Abstract

The invention discloses a capacitor aluminum cover plate material treatment method. The capacitor aluminum cover plate material treatment method comprises the following steps that firstly, in the extrusion direction, at the position away from an extrusion die outlet by 1-1.5 m, a 3 m quenching water tank is arranged, and cooling water is led in; secondly, a hot-extruded capacitor aluminum cover plate is conveyed into the quenching water tank to be cooled at the speed of 8-12 m / min, and the hot-extruded capacitor aluminum cover plate is cooled to 85-95 DEG C or below; thirdly, the cooled capacitor aluminum cover plate is clamped into a straightening device and is stretched; fourthly, the stretched capacitor aluminum cover plate edge is cut off, and the edge size is 2-4 cm; and fifthly, after aging treatment is finished, furnace opening is conducted, the capacitor aluminum cover plate is taken out, and natural cooling is conducted in air to the room temperature. The problems that in theprior art, certain damage can be caused to an extruder, and a capacitor aluminum shell can be low in hardness and poor in tenacity are solved.

Description

technical field [0001] The invention belongs to the improvement field of capacitor aluminum cover plates, in particular to a processing method for capacitor aluminum cover plate materials. Background technique [0002] A capacitor, usually referred to simply as its ability to hold charges as capacitance, is a device that holds charges. Capacitors are one of the electronic components widely used in electronic equipment. They are widely used in DC blocking, coupling, bypass, filtering, tuning loops, energy conversion, control, etc. in circuits. Any two capacitors that are insulated from each other and are very close A capacitor is formed between conductors (including wires). [0003] The existing capacitor aluminum cover material is sent out from the factory and will be directly processed and used in the capacitor. The bending of the material itself needs to be adjusted by the automatic extruder, which will undoubtedly cause certain damage to the extruder and will The proble...
