Abstract
The invention relates to the technical field of cutter manufacture, in particular to a manufacture method of a scraper special for obtaining corn stalk skins. According to the technical field, the method includes adopting a steel plate with the length of 10cm, width of 6cm and thickness of 3mm, digging a semi-circle with the radius of 2.5cm in the midpoint of the long edge of the steel plate, adopting an arc with the length of 6mm in the middle of the semi arc, expanding the radius of the arcs of two ends till reaching 2.8cm, grinding the middle convex arc into a blade, and blunting the other edges and angles of the steel plate finally. Since the blade of the scraper is an arc with length of 6mm, the widths of the scraped corn stalk skins are 6mm regularly, the operating efficiency is improved, and the dried skins meet the requirements.
Description
Technical field
The present invention relates to cutter manufacture technology field, particularly relate to a kind of facture obtaining maize stalk skin suede Special scraper knife.
Background technology
With universal cutter scraping maize stalk skin suede, because the edge of a knife is straight mouth, so the contact of the edge of a knife and maize stalk is point cantact, therefore, be wire with the skin suede that this straight mouth cutter scrapes, this not only makes the efficiency of rossing suede low, the more important thing is wire skin suede show as after drying soft excessively and elasticity is not enough.
Summary of the invention
The object of this invention is to provide a kind of facture obtaining maize stalk skin suede Special scraper knife, improve rossing efficiency and improve skin down quality simultaneously.
The object of the present invention is achieved like this: the steel plate getting a block length 10cm, wide 6cm, thick 3mm, the semicircle of a radius 2.5cm is cut out in the midpoint on long limit, the side of steel plate, the arc of one section of arc length 6mm is got at the middle part of semi-circular arc, the radius file of the circular arc line at this section of arc two ends is expanded to 2.8cm, again the camber line of middle part projection is worn into cutting edge, finally by other rib of steel plate and angle purifying.
Adopt such scheme can receive following remarkable result:
1., due to the camber line that scraper cutting edge is one section of arc length 6mm, so the 6mm of the width of the maize stalk skin suede scraped then for rule is wide at every turn, this had both improve operating efficiency, made again dried skin suede elasticity reach requirement.
2. not only technique is simple to press this programme making scraper, and uses very laborsaving.
Detailed description of the invention
Below in conjunction with embodiment, the invention will be further described.
Get the steel plate of a block length 10cm, wide 6cm, thick 3mm, the semicircle of a radius 2.5cm is cut out in the midpoint on long limit, the side of steel plate, the arc of one section of arc length 6mm is got at the middle part of semi-circular arc, the radius file of the circular arc line at this section of arc two ends is expanded to 2.8cm, again the camber line of middle part projection is worn into cutting edge, finally by other rib of steel plate and angle purifying.
Claims (1)
1. one kind obtains the facture of maize stalk skin suede Special scraper knife, it is characterized in that: the steel plate getting a block length 10cm, wide 6cm, thick 3mm, the semicircle of a radius 2.5cm is cut out in the midpoint on long limit, the side of steel plate, the arc of one section of arc length 6mm is got at the middle part of semi-circular arc, the radius file of the circular arc line at this section of arc two ends is expanded to 2.8cm, again the camber line of middle part projection is worn into cutting edge, finally by other rib of steel plate and angle purifying.
