Description

Technical Field

[0001] This invention relates to the field of stamping equipment technology, specifically to a multi-angle stamping equipment for molds with pneumatic linkage perforation. Background Technology

[0002] Metal stamping dies are tools used to shape blanks into parts of specific shapes and sizes. Stamping dies serve as a core production tool for aluminum alloy casings. Aluminum alloy casings are widely used in electronics, automotive parts, and home appliances due to their lightweight, high strength, and excellent heat dissipation. After initial stamping, aluminum alloy casings still require multi-angle punching. In the production process of aluminum alloy stamping dies, for dies with thinner walls, pre-reserved punching holes can be achieved through stamping equipment. Stamping and punching offer advantages such as high efficiency, low cost, and strong consistency, providing reliable reference positioning for subsequent stamping.

[0003] In response to this, this application designs a multi-angle stamping processing equipment for molds with pneumatic linkage perforation. Traditional stamping processing equipment, when used to produce stamping dies and punch holes at multiple angles, requires multiple sets of punching devices, such as horizontal, vertical, and inclined ones, resulting in a complex and compact mechanical structure, limiting chip removal space, and high manufacturing and maintenance costs. Moreover, the processing accuracy requirements are higher for smaller stamping dies, and the hole position may be offset due to die positioning errors or material springback during multi-face punching, affecting the processing accuracy and quality of the stamping die. Summary of the Invention

[0004] To address the aforementioned shortcomings of existing technologies, this invention provides a multi-angle stamping processing equipment for molds with pneumatic linkage perforation. This effectively solves the problems of existing technologies, where traditional stamping processing equipment requires multiple sets of punching devices when producing stamping dies and punching at multiple angles. This results in a complex and compact mechanical structure that limits chip removal space, leading to high manufacturing and maintenance costs. Furthermore, it addresses the issue that smaller stamping dies require higher processing precision, and that multi-faceted punching can cause hole position displacement due to mold positioning errors or material springback, affecting the processing precision and quality of the stamping die.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] This invention provides a multi-angle stamping processing equipment for molds with pneumatic linkage perforation, comprising:

[0007] The press body is equipped with a base at the lower end. The press body consists of a drive cylinder, a press plate and a press platform.

The telescopic end of the telescopic sliding sleeve is fixedly connected to a horizontally installed bevel gear.

[0013] Furthermore, the intermittent rotation assembly includes a secondary pneumatic push rod that is installed through the lower left side of the stamping plate. A pressing plate is installed on the secondary telescopic end of the secondary pneumatic push rod. An L-shaped plate is fixedly sleeved on the upper side of the pressing plate at the secondary telescopic end of the secondary pneumatic push rod. A rectangular through hole is opened at the lower end of the vertical section of the L-shaped plate. A rectangular slide groove is opened at the lower end of the stamping plate corresponding to the position of the rectangular through hole. A wedge-shaped slide plate is slidably connected in the rectangular slide groove by a compression spring.

[0014] Furthermore, the intermittent rotation assembly also includes a support plate connected by a compression spring on the inner wall of the rectangular through hole away from the wedge-shaped slide plate. A semi-circular head insert rod is installed through the middle of the support plate and slides through the L-shaped plate.

An avoidance slide hole is provided at the bottom of the annular cover plate corresponding to the position of the semi-circular head insert rod. The outer wall of the semi-circular head insert rod is movably attached to the inner wall of the spiral groove and the avoidance slide hole.

[0015] Furthermore, the upper end of the stamping platform is symmetrically equipped with arc-shaped support plates at the front and back. The opposite ends of the two arc-shaped support plates are respectively connected to clamping plates by compression springs.

[0016] Furthermore, the angle adjustment section also includes multiple magnets evenly distributed in a circle embedded at the lower end of the stamping plate and the upper end of the mounting plate, and a punch is installed on the lower side of the inner wall of the annular cover plate through an extension plate.

[0017] Furthermore, the upper side of the outer wall of the auxiliary support base has multiple rectangular mounting slots 1 evenly distributed in a circle. The inner wall of the circular mounting slots has rectangular mounting slots 2 corresponding to the positions of the multiple rectangular mounting slots 1. A snap-fit ​​plate is slidably installed in the rectangular mounting slot 2 by a compression spring.

[0019] The technical solution provided by this invention has the following advantages compared with the prior art:

[0020] This invention provides a multi-angle stamping processing device for molds with pneumatic linkage perforation. Simultaneously, a driving cylinder moves the stamping plate downwards while controlling the extension of the primary telescopic end of a secondary pneumatic push rod. This extension extends until the lower end of the pressing plate presses against the sliding plate, causing it to retract into the receiving groove. The sliding plate then moves the rack downwards, meshing with the transmission gears and engaging in transmission. This causes the rotating shaft to rotate intermittently by 120 degrees. The rotating shaft, through two bevel gears, drives the auxiliary support seat to rotate intermittently by 120 degrees. A magnet is used to assist in alignment with the support tray, thus achieving the effect of adjusting the punching angle by intermittently rotating the stamping mold by 120 degrees via the auxiliary support seat.

[0021] By adopting a single-sided sequential punching method, there is no need to configure multiple punching devices, which would lead to complex and compact mechanical structures and high costs. At the same time, it can avoid the problem of hole position displacement caused by mold positioning errors or material springback during multi-sided punching, effectively improving processing accuracy and quality. Moreover, the waste material obtained from punching will fall into the circular cavity of the auxiliary support base, and then fall onto the inner wall of the bottom of the circular mounting groove before being discharged through the discharge hole into the waste collection trough for centralized treatment, thus achieving a convenient chip removal effect.

[0041] The adjustment assembly 64 includes an annular feeding plate rotatably mounted on the lower side of the inner wall of the circular cavity of the auxiliary support base 62. A bevel gear 641 is mounted on the lower end of the annular feeding plate. A bevel gear 641 is vertically arranged on the lower side of the auxiliary support base 62.

An oblong through hole communicating with the receiving groove is opened on the inner wall of the circular mounting groove. The left end of the rotating shaft 642 is slidably connected to the inner wall of the oblong through hole and is mounted on an oblong plate 643.

[0042] The adjusting assembly 64 also includes a grooved wheel and a mating cam mounted on the left end of the waist-shaped plate 643 via a connecting shaft. A connecting plate 644 is mounted on the left end of the grooved wheel. A mounting groove is provided on the lower side of the outer wall of the connecting plate 644. A counterweight lever 645 is slidably connected in the mounting groove via a compression spring. A transmission gear 646 is mounted on the left end of the connecting plate 644.

Multiple magnets 648 are embedded in the lower end of the auxiliary support base 62 and the upper end of the support tray 61 in a circumferentially evenly distributed manner.

[0043] Two circular sliding holes are symmetrically opened on the upper end of the support tray 61. Guide rods 611 are slidably installed in both circular sliding holes. An annular connecting plate 612, which is rotatably connected to the inner wall of the bottom end of the circular mounting groove, is installed at the bottom end of the two guide rods 611. A telescopic sleeve 613 is installed in the middle of the annular connecting plate 612 through multiple connecting rods. The telescopic end of the telescopic sleeve 613 is fixedly connected to the horizontally installed bevel gear 641.

[0044] The intermittent rotation assembly 55 includes a secondary pneumatic push rod 551 that is installed through the lower left side of the stamping plate. A pressing plate 552 is installed on the secondary telescopic end of the secondary pneumatic push rod 551. An L-shaped plate 553 is fixedly sleeved on the upper side of the pressing plate 552 at the secondary telescopic end of the secondary pneumatic push rod 551. A rectangular through hole is opened at the lower end of the vertical section of the L-shaped plate 553. A rectangular slide groove is opened at the lower end of the stamping plate corresponding to the position of the rectangular through hole. A wedge-shaped slide plate 554 is slidably connected in the rectangular slide groove by a compression spring.

[0045] The intermittent rotation assembly 55 also includes a support plate 555 connected by a compression spring on the inner wall of the rectangular through hole away from the wedge-shaped slide plate 554. A semi-circular head insert rod 556 is installed through the middle of the support plate 555 and slides through the L-shaped plate 553. Multiple spiral grooves are evenly distributed in a circle on the outer wall of the mounting plate 52. An avoidance slide hole is provided at the bottom of the annular cover plate 4 corresponding to the position of the semi-circular head insert rod 556. The outer wall of the semi-circular head insert rod 556 is movably attached to the inner wall of the spiral groove and the avoidance slide hole.

[0046] The upper end of the stamping platform is symmetrically equipped with arc-shaped support plates 31. The opposite ends of the two arc-shaped support plates 31 are respectively connected to clamping plates 32 by compression springs. The lower side of the rear arc-shaped support plate 31 is slidably installed with a sliding plate 33. A rectangular punch 34 is installed at the front end of the sliding plate 33.

[0047] The angle adjustment part 5 also includes multiple magnets 51 that are evenly distributed in a circle at the lower end of the stamping plate and the upper end of the mounting plate 52. A punch 54 is installed on the lower side of the inner wall of the annular cover plate 4 through an extension plate.

[0048] The auxiliary support base 62 has multiple rectangular mounting slots 1 evenly distributed around its outer wall. Rectangular mounting slots 2 are also provided on the inner wall of the circular mounting slots, corresponding to the positions of the rectangular mounting slots 1. A snap-fit ​​plate 624 is slidably installed in each rectangular mounting slot 2 via a compression spring. The snap-fit ​​end of the snap-fit ​​plate 624 is movably attached to the inner wall of the corresponding rectangular mounting slot 1. Two circular slots are provided at the lower end of the stamping plate, corresponding to the position of punch 1 53. The upper end of the auxiliary support base 62 and the support tray 61 both have clearance holes 1. The lower end of the auxiliary support base 62 and the support tray 61 both have multiple clearance holes 2 evenly distributed around their respective positions, corresponding to the position of punch 2 54. Multiple rectangular clearance holes are provided on the outer wall, corresponding to the position of the rectangular punch 34.

[0049] The bottom of the base 1 is provided with a waste collection trough, and the upper inner wall of the waste collection trough is provided with a discharge hole that connects to the circular mounting groove. A detachable sealing plate 2 is installed at the bottom of the base 1 corresponding to the position of the waste collection trough.

[0050] In practice:

[0051] First, the upper surface of the auxiliary support base 62 in this application is initially flush with the upper surface of the stamping platform. At this time, multiple snap-fit ​​plates 624 are inserted into the corresponding rectangular mounting slots, and the slide plate 63 initially extends out of the receiving slot. The external loading robot first transports the stamping die that needs to be punched from right to left to the upper position of the circular mounting slot. It should be noted that the bottom diameter of the stamping die is larger than the diameter of the circular opening at the top of the circular mounting slot. The stamping die will squeeze the two clamping plates 32 to make them move away from each other. When the stamping die moves to the upper end of the circular mounting slot, under the action of the compression spring, the two clamping plates 32 will move closer to each other and jointly clamp the stamping die to complete the loading work, and play a role in the alignment and correction of the stamping die.

[0052] Before punching, the drive cylinder is controlled to move the stamping plate downwards. Simultaneously, the first-stage telescopic end of the secondary pneumatic push rod 551 extends, causing the pressing plate 552 to move downwards until its lower end presses against the mating slide plate 63, causing it to retract into the receiving groove. During the downward movement of the mating slide plate 63, it drives the rack 647 downwards, meshing with the transmission gear 646 and engaging in transmission, causing the connecting plate 644 to rotate. The connecting plate 644 then drives the counterweight lever 645 to rotate synchronously. Through the counterweight lever 645, the mating cam, and the grooved wheel, the rotating shaft 642 rotates intermittently by 120 degrees. The rotating shaft 642, through two bevel gears 641, drives the auxiliary support seat 62 to rotate intermittently by 120 degrees, and uses magnet 648 to assistedly align with the bearing tray 61. During this process, the auxiliary support seat 62 will press against multiple... Each snap-fit ​​plate 624 retracts into its corresponding rectangular mounting slot, thereby releasing the auxiliary support seat 62 from the snap-fit. Under the action of the compression spring, the support plate 61 will drive the auxiliary support seat 62 to move upward and insert into the stamping die for support. It should be noted that the telescopic sleeve 613 is equipped with a spiral spring (not shown), which can provide a buffer space for the telescopic sleeve 613 after the auxiliary support seat 62 rotates intermittently by 120 degrees. When the support plate 61 moves upward and both guide rods 611 exit their corresponding circular sliding holes, the telescopic sleeve 613 will drive the two guide rods 611 to rotate intermittently by 120 degrees through the annular connecting plate 612 under the action of the spiral spring. At this time, the upper ends of the two guide rods 611 are movably attached to the lower end surface of the support plate 61, thereby achieving the effect of limiting and supporting the support plate 61.

[0053] It should also be noted that punch 53 is initially located to the right of clearance hole 1. At this time, the upper end of punch 53 is inserted into the corresponding circular groove, and the upper end will movably fit against the lower end face of the stamping plate. The insertion end of the semi-circular head insert 556 is initially movably fitted against the inner wall of the higher end of the corresponding spiral groove. When the first-stage telescopic end of the secondary pneumatic push rod 551 extends, it will drive the L-shaped plate 553 to move downward synchronously. The L-shaped plate 553 will drive the semi-circular head insert 556 to move downward synchronously through the support cross plate 555. Under the combined action of the semi-circular head insert 556 and the spiral groove, it will drive the installation... The mounting plate 52 rotates intermittently by 120 degrees and is aligned with the magnet 51. When the semi-circular head insert 556 continues to move downward to the wedge-shaped surface of the lower end of the wedge-shaped slide plate 554, it will exit the spiral slide groove under the action of the compression spring and continue to slide downward along the inner wall of the clearance hole, thereby achieving the effect of detaching from the mounting plate 52. During this period, the punch 53 will be squeezed and retracted into the stepped slide hole. After the mounting plate 52 rotates intermittently by 120 degrees, the upper end face of the punch 53 will be tightly attached to the lower end face of the stamping plate under the action of the compression spring and aligned with the position of the clearance hole.

[0054] During punching, as the control drive cylinder drives the stamping plate to continue moving downward, the stamping plate will drive the annular cover plate 4 and the mounting plate 52 to move downward until punch one 53 punches the stamping die and inserts into the first clearance hole. At the same time, punch two 54 will also punch the corresponding position of the stamping die and insert into the corresponding clearance hole two. During the downward movement of the annular cover plate 4, it will also squeeze the abutting slide plate 33 to move it to one side of the stamping die. The abutting slide plate 33 will drive the rectangular punch 34 to punch the corresponding position of the side wall of the stamping die and insert into the rectangular clearance hole. The waste in clearance hole one and clearance hole two will fall onto the inner wall of the bottom of the circular mounting groove and be discharged into the waste collection groove through the discharge hole. The waste in the rectangular clearance hole will fall into the circular cavity of the auxiliary support seat 62, and similarly fall onto the inner wall of the bottom of the circular mounting groove and be discharged into the waste collection groove through the discharge hole for centralized processing.

[0055] After the punching work in this direction is completed, the control drive cylinder moves the stamping plate upward to return to its original position. At this time, the secondary pneumatic push rod 551, the annular cover plate 4, and the mounting plate 52 will move upward accordingly. Then, the control of the primary telescopic end of the secondary pneumatic push rod 551 retracts, moving the pressing plate 552 upward to return to its original position. During this process, under the action of the compression spring, the sliding plate 63 extends out of the receiving groove to return to its original position. The sliding plate 63 will move the rack 647 upward and mesh with the transmission gear 646 to drive the connecting plate. When 644 rotates in the reverse direction, the connecting plate 644 will drive the counterweight lever 645 to rotate synchronously in the reverse direction. It should be noted that when the counterweight lever 645 is in the lower position, it is in an extended state under its own weight and the force of the compression spring. When the counterweight lever 645 rotates to the upper position, it will retract under its own weight. At this time, as the sliding plate 63 drives the rack 647 to move upward and return to its original position, the counterweight lever 645 will not insert into the groove on the grooved wheel to drive its reverse rotation. Furthermore... When the first-stage telescopic end of the secondary pneumatic push rod 551 retracts and drives the L-shaped plate 553 to move upward and return to its original position, the insertion end of the semi-circular head insert rod 556 will slide upward along the inner wall of the clearance sliding hole. When the semi-circular head insert rod 556 moves upward to the wedge-shaped surface of the lower end of the wedge-shaped slide plate 554, it will slide towards the mounting plate 52 under the extrusion force and insert into the lower end of the corresponding spiral groove. As the semi-circular head insert rod 556 continues to move upward, the extrusion force on the insertion end of the semi-circular head insert rod 556 will be greater than that on the wedge-shaped slide plate 554. The force of the compression spring on 54 causes the insertion end of the semi-circular head insert 556 to exit the corresponding spiral groove and push the wedge-shaped slide plate 554 back into the rectangular groove. When the semi-circular head insert 556 moves upward to return to its original position and is located at the higher end of the corresponding spiral groove, the insertion end of the semi-circular head insert 556 will be inserted into the inner wall of the higher end of the corresponding spiral groove again. At this time, the wedge-shaped slide plate 554 will move downward to return to its original position under the action of the compression spring, restoring its limiting and blocking effect on the semi-circular head insert 556.

[0056] When adjusting the stamping angle, it should be noted that since the upper end of the outer shell processed by the stamping die only needs to be stamped with one round hole, the above steps of the stamping plate moving downward and the first-level extension and retraction of the second-level pneumatic push rod 551 are repeated. The difference is that after the mounting plate 52 rotates intermittently by 120 degrees, the punch 53 will rotate intermittently by 120 degrees. At this time, the upper end of the punch 53 is inserted into the corresponding round groove, and the lower end will be flush with the lower end surface of the mounting plate 52, thereby achieving the effect of hiding the punch 53 and not participating in this punching work.

[0057] When adjusting the stamping angle again, repeat the steps of moving the stamping plate downwards and the first-stage extension and retraction of the secondary pneumatic push rod 551. The punch 53 will still rotate intermittently by 120 degrees. The upper end of the punch 53 will be inserted into the corresponding circular slot, and the lower end will be flush with the lower surface of the mounting plate 52. It will not participate in this punching operation. The difference is that after all the punching of the sidewalls and bottom of the stamping die is completed, the two guide rods 611 will correspond to the circular sliding holes on the support plate 61, controlling the extension and retraction of the secondary pneumatic push rod 551. The secondary pneumatic push rod 551 will then drive the pressing plate 552 to move downwards again, and the pressing plate 552 will again press against the sliding plate 63. As it moves downwards, it should be noted that whenever the first telescopic end of the second-stage pneumatic push rod 551 extends, the outer wall of the rotating shaft 642 will slide against the inner wall of the upper end of the mating groove. When the second telescopic end extends, under the limiting action of the mating groove, the mating slide plate 63 will drive the rotating shaft 642 to move downwards synchronously. The rotating shaft 642 will drive the bearing tray 61 and the auxiliary support seat 62 to move downwards synchronously until the upper end face of the auxiliary support seat 62 is flush with the upper end face of the stamping platform. During this period, the two guide rods 611 will be inserted into the corresponding circular sliding holes on the bearing tray 61 to return to their original positions. In addition, the multiple snap-fit ​​plates 624 will also be inserted into the corresponding rectangular mounting slots under the action of the compression spring to restore the snap-fit ​​effect.

[0058] When removing the stamping die, after the multi-angle punching work of the stamping die is completed, since the upper surface of the auxiliary support 62 is now flush with the upper surface of the stamping platform, the external material handling robot can remove the stamping die after punching.

[0059] In summary, this application has the following advantages:

[0060] Firstly, this application employs two clamping plates 32. When the external loading robot transports the stamping die requiring punching from right to left to the upper position of the circular mounting groove, the stamping die will squeeze the two clamping plates 32 to move them away from each other. After the stamping die moves to the upper end of the circular mounting groove, under the action of the compression spring, the two clamping plates 32 will move closer to each other and jointly clamp the stamping die to complete the loading work, and also play a role in aligning and correcting the stamping die, avoiding the problem of misalignment of the stamping die leading to the displacement of the punching position.

[0061] Secondly, before punching, while controlling the drive cylinder to move the stamping plate downward, the first-stage telescopic end of the secondary pneumatic push rod 551 is extended until the lower end of the pressing plate 552 presses against the sliding plate 63, causing it to retract into the receiving groove. The sliding plate 63 will drive the rack 647 to move downward and mesh with the transmission gear 646 for transmission, which will drive the rotating shaft 642 to rotate intermittently by 120 degrees. The rotating shaft 642 will drive the auxiliary support seat 62 to rotate intermittently by 120 degrees through two bevel gears 641, and will be assisted in alignment with the support tray 61 through the second magnet 648. During this period, the auxiliary support seat 62 will press multiple snap-fit ​​plates 624 to retract into the corresponding rectangular mounting grooves, thereby achieving the effect of releasing the snap-fit ​​of the auxiliary support seat 62, and the support tray 61 will drive the auxiliary support seat 62 to move upward and insert into the stamping die for limiting support.

[0062] Thirdly, whenever the first-stage telescopic end of the secondary pneumatic push rod 551 extends, it will drive the L-shaped plate 553 to move downward synchronously. The L-shaped plate 553 will drive the semi-circular head insert rod 556 to move downward synchronously through the support plate 555. Under the combined action of the semi-circular head insert rod 556 and the spiral slide groove, the mounting plate 52 will rotate intermittently by 120 degrees, and the magnet 51 will assist in the alignment. During each 120-degree intermittent rotation of the mounting plate 52, the punch 53 will be aligned or staggered with the position of the clearance hole 1 in turn, so that the lower punching end of the punch 53 will extend or retract respectively, thereby achieving the effect of freely controlling the extension and retraction of the punch 53 to participate in the punching work.

[0063] Fourthly, during punching, the stamping plate will drive the annular cover plate 4 and the mounting plate 52 to move downwards until the punch 1 53 punches the stamping die and inserts into the clearance hole 1. At the same time, the punch 2 54 will also punch the corresponding position of the stamping die and insert into the corresponding clearance hole 2. During the downward movement of the annular cover plate 4, it will also squeeze the contact plate 33 to move it to one side of the stamping die. The contact plate 33 will drive the rectangular punch 34 to punch the corresponding position of the side wall of the stamping die and insert into the rectangular clearance hole. The waste in the clearance hole 1 and clearance hole 2 will fall onto the inner wall of the bottom of the circular mounting groove and be discharged into the waste collection groove through the discharge hole. The waste in the rectangular clearance hole will fall into the circular cavity of the auxiliary support 62, and similarly fall onto the inner wall of the bottom of the circular mounting groove and be discharged into the waste collection groove through the discharge hole for centralized processing, thereby achieving the effect of convenient chip removal.

[0064] Fifthly, the control of the drive cylinder moves the stamping plate upward to return to its original position, and controls the retraction of the first-stage telescopic end of the secondary pneumatic push rod 551, moving the pressing plate 552 upward to return to its original position. This, in conjunction with the slide plate 63, moves the rack 647 upward, meshing with the transmission gear 646 and driving the connecting plate 644 in the opposite direction. The connecting plate 644 then drives the counterweight lever 645 to rotate synchronously in the opposite direction. When the counterweight lever 645 rotates to the upper position, it retracts under its own weight, preventing it from inserting into the groove on the grooved wheel and causing it to rotate in the opposite direction. This achieves the effect of intermittently rotating the stamping die 120 degrees via the auxiliary support seat 62 to adjust the punching angle. Using a single-sided sequential punching method eliminates the need for multiple punching devices, thus avoiding the problems of complex and compact mechanical structures and high costs. Furthermore, it avoids the problem of hole position misalignment caused by die positioning errors or material springback during multi-sided punching, effectively improving processing accuracy and quality.

[0065] Advantage six: After all the holes on the side wall and bottom of the stamping die are punched, the secondary telescopic end of the secondary pneumatic push rod 551 is extended, and the pressing plate 552 will press the sliding plate 63 again to move it downward. The sliding plate 63 will drive the rotating shaft 642 to move downward synchronously. The rotating shaft 642 will drive the support plate 61 and the auxiliary support seat 62 to move downward synchronously until the upper surface of the auxiliary support seat 62 is flush with the upper surface of the stamping platform. During this period, the two guide rods 611 will be inserted into the corresponding circular sliding holes on the support plate 61 to return to their original positions. In addition, multiple snap-fit ​​plates 624 will be inserted into the corresponding rectangular mounting slots to restore the snap-fit ​​effect, thereby achieving the effect of the auxiliary support seat 62 automatically retracting into the circular mounting slot without affecting the free removal of the stamping die.
