Description

Technical Field

[0001] The invention belongs to the technical field of metal auxiliary processing, and in particular relates to an aluminum foil forming machine with a smoothing structure and a smoothing method thereof. Background Art

[0002] Aluminum foil stamping is to use a mold to apply pressure to the aluminum foil to make the aluminum foil plastically deformed, so as to obtain the desired shape and size. This process is similar to other metal stamping processes, but because the aluminum foil is thinner, the requirements for mold accuracy and stamping parameters are higher. Mechanical punching machines have higher stamping speeds and pressures, which are suitable for large-scale and efficient aluminum foil stamping production. Its working principle is to convert the rotational motion of the motor into the up and down reciprocating motion of the slider through mechanical structures such as crankshafts and connecting rods, driving the mold to stamp the aluminum foil; hydraulic punching machines can provide more stable pressure, and the pressure can be precisely adjusted as needed, which is very beneficial for stamping aluminum foil products with complex shapes and strict pressure requirements, such as some aluminum foil packaging materials with fine patterns.

[0003] During the stamping process of aluminum foil, the aluminum foil is loose on the lower mold, which will cause wrinkles on the aluminum foil. Direct stamping will affect the quality of aluminum foil forming. Excessive tension will cause the aluminum foil to tear, affecting processing. Therefore, we designed an aluminum foil forming machine with a smoothing structure and a smoothing method. Before each stamping, the aluminum foil to be stamped is properly smoothed to avoid loose wrinkles and excessive tension and tearing of the aluminum foil, thereby ensuring the quality of aluminum foil stamping.

[0006] Preferably, the front and rear sides of the square hole are fixedly connected to limit rings, and the front and rear sides of the inner cavity of the fixed shell are provided with annular grooves for the limit rings to rotate.

[0007] Preferably, a cavity is provided at the top and the bottom of the inner cavity of the fixing shell, four cross screws are provided through the arc-shaped spring piece, and the arc-shaped spring piece is installed in the inner cavity of the cavity by the four cross screws.

[0008] Preferably, a rotatable rotating circular plate is provided at the bottom of the front side of the stamping machine, a sliding pin 2 is fixedly connected to the front side of the rotating circular plate, and a rectangular through hole 2 for sliding the sliding pin 2 is provided in the middle of the front side of the strip-shaped long rod.

[0009] Preferably, the front side of the stamping machine is rotatably connected to a cylinder via a rotating shaft, the output end of the cylinder is fixedly connected to a connecting seat, the surface of the rotating circular plate is fixedly connected to a connecting arm, and the connecting arm is rotatably connected to the inner cavity of the connecting seat via a rotating shaft.

[0010] Preferably, both ends of the front side of the stamping and forming machine are fixedly connected with guide seats, the inner cavity of the guide seats is slidably connected with guide rods, and the bottom of the guide rods is fixedly connected to the strip-shaped long rod.

[0011] Preferably, a bearing seat is installed inside the stamping machine by bolts, the inner cavity of the bearing seat is rotatably connected to a rotating rod, and the front end of the rotating rod is fixedly connected to the rotating circular plate.

[0013] Preferably, the pressing roller is close to the guide roller and is located above the aluminum foil, and the surfaces of the pressing roller and the guide roller are smooth.

[0014] An aluminum foil forming machine with a smoothing structure, the aluminum foil smoothing method steps are as follows:

[0015] Step 1: The aluminum foil passes through the top of the upper platform of the stamping machine by unwinding, and the stamping aluminum foil waste is reeled and recycled by the reeling machine. During the stamping process of the aluminum foil, that is, before the hydraulic cylinder on the stamping machine drives the upper mold to move to the lower mold, the cylinder shortens and pulls the connecting arm and the rotating circular plate through the connecting seat to rotate with the rotating rod as the axis. The sliding pin 2 on the rotating circular plate slides in the inner cavity of the rectangular through hole 2 on the strip long rod, which drives the strip long rod to move upward. The strip long rod moves upward stably under the guidance of the guide rod and the guide seat. The upward movement of the strip long rod drives the sliding pin 1 to slide in the inner cavity of the rectangular through hole 1. The two sliding pins 1 cause the two swing arm rods to rotate in opposite directions with the shaft rod as the axis, so that the pressing roller at the end of the swing arm rod presses on the aluminum foil;

[0016] Step 2: During the movement of the pressure roller, it contacts the aluminum foil and rotates, which drives the rotating pin, the square block and the screw rod to rotate. The square block drives the rotating disk to rotate in the inner cavity of the fixed shell due to the square hole. The arc-shaped spring piece in the inner cavity of the fixed shell is deformed during the rotation of the rotating disk, and detaches from and enters the inner cavity of the arc-shaped slot on the surface of the rotating disk, which limits the smooth rotation of the rotating disk, so that the rotating disk has a certain damping effect. When not subjected to force, it will not rotate by itself, so that the pressure roller can stably press down the aluminum foil, so that the aluminum foil is tightened and smoothed under the action of the two guide rollers, so that the aluminum foil on the top of the lower mold is in a tensioned state, and is not in an over-tensioned state, so that the aluminum foil on the top of the lower mold is tightened and smoothed;

[0017] Step 3: The hydraulic cylinder on the stamping machine drives the upper mold to move downward, and the stamping is performed in cooperation with the lower mold to ensure the molding quality. The upper mold moves upward to remove the stamped product. Then the cylinder extends to move the long bar downward. The long bar makes the two swing arms rotate towards each other with the shaft as the axis, so that the clamping roller cancels the contact with the aluminum foil. Then the winder winds up the stamping waste until the new aluminum foil moves to the bottom of the lower mold.

[0018] The beneficial effects of the present invention are:

[0019] 1. The present invention drives two swing arm rods to rotate in opposite directions with the shaft rod as the axis through a driving assembly, so that the pressing roller is pressed on the aluminum foil. The pressing roller and the swing arm rod are limited by the damping of the damping installation assembly, which ensures that the pressing roller does not rotate too fast to affect the tensioning effect, and the pressing roller does not stop rotating to cause excessive tension and tearing. The purpose of properly tightening and smoothing the aluminum foil to be punched before each punching is achieved to avoid loose wrinkles and excessive tension and tearing of the aluminum foil, thereby ensuring the quality of the aluminum foil punching.

[0020] 2. The present invention uses the annular groove and the limiting ring in combination. When the rotating disk rotates in the inner cavity of the fixed shell, the limiting ring will rotate in the inner cavity of the annular groove, providing limitation and guidance for the rotation of the rotating disk, avoiding eccentric rotation, and improving the stability and reliability of the rotation of the rotating disk.

[0021] 3. The present invention uses a guide seat and a guide rod in coordination. During the movement of the strip-shaped long rod, the guide rod will be driven to slide in the inner cavity of the guide seat, providing guidance for the movement of the strip-shaped long rod, ensuring that the strip-shaped long rod can only move vertically up and down, thereby improving the stability of the movement of the strip-shaped long rod.

[0037] An aluminum foil forming machine with a smoothing structure, the aluminum foil smoothing method steps are as follows:

[0038] Step 1: The aluminum foil passes through the top of the upper platform 2 of the stamping machine 1 by unwinding, and the stamping aluminum foil waste is reeled and recycled by the reeling machine. During the stamping process, that is, before the hydraulic cylinder on the stamping machine 1 drives the upper mold 4 to move to the lower mold 3, the cylinder 107 shortens and pulls the connecting arm 109 and the rotating circular plate 104 through the connecting seat 108 to rotate around the rotating rod 1013. The sliding pin 105 on the rotating circular plate 104 is on the long bar. The inner cavity of the second rectangular through hole 106 on 101 slides, which drives the long strip rod 101 to move upward, and the long strip rod 101 moves upward stably under the guidance of the guide rod 1011 and the guide seat 1010. The upward movement of the long strip rod 101 drives the sliding pin 103 to slide in the inner cavity of the first rectangular through hole 102, and the two sliding pins 103 make the two swing arm rods 7 rotate in opposite directions with the shaft rod 6 as the axis, so that the pressing roller 8 at the end of the swing arm rod 7 presses on the aluminum foil;

[0039] Step 2: During the movement of the pressing roller 8, it contacts with the aluminum foil, and the pressing roller 8 rotates, and the pressing roller 8 drives the rotating pin 91, the square block 92 and the screw rod 93 to rotate. The square block 92 drives the rotating disk 96 to rotate in the inner cavity of the fixed shell 95 due to the square hole 97. The arc-shaped spring piece 99 in the inner cavity of the fixed shell 95 is deformed during the rotation of the rotating disk 96, and is separated from and enters the inner cavity of the arc-shaped slot 98 on the surface of the rotating disk 96, which limits the smooth rotation of the rotating disk 96, so that the rotating disk 96 has a certain damping effect. When not subjected to force, it will not rotate by itself, so that the pressing roller 8 can stably press down the aluminum foil, so that the aluminum foil is tightened and smoothed under the action of the two guide rollers 5, so that the aluminum foil on the top of the lower mold 3 is in a tensioned state, and is not in an over-tensioned state, so that the aluminum foil on the top of the lower mold 3 is tightened and smoothed;

[0040] Step 3: The hydraulic cylinder on the stamping machine 1 works to drive the upper mold 4 to move downward, and the stamping and molding are carried out in cooperation with the lower mold 3 to ensure the molding quality. The upper mold 4 moves upward to remove the stamped product, and then the cylinder 107 extends to make the long strip rod 101 move downward. The long strip rod 101 makes the two swing arm rods 7 rotate towards each other with the shaft rod 6 as the axis, so that the clamping roller 8 cancels the contact with the aluminum foil, and then the winder winds up the stamping waste until the new aluminum foil moves to the bottom of the lower mold 3.

[0041] To sum up: the aluminum foil forming machine with a smoothing structure drives the two swing arm rods 7 to rotate in opposite directions with the shaft rod 6 as the axis through the driving component 10, so that the clamping roller 8 is pressed on the aluminum foil, and the clamping roller 8 and the swing arm rod 7 are limited by the damping mounting component 9 to ensure that the clamping roller 8 does not rotate too fast to affect the tensioning effect, and the clamping roller 8 does not stop rotating and cause excessive tension and tearing. Therefore, before each stamping, the aluminum foil to be stamped can be properly tightened and smoothed to avoid loose wrinkles and excessive tension and tearing of the aluminum foil, thereby ensuring the quality of aluminum foil stamping.

[0042] The technical features disclosed above are not limited to the disclosed combinations with other features. Those skilled in the art may also make other combinations between the technical features according to the purpose of the invention to achieve the purpose of the invention.

The stamped aluminum foil waste is reeled and recycled by the reeling machine. During the stamping and forming process of the aluminum foil, that is, before the hydraulic cylinder on the stamping and forming machine (1) drives the upper mold (4) to move toward the lower mold (3), the cylinder (107) shortens and pulls the connecting arm (109) and the rotating circular plate (104) through the connecting seat (108) to rotate around the rotating rod (1013). The sliding pin 2 (105) on the rotating circular plate (104) is on the long strip rod (1 01) slides in the inner cavity of the upper rectangular through hole 2 (106), which drives the strip long rod (101) to move upward, and the strip long rod (101) moves upward stably under the guidance of the guide rod (1011) and the guide seat (1010). The upward movement of the strip long rod (101) drives the sliding pin 1 (103) to slide in the inner cavity of the rectangular through hole 1 (102), and the two sliding pins 1 (103) cause the two swing arm rods (7) to rotate in opposite directions with the shaft rod (6) as the axis, so that the pressure roller (8) at the end of the swing arm rod (7) is pressed on the aluminum foil; Step 2: During the movement of the pressing roller (8), the pressing roller (8) contacts the aluminum foil and rotates. The pressing roller (8) drives the rotating pin (91), the square block (92) and the screw rod (93) to rotate. The square block (92) drives the rotating disk (96) to rotate in the inner cavity of the fixed shell (95) due to the square hole (97). The arc-shaped spring piece (99) in the inner cavity of the fixed shell (95) is deformed during the rotation of the rotating disk (96) and detaches from and enters the inner cavity of the arc-shaped slot (98) on the surface of the rotating disk (96), thereby limiting the smooth rotation of the rotating disk (96).

The upper die (4) moves upward to remove the stamped product. Then the cylinder (107) extends, so that the long bar (101) moves downward. The long bar (101) causes the two swing arm rods (7) to rotate towards each other with the shaft (6) as the axis, so that the pressure roller (8) cancels the contact with the aluminum foil. Then the winding machine winds up the stamping waste until the new aluminum foil moves to the bottom of the lower die (3).
