Description
Technical field
The utility model relates to alloy blade technical fields, more specifically to a kind of high welding quality strip cut paper
Blade.
Background technique
Paper cutting blade is paper cutter one of the ost important components, is used in automatic paper cutting machine, numerical control slitter, program-controlled cut paper
The dedicated paper cut paper cutting blade of all kinds of high-grade paper cutters such as machine, can be to offers high-precision paper such as press, packing businesses
It cuts, the sharpness and service life of paper cutting blade largely affect the working efficiency of paper cutter.Paper cutting blade is by closing
Golden blade and blade base high temperature welding-on form, and the combination of alloy blade and blade base determines the service life of blade, and
Paper cutting quality.
For strip paper cutting blade, be primarily present in production: alloy blade in the welding process, often occur rosin joint,
Solder skip, fracture；It in grinding process, often bursts, crack phenomenon, very big puzzlement and economic loss is caused to enterprise.
To find out its cause, the strip paper cutting blade processing technology of most original, is that alloy blade and blade base are welded as one using welding rod
Body can make cutter hub uneven heating even, often in the process welded since hand papercutter length is longer using the mode of welding rod
In, before welded place be just broken.Improvement technique starts to use adds one between blade base and alloy blade
The mode of layer silver soldering piece realizes connection, but is although made moderate progress using silver soldering piece, and it is even that there are still uneven heatings, and cutter hub is caused to be broken
The problem of, and the cutter hub processed can also find that there are many stomatas inside it through carrying out flaw detection, this can all seriously affect and cut
The yield rate and service life of paper blade.
Through retrieving, China Patent No. ZL201621191062.6, authorized announcement date is on September 12nd, 2017, innovation and creation
Title are as follows: a kind of reinforced welded shield alloy scraper cutter, this application include scraper body, knife beam, are located at scraper body
The carbide chip of end is equipped with metal mesh and silver-bearing copper weld tabs, is being brazed between the scraper body and carbide chip
It in the process, can be equal after melting silver-bearing copper weld tabs by increasing by one layer of metal mesh between alloy cutter hub and carbide chip
Even is distributed between alloy cutter hub and carbide chip, improves soldering strength, and weld seam has slag inclusion to split after avoiding soldering
Line.But what this application first related to is scraper cutter, and paper cutting blade can not be suitable for by improving it, secondly, this application
One layer of metal mesh and silver-bearing copper weld tabs are only set between scraper body and carbide chip, in alloy cutter hub and carbide cutter tool
Reliably there are hidden danger for welding aspect between piece.
