Description

Technical Field

[0001] This invention relates to the field of stamping equipment technology, and in particular to a stamping equipment for processing aluminum alloy parts for magnetic levitation vacuum pumps. Background Technology

[0002] The stamping equipment used in the processing of aluminum alloy parts for magnetic levitation vacuum pumps is primarily used for the efficient and precise forming of various aluminum alloy components. This equipment applies pressure to the aluminum material through a die, rapidly shaping it into the desired structure, replacing traditional cutting processes and significantly improving production efficiency. The stamping process can form complex curved surfaces and precision structures, ensuring dimensional stability of parts and meeting the airtightness and strength requirements of vacuum pumps. It is a key piece of equipment for improving the processing quality and production capacity of aluminum alloy parts.

[0003] Traditional stamping equipment is widely used in the metal processing industry, but due to limitations in its structure and working principle, it often presents some significant problems. Existing aluminum alloy parts stamping equipment still relies on manual removal of the workpiece after forming, posing significant efficiency and safety risks. In the traditional operating mode, workers must manually remove the workpiece after the stamping die opens, which not only limits the pace and makes it difficult to match the production rhythm of high-speed stamping, but also easily leads to equipment downtime due to operational delays. More seriously, in the high-temperature aluminum parts processing and die closing areas, operators face risks such as mechanical pinching and burns; even with the addition of photoelectric protection devices, injuries from misoperation cannot be completely avoided. Summary of the Invention

[0004] In view of the problem that existing stamping equipment relies on manual removal of workpieces, a stamping equipment for processing aluminum alloy parts of magnetic levitation vacuum pumps is proposed.

[0005] Its purpose is to enable the stamping equipment to automatically pick up materials after the mold is opened and to adapt to workpieces of different sizes.

[0006] The technical solution of the present invention is a stamping equipment for processing aluminum alloy parts of magnetic levitation vacuum pump, including a machine tool, a lower die set on the worktable of the machine tool, an upper die set on the machine tool above the lower die, a push rod set inside the lower die, and a blanking mechanism symmetrically set on both sides of the lower die.

[0007] The blanking mechanism includes a short arm located at the edge of the lower die, a torsion spring located at the bottom end of the short arm near the lower die, with both ends of the torsion spring fixedly connected to the short arm and the lower die respectively, a ratchet assembly located at the bottom end of the short arm away from the lower die, a toothed ring located outside the ratchet assembly, racks symmetrically located on both sides of the upper die, with the racks meshing with the toothed rings, a long arm located on the side of the lower die away from the short arm, a connecting rod located in the middle of the long arm and the short arm, with both ends of the connecting rod rotatably connected to the long arm and the short arm respectively, and a telescopic unit located at the top of the long arm and the short arm.

[0008] The short arm rotates while driving the long arm to rotate via a connecting rod. The movement of the upper mold drives the rack to move up and down. The movement of the rack drives the gear ring to rotate. The gear ring drives the short arm to rotate via a ratchet assembly. The torsion spring allows the short arm to reset after releasing external force interference. The push rod lifts the workpiece when the upper mold moves upward.

[0009] Furthermore, the ratchet assembly consists of a grooved wheel and a pawl, with the outer side of the grooved wheel fixedly connected to the toothed ring.

[0010] Furthermore, the telescopic unit includes two outer shells respectively disposed at the top of the long arm and the short arm, a lead screw disposed on the outer side of the outer shell, a slider disposed on the outer side of the lead screw, a sliding hole opened on the side of the outer shell near the lead screw, the outer side of the slider being slidably connected to the sliding hole, an inclined block disposed on the inner wall of the outer shell near the sliding hole, a telescopic rod disposed inside the outer shell, a swing fork disposed on the end of the telescopic rod away from the upper mold, springs symmetrically disposed on both sides of the swing fork, the two ends of the springs being fixedly connected to the swing fork and the telescopic rod respectively, a cover disposed at the top of the outer shell, a moving block disposed in the middle of the cover, an elastic rope disposed at the bottom of the moving block, the bottom end of the elastic rope being fixedly connected to the swing fork, a drive rod disposed at the top of the cover, a telescopic shaft disposed inside the drive rod, a driven wheel disposed on the telescopic shaft near the lower mold, a drive wheel disposed on the telescopic rod near the lower mold, and a swing rod disposed together on the side of the two telescopic units near the lower mold.

[0011] Furthermore, a short pin is provided on the top of the moving block, a drive groove is provided on the outer side of the drive rod, the inner wall of the drive groove is slidably connected to the short pin, and a hexagonal hole is provided at the end of the drive rod near the driven wheel, the inner wall of the hexagonal hole is slidably connected to the telescopic shaft.

[0012] Furthermore, a slide rail is provided on the inner wall of the middle part of the cover, and the outer side of the moving block is slidably connected to the slide rail.

[0013] Furthermore, the driving wheel has an annular groove in the middle, and the driven wheel has a circular plate in the middle, with the circular plate and the annular groove cooperating with each other.

[0014] Furthermore, the swing rod consists of a high rod and a low rod. The high rod is fixedly connected to the drive wheel corresponding to the long arm, and the low rod is fixedly connected to the drive wheel corresponding to the short arm. A guide groove is provided on the side of the high rod near the lower mold, and the low rod is slidably connected to the guide groove.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. By setting up a feeding mechanism, the automatic material handling function of the processed workpiece is realized. After the stamping process is completed, the mechanism takes the workpiece out of the coverage area and transports it to the designated area without manual operation. Automatic material handling avoids the need for operators to enter the dangerous area of ​​the equipment with their hands, and eliminates the safety hazards such as squeezing and shearing that may be caused by manual material handling. At the same time, the material handling process is consistent with the equipment operation rhythm, reducing production waiting time and enabling the stamping operation to be carried out continuously. During equipment operation, the material handling action is stable and repetitive, reducing production fluctuations caused by differences in human operation, thereby improving the overall operation efficiency.

[0017] 2. By setting up a telescopic unit, the equipment can adapt to and pick up workpieces of different sizes. This unit can be adjusted according to the actual size of the workpiece to ensure that the picking action matches the workpiece. During the stamping operation, the operator sets the telescopic unit according to the workpiece specifications to enable it to complete positioning and gripping. This design allows the equipment to handle workpieces of various sizes, expands its application range, and ensures the accuracy and stability of the action. The introduction of the telescopic unit makes the equipment flexible when switching between different specifications of workpieces.

[0018] 3. By setting a swing arm, the workpiece is lifted after stamping. The swing arm forms an inclination angle during its movement, causing the workpiece to slide off its surface due to gravity and leave the mold area. This mechanism integrates the workpiece removal process into the equipment's operating rhythm, and unloading can be completed without manual intervention. The movement trajectory of the swing arm is coordinated with the stamping action to ensure that the workpiece is lifted and guided to the set position at the appropriate time. This design avoids the operator's hands from entering the danger zone and reduces the risk of operation. Attached Figure Description

[0035] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0036] Example 1, referring to Figures 1-14This invention provides a stamping device for processing aluminum alloy parts for a magnetic levitation vacuum pump, comprising a machine tool 1, a lower die 2 fixedly connected to the worktable of the machine tool 1, an upper die 3 fixedly connected to the machine tool 1 above the lower die 2, a push rod 4 slidably connected inside the lower die 2, and blanking mechanisms 5 symmetrically installed on both sides of the lower die 2. The blanking mechanism 5 includes a short arm 51 rotatably connected to the edge of the lower die 2, a torsion spring 52 sleeved on the bottom end of the short arm 51 near the lower die 2, with both ends of the torsion spring 52 fixedly connected to the short arm 51 and the lower die 2 respectively, a ratchet assembly 53 fixedly connected to the bottom end of the short arm 51 away from the lower die 2, and a toothed ring 54 fixedly connected to the outside of the ratchet assembly 53. The racks 55 on both sides of the upper mold 3 are meshed with the toothed rings 54 and are rotatably connected to the long arm 56 on the side of the lower mold 2 away from the short arm 51. They are rotatably connected to the connecting rod 57 in the middle of the long arm 56 and the short arm 51. The two ends of the connecting rod 57 are rotatably connected to the long arm 56 and the short arm 51 respectively, and are also assembled with the telescopic unit on the top of the long arm 56 and the short arm 51. When the short arm 51 rotates, it drives the long arm 56 to rotate through the connecting rod 57. The movement of the upper mold 3 drives the racks 55 to move up and down. The movement of the racks 55 drives the toothed rings 54 to rotate. The toothed rings 54 drive the short arm 51 to rotate through the ratchet group 53. The torsion spring 52 makes the short arm 51 reset after the external force intervention is released. When the upper mold 3 moves up, the ejector rod 4 lifts the workpiece.

[0037] Specifically, after the mold opens, the upper mold 3 moves upward, and the ejector pin 4 moves upward at the same time to lift the workpiece. The upper mold 3 drives the rack 55 to move together. After the rack 55 moves a certain distance, it meshes with the gear ring 54 and makes it rotate. The gear ring 54 drives the short arm 51 to rotate through the ratchet assembly 53. Due to the unidirectional transmission characteristic of the ratchet assembly 53, the rack 55 can only drive the short arm 51 to rotate through the gear ring 54 and the ratchet assembly 53 when it moves upward. At the same time as the short arm 51 rotates, the torsion spring 52 stores force. After the rack 55 moves downward to disengage from the gear ring 54, the short arm 51 returns to its original position under the action of the torsion spring 52. At the same time as the short arm 51 rotates, it drives the long arm 56 to rotate together through the connecting rod 57.

[0038] Reference Figures 3-5 The ratchet assembly 53 consists of a grooved wheel and a pawl, with the outer side of the grooved wheel fixedly connected to the toothed ring 54.

[0039] Specifically, when the rack 55 moves upward and drives the gear ring 54 to rotate, the ratchet assembly 53 transmits the force to the short arm 51. When the rack 55 moves downward, the ratchet assembly 53 will not drive the short arm 51 to rotate.

[0040] Example 2, refer to Figures 1-14This is the second embodiment of the present invention, which differs from the first embodiment in that: the telescopic unit includes two outer shells 58 respectively fixedly connected to the tops of the long arm 56 and the short arm 51; a lead screw 59 rotatably connected to the outside of the outer shell 58; a slider 510 rotatably connected to the outside of the lead screw 59; a sliding hole 511 opened on the side of the outer shell 58 near the lead screw 59; the outside of the slider 510 slidably connected to the sliding hole 511; an inclined block 512 fixedly connected to the inner wall of the outer shell 58 near the sliding hole 511; a telescopic rod 513 slidably connected inside the outer shell 58; a swing fork 514 rotatably connected to the end of the telescopic rod 513 away from the upper mold 3; and springs 515 symmetrically fixedly connected to both sides of the swing fork 514. The two ends of the spring 515 are fixedly connected to the swing fork 514 and the telescopic rod 513 respectively. The cover 516 is fixedly connected to the top of the outer shell 58. The moving block 517 is slidably connected to the middle of the cover 516. The elastic rope 518 is fixedly connected to the bottom of the moving block 517. The bottom end of the elastic rope 518 is fixedly connected to the swing fork 514. The drive rod 519 is rotatably connected to the top of the cover 516. The telescopic shaft 520 is slidably connected inside the drive rod 519. The driven wheel 521 is fixedly connected to the telescopic shaft 520 near the lower mold 2. The drive wheel 522 is rotatably connected to the telescopic rod 513 near the lower mold 2. The swing rod 523 is rotatably connected to both telescopic units near the lower mold 2.

[0041] Specifically, when the upper mold 3 moves upward, under the action of the gear and gear ring 54, the long arm 56 and the short arm 51 rotate upward, simultaneously driving the corresponding telescopic units to move. The two ends of the swing rod 523 will rotate relative to the connection points of the long arm 56 and the short arm 51, and the driving wheel 522 will also rotate relative to the corresponding driven wheel 521. The swing rod 523 will extend and retract to adapt to the change in the top distance of the long arm 56 and the short arm 51 after rotation. At this time, the driving wheel 522 drives the driven wheel 521 to rotate. While the driven wheel 521 rotates, it drives the drive rod 519 to rotate through the telescopic shaft 520. Simultaneously, the moving block 517 is driven to move closer to the drive wheel 522. The moving block 517 pulls the swing fork 514 through the elastic rope 518. The longer the moving distance of the moving block 517, the greater the traction force on the swing fork 514. After the traction force on the swing fork 514 exceeds the thrust of the spring 515, it will rotate around the connection point with the telescopic rod 513. After the swing fork 514 rotates a certain angle, it releases its engagement with the inclined block 512. At this time, the telescopic rod 513 will move closer to the lower mold 2 under the action of the elastic rope 518 until the swing fork 514 engages with the slider 510. As the telescopic rod 513 extends, it... The driving wheel 522 drives the driven wheel 521 and the telescopic shaft 520 to move together, keeping the driving wheel 522 and the driven wheel 521 engaged at all times. This also drives the swing rod 523 to move together, extending the swing rod 523 into the space between the workpiece and the lower die 2. As the long arm 56 and the short arm 51 rotate to a vertical position, the height of the swing rod 523 gradually increases, lifting the workpiece. At this point, the swing rod 523 is tilted, and the workpiece slides out of the area between the upper die 3 and the lower die 2 under the influence of gravity. By rotating the lead screw 59, the slider 510 can be driven to rotate, moving away from the lower die 2. During movement, the extension distance of the telescopic rod 513 is reduced. By controlling the position of the slider 510, the extension length of the telescopic rod 513 can be controlled. When the upper mold 3 moves down, the short arm 51 is reset under the action of the torsion spring 52. At this time, the driven wheel 521 reverses, causing the moving block 517 to move away from the driving wheel 522. The moving block 517 pulls the swing fork 514 through the elastic rope 518 until the swing fork 514 disengages from the slider 510, causing the telescopic rod 513 to retract. After the swing fork 514 retracts to its maximum stroke along with the telescopic rod 513, the swing fork 514 cooperates with the inclined block 512 to limit the telescopic rod 513.

[0042] Reference Figure 10 and Figure 11 The top of the moving block 517 is provided with a short pin, and the outer side of the drive rod 519 is provided with a drive groove. The inner wall of the drive groove is slidably connected to the short pin. The end of the drive rod 519 near the driven wheel 521 is provided with a hexagonal hole. The inner wall of the hexagonal hole is slidably connected to the telescopic shaft 520.

[0043] Specifically, as the drive rod 519 rotates, it presses the short pin through the drive groove, causing the moving block 517 to be positioned, and the telescopic shaft 520 can extend and retract along the hexagonal hole.

[0044] Reference Figure 11 The inner wall of the middle part of the cover 516 is provided with a slide rail, and the outer side of the moving block 517 is slidably connected to the slide rail.

[0045] Specifically, the cover 516 constrains the moving block 517 through the slide rail, so that the moving block 517 moves along the slide rail after being subjected to force.

[0046] Reference Figure 12 The driving wheel 522 has an annular groove in the middle, and the driven wheel 521 has a circular plate in the middle, with the circular plate and the annular groove cooperating with each other.

[0047] Specifically, through the cooperation of the annular groove and the circular plate, the driving wheel 522 moves along the axis while driving the driven wheel 521 to move together.

[0048] Reference Figures 3-12 The swing rod 523 consists of a high rod and a low rod. The high rod is fixedly connected to the drive wheel 522 corresponding to the long arm 56, and the low rod is fixedly connected to the drive wheel 522 corresponding to the short arm 51. A guide groove is provided on the side of the high rod near the lower mold 2, and the low rod is slidably connected to the guide groove.

[0049] Specifically, the overall length and tilt angle of the swing arm 523 can be changed according to the movement state of the long arm 56 and the short arm 51, and the rest of the structure is the same as that of Embodiment 1.

[0050] Based on embodiments 1-2, the working principle of this invention is as follows: After the workpiece is stamped, the upper die 3 moves upward. After the die opens, the workpiece is lifted upward by the ejector pin 4 of the die, separating it from the die cavity. After the upper die 3 moves upward a certain distance, it drives the gear ring 54 to rotate via the rack 55. The gear ring 54 drives the short arm 51 to swing upward via the ratchet assembly 53. The long arm 56 swings together with the short arm 51 under the action of the connecting rod 57. While the long arm 56 and the short arm 51 are swinging, they interact with the drive wheel 522 and the swing rod 523. A relative rotation occurs between the driven wheel 521 and the driven wheel 522. The driven wheel 522 drives the moving block 517 to move via the telescopic shaft 520 and the drive rod 519. After the moving block 517 is displaced, it pulls the swing fork 514 through the elastic rope 518, causing the swing fork 514 to disengage from the inclined block 512. At this time, the telescopic rod 513 extends under the action of the elastic rope 518, and the swing fork 514 also moves together until the swing fork 514 engages with the slider 510 and the telescopic rod 513 stops. When the telescopic rod 513 extends, it drives the swing rod 523 to extend as well. The swing rod 523 extends and is positioned below the workpiece. At this time, the long arm 56 and short arm 51 continue to swing, and the overall height of the swing rod 523 rises, lifting the workpiece and causing it to slide down along the inclined top surface of the swing rod 523. When the upper mold 3 moves downward, the rack 55 moves downward until it disengages from the gear ring 54. At this time, the long arm 56 and short arm 51 return to their original positions. The drive wheel 522 then drives the driving wheel and drive rod 519 to reverse direction, and the moving block... 517 moves in the opposite direction and pulls the swing fork 514 in the opposite direction through the elastic rope 518 until the swing fork 514 disengages from the slider 510. Then the telescopic rod 513 moves in the direction of the traction force until the swing fork 514 engages with the inclined block 512, completing the retraction of the telescopic rod 513 and the swing rod 523. By rotating the lead screw 59, the slider 510 can be moved, which can control the extension length of the telescopic rod 513, so that the swing rod 523 can extend to different distances to adapt to workpieces of different sizes.

[0051] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
