Problems solved by technology

[0002] The cheap sickles on the market are all made of pure steel plates, which have the following problems: 1. Because the steel plates are deformed after quenching, the general manufacturers use narrow-range quenching, so that the width of the cutting edge is only about 10mm, and the service life is not long; 2. It is made of thin steel plate, the strength is not high, and it is easy to deform, while the thick steel plate is pressed, it is difficult to grind after blunt; 3, easy to chip

Embodiment Construction

[0013] The following steps of the present invention are as follows: the metal sheet is blanked into the shape of a knife plate, the back of the knife plate is folded, the folded joint is welded, one side of the knife plate is coated with an anti-carburizing paint, and then chemically treated, the knife plate and the trousers are welded together, The trousers are stamped and formed, ground, quenched, tempered, straightened, coarsely ground, and finely ground into products.

[0014] With reference to the accompanying drawings, the present invention first blanks the metal sheet into a knife plate shape, folds a small part of the back of the knife plate, and then welds the folded joints, and the knife plate 2, the folding head 3 and the knife trousers 1 are welded together. Because a small part of the back of the knife board is folded, the folded seam gradually becomes thinner from the root to the head, which increases the overall strength of the knife board, especially the root, a...

Abstract

The invention relates to a method for preparation of sickle. It contains the following steps: cutting the metallic sheet, folding the back, welding the seam, coating one face of the knife plate with a masking paste and then with chemical treatment, welding the trouser- part material with the knife plate, punching the trouser-part material to mould, whole grinding, quenching, tempering, aligning, coarse grinding, and correct grinding to prepare the product. The sickle is intense and not easy to be out of shape or to break; and the sickle can be produced by industrialization.

Description

technical field [0001] The invention relates to a method for processing sickles. Background technique [0002] The cheap sickles on the market are all made of pure steel plates, which have the following problems: 1. Because the steel plates are deformed after quenching, the general manufacturers use narrow-range quenching, so that the width of the cutting edge is only about 10mm, and the service life is not long; 2. It is made of thin steel plate, the strength is not high, and it is easy to deform, while the thick steel plate is pressed, it is difficult to grind after blunt; 3, easy to chip. In order to solve the problem of easy deformation of the sickle, "A Production and Processing Method of Sickle" (patent application No. 00112493) was specially designed, which included the following steps. First, the thin metal material was blanked and processed into a blade shape, and then the wide mouth of the blade was machine-ground, and then Press the back with a punching machine, ...
