinding plate abutting the chamfer during movement and reducing wear. The fourth electric push cylinder 4059 extends and pushes the stop block 4055 to move to the outside of the cutting tool or grinding plate that matches the chamfer size, forming a limiting effect. This allows the cutting tool or grinding plate to stably fit the outer surface of the chamfer, avoiding elastic wobbling caused by the elastic telescopic rod 408, thereby improving the cutting or grinding effect of the chamfer.

[0048] In another embodiment, referring to Figures 4-5, the connector 405 includes a U-shaped connecting body 4051, with a first electric push cylinder 4052 fixedly mounted on the upper and lower sides of the connecting body 4051, and a semi-circular mounting bracket 4053 fixedly mounted on the driving end of the first electric push cylinder 4052. The mounting bracket 4053 is used to connect a fourth electric push cylinder 4059. A fan-shaped fixing wall 4054 is fixedly mounted on the outer side of the connector 405, and the fixing wall 4054 is used to connect an elastic telescopic rod 408 and a second electric push cylinder 4057.

[0049] Specifically, after the position of the cutting tool or grinding plate is adjusted, the first electric push cylinder 4052 moves, driving the mounting bracket 4053 to move, thereby adjusting the position of the cutting tool or grinding plate so that one end of the cutting tool or grinding plate that matches the chamfer size is on the same vertical plane as the cutting edge of the straight cutting tool 402 and the grinding surface of the straight grinding plate 406, so that the chamfer can be processed simultaneously when processing the side of the die-cast part.

[0050] In another embodiment, referring to Figure 6, a support 8 is fixedly mounted on the top of the workbench 1. The drive mechanism 5 includes a second motor 501 fixedly mounted on the top of the support 8. A rotating plate 506 is fixedly connected to the drive end of the second motor 501. Cross slides 502 are fixedly mounted on both sides of the rotating plate 506. A first cylinder 503 is fixedly mounted on the slider of the cross slide 502. A U-shaped frame 504 is fixedly connected to the drive end of the first cylinder 503. A third motor 505 is fixedly mounted on the inner side of the U-shaped frame 504. The drive end of the third motor 505 is fixedly connected to the mounting plate 401. A second cylinder 507 is fixedly mounted at the center of the rotating plate 506.

[0051] Specifically, the second motor 501 drives the rotating plate 506 to rotate, adjusting the cutting area of ​​the cutting component 4 to grind the four sides of the die-casting. The cross slide 502 drives the cutting component 4 to move, and the position of the cutting component 4 can be adjusted according to the size of the die-casting, so that the cutting component 4 can cut its sides. The cooperation of the second motor 501 and the cross slide 502 pushes the die-casting to move, which can adjust the position of the die-casting. The second cylinder 507 extends and holds the die-casting, achieving an automatic positioning and clamping effect to prevent the die-casting from shifting during cutting. The third motor 505 drives the cutting component 4 to rotate 180°, which can cut and grind from bottom to top or from top to bottom. When processing square die-castings, the cross slide 502 drives the cutting component 4 to clamp the die-casting. The first cylinder 503 moves to adjust the height of the die-casting. Finally, the third motor... The 505 motor rotates the die-casting part 90°, adjusting its original top and bottom surfaces to the front and rear sides, allowing the cutting assembly 4 to process all six sides. When processing a circular die-casting part, the above steps allow for processing of its top and bottom surfaces. When processing the side of the circular die-casting part, the third motor 505 rotates the cutting assembly 4 from horizontal to vertical, and the cross slide 502 moves the cutting assembly 4. First, the cutting edge of the straight cutting tool 402 or the curved cutting tool 403 is pressed against the side of the circular die-casting part. Then, the second motor 501 rotates the cutting assembly 4, allowing for cutting of the side and top and bottom rounded corner areas of the circular die-casting part. Finally, the curved cutting tool 403 and the curved grinding plate 407 are pressed against the side of the circular die-casting part for grinding, effectively removing the burrs. This device is suitable for processing die-casting parts of various shapes.

[0052] In another embodiment, please refer to Figures 2 and 7. The worktable 1 is I-shaped. A first motor 2 is fixed at the center of the worktable 1. A processing table 3 is fixed at the drive end of the first motor 2. A plurality of processing ports 6 are opened on the surface of the processing table 3. A support assembly 7 for supporting the die-casting part is installed inside the processing port 6. The support assembly 7 includes a cross-shaped support frame 71 located on the lower side of the U-shaped frame 504. The support frame 71 is disposed inside the processing port 6.

[0053] Specifically, by placing the die-cast part on the support frame 71, the first motor 2 drives the processing table 3 to rotate, so that the die-cast part rotates sequentially to the cutting assembly 4 for automatic cutting.

[0054] In another embodiment, please refer to Figures 8-9. The support frame 71 includes a column 711. A scraper 72 is fixedly provided at the bottom end of the column 711. One end of the scraper 72 is fixedly connected to the processing table 3. Four sets of elastically telescopic support arms 712 are rotatably provided on the outer side of the column 711. A slot 713 is provided on the inner side wall of the processing port 6. A pressing block 75 is fixedly provided at the bottom of the U-shaped frame 504. The support arm 712 includes an arm body 7121. A sliding groove is provided at one end of the arm body 7121. A locking block 7122 is slidably provided in the sliding groove. A first elastic element 7123 is fixed between the locking block 7122 and the sliding groove. A collection port is provided on the lower surface of the worktable 1. When the scraper 72 rotates with the processing table 3, it can push the debris falling during the cutting process into the collection port. A collection box is provided below the collection port to facilitate the collection of debris.

[0055] Specifically, the locking block 7122 is inserted into the slot 713 by the elastic force of the first elastic element 7123, thereby limiting the support arm 712 and keeping it horizontal. When the die-cast part is placed on the column 711, the support arm 712 supports it and prevents it from falling. When the die-cast part is in block shape, when the die-cast part is conveyed to the cutting assembly 4, the second cylinder 507 cooperates with the column 711 to press and fix the die-cast part. At this time, the second cylinder 507 cooperates with the cross slide 502 to drive the U-shaped frame 504 to descend, so that the lower pressing block 75 is inserted into the slot 713, and the locking block 7122 is removed from the slot 713. This causes the support arm 712 to rotate downward under its own weight, thereby preventing the support arm 712 from falling. The descent of the cutting assembly 4 affects the cutting of the lower area of ​​the die casting. When the die casting is a shell with an upward-concave bottom, the column 711 cannot hold the inner top wall of the die casting. The lower pressure block 75 presses down on the left and right side clamping blocks 7122, causing the left and right side support arms 712 of the die casting to rotate downward. The front and rear side support arms 712 of the die casting continue to support the shell horizontally, preventing the die casting from falling. When cutting the front and rear sides of the die casting, the cutting assembly 4 can clamp and rotate the die casting by 90°, so that the cutting assembly 4 is always on the left and right sides of the die casting for cutting. This allows for the support and processing of block and shell-shaped die castings.

[0056] In another embodiment, please refer to Figures 10-11. The column 711 has an internal mounting cavity, and an extrusion head 716 is slidably disposed in the mounting cavity. The surface of the column 711 has several through grooves. The extrusion head 716 is made of ferromagnetic material. Several support protrusions 715 passing through the through grooves are fixedly connected to the side wall of the extrusion head 716. A second elastic member 717 is fixed between the extrusion head 716 and the mounting cavity.

[0057] Specifically, when the block die-casting part is placed on the column 711, the pressure of the die-casting part presses down on the extrusion head 716, so that the extrusion head 716 descends without pushing the reset part to slide outward. After the die-casting part is removed, the extrusion head 716 slides upward by the elastic force of the second elastic element 717, so that the support protrusion 715 pushes the support arm 712 to rotate upward and keep it horizontal, so that the locking block 7122 automatically re-inserts into the locking slot 713, so that the support arm 712 returns to its original position, thereby providing support for the die-casting parts to be processed later.

[0058] In another embodiment, please refer to Figure 11. When the die-cast part is placed on the column 711, the extrusion head 716 cannot be pressed down, so that the extrusion head 716 will affect the downward rotation of the support arm 712. This example proposes the following solution to solve the above problem: the lower surface of the processing table 3 is provided with an annular groove, and a magnetic ring 74 is fixed in the groove. The extrusion head 716 is made of ferromagnetic material, and the magnetic ring 74 is located at the cutting assembly 4.

[0059] When the die-cast part is conveyed to the cutting assembly 4 for cutting, the extrusion head 716 rotates to the top of the magnetic ring 74. Through the magnetic attraction between the magnetic ring 74 and the extrusion head 716, the extrusion head 716 is lowered, thereby preventing the support arm 712 from being unable to rotate downwards when supporting the die-cast part of the housing, thus improving the applicability of the device.

[0060] The working principle is that by placing the die-casting part on the support frame 71, the first motor 2 drives the processing table 3 to rotate, so that the die-casting part rotates to the cutting component 4 for automatic cutting, thereby realizing the automated processing of metal die-casting parts.

[0061] The position of the cutting assembly 4 is adjusted by the drive mechanism 5 so that the cutting edge of the straight cutting tool 402 is located on the side of the die casting. Then, the straight cutting tool 402 descends to cut the flash on the side of the die casting, and the straight grinding plate 406 grinds the side of the die casting to improve the cleaning effect of the flash. Furthermore, by adjusting the curved cutting tool 403 and the curved grinding plate 407 to be located at the chamfer side of the outer side of the die casting, the chamfer on the side of the die casting can be cut and ground when descending, so that the flash on the side of the die casting can be thoroughly cleaned.

[0062] When the block die-casting part is placed on the column 711, the pressure of the die-casting part presses down on the extrusion head 716, so that the extrusion head 716 descends without pushing the reset part to slide outward. After the die-casting part is removed, the extrusion head 716 slides upward by the elastic force of the second elastic element 717, so that the support protrusion 715 pushes the support arm 712 to rotate upward and keep it horizontal, so that the locking block 7122 automatically re-inserts into the locking slot 713, so that the support arm 712 returns to its original position, thereby providing support for the die-casting parts to be processed later.

[0063] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
