DETAILED DESCRIPTION

[0040] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0041] Example 1: Reference Figure 1-Figure 3The double-sided aluminum cabinet panel with sound insulation and heat insulation comprises: a plurality of cabinet panels 1 plugged in sequentially. First connecting strips 2 are provided on both sides of the plurality of cabinet panels 1, and the first connecting strips 2 are closely attached to the side edges of the plurality of cabinet panels 1 to increase the connection strength. A plurality of countersunk holes 4 are evenly opened on one side of the first connecting strip 2, and the design of the countersunk holes 4 facilitates the subsequent installation and fixing of bolts.

[0042] Correspondingly, a threaded hole 5 corresponding to the countersunk hole 4 is provided on one side of each cabinet panel 1, that is, the side in contact with the adjacent cabinet panel 1. During installation, multiple cabinet panels 1 are arranged in sequence to ensure that the countersunk hole 4 on the first connecting strip 2 is aligned with the threaded hole 5 on the adjacent cabinet panel 1. Subsequently, a first bolt 6 is inserted into each countersunk hole 4, and one end of the first bolt 6 is screwed into the corresponding threaded hole 5, so that multiple cabinet panels 1 are tightly connected together by threaded connection to form a stable cabinet structure.

[0043] The cabinet panels 1 on both sides of the cabinet panel are additionally provided with second connecting strips 3 at one end. The second connecting strips 3 are fixedly connected to the two first connecting strips 2 by second bolts 7, further strengthening the stability of the cabinet panel edge and preventing loosening or deformation caused by external force.

[0044] The internal structure of each cabinet panel 1 includes a first aluminum plate 8, a second aluminum plate 9 and sound insulation cotton 10. The second aluminum plate 9 is fixedly arranged at the bottom of the first aluminum plate 8, and a receiving cavity is formed between the two. The sound insulation cotton 10 is cleverly placed in this receiving cavity, effectively blocking the propagation of sound and improving the sound insulation performance of the cabinet panel. At the same time, the design of the double-layer aluminum plate, combined with the use of the sound insulation cotton 10, also significantly enhances the heat insulation effect of the cabinet panel.

[0045] In order to further improve the assembly accuracy and stability of the cabinet panel, a positioning component is also provided on the first aluminum plate 8. Specifically, step grooves 11 are processed at both ends of the first aluminum plate 8. Two groups of sockets 14 are provided on these step grooves 11, and each group of sockets 14 corresponds to a positioning point. On one side of the step groove 11, a threaded hole corresponding to the socket 14 is also provided for installing a pin 15. When it is necessary to connect two adjacent first aluminum plates 8, it is only necessary to screw the pin 15 into the threaded hole and insert the end thereof into the corresponding socket 14 to achieve precise positioning and fixation. In addition, an installation groove 12 is also provided on the step groove 11, and the installation groove 12 is filled with a rubber strip 13. These rubber strips 13 play a sealing role when the two adjacent first aluminum plates 8 are in contact, further enhancing the sealing and sound insulation and heat insulation effects of the cabinet panel.

[0046] Example 2: Reference Figure 4-Figure 8, a shearing device for double-sided aluminum cabinet panels with sound insulation and heat insulation, which is used to process the above-mentioned double-sided aluminum cabinet panels with sound insulation and heat insulation, includes a workbench 16, on the top of which a support frame 17 is arranged. An electric push rod 18 is penetrated through the top of the support frame 17, and a mounting plate 29 is fixedly connected to the output end of the electric push rod 18. Two second guide rods 28 are fixedly installed on the top of the mounting plate 29, and these second guide rods 28 are penetrated and slidably arranged on the support frame 17 to ensure the stability of the mounting plate 29 during the lifting process. A cutter 33 is fixedly installed at the bottom of the mounting plate 29 for cutting the first aluminum plate 8. A rectangular hole 44 corresponding to the cutter 33 is opened on the top of the workbench 16, so that the cutter 33 can smoothly penetrate the workbench for cutting.

[0047] In order to realize the stamping of the step groove 11 and the mounting groove 12, the device is further equipped with an upper module 32, which is sleeved on the cutter 33. At the same time, two lower modules 42 are fixedly installed on the top of the workbench 16, respectively located on both sides of the rectangular hole 44. When the upper module 32 is used in conjunction with the two lower modules 42, the first aluminum plate 8 can be stamped to form the required step groove 11 and mounting groove 12.

[0048] In order to avoid the step groove 11 from colliding with the lower module 42 during the conveying process, the device is also provided with a lifting mechanism. The mechanism includes two groups of first sliding rods 26 that are slidably arranged on the top of the workbench 16. A fixing bar 19 is fixedly connected to the top of each group of first sliding rods 26, and a plurality of connecting rollers 21 are rotatably installed between the two fixing bars 19 to support the first aluminum plate 8. The outer wall of the first sliding rod 26 is sleeved with a tension spring 27, and the two ends of the tension spring 27 are respectively fixedly connected to the bottom of the workbench 16 and the outer wall of the first sliding rod 26 to provide a reset force. When the electric push rod 18 drives the mounting plate 29 to descend, the fixing bar 19 will descend accordingly and place the first aluminum plate 8 on the two lower modules 42. Subsequently, under the action of the tension spring 27, the fixing bar 19 will drive the first aluminum plate 8 to rise to avoid conflict with the lower module 42 during the conveying process.

[0049] In addition, an extension platform 35 is fixedly provided at both ends of the upper module 32, and two third sliding rods 36 are slidably provided on the top of the extension platform 35. A pressing plate 38 is fixedly connected to the bottom end of the third sliding rod 36, and the pressing plate 38 corresponds to one end of the fixed bar 19. A second spring 37 is sleeved on the outer wall of the third sliding rod 36, and the two ends of the second spring 37 are respectively fixedly connected to the pressing plate 38 and the extension platform 35 near one side. During the stamping process, the pressing plate 38 will first contact the fixed bar 19 and drive it to move downward to ensure the accuracy and stability of the stamping.

[0050] In order to realize the punching function, the device is also provided with a punching mechanism. The mechanism includes a plurality of punching rods 34 that are slidably arranged on one side of the upper module 32. A sliding ring 39 is slidably arranged in the upper module 32, and the sliding ring 39 is fixedly sleeved on the punching rod 34. The outer wall of the punching rod 34 is sleeved with a third spring 40, and the two ends of the third spring 40 are respectively fixedly connected to the inner wall of one side of the upper module 32 and one side of the sliding ring 39. Both sides of the cutter 33 are provided with a wedge-shaped groove 41 used in conjunction with the punching rod 34. During the cutting process of the cutter 33, the wedge-shaped groove 41 will push the punching rod 34 to extend and punch the first aluminum plate 8. At the same time, a through hole 43 corresponding to the punching rod 34 is also provided on one side of the lower module 42 to ensure that the punching rod 34 can smoothly pass through the lower module 42 for punching.

[0051] Example 3: Reference Figure 4-Figure 8 , improved on the basis of Example 2: In order to ensure that the cutting is performed after the stamping is in place, a plurality of second sliding rods 30 are also slidably arranged on the top of the mounting plate 29. The bottom ends of these second sliding rods 30 are fixedly connected to the upper module 32, and a first spring 31 is sleeved on the outer wall thereof. The two ends of the first spring 31 are respectively fixedly connected to the mounting plate 29 and the upper module 32 on one side close to each other. When the electric push rod 18 pushes the mounting plate 29 down, the upper module 32 will first contact with the first aluminum plate 8 and perform stamping, and after the stamping is in place, the cutter 33 will perform cutting.

[0052] In order to adapt to the first aluminum plates 8 of different widths, at least two fixing seats 22 are fixedly provided on the top of the fixing bar 19. A first guide rod 23 is fixedly installed between the two fixing seats 22 on the same side, and two guide blocks 20 are slidably sleeved on the outer wall of the first guide rod 23. A bidirectional screw 24 is also rotatably provided between the two fixing seats 22, and the two guide blocks 20 are respectively threadedly sleeved on the two threaded sections on the bidirectional screw 24. By rotating the bidirectional screw 24, the distance between the two guide blocks 20 can be adjusted to adapt to the first aluminum plates 8 of different widths. An arc groove 25 corresponding to the connecting roller 21 is also provided at the bottom of the guide block 20 to ensure that the guide block 20 and the connecting roller 21 can fit tightly.

[0053] A method for preparing a sound-insulating and heat-insulating double-sided aluminum cabinet board by using a shearing device for a sound-insulating and heat-insulating double-sided aluminum cabinet board comprises the following steps:

[0054] S1. First, the first aluminum plate 8 is conveyed to the workbench 16 by a conveyor, and the first aluminum plate 8 is placed on the connecting roller 21. Then, the bidirectional screw 24 is rotated to adjust the distance between the two guide blocks 20 until it corresponds to the width of the first aluminum plate 8, and then the first aluminum plate 8 is conveyed in a fixed length.

[0055] S2, then, the electric push rod 18 is started to extend, driving the upper module 32 to move downward, and driving the multiple connecting rollers 21 to move downward, placing the first aluminum plate 8 on the two through holes 43, and continuing to move downward to cooperate with the two through holes 43 to punch the first aluminum plate 8, so that two step grooves 11 and a rubber strip 13 are formed in the middle of the first aluminum plate 8;

[0056] S3, then, the electric push rod 18 is started again to continue to extend, driving the cutter 33 to move downward, cooperating with the rectangular hole 44 to cut the first aluminum plate 8 at the bottom, and the cut waste falls into the collection box below through the rectangular hole 44;

[0057] S4. At the same time, the cutter 33 moves downward to drive the punching rod 34 to extend through the wedge-shaped groove 41, and cooperates with the through hole 43 to punch one side of the step groove 11;

[0058] S5, finally start the electric push rod 18 to reset and move, and continue to start the conveyor to transport the first aluminum plate 8, and continue stamping and cutting.

[0059] In the present application, first, the first aluminum plate 8 is conveyed to the workbench 16 by a conveyor, and the first aluminum plate 8 is located between the connecting roller 21 and the first guide rod 23, and then the bidirectional screw 24 is rotated to adjust the spacing between the two guide blocks 20 until it corresponds to the width of the first aluminum plate 8, and then the first aluminum plate 8 is conveyed at a fixed length;

[0060] Then, the electric push rod 18 is started to extend, driving the mounting plate 29 to move downward. The downward movement of the mounting plate 29 can drive the upper module 32 to move downward through the multiple first springs 31. During the downward movement of the upper module 32, the second spring 37 can drive the pressing plate 38 to move downward. The downward movement of the pressing plate 38 can drive the corresponding fixing bar 19 to move downward. The downward movement of the fixing bar 19 can simultaneously drive the multiple connecting rollers 21 to move downward, place the first aluminum plate 8 on the two through holes 43, and stretch the tension spring 27. The electric push rod 18 is started again to extend to drive the upper module 32 to move downward. The downward movement of the upper module 32 can cooperate with the two through holes 43 to stamp the first aluminum plate 8, so that two step grooves 11 and the rubber strip 13 are formed in the middle of the first aluminum plate 8, and the third sliding rods 36 on both sides are compressed at the same time.

[0061] Secondly, the electric push rod 18 is started again to continue to extend, driving the mounting plate 29 to move downward. The downward movement of the mounting plate 29 can drive the cutter 33 to move downward, cooperate with the rectangular hole 44 to cut the first aluminum plate 8 at the bottom, and compress the first spring 31 at the bottom of the mounting plate 29, so that the cut waste falls into the collection box below through the rectangular hole 44;

[0062] At the same time, the cutter 33 moves downward to drive the punching rod 34 to extend through the wedge-shaped groove 41, and cooperates with the through hole 43 to punch one side of the step groove 11;

[0063] Finally, the electric push rod 18 is started to reset and move. During the retraction of the workbench 16, the mounting plate 29 can be driven to move upward. The upward movement of the mounting plate 29 can drive the cutter 33 to move upward, and at the same time, the first spring 31 is reset. After the first spring 31 is reset, continuing to move upward can drive the extension table 35 to move upward, so that the second spring 37 is reset and moved. After the second spring 37 is reset, the electric push rod 18 is started again to retract, which can drive the pressure plate 38 to move upward, and the fixing bar 19 can be reset and moved under the action of the tension spring 27, driving the first aluminum plate 8 to move upward, so that one end of the first aluminum plate 8 moves to the top of the lower module 42, and the conveyor is started again to transport the first aluminum plate 8, which can push the trimmed first aluminum plate 8 to one side. After it is transported to a suitable length, the electric push rod 18 is started again for stamping and trimming.
