Material shaft of coiling machine

Abstract

The invention discloses a material shaft of a coiling machine. The material shaft comprises a material shaft body. The material shaft is characterized in that a three-jaw expansion mechanism and a material shaft axial position adjusting mechanism are arranged on the material shaft body, wherein the material shaft is fixedly connected with a coiling machine tool through a rear base on the material shaft axial position adjusting mechanism. According to the material shaft in the structure, materials are fixed by adopting the three-jaw expansion mechanism, the materials of different widths are automatically centered, the coaxiality of the materials with the material shaft is greatly increased, and wrinkles of electric capacitor elements in the coiling process are effectively reduced; the mode of fixing the materials by the three-jaw expansion mechanism is applicable to the materials with various widths, the structure is reasonable and compact, the materials are conveniently disassembled and assembled, the working intensity of operators is reduced, the production efficiency is improved, and the materials are good in axial position adjustment stability, so that the material shaft is applicable to a conventional tension mechanism, can be still used for carrying out the adjustment on the axial position of the materials, and is good in axial position adjustment stability, and the adjustment operation mode of the tension and the axial positions of the materials are not changed.

Description

technical field [0001] The invention relates to a coiling machine, in particular to a material shaft of the coiling machine used in the element coiling process of the electric capacitor manufacturing process. Background technique [0002] The international power capacitor manufacturing industry regards component rolling as one of the key processes in the industry. Rolling machine is a kind of equipment used for rolling power capacitor components. It has an important impact on the quality of components in power capacitors. The quality of components directly affects the quality of power capacitors. One of the main causes of power capacitor damage is partial discharge. To solve the problem of partial discharge is to minimize the uneven distribution of the electric field. For the component rolling process, one way to reduce the uneven distribution of the electric field is to reduce wrinkles. Therefore, how to reduce the generation of wrinkles in the process of component rolling...

Problems solved by technology

[0003] The original material shaft of the rolling machine (the shaft that holds the material in the component rolling process of the power capacitor manufacturing process, also known as the "material shaft") uses a cone to center the material. The material shaft of this structure is aligned with the material. The adaptability of the width is small. When the width of the material is narrow, it is necessary to use an extension sleeve to fix the material, so that it is difficult to ensure the coaxiality of the material and the material axis, and the rolled components are prone to wrinkles, and for materials of different widths, matching Various specifications of extension sets, the material is inconvenient to disassemble
