SCRAPER FOR WET SEALANT

Scraperwith two chamfers for collecting the sealant and preventing the surface from being dirtied.

Prior art

  Currently the faying surface sealant is applied in the drilling phase and left to cure. Afterwards, in the riveting process, the sealant scraping is carried out. The procedure to follow is:

1. Part of the interposition sealant is scraped, and then the capsulating and fillet sealantare applied.


2. While this task is carried out, the drilling process is continued.

  The problem is that drilling operations and sealant application overlap, and therefore the sealant is polluted with shavings. Furthermore, scraping the sealant once cured requires more labour than if done when fresh, which increases operation time.

Description of the invention

  The invention is made out of a scraperwith two chamfers for collecting the sealant and preventing the surface from being dirtied, as shown in the image.

  The novelty of this scraper is the chamfers, which allow the fresh sealant to be collected. If it is necessary to scrape cured sealant, the rear part of the scrapercan be used (2).

  The use of this new scraper requires operation procedure modification. The new procedure is as follows:

1. Apply faying surface sealant during the drilling phase.

2. In the riveting phase, remove all fresh sealant as the drilling operations are carried out.


3. Clean shavings produced during the drilling process.


4. Apply sealant.
