A slidingrail is arranged on the base plate, and the first sliding plate and the second sliding plate are connected to the sliding rail. The pin forking mechanism is in a split type, and two parts of the pin forking mechanism are arranged on the first sliding plate and the second sliding plate respectively; the cutting mechanism and the shaping mechanism are also in a split type; in the machining direction, the pin forking mechanism, the pin arranging mechanism, the cutting mechanism, the shaping mechanism and the bending mechanism are sequentially arranged at equal intervals; the multifunctional forming device has the advantages that the pins are flat and uniform in length, twice bending is completed in one time, and the forming and bending efficiency is high.

Description

technical field [0001] The invention relates to the technical field of capacitor production, in particular to a multifunctional forming device for processing thin film capacitors. Background technique [0002] Film capacitors use metal foil as an electrode, and it is laminated with plastic films such as polyethylene, polypropylene, polystyrene or polycarbonate from both ends, and then wound into a cylindrical capacitor. According to the type of plastic film, it is called polyethylene capacitor (also called Mylar capacitor), polypropylene capacitor (also called PP capacitor), polystyrene capacitor (also called PS capacitor) and polycarbonate capacitor. Film capacitors are excellent capacitors due to their many excellent characteristics. Its main characteristics are as follows: non-polarity, high insulation resistance, excellent frequency characteristics (broad frequency response), and low dielectric loss. Based on the above advantages, film capacitors are widely used in ana...
