[0002] Aluminum electrolytic capacitors are capacitors made of an aluminum cylinder as the negative electrode, filled with liquid electrolyte, and a curved aluminum strip inserted as the positive electrode. When producing the aluminum shell of the capacitor, a cover plate needs to be installed on the port of the aluminum shell. Before installing the cover plate, the port of the cylindrical aluminum shell needs to be turned over.

[0003] When flanging a cylindrical aluminum shell with the existing semi-automatic stamping and flanging, the operator first places multiple aluminum shells in corresponding positions. After the multiple aluminum shells are placed, the hydraulic cylinder is controlled to drive the flanging punch to move downward to perform flanging stamping on the aluminum shell ports. After the stamping is completed, the multiple aluminum shells need to be manually removed one by one, and this process is repeated. Since multiple aluminum shells need to be manually removed one by one during this process, the overall flanging efficiency is low. Therefore, the present application provides a stamping and flanging device for capacitor aluminum shell production and processing to meet the needs. Utility Model Content

DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] Example: Reference Figure 1 The stamping and flanging device for the production and processing of capacitor aluminum shells shown in the figure includes a plurality of flanging punches 3 arranged circumferentially at the output end of a first hydraulic cylinder 2, wherein the first hydraulic cylinder 2 is installed on a machine table 1, and also includes a blanking unit 6, which can simultaneously blank a plurality of capacitor aluminum shells after flanging is completed.

[0022] The unloading unit 6 controls the unloading of multiple capacitor aluminum shells after flanging to be performed simultaneously, thereby shortening the unloading time and improving the flanging efficiency.

[0023] As a preferred implementation in this embodiment, Figure 1-3As shown, the unloading unit 6 includes a plurality of first support members 65 and second support members 66 that are circumferentially and oppositely arranged, a gap is provided between the corresponding first support members 65 and second support members 66, the accommodating cavity enclosed by the first support members 65 and second support members 66 is used to place the capacitor aluminum shell, the plurality of second support members 66 are fixedly connected to the machine table 1, the side ends of the plurality of first support members 65 are fixed with slide plates 64, and the slide plates 64 are slidably arranged on the machine table 1, the machine table 1 is provided with a plurality of unloading openings 67, and the plurality of unloading openings 67 are arranged on the corresponding movement paths of the first support members 65, a movable rod 63 is rotatably provided at the bottom of the slide plate 64, and the lower end of the movable rod 63 passes through the corresponding unloading opening 67 and is rotatably connected to the mounting ring 62, the mounting ring 62 is fixedly installed at the output end of the second hydraulic cylinder 61, the second hydraulic cylinder 61 is fixed on the receiving box 4 with an opening at the upper end, and the receiving box 4 is installed at the bottom of the machine table 1.

[0024] When in use, the capacitor aluminum shell is placed in the accommodation cavity surrounded by the first support member 65 and the second support member 66. Figure 3 As shown, the first support member 65 and the second support member 66 support and limit the capacitor aluminum shell, and at this time a gap is set between the first support member 65 and the second support member 66. After the capacitor aluminum shell is stamped, the second hydraulic cylinder 61 is controlled to drive the movable rod 63 to move downward, so that the multiple movable rods 63 drive the multiple first support members 65 to move inward at the same time. During this process, the capacitor aluminum shell will fall into the receiving box 4 through the unloading opening 67 due to the unstable center of gravity. After all the capacitor aluminum shells have fallen into the receiving box 4, the second hydraulic cylinder 61 controls the first support member 65 to return to its original position. The unloading unit 6 can control multiple capacitor aluminum shells to perform unloading operations at the same time, which greatly shortens the unloading time, improves the flanging efficiency, and also reduces the labor intensity of the operator.

[0025] It should be noted that: 1. The structure of the first support member 65 is the same as that of the second support member 66. The first support member 65 includes an arc-shaped plate that fits the outer wall of the capacitor aluminum shell and a support plate that supports the bottom of the capacitor aluminum shell, and the arc-shaped plate is arranged at the upper end of the support plate; 2. The first hydraulic cylinder 2 and the second hydraulic cylinder 61 are electrically connected to a controller provided on the machine 1; 3. The inner cavity of the material receiving box 4 is provided with an elastic buffer pad, which can buffer the collision between the capacitor aluminum shell and the material receiving box, prevent the capacitor aluminum shell from being deformed due to collision, and has a good protective effect on the capacitor aluminum shell.

[0026] As a preferred implementation in this embodiment, Figure 1 As shown, the bottom plate of the material receiving box 4 is inclined, and a discharge opening is provided on the material receiving box 4 at the lowest point close to the bottom plate.

[0027] A receiving bucket can be placed on the side where the discharge opening is set to receive the materials. The capacitor aluminum shell dropped into the receiving box 4 will move downward along the inclined surface of the inclined bottom plate and finally fall into the receiving bucket.

[0029] Since the machine 1 has a certain height, if the capacitor aluminum shell is allowed to automatically fall into the receiving bucket, it is easy to cause collision damage to the capacitor aluminum shell, so a U-shaped guide plate 5 and a rotation adjustment unit are provided. The elastic buffer pad can prevent the capacitor aluminum shell from rolling down, that is, reduce its descending speed. At the same time, the rotation adjustment unit can be used to adjust the inclination angle of the U-shaped guide plate 5 as needed, and the speed at which the capacitor aluminum shell finally leaves the U-shaped guide plate 5 can be changed by the inclination angle of the U-shaped guide plate 5. The rotation adjustment unit can be used to adjust and make the discharge end of the U-shaped guide plate 5 vertically downward. At this time, the U-shaped guide plate 5 is completely located directly below the machine 1, which can reduce the overall space occupied by the device.

[0030] As a preferred implementation in this embodiment, Figure 1 and Figure 4 As shown, the rotation adjustment unit includes a rotating shaft 7 rotatably arranged at the lower end of the material receiving box 4, and the U-shaped material guide plate 5 is rotatably connected to the material receiving box 4 through the rotating shaft 7. A worm gear 8 is fixedly sleeved on the rotating shaft 7, and the worm gear 8 is meshedly connected with a worm 9 rotatably arranged on the outer wall of the material receiving box 4, and a manual shaking plate 10 is installed on the outer end of the worm 9.

[0031] When in use, the U-shaped material guide plate 5 can be rotated by turning the manual shaking plate 10, and the transmission connection between the worm 9 and the worm wheel 8 has a locking effect, so that the U-shaped material guide plate 5 can be locked at any position.

[0032] As a preferred implementation in this embodiment, Figure 1 As shown, the lower end of the U-shaped material guide plate 5 is configured as a narrow opening.

[0033] The narrow opening at the lower end of the U-shaped material guide plate 5 can be provided with a material gathering function, so that the capacitor aluminum shells can be centrally arranged and placed in the material receiving bucket.

[0034] Finally, it should be noted that the above is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
