Technical Field

[0001] The utility model relates to the technical field of blanking in the production and processing of capacitors, in particular to a blanking device for the production and processing of aluminum electrolytic capacitors. Background Technique

[0002] The aluminum electrolytic capacitor has an aluminum cylinder as the negative electrode, which contains a liquid electrolyte inside, and a bent aluminum strip is inserted as the positive electrode. It also needs to be treated with a DC voltage to form an oxide film on the positive electrode plate as the dielectric. Its characteristics are large capacitance, but large leakage current, poor stability, and positive and negative polarities. It is suitable for power supply filtering or low-frequency circuits. When using it, do not connect the positive and negative poles reversely.

[0003] However, in the existing technology, most of the existing aluminum electrolytic capacitors are cylindrical. If the aluminum plate is directly blanked, it can only be blanked into a circular plate, and it is impossible to realize a die for blanking into a cylindrical shape. During the blanking process of the aluminum plate, the formed cylindrical die is likely to remain in the blanking knife. Therefore, it is necessary to realize that the die after blanking can be automatically separated conveniently, so as to carry out the blanking work again.

[0004] Therefore, we need a blanking device for the production and processing of aluminum electrolytic capacitors to solve the problems of the existing blanking of aluminum electrolytic capacitors in production and processing, and it can also realize the automatic demoulding of the blanked materials.

[0007] Preferably, the top surface of the lower pressure plate is fixedly connected to the bottom end of a cavity shell, the top inner surface of the cavity shell is fixedly connected to the top end of a first return spring, the bottom end of the first return spring abuts against the top surface of a push rod, and the surface of the push rod is movably connected inside the lower pressure plate and the disassembly knife cylinder.

[0008] Preferably, a pad mounting groove is formed on the top surface of the bottom plate. A die pad is inserted on the surface of the pad mounting groove. The inner parts of the bottom plate and the die pad are movably connected to the surface of a second limiting guide rod. The top surface of the second limiting guide rod is fixedly connected to the bottom surface of the lower die block. A second return spring is arranged on the surface of the second limiting guide rod.

[0009] Preferably, a powerful spring is sleeved on the outer surface of the first limiting guide rod.

[0010] Preferably, the inner top surface of the support frame of the blanking operation table is fixedly connected to the base of an electric telescopic pump. The end of the power output shaft of the electric telescopic pump abuts against the top surface of the cavity shell. A powerful spring is arranged on the top surface of the blanking operation table.
