Description

Technical Field

[0001] This invention belongs to the field of heat sink processing technology, and particularly relates to a transformer heat sink forming and processing device and method. Background Technology

[0002] A 220-5V transformer is a switching transformer. Its operating frequency is adjusted to tens of kHz, allowing it to be made very small. This is the technology commonly used in most mobile phone chargers on the market today. A heat sink is a device for dissipating heat from easily heated electronic components in an electrical appliance. It is usually made of aluminum alloy, brass, or bronze and can be in the form of plates, sheets, or multiple sheets. Among these materials, aluminum alloy is relatively soft, making it easier to process. Therefore, the heat sink in a mobile phone charger is usually formed by bending a rectangular plate. After forming, the heat sink includes a cover plate and side plates on both sides of the cover plate. By placing the heat sink inside the charger casing, heat can be dissipated from the switching transformer inside the mobile phone charger, ensuring that the switching transformer is within a suitable operating temperature range.

[0003] Because the heat sink inside a mobile phone charger is small, existing bending equipment cannot be used to bend it precisely. Furthermore, the two side plates of the heat sink are bent at different points on the rectangular plate, requiring two positioning operations to complete the forming process. Additionally, the bending points differ for different heat sink sizes. Therefore, a forming device is needed that can quickly position and bend any bending point on the rectangular plate, while ensuring the stability of rectangular plates of different models after positioning to prevent displacement of the side plates formed by bending. Summary of the Invention

[0004] This invention provides a transformer heat sink forming and processing apparatus and method to solve the problems in the prior art.

[0005] The present invention adopts the following technical solution: a transformer heat sink forming and processing device, including a bracket, a support plate and a bending knife. The support plate is horizontally installed on the upper end of the bracket. A vertically extending vertical plate is provided on the right side of the support plate. The bending knife is arranged parallel to the vertical plate and is located on the right side of the vertical plate. The bending knife is longitudinally slidably disposed above the support plate. A first strip block and a second strip block are also provided above the support plate. Both the first strip block and the second strip block extend along the front-back direction of the support plate. The first strip block is located to the right of the second strip block and directly above the vertical plate. The first strip block and the second strip block are at the same height. A distance adjustment mechanism for adjusting the distance between the second strip block and the first strip block is provided at the left end of the support plate. A driving mechanism is also provided above the support plate. The driving mechanism is used to adjust the height of the first strip block and the second strip block and can independently drive the bending knife to rise and fall.

[0006] Furthermore, the adjusting mechanism includes a rectangular block and a rotating shaft. Side plates are installed at both the front and rear ends of the support plate. The rotating shaft is located between the two side plates, and its two ends are rotatably mounted on the two side plates respectively. The rectangular block is located at the upper end of the support plate. A vertical block is installed on the left side of the support plate. Two first guide rods are arranged laterally on the left side of the rectangular block. Two first guide holes are provided on the vertical block. The two first guide rods extend to the left and are slidably disposed in the two first guide holes respectively. The second strip block is slidably disposed on the right side of the rectangular block in the vertical direction. A linkage component is provided between the rotating shaft and the rectangular block. The linkage component can drive the rectangular block to slide left and right on the support plate when the rotating shaft rotates.

[0007] Furthermore, the linkage assembly includes a first link and a second link. The rotating shaft passes through the side plate located in front of the support plate. A knob is also installed in front of the rotating shaft. A first strip groove extending in the left-right direction is also provided on the side plate in front of the support plate. A round rod is provided in front of the rectangular block. The round rod is slidably disposed in the first strip groove. One end of the first link is hinged to the rotating shaft. The other end of the first link is hinged to one end of the second link. The other end of the second link is hinged to the round rod.

[0008] Furthermore, each first guide rod is fitted with a first spring, and both first springs are located between the vertical block and the rectangular block.

[0009] Furthermore, the rectangular block has two first sliding grooves longitudinally arranged on its right side, and the second strip block has two first sliders arranged on its left side, with the two first sliders slidably disposed in the two first sliding grooves respectively.

[0010] Furthermore, the driving mechanism includes a top plate, a support plate, a drive rod, a linear drive assembly, and a rotary drive assembly. The support plate is horizontally disposed between the first strip block and the second strip block, with the bottom of the support plate located above the bottom of the first strip block. The first strip block is fixedly installed on the right side of the support plate, and the second strip block is slidably disposed on the left side of the support plate in the left-right direction. A horizontal plate extends horizontally to the left from the top of the bending blade. The top plate is horizontally installed at the top of the two side plates. The horizontal plate and the support plate are both slidably disposed between the top plate and the support plate in the vertical direction. The horizontal plate is located between the support plate and the support plate. A first bearing seat is fixedly installed on the support plate, and the drive rod is rotatably disposed on the first bearing seat. An clearance hole is provided on the top plate, through which the drive rod passes to the top of the top plate. The lower end of the drive rod is configured as a threaded rod. A threaded hole is provided on the horizontal plate for threaded connection with the threaded rod. The linear drive assembly is disposed on the top plate for driving the drive rod to rise and fall, and the rotary drive assembly is disposed on the top plate for driving the drive rod to rotate.

[0011] Furthermore, the right side of the second strip block is provided with multiple horizontally extending sliding rods, and the left side of the tray is provided with multiple sliding holes extending in the left and right directions, with the multiple sliding rods slidably disposed in the multiple sliding holes respectively.

[0012] Furthermore, the pallet has two vertically arranged second guide holes, the horizontal plate has two vertically arranged third guide holes, and the top plate and the support plate have two longitudinally arranged second guide rods. The two second guide holes are slidably engaged with the two second guide rods, and the two third guide holes are slidably engaged with the two second guide rods.

[0013] Furthermore, the linear drive assembly includes a linear driver, a first bracket, and a second bearing housing. The first bracket is disposed on a top plate, the linear driver is longitudinally mounted on the first bracket, the top of the drive rod is mounted on the second bearing housing, and the output shaft of the linear driver is fixedly connected to the second bearing housing.

[0014] The rotary drive assembly includes a second bracket, a rotary driver, a first gear, a second gear, and an annular plate. The annular plate is mounted on a top plate and coaxially arranged with the drive rod. An annular protrusion coaxially arranged on the upper end of the annular plate is provided. An annular groove coaxially arranged on the bottom of the second gear is provided. The annular protrusion is rotatably disposed within the annular groove. Two strip-shaped blocks are provided on the inner wall of the second gear. Two second strip-shaped grooves are longitudinally arranged on the outer wall of the upper end of the drive rod. The two strip-shaped blocks are slidably disposed within the two second strip-shaped grooves respectively. The second bracket is mounted on the top plate. The rotary driver is mounted on the second bracket. The first gear meshes with the second gear. The first gear is fixedly sleeved on the output shaft of the rotary driver.

[0015] A processing method for a transformer heat sink forming and processing device includes the following steps:

[0016] S1: The operator turns the knob counterclockwise until the round rod is moved to the left end of the first groove, and the second strip block reaches the left limit.

[0017] S2: The worker holds the knob steady, then takes an unprocessed heat sink and places it horizontally under the first and second strip blocks, and pushes the heat sink to press it against the right side of the rectangular block;

[0018] S3: The linear drive operates, and the first strip block, the second strip block, and the bending blade descend synchronously until the first and second strip blocks press against the upper end of the heat sink. Then the operator can release the knob.

[0019] S4: The rotary driver operates, the positions of the first and second strip blocks remain unchanged, the bending blade continues to descend, and the bending blade drives the heat sink to bend downward to form one of the side plates of the heat sink;

[0020] S5: After the rotary driver and linear driver are reset in sequence, the first spring drives the rectangular block to move to the right, while the round rod moves to the right side of the first strip groove, and the second strip block reaches the right limit.

[0021] S6: The staff continues to push the heat sink against the right side of the rectangular block, and the rotary driver and linear driver run in sequence again, thereby bending the heat sink downwards through the bending knife to form another side plate of the heat sink;

[0022] S7: After the rotary driver and linear driver are reset in sequence, the heat sink that has been processed and shaped can be removed by the staff.

[0023] The above-described at least one technical solution adopted in the embodiments of the present invention can achieve the following beneficial effects:

[0024] Firstly, this invention allows for adjustment of the distance between the first and second strip blocks through the setting of the distance adjustment component. By having the operator change the position of the rectangular plate on the support plate, the left end of the rectangular plate is positioned below the second strip block, while the bent portion of the rectangular plate is positioned below the first strip block. This allows the rectangular plate to be bent to form a heat sink. The change in the distance between the first and second strip blocks, combined with the driving mechanism that lowers the first and second strip blocks, enables the heat sink forming device to fix heat sinks of various sizes and specifications in appropriate positions. Furthermore, by setting a driving mechanism to separately lower the bending blade, the forming process of heat sinks of various models and specifications can be completed.

[0025] Secondly, this invention achieves left-right positioning of the rectangular plate by pushing it against the right end of the rectangular block, making operation more convenient for workers. By rotating the knob and pushing the rectangular plate against the rectangular block, any bending position on the rectangular plate can be positioned between the bending blade and the vertical plate, facilitating bending processing at any position on the rectangular plate. In addition, by adjusting the distance between the first and second rectangular blocks, various types of rectangular plates can be bent to form different types of heat sinks. At the same time, the second rectangular block is always pressed against the left end of the rectangular plate, ensuring the stability of the rectangular plate, while the first rectangular block is always pressed against the bending position of the rectangular plate, thus avoiding the inability to guarantee the bending position of the rectangular plate during bending.

[0026] Thirdly, this invention uses a linear actuator to drive the drive rod downwards. The drive rod slides downwards along the two strip blocks on the second gear under the action of the two second strip grooves, thereby achieving synchronous descent of the first strip block, the second strip block, and the bending knife. Since the second gear rotates with the annular protrusion through the annular groove, the rotary actuator drives the first gear to rotate, and the first gear drives the second gear to rotate. Thus, under the limiting action of the strip blocks on the second gear, the drive rod can rotate between the first bearing seat and the second bearing seat. This allows the horizontal plate to continue to descend through the threaded hole, while the first and second strip blocks remain stationary. The descent of the horizontal plate will cause the bending knife to descend separately to perform bending and forming processing on the rectangular plate. Attached Figure Description

Detailed Implementation

[0040] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of this invention, and not all of them. Based on the embodiments of this invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0041] The technical solutions provided by the various embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0042] Reference Figures 1 to 10 As shown, this embodiment of the invention provides a transformer heat sink forming and processing device, including a bracket 1, a support plate 2, and a bending knife 3. The support plate 2 is horizontally installed on the upper end of the bracket 1. A vertically extending vertical plate 21 is provided on the right side of the support plate 2. The bending knife 3 is arranged parallel to the vertical plate 21 and is located on the right side of the vertical plate 21. The bending knife 3 is longitudinally slidably disposed above the support plate 2. A first strip block 4 and a second strip block 5 are also provided above the support plate 2. All 5 extend along the front-back direction of the support plate 2. The first strip block 4 is located to the right of the second strip block 5. The first strip block 4 is located directly above the vertical plate 21. The first strip block 4 and the second strip block 5 are at the same height. An adjustment mechanism 6 is provided at the left end of the support plate 2 for adjusting the distance between the second strip block 5 and the first strip block 4. A driving mechanism 7 is also provided above the support plate 2. The driving mechanism 7 is used to adjust the height of the first strip block 4 and the second strip block 5 and can drive the bending knife 3 to rise and fall independently.

[0043] The heat sink 8 is formed by bending a rectangular plate. The heat sink 8 includes a cover plate 81 and side plates 82 located on both sides of the cover plate 81. During the processing of the heat sink 8, the worker first places the rectangular plate on the support plate 2. Then, the distance between the second strip block 5 and the first strip block 4 is adjusted using the distance adjustment mechanism 6 to its maximum value. Next, the left end of the rectangular plate is pushed directly below the second strip block 5. Then, the first strip block 4 and the second strip block 5 are lowered together by the drive mechanism 7 to press and fix the rectangular plate. Then, the bending blade 3 is lowered separately by the drive mechanism 7. Since the bending blade 3 is located on the right side of the vertical plate 21, the bending blade 3 can bend the rectangular plate at a certain angle, thus forming one of the side plates 82 of the heat sink 8. In the same way, the distance between the second strip block 5 and the first strip block 4 is further adjusted by the distance adjustment mechanism 6. Then, the worker... The left end of the rectangular plate is pushed further down to directly below the second strip block 5. Then, the operation of the drive mechanism 7 can be used to bend another part of the rectangular plate, thereby forming another side plate 82 of the heat sink 8. This completes the forming process of the heat sink 8. The distance between the first strip block 4 and the second strip block 5 can be adjusted by setting the distance adjustment component. By changing the position of the rectangular plate on the support plate 2, the left end of the rectangular plate is located below the second strip block 5, and the bent part on the rectangular plate is located below the first strip block 4. This allows the rectangular plate to be bent to form the heat sink 8. The change in the distance between the first strip block 4 and the second strip block 5, combined with the drive mechanism 7 driving the first strip block 4 and the second strip block 5 to descend, allows the heat sink 8 forming device to fix heat sinks 8 of various sizes and specifications in appropriate positions. Then, by setting the drive mechanism 7 to drive the bending knife 3 to descend, the forming process of the heat sink 8 can be completed.

[0044] Specifically, the adjusting mechanism 6 includes a rectangular block 61 and a rotating shaft 62. Side plates 63 are installed at both the front and rear ends of the support plate 2. The rotating shaft 62 is located between the two side plates 63, and the two ends of the rotating shaft 62 are rotatably mounted on the two side plates 63 respectively. The rectangular block 61 is located at the upper end of the support plate 2. A vertical block 64 is installed on the left side of the support plate 2. Two first guide rods 611 are arranged laterally on the left side of the rectangular block 61. Two first guide holes 641 are provided on the vertical block 64. The two first guide rods 611 extend to the left and are slidably mounted in the two first guide holes 641 respectively. The second strip block 5 is slidably mounted on the right side of the rectangular block 61 in the vertical direction. A linkage component 65 is provided between the rotating shaft 62 and the rectangular block 61. The linkage component 65 can drive the rectangular block 61 to slide left and right on the support plate 2 when the rotating shaft 62 rotates.

[0045] By rotating the rotating shaft 62, the rectangular block 61 can be moved left and right on the support plate 2 under the action of the linkage component 65. Since the second strip block 5 is slidably set on the right side of the rectangular block 61 in the vertical direction, the movement of the support plate 2 can drive the second strip block 5 to move with it, thereby realizing the adjustment of the distance between the first strip block 4 and the second strip block 5.

[0046] Specifically, the linkage component 65 includes a first link 651 and a second link 652. The rotating shaft 62 passes through the side plate 63 located in front of the support plate 2. A knob 621 is also installed in front of the rotating shaft 62. A first strip groove 631 extending in the left and right direction is also provided on the side plate 63 in front of the support plate 2. A round rod 612 is provided in front of the rectangular block 61. The round rod 612 is slidably disposed in the first strip groove 631. One end of the first link 651 is hinged to the rotating shaft 62. The other end of the first link 651 is hinged to one end of the second link 652. The other end of the second link 652 is hinged to the round rod 612.

[0047] Each first guide rod 611 is fitted with a first spring 66, and the two first springs 66 are located between the vertical block 64 and the rectangular block 61.

[0048] A knob 621 is provided on the rotating shaft 62. By rotating the knob 621, the operator can change the distance between the first rectangular block 61 and the second rectangular block 61. During processing, the operator can position the rectangular plate in the left-right direction by pushing it against the right end of the rectangular block 61, making operation more convenient. By rotating the knob 621 and pushing the rectangular plate against the rectangular block 61, any bending position on the rectangular plate can be positioned between the bending blade 3 and the vertical plate 21, facilitating bending processing of any position on the rectangular plate by the bending blade 3. Furthermore, by adjusting the distance between the first and second rectangular blocks 61 using the knob 621, various types of rectangular plates can be bent to form different types of heat sinks 8. Under the action of spring 66, the second rectangular block 61 is in the right limit position by default when there is no external force. When the operator rotates the knob 621 counterclockwise, the round rod 612 slides to the left in the first slot 631 under the drive of the first connecting rod 651 and the second connecting rod 652, so that the distance between the second rectangular block 61 and the first rectangular block 61 gradually increases. When the distance between the second rectangular block 61 and the first rectangular block 61 reaches a suitable value, the operator stops rotating the knob 621 to ensure the distance between the first rectangular block 61 and the second rectangular block 61. At the same time, the second rectangular block 61 can always be pressed against the left end of the rectangular plate to ensure the stability of the rectangular plate, while the first rectangular block 61 always remains pressed against the bending position of the rectangular plate, thereby avoiding the rectangular plate from being unable to maintain the bending position when bending.

[0049] Specifically, the rectangular block 61 has two first sliding grooves 613 arranged longitudinally on the right side, and the second strip block 5 has two first sliders 51 arranged on the left side, with the two first sliders 51 slidably disposed in the two first sliding grooves 613 respectively.

[0050] By sliding the two first sliders 51 into the two first grooves 613 respectively, the technical effect of the second strip block 5 sliding vertically to the right of the rectangular block 61 is achieved.

[0051] Specifically, the driving mechanism 7 includes a top plate 71, a support plate 72, a driving rod 73, a linear driving assembly 74, and a rotary driving assembly 75. The support plate 72 is horizontally disposed between the first strip block 4 and the second strip block 5. The bottom of the support plate 72 is located above the bottom of the first strip block 4. The first strip block 4 is fixedly installed on the right side of the support plate 72. The second strip block 5 is slidably disposed on the left side of the support plate 72 in the left-right direction. A horizontal plate 31 extends horizontally to the left from the top of the bending blade 3. The top plate 71 is horizontally installed at the top of the two side plates 63. The horizontal plate 31 and the support plate 72 are both slidably disposed vertically on the top plate 71 and the support plate. Between the support plate 2 and the support plate 72, the horizontal plate 31 is located between the support plate 2 and the support plate 72. A first bearing seat 76 is fixedly installed on the support plate 72. The drive rod 73 is rotatably mounted on the first bearing seat 76. A clearance hole 711 is provided on the top plate 71. The drive rod 73 passes through the clearance hole 711 to the top of the top plate 71. The lower end of the drive rod 73 is provided as a threaded rod 731. A threaded hole 311 is provided on the horizontal plate 31 for threaded connection with the threaded rod 731. The linear drive assembly 74 is provided on the top plate 71 to drive the drive rod 73 to rise and fall. The rotary drive assembly 75 is provided on the top plate 71 to drive the drive rod 73 to rotate.

[0052] The second strip block 5 has a plurality of horizontally extending sliding rods 52 on its right side, and the support plate 72 has a plurality of sliding holes 721 extending in the left and right directions on its left side. The plurality of sliding rods 52 are respectively slidably disposed in the plurality of sliding holes 721.

[0053] The distance between the second strip block 5 and the first strip block 4 can be changed by rotating knob 621. The first strip block 4 is fixedly installed on the right side of the support plate 72. The second strip block 5 is slidably disposed in multiple sliding holes 721 on the support plate 72 via multiple sliding rods 52, thereby ensuring that the second strip block 5 and the first strip block 4 are always at the same height. Since the horizontal plate 31 is threadedly connected to the threaded rod 731 through the threaded hole 311, when the linear drive assembly 74 drives the drive rod 73 to rise and fall, the horizontal plate 31 and the support plate 72 will rise and fall together. The first strip block 4, the second strip block 5, and the bending blade 3 are raised and lowered synchronously. When the first strip block 4 and the second strip block 5 descend together and press against the rectangular plate, the drive rod 73 is rotated by the rotation drive assembly 75. The drive rod 73 is rotatably mounted on the first bearing seat 76, so the rotation of the drive rod 73 will drive the horizontal plate 31 to move downward, thereby achieving the technical effect of driving the bending blade 3 to descend independently. The stability of the first strip block 4 and the first strip block 5 on the rectangular plate, as well as the independent descent of the bending blade 3, can realize the bending and forming of the rectangular plate.

[0054] Specifically, the support plate 72 is vertically provided with two second guide holes 722, the horizontal plate 31 is vertically provided with two third guide holes 312, and the top plate 71 and the support plate 2 are longitudinally provided with two second guide rods 77. The two second guide holes 722 are slidably engaged with the two second guide rods 77 respectively, and the two third guide holes 312 are slidably engaged with the two second guide rods 77 respectively.

[0055] Specifically, the linear drive assembly 74 includes a linear driver 741, a first bracket 742, and a second bearing seat 743. The first bracket 742 is disposed on the top plate 71, the linear driver 741 is longitudinally mounted on the first bracket 742, the second bearing seat 743 is mounted on the top of the drive rod 73, and the output shaft of the linear driver 741 is fixedly connected to the second bearing seat 743.

[0056] The rotary drive assembly 75 includes a second bracket 751, a rotary driver 752, a first gear 753, a second gear 754, and an annular plate 757. The annular plate 757 is mounted on a top plate 71 and coaxially arranged with the drive rod 73. An annular protrusion 758 coaxially arranged is provided at the upper end of the annular plate 757. An annular groove 755 coaxially arranged is provided at the bottom of the second gear 754. The annular protrusion 758 is rotatably disposed in the annular groove 755. Two strip blocks 756 are provided on the inner wall of the second gear 754. Two second strip grooves 732 are longitudinally arranged on the outer wall of the upper end of the drive rod 73. The two strip blocks 756 are slidably disposed in the two second strip grooves 732 respectively. The second bracket 751 is disposed on the top plate 71. The rotary driver 752 is mounted on the second bracket 751. The first gear 753 meshes with the second gear 754. The first gear 753 is fixedly sleeved on the output shaft of the rotary driver 752.

[0057] Two second springs 78 are fitted onto each of the two second guide rods 77. Each second spring 78 is located between the support plate 72 and the support plate 2. Two second guide holes 722 are vertically provided on the support plate 72, and two third guide holes 312 are vertically provided on the horizontal plate 31. This allows the support plate 72 and the horizontal plate 31 to slide vertically on the second guide rods 77. When the linear actuator 741 operates and drives the drive rod 73 to descend, the drive rod 73 will slide downward along the two strip blocks 756 on the second gear 754 under the action of the two second strip grooves 732, thereby realizing the bending of the first strip block 4, the second strip block 5, and the bending. The synchronous descent of the blade 3, coupled with the rotational engagement of the second gear 754 with the annular groove 755 and the annular protrusion 758, causes the first gear 753 to rotate via the operation of the rotary driver 752. The first gear 753 then drives the second gear 754 to rotate. Under the limiting action of the strip block 756 on the second gear 754, the drive rod 73 can rotate between the first bearing seat 76 and the second bearing seat 743. This allows the horizontal plate 31 to continue descending through the threaded hole 311, while the first strip block 4 and the second strip block 5 remain stationary. The descent of the horizontal plate 31 will cause the bending blade 3 to descend independently, thus performing bending and forming processing on the rectangular plate.

[0058] A processing method for a transformer heat sink forming and processing device includes the following steps:

[0059] S1: The operator rotates the knob 621 counterclockwise until the round rod 612 is moved to the left end of the first strip groove 631, and the second strip block 5 reaches the left limit.

[0060] S2: The worker holds the knob 621 steady, then takes an unprocessed heat sink 8 and places it horizontally under the first strip block 4 and the second strip block 5, and pushes the heat sink 8 to press it against the right side of the rectangular block 61.

[0061] S3: When the linear actuator 741 is running, the first strip block 4, the second strip block 5 and the bending blade 3 descend synchronously until the first strip block 4 and the second strip block 5 press against the upper end of the heat sink 8, and then the operator can release the knob 621.

[0062] S4: The rotary driver 752 is running, the positions of the first strip block 4 and the second strip block 5 remain unchanged, the bending knife 3 continues to descend, and the bending knife 3 drives the heat sink 8 to bend downward to form one of the side plates 82 of the heat sink 8;

[0063] S5: After the rotary driver 752 and the linear driver 741 are reset in sequence, the first spring 66 drives the rectangular block 61 to move to the right, while the round rod 612 moves to the right side of the first strip groove 631, and the second strip block 5 reaches the right limit.

[0064] S6: The staff continues to push the heat sink 8 and place it against the right side of the rectangular block 61. The rotary driver 752 and the linear driver 741 run in sequence again, thereby bending the heat sink 8 downward through the bending knife 3 to form another side plate 82 of the heat sink 8.

[0065] S7: After the rotary driver 752 and the linear driver 741 are reset in sequence, the heat sink 8 after processing can be removed by the staff.
