A Continuous Stretch Forming Die for Capacitor Shell

Abstract

The invention relates to a continuous stretch forming die for capacitor shells, and relates to the technical field of capacitor shell production molds, including a lower die, an upper die arranged above the lower die, and an upper die arranged between the upper die and the lower die for A traction assembly that advances the automatic traction material belt; wherein, an auxiliary part is also provided between the upper mold and the lower mold, and the auxiliary part at least includes a pre-compression mechanism for pre-compressing the material belt on the upper surface of the lower mold and At least one ejecting mechanism for lifting the material belt upwards, the traction assembly includes a driven mechanism arranged on the lower mold for driving the material belt to move intermittently and arranged on the upper mold for driving the slave The driving mechanism moves the driving mechanism, wherein the traction assembly also includes a punching mechanism for punching out a punching hole on the material belt to cooperate with the driven mechanism. The invention has the effect of reducing the matching cost of the continuous mold.

Description

technical field [0001] The invention relates to the technical field of production molds for capacitor shells, in particular to a continuous stretching mold for capacitor shells. Background technique [0002] Capacitor (capacitor), as the name suggests, is a device that holds electric charge. Capacitors are one of the electronic components widely used in electronic equipment, and are widely used in DC blocking, coupling, bypass, filtering, tuning loops, energy conversion, control, etc. in circuits. There are many kinds of capacitors, such as aluminum electrolytic capacitors, tantalum electrolytic capacitors, ceramic capacitors, etc. The shells of metal capacitors are usually long and cylindrical. In production, the most basic method of capacitor housing is to use stretching. However, if the stretching is to be done in one step, the yield rate will decrease and the production cost will be indirectly increased. If the aspect ratio is relatively large, it will be technically di...

Problems solved by technology

[0008] The above-mentioned existing technical solutions have the following defects: when the material strip is processed by a continuous die, the material strip needs to be moved intermittently to realize the sequential conversion of the same part between the punches, and the movement of the material strip generally requires Relying on the winding device installed outside the continuous mold for traction, resulting in an increase in the matching cost of the continuous mold, so it needs to be improved
