Description

Technical Field

[0001] This invention relates to the field of aluminum frame side hole forming technology, and specifically to an aluminum frame side hole forming tooling. Background Technology

[0002] Aluminum frames, as the name suggests, are frames made of aluminum alloy. Originally used for decorating paintings, these frames have come to be used to wrap around appliances such as refrigerators, televisions, and flat panel lights, making them look more aesthetically pleasing and giving them a metallic feel.

[0003] The existing aluminum frame manufacturing process involves first placing an aluminum strip onto a punching machine, then positioning it, punching holes in the designated areas, removing it after punching, and then transporting it to a bending machine for bending. Once the bending is complete, the aluminum frame production is finished.

[0004] Because the current aluminum frame production process mostly relies on manual loading and unloading, and the loading process also requires workers to position and fix the aluminum plates on the punching machine, this not only increases the labor force but also reduces production efficiency.

[0005] In summary, there is a need for a tooling for forming side holes in aluminum frames that can improve production efficiency. Summary of the Invention

[0041] Example 3

[0042] like Figures 1-4 As shown, based on the above embodiments, this embodiment further provides the following:

The second folding assembly 7 also includes a fourth pneumatic rod 78 and a fifth pneumatic rod 79. The fourth pneumatic rod 78 and the fifth pneumatic rod 79 are fixedly connected to the lower end face of the worktable 1.

A second lifting plate 712 is fixedly connected to the output shaft end of the fifth pneumatic rod 79. A second bending wheel 713 is installed on the upper end face of the second lifting plate 712.

[0044] The bending of the sheet metal is achieved through the cooperation of the first bending plate 75, the second bending plate 77, the first bending wheel 711, and the second bending wheel 713 in the second folding assembly 7, so that the sheet metal forms a complete frame shape.

[0045] Working principle and usage process of this invention:

[0046] In use:

[0047] Material Picking: First, place the sheet material to be processed into the inner cavity of the feeding rack 3. After placement, activate the picking pneumatic rod 41 in the picking assembly. When the picking pneumatic rod 41 begins to retract, it will drive the pusher plate 42, the second damping rod 43, and the triangular block 44 to move towards the sheet material to be processed. As the triangular block 44 moves, since one end of the triangular block 44 is lower than the sheet material, it will be squeezed downwards by the sheet material when it reaches the sheet material. As the triangular block 44 moves downwards, it will squeeze the second damping rod 43, thereby compressing the external spring of the second damping rod 43. When the pusher plate 42 carries the triangular block 44 over the sheet material and into the inner cavity of the feeding rack 3, the material will be pushed into the inner cavity of the feeding rack 3. When the other end of the plate is reached, the triangular block 44 will be reset under the action of the second damping rod 43. When the triangular block 44 is reset, one side of the triangular block 44 is just located on one side of the plate. At the same time, the material picking pneumatic rod 41 starts to work in the opposite direction. When the material picking pneumatic rod 41 works in the opposite direction, it will drive the pusher plate 42, the second damping rod 43, and the triangular block 44 to move in the opposite direction. As the triangular block 44 moves, the plate in the inner cavity of the feeding rack 3 will be pushed down (only one plate can be pushed down at a time, because the opening at the bottom of the feeding rack 3 can only accommodate the thickness of one plate). When the plate is moved to the bottom of the punching assembly 2 by the pusher plate 42, the material picking pneumatic rod 41 will stop working.

[0048] Punching and positioning: At this time, the pneumatic punching rod 22 moves downward, which in turn moves the mounting bracket 23 downward. As the mounting bracket 23 moves downward, it moves the punching rod 24, extension block 26, first damping rod 27, pressure foot 28, connecting rod 58, and second inclined block 59 downward as a whole. As the second inclined block 59 moves downward, it begins to compress the first inclined block 57. The first inclined block 57 drives the I-shaped block 53 to slide within the inclined groove 52. As the I-shaped block 53 moves, it begins to compress... The third damping rod 54 is pressed. Since the third damping rod 54 is fitted with a spring, the external spring of the third damping rod 54 is compressed. As the I-shaped block 53 slides in the inclined groove 52, the I-shaped block 53 will drive the fourth damping rod 55 and the L-shaped positioning block 56 to move closer to both ends of the plate. As the L-shaped positioning block 56 moves closer, the plate is positioned on the worktable 1 by the cooperation of the push plate 42. This prevents the plate from being misaligned during the later punching process, which could cause the punching to deviate.

[0049] When the sheet metal is pressed and positioned by the L-shaped positioning blocks 56 on both sides, the punching pneumatic rod 22 will drive the mounting frame 23 to continue moving downward. As the mounting frame 23 moves downward, the presser foot 28 will first contact the upper surface of the sheet metal. After contact, the sheet metal can be fixed on the worktable 1 by the presser foot in conjunction with the first damping rod 27. After fixing, the punching rod 24 will start punching the sheet metal. After punching is completed, the punching pneumatic rod 22 will be retracted. When the punching pneumatic rod 22 is retracted, the positioning and punching are completed.

[0050] Bending and forming: When the punching pneumatic rod 22 is retracted, the material-retrieving pneumatic rod 41 is activated. The material-retrieving pneumatic rod 41 pushes the sheet metal from the lower part of the punching assembly 2 to one side of the limiting assembly 8 through the pusher plate 42, so that the sheet metal is located under the second folding assembly 7. After the punched sheet metal moves below the limiting assembly 8, the material-retrieving pneumatic rod 41 begins to retract. During the retraction, the next material retrieval and punching will begin. When the material-retrieving pneumatic rod 41 retracts, the first pneumatic rod 63 is activated. The pneumatic rod 63 will start to push the folding plate 64, which will rotate 90 degrees around one end. Since the punched plate is located between the second folding assembly 7 and the worktable 1, when the folding plate 64 rotates towards the second folding assembly 7, it will begin to bend the punched plate for the first time, so that the plate forms an L-shape. After the folding plate 64 completes the first fold, it will be reset under the action of the first pneumatic rod 63. When the first pneumatic rod 63 is reset, the first fold is completed.

[0051] During the second folding, the second pneumatic rod 72 is activated. When the second pneumatic rod 72 starts working, it moves the first auxiliary plate 74 and the first bending plate 75 to one side. As the first bending plate 75 moves to one side, it moves off the sheet metal, leaving only the second bending plate 77 on top of the sheet metal. After the first bending plate 75 retracts from the top of the sheet metal, the fifth pneumatic rod 79 is activated. The fifth pneumatic rod 79 then moves the second lifting plate 712 and the second bending wheel 713 upwards. As the second bending wheel 713 moves upwards, in conjunction with the second bending plate 77, the two ends of the sheet metal are folded together. After bending the sheet metal at 90 degrees, the fifth pneumatic rod 79 retracts, while the third pneumatic rod 73 extends and retracts, and the second pneumatic rod 72 retracts. This causes the second bending plate 77 to be removed from the top of the sheet metal, leaving the first bending plate 75 on top. Once the first bending plate 75 is on top, the fourth pneumatic rod 78 is activated, driving the first lifting plate 710 and the first bending wheel 711 to move upwards. With the cooperation of the first bending wheel 711 and the first bending plate 75, the middle of the sheet metal is bent, forming a rectangular frame and completing the overall processing.

[0052] In summary, the above description demonstrates the automated process of material handling, positioning, punching, and bending to produce individual sheet materials.
