专利说明:

A manufacturing method of rotarya edge of a sword for a farm implement}
[12] The present invention relates to a method for manufacturing a rotary blade for agricultural machinery, and more particularly, to reduce the material and at the same time shorten the manufacturing process.
[13] In general, the upper end of the rotary blade has an inclined cross section, the lower end has a right angled cross section, and one side of the rotary tape is formed in the overall L-shape.
[14] In the conventional method of manufacturing a rotary blade as described above, when assuming that the rotary blade 60 having a size of 50 centimeters is formed as shown in FIG. 1, the material 20 of 6 meters is cut at right angles by a length of 50 centimeters using a cutter. 12 pieces of blade material 30 for 50 centimeters are prepared.
[15] Twelve 50 centimeters of the blade material 30 prepared in the above cutting process is cut inclined so that an inclined cross section is formed on one side separately, and the cut pieces 40 are discarded.
[16] Then, by supplying 50 centimeters of the blade material 30 one by one to form a tapered blade 31 by hot rolling, and to partially cut and band unnecessary parts by hot piercing to make a rotary blade.
[17] When the rotary blade is made in the same process as described above, the cut pieces 40 are cut out from the 50-cm blade material 30, and thus, about 50 centimeters of the blade material 30 are lost.
[18] In addition, the cutting process is also doubled because the cutting material is to be inclined and cut at right angles.
[19] Therefore, there is a problem that not only the cost of the material loss and the cutting process rises but also the production efficiency decreases.
[20] The present invention is to prepare the material to the length of the two rotary blades in order to solve the above-mentioned problems, but prepared by summing the length of the cutting pieces in the length of the inclined cross-section abutting each other and at the same time to roll the hole and taper blade In view of this, the purpose is to cut the material and shorten the manufacturing process by cutting.
[1] 1 is a process diagram showing a conventional manufacturing method
[2] 2 is a process of processing the material by the manufacturing method of the present invention

[10] 6: tapered blade
[11] 7: slope section
[21] Hereinafter, a method for manufacturing a rotary blade for agricultural machinery of the present invention will be described in detail with reference to the accompanying drawings.
[22] Rotary blade (1) Prepare the material (2) with two lengths, but be sure to add the length of the inclined cross-section (7) to each other and the length of the cutting piece (3) necessary for cutting.
[23] Prepare the raw material (2) above and inclined at the intermediate point in the hot state ( The two cutting edges (1 ') (1 ″) are obtained by cutting into a square shape to remove the cutting piece (3), the hole (5) and the blade forming portion (4) (4').
[24] Then, by supplying the rotary blade material (1 ') (1 ") one by one to form a tapered blade (6) by a hot rolling process, and finally the banding process to make a rotary blade (1).
[25] Example 1
[26] When the long side (A) of the rotary blade is 50 centimeters and the short side (B) makes the 40 centimeters of the rotary blade (1), the inclined cross section (7) is brought into contact with the two rotary blade materials (1 ') (1 ″). 91.5 centimeters of material, which is 90 centimeters of treated and 1.5 centimeters of cut pieces (3), are prepared to obtain 1.5 centimeters of cut pieces (3) and 50 centimeters of rotary blade material (1 ') (1 ″). have.
[27] This is because 10 centimeters of the portions constituting the inclined cross section 7 are to be inclined to each other.
[28] This will give you 6 pieces of 91.5 centimeters of material using 6 meters of material, leaving 51 centimeters of material.
[29] As above, two rotary blades (1) can be made from 91.5 centimeters of material. Consequently, twelve 50 centimeters of rotary blades (1) are made from 5 centimeters and 49 centimeters of 6-meter material, and the remaining accumulated 51 centimeters can make one more rotary blade.
[30] In the cutting process, the 6-meter material is cut at 91.5 centimeters six times and By removing the hole 5 and the blade forming portion 4 and 4 'at the same time as the cutting piece 3, twelve rotary blade materials can be obtained. Rotary blade material can be obtained, eventually resulting in thirteen rotary blade materials in 6-meter lengths, reducing the cutting process.
[31] Rotary blade material (1 ') (1 ″) obtained by the above process is supplied one by one to form a tapered blade (6) by a hot rolling process, and finally the banding process to make a rotary blade (1).
[32] The present invention as described above can reduce the material by providing the material by summing the length of the two pieces of material of the rotary blade with the inclined cross-section but the length of the cutting piece, and remove the cutting piece and the hole and the blade forming portion of the middle portion at the same time As a result, the production process can be shortened, so in conclusion, more rotary blades can be produced from the same length of material, and the production process can be shortened to reduce the production cost.
