Example 1

[0074] The embodiment of the present invention provides an automated shaping device for metal castings, such as Figure 1-Figure 5 As shown, it includes a frame 1 and a punching unit installed on the frame 1. Moving wheels can be installed at the bottom of the frame 1 to facilitate the movement of the equipment. The shaping equipment also includes:

[0075] A workbench 2 is provided on the frame 1, one end of the workbench 2 being rotatably connected to the frame 1 via a rotating shaft 201. The punching unit is located above the workbench 2 and is used to punch the casting on the workbench 2.

[0076] A deburring unit provided on one side of the workbench 2 is used to deburr the casting;

[0077] The transfer unit installed on the frame 1 is used to transfer the stamped casting on the workbench 2 to the deburring unit. The first baffle can be fixed on the front and rear sides of the workbench 2 to prevent the casting from falling from the side of the workbench 2;

[0078] The transfer unit includes two drive disks 3 provided on the front and rear sides of the workbench 2. A first motor 18 for driving the drive disks 3 to rotate is fixedly mounted on the frame 1. The first motor 18 is a stepping motor. A pin 9 is eccentrically fixedly connected between the two drive disks 3. A through slot for the pin 9 to penetrate and move is opened on the workbench 2 along its length direction.

[0079] When working, Figure 1As shown, the workbench 2 is kept horizontal, the casting is placed on the workbench 2, and then the casting is stamped by the stamping unit. After the stamping is completed, the first motor 18 drives the drive disk 3 to rotate, the drive disk 3 drives the pin 9 to move, and the pin 9 drives the workbench 2 to tilt toward the deburring unit. The stamped casting on the workbench 2 slides to the deburring unit without manual transfer, which reduces the workload and work intensity of the workers and improves work efficiency.

[0080] In a specific implementation, both driving disks 3 are equipped with clamps for fixing the casting on the workbench 2. The clamp in this embodiment includes a first electric push rod 10 fixed on the driving disk 3. The first electric push rod 10 is fixed with a clamp 4 at one end close to the workbench 2. When the stamping work starts, the first electric push rod 10 is started to drive the clamp 4 to move, and the two clamps 4 cooperate to clamp the casting. After the stamping work is completed, the first electric push rod 10 drives the clamp 4 back to the initial position. Of course, the clamp can also be other structures without too many restrictions.

[0081] Specifically, the stamping unit includes:

[0082] A punching head 5, wherein a telescopic guide rod 7 is fixedly connected between the punching head 5 and the frame 1, and can be fixed by screws. A first tension spring 6 is fixedly connected between the shell of the telescopic guide rod 7 and the punching head 5, and can be fixed by welding. The first tension spring 6 exerts an upward pulling force on the punching head 5;

[0083] The driving mechanism 8 is used to drive the punch head 5 to approach the workbench 2. In this embodiment, the driving mechanism 8 includes:

[0084] The second motor 19 fixed to the frame 1 can be fixed by bolts;

[0085] A disc eccentrically fixed to the output shaft of the second motor 19, the disc being composed of a first disc body 13 and a second disc body 14, one end of the first disc body 13 being hinged to the second disc body 14 at a hinge point B, and the second disc body 14 being fixed to the output shaft of the second motor 19;

[0086] A worm 15 is rotatably mounted on one side of the second disc 14. A worm wheel 16 cooperating with the worm 15 is also rotatably mounted on one side of the second disc 14. One end of a first connecting rod 17 is eccentrically hinged to the end surface of the worm wheel 16. The other end of the first connecting rod 17 is hinged to the first disc 13. When in use, by rotating the worm 15, the worm 15 drives the worm wheel 16 to rotate, and the worm wheel 16 drives the first connecting rod 17 to move. The first connecting rod 17 drives the first disc 13 to rotate around the hinged end with the second disc 14, adjusting the distance between the first disc 13 and the second disc 14. Therefore, when the entire disc rotates, its maximum rotation diameter changes;

[0087] During the stamping operation, the disc is driven to rotate by the second motor 19. When the disc rotates eccentrically, the punch head 5 is pushed downward to stamp the casting. As the disc continues to rotate and the punch head 5 moves up and down with the cooperation of the first tension spring 6, the casting is repeatedly stamped with good effect. By rotating the worm 15 to adjust the maximum rotation diameter of the disc, the stroke of the punch head 5 can be adjusted to adapt to castings of different sizes or adjust the stamping force of the punch head 5 on the casting.

[0088] Furthermore, the deburring unit includes:

[0089] a third motor 12 fixed to the frame 1;

[0090] A receiving frame 11 is provided on one side of the workbench 2 and is used to receive the castings stamped on the workbench 2. A brush is installed on the inner wall of the receiving frame 11. The receiving frame 11 is fixed to the output shaft of the third motor 12.

[0091] The stamped castings that slide down from the workbench 2 fall into the containing frame 11, and then the containing frame 11 is driven by the third motor 12 to change the speed of rotation. The castings in the containing frame 11 are deburred by the action of the brush. It should be explained that the speed change of the containing frame 11 causes the castings to move relative to the brush under the action of inertia, centrifugal force, etc.

[0092] Furthermore, the deburring unit also includes a cover 26 and a moving mechanism. The cover 26 is arranged above the containing frame 11, and brushes are evenly provided on the lower surface of the cover 26. The moving mechanism is installed on the frame 1 and drives the connected cover 26 to drive the cover 26 to move closer to or away from the containing frame 11. In this embodiment, the moving mechanism includes a fifth motor and a threaded rod 27. The threaded rod 27 is vertically rotated and installed on the frame 1. The threaded rod 27 passes through the cover 26 and is threadedly connected thereto. The fifth motor is a forward and reverse motor. The fifth motor is fixed on the frame 1 to drive the threaded rod 27 to rotate. During the deburring operation, the threaded rod 27 is driven to rotate by the fifth motor, and the threaded rod 27 drives the cover 26 to move toward the containing frame 11 and cover the top of the containing frame 11. On the one hand, it prevents the casting from falling out when the containing frame 11 rotates. On the other hand, the brush on the cover 26 can further brush the casting to fully remove burrs.

[0093] In this embodiment, the metal casting processing and automatic shaping equipment further includes a loading unit, which includes:

[0094] A barrel 20 is provided on the side of the workbench 2 away from the deburring unit. The size of the barrel 20 is selected according to the size of the casting. Multiple castings can be manually stacked from top to bottom in the barrel 20. Both ends of the barrel 20 are open. A second electric push rod 21 is fixed to the frame 1. The telescopic end of the second electric push rod 21 is fixedly connected to the barrel 20. The second electric push rod 21 is used to drive the barrel 20 to move upward or downward;

[0095] A sliding plate 24 is provided below the barrel 20. A second baffle is provided on both the front and rear sides of the sliding plate 24 to prevent the casting from falling from the side of the sliding plate 24. One end of the sliding plate 24 is hinged to the workbench 2, and the other end of the sliding plate 24 is hinged to one end of the connecting plate 23. The other end of the connecting plate 23 is hinged to the frame 1. A second tension spring 22 is fixedly connected between the connecting plate 23 and the frame 1. Figure 1 As shown, according to the size of the casting, the distance between the bottom end of the barrel 20 and the slide plate 24 can be adjusted by the second electric push rod 21, so that when stamping, the distance between the bottom end of the barrel 20 and the slide plate 24 is smaller than the size of the casting, so that the casting will not fall from the barrel 20 onto the slide plate 24. After the stamping work is completed, the first motor 18 drives the drive disk 3 to rotate clockwise, so that the workbench 2 tilts, and the stamped casting on the workbench 2 falls into the containing frame 11. When the drive disk 3 drives the pin shaft 9 to rotate as shown in FIG. Figure 5 In the position shown, the pin shaft 9 is at the lowest point, and the workbench 2 drives the slide plate 24 to move, so that the distance between the slide plate 24 and the bottom end of the barrel 20 increases, and a casting completely separates from the barrel 20 and falls onto the slide plate 24, and moves along the slide plate 24 toward the workbench 2. At the same time, the drive disk 3 continues to rotate, driving the slide plate 24 to move closer to the bottom end of the barrel 20, and the distance between the two is reduced. The casting cannot fall, and in this way, the castings can be delivered to the workbench 2 one by one, with a high degree of automation and improved work efficiency.

[0096] Furthermore, a toggle assembly is included for pushing the casting on the slide plate 24 onto the workbench 2, and the toggle assembly includes:

[0097] A fourth motor fixed on the second baffle on one side of the slide plate 24, the fourth motor is a forward and reverse motor;

[0098] The lever 25 fixed on the output shaft of the fourth motor moves the casting to the end where the slide plate 24 is hinged to the workbench 2, and the lever 25 is driven by the fourth motor to rotate, and the lever 25 pushes the casting to move onto the workbench 2.

[0099] Example 2

[0100] This embodiment is based on embodiment 1. Figure 6-7As shown, further, the deburring unit also includes a motion unit, which includes an electromagnet 33 and a power supply component. The electromagnet 33 is fixedly mounted on the cover plate 26. When the electromagnet 33 is energized, it can generate attraction to the casting. The power supply component includes a power supply, a sliding rheostat 32 and an adjustment mechanism. The power supply, the sliding rheostat 32 and the electromagnet 33 are connected in series. The adjustment mechanism is used to change the resistance of the sliding rheostat 32. The adjustment mechanism includes a sixth motor 28, a turntable 29, a second connecting rod 30 and a connecting block 31. The sixth motor 28 is fixed to the frame 1 and can be fixed by screws. The turntable 29 is fixed on the output shaft of the sixth motor 28 and can be fixed by welding. One end of the second connecting rod 30 is eccentrically hinged on the turntable 29, and the other end of the second connecting rod 30 is hinged to the connecting block 31. The connecting block 31 is fixedly connected to the sliding vane of the sliding rheostat 32.

[0101] In specific implementation, when deburring, the electromagnet 33 is energized to generate an upward force on the metal workpiece. If the upward force is equal to the gravity of the metal workpiece, the casting can be placed in a state close to suspension. As the brush moves, the casting moves irregularly, and the brush can fully deburr the casting. The turntable 29 is driven to rotate by the sixth motor 28, and the turntable 29 drives the second connecting rod 30 to move. The second connecting rod 30 drives the connecting block 31 to reciprocate, and the connecting block 31 drives the slider of the sliding rheostat 32 to reciprocate, so that the current passing through the electromagnet 33 changes repeatedly, and the attraction of the electromagnet 33 to the casting continues to change. The casting moves back and forth irregularly in the vertical direction, making the deburring more sufficient.

[0102] In summary, the present invention provides an automated shaping equipment for metal castings, which comprises a frame 1, a stamping unit, a workbench 2, a deburring unit and a transfer unit. During the stamping operation, the workbench 2 is kept horizontal, the casting is placed on the workbench 2, and then the casting is stamped by the stamping unit. After the stamping is completed, the transfer unit drives the workbench 2 to tilt toward the deburring unit, and the stamped casting on the workbench 2 slides to the deburring unit. No manual transfer is required, which reduces the workload and work intensity of the workers and improves work efficiency. A stamping unit is provided, the stamping unit comprises a stamping head 5 and a driving mechanism 8, the driving mechanism 8 comprises a second motor 19, a disc, a worm 15, a worm gear 16 and a first connecting rod 17.
