Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a guide tube for filler metal wire of a welding machine, in particular an electric arc is formed between an electrode and a welded part to heat the filler metal wire to a high enough temperature to flow. Conventionally, this method of welding was carried out as follows. For example, as soon as you are removed from the reels, #! The shape of the wire used for contacting the filler metal was used. In this method, the wire was used as an electrode to form the arc, and in other cases it was used not as an electrode.

To accurately #*: the light leakage of the filler metal wire must be guided under a suitable slope to the weld. That is, the wire must be moved cleanly along the #I tangent without twisting.

Usually, the filler metal wire is placed in a tube having a slotted hole at a suitable position for adhesion resistance, such that it enters the tube from the bare end and protrudes slightly at the ferruled end. In the bore of the tube, there is a smooth contact between the wire and the inner wall of the bore, which is prone to premature wear.
A number of actuating devices have been proposed over the years.

This offIlib@* is effective for passing current through the wire in the bath material guide tube.・Such tubes are called interlocking tubes.・Conventional tubes have several drawbacks in operation. &
Due to the arc discharge occurring within the long hole of the guide tube, the inner mtl hole and the nature of demonic contact.
I turned it into an S. 9. The conventional actuating device* has a very complicated structure and is too expensive to use.This device is entirely made of large scale, so f! It was difficult to use this type of guide tube inside a nozzle that sprays gas onto the I-layer.・Such conventional guide tubes were prone to scattering from the welded area due to the turbulent state of melting accelerated by the gas jet. Substance has accumulated. This thrown-off material causes harmful adhesion between the tube and the tip of the filler metal. Also, as the temperature warms up, metal builds up and clogs the exit of the gas nozzle, forming a bad arc, especially between the narrow side of the tube and the nozzle. Such arcs can have harmful effects, especially when operating machines with automatic arc current power systems.

According to a preferred embodiment of the present invention, a guide tube is provided which eliminates disadvantage I mentioned above and which provides a long life and a good weld burnout 11.

Summary of the present invention A summary of the industrial pipe for bath material wire of a bog welding machine, especially an electric arc/p# machine according to the present invention, is a cylindrical body provided with a long hole for guiding the wire. and an actuating device, the actuating device comprising at least one slither member movably attached to a hole provided in the wall of the guide tube, the elongated hole and the hole being mutually connected. Connect orthogonally, #i-thststs
4t is suppressed by an elastic member 1 and protrudes into the elongated hole m, so that the wire passing through the elongated hole is elastically pressed against the opposite wall of the elongated hole. Further, the #I elastic member is a six-cone compression spring consisting of a spiral spiral, and this spring is disposed in the hole within the thickness of the tube wall.

When a compression spring is compressed, a spiral spiral becomes I%.
A cylindrical shape that can be overlapped at the top.

Instead of 0@ construction, by 8 nozzles of large spirals to give a minimum compression spring length equal to the sum of the spiral-O thicknesses.
A small volute can be compressed into a single volute. Due to this conical feature, there are four pressure springs inside the hole.
In this case, a thrust door material, preferably 100 mm in diameter, is placed in the hole, and the 1/7 in. diameter is limited to within 1% ago thickness so as not to protrude from the wall of the tube. The degree of penetration of the ball into the nostril of the tube should be limited by the ball holding sheet.

In a preferred embodiment of the invention, the thrust sIt is made of electrically insulating material or is at least coated with a p1-like material. Similarly, the spring is covered with electrically insulating material. This eliminates the risk of arcing of the movable parts of the actuating device.

In the l@O preferred embodiment, the spring-receiving hole opens on the outer surface of the tube surface. The hole is made by one tube that takes out the guide tube.
Closed. The largest spiral I of the conical spring abuts one tube. 1 The tube is made to protect at least the outer 1111 side of the spinning end of the guide tube from the metal that ejects and adheres from the 8 fitting part.The lid tube also electrically insulates the guide tube. .

Therefore, the generation of secondary arcs is stopped, and
Hardened welding metal accumulates at the outlet of the gas injection nozzle and becomes sticky, or the filler metal wire sticks to the roof.

The @2041 characteristics of the guide tube for filler metal wire for welding machines, especially electric arc II welding, by Akira Hontate are that the tube is.

It is equipped with a cylindrical body having a long hole for guiding the wire, and has a hole whose 9 ohm end communicates with the long hole for guiding the front end VC through a relay f4 to prevent molten metal from adhering. to
The relay end has a rear fitting 111KjlJI attached to the cylindrical body, and a retainer 1i that covers the cylindrical body.
ii The lid tube is held inside the tube, and the lid tube is provided with a self-demarcated end, and the front end of the relay end is held within the tube.

v = thing.

Treatment material V where weld metal was accidentally attached due to the middle 11th edge
The ear enters the long hole of the guide tube and prevents it from being destroyed. Preferably, the relay end is tapered toward the tip. This tapered tip facilitates fitting into the groove 1 in the surface of the weld.

In the second embodiment, the diameter of the relay tube section at the relay end is larger than that of the seventh HD tube section, and a shoulder section is provided at the 60th point.

This shoulder is supported by a circular rim provided at the end of the lid tube.
- The copying tube part at the relay end held by the lid@0 end should move to the extent that it bends. Therefore, a relay end ttm can be formed in the center of the elongated hole of the guide tube. When an actuating device, such as a bolt, is placed inside the guide tube, the filler metal wire fits into a groove in the tube wall. Therefore, as time passes, the intermediate end of the middle 11th axis can be moved freely as shown in the figure, so the intermediate end can be installed without blocking the path of the filler metal. - In a preferred embodiment of the present invention, the orientation of the hole at the relay end is as follows.

They are made to have unequal diameters.

This prevents the filler metal wire from depositing a layer of metal particles on the 11th side of the hole.If the hole has an equal diameter OwR surface, the metal particles will adhere and the length of the relay end will be reduced. A KnDs conductive film is formed. Such conductivity O1 generates an electric arc on the inner wall of the hole at the relay end. If the holes are of non-uniform diameter like the present BA, the metal particles will adhere to the narrowest part of the hole, regardless of whether the hole tapers forward or backward. This is advantageous for such a taper hole.

The following is an explanation based on the drawings.

FIG. 1 shows a class II electric arc machine operated in either the metal active gas process (M'G) or the metal inert gas process (MIG).

This electric machine is equipped with a metal head. The lower end of the metal head (to) O is a nozzle (b), and gas fIt, (b) flows in the nozzle chaff 14-tD as shown by the arrow.

Contrary to the popular belief that this gas company uses S* technology, it is either active, inert, or O. Bottom end of nozzle (2)■
is placed on the base metal (2), and on top of that, an electrode arc- Retained.

When the weld m (g) is held at a very high temperature by the arc), the tip of the filler metal wire 18B1 gradually becomes 7% K: , is held in place by a tube known as a contact tube. A screw thread is provided on the top 1a of the pipe 4#O, which is attached in the longitudinal direction Os of this rigid pipe nozzle shaft ν pa.
Conductive support tube HK with screwed.

19, the tip of the wheel is pushed out between the two wheels. That is, the wire @8) is unwound from the reel can by the two wheels, and the long hole is pushed into the hole of the contact tube, and the tip is inserted from the end of the tube. stand out. The support tube is connected to the power supply and connected to the other controller (2).

19. Connect to base metal (B) and connect to 9 cables (To). The hole in the energized contact tube fP) is made to fit the filler metal wire. This hole, as described below,
Bring the hole into contact with the wire, guide the wire, ftp, m
When power is supplied, an introduction hole (
6) A seven-way docked chamber is provided with an inlet hole (4a passes through the head <yicv wall mt-.

A gas supply pipe is connected to supply a gas suitable for the welding technique used.The Is-shaped chamber head communicates with the nozzle chamber via a longitudinally extending hole This hole is provided in the insulating material (c), and is electrically insulated from the support tube and the main body of the head through this insulation. m is slightly tapered.

Since the tip of the tube-〇 is surrounded by nine neutralized ceramic end SWt mound holes @, from the tip of this neutralized ceramic end i60+, The tip of the lacquer wire protrudes and the arc and the melt layer are exposed to the gas flow flowing through the nozzle in the direction of the arrow.

Stripe 2 shows an electrical connection device &I used in the TIG method. The electrode wheel is arranged along the longitudinal axis of the nozzle 141, and through this nozzle 141, the gas stream is sent in the direction of the welding head in the direction shown by the arrow.

In the C arrangement, electricity is applied to the electrode and the base material 4, which causes the tip UIJ of the electric current mIl and the bathing part σ of the base material σO to
A-l is formed between 4 and 4.
It is added in the form of 5. The tip of this wire σ5 (7E9
crosses the arc in the vicinity of nine electrodes placed in the aperture of the nozzle. The filler metal wire is guided by a guide tube trowel. At the tip of this guide tube σ barrel, a neutralization section 2 (tsuknA4) is provided.

The 1s3 diagram shows a nine-cylindrical body made of conductive metal such as steel.
) is shown in the contact tube with a The contact tube (C) has an elongated hole 4 extending in the longitudinal direction and communicating with the front end (C) and the rear end. The diameter of the elongated hole is the same except for the vicinity of the rear end of the tube. Near the rear end, there is a long hole.
A much larger hole (1) is provided, followed by an inverted conical hole (2). Therefore, insertion of the filler metal wire link is facilitated.

In the direction from the rear end to the l1tr end, the following parts are formed on the cylindrical body (O): a threaded ring,
A cylindrical part (c) has two opposing flat surfaces of equal diameter so that a spanner can be caught on the pipe, and a shoulder tg1ma that joins the front cylinder S trowel. A peripheral groove is provided in the vicinity of the shoulder portion ω3 of the front cylinder portion.

Two tapered holes (E) are provided in the wall surface in a direction perpendicular to the longitudinal direction of the tube. The small diameter end of the tapered hole is in communication with the elongated hole. The large diameter end S of the tapered hole (2) opens to the outside at approximately the middle of the front cylinder part (E) between the shoulder s13 and the front end (C). The two tapered hole ends lie on the same generation line of the tube.

These taber holes receive seven balls each having a diameter slightly larger than the diameter of the ball. The balls (E) are pushed into the elongated holes Q by compression springs 197)K, respectively. This compression spring u7) is a spiral cone whose diameter is small in the portion that suppresses the ball Wt.

The large diameter S of the spiral end matches the large diameter end of the tapered hole end, and is held by a lid cylinder @ having an inner diameter approximately equal to the outer diameter of the front cylinder part. By inserting it into the rear end (102) of the front end t851t* of the cylinder body, the lid cylinder (b) becomes the front cylinder smtat. - The tube is at the appropriate position V (at some point, it is long enough so that the shoulder round and the rear end come into contact with each other. It is preferable that the size is such that it can be joined to the circle WJ portion of the cylinder body (2) without any interference.

The relay 115G is a ceramic block made of 211111 parts with different diameters. That is, the relay end 1 consists of a front cylinder part (12G), a rear cylinder part (11o), and a hole (115) having the same diameter as the elongated hole. In the pipe (b)), the relay thread 0501 has a rear surface (112). This mask (11 phantom) comes into contact with the front end surface (c) of the cylinder body (3).The rear cylinder part (UO) of the relay end 1 is arranged in the lid cylinder (2) so that it is placed inside the lid cylinder (b). ) is approximately the same diameter as the inner diameter of the

The front cylinder part (1w) has a smaller diameter than the rear cylinder part (112), and they are interleaved with each other via shoulder 5 (11). 91 is partially closed by 4o. When vhVc is fitted together, the relay end 5
The IjO front cylinder S (country) is - uniform opening 006),

Make suitable electrical contact with one side. The magnitude of the spring force applied to the ball is such that when the ball is lifted by the wire inside the ball, the ball firmly presses the wire against the long hole ring (I). Next, the wire J is passed through the relay end and held at a completely straight length at the tip.At the exit of the nozzle, the wire is placed opposite the bathing part. are doing.

Push it out in the direction of the Osumi part (lat-x).

The movement of the ball between the ball (axis-1) and the ball (SS-Z) is controlled by a conical compression spring θ7, respectively.
, will be collected. Since the spring has a conical spiral shape, the spring can wrap the spiral around part b, so a compression spring action can be performed in a very thin part as thick as the wall of the tube (spring +97) itself. Although diagram VC is not shown, the compressed length C) and the stretched length q are shown.

Since there is a difference between them, it can be seen that the absolute length is relatively small.

There, the tRO outer diameter (, A is 6cm), the wire diameter (b

Therefore, even if a conical spring that cannot be pressurized by d% is compressed at 3-, it will be compressed from 0.4 ms to 0.6-. This arrangement makes the compression spring substantially flat. That is, each spiral is placed in a larger spiral tII:D#Pvc

In this example, if the diameter of the wire is 0.25μ,
The spring has a volute of 34a, the smallest volute contains an inner diameter of 1, and the outer diameter of the volute is 13-. 0
That is, the wall surface of the cylindrical body in the lid tube (2) is equipped with balls and springs (97 )
and can be placed. Tapered holes t# may be formed using a conical drill bit. Such devices are not made to protrude under wall thickness O pipes of 1.8- or less.・Properties of metal? , s Depending on the size of the M wire wire, it may be one ball. This is particularly necessary in the case of soft metals such as aluminum and its alloys. As shown in Figure 3, you can use a ball or two to make six circles, or even more.

Working! ! One of the major advantages of this system is that it provides good electrical contact between the filler metal wire and the slotted hole in the tube, even though the tube wears out during use. is to be maintained. In particular, arcing within the tube can be prevented. An arc like this makes a hole.

If two balls are used as shown, they will burn out and degrade the electrical contact, creating more arcs between the wire and the tube, along the generator line of the tube. 1 & the contact area is widened, thereby reducing friction, abrasion and abrasion.

The ball may be made of electrically insulating material or preferably of a hard material. For example, the ball may be made of hardened glass, ceramic, ruby, or sapphire. ? I! The tertiary material reduces the tendency for arcing within the contact tube. Although the ruby ball is very lllbiliii, it is very hard, increasing its lifespan.

Spring @ is made of fire-resistant stainless steel that can withstand high temperatures, Inconel (Iho@oml)% or Honeymonik (ni-mon-n).
iak) Preferably made of alloy.

Next, these O surfaces are preferably coated with chromium dioxide or the like through pistol @wrinkling or heat treatment so as to be electrically insulated. This reduces the risk of arcing within the tube, thereby changing the nature and life of the sickle. In conventional o'lf/c, in addition to corrosion effects, parasitic electrical arcs interfere with the smooth movement of the wire, resulting in non-uniform f# junctions.

The lid tube @ is preferably made of fire-resistant steel that can withstand OII degrees at 1100 tel' t, for example. In this embodiment, both the top and bottom of the lid tube are completely covered with an electrically insulating material such as chromium dioxide in the same manner as in the case of the spring.

As a result, in Fig. 1, welding S (t) during welding
Even when metal droplets splashed from the nozzle enter the nozzle, they are prevented from adhering to the t% cover tube 2). Therefore, solids do not accumulate in the pipe □□□, and the flow path of the gas blown out from the nozzle is partially % * IF.
Parasitic arcs between the contact wμsj and the nozzle pitch are avoided. At 7ζ, the main body of the cylindrical body is insulated by the cover tube 4, and the main body placed on the buttock is heated (K).The nozzle (2) itself is preferably coated with ceramic.The nozzle is made of copper or brass. If it is made of metal such as [CHPOLAN8KY
) by using a pistol device, etc.
It is preferable that the coating is performed by spraying ceramic powder through a nozzle VC. This coating covers the inside and outside of the nozzle and the inlet O.
It should be a shame department. This safe coating protects and electrically insulates against molten metal splashes from the bathtub.
Therefore, the droplets do not adhere to the coating surface of the nozzle.

In an embodiment not shown, the location 0i)lJt! The front end of the cylindrical body is covered by a front wall surface having a hole through which the end of the wire can be inserted. The lid tube (9) is covered with a leather-like material made of ivy. 1llii

The u point is as follows. That is, even in the event of an accident that obstructs the pre-flooding of the additive wire, the molten metal rising up the contact tube will not reach the ceramic of relay 46f).
It is impossible to cause krIIps, so it should not adhere.

Comparatively, the end of the cap tube 4 is thus protected against the extremely high degeneracy that would otherwise be experienced in the absence of intermediate degeneracy. 1 Seki), the axis is long,
Or it has become Kuteba. The relay end (1) is attached to the front end of the cylindrical body (2) using the cover pipe (2) of the holder.

The rear tube part (melon) is connected to the large diameter rear end of the tapered cocoon tube part (tS*) via the shoulder s (l line). Spinning Ili
The length of part (l) is lO-. The shoulder s (1 brocade) is in contact with the curved rim (1G4) of the lid tube (9).

The filler metal wire r18+ passes through the hole and fits into the long hole. The tip g@ of the wire) is #Jt
It protrudes from the small diameter tip of section II4 (m).

The shape of the relay M (is) is inside the base material (1a) (16@
) (particularly suitable when bathing at the bottom of D. Relay It
(1110) prevents the bottom of the filler metal wire from melting at the end of the contact tube itself (metal buildup at the bottom of the groove). This tapered groove promotes the flow of gas from the nozzle to the bottom of the bath (16G). In the embodiment shown in Fig. 3, the lid tube 01OQ is circumference m
It is locked to the main body of the cylindrical body (2) by three points provided on 5a1. Therefore, we hold a spring in place in the tapered hole, hold the relay end mt at the front end of the barrel body

The relay end [1■] has a cylindrical shape and is provided with a large diameter portion (C1 shaft) that is larger than the rear cylinder portion (LOZ). Large diameter part (1m)

t, bring it into contact with the front end of the cylindrical body.

The diameter of the rear cylinder part (202) is slightly smaller than the inner diameter of the lid cylinder (9). Therefore, a small cavity (2Gg) is provided.

Similarly, the outer diameter of the front tube 5 (ZQ4) at the relay end is the same as that of the lid tube (2
) is also slightly smaller than the inner diameter of the aperture (105) at the end.

Therefore, the relay end (200) can move vertically inside the lid tube and hold the relay end flat. Despite the wear that occurs on the guide tube, such an arrangement provides better retention of the filler wire due to the narrow end.
