Description

mig automatic torch nozzle replacement system

The present invention relates to a MIG torch cooling device, and more particularly, to a water-cooled automatic torch nozzle replacement system.

MIG welding (Metal inect gas welding) is a method of welding a consumable wire electrode (filler material) by welding it at a constant speed to generate an arc between the base material and the filler metal, and then melt by the arc heat and transfer to the molten area through the arc column. In order to prevent consumable electrodes and foreign substances in the air from the gun, a protective gas is supplied together to block the air to protect the arc and the molten part. MIG welding is easy to operate, has a fast welding speed, does not require post-welding treatment because there is no slag and minimizes spatter, has good welding efficiency, can perform full-position welding, has large penetration, and has high current density. In addition, as this method uses high heat, most water-cooled cooling methods using water are used. As a prior art, there is Patent Registration No. 10-1742298 "torch nottle for MIG welding".

In the case of a conventional water-cooled Mig torch nozzle, two problems arise when replacing the nozzle because it is fixed simply by connecting a female screw and a male screw. First, when replacing the nozzle, since the cooling water in the MIG torch is not virtuously circulated, the cooling water may be discharged separately. Second, as the operation of the machine must be temporarily stopped (OFF), the continuous operation becomes impossible, resulting in operation delay and reduced efficiency.

A circulation groove is formed in the lower part of the first stage of the nozzle unit in a circular shape, a cooling water guide groove is provided in the longitudinal direction on the inner diameter of the nozzle unit, a circulation connector is formed at the end of the cooling water guide groove, and the circulation connector is in contact with the body connection hole of the body part, and the body A connecting cylinder provided with a first through-hole at the end of the connecting hole; a movable member that faces and is provided with a "┐"-shaped vertical flow part on the front side to be interviewed with the first through-hole and a "┌"-shaped vertical flow part is formed on the rear surface, respectively; and an elastic member to be interviewed on the rear surface of the "┌"-shaped vertical flow part; and

In addition, an upper through-hole is formed to face the bottom of the "┐"-shaped vertical flow part, a lower through-hole is provided opposite the upper through-hole, and O-ring mounting grooves are provided on the front and back surfaces of the upper and lower through-holes, respectively. and a cover member having a second through-hole formed in the inner diameter;

In addition, the inner diameter of the cover member is provided with a central arc-shaped portion, a front oval portion 61-2 is provided protruding from the front of the central arc-shaped portion, and a front portion having a front inner inlet portion formed on the rear surface; and

An upper oval portion is provided on the upper portion of the front inner inlet, and an upper surface portion having an upper inner portion is provided on the front of the upper oval portion;

a rear portion formed by extending a horizontal horizontal portion on the rear surface of the front portion in a straight line; and

A first bottom oval part and a second bottom oval part are provided on the bottom surface of the front part, and a bottom part formed by extending a central arc-shaped part between the first bottom oval part and the second bottom oval part; consists of.

In the case of the conventional product, the cooling water was discharged when replacing the nozzle and the machine was temporarily stopped. It has the effect of efficient cooling and minimizing work delay.

When the coolant is circulated as described above, the coolant is preheated and discharged, as described above, the coolant guide groove 102 - the first circulation connector 103 - the body connection hole 11 - the first through hole 21 - "┐" shape The same order as that of the vertical flow part 31 is the same, but the cooling water from the "┐"-shaped vertical flow part 31 is discharged to the discharge hole 202 through the rear horizontal part 63-1 of the control unit 70. do.

When the nozzle unit 100 is separated, the moving member 30 that was interviewed on the circular cylinder 22 loses its binding force as shown in the attached FIG. Due to the elasticity of (40), the movable member 30 moves to the front side, the "┐"-shaped vertical flow part 31 is not connected, and the "┌"-shaped vertical flow part 32 of the intermediate member 300 is It moves through the through hole 301 .

The cooling water that has moved as described above is blocked by the fixing member 41 and moves to the through hole 301 of the intermediate member 300 again. The cooling water passing through the central arc-shaped part 61-1 is discharged to the discharge hole 202 through the rear horizontal part 63-1. That is, in the case of the conventional water-cooled Mig torch, the cooling water cannot be virtuously circulated when replacing the nozzle, so it is necessary to separately discharge the cooling water. This has the effect of continuously welding work.
