Title:
GRINDSTONE GUIDE, PRODUCTION LINE AND PRODUCTION METHOD PERTAINING TO RECHARGEABLE BATTERY CORE PRODUCTION
Document Type and Number:
WIPO Patent Application WO/2017/126139
Kind Code:
A1
Abstract:
The present invention limits the occurrence of burrs and scratches on the two ends of a pipe-type core for a rechargeable battery. This grindstone guide (20) is for guiding a cutting grindstone (10) for cutting pipes when manufacturing pipe-type cores for rechargeable batteries and is provided with: pipe bundle supports (22, 23, 24) for holding one or multiple pipe bundles, in which material pipes have been bundled, side by side; and guiding members (22, 23) for guiding the cutting grindstone (10). The guiding members (22, 23) have a pair of guiding surfaces (30) that contact the side surfaces of the cutting grindstone (10) and the guiding surfaces (30) are formed with sintered diamond or cemented carbide. The pipe bundle supports (22, 23, 24) have a holding frame (27) for juxtaposing the multiple pipe bundles in parallel therein and immobilizing same. The guiding surfaces (30) are preferably disposed in a U-shape so as to surround the holding frame (27) and opens towards the side opposite to the cutting grindstone (10).
