Description

Technical Field

[0001] This invention relates to the field of press technology, specifically to a forming press for processing metal discs. Background Technology

[0002] Presses are core equipment used in industrial manufacturing to apply pressure to materials, causing them to undergo plastic deformation or separation. They are widely used in metal stamping, forging, stretching, extrusion and other processes.

[0003] In existing presses, when processing circular workpieces, a single-stage punching process is typically used to form metal gaskets. This process significantly improves processing and production efficiency. However, punching the outer circle and inner hole simultaneously causes the inner and outer cutting edges to be subjected to punching forces simultaneously, with opposite force directions. This results in high stress concentration during punching, making the die cutting edges more prone to wear and chipping. Furthermore, the instantaneous deformation, stretching, and springback of the material are more pronounced during a single punching operation, which is detrimental to improving the accuracy of the formed workpiece. However, when using a separate processing process, the defective connection device between the outer circle punching and inner hole punching machines requires frequent transfer of the disc to the inner hole punching machine after the outer circle punching operation, leading to a decrease in processing efficiency. Therefore, we propose a forming press for processing metal discs to solve the above-mentioned defects. Summary of the Invention

[0018] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0020] In this invention, when the metal disc is transferred to the top of the first plate, the electric cylinder controls the sliding bar to return to its original position. By pushing the corner shaft, the pressure bar pushes the unloading frame downward.

During the operation of the second pressure cylinder group, the flip plate is swung onto the second base, so that the metal disc is placed in a horizontal state and punching operation is performed directly. After the smooth connection operation of the metal disc transfer, dropping and limiting installation is completed, the punching operation is performed, which further improves the efficiency required for production and processing.

The rack 403 is slidably connected to the side of the second base body.

[0042] The transfer mechanism 5 includes a mounting base 501 disposed on the side of the first base 304, a rotating shaft 502 rotatably disposed on the mounting base 501, a first torsion spring 503 disposed at the connection between the lower part of the rotating shaft 502 and the mounting base 501, and a mounting arm 504 fixedly connected to the upper part of the rotating shaft 502.

[0043] A curved strip 505 is fixedly connected to one end of the mounting arm 504 away from the rotating shaft 502. A lever 506 is fixedly connected to one side of the top of the rotating shaft 502. The lever 506 abuts against the surface of the wedge block 303. A curved arm 507 is rotatably connected to one side of the curved strip 505. A second torsion spring 508 is provided at the connection between the curved arm 507 and the curved strip 505. A connecting frame 509 is rotatably mounted on the curved strip 505. The connecting frame 509 is U-shaped. One side of the connecting frame 509 is fixedly connected to the curved arm 507.

[0044] The carrying positioning mechanism 6 includes a support frame 601, which is inclined. The inclination angle of the middle part of the support frame 601 is adapted to the rotation trajectory of the connecting frame 509 around the mounting base 501. The support frame 601 is fixedly connected to the machine base 1. A first plate 602 and a second plate 603 are fixedly installed on the side of the support frame 601, respectively. The second plate 603 is thinner than the first plate 602.

[0045] A spring telescopic rod 604 is fixedly installed on one side of the support frame 601 relative to the second plate 603. An unloading frame 605 is fixedly connected to the top of the spring telescopic rod 604. The unloading frame 605 is hollow inside. A trigger shaft 606 is fixedly connected to the output shaft of the spring telescopic rod 604 near the unloading frame 605. The inner wall of the unloading frame 605 abuts against the curved arm 507.

[0046] In this embodiment, during the stamping process, the metal strip is first passed through the middle of the support frame 801 and inserted between the moving roller 803 and the fixed roller 802. The bottom of the metal strip is supported by two guide frames 7 and is located on the surface of the first base 304. First, the first pressure cylinder group 3 is activated, and the stamping head 302 outputs downward to perform a stamping operation on the metal strip. During the downward movement of the stamping head 302, the inclined wedge block 303 on its side contacts the dial shaft 506 and squeezes the dial shaft 506, causing the dial shaft 506 to drive the rotating shaft 502 to rotate around the mounting base 501. During the process, the first torsion spring 503 at the connection between the rotating shaft 502 and the mounting base 501 is squeezed. The mounting arm 504 on the rotating shaft 502 drives the receiving frame 509 to move synchronously. The receiving frame 509 is moved away from below the stamping head 302 and moves closer to the unloading frame 605 to avoid obstructing the downward pressing path of the stamping head 302. Finally, the stamping head 302 contacts the metal strip and stamps a round piece off the metal strip.

[0047] In this embodiment, the first cylinder 301 controls the punch head 302 to move upward to return to its original position. During the process, the punch head 302 carries a punched disc to rise synchronously through the energization of the built-in electromagnet. At this stage, the punch head 302 synchronously drives the wedge block 303 to rise. The wedge block 303 gradually releases the pressure on the dial shaft 506. After the punch head 302 is fully raised, the rotating shaft 502 rotates to the initial position under the action of the first torsion spring 503. At the same time, the rotating shaft 502 drives the receiving frame 509 to swing to directly below the punch head 302. At this time, the built-in electromagnet of the punch head 302 is de-energized, and the punched disc loses its magnetic attraction and falls downward into the receiving frame 509, completing the collection operation after the disc is punched. When the punch head 302 continues to perform the downward pressing operation, through the transmission of the wedge block 303 and the dial shaft 506, the rotating shaft 502 drives the receiving frame 509 to swing to the unloading point, so that the metal disc is transferred.

[0048] A horizontal bar 607 is slidably mounted on the support frame 601. A pressure bar 608 is provided on the side of the horizontal bar 607 near the trigger shaft 606. The pressure bar 608 is arranged in a downward curved shape and is open on both sides. The inner surface of the pressure bar 608 abuts against the trigger shaft 606. A return spring 609 abuts against the side of the horizontal bar 607 away from the pressure bar 608. The return spring 609 is movably sleeved on the support frame 601. A corner shaft 610 is fixedly connected to the side of the horizontal bar 607.

[0049] An L-plate 611 is provided on the side of the first plate 602 near the second plate 603. The bottom of the L-plate 611 is fixedly connected to the first plate 602 and is suspended on the side. A sliding strip 612 is slidably provided on the outer surface of the L-plate 611. A push roller 613 is rotatably provided on the sliding strip 612. The push roller 613 is located between the first plate 602 and the L-plate 611.

[0050] An electric cylinder 614 is fixedly installed on one side of the first plate 602 relative to the L plate 611. The output shaft of the electric cylinder 614 is fixedly connected to the slide bar 612, and the end of the corner shaft 610 abuts against the side of the slide bar 612.

[0051] The bottom of the second plate 603 is rotatably connected to a flap 615. A punch 616 is opened through the center of the flap 615. Mounting shafts 617 are symmetrically installed on the surface of the flap 615 relative to the two sides of the punch 616. Limiting members 618 are respectively provided on one side of the flap 615 relative to the mounting shafts 617. The limiting members 618 are slidably connected to the mounting shafts 617. A compression spring 619 is movably sleeved on the mounting shafts 617. The compression spring 619 abuts against the limiting members 618.

[0052] In this embodiment, when the metal disc is transferred to the unloading point, the bent arm 507 on the side of the receiving frame 509 inserts into the unloading frame 605 during the swinging process. At this time, the output axis of the electric cylinder 614 is retracted inward, pulling the sliding bar 612 to slide along the L plate 611. During this stage, the sliding bar 612 pushes the corner shaft 610 to move, and the corner shaft 610 drags the crossbar 607 on the support frame 601 to move in the same direction. During the movement, the pressure bar 608 at one end of the crossbar 607... The trigger shaft 606 is pushed downward, which simultaneously drives the unloading frame 605 to move downward. During the downward movement of the unloading frame 605, the bent arm 507 is moved, causing the bent arm 507 to swing downward. During this process, the bent arm 507 overcomes the tension of the second torsion spring 508, causing the receiving frame 509 to rotate. The open end of the receiving frame 509 swings downward, and finally the bottom end of the receiving frame 509 contacts the upper surface of the first plate 602, and the metal disc inside falls onto the first plate 602.

[0053] In this embodiment, the metal disc slides down between the first plate 602 and the L plate 611. At this time, the electric cylinder 614 is controlled to output outward, and the push roller 613 pushes the falling metal disc to move laterally towards the second plate 603. The outer edge of the metal disc first contacts the edge of the two symmetrically arranged limiting members 618 that are close to each other, and squeezes them apart along the surface of the limiting members 618, so that the two limiting members 618 are far apart. After the metal disc passes the edge, it contacts the inner surface of the limiting member 618. At this time, the pushing force of the metal disc on the limiting member 618 gradually decreases, and the compression spring 619 exerts force to press the two limiting members 618, limiting the metal disc and making it wrapped between the two limiting members 618.

[0054] A gear 620 is fixedly connected to one side of the bottom of the flip plate 615. The gear 620 meshes with the rack 403, and the punch 616 is axially opposite to the second base 404.

[0055] The roller conveying mechanism 8 includes a support frame 801 mounted on the machine base 1. The upper and lower parts of the support frame 801 are respectively rotatably equipped with a fixed roller 802 and a movable roller 803. The two sides of the movable roller 803 are rotatably sleeved with displacement blocks 804, and the displacement blocks 804 are slidably connected to the support frame 801.

[0056] One of the shifting blocks 804 is connected to a drive motor 805 at its top. The output end of the drive motor 805 is connected to a pulley group 806. One end of the pulley group 806 relative to the drive motor 805 is connected to the moving roller 803. The top of the shifting block 804 abuts against a clamping spring 807, which is movably sleeved on the support frame 801.

[0057] In this embodiment, after the metal disc is fixed on the flip plate 615, the second cylinder 401 controls the punching head 402 to descend. During the process, the rack 403 drives the gear 620 to rotate, causing the flip plate 615 to flip the metal disc outward. The flip plate 615 finally falls onto the second base 404, and the mounting shaft 617 is embedded in the slot 405 to keep the flip plate 615 horizontal. Then, the punching head 402 contacts the metal disc, so that one side of it is in close contact with the flip plate 615, and finally completes the punching operation on the metal disc. After completion, the punching head 402 rises back, and the built-in electromagnet removes the metal disc from between the two limiting members 618.

[0058] The method of use and advantages of the present invention: The forming press for processing metal discs operates as follows:

[0059] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 As shown:

[0060] S1: The metal strip passes through the support frame 801, is fed in by the fixed roller 802 and the moving roller 803, and is supported on the first base 304 by the guide frame 7. The first pressure cylinder group 3 drives the punch head 302 to move downward. The side wedge block 303 squeezes the pivot shaft 506, causing the pivot shaft 502 to drive the connecting frame 509 to swing open and avoid the punching path. The punch head 302 punches the metal strip to drop it. Then the electromagnet is energized to attract the disc and rise with the punch head 302.

[0061] S2: After the punch head 302 rises, the wedge block 303 releases the pivot 506. Under the action of the torsion spring, the pivot 502 drives the receiving frame 509 to swing back to directly below the punch head 302. The electromagnet is de-energized, and the round piece falls into the receiving frame 509. When punching again, the receiving frame 509 swings to the unloading position, and the bent arm 507 extends into the unloading frame 605.

[0062] S3: The electric cylinder 614 pulls the sliding bar 612, which drives the pressure bar 608 to press down the trigger shaft 606 through the corner shaft 610, causing the unloading frame 605 to move down and the bending arm 507 to move. The receiving frame 509 flips over to dump the material, and the round piece falls onto the plate. The push roller 613 pushes the round piece toward the limiting member 618, and the compression spring 619 makes the limiting member 618 clamp the round piece.

[0063] S4: Flipping and Secondary Punching The second cylinder 401 drives the punching head 402 downward, the rack 403 drives the gear 620 to rotate, causing the flip plate 615 to flip the round piece outward and flatten it. The punching head 402 punches the round piece a second time. After completion, the punching head 402 rises back, and the electromagnet attracts the finished round piece for removal.

[0064] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the invention.
