Description
Technical Field
[0001] The invention relates to the technical field of die-casting burr punching, and in particular to an integrated processing device for die-casting automobile burr punching. Background Art
[0002] Automotive die castings refer to automotive parts manufactured using die casting technology. After die casting, some irregular or incompletely cut metal edges, i.e. burrs or burrs, are usually formed on the edges of automotive die castings. In order to avoid the burrs affecting the quality of die castings, punching devices are required to remove the burrs of die castings.
[0003] Existing punching devices use a variety of methods to remove the burrs of die castings. For example, the Chinese invention patent with publication number CN117564717A discloses a punching device for automobile die casting burrs, including a punching base, a punching and grinding table, an adaptive positioning mechanism, a lifting and angle integrated adjustment mechanism, and a rotating mechanism. The adaptive positioning mechanism is lowered toward the top of the die casting to adaptively press and position it, and then the die casting to be polished and deburred is transferred to one side of the punching and grinding mechanism according to the side wall of the die casting to be polished and deburred. Then, according to the shape of the burrs, the power unit in the lifting and angle integrated adjustment mechanism is started to operate;
[0004] When the existing punching device punches the die casting, since the shape of the automobile die casting is not a standard square or round, its side usually has a certain curvature, so that when punching, the punching mold cannot be fully adapted to the automobile die casting, and there will be certain burrs on the die casting after the burr punching that cannot be processed. For example, the above-mentioned referenced prior art, the device only uses a punching and grinding mechanism to remove the burrs, and the die casting has an irregular shape and there are many burrs on it. Simple grinding cannot achieve efficient removal of the burrs, and the device achieves positioning by squeezing the side of the die casting. This positioning method will apply pressure to the burrs on the die casting to make it adhere to the side of the die casting, which not only fails to achieve stable positioning of the die casting, but also increases the difficulty of removing the burrs;

DETAILED DESCRIPTION
[0041] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.
[0042] Example 1: Reference Figure 1-Figure 2 , an integrated processing device for punching and trimming of automotive die castings, comprising a die casting 18 to be punched and placed on a base 1, and also comprising a punching unit and an adjusting trimming unit arranged on the base 1;
[0043] The punching unit is used to punch and remove the burrs on the die casting 18, including full punching and detail cutting, so as to achieve full removal of the burrs on the side of the die casting 18;
[0044] The trimming adjustment unit is used to adjust the position of the die casting 18 and remove the burrs in detail. The trimming adjustment unit can cooperate with the punching unit to achieve the side precision cutting of the die casting 18, and at the same time, the side of the die casting 18 is finely polished to achieve further trimming of the side of the die casting 18;
[0045] A plurality of moving wheels 30 for movement are provided at the lower part of the base 1, and the plurality of moving wheels 30 are used to drive the device to move as a whole, so as to facilitate the transfer or transportation of the overall position;
[0046] A plurality of positioning components 3 for positioning are arranged on the lower side of the base 1, and the positioning component 3 includes a fixing frame fixedly mounted on the base 1, a threaded rod is threadedly mounted on the fixing frame, and a pressure support plate is fixedly mounted on the lower part of the threaded rod. When the device performs punching of the die-casting 18 without moving, the plurality of threaded rods can be rotated to drive the plurality of pressure support plates to press against the ground, thereby completing the positioning of the base 1 and improving its placement stability.
[0047] A control box 2 is arranged on the side of the base 1, and the control box 2 is used for overall control of the operating status of the punching unit and the adjusting trimming unit and for adjusting the power supply system. A control panel 29 is arranged on the base 1, and the control panel 29 is used for targeted control of the operating status of the punching unit and the adjusting trimming unit. Through the cooperation of the control panel 29 and the control box 2, flexible and precise control of the opening and closing status of the punching unit and the adjusting trimming unit can be achieved, thereby improving the integration and automation of the punching process, and the opening and closing of the punching unit can be precisely controlled through the control panel 29, thereby improving the safety of the punching process.
[0048] Example 2: Reference Figure 1-Figure 7 The technical solution of this embodiment is different from that of the first embodiment in that the punching unit is composed of a full punching component and a detailed punching component, wherein the full punching component is used to perform a large-scale overall removal of the burrs on the die casting 18, and the detailed punching component is used to perform detailed trimming of the remaining burrs after the full punching component is punched, so as to achieve a comprehensive and thorough removal of the burrs;
[0049] The full-face stamping assembly includes a plurality of limit support rods 8 fixedly mounted on the base 1, a top plate 6 is fixedly mounted on the top of the plurality of limit support rods 8, a hydraulic cylinder 7 is fixedly mounted on the top plate 6, a lifting platform 5 is slidably mounted on the plurality of limit support rods 8, and the upper part of the lifting platform 5 is fixedly mounted on the driving end of the hydraulic cylinder 7;
[0050] When the hydraulic cylinder 7 is started, it will drive the lifting platform 5 to make it stably lift vertically, so as to facilitate the punching work of the die casting 18. The multiple limit support rods 8 play the role of limiting the lifting platform 5, which can effectively improve the lifting stability of the lifting platform 5.
[0051] A fastening screw 13 is fixedly installed in the lifting platform 5, and a punching die 11 matching the die casting 18 is threadedly installed on the fastening screw 13. The threaded fixation of the punching die 11 is completed by the fastening screw 13 to ensure the installation stability of the punching die 11.
[0052] When punching the die-casting 18, first select a suitable punching module 11 according to the shape of the die-casting 18, then install the punching module 11 on the fastening screw 13 at the bottom of the lifting platform 5, and then start the hydraulic cylinder 7 to drive the lifting platform 5 and the punching module 11 to move downward. When the punching module 11 moves downward, it will be engaged and sleeved to the outside of the die-casting 18, and the burrs on the outside of the die-casting 18 can be removed in a large area during the sleeve engagement process. The above operation can be repeated, and the punching module 11 can be driven by the hydraulic cylinder 7 to move back and forth downward to cut the burrs, thereby completing the rough cutting of the burrs on the side of the die-casting 18.
[0053] In a further embodiment, the detail punching assembly includes a hydraulic push rod 12 fixedly installed in the lifting platform 5, and a punching knife 14 is installed between the lifting platform 5 and the hydraulic push rod 12 through a sliding mechanism, and the punching knife 14 is used to perform detail punching and trimming of the burrs on the die casting 18;
[0054] The punching knife 14 is driven to move horizontally by the hydraulic push rod 12, so that the relative position between the punching knife 14 and the die casting 18 can be changed, so as to facilitate punching at different positions on the die casting 18;
[0055] The lowest point of the punching knife 14 is located below the lowest point of the punching die 11, that is, when the punching knife 14 moves downward to punch the burrs on the side of the die casting 18, the punching die 11 does not contact the die casting 18. When the punching die 11 moves downward to punch the die casting 18, the punching knife 14 is controlled by the hydraulic push rod 12 to stay away from the die casting 18, so that the punching die 11 will not be affected by the punching knife 14 during punching.
[0056] The bottom of the punching knife 14 is configured to be narrow at the bottom and wide at the top, so that it can be adapted to different shapes of the side of the die casting 18, that is, when punching the die casting 18, it will not be affected by the curvature of the side of the die casting 18, and can punch different curvatures on the side of the die casting 18;
[0057] The sliding mechanism includes a limiting slide groove 15 provided in the lifting platform 5, a clamping slide plate 31 is fixedly installed on the punching knife 14, and the clamping slide plate 31 is slidably clamped and installed in the limiting slide groove 15, and a clamping column 33 matching the clamping slide plate 31 is fixedly installed on the driving end of the hydraulic push rod 12, and the clamping column 33 and the clamping slide plate 31 are fixed by fastening bolts;
[0058] The sliding mechanism is used to enable the engaging slide plate 31 to slide horizontally in the lifting platform 5, and is used to bear and absorb the reaction force applied to the upper part when the punching knife 14 moves downward to punch the burrs, so that the vertical force applied to the punching knife 14 will not be applied to the upper part of the hydraulic push rod 12, thereby effectively protecting the hydraulic push rod 12.
[0059] Example 3: Reference Figure 1-Figure 3 as well as Figure 8-Figure 11 The difference between this embodiment and the second embodiment is that the trimming unit is composed of a positioning and adjusting component and a grinding component, wherein the positioning and adjusting component is used to position and adjust the position of the die casting 18, and the grinding component is used to grind and remove the burrs on the side of the die casting 18;
[0060] The positioning and adjusting assembly includes a processing platform 4 fixedly mounted on the base 1, a fixed cylinder 17 fixedly mounted on the processing platform 4, a placement disk 19 mounted in the fixed cylinder 17 through a steering mechanism, the steering mechanism includes a servo motor 21 fixedly mounted in the fixed cylinder 17, a rotating disk 22 rotatably mounted in the fixed cylinder 17, and the lower end of the rotating disk 22 is fixedly mounted on the driving end of the servo motor 21;
[0061] The placement plate 19 is rotatably mounted on the upper part of the fixed cylinder 17, and the die casting 18 is placed on the placement plate 19. A vacuum adsorption pump 23 is fixedly mounted on the rotating plate 22, and a vacuum suction cup 32 is arranged on the vacuum adsorption pump 23, and the side of the vacuum suction cup 32 is fixedly mounted in the placement plate 19;
[0062] After the die-casting 18 to be trimmed is placed on the placement tray 19, the position of the die-casting 18 is first adjusted according to the position of the upper punching module 11, so that the punching module 11 can be just engaged with the outside of the die-casting 18 when it moves down, and then the vacuum adsorption pump 23 is started to generate an adsorption force through the vacuum suction cup 32, so that the die-casting 18 on the placement tray 19 can be adsorbed and positioned, so that it cannot move during die-casting, and this adsorption and positioning method will not affect the side of the die-casting 18, that is, it will not affect the punching work of the burr on the side of the die-casting 18.
[0063] When the servo motor 21 is started, it drives the rotating disk 22 to rotate, and drives the die casting 18 thereon to rotate through the vacuum adsorption pump 23, the vacuum suction cup 32, and the placement disk 19, so that the horizontal position of the die casting 18 can be quickly adjusted, which is convenient for fine punching at different positions of its side, and the position adjustment of the die casting 18 will not affect its own fixing effect, that is, when adjusting the position, there is no need to change the positioning state of the die casting 18;
[0064] When the punching knife 14 moves horizontally under the control of the hydraulic push rod 12, the moving trajectory of its lower end on the placement plate 19 is projected as a straight horizontal line, and when the die-casting 18 rotates, any position on its side will eventually be on the projected horizontal line of the punching knife 14, that is, when the punching knife 14 moves downward at this time, it will perform fine punching on that part, so that when the punching knife 14 moves horizontally and the die-casting 18 rotates, it is possible to punch any position on the side of the die-casting 18 without any dead angle.
[0065] In a further embodiment, the grinding assembly includes a pressure-bearing seat 24 fixedly mounted on the processing platform 4, a lifting rod 16 is slidably mounted in the pressure-bearing seat 24, and the upper part of the lifting rod 16 is fixedly mounted on the lower part of the lifting platform 5, and two extrusion springs 25 are fixedly mounted between the lifting rod 16 and the pressure-bearing seat 24;
[0066] When the lifting platform 5 moves downward, the lifting rod 16 is squeezed to be pressed into the pressure seat 24 (when the lifting rod 16 moves downward, the two squeezing springs 25 are simultaneously compressed), and when the lifting platform 5 moves upward, the two squeezing springs 25 are not subjected to force and will automatically extend to drive the lifting rod 16 to move upward, thereby realizing automatic adjustment of the vertical position of the lifting rod 16;
[0067] A hydraulic adjustment rod 20 is fixedly mounted on the lifting rod 16, a grinding motor 26 is fixedly mounted on the driving end of the hydraulic adjustment rod 20, an adjustment spring rod 27 is fixedly mounted on the driving end of the grinding motor 26, and a grinding hemisphere 28 is fixedly mounted on the end of the adjustment spring rod 27;
[0068] When the rough cutting of the burrs on the side of the die casting 18 is completed, the hydraulic adjustment rod 20 will start to drive the grinding motor 26, the adjustment spring rod 27, and the grinding hemisphere 28 to move, so that the grinding hemisphere 28 moves to fit the side of the die casting 18. At this time, the grinding motor 26 starts to drive the grinding hemisphere 28 to rotate through the adjustment spring rod 27. When the grinding hemisphere 28 rotates, the side of the die casting 18 is polished, so that the remaining burrs on the side of the die casting 18 are polished and removed;
[0069] When the lifting platform 5 moves down to punch the die casting 18, the lifting rod 16 is driven down to drive the grinding hemisphere 28 down to automatically move away from the die casting 18. At the same time, the hydraulic adjustment rod 20 is started to drive the grinding hemisphere 28 away from the die casting 18, so as to avoid the grinding hemisphere 28 from hindering the punching of the die casting 18. When the lifting platform 5 moves up after the punching is completed, the lifting rod 16 automatically drives the grinding hemisphere 28 to move up and drives the grinding hemisphere 28 to continue to fit the side of the die casting 18 with the cooperation of the hydraulic adjustment rod 20, so that the burr grinding and trimming can continue.
[0070] The grinding hemisphere 28 is connected by adjusting the spring rod 27, which can not only exert a certain extrusion force on the grinding hemisphere 28 to make it fit more closely with the side of the die casting 18 to improve the grinding effect, but also can automatically adjust with the curvature of the side of the die casting 18, that is, when the die casting 18 rotates to the convex part of its side and contacts the grinding hemisphere 28, the adjusting spring rod 27 will automatically shrink, and when the die casting 18 rotates to the concave part of its side and contacts the grinding hemisphere 28, the adjusting spring rod 27 will automatically extend;
[0071] Therefore, the grinding hemisphere 28 can always fit closely with the side of the die-casting 18 and will not be affected by the curvature of the side of the die-casting 18. The grinding and burr removal effect is better and there will be no grinding dead angle.
[0072] A storage mechanism is provided on the processing platform 4, and the storage mechanism includes a material guide inclined plate 10 fixedly installed between the processing platform 4 and the fixed cylinder 17. A storage box 9 is installed on the processing platform 4 by means of a plurality of sets of bolts and nuts, and the storage box 9 cooperates with the material guide inclined plate 10. The burrs generated by the punching knife 14 and the punching module 11 during punching will fall onto the material guide inclined plate 10, and will automatically slide into the storage box 9 for collection under the action of gravity, thereby completing the automatic collection of the punching burrs.
[0073] The specific punching method of the punching device for the die casting 18 is as follows:
[0074] Positioning and position adjustment of the die casting 18: When punching the die casting 18, first select a suitable punching die 11 according to the shape of the die casting 18, then install the punching die 11 on the fastening screw 13 at the bottom of the lifting platform 5, and then place the die casting 18 on the placement plate 19. At the same time, adjust the position of the die casting 18 according to the position of the upper punching die 11, so that the punching die 11 can be just engaged with the outside of the die casting 18 when it moves down, and then start the vacuum adsorption pump 23 to generate adsorption force through the vacuum suction cup 32, so that the die casting 18 on the placement plate 19 can be adsorbed and positioned, so that it cannot move during die casting;
[0075] The servo motor 21 starts to drive the rotating disk 22 to rotate, and at the same time drives the die casting 18 thereon to rotate through the vacuum adsorption pump 23, the vacuum suction cup 32, and the placement plate 19, so that the horizontal position of the die casting 18 can be quickly adjusted.
[0076] Rough cutting of the burrs on the side of the die-casting 18: Start the hydraulic cylinder 7 to drive the lifting platform 5 and the punching module 11 to move downward. When the punching module 11 moves downward, it will be engaged and sleeved to the outside of the die-casting 18, so that the burrs on the outside of the die-casting 18 can be removed on a large scale during the sleeve engagement process. The above operation can be repeated, and the punching module 11 can be driven by the hydraulic cylinder 7 to move back and forth downward to cut the burrs, thereby completing the rough cutting of the burrs on the side of the die-casting 18.
[0077] Precision cutting and trimming of the remaining burrs on the side of the die casting 18: The punching knife 14 is driven to move horizontally by the hydraulic push rod 12, and the hydraulic cylinder 7 is started to drive the lifting platform 5 and the punching knife 14 to move downward. When the punching knife 14 moves downward to contact the burrs on the side of the die casting 18, the burrs on the side of the die casting 18 will be cut off. After the cutting of the previous position is completed, the die casting 18 is driven to rotate to the next position by the servo motor 21. The punching knife 14 is synchronously adjusted to the horizontal position under the action of the hydraulic push rod 12 and then continues to move downward, thereby completing the burr cutting work again;
[0078] The above operation is repeated until the die casting 18 rotates a full circle, and the overall finishing of the burrs on the side of the die casting 18 is completed.
[0079] When the rough cutting of the burrs on the side of the die casting 18 is completed, the hydraulic adjustment rod 20 will start to drive the grinding motor 26, the adjustment spring rod 27, and the grinding hemisphere 28 to move, so that the grinding hemisphere 28 moves to fit the side of the die casting 18. At this time, the grinding motor 26 starts to drive the grinding hemisphere 28 to rotate through the adjustment spring rod 27. When the grinding hemisphere 28 rotates, the side of the die casting 18 is polished;
[0080] The punching knife 14 moves up and down to punch and cut, and at the same time drives the lifting rod 16 to move up and down, and drives the grinding hemisphere 28 to automatically approach or move away from the die casting 18 through the cooperation of the hydraulic adjustment rod 20, so as to avoid the grinding hemisphere 28 blocking the cutting edge of the die casting 18;
[0081] When the die-casting 18 is rotating or the punching knife 14 is adjusting its horizontal position, the grinding motor 26 is started to drive the grinding hemisphere 28 to rotate by adjusting the spring rod 27, and the grinding work on the side of the die-casting 18 can be started, so as to grind away the remaining burrs on the side of the die-casting 18 and complete the fine finishing of the burrs on the side of the die-casting 18.
[0082] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto.
