Description
Technical field
The utility model relates to a kind of carding element fields of textile machine, and in particular to a kind of resistance to compression and half wear-resisting arc
Type tooth top metallic card clothing.
Background technique
Carding element is the core equipment in spinning processing, and metallic card clothing is most important element on carding element again.With
Textile raw material, fabric property difference, especially all kinds of tencels, which are widely applied, proposes more the use of metallic card clothing
High requirement, the quality of metallic card clothing are mainly reflected on finish, sharpness, wear resistance, flatness and uniform quenching degree.So
And also there is some rib type teeth and major-minor toothing metal substantially based on pointed tooth type recently in the structure of metallic card clothing at present
Needle cloth, but the flute profile of existing metallic card clothing belongs to direct tooth type, and direct tooth type metallic card clothing has the following disadvantages: that 1, fiber stream is continuous
Pass through from needle friction between teeth so that tooth tip is gradually worn, the sharpness of needle tooth makes yarn quality degradation after failing, and leads
The service life of metallic card clothing is caused to greatly shorten；2, since the smaller i.e. anti-pressure ability of the forced area of metallic card clothing tooth tip is small and weak,
So that metallic card clothing work hour hands tooth is flexible under biggish external force, lodging；3, direct tooth type metallic card clothing is adding
Work manufacture i.e. when rushing tooth because on tooth punching machine device motor and the reasons such as the needle cloth speed of service be also easy to produce size tooth, and there is size tooth to deposit
Metallic card clothing be coated on roller that poor flatness i.e. feel is then presented is bad.
Utility model content
The purpose of this utility model is to overcome deficiency in the prior art, provide a kind of manufacture be easy, resistance to compression energy
Power is strong and resistance to compression with long service life and half wear-resisting camber tooth top metallic card clothing.
To achieve the above object, the utility model provides a kind of resistance to compression and half wear-resisting camber tooth top metallic card clothing includes base
Portion and the teeth portion on base portion, the teeth portion on base portion are spaced substantially equidistant several teeth, by concave surface arc between adjacent tooth
Connection, the tooth includes front flank, arc top surface, rear flank and the root portion connecting with base portion, and front flank is in rear flank
Linearly, front flank is connect with rear flank intersection by arc top surface, arc top surface it is arc-shaped and diagonally downward with the round and smooth company of rear flank
It connects；The rear flank of the tooth of front is connect with the front flank of subsequent tooth by concave surface arc rounding off between adjacent teeth；Arc-shaped
Crest top land radian is less than 90 °.
The front flank and base portion bottom surface are formed by angle α i.e. anterior angle, and angle α is 35 ° to 50 °, rear flank and base portion
Bottom surface is formed by angle γ i.e. relief angle, and angle γ is 30 ° to 45 °.
The height h of the tooth1For 2.00mm to 6.00mm, the wide w of the teeth portion of tooth1For 0.05mm to 1.00 mm, the arc top of tooth
Radius surface r1For 0.30mm to 0.80mm.The height h of base portion2For 1.20mm to 1.70mm, the width w of base portion2Extremely for 0.40mm
2.00mm；The radius r of the concave surface arc2For 0.25 mm to 0.40mm.
The utility model has the beneficial effects that the resistance to compression of the utility model and half wear-resisting camber tooth top metallic card clothing structure letter
Single, manufacture is easy；Half camber tooth top metallic card clothing replaces direct tooth type metallic card clothing, and then half camber tooth top is not easy to be worn, can be very big
The service life of ground extension product；The tooth top of half camber tooth top metallic card clothing is more obvious than the ability that the tooth tip of direct tooth type bears pressure
Improve be anti-pressure ability enhancing, therefore the needle tooth of half camber tooth top metallic card clothing at work because anti-pressure ability by force without it is flexible,
Lodging；The needle tooth of half camber tooth top rush tooth processing when because top it is cambered there are due to avoid due to processing equipment operate speed
Situations such as uneven on degree, is formed by error so that the phenomenon that generating needle tooth not of uniform size i.e. needle tooth is uneven, while
It effectively overcomes direct tooth type metallic card clothing and is coated on the drawback that presented poor flatness i.e. feel is bad on roller.
With reference to the accompanying drawing to the resistance to compression of the utility model and half wear-resisting camber tooth top metallic card clothing is described further.
Detailed description of the invention
Fig. 1 is the main view of the utility model
Fig. 2 is the front view of the utility model.
In figure: 1, base portion, 2, teeth portion, 3, tooth, 4, concave surface arc, 5, front flank, 6, arc top surface, 7, rear flank, 8, root portion.
Specific embodiment
As shown in Figures 1 and 2, the resistance to compression of the present embodiment and half wear-resisting camber tooth top metallic card clothing include base portion 1 and
Teeth portion 2 on base portion, the teeth portion 2 on base portion 1 are spaced substantially equidistant several teeth 3, by concave surface arc 4 between adjacent tooth 3
Connection.Tooth 3 includes front flank 5, arc top surface 6, rear flank 7 and the root portion 8 connecting with base portion 1, front flank 5 and rear flank 7
Linearly, front flank 5 is connect with 7 intersection of rear flank by arc top surface 6, arc top surface 6 it is arc-shaped and diagonally downward with the back of tooth
The round and smooth connection in face 7.The rear flank 7 of the tooth 3 of front and the front flank 5 of subsequent tooth 3 are by the round and smooth mistake of concave surface arc 6 between adjacent teeth 3
Cross connection.
Front flank 5 and 1 bottom surface of base portion are formed by angle a i.e. anterior angle, and angle a is 35 ° to 50 °, rear flank 7 and base portion 1
Bottom surface is formed by angle b i.e. relief angle, and angle b is 30 ° to 45 °.The height h of tooth 31For 2.00mm to 6.00mm, the tooth of tooth 3
The wide w in portion1For 0.05mm to 1.00 mm, the 6 radius r of arc top surface of tooth 31For 0.30mm to 0.80mm.The height h of base portion 12It is 1.20
Mm to 1.70mm, the width w of base portion 12For 0.40mm to 2.00mm；The radius r of concave surface arc 62For 0.25mm to 0.40mm.
The front flank 5 of the present embodiment is to connect in cutting wire type, while it is in cut that arc top surface 6, which is, with arc top surface 6 with rear flank 7
Wire type connection is round and smooth connection, so that the tooth top end that front flank 5, arc top surface 6 and rear flank 7 are formed by connecting is in half arc
Type, and the tooth top of half camber metallic card clothing is obviously bigger than the tooth top forced area of direct tooth type metallic card clothing, wear-resisting and anti-pressure ability
It greatly improves, greatly extends the service life of metallic card clothing, also avoid the needle tooth of metallic card clothing well at work
Because anti-pressure ability is not strong and flexible, lodge the phenomenon that；Since front flank 5 is connect with arc top surface 6 in cutting wire type and make
Half camber tooth top metal needle tooth rush tooth processing when because top it is cambered there are due to avoid due to processing equipment operate
Situations such as uneven in speed, is formed by error so that the phenomenon that generating needle tooth not of uniform size i.e. needle tooth is uneven, effectively
Ground, which overcomes, is coated on the drawback that presented poor flatness i.e. feel is bad on roller present in direct tooth type metallic card clothing.This master
If because the needle tooth of direct tooth type metallic card clothing when rushing tooth processing since front flank with rear flank is to directly intersect, not only
So that the needle tooth tip forced area of direct tooth type metallic card clothing is small, while but also direct tooth type metallic card clothing when rushing tooth processing because
The factors such as the cutter speed of service is irregular influence so that the different i.e. needle tooth size of needle tooth height is uneven.
