Method for processing steel plane hoe

Abstract

The invention discloses a method for processing a steel plane hoe, which belongs to the technical field of agricultural machinery. The production technology of the steel plane hoe comprises the following steps of: using a 45# medium carbon steel billet, mechanically rolling a square steel into a flat steel, and adding a blank forming material; heating the blank forming material to 1200 degrees centigrade, mechanically rolling into a convex blank hoe plate material; using a punch die to punch the convex blank hoe plate material into a hoe plate with a steel plane hoe shape, and marking; using a friction pressure machine to press the hoe plate into an arc shape and to press out a triangular reinforced rib on the hoe plate; using the pressure machine to roll up a hoe cage, and bending the hoe cage to form the steel plane hoe; quenching by a chemical solution until the hardness reaches 45-50HRC; and polishing, painting, drying and packaging the steel plane hoe to obtain the steel plane hoe as a finished product. The method provided by the invention has the advantages of few working procedures, high automation level of production, durability, fuel source economy, beautiful appearance, few smoke wastes and less noise pollution, and is particularly suitable for industrial production.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery processing, in particular to a processing method for a steel planer hoe Background technique [0002] The processing technology of the existing planer hoes in China is all using scrap iron and steel as raw materials. The products produced by the planer hoe are easy to be chipped when used, and are not durable. The planer hoe cage is asymmetrical to the board surface, and there are many processes, low output, long time required, relatively complicated process, high labor intensity for workers, and high production costs. In addition, raw materials are wasted, energy is wasted, smoke and dust are generated, and pollution and noise are serious. [0003] In order to simplify the above process, reduce costs, and reduce equipment investment, China Invention Patent Announcement No. CH101484265 on November 25, 2009 disclosed a new type of steel plate hoe processing technology, which is proc...

[0002] The processing technology of the existing planer hoes in China is all using scrap iron and steel as raw materials. The products produced by the planer hoe are easy to be chipped when used, and are not durable. The planer hoe cage is asymmetrical to the board surface, and there are many processes, low output, long time required, relatively complicated process, high labor intensity for workers, and high production costs. Moreover, it is a waste of raw materials, waste of energy, generation of smoke and dust waste and serious pollution and noise

[0003] In order to simplify the above process, reduce costs, and reduce equipment investment, China Invention Patent Announcement No. CH101484265 on November 25, 2009 disclosed a new type of steel plate hoe processing technology, which is processed by cutting and welding steel plate hoes. , simplifies the forging process of the original steel hoe, shortens the time, and reduces the labor intensity of the workers, but the mechanical strength of the welded steel planer is seriously insufficient, and it is easy to break from the welded part

[0004] So far, all steel planing hoes produced in China are made by forging dozens of times with a small red furnace and two forging air hammers. At present, there is no mechanized production and integral molding production technology.
