Description

Technical Field

[0002] Aluminum plates, which are rectangular cross-section plates with uniform thickness made of pure aluminum or aluminum alloy materials by pressure processing, often need to be punched on their surfaces during the manufacturing process to improve installation convenience or enhance aesthetics. However, although the punching aluminum plate processing device in the current technology (as shown in the patent with publication number CN207642103U) realizes the punching of multiple rows of through holes on the aluminum plate through the relative rotation of the upper and lower working rollers, its application scope has significant limitations.

[0003] Specifically, the device is mainly suitable for punching thinner aluminum plates, but it is not capable of punching aluminum plates of a certain thickness. The reason is that the cylindrical die design it adopts has a fixed length and is limited by its structural characteristics, making it difficult to extend significantly. When a cylindrical die that is too long is used to punch thick aluminum plates under high-speed rotation, it is not only easy to cause the shape of the punching to be distorted, but it may also cause mechanical interference due to the motion trajectory, affecting the processing accuracy and efficiency. Therefore, the length of the cylindrical die in the device is strictly controlled within a certain range, which limits its ability to process thicker aluminum plates and its overall applicability is relatively limited.

DETAILED DESCRIPTION

[0023] Embodiments of the present application are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present application, and should not be construed as limiting the present application.

[0024] The aluminum plate punching equipment according to an embodiment of the present application is described below with reference to the accompanying drawings.

[0025] like Figure 1-Figure 6 As shown, the aluminum plate punching equipment of the embodiment of the present application includes a supporting frame 10, a U-shaped frame 20, a retractable mechanism 30, a supporting assembly 40, a punching device 50 and a driving device 60.

[0026] The U-shaped frame 20 is arranged in the support frame 10 for lifting and movement, the retractable mechanism 30 is arranged on the support frame 10, and the output end of the retractable mechanism 30 is detachably connected to the U-shaped frame 20, wherein the retractable mechanism 30 is used to drive the U-shaped frame 20 to lift and move. It should be noted that a slide groove (not specifically marked in the figure) is provided on the support frame 10 described in this embodiment, and the U-shaped frame 20 is slidably connected to the slide groove through a slider (not specifically marked in the figure).

[0027] It should be noted that the telescopic mechanism 30 described in this embodiment can be a cylinder, a hydraulic cylinder or an electric telescopic rod. It is understandable that the telescopic mechanism 30 is detachably connected to the U-shaped frame 20, which facilitates the installation and replacement of the telescopic mechanism 30. For example, the telescopic mechanism 30 can be connected to the U-shaped frame 20 by threaded fasteners such as screws, bolts or bolts.

[0028] The support assembly 40 is disposed in the support frame 10 and is located below the U-shaped frame 20, wherein the support assembly 40 is used to support the aluminum plate to be punched. The punching device 50 is disposed on the U-shaped frame 20, and the punching device 50 may include an outer cylinder 51, an inner cylinder 52, a plurality of punching mechanisms 53, a pressing mechanism 54, and a plurality of transmission mechanisms 55.

[0029] Among them, the outer cylinder 51 is rotatably arranged in the U-shaped frame 20 and is located above the support assembly 40, and multiple groups of positioning through holes 501 distributed around are opened on the outer cylinder 51. For example, the multiple groups of positioning through holes 501 can be 12 groups, that is, 12 groups of positioning through holes are distributed around and arranged on the outer cylinder 51, wherein each group of positioning through holes can include 7, 8, 9, 10, 11, 12 positioning through holes arranged side by side at equal distances, etc. The specific number of use can be set according to actual conditions and is not limited here. The inner cylinder 52 is fixedly arranged in the outer cylinder 51, and multiple groups of punching mechanisms 53 are distributed around and are arranged between the outer cylinder 51 and the inner cylinder 52 in a lifting and moving manner, and the multiple groups of punching mechanisms 53 are respectively connected to the corresponding positioning through holes 501 in a sliding manner.

[0030] The pressing mechanism 54 is horizontally and movably arranged in the inner cylinder 52, and the two ends of the pressing mechanism 54 respectively penetrate the two side walls of the U-shaped frame (20). Multiple groups of transmission mechanisms 55 are arranged in the inner cylinder 52 in a surrounding manner, wherein the number of the multiple groups of transmission mechanisms 55 is the same as the number of the multiple groups of positioning through holes 501, that is, 12 groups, and each group of transmission mechanisms 55 can include 3, 4, 5, 6 equidistant and parallel transmission mechanisms 55, etc. The specific number of settings can be selected according to actual conditions and is not limited here, and one end of the transmission mechanism 55 penetrates the inner cylinder 52 and is connected to the corresponding punching mechanism 53, and the other end of the transmission mechanism 55 is close to the pressing mechanism 54.

[0031] The driving device 60 is disposed on the U-shaped frame 20 and is connected to the pressing mechanism 54 and the outer cylinder 51 respectively, wherein the driving device 60 is used to drive the outer cylinder 51 to perform intermittent 30° rotation and drive the pressing mechanism 54 to perform intermittent reciprocating movement.

[0032] It should be noted that the driving device 60 described in this embodiment drives the outer cylinder 51 to intermittently rotate 30° each time, and simultaneously drives the pressing mechanism 54 to reciprocate once.

[0033] Specifically, in order to enhance the aesthetic effect of the aluminum plate, when the aluminum plate needs to be punched, the relevant staff first needs to place the aluminum plate to be punched on the support assembly 40 and place it directly below the outer cylinder 51. Then, the staff controls the retractable mechanism 30 to drive the U-shaped frame 20 to drive the punching device 50 to move up and down, thereby adjusting the height of the outer cylinder 51 in the punching device 50, so that the outer cylinder 51 fits the top surface of the aluminum plate to be punched, so as to be suitable for punching aluminum plates of different thicknesses, effectively improving the applicable range of punching aluminum plates of different thicknesses.

[0034] At this time, the staff controls the driving device 60 to drive the outer cylinder 51 to intermittently rotate 30°, and the rotating outer cylinder 51 drives the aluminum plate to be punched to move a certain distance on the support assembly 40, and at this time a group (a row) of positioning holes 501 on the outer cylinder 51 is located directly above the aluminum plate to be punched. After the outer cylinder 51 rotates 30°, the driving device 60 simultaneously drives the top pressing mechanism 54 to reciprocate once, and when the top pressing mechanism 54 moves toward the transmission mechanism 55, it will apply a top pressing force to a group of transmission mechanisms 55 facing the bottom positioning holes 501, and the group of transmission mechanisms 55 are forced to push the corresponding punching mechanism 53 out of the bottom positioning holes 501 and punch the aluminum plate to be punched.

[0035] When the aluminum plate to be punched has completed a row of punching holes, the pressing mechanism 54 is reset, and the punching mechanism 53 is also reset. At this time, the driving device drives the outer cylinder 51 to rotate 30 degrees again, and pushes the aluminum plate to be punched to move further on the support assembly 40 through the friction force of the rotation, and continues to punch the aluminum plate to be punched, and so on and so forth, until the entire aluminum plate to be punched has multiple rows of equidistant and regular through holes, effectively avoiding distortion of the punching shape. This not only helps to improve the punching accuracy and consistency of the aluminum plate, but also effectively ensures stable and reliable product quality.

[0036] In one embodiment of the present application, Figure 1-Figure 3 As shown, the support assembly 40 may include a support platform 41 , a lower pressure-bearing mold 42 and two sets of conveying rollers 43 , wherein the support platform 41 is fixedly disposed on the bottom wall of the support frame 10 .

[0037] The lower pressure-bearing die 42 is fixedly arranged on the support platform 41 and is located directly below the outer cylinder 51. A row of feeding holes 401 corresponding to the positioning through holes 501 are provided on the lower pressure-bearing die 42. Two groups of conveying rollers 43 are located on both sides of the lower pressure-bearing die 42 and are rotatably arranged on the support platform 41. Each group of conveying rollers 43 may include 4, 5, 6, 7, 8 conveying rollers 43, etc. The specific number of conveying rollers 43 used can be selected according to actual conditions and is not limited here. It should be noted that the height of the conveying rollers 43 described in this embodiment is the same as the height of the lower pressure-bearing die 42.

[0038] It should be noted that the diameter of the feed hole 401 described in this embodiment is the same as the diameter of the positioning through hole 501 .

[0039] It can be understood that when it is necessary to punch the aluminum plate to be punched, the staff can first place the aluminum plate to be punched on a group of conveying rollers 43, and place one end of the aluminum plate to be punched on the lower pressure mold 42. When the outer cylinder 51 moves downward to press the aluminum plate to be punched on the lower pressure mold 42, as the outer cylinder 51 rotates, the aluminum plate to be punched is driven toward another group of conveying rollers 43.

[0040] In one embodiment of the present application, Figure 5 and Figure 6 As shown, the punching mechanism 53 may include a support plate 531 , a plurality of columnar cutting dies 532 and a plurality of first springs 533 .

[0041] The support plate 531 is movably arranged between the outer cylinder 51 and the inner cylinder 52, and a plurality of columnar cutting dies 532 are equidistantly arranged side by side and vertically fixedly arranged on the support plate 531, and the plurality of columnar cutting dies 532 are respectively slidably connected to the corresponding positioning through holes 501. It should be noted that the number of the plurality of columnar cutting dies 532 described in this embodiment is the same as the number of a group (a row) of positioning through holes 501.

[0042] Multiple first springs 533 are respectively mounted on the corresponding columnar cutting dies 532. For example, the multiple first springs 533 can be 3, 4, 5, 6, 7 first springs 533, etc. The specific number of use can be selected according to actual conditions and is not limited here. One end of the first spring 533 is fixedly connected to the support plate 531, and the other end of the first spring 533 is fixedly connected to the inner wall of the outer cylinder 51.

[0043] In one embodiment of the present application, Figure 5 and Figure 6 As shown, the pressing mechanism 54 may include a pressing rod 541 , a first roller 542 , a plurality of driving blocks 543 , a baffle 544 and a second spring 545 .

[0044] The push rod 541 is horizontally and movably arranged in the inner cylinder 52, and the two ends of the push rod 541 respectively penetrate the two side walls of the U-shaped frame 20. It should be noted that the push rod 541 described in this embodiment can be a rectangular push rod 541.

[0045] The first roller 542 is rotatably connected to one end of the push rod 541, and a plurality of driving blocks 543 are equidistantly arranged side by side and detachably arranged on the bottom wall of the push rod 541. The baffle plate 544 is close to the other end of the push rod 541 and is fixedly arranged on the push rod 541, and the baffle plate 544 is movably connected to the inner cylinder 52. The second spring 545 is sleeved on the push rod 541, and one end of the second spring 545 is fixedly connected to the baffle plate 544, and the other end of the second spring 545 is fixedly connected to the side wall of the U-shaped frame 20.

[0046] It should be noted that the multiple driving blocks 543 described in this embodiment are detachably arranged on the bottom wall of the push rod 541, which facilitates the installation and replacement of the driving blocks 543. For example, the driving blocks 543 can be connected to the push rod 541 by means of clamping, threaded fastener connection, etc.

[0047] It is understandable that the staff can apply different top pressures to the transmission rod 551 by replacing the drive blocks 543 of different heights, and then adjust the length of the columnar knife die 532 extending from the outer cylinder 51 to improve the applicability of punching aluminum plates of different thicknesses.

[0048] As a possible situation, in order to avoid repeatedly replacing the driving block 543 to adjust the extension length of the columnar cutting die 532, the height of the driving block 543 can also be set to the highest value, so that the length of the columnar cutting die 532 pushed and extended by the driving block 543 each time is in the longest state, thereby effectively improving the applicability of punching aluminum plates of different thicknesses.

[0049] Further, in one embodiment of the present application, Figure 5 and Figure 6 As shown, the transmission mechanism 55 may include a transmission rod 551 and a second roller 552 , wherein one end of the transmission rod 551 is fixedly connected to the support plate 531 , and the other end of the transmission rod 551 penetrates into the inner cylinder 52 and extends to one side of the driving block 543 .

[0050] The second roller 552 is rotatably connected to the other end of the transmission rod 551 , and the second roller 552 is intermittently abuttingly connected to the corresponding driving block 543 .

[0051] Further, in one embodiment of the present application, Figure 4 As shown, the driving device 60 may include a plurality of driving wheels 61 , a driving mechanism 62 , a first bevel gear 63 , a groove wheel 64 , a transmission shaft 65 , a second bevel gear 66 , a cam plate 67 and a belt transmission mechanism 68 .

[0052] The plurality of driving wheels 61 are distributed in a circular array and are rotatably disposed on the outer cylinder 51 close to the first roller 542. It should be noted that the plurality of driving wheels 61 described in this embodiment may be 12 driving wheels 61, and each driving wheel 61 is disposed in parallel with each group (row) of positioning through holes 501.

[0053] The driving mechanism 62 is disposed on the U-shaped frame 20 , and the output end of the driving mechanism 62 is connected to the first bevel gear 63 and the groove wheel 64 respectively.

[0054] It should be noted that the driving mechanism 62 described in this embodiment may be a driving motor.

[0055] The sheave 64 is matched with a plurality of driving wheels 61, and an inclined partition 601 is provided in the groove of the sheave 64, and guide openings 602 are respectively provided on both sides of the partition 601 on the sheave 64. It should be noted that during the rotation of the sheave 64, the partition 601 also rotates synchronously, and when the partition 601 rotates one circle with the sheave 64, one of the driving wheels 61 in the groove of the sheave 64 moves out from one guide opening 602 under the limiting action of the partition 601, and another driving wheel 61 adjacent thereto enters the groove of the sheave 64 from another guide opening 602, and this process just drives the outer cylinder 51 to rotate 30°.

[0056] The transmission shaft 65 is rotatably disposed on the U-shaped frame 20 . The second bevel gear 66 is connected to one end of the transmission shaft 65 , and the second bevel gear 66 is meshed with the first bevel gear 63 .

[0057] The cam plate 67 is rotatably disposed on the U-shaped frame 20, and the cam plate 67 is abutted against and connected to the first roller 542, and the belt transmission mechanism 68 is respectively connected to the rotating shaft of the cam plate 67 and the other end of the transmission shaft 65. It should be noted that the belt transmission mechanism 68 described in this embodiment may include two pulleys (not specifically marked in the figure) and a belt (not specifically marked in the figure), one of which is connected to the rotating shaft of the cam plate 67, and the other is connected to the other end of the transmission shaft 65, and the belt is sleeved on the two pulleys.

[0058] It should be noted that the initial position of the groove wheel 64 described in this embodiment can be rotated 10-30° from the initial position, and the outer cylinder 51 can be driven by the driving wheel 61 to rotate 30°. When the groove wheel 64 rotates one circle, the outer cylinder 51 remains stationary during this process, and the cam plate 67 rotates one circle and drives the push rod 541 to reciprocate once. That is, when the outer cylinder 51 remains stationary, the cam plate 67 drives the push rod 541 to reciprocate once.

[0059] Specifically, when it is necessary to punch the aluminum plate to be punched placed on the lower pressure die 42, the staff can control the driving mechanism 62 to drive the first bevel gear 63 and the groove wheel 64 to rotate synchronously. The rotating groove wheel 64 first drives the outer cylinder 51 to rotate 30° through the driving wheel 61. At this time, the outer cylinder 51 remains stationary, and a group (a row) of positioning through holes 501 on the outer cylinder 51 is located directly above the blanking hole 401. During the rotation of the outer cylinder 51, the outer cylinder 51 drives the aluminum plate to be punched to move a certain distance by friction.

[0060] At the same time, the first bevel gear 63 drives the transmission shaft 65 to rotate through the second bevel gear 66, and the rotating transmission shaft 65 drives the cam plate 67 to rotate through the belt transmission mechanism 68. After the outer cylinder 51 rotates 30 degrees, the rotating cam plate 67 applies a pressing force to the first roller 542. The first roller 542 is forced to push the pressing rod 541 to drive multiple driving blocks 543 and the baffle 544 to move. The moving baffle 544 compresses the second spring 545, and the moving driving block 543 presses the first roller 542 to move. The second roller 552 in the bottom group of transmission mechanisms 55 applies downward pressure, and the second roller 552 is pressed to push the support plate 531 downward through the transmission rod 551. The moving support plate 531 compresses the first spring 533 and drives multiple columnar cutting dies 532 to extend from the corresponding positioning through holes 501 and punch the aluminum plate to be punched until the columnar cutting dies 532 extend into the corresponding discharge hole 401, thereby completing the punching of the aluminum plate to be punched, and the punched hole-shaped waste is discharged from the discharge hole 401.

[0061] After a row of through holes are punched out of the aluminum plate to be punched, as the cam plate 67 rotates, the pressure rod 541 gradually loses the pressure applied by the cam plate 67, and under the reverse force of the second spring 545, the pressure rod 541 drives the multiple driving blocks 543 to reset, and at the same time, the support plate 531 drives the multiple columnar cutting dies 532 to reset under the reverse force of the first spring 533.

[0062] When the rotating groove wheel 64 drives the outer cylinder 51 to continue to rotate 30° by driving the driving wheel 61, the rotating outer cylinder 51 will continue to drive the aluminum plate to be punched to move, and continue to punch the moving aluminum plate to be punched through the columnar knife die 532. The above steps are repeated repeatedly until the entire aluminum plate to be punched is punched with multiple rows of regular through holes.

[0063] It is understandable that by pressing and extending the columnar die 532 to punch holes in the aluminum plate, the columnar die 532 will not be limited by its length, and the columnar die 532 can punch holes in aluminum plates of different thicknesses by adjusting the height of the outer cylinder 51. Moreover, when the outer cylinder 51 rotates, the shape of the punched hole will not be distorted due to the excessively long columnar die when punching holes in thick aluminum plates.

[0064] In summary, the aluminum plate punching equipment of the embodiment of the present application can not only realize the punching of multiple rows of regular through holes on the aluminum plate, but also effectively improve the applicability of punching holes in aluminum plates of different thicknesses, and effectively avoid distortion and deformation of the punching shape, which not only helps to improve the punching accuracy and consistency of the aluminum plate, but also can effectively ensure the stable and reliable product quality.
