Abstract
The present invention discloses a sickle production and processing method, which relates to a method for producing and processing sickles. The present invention comprises the following steps that the blanking of sheet metal is carried out; the back of the sheet metal is folded; the folding joint positions are welded; one side of a sickle plate is coated by masking paste; then, the chemical treatment is carried out; the trouser part material is together welded with the sickle plate; after the trouser part is stamped and formed, products are obtained by whole grinding, quenching, tempering, straightening, coarse grinding and fine grinding. Because the back is folded by the present invention, the joint positions are welded, the integral strength of the sickle plate is increased, and the sickle plate can not deform easily. The sickle plate is carried out with chemical treatment, and the treatment comprises carburization and carbonitriding treatment. A super thin hardened layer is formed on the surface of a sickle plate; because the hardened layer is thin, the cutting resistance performance is good, the sickle can not be notched easily and is easy to grind and back cut, and is welcomed by users. The sickle can realize industrialized production, and has the advantages of low price, stable and reliable quality and long service life.
Description
Technical field
The present invention relates to a kind of method of processing reaping hook.
Background technology
Now cheap reaping hook on the market all is that the clean steel plate is pressed into, and there is following problem in it: 1, owing to be out of shape behind the steel plate quenching, so general producer adopts the close limit quenching, only about 10mm, service life is not long for the width that makes cutting edge; 2, be pressed into sheet metal, intensity is not high, yielding, and the steel plate compacting, with grinding difficult in blunt back; 3, easy breach.For solving the yielding problem of reaping hook, ad hoc having counted " a kind of sickle production and processing method " (number of patent application 00112493), may further comprise the steps, at first metal foil section bar blanking is processed into blade type, machine sharpening sheet is wide mouthful again, and utilize punch press to press the back of the body, then be successively: quenching, tempering, wide mouthful of cutter blade, manual mill osculum, polishing and cleaning.
Summary of the invention
The objective of the invention is at above-mentioned present situation, aim to provide a kind of reaping hook not yielding, be difficult for breach, long service life, production cost is low, efficient is high, steady quality, can realize the sickle manufacturing method of suitability for industrialized production.
The implementation of the object of the invention is that a kind of sickle production and processing method may further comprise the steps:
1) the sheet metal blanking becomes knife plate shape,
2) the knife plate back is folding, the welding of folding cross-stitch place,
3) the knife plate one side applies with masking paste, then carries out chemical treatment,
4) knife plate and trousers portion cloth are welded together,
5) trousers portion drawing,
6) whole mill, quenching, tempering, alignment, roughly grind, be finish-ground to product.
The present invention is because of folding with the knife plate back, and will fold the welding of cross-stitch place, increased the whole body intensity of knife plate, not yielding; Reaping hook is put into the carburizer carburizing, and the one side that does not apply masking paste is carried out chemical treatment, forms hardened layer as thin as a wafer, and anti-cutting property is good, be difficult for breach, and the blunt back of edge of a knife easy grinding is suitable for reading, very popular with users; This reaping hook energy suitability for industrialized production, price is low, steady quality is reliable, long service life.
Description of drawings
Accompanying drawing is the reaping hook of producing with the inventive method
The specific embodiment
Following steps of the present invention: the sheet metal blanking becomes knife plate shape, the knife plate back is folding, the welding of folding cross-stitch place, the knife plate one side applies with masking paste, then carry out chemical treatment, knife plate and trousers portion weld together, and the drawing of trousers portion is put in order mill, quenching, tempering, alignment, roughly ground, is finish-ground to product.
With reference to accompanying drawing, the present invention becomes knife plate shape with the sheet metal blanking earlier, and knife plate back sub-fraction is folding, then will fold the welding of cross-stitch place, and knife plate 2 welds together with cutter trousers portion 1 with folding 3.Because of knife plate back sub-fraction folding, folding cross-stitch place attenuation gradually from the root to the head, increased knife plate integral body, particularly root intensity, make reaping hook not yielding.The knife plate one side applies with masking paste, then carries out chemical treatment, and chemical treatment comprises carburizing, carbo-nitriding processing.When carrying out Carburization Treatment, reaping hook was put into the carburizer carburizing 40 ± 5 minutes, the surface that does not apply the one side of masking paste forms hardened layer as thin as a wafer, and anti-cutting property is good, be difficult for breach, and the blunt back of edge of a knife easy grinding is suitable for reading, very popular with users.
Claims (3)
1. sickle production and processing method is characterized in that may further comprise the steps:
1) the sheet metal blanking becomes knife plate shape,
2) the knife plate back is folding, the welding of folding cross-stitch place,
3) the knife plate one side applies with masking paste, then carries out chemical treatment,
4) knife plate and trousers portion cloth are welded together,
5) trousers portion drawing,
6) whole mill, quenching, tempering, alignment, roughly grind, be finish-ground to product,
Chemical treatment is that carburizing or carbonitriding is handled.
2. a kind of sickle production and processing method according to claim 1 is characterized in that folding cross-stitch place attenuation gradually from the root to the head.
