Description

Technical Field

[0001] This invention relates to the field of stamping die technology, and in particular to a high-efficiency stamping die. Background Technology

[0002] Existing zipper springs require stamping with a stamping die. A pressure processing method is used to apply pressure to the spring using a stamping plate installed at the end of the piston rod of a hydraulic cylinder, causing it to undergo plastic deformation, thereby obtaining the desired spring.

[0003] After stamping is completed, the stamped shrapnel needs to be removed manually, which poses certain safety hazards. The large range of motion also makes the removal process slow, thus affecting the efficiency of shrapnel production. Summary of the Invention

[0008] The mounting slot is equipped with a drive assembly, which includes a rotating rod that is horizontally rotatably mounted in the mounting slot, three gears fixedly sleeved on the rotating rod, and a second rack rod. One end of the two first rack rods passes through two through holes and is respectively meshed with two gears located on the rotating rod. A third mounting plate is fixedly mounted on the surface of the stamping plate. The second rack rod is vertically fixedly mounted on the lower surface of the third mounting plate and meshes with the gear located in the middle of the rotating rod.

[0009] As a preferred embodiment, the first pressing component includes a rectangular sleeve fixedly fitted onto the first spring rod, a first abutting ball embedded in the surface of the rectangular sleeve, and a second abutting ball embedded in the groove wall. The surface of the second mounting plate is provided with a locking component for locking the first spring rod.

[0010] As a preferred embodiment, the locking component includes a second spring rod fixedly mounted on the surface of the second mounting plate and a first triangular block fixedly mounted on one end of the second spring rod. The inclined surface of the first triangular block is arranged face-to-face with the inclined surface of the push block, and the surface of the push block is provided with a locking opening.

[0011] As a preferred embodiment, a first trapezoidal plate is fixedly installed on the surface of the first triangular block, and a second trapezoidal plate is fixedly installed on the groove wall by a third spring rod, with the inclined surfaces of the first trapezoidal plate and the second trapezoidal plate facing each other.

[0012] As a preferred embodiment, the stamping groove wall has two mounting grooves, a fourth spring rod is horizontally fixedly installed in the mounting groove, a rectangular plate is fixedly sleeved on the fourth spring rod, an installation rod is rotatably installed on the surface of the rectangular plate, an L-shaped positioning plate is fixedly sleeved on the installation rod, and a torsion spring is sleeved on the installation rod, with the two ends of the torsion spring being fixedly connected to the surfaces of the rectangular plate and the positioning plate, respectively.

[0013] As a preferred embodiment, the bottom wall of the mounting groove has an installation opening, a fifth spring rod is vertically fixedly installed in the installation opening, a second triangular block is fixedly installed at the top of the fifth spring rod, a triangular groove is opened on the lower surface of the rectangular plate, the surface of the second triangular block abuts against the side wall of the rectangular plate, the fourth spring rod is controlled to retract by a transmission component, and the fifth spring rod is controlled to retract by a second pressing component.

[0014] As a preferred embodiment, the transmission component includes a connecting rod fixedly mounted on the surface of the positioning plate, a first ball fixedly mounted on one end of the connecting rod, and a second ball fixedly mounted on the wall of the stamping groove.

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] When the stamping work is finished, as the stamping plate moves upward, the two push blocks will push out the forming spring in the stamping groove, eliminating the safety hazard of picking up the spring by hand and improving the efficiency of spring demolding.

[0019] After the two push blocks push the spring sheet out, they will move down into the two slides until the demolding work is carried out again, at which point they will be removed from the two slides. This prevents the two push blocks exposed outside the slides from affecting the subsequent placement of the spring sheet, and ensures that the spring sheet stamping preparation work can be carried out stably.

[0020] Two positioning plates can correct the position of the spring sheet located in the stamping groove before stamping, so as to avoid the spring sheet and the stamping plate being misaligned during stamping, thus ensuring the quality of spring sheet stamping.

[0021] When the two positioning plates rotate under the pressure of the stamping plate, the two fourth spring rods will retract together and be fixed, so the two positioning plates will not come into contact with the stamping plate. Therefore, when the stamping plate moves up and resets, its surface will not cause wear on the surface of the two positioning plates, thus improving the service life of the positioning plates.

Detailed Implementation

[0033] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0034] Reference Figure 1-10 A high-efficiency stamping die includes a platform 1, a stamping groove 2 is provided on the upper surface of the platform 1, a hydraulic cylinder 3 is fixedly installed on the upper surface of the platform 1 by a support plate, and a stamping plate 4 is fixedly installed at the bottom end of the piston rod of the hydraulic cylinder 3.

[0035] Two sliding grooves 5 are formed on the bottom wall of the stamping groove 2. An installation groove 6 is formed on the upper surface of the platform 1. The groove wall of the sliding groove 5 has a through opening that communicates with the installation groove 6. A first rack rod 7 is slidably arranged in the sliding groove 5. A first mounting plate and an L-shaped second mounting plate are fixedly installed on the left and right side walls of the first rack rod 7, respectively. A first spring rod 8 is fixedly installed on the upper surface of the first mounting plate. A trapezoidal push block 9 is fixedly installed at the top of the first spring rod 8. The first spring rod 8 is controlled to retract by a first pressing component. The first pressing component includes a rectangular sleeve 13 fixedly sleeved on the first spring rod 8, a first abutment ball 14 embedded in the surface of the rectangular sleeve 13, and an embedded... The second ball 15 on the wall of the slide 5 and the surface of the second mounting plate are provided with a locking component for locking the first spring rod 8. The locking component includes a second spring rod 16 fixedly mounted on the surface of the second mounting plate and a first triangular block 17 fixedly mounted on one end of the second spring rod 16. The inclined surface of the first triangular block 17 is arranged face to face with the inclined surface of the push block 9. The surface of the push block 9 is provided with a locking opening 18. A first trapezoidal plate 19 is fixedly mounted on the surface of the first triangular block 17. A second trapezoidal plate 20 is fixedly mounted on the wall of the slide 5 through a third spring rod 35. The inclined surface of the first trapezoidal plate 19 is arranged face to face with the inclined surface of the second trapezoidal plate 20.

[0036] The mounting slot 6 is equipped with a drive assembly, which includes a rotating rod 10 that is horizontally rotatably mounted in the mounting slot 6, three gears 11 that are fixedly sleeved on the rotating rod 10, and a second rack rod 12. One end of each of the two first rack rods 7 passes through two through holes and meshes with the two gears 11 located on the rotating rod 10 respectively. A third mounting plate is fixedly mounted on the surface of the stamping plate 4. The second rack rod 12 is vertically fixedly mounted on the lower surface of the third mounting plate and meshes with the gear 11 located in the middle of the rotating rod 10.

[0037] When the hydraulic cylinder 3 moves the stamping plate 4 upwards and resets, the gear 11, which is engaged with the second rack 12 and fixedly sleeved in the middle of the rotating rod 10, will rotate the rotating rod 10. Consequently, the two gears 11, respectively fixedly sleeved at both ends of the rotating rod 10, will also rotate. During this rotation, the two first racks 7, which are engaged with the two gears 11, will move the two push blocks 9. During this movement, the spring pieces located in the stamping groove 2 will be pushed out without manual removal. When the two push blocks 9 move to their furthest distance, the first spring rod 8 will retract under the pressure of the first abutment ball 14 and the second abutment ball 15. The push block 9 will then move into the sliding groove 5. During this retraction, the inclined surface of the push block 9 will slide into contact with the inclined surface of the first triangular block 17. Under the pressure of the inclined surface, the second spring rod 16 will retract until the inclined surface of the first triangular block 17 no longer contacts the inclined surface of the push block 9. The first spring rod 16 will quickly move the first triangular block 17 back to its original position and extend into the locking port 18 to form a lock. At this time, the first spring rod 8 is locked. Then, the spring piece to be stamped is placed into the stamping groove 2. When the hydraulic cylinder 3 moves the stamping plate 4 downward, the two push blocks 9 will move in the two slides 5 towards the support plate. When they move to the maximum distance, the inclined surfaces of the two first trapezoidal plates 19 will abut against the inclined surfaces of the two second trapezoidal plates 20 respectively. Under the action of the inclined surfaces, the second spring rod 16 will retract again. When the first triangular block 17 moves out of the locking port 18, the first spring rod 8 will quickly move the push block 9 out of the slide 5. The push block 9 will then abut against the side wall of the spring piece in the stamping groove 2 again. When the hydraulic cylinder 3 moves the stamping plate 4 upward, the demolding work is carried out to avoid the two push blocks 9 exposed outside the slide 5 from affecting the subsequent placement of the spring piece, and to ensure that the spring piece stamping preparation work can be carried out stably.

[0038] The stamping groove 2 has two mounting grooves on its wall. A fourth spring rod 21 is horizontally fixedly installed in the mounting groove. A rectangular plate 22 is fixedly sleeved on the fourth spring rod 21. An installation rod 23 is rotatably installed on the surface of the rectangular plate 22. An L-shaped positioning plate 24 is fixedly sleeved on the installation rod 23. A torsion spring 25 is sleeved on the installation rod 23. The two ends of the torsion spring 25 are fixedly connected to the surfaces of the rectangular plate 22 and the positioning plate 24, respectively.

[0039] In the initial state, the bottom surfaces of the two positioning plates 24 are horizontal with the bottom of the stamping groove 2. As long as the spring is placed between the two positioning plates 24, the two positioning plates 24 can correct the position of the spring located in the stamping groove 2 before stamping, so as to avoid the spring and the stamping plate 4 not corresponding during stamping, thus ensuring the quality of the spring stamping.

[0040] An installation opening is provided on the bottom wall of the mounting groove. A fifth spring rod 26 is vertically fixedly installed in the installation opening. A second triangular block 27 is fixedly installed on the top of the fifth spring rod 26. A triangular groove 28 is provided on the lower surface of the rectangular plate 22. The surface of the second triangular block 27 abuts against the side wall of the rectangular plate 22. The fourth spring rod 21 is controlled to retract through a transmission component. The second pressing component includes an L-shaped connecting plate fixedly sleeved on the fifth spring rod 26, a first pressing block 31 fixedly installed on the surface of the connecting plate, a mounting plate 32 fixedly sleeved on the third spring rod 35, and a second pressing block 33 fixedly installed on the surface of the mounting plate 32. The inclined surfaces of the second pressing block 33 and the first pressing block 31 are arranged face to face. The fifth spring rod 26 is controlled to retract through the second pressing component. The transmission component includes a connecting rod fixedly installed on the surface of the positioning plate 24, a first ball 29 fixedly installed on one end of the connecting rod, and a second ball 30 fixedly installed on the wall of the stamping groove 2.

[0041] Initially, the two fourth spring rods 21 are not in a retracted state. When the stamping plate 4 moves down, its lower surface abuts against the two positioning plates 24, pushing the two positioning plates 24 to rotate relative to each other around the two mounting rods 23. During the rotation, the fourth spring rods 21 retract under the pressure of the first ball 29 and the second ball 30. During the retraction, the inclined surface of the triangular groove 28 slides into contact with the inclined surface of the second triangular block 27. Under the pressure of the inclined surface, the fifth spring rod 26 retracts, and when the rectangular plate 22 moves with the fourth spring rod... When the spring rod 21 retracts and its lower surface no longer contacts the second triangular block 27, the fifth spring rod 26 will quickly move the second triangular block 27 upwards. At this time, the second triangular block 27 will block the fourth spring rod 21 from resetting. The two positioning plates 24 will no longer contact the surface of the stamping plate 4, and will quickly rotate and reset under the action of the torsion spring 25. When the stamping plate 4 moves upwards and resets, its surface will no longer cause wear on the surface of the two positioning plates 24. The original situation where both upward and downward movement of the stamping plate 4 would cause wear on the surface of the two positioning plates 24 has changed to only causing wear when the stamping plate 4 moves downwards. The movement of the spring plate 24 causes wear on its surface, thus improving its service life. When a new spring is placed, the distance between the two spring plates 24 increases compared to the initial state because both fourth spring rods 21 are in a retracted state. This facilitates placement of the spring without needing to align it before placing it between the two spring plates 24. Then, as the stamping plate 4 moves downwards, the inclined surfaces of the two first trapezoidal plates 19 abut against the inclined surfaces of the two second trapezoidal plates 20, causing the third spring rod 35 to retract. When retracting, the two mounting plates 32 will each bring two second abutments 33 to press against the two first abutments 31. The first abutments 31, under the pressure, will bring the fifth spring rod 26 to retract until the second triangular block 27 no longer abuts against the surface of the rectangular plate 22. Then, the fourth spring rod 21 will quickly bring the positioning plate 24 back to its original position. During the retraction process, the two positioning plates 24 will correct the position of the spring piece located in the stamping groove 2. After correction, the stamping plate 4 will press against the two positioning plates 24 again to rotate relative to each other, and the two fourth spring rods 21 will be in the retracted state again.

[0042] Magnets 34 are fixedly installed on one end of the fourth spring rod 21 and on the wall of the mounting slot. The magnetic poles of the two magnets 34 are opposite on the side that are close to each other. When the stamping plate 4 moves down and presses against the rotating positioning plate 24, the magnetic force between the two magnets 34 can offset part of the pushing force on the fourth spring rod 21, thereby preventing the fourth spring rod 21 from contracting due to the downward pressing force of the stamping plate 4. The fourth spring rod 21 will only contract when the positioning plate 24 rotates to the point where the first ball 29 and the second ball 30 abut against each other. Moreover, when the second triangular block 27 no longer blocks the fourth spring rod 21 from resetting, the magnetic force between the two magnets 34 can also accelerate the resetting process of the fourth spring rod 21.

[0043] In this invention, when the hydraulic cylinder 3 moves the stamping plate 4 upwards and resets, the gear 11, which is meshed with the second rack 12 and fixedly sleeved in the middle of the rotating rod 10, will rotate the rotating rod 10. Consequently, the two gears 11, respectively fixedly sleeved at both ends of the rotating rod 10, will also rotate together. During this rotation, the two first racks 7, which are meshed with the two gears 11, will move the two push blocks 9. During this movement, the spring pieces located in the stamping groove 2 will be pushed out without manual removal. When the two push blocks 9 move to their furthest distance, the first spring rod 8 will retract and lock under the action of the first pressing component. Push blocks 9 will then move into the slide groove 5 to prevent the two push blocks 9 exposed outside the slide groove 5 from affecting the subsequent placement of the spring sheet, ensuring that the spring sheet stamping preparation work can be carried out stably. Then, the spring sheet to be stamped is placed into the stamping groove 2. When the hydraulic cylinder 3 moves the stamping plate 4 downward, the two push blocks 9 will move towards the support plate in the two slide grooves 5. When they move to the maximum distance, the lock on the first spring rod 8 is released, and the first spring rod 8 will quickly move the push blocks 9 out of the slide groove 5. The push blocks 9 will then abut against the side wall of the spring sheet located in the stamping groove 2 again. When the hydraulic cylinder 3 moves the stamping plate 4 upward, the demolding work will be carried out.
