Automatic Fillet Welding Machine for joining Ring Frame to Unit}

The present invention relates to a ring frame fillet automatic welding device for a single pipe, and more particularly, a ring frame fillet for a single pipe outer plate by using a dedicated device capable of exclusive welding and having a heating tower structure or the like configured in a welding device having a welding head. Automatic welding can be easily done without additional work, and the use of dedicated equipment is related to the ring frame fillet automatic welding window of single pipe that can increase work efficiency by reducing work preparation and waiting time.

In general, in the case of a pressure pipe, a ring frame T-shaped reinforcement, which is a circular reinforcement, is attached to the inside of the pressure pipe to have strength against pressure acting on the inside or the outside.

The method of continuously welding such a ring frame is a method in which the device is welded while rotating along the welding line, or the device is fixed and welded while the end pipe, which is a working member, is rotated.

In general, the method of welding the end pipe while rotating is widely used. In this case, the precondition that the welding head of the fixed device is not far out of position as the end pipe rotates is required. Must be added to the device. In the case of welding materials, preheating and postheating are required to prevent weld defects after welding.

Conventionally, when performing the work of welding the ring frame on the outer plate of the short pipe, most of the work is done by using manual or simple equipment or dedicated equipment, but it is difficult to operate the equipment because the dedicated heat treatment does not work, and the productivity is low.

The heating tower structure 6 of the door bogie structure equipped with the plater 3 and the heating pad 19 for heat treatment which can heat both the inner and outer surfaces of the short pipe 1, and is responsible for controlling the entire apparatus. The control panel 5, a welding machine 4 provided for latent welding, and supplying a welding current, voltage, etc. to the welding torch, and a flux recovery system coupled to the manipulator 3 to recover the flux sprayed during welding ( 24 and the ring frame 2 can be welded to the end pipe 1. Turning roller (7) supporting the end pipe (1) and rotating the end pipe (1) so as not to deviate from the error limits of a certain rotational area, and the welding current, voltage, speed and preheating temperature, which are welding data when welding, can be recorded. It consists of a welding data recording board 27 that can be.

The welding head part 26 includes one horizontal shaft slide 20 on which a horizontal drive motor 10 is mounted to support twin tandem submerged welding on the outer plate 8 of the short pipe, and the horizontal shaft slide 20 2) The vertical shaft slide 21, which is mounted on each side of the vertical shaft driving motor 9, is attached, and the torch angle adjusting device 11 and the welding torch fixing bar 22 are coupled to the vertical shaft 21. The welding torch fixing bar 22 includes a welding torch 15 which performs welding while being slid by a flux spreading gate 23 and a welding torch slide 12 which can automatically open and close the flux spreading, and the welding torch. 15 is provided with a contact sensor 18 for tracking the welding line when welding, and the flux spreading tank 17 for storing the flux one by one on both sides of the welding head portion 26 is attached. It is composed.

Four wire reels 13 are installed on the lateral beams 25 of the manipulator 3 so that the wires are wound, and the wires pass through the wire feeding line 14 and the wire feeding motor 16. The welding torch 12 is supplied.

Hereinafter will be described the operation of the present invention.

The end pipe 1 is placed on the turning roller 7 so that the ring frame 2 can be welded to the outer plate 8 of the end pipe, and the manipulator 3 is moved to attach to the transverse beam 25. After the head part 27 is positioned at the end of the short pipe to be welded, the heating tower structure 6 is moved to perform heat treatment through the heating pad 19, and the welding is performed while rotating the short pipe 1 using a turning roller. do.

In the welding method, the flux stored in the flux spreading tank 17 is sprayed from the flux spreading gate 23, and the welding is performed with the two welding torches 15 while tracking the weld line through a pair of contact sensors 18. Proceed and recover the flux from the flux recovery system 24.

The present invention is not limited to the above-described specific preferred embodiments, and various modifications can be made by any person having ordinary skill in the art without departing from the gist of the present invention claimed in the claims. Of course, such changes will fall within the scope of the claims.

The effect of the present invention, which can be expected by the configuration and action as described above, can simultaneously perform heat treatment operations on the end pipe during welding, so that automatic welding of the ring frame fillet to the end pipe shell can be easily performed without additional work, and the conventional manual It is a very useful invention that not only improves work efficiency by greatly reducing work preparation and waiting time, but also greatly improves productivity compared to work using a work tool or a simple tool.
