Description

[Background Art] [0002] A coated device of brazing ring fused-flux

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a melt coating apparatus, and more particularly, to a melt coating apparatus for a brazing filler metal for coating a flux on a brazing filler metal, .
Hereinafter, the brazing ring refers to a filler having a ring-shaped cross section which is supplied onto the joint portion of the base material during brazing.

Generally, brazing widely used in the household appliance industry, tool industry, automobile, aerospace field, etc., has a temperature range from a working temperature of 450 ° C or higher to a melting point temperature of a base metal to be bonded Is a bonding technique used to bond two base materials by applying flux, filler and heat to the base material, but not to deform the base material in the course of the work.

In order to prevent the oxidation of the molten metal and the base material, it is necessary to coat the surface with a material that can chemically protect the metal (base material) to prevent oxidation of flux and flux flux.

Silver, copper, zinc, lead, etc. are used as the filler used to bond the two base materials while being melted by heat at the time of brazing in consideration of the type of base material, melting point, base material and affinity.

A joint gap is required for the portion to be welded to the joint portion during brazing, and the amount of the filler that can fill the space is calculated to set the amount of the filler.

The amount of the filler material can not be accurately controlled in the conventional manual work, and therefore, the required filler material with respect to the quantity of the product to be brazed is not necessarily balanced in quantity at all times.

Further, in the brazing process, it is inconvenient to perform brazing by a series of repetitive operations in which flux is applied after heating the base material to be joined with the torch, and then molten material is contacted to the base material to be joined.

On the other hand, in terms of the environment, "torch brazing" and "automated high frequency brazing" are gradually diffused, but the method of applying the filler and the welding material is the same as that of the conventional torch brazing, It is a fact that they are supplying petrochemicals.

Although the automatic line of torch brazing is also used, this method also automatically applies the welding material to the base material, and when the temperature of the base material is heated by the automated torch, the brazing material is supplied by the material supply device.

In automated torch brazing and high frequency brazing processes, productivity is deteriorated by the time required for separately supplying the filler and the wood material, and since a paste material is directly used, a large amount of fume and foreign matter are scattered during the melting process, And devices.

Particularly, in the high frequency brazing, there is a problem that the bubbles generated by melting the paste in the paste state are adsorbed to the high frequency coil, and the scattered / adsorbed material (components of the flux) must be removed.

There is a way to use gas flux in vaporized state without torch brazing. However, in order to comply with industrial safety / health law, which is strengthening work environment and safety management, .

Therefore, in order to improve the industrial site to an environment friendly work site, there is a desperate need for an integrated product in which not only a working method but also a molten coating and a filler are combined.

In order to solve the above-mentioned problem in the high-frequency brazing which is an eco-friendly working method, a monolithic product in which the surface of the consumable material is coated with a solvent is required.

It is impossible to solve the problem that the scattered dust and bubbles generated by the melting of the molten metal during the brazing operation when the molten metal is applied by the conventional method can not be solved. Therefore, the "monolithic molten metal" coated in the state just before the molten metal rises to the activation temperature, .

In the conventional working method described above, waste of the consumable material (raw material) is increased, the price of the finished product is increased, and an additional preventive facility for environmental management is required, so that the management cost for managing the same also increases the cost cost .

In the manual work method in which the torch is heated by separately injecting the abrasive and the flux during brazing, the production speed is slowed and the productivity is significantly lowered.

A publication of No. 10-2009-21435 (published on Mar. 4, 2009) discloses a brazing welding material coating method of an aluminum alloy product.

The embodiments of the present disclosure can prevent the contamination of the working environment and the equipment due to the scattered dust and fumes generated by melting of the brazing material at the brazing time by coating the brazing filler metal with fused flux To a powdered molten coating apparatus of a brazing ring.

The embodiment of the present invention uses an integrated melt coated flux ring which combines the proper weight of the meltable material and the appropriate amount of the meltable material necessary for the brazing to prevent the material from being wasted during brazing and shorten the work flow To thereby improve the productivity of the brazing ring.

To achieve these and other objects and in accordance with the present disclosure,

frame;

A turntable repeatedly rotating and stopping at an arbitrary angle by a first driving unit at a center of the frame;

A filler material hopper mounted on the frame, the filler material hopper including a filler material having an arbitrary shape and a travel path for aligning and moving the filler material moved from the filler hopper;

A rotary pin disposed on the turntable at an equal interval in the circumferential direction and rotatably rotated in one direction by a second driving unit, the rotary pin being detachably mounted on the upper end of the rotary shaft;

A first clamper for gripping a single filler material at the tip end of the movement path and turning the direction of the filler material to place the filler material on the rotation pin;

A preheating unit for preheating the surface of the filler material to a predetermined temperature by a torch so that the molten material is melted and adsorbed on the surface of the filler material seated on the rotating pin;

A blade spraying part for spraying the powdery material discharged from the molten material hopper to the preheated consumable material on the rotary pin through a nozzle;

A first heating unit for heating the molten material sprayed on the sparing material on the rotating pin by a torch in a semi-molten state;

A latent heat fusing part for compensating for a time for melting the filler into the molten coating layer by the latent heat of the filler and the melting material;

And a second clamper for converting the direction of the gripping material on the rotating pin immediately before the molten coating layer of the smearing agent completely coagulates and then returning the collected material to the collection container to recover the molten coating material. .

According to the embodiment of the present specification having the above-described configuration, the following advantages are obtained.

Since the generation of dust and fumes scattered due to melting of the welding material during brazing is removed beforehand in the process of coating the melting material on the smear material, the generation of fume and scattered dust is reduced more than the working process using the welding material separately. It is possible to protect the health, prevent the equipment from being contaminated, and extend the service life.

In addition, by providing an integrated melt flux coating ring that combines the optimum weight of the required material and the amount of the flux required on the joint part during brazing, it is possible to prevent the waste of the raw material (brazing material) during brazing, thereby reducing the cost cost, (In the past, it is necessary for the worker in brazing to perform a series of repeated work processes such as base material heating, flux application, base material and material heating, Consuming unnecessary time).

In addition, when the shape and mass of the filler required for brazing are set, the brazing operation can be carried out without regard to the work place and the time, because a product obtained by melting and coating the melt on the surface of the filler is carried There is inconvenience in carrying bulky filler and wood during brazing).

Further, when the brazing material is dried, a work process in which it is diluted with water and stirred is unnecessary.

In addition, by modifying the amount of the filler and the flux necessary for the brazing portion into an integral form, excessive consumption of the flux and the filler can be prevented.

In addition, when the conventional pulp is used in a powder state or a paste state, the amount of the pulp used can be reduced by about 10% of the weight of the pulp added.

In addition, since the temperature (350 to 400 캜) at which the molten material is melted and coated at the melting temperature is lower than the activation temperature of the molten material (500 to 600 캜) and the temperature at which the molten material begins to melt again (280 to 300 캜) The time can be shortened in comparison with the conventional working method (the work process in which the welding material is used separately is less in workability due to a long time until the welding material melts).

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, examples of use of a powder coating melt coating apparatus of a brazing ring according to an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

1 to 9, when the drive motor 46 mounted below the upper plate of the frame 10 is rotated, the drive shaft 48 connected to the drive motor 46 is rotated, The drive roller 47 in the form of a pulley, which is mounted as much as possible, is rotated.

Shaped drive belt 53 with its outer side surface in contact with the drive roller 47 is rotated by the rotation of the drive roller 47 so that the frame 10 can be rotated at an arbitrary distance and at an arbitrary angle with the drive shaft 48, The first driven shaft 50 and the second driven shaft 51, which are rotatably mounted on the rotating shaft 51, rotate simultaneously. Therefore, the idler 49 rotatably mounted on the upper ends of the first driven shaft 50 and the second driven shaft 51 rotates, respectively.

That is, by the rotation of the drive belt 53 interlocked at the time of driving the drive motor 46, the drive roller 47 of the drive shaft 48 and the idler 51 of the first driven shaft 50 and the second driven shaft 51, (49) rotate at the same time.

At the same time, when the drive belt 53 is rotated, the driven roller 52 (eight of which are used in the figure) which is in close contact with the inner surface of the drive belt 53 and is rotatably mounted at the lower end of the rotation pin 18 rotates So that each of the rotation pins 18 of the turntable 12 can be rotated in one direction.

The turntable 12 repeats the operation of rotating and stopping at an arbitrary angle by the first driving portion 11 (for example, a step motor can be used) provided centrally under the turntable 12. [ That is, when the turntable 12 is rotated by the first driving unit 11, each of the rotation pins 18 rotates in one direction by driving the second driving unit 17. [

The filler materials 13 accommodated in the filler material hopper 14 mounted on one side of the frame 10 are discharged individually from the filler material hopper 14 by the vibration means (not shown) (For example, in the form of a two-stage coil spring), which is discharged from the rotary shaft 15, is continuously moved to the movement passage 15 by arranging the small diameter portion upward and the large diameter portion to be positioned below.

At this time, it is possible to prevent the sparkling material 13, which has been moved to the tip of the movement passage 15, from falling by the stopper 34 of the plate spring type mounted on the tip of the movement passage 15. Even when the fugitive material 13 discharged from the excipient hopper 14 is continuously moved to the moving passage 15, the stopper 34 mounted on the leading end of the moving passage 15 temporarily stops the movement of the sparkling material 13 It stops.

Therefore, the fugitive material 13 moved to the tip of the moving passage 15 is gripped by the clamp of the first clamper 19 and then is turned toward the turntable 12. At this time, the first clamper 19 holding the single fugitive material 13 is lowered to an arbitrary height by the driving means at the time of changing direction so that the fugitive material 13 can be seated on the rotary pin 18 of the turntable 12 do.

At this time, when the filler material 13 is placed on the rotary pin 18, the rotation of the turntable 12 is temporarily stopped because the driving of the first drive unit 11 is switched off, Is continuously rotated in one direction by the driving of the second driving portion 17. [

It is possible to repeat the operation of placing the filler material 13 on the rotary pin 18 of the turntable 12 by the first clamper 19 which grips the filler material 13 from the moving passage 15 as described above .

The filler material 13 seated on the rotary pin 18 is moved to the preheating section 21 as the turntable 12 is rotated at an arbitrary angle. This makes it possible to preheat the filler material 13 of the rotary pin 18 by the torch 20 of the preheating section 21 which maintains a certain distance and arbitrary temperature from the filler material 13 of the rotary pin 18.

The torch temperature of the preheating section 21 is 300 to 320 DEG C and the torch temperature of the second heating section 29 is 280 to 300 DEG C. [

That is, when the molten material having a melting point of about 320 DEG C is melted at a high temperature at a time by the torch of the preheating section 21, the molten material can flow down along the surface of the molten material 13, It is preheated so as to be melted.

On the other hand, the heat source of the second heating unit 29 is further heated so that it can be transferred to the interior of the semi-molten state of the molten metal 13.

In the embodiment of the present invention, the molten material to be melt-coated on the meltable material 13 starts melting at about 320 DEG C in the initial powder state, but when the primary molten material is re-melted after solidification, melting starts at 280 to 300 DEG C .

Therefore, even in the case where a lower heat source is supplied in the secondary heating region, the molten molten material on the surface of the molten material 13 is less flowable at low temperatures, and the molten material does not flow down from the molten material 13. In addition, since the rotary pin 18 on which the fugitive material 13 is mounted rotates with respect to the turntable 12, it is possible to suppress the flow of the flux from the sparkling material 13.

Due to the amount of heat remaining in the sparkling material 13 and the amount of heat remaining in the sparkling material 13 due to the heating by the first heating part 25 and the second heating part 29 by secondary heating of the fugitive material 13, The fused fusing material remaining in the molten coating layer in a small amount is melted by the latent heat in the latent heat melting section 26, and immediately after melting, solidification and cooling of the melt-coated fused material in the fusing material 13 are started.

When the recovered container 13 is rapidly cooled, the melt-coated material is peeled off from the meltable material 13 in accordance with the expansion coefficient difference of the meltable material 13 and the meltable material 13 in the meltable material 13 .

At this time, the cooling member (not shown) provided in the recovery container 27 keeps the temperature at a certain temperature so as to prevent the molten material melt-coated on the molten material 13 from being remelted, .

That is, the molten material solidified in the molten finishing material 13 is weakened by thermal shock, so that peeling of the molten material may occur when the molten material 13 is rapidly cooled.

At this time, when the metal is gradually cooled to a temperature at which the metal is completely cooled, the viscosity of the molten metal can be maintained while the metal is absorbed while the metal is cooled to the atmospheric temperature.

As shown in [Table 1] below, when the wood is used in the powder state (or paste state) and when the wood is melted, it is possible to reduce the amount of the wood by about 10% of the weight of the input wood.

Powdered wood (g) The molten wood (g) Weight loss ratio (%) 2.0 1.82 9.0 4.0 3.56 11.0 6.0 5.40 10.0

The filler material 13 preheated by the torch 20 of the preheating section 21 after being mounted on the rotary pin 18 is moved to the excrement material spraying section 24 as the turntable 12 is rotated at an arbitrary angle. As a result, the powdery powder in the powder state sprayed from the spraying nozzle 24 through the spraying nozzle 23 is sprayed onto the sparkling material 13 of the rotating pin 18.

The air pressure for spraying the molten metal to the filler material 13 of the rotary pin 18 by the spray nozzle 23 in the sprayer section 24 can be supplied within the range of 1 kPa to 10 kPa.

The molten material stored in the container 30 of the molten material spraying section 24 is maintained at a particle size of about 200 mesh. When the particle size of the molten material is about 300 mesh, the molten material discharged from the container 30 is transported toward the injection nozzle 23 A dryer for removing moisture from the air line may be installed.

When the air pressure for spraying the molten material discharged from the container 30 of the molten material injecting section 24 exceeds 10 kpa, the injection state of the molten material to the molten material 13 is favorable, The temperature of the preheated fusible material 13 may be lowered due to a rapid flow of air, which may hinder the heat absorption of the fusing material.

On the other hand, when the air pressure for spraying the molten metal to the molten metal 13 is lower than 1 kpa, the molten metal is not properly sprayed onto the molten metal 13 of the pivot pin 18, so that defective products may be generated during molten coating of the molten metal.

The filler material 13 of the rotary pin 18 to which the molten material is adsorbed is moved to the first heating section 25 as the turntable 12 is rotated at an arbitrary angle. As a result, the molten material injected into the filler material 13 is heated to a semi-molten state by the torch 20 of the first heating unit 25. [

The filler 13 in which the molten metal is adsorbed by the torch 20 of the first heating section 25 in a semi-molten state is moved to the latent heat melting section 26 as the turntable 12 is rotated at an arbitrary angle. This compensates for the time for melting the inside of the molten coating layer of the filler 13 by the latent heat of the filler 13 and the molten solder.

The filler material 13 melted to the inside of the molten coating layer of the filler material 13 by the latent heat of the latent heat melting section 26 is moved to the second heating section 29 as the turntable 12 is rotated at an arbitrary angle. The molten metal of the fusing material 13 is not overheated by the torch 20 of the second heating unit 29 so that melting of the molten metal 13 passing through the latent heat melting unit 26 can be continued And then reheated.

The filler material 13 which has been heated again by the torch 20 of the second heating section 29 is moved to the second clamper 28 as the turntable 12 is rotated at an arbitrary angle. The gripping member 13 of the rotary pin 18 is gripped by the grip of the second clamper 28 and then is turned in the direction away from the turntable 12 and the second clamper 28 is unclamped, The recovered canister 13 is recovered to the recovery container 27.

At this time, when the molten coating layer of the fusing material 13 of the rotating pin 18 is completely cooled, the rotating fins 18 rotating along the turntable 12 and the molten steel impregnated between the fusing materials 13 are fixed, The spark plug 13 can not be recovered from the pin 18.

Therefore, immediately before the molten coating layer of the filler material 13 seated on the rotary pin 18 is completely solidified, the filler material 13 is recovered from the rotary pin 18 by clamping and changing the direction of the second clamper 28 So that it can be moved to the collection container 27.

As described above, according to the powder coating melt coating apparatus of the brazing ring according to the embodiment of the present invention,

The filler material 13 at the leading end of the travel passage 15 is gripped by the turntable 12 as the filler material 13 aligned to maintain a specific posture while being discharged from the filler hopper 14 is continuously moved to the travel passage 15. [ To the rotation pin (18)
