Abstract
The utility model provides a thin wall bores and encircles with lamellar brazing filler metal which characterized in that: the brazing filler metal ring is annular flaky texture, and thickness is 0.1~3mm, the ring width of brazing filler metal ring is 2~5mm, and thickness is less than 18 of ring width, just is in be provided with the through -hole or the blind hole of a plurality of equipartitions on the brazing filler metal ring. The utility model discloses form the part that does not need the welding material among the weld assembly and dodge the part, can practice thrift the brazing filler metal, reduce manufacturing cost. Thin wall bores and encircles with lamellar brazing filler metal produces simple process, and easily mass production has advantages such as convenient assembling, production efficiency height, convenient to use, be an excellent performance, low cost's novel brazing filler metal ring, but the wide application is brazed in large -scale disc, drum thin walled structure.
Description
Technical field
The utility model relates to a kind of solder ring, and particularly the laminar solder ring of a kind of thin-walled drill, belongs to Novel welding material field.
Background technology
The traditional soldering processes of ring-type thin drilling bit are that operator is stained with brazing flux soldering work piece with strip solder or is placed on the welded position of drill bit in advance after being stained with brazing flux with fan-shaped flake solder, and this kind of soldering processes complexity, production efficiency are low.At present, fan-shaped flake solder main production is according to welded planform, presses out in large area thin slice solder upper punch, and the subject matter of this production technology is that stock utilization is low, and waste resource, the especially manufacture of large scale solder ring, waste more serious.
Utility model content
The purpose of this utility model provide for weak point existing in above-mentioned prior art just a kind of preparation method simple, be easy to mass production, heavy duty disc with low cost, the laminar solder ring of cylinder thin-wall construction.
The purpose of this utility model realizes by following technique measures:
Thin-walled drill of the present utility model laminar solder ring flaky texture ringwise, thickness is 0.1 ~ 3mm; The ring width of described solder ring is 2 ~ 5mm, and thickness is less than 1/8 of ring width, and is provided with multiple uniform through hole or blind hole on described solder ring.
The shape that the utility model is arranged on through hole on solder ring or blind hole such as is at circle, the polygon of regular figure, or the irregular curve closed or the irregular closed figure be made up of straight line and curve.
The beneficial effects of the utility model are as follows:
Thin-walled drill described in the utility model is simple by laminar solder ring production technology, is easy to mass production; Described solder ring has multiple uniform through hole or blind hole, can dodge part, can save solder, reduce manufacturing cost, have good economic benefit and huge social benefit not needing the part of welding material to be formed in welding assembly; Blind hole also can be used to store solder flux, realize brazing flux convenient, fast, quantitative, add in advance efficiently, directly can carry out soldering continuously, without the need to adding brazing flux in addition, have easy to assembly, production efficiency is high, the advantage such as easy to use, be a kind of function admirable, novel solder ring with low cost, heavy duty disc, the soldering of cylinder thin-wall construction can be widely used in.
Accompanying drawing explanation
Fig. 1 is the solder ring schematic diagram in the closed figure hole with the rule be made up of straight line and camber line.
Fig. 2 is the solder ring schematic diagram with scallop hole.

Detailed description of the invention
The utility model is further described below with reference to embodiment (accompanying drawing):
As shown in Figure 1, 2, 3, thin-walled drill of the present utility model laminar solder ring flaky texture ringwise, thickness is 0.1 ~ 3mm; The ring width of described solder ring is 2 ~ 5mm, and thickness is less than 1/8 of ring width, and is provided with multiple uniform through hole or blind hole on described solder ring.
The shape that the utility model is arranged on through hole on solder ring or blind hole such as is at circle, the polygon of regular figure, or the irregular curve closed or the irregular closed figure be made up of straight line and curve.
Embodiment 1:
Preparation method's step of this embodiment is as follows: a) silver, copper, zinc and rare earth prepared in proportion and carry out melting, (alloying component is: the Ag of 44% ~ 46% to be cast into the bar-shaped BAg45Cu30Zn25 solder ingot casting of Φ 50mm, the Zn of 24% ~ 26%, the rare earth of 0.01% ~ 0.025%, all the other are Cu), cut rising head then ladle barrow is pruned descale stand-by; B) solder extrusion equipment system is warming up to 460 DEG C, ingot casting after turning scale removal is placed in preheating in Muffle furnace, and preheat temperature is 470 DEG C, preheated ingot casting is put into the mould cylinder of extrusion equipment, be squeezed into the solder wire of Φ 1.1mm, and be drawn to Φ 0.75mm silver solder silk; C) solder wire diluted acid good for drawing is cleaned, and Passivation Treatment, put into the charging tray of milling train after cleaning, solder wire is rolled into the flat strip brazing material of 0.2mm × 2mm; D) by vertical for flat strip brazing material around (axis perpendicular of the plane that the long limit of bandlet and minor face are formed and cylindrical die) at diameter be 80mm cylindrical die on; E) the flat strip brazing material be wrapped on cylindrical die is cut off, form the laminar solder ring of band fracture.
Claims (2)
1. the laminar solder ring of thin-walled drill, is characterized in that: described solder ring flaky texture ringwise, and thickness is 0.1 ~ 3mm; The ring width of described solder ring is 2 ~ 5mm, and thickness is less than 1/8 of ring width, and is provided with multiple uniform through hole or blind hole on described solder ring.
2. the laminar solder ring of thin-walled drill according to claim 1, it is characterized in that: the shape being arranged on through hole on solder ring or blind hole such as is at circle, the polygon of regular figure, or the irregular curve closed or the irregular closed figure be made up of straight line and curve.
