Abstract

The utility model relates to a transverse machine weaving needle which comprises a needle tip, a needle body, a needle tail and a leaf spring. The needle tip, the needle body and the needle tail are integrally connected. The front end of the needle tip is provided with a needle hook, a needle latch used for being combined with the needle hook so as to form a closed ring and a first containing groove used for containing the needle latch. The needle latch is in pivot joint with the first containing groove through a rotary shaft. A step is arranged on the connecting portion of the needle tip and the needle body. An installation groove is formed in the side wall of the needle body. The tail portion of the leaf spring is installed in the installation groove through a pin. A second containing groove used for containing the heat portion of the leaf spring and a groove are formed in the side wall of the needle tip. The heat portion of the leaf spring is located in the second containing groove. An annular opening is formed by the leaf spring and the groove. A notch is formed in the connecting portion of the needle tail and the needle body. An arc groove is formed in the side wall of the needle tail. Groove bodies extending inwards are formed in the top and the bottom of the needle body respectively. The service lift of the transverse machine weaving needle can be prolonged.

Description

Cross weaving needle

Technical field

This area relates to textile machine, is specifically related to cross weaving needle.

Background technology

Cross weaving needle is a kind of loop-forming element that metal material is made, in lopping braiding process, be subject to all the time the effect of the active force (load) of alternation, the prototype structure of cross weaving needle can constantly change, its average brute force is little by little reduced, powerful probability distribution spreads gradually, and through accumulation for a long time, fracture, inefficacy and the damage that causes cross weaving needle is so-called cross weaving needle fatigue damage.First and the fatigue strength breakoff phenomenon of metal material always appears at the weakest link, or there is crackle in the concentrated position of stress, and crack-opening subsequently, until damage.

From structure and the course of work thereof of cross weaving needle, can find, the needle body of cross weaving needle is subject to alternate stress effect, be easy to stress concentrate cause fatigue strength destroy.On this position, sectional area is smaller, and geometric shape has certain variation, and is retaining the impact of residual stress in the process such as needle latch abatement, syringe needle bending.

In actual production, cross weaving needle also mostly occurred at this position because fatigue loses efficacy, and caused the phenomenons such as pinhock distortion, affected production efficiency.More existing cross weaving needles are because the design of cross section is unreasonable or weight is excessive, make the elasticity of cross weaving needle poor, the intrinsic frequency of cross weaving needle is larger, when the impact that is subject to triangle, larger impulsive force can be produced, thereby the reduction in service life of cross weaving needle and the decline of production efficiency can be caused.

Utility model content

The purpose of this utility model is to propose a kind of cross weaving needle, and it can solve short problem in service life.

In order to achieve the above object, the technical scheme that the utility model adopts is as follows:

Cross weaving needle, it comprises syringe needle, the needle body, backshank and spring leaf, the one-body molded connection of syringe needle, the needle body and backshank; The leading section of syringe needle is provided with pinhock, for engaging with pinhock, forms the needle latch of closed-loop and for accommodating the first accepting groove of needle latch, needle latch is by a rotating shaft and described the first accepting groove pivot joint; The junction of syringe needle and the needle body is provided with a step; The sidewall of the needle body is provided with a mounting groove, the afterbody of described spring leaf is arranged in described mounting groove by a pin, the sidewall of described syringe needle is provided with one for accommodating the second accepting groove and a groove of head of spring leaf, the head of described spring leaf is positioned at described the second accepting groove, and spring leaf and described groove form an annular mouth; The junction of backshank and the needle body is provided with a breach, and the sidewall of described backshank is provided with a deep-slotted chip breaker; The top of the described needle body and the bottom cell body that extended internally respectively.

Preferably, the sidewall of described mounting groove is provided with the catch for the afterbody of stationary spring.

Preferably, the angle of described backshank and the needle body is 5-10 °.

Preferably, in order to improve elasticity, the cross section of described cell body is parabolic shape.

The utlity model has following beneficial effect:

Can effectively reduce cross weaving needle suffered impact strength of when work, slow down the fatigue damage of cross weaving needle, thereby extend the service life of cross weaving needle.

Accompanying drawing explanation

Fig. 1 is the structural representation of the cross weaving needle of the utility model preferred embodiment;

Fig. 2 is the A-A line cutaway view of Fig. 1.

The specific embodiment

Below, by reference to the accompanying drawings and the specific embodiment, the utility model is described further:

As depicted in figs. 1 and 2, a kind of cross weaving needle, it comprises syringe needle 14, the needle body 2, backshank 3 and spring leaf 8, syringe needle 14, the needle body 2 and the one-body molded connection of backshank 3.

The leading section of syringe needle 14 is provided with pinhock 4, for engaging with pinhock 4, forms the needle latch 5 of closed-loop and for accommodating first accepting groove (figure do not look) of needle latch 5, needle latch 5 is by a rotating shaft 6 and described the first accepting groove pivot joint.

Syringe needle 14 is provided with a step 10 with the junction of the needle body 2.The sidewall of the needle body 2 is provided with a mounting groove 11, the afterbody 82 of described spring leaf 8 is arranged in described mounting groove 11 by a pin 12, the sidewall of described syringe needle 14 is provided with one for accommodating the second accepting groove 7 and a groove 9 of head 81 of spring leaf 8, the head 81 of described spring leaf 8 is positioned at described the second accepting groove 7, and spring leaf 8 forms an annular mouth with described groove 9.

The junction of backshank 3 and the needle body 2 is provided with a breach 17, and the sidewall of described backshank 3 is provided with a deep-slotted chip breaker 18; The top of the described needle body 2 and bottom extended internally respectively cell body 15, cell body 16.Described backshank 3 is 5-10 ° with the angle of the needle body 2.The cross section of described cell body 15, cell body 16 is parabolic shape.
