Description
Technical field
The utility model belongs to grass trimmer parts technical field, more particularly, to a kind of high-strength ductile cast iron flange.
Background technique
In recent years, due to the improvement of people's living standards, the home environment of people is made to obtain bigger improvement, electric garden
The development of tool greatly reduces the labor intensity of the mankind, improves work efficiency.
Grass trimmer is also known as weeder, grass mower, lawn mower etc., it be it is a kind of for cutting the grass on a lawn, the electricity of vegetation etc.
Dynamic graden machine tool.Grass trimmer is easy to touch other higher sundries of the hardness such as stone during use, existing
The flange hardness that grass trimmer is used to connect blade is low, and impact resistance is poor, and the prominent power that is hampered is easy to the connecting key of blade, ring flange
Impact is brought, blade breakage or connecting key is caused to be broken.
Utility model content
In place of the purpose of this utility model is the deficiencies in the prior art to be solved, and provide that a kind of wearability is good, shock resistance
The strong high-strength ductile cast iron flange of ability.
The purpose of this utility model is solved through the following technical scheme:
A kind of high-strength ductile cast iron flange, including flange body, it is characterised in that: the flange body includes ring flange
Inner sleeve, ring flange housing and inner-outer sleeve connector；The material of the flange body is spheroidal graphite cast-iron；
The ring flange housing is annulus cylindricality, and ring flange inner sleeve is annulus cylindricality, ring flange housing central axis and method
Blue disk inner sleeve central axis coincides, and multiple inner-outer sleeve connectors are uniformly provided between ring flange housing and ring flange inner sleeve；It is interior
It is connect on the outside of housing connector with ring flange housing inner sidewall bottom, on the inside of inner-outer sleeve connector and in ring flange inner sleeve lateral wall
Portion's connection；The ring flange lining the outer surface of is provided in the axial direction with keyway, is equipped with rubber layer in keyway；The inner-outer sleeve connector
On offer mounting hole.
Preferably, inner-outer sleeve connector described in the utility model and ring flange housing junction are circular sliding slopes；In described
Housing connector and ring flange inner sleeve junction are circular sliding slopes.
Preferably, the number of inner-outer sleeve connector described in the utility model is 3 or more.
Preferably, flange body integrally casting shaping described in the utility model.
Compared to the prior art the utility model have the characteristics that and the utility model has the advantages that
1, flange body includes ring flange inner sleeve, ring flange housing and inner-outer sleeve connector, the number of inner-outer sleeve connector
It is 3 or more, structural stability is preferable, and material therefor is fewer than conventional flange disk material, it can effectively mitigate grass trimmer weight,
Reduce production cost.
2, by the structure optimization to flange body, material uses the disposable casting and forming of high-strength ductile cast iron, intensity
Height, performance is good, securely and reliably, not cracky fragmentation, it is subsequent using machining, guarantee its precision size peace weighing apparatus property and it is original
Flange compare, intensity improves 30%, is able to satisfy the use environment of some high loads, enhances reliability in use
And safety.
3, when grass trimmer is being easy to touch other higher sundries of the hardness such as stone using in the process, setting is in keyway
The resistance that interior rubber layer can slow down prominent chance brings impact to the connecting key of blade, ring flange, effectively avoids the breakage of blade
With the fracture of connecting key, safety and service life when grass trimmer uses are improved.
Detailed description of the invention
Fig. 1 is the utility model schematic diagram of main cross-sectional structure book.
Fig. 2 is the utility model present invention looks up structural representation.
Specific embodiment
The utility model is described in further details below in conjunction with attached drawing.
As shown in Figure 1 and Figure 2, a kind of high-strength ductile cast iron flange, including flange body, the flange body include method
Blue disk inner sleeve 1, ring flange housing 2 and inner-outer sleeve connector 3.The material of flange body is spheroidal graphite cast-iron, and flange body is integrally cast
Cause type.
Ring flange housing 2 is annulus cylindricality, and ring flange inner sleeve 1 is annulus cylindricality, 2 central axis of ring flange housing and flange
1 central axis of disk inner sleeve coincides, and multiple inner-outer sleeve connectors 3 are uniformly provided between ring flange housing 2 and ring flange inner sleeve 1.
3 outside of inner-outer sleeve connector is connect with 2 inner sidewall bottom of ring flange housing, outside 3 inside of inner-outer sleeve connector and ring flange inner sleeve 1
Connection in the middle part of side wall.
By the structure optimization to flange body, material uses the disposable casting and forming of high-strength ductile cast iron, and intensity is high,
Performance is good, securely and reliably, not cracky fragmentation.It is subsequent to use machining, guarantee its precision size peace weighing apparatus property and original method
Orchid is compared, and intensity improves 30%, is able to satisfy the use environment of some high loads, enhances reliability and peace in use
Quan Xing.
1 outer surface of ring flange inner sleeve is provided in the axial direction with keyway 4, is equipped with rubber layer 5 in keyway 4.On inner-outer sleeve connector 3
Offer mounting hole 6.When grass trimmer is being easy to touch other higher sundries of the hardness such as stone using in the process, setting exists
The resistance that rubber layer 5 in keyway 4 can slow down prominent chance brings impact to the connecting key of blade, ring flange, effectively avoids blade
Breakage and connecting key fracture, improve grass trimmer use when safety and service life.
Preferably, inner-outer sleeve connector 3 and 2 junction of ring flange housing are circular sliding slopes.Inner-outer sleeve connector 3 and flange
1 junction of disk inner sleeve is circular sliding slopes.Circular sliding slopes can effectively avoid junction stress from concentrating, and prevent from being broken.Inner-outer sleeve connection
The number of part 3 is 3 or more.
The specific embodiments described herein are merely examples of the spirit of the present invention.The utility model institute
Belonging to those skilled in the art can make various modifications or additions to the described embodiments or using similar
Mode substitute, but without departing from the spirit of the present application or beyond the scope of the appended claims.
