Abstract

The utility model mainly discloses a flat welding ring with a V-shaped notch. The flat welding ring with the V-shaped notch comprises an unsealed welding ring body, wherein a bulge part is formed on one end of the unsealed joint of the welding ring body, and a groove part is formed on the other end of the unsealed joint of the welding ring body; the bulge part extends into the groove part; a V-shaped notch is formed between the bulge part and the groove part. According to the flat welding ring with the V-shaped notch, which is disclosed by the utility model, the joint is provided with the V-shaped notch, no breaking points are formed after welding melting, and finally, the welded product is free from welding line gas leakage.

Description

A kind of flat weld-ring with v-notch

Technical field

The utility model belongs to aluminium aluminium soldering field, special relevant with a kind of flat weld-ring with v-notch.

Background technology

Automobile, air-conditioning and refrigeration industry manufacturer are well applied by the flat weld-ring welding of flux-cored wire aluminum pipe aluminium fin heat exchanger.Due to former flux-cored wire weld-ring as shown in Figure 1, weld-ring 10 is not an enclosed annular, a place forms interface 20 therein, and traditional weld-ring 10 is all parallel, as shown in Figure 2, after in welding, weld-ring is dissolved, along the direction of arrow, drop, therefore at interface 20 places, easily produce breakpoint, and cause weld seam gas leakage, in order to improve welding quality, through a large amount of development tests.Therefore in order further to improve welding quality, through a large amount of experiments, the inventor develops the flat weld-ring structure of the better aluminium flux-cored wire of welding quality, makes the effect of welding more perfect.

Utility model content

Main purpose of the present utility model is to provide a kind of flat weld-ring with v-notch, at interface, with v-notch, after welding is dissolved, can not produce breakpoint, makes the product of final welding can not cause weld seam gas leakage.

In order to achieve the above object, the utility model is achieved through the following technical solutions:

With a flat weld-ring for v-notch, comprise non-enclosed weld-ring body, the non-enclosed interface of weld-ring body, wherein one end forms jut, and one end forms concave part, and jut extend in concave part, leaves v-notch between the two.

Described jut is outside tapered V-type point body, and concave part is the V-type groove matching with jut.

Described V-type point body and V-type groove are symmetrical structure.

Described weld-ring body, its ring body cross section is flat, and the outline of flat is rectangle, and four bights of rectangle are the fillet by chamfered.

Described weld-ring body comprises surfaces of aluminum alloy-layer and is wrapped in inner welding brazing flux medicine core by aluminium alloy layer.

The cross section of described welding brazing flux medicine core is the flat identical with weld-ring body ring body cross sectional shape.

Adopt after such scheme, the utlity model has many beneficial effects:

In the utility model, adopt irregular V-structure breach, make weld-ring body when fusing, can not produce breakpoint at interface, guaranteed the weld integrity of whole weld-ring body one whole circle, can effectively solve the weld seam leak problem that traditional structure forms.Improve welding quality, can not produce gas leak phenomenon.

Accompanying drawing explanation

Fig. 1 is weld-ring body construction schematic diagram in prior art;

Fig. 2 be in Fig. 1 A-A to schematic diagram;

Fig. 3 is the structural representation of the utility model preferred embodiment;

Fig. 4 be in Fig. 3 B-B to schematic diagram.

The specific embodiment

By reference to the accompanying drawings, to the utility model, preferred embodiment is described in further details.

In the present embodiment, mainly comprise non-enclosed weld-ring body 1, because weld-ring body 1 is non-enclosed construction, therefore form a v-notch 2.The two ends of v-notch 2, wherein one end is along the circumferencial direction of weld-ring body 1 to outer process, form jut 11, the jut 11 in the present embodiment is V-type point body, and type is in spine, and the other end forms concave part 12, the present embodiment concave slot part 12 is V-type groove, and jut 11 extend in concave part 12, and both match at shape, can form splicing, retain certain gap between the two.In the present embodiment, V-type point body and V-type groove are symmetrical structure.

When the utility model is when welding, when 1 fusing of weld-ring body, along direction of arrow blanking, because v-notch 2 of the present utility model is in the seamless generation of direction of arrow projection, it is hereby ensured a complete welding ring body, do not form welding crack, improve welding quality.

In addition, in the present embodiment, the ring body cross sectional shape of welding neck collar body 1 has also carried out certain improvement, changes flat into, namely flat structure.Particularly, be that its outline is rectangle, four bights of rectangle are the fillet by chamfered.

Weld-ring body 1 comprises surfaces of aluminum alloy-layer 13, welding brazing flux medicine core 14 from outside to inside, and the material that the two adopts or raw material are all identical with existing weld-ring, but its planform is different from tradition.The shape of welding brazing flux medicine core 14 in the present embodiment is also identical with the contour shape of weld-ring body 1, just the difference of size.

Above-described embodiment is only for the inventive concept of the present utility model of explaining, but not restriction to the utility model rights protection, allly utilizes this design to carry out the change of unsubstantiality to the utility model, all should fall into protection domain of the present utility model.
