Abstract
The invention discloses a method for processing a rotary cultivator rotating knife, which comprises a rotary cultivator rotating knife which is processed, wherein the rotary cultivator rotating knife comprises a long knife body, the knife body is bent to be an arc shape toward the thickness direction, a cutting edge portion is arranged on a bent outer radian position of the knife body, the cutting edge angles are in 10 degrees-18 degrees, and pressing blades and mounting bolts are arranged. The method for processing the rotary cultivator rotating knife comprises the steps: 1 sintering: metal powder is uniformly spilled into a die of a blank which needs to be made and is struck off, and then the metal powder in the die is pressed to mold, and then is combined to sinter, thereby sintering the bent knife body, the cutting edge portion, the mounting bolts and the pressing blades; 2 grinding and repairing the cutting edge portion: a cutting edge of the cutting edge portion is ground and repaired by using grinding wheels; and 3 processing a safety bolt: the safety bolt is tapped. The method for processing the rotary cultivator rotating knife can solve the problem that existing rotary cultivator rotating knives are not reasonable in process method structure and not enough in plough depth.
Description
Technical field
The present invention relates to manufacture of agricultural machinery technical field, especially a kind ofly process the method that rotary shaft rotary cultivator revolves the processing method of cutter.
Background technology
What existing rotary shaft rotary cultivator revolves rotor revolves cutter, generally comprises microscler cutter hub, and cutter hub bends curved towards thickness direction, and the end revolving cutter is formed for dialling the pressure leaf portion pressing large grogs to curving.When the rotating shaft of revolving rotor rotates, revolve blade row to revolve cutter radial rolling, the soil in field is pushed aside by the pressure leaf portion of revolving cutter, is crushed by large grogs simultaneously, soil is ploughed ploughs carefully more broken, but because the structure revolving cutter makes to revolve cutter, to enter the degree of depth of soil limited, although be conducive to hack, the degree of depth of ploughing plough is inadequate, generally need to use the rotary cultivator of vertical shaft type to carry out ploughing plough, want to obtain comparatively ideal arable land situation, need to plough plough twice, extremely bother.Thus need to process a kind of can take into account broken thin degree and the degree of depth revolve cutter, to meet the demand in market.
Summary of the invention
Problem to be solved by this invention is to provide the processing method that a kind of rotary cultivator revolves cutter, to solve the processing method unreasonable structure that existing rotary cultivator revolves cutter, ploughs the problem that the degree of depth of plough is inadequate.
In order to solve the problem, technical scheme of the present invention is: the processing method that this rotary cultivator revolves cutter comprises a kind of rotary cultivator of processing and revolves cutter; Described rotary cultivator revolves cutter and comprises microscler cutter hub, described cutter hub bends curved towards thickness direction, the outer radian position that described cutter hub is bending has cutting edge portion, the blade angle in described cutter hub cutting edge portion is within the scope of 10 ° ~ 18 °, the end bilateral symmetry of described cutter hub is provided with the curved pressure leaf for dialling the large grogs of pressure of two bending tablets, described pressure leaf bends to the direction, cutting edge portion of described cutter hub, and described cutter hub root is provided with protruding installation bolt;
Its procedure of processing is as follows: A sinters: to be spilled into equably by metal dust in the die of the required blank made and to strike off, then by compressing for the metal dust in die, then carrying out combined sintering, sintering out bending cutter hub, cutting edge portion, install bolt and pressure leaf; Cutting edge portion repaiied by B mill: use grinding-wheel grinder to repair the cutting edge in cutting edge portion; C process safety bolt: be safety cock tapping.
Owing to have employed technique scheme, the present invention compared with prior art has following beneficial effect:
A kind of rotary cultivator can taking into account broken thin degree and the degree of depth of processing method processing that this rotary cultivator revolves cutter revolves cutter, to meet the needs in market.The cutting edge that this rotary cultivator revolves cutter is opened and is being revolved the bending outer radian position of cutter, the cutting of cutter along the radial direction of rotating shaft is revolved to increase, the i.e. cutting in vertical direction depth of soil direction, the end bilateral symmetry of cutter hub is provided with the curved pressure leaf for dialling the large grogs of pressure of two bending tablets, both the large grain grogs stirring and provoke pressure group and dig can have been played when cutter hub vertical direction is cut, the holding power of vertical direction can be increased again, impose the intensity of vertical direction cutting.The processing method that this rotary cultivator revolves cutter uses Hardmetal materials, adopt the mode of combined sintering, disposable sinters out whole shapes that whole rotary cultivator revolves cutter, not high owing to revolving the required precision of the cutter edge of a knife, thus adopt the mode of grinding to grind and repair cutting edge portion, make the whole cutter that revolves have enough intensity, this method is simply efficient.
Accompanying drawing explanation
Fig. 1 is the front view that embodiment of the present invention rotary cultivator revolves cutter;
Fig. 2 is the left view that embodiment of the present invention rotary cultivator revolves cutter.
Detailed description of the invention
Below in conjunction with accompanying drawing, the embodiment of the present invention is described in further detail:
This rotary cultivator revolves the processing method of cutter, comprises a kind of rotary cultivator of processing and revolves cutter.Rotary cultivator as shown in Figure 1 and Figure 2 revolves cutter, comprise microscler cutter hub 1, cutter hub 1 bends curved towards thickness direction, the outer radian position that cutter hub 1 is bending has cutting edge portion 1-1, the blade angle A=10 ° in the cutting edge portion of cutter hub 2, revolves the cutting of cutter along the radial direction of rotating shaft to increase, the i.e. cutting in vertical direction depth of soil direction, the scope that angle is 10 ° to 18 °, namely ensure that the sharpness of cutting, in turn ensure that the intensity of cutting.The end bilateral symmetry of cutter hub 1 is provided with the curved pressure leaf 2 for dialling the large grogs of pressure of two bending tablets, pressure leaf 2 bends to the 1-1 direction, cutting edge portion of cutter hub 1, both the large grain grogs stirring and provoke pressure group and dig can have been played when revolving the cutting of cutter 2 vertical direction, the holding power of vertical direction can be increased again, impose the intensity of vertical direction cutting.Cutter hub 1 root is provided with protruding installation bolt 1-2.The processing method that this rotary cultivator revolves cutter has taken into account broken thin two functions larger with ploughing the plough degree of depth of cultivated plough soil simultaneously, easy to use, is suitable for the cultivated plough in various soil field.
Its procedure of processing is as follows: A sinters: to be spilled into equably by metal dust in the die of the required blank made and to strike off, again by compressing for the metal dust in die, then carry out combined sintering, sinter out bending cutter hub 1, cutting edge portion 1-1, bolt 1-2 and pressure leaf 2 are installed; Cutting edge portion 1-1 repaiied by B mill; C process safety bolt 1-2: for safety cock attacks 1-2 screw thread.Use grinding-wheel grinder to repair the cutting edge in cutting edge portion, meet angle requirement.Use Hardmetal materials, adopt the mode of combined sintering, disposable the sinters out whole shapes that whole rotary cultivator revolves cutter, not high owing to revolving the required precision of the cutter edge of a knife, thus adopts the mode of grinding to grind and repaiies cutting edge portion, make the whole cutter that revolves have enough intensity.
In other embodiments, the angle A of revolving the cutting edge of cutter 2 can select any one numerical value between 10 ° to 18 °.
