Abstract
The invention discloses a processing method of a steel planing hoe, belonging to the technical field of agricultural machinery.A production process of the steel planing hoe comprises the steps of mechanically rolling a square steel into a flat steel by using a No. 45 medium carbon steel blank, and then blanking the flat steel into a blank; heating the blank to 1200 ℃, and mechanically rolling and rolling the blank into a convex blank hoe plate; stamping the convex blank hoe plate into a hoe plate in the shape of a steel plane hoe by using a stamping die, and pressing a mark; then pressing the hoe plate into an arc shape by using a friction press machine, and pressing a triangular reinforcing rib on the hoe plate; rolling the hoe cage by a press machine, and bending the hoe cage to form a steel plane hoe; quenching with chemical solution until the hardness reaches 45-50 HRC; polishing the steel-planing hoe, painting, drying and packaging to obtain a finished steel-planing hoe product; the invention has the advantages of few process procedures, high production automation degree, durability, good appearance degree, fuel source saving, little smoke dust waste and noise pollution, and is particularly suitable for industrial production.
Description
Technical field
The present invention relates to the agricultural machinery processing technique field, be specifically related to a kind of processing method of adjustable pocket bench plane hoe
Background technology
The process technology of domestic existing plane hoe all is to be raw material with the wastes of iron and steel, and its production technology is: the wastes of iron and steel fracture is processed into blank, is heated to 1200 ℃, forge for tens times with the pneumatic hammer warp and form; Product through this technology and manufacture of materials are come out digs hoe mouthful easy breach during use, be not durable, and it is asymmetric to dig hoe cage and plate face; And operation is many, yields poorly, and required time is long; The process relative complex, labor strength is big, and production cost is high; Moreover be exactly to waste raw material, waste energy, produce the flue dust discarded object and pollute noise serious.
In order to simplify said process, reduce cost, reduce equipment investment; State invention patent announcement CH101484265 discloses a kind of processing technology of new steel plate hoe in 25 days November in 2009, and it is to pick through steel plate being cut out the hoe that welding hoe cage processes, and has simplified the operation that forges that original steel picks; Shortened the time; Alleviated labor strength, but the adjustable pocket bench plane that is welded hoe mechanical strength is seriously not enough, is easy to rupture from the welding position.
So far, domestic all to produce adjustable pocket bench planes hoe all be to add two forger with little red stove to forge through tens times with pneumatic hammer and form still useless at present mechanization production, the production technology of global formation.
Summary of the invention
The present invention has overcome the deficiency of prior art, a kind of mechanization production is provided, does not need to weld, the processing method of global formation adjustable pocket bench plane hoe.
For solving above-mentioned technical problem, the present invention adopts following technical scheme:
A kind of processing method of adjustable pocket bench plane hoe, specifically procedure of processing is,
Earlier square steel is become band steel through mechanically rolling, become needed blank down;
With above-mentioned blank heating to 1200-1300 ℃, through mechanically rolling or be rolled into convex blank hoe sheet material;
2. with diel said convex blank hoe plate stamping is become to have the hoe plate profile of adjustable pocket bench plane hoe shape again;
3. with friction press above-mentioned hoe plate is pressed into arc then, extrudes the triangle reinforcement again;
4. with forcing press volume hoe cage, after bending hoe cage again, form the adjustable pocket bench plane hoe;
Quench with chemical solution, product hardness reaches 45-50HRC;
Adjustable pocket bench plane hoe sanding and polishing after just quenching, japanning are handled, dry, are packed, and process adjustable pocket bench plane hoe finished product.
In order to realize the present invention better, further technical scheme is:
As preferably: described square steel is the 45# steel.
As preferably: described chemical solution is sodium nitrate solution or sodium nitrite solution.
Compared with prior art, the invention has the beneficial effects as follows:
The present invention has changed the production technology of traditional adjustable pocket bench plane hoe, and existing without cut, stock utilization is high; The per pass molding procedure all has mould control, the simple easy operating of technology, simultaneously; Automaticity significantly improves; Labor strength greatly reduces, and can realize that industrialization produces in enormous quantities continuously, has improved production efficiency greatly.
The adjustable pocket bench plane hoe hoe that processes through this processing method is mouthful sharp, because the hoe cage is and the one-shot forming of hoe plate, has overcome former welding method and has been prone to from the shortcoming of weld fracture.Cost is low, and is durable in use, more energy-conservation more than 90% than traditional processing technology, reduces the pollution to environment, meets the industrial policy of country.
In sum, operation of the present invention is few, does not need welding, and the automated production degree is high, and durable, the outward appearance degree is good, the fuel savings source, and flue dust discarded object and noise pollution are few, are particularly suitable for suitability for industrialized production.
Description of drawings
Fig. 1 is a process chart of the present invention.
Wherein, the pairing name of each schematic flow sheet is called in the accompanying drawing:
The 1-square steel, the cross-sectional schematic in 1 '-square steel cross section, 2-band steel, 2 '-band steel cross-sectional schematic; The 3-blank, 3 '-blank cross-sectional schematic, 4-convex blank hoe sheet material; 4 '-convex blank hoe plate cross-sectional schematic, the hoe plate after the 5-punching press, the hoe plate cross-sectional schematic after 5 '-punching press; The triangle reinforcement that the 6-friction press extrudes, the triangle reinforcement cross-sectional schematic that 6 '-friction press extrudes, the hoe plate behind the 7-volume hoe cage; Hoe plate cross-sectional schematic behind 7 '-volume hoe cage forms the adjustable pocket bench plane hoe behind the 8-bending hoe cage, forms adjustable pocket bench plane hoe cross-sectional schematic behind 8 '-bending hoe cage.
The specific embodiment
Below in conjunction with Figure of description the present invention is done to specify further, but embodiment of the present invention is not limited thereto.
