Description

Technical Field

[0001] The utility model relates to the field of capacitor aluminum shell bolt production, in particular to a capacitor aluminum shell bolt thread rolling machine. Background Art

[0002] Bolt capacitor is a capacitor whose structure consists of a metal bolt, two metal washers and a dielectric material. When the bolt and the washers are tightened, the dielectric material is squeezed between the two metal washers to form a capacitor structure.

[0003] When producing bolt capacitors, the bolts above them need to be processed. One bolt capacitor usually requires two bolts to assemble. In the prior art, ordinary thread rolling machines can only produce one bolt at a time, and the production efficiency is low, which is difficult to meet the production needs of bolt capacitors. If the production speed of bolts needs to be increased, two drive sources are usually required to drive two thread rolling machines at the same time. It is difficult to achieve a single drive source to simultaneously drive double thread rolling plates to thread the bolts.

[0004] In view of the above technical defects, a solution is now proposed. Utility Model Content
