Abstract
The utility model discloses a base cutter with an embedded alloy cutter head, belonging to the technical field of mechanical machining cutters. The base cutter comprises a blade body, wherein the blade body comprises a mounting part and a cutting part; the mounting part is a bar-shaped cutter body; a row of mounting holes are formed in the mounting part; the mounting holes are circular truncated cone-shaped; one side of the cutting part far away from the mounting part is arc-shaped; and a cutter edge is further embedded at the top end of the cutting part. Due to adoption of the base cutter, the service life of the blade is effectively prolonged, and the cutter is prevented from being replaced frequently, so that the effects that the production cost is lowered and the working effect is improved are achieved, and moreover the blade is solidly mounted, is unlikely to drop off, and has the advantages that the structure is simple, the operation is convenient and the manufacturing is easy to carry out.
Description
Technical field
The utility model belongs to the machining tool technical field, specifically, relates to a kind of bed plate of inlaying alloy cutter head.
Background technology
Bed plate is being played the part of important role daily in cutting grass work.The sharpness of bed plate, attitude setting, bed plate angle all affect cuts grass product matter and cuts careless effect.The design of bed plate must meet two conditions, should have enough materials (thickness) to disperse to cut the heat that careless operation produces, and guarantees again to leave space below bed plate, in order to avoid bed plate is dawdled on lawn.
When cutting-height is higher, when the blade of grass of pruning place is more sparse, owing to not having enough blades of grass to carry out Cooling and Lubricator, the temperature at bed plate blade place can be higher.If now use thinner bed plate, because its material is not enough to rapid heat dispersing, and make the bed plate expanded by heating, cause bed plate accelerated wear test.Therefore, when cutting-height is higher, should select thicker bed plate.
When cutting-height is low, if use thicker bed plate, can cause the lawn of dawdling, bed plate bottom, not only cause the wearing and tearing on lawn, and the landform risen and fallen can hold up the hobboing cutter group, make cutting-height inconsistent, what the fluctuation shape occurs badly cuts careless outward appearance.In the time of serious, bed plate is upwards held up, thereby directly contacts and destroy the hobboing cutter blade with hobboing cutter.
Even but select right bed plate, bed plate in use also can rust, and the grit existed in lawn, rubble etc. all can be accelerated the wearing and tearing of blade, so just often need more allowing blade replacement, thereby increase cost, reduce production efficiency.
China Patent No.: 200920180839.2, open day: 2010-10-13, disclose a kind of name and be called the patent document for the bed plate of quintuplet lawnmower, this utility model discloses the bed plate for quintuplet lawnmower, include the cutter hub of bar shaped, be provided with row's installing hole on described cutter hub, the bottom edge of described cutter hub is provided with transverse blade.This utility model is simple in structure, with the bed plate in quintuplet lawnmower, is used in conjunction with, effective to the pruning of golf upper track grass.But this utility model blade cutting edge directly contacts with lawn, can accelerate the wearing and tearing of blade, and the service life of blade is low, often need more allowing blade replacement, can increase cost, reduce operating efficiency.
Summary of the invention
The problem that 1, will solve
Easy to wear for existing bed plate blade, often need more allowing blade replacement, can increase cost, reduce the problem of operating efficiency, the utility model provides a kind of bed plate of inlaying alloy cutter head, and this bed plate adopts the wolfram steel blade, there is the advantages such as high abrasion, high rigidity, often do not need more allowing blade replacement, reduce costs, increase work efficiency.
2, technical scheme
For addressing the above problem, the utility model adopts following technical scheme.
A kind of bed plate of inlaying alloy cutter head, comprise blade body, and described blade body comprises installation position and cutting position; Described installation position is the bar shaped cutter hub; Described installation position is provided with row's installing hole; Described installing hole be shaped as truncated cone-shaped; Described cutting position is arc away from a side of installation position; The top at described cutting position also is inlaid with blade.
Preferably, the material of described blade is carbide alloy.
Preferred, the material of described blade is wolfram steel, and described blade body material is the 45# steel.
Preferably, adopt the brazing welding between described cutting position and blade.
Preferably, the radius of the arc at described cutting position is 20-35cm.
More preferably, the radius of the arc at described cutting position is 28cm.
Preferably, the thickness of described blade is 1mm.
The utility model adopts at the cutting position of the cutter hub front end of 45# steel making welding wolfram steel cutter head, has strengthened hardness and the cutting power of cutter head, has increased the service life of cutter, does not often need more allowing blade replacement, thereby reduces production costs, and improves service efficiency.
3, beneficial effect
Than prior art, the beneficial effects of the utility model are:
(1) the utility model blade body comprises installation position and cutting position, and the cutting position studs with the blade that material is wolfram steel; And adopt the brazing welding between cutting position and blade, because wolfram steel has the characteristics of high rigidity, high abrasion, so adopt the wolfram steel blade can effectively improve blade service life, avoid often changing cutter, thereby reach, reduce production costs, the effect of increasing work efficiency;
(2) cutter hub that blade body of the present utility model is bar shaped, be provided with row's installing hole on cutter hub, installing hole be shaped as truncated cone-shaped, can make blade install more fastening, difficult drop-off;
(3) arc radius at cutting of the present utility model position is 20-35cm, can be pruned the blade of grass of differing heights;
(4) the utility model simple in structure, easy to operate, be easy to manufacture.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is left view of the present utility model.
The number in the figure explanation:
1, blade body; 2, blade; 3, installing hole; 11, cutting position; 12 installation positions.
Embodiment
For further understanding content of the present utility model, below in conjunction with Figure of description and specific embodiment, the utility model is described in detail.
Embodiment 1
