Description

Longines Peter-up Machine for Continuous Operation {Sequence Longi Fit-up Machine}

The present invention relates to a longage peter-up device for automatically welding the longage to the abacus of the hull structure, and more particularly, when the long-up welded to the abacus stops the peter-up carriage at each welding position after the abacus magnetizing operation Continuous and shortened the welding time by eliminating the hassle of intermittent and repeated automatic welding after the press and long press operation and continuously performing abacus magnetting, long press pressing, and automatic welding during the Peter-up carriage. It relates to a working longage peter-up device.

In general, a device for mounting a longage peter-up header on a conventional gantry-type girder to weld a longage while the long-edge peter-up carriage is traveling has a peter-up carriage at a welding position according to a preset longage welding interval. Once positioned, the Peter-up carriage was brought to a complete stop, followed by abacus magnetizing, long press pressing, and automatic welding. The 32-point pointer requires two points of welding with both torches in a single welding operation, so the same operation must be carried out 16 times. To weld a single lunge, the longage peter-up carriage must run and stop 16 times. The lower abacus magnetting unit and the upper long press pressing unit must repeat the full stroke up-down movement at each stop. Due to the waste of liver, the long welding time is excessive and there is a problem that causes a decrease in productivity.

SUMMARY OF THE INVENTION The present invention has been made to solve the above problems, and its object is to improve the longage welding speed by continuously performing abacus magnetting, long press operation, and automatic welding operation while the longe peter-up carriage is traveling. It is to provide a longage Peter-up device for continuous operation that can improve the productivity by reducing the number of long welding welding by reducing the indirect working time.

In order to achieve the above object, the peter-up header runs according to the welding interval previously set, and the long-term peter-up carriage is stopped every time the welding position is reached, and the pusher cylinder mounted on the long-pressing unit is lowered. Unlike the method of pressing the long press to return the cylinder after the welding operation and returning to the home position, in the present invention, the roller is mounted at the end of the long press pressing unit so that the roller rotates when the long peter-up carriage travels along the long flange flange surface. The unit was configured to run at the same speed as the Peter-up carriage and to operate by pressing the upper pusher cylinder when the welding position was reached. The unit was configured to run at the same speed as the Peter-up carriage even at the time of long press.

In addition, the magnetizing unit pulling the abacus to eliminate the gap with the abacus is conventionally lowered the magnet composed of the electromagnet by the air cylinder when the Peter-up carriage is stopped, and the magnet is turned on when the abacus and the magnet contact. 0N) magnetization of the main plate, the magnet is raised in the state in which the main plate is magnetized, pulls the main plate, and when the welding operation is completed, the magnetic force of the magnet is turned off (0FF) and returned to its original position, unlike the present invention. The two magnets that transmit magnetic force to the abacus are composed of electromagnets and are always on (0N), and the air cylinder is mounted on the magnet to hold the magnets a few millimeters apart from the abacus. When the welding position is reached while driving with the up-carriage, the air cylinder is lowered to contact the magnet and the main plate. When the abacus is magnetized at the same time as the contact, and the magnet is in contact with the abacus, the repulsion unit does not perform a separate upward movement, and the repulsion pressing unit transmits the repulsive force of the force that presses the ronji to the magnetizing unit to pull up the abacus. The work is carried out, during which the magnet remains stationary at the initial magnetizing position and the Peter-up carriage continues to run as the welding is completed, so when the welding is completed, the magnet follows the Peter-up carriage Since the upper air cylinder is operated to raise the magnet from the abacus to the original position, the system is configured to return to the home position by self-drive along the EL guide while moving to the next welding position.

On the other hand, the welding carriage unit travels in the same direction and speed as the Peter-up carriage when driving, while the roller presses the longage by the pusher cylinder during the welding operation and at the left and right distances at the end of the torch head by the tag-pitch. The installed torch is lowered to the welding position, and arc generation occurs after a few seconds. At this time, the torch is configured to drive in the opposite direction of the Peter-up carriage driving direction than the speed of the Peter-up carriage by its own driving. As a result, the torch is the same as the speed considering the torch speed in the Peter-up carriage. The longage Peter-up device for continuous operation is carried out to carry out the welding work as the guide moves forward and to return to the home position in the same direction as the driving direction of the Peter-up carriage along the El Am guide while moving to the next welding position after the welding work is completed. It can be provided.

First, the guide roller 50 for maintaining the straight line straightness is set in a state where the long paper is arranged at right angles with the main plate, and the roller 30 mounted at the end of the long paper pressing unit 3 is pushed to fit the long paper height 33. It is lowered by) and is set on the longside flange. At this time, the position of the first roller 30 is located rearward by a predetermined distance from the center of the magnet 21 mounted on the end of the main plate magnetizing unit (2).

When the setting of the guide roller 50 for holding the long straight line and the roller for pressing the long press 30 is completed, the entire Peter-up header is driven by the Peter-up carriage 1, and the welding position is set according to the already set welding interval. When the air cylinder 20 supporting the magnet 21 is lowered, the magnet 21 and the main plate are magnetized at the same time as the contact and are fixed in place.

On the other hand, since the upper Peter-up carriage 1 continues to travel, the magnet 21 is located behind the Peter-up carriage 1 along the EL guide 23, and a certain distance behind the center of the first magnet 21. Since the mounted press roller 30 is integrally formed with the Peter-up carriage 1 and travels in the same direction to reach the center of the magnet 21, the lower pusher cylinder 33 is lowered at this time to form the Pressurizing is performed.

On the other hand, when the gap between the rouge and the abacus is eliminated by the rosin pressing force, a repulsion force is generated. The repulsive force is transmitted to the rouge magnetting unit 2 to raise the magnet 21 and use it as a force to pull the abacus.

After the long press pressurization and magnet plate magnetization are completed, the torch clamp 42 installed at the end of the welding carriage unit 4 is lowered by the cylinder 43 so that the torch guide roller 41 comes into contact with the main plate. Arc generation takes place.

At the same time as the arc is generated, the welding torch 40 travels along the EL guide 44 at a speed of V 'in the direction opposite to the Peter-up carriage 1 travel direction, wherein the upper Peter-up carriage 1 Since the vehicle is traveling at a speed of V (V> V '), the welding torch is welded in the Peter-up carriage 1 traveling direction at a relative speed of V-V'.

After completion of the welding operation, the welding torch 40 rises and travels in the same direction as the Peter-up carriage 1 at the speed of V " The speed of the welding torch 40 returns to the origin at a relative speed of V + V ".

For the same reason as described above, it is invented to perform abacus magnetting, long press pressing, and automatic welding operation without stopping the longage peter-up carriage 1 for each welding position when performing a welding operation.

The present invention is a longage peter-up device for constructing a longage peter-up header in a gantry-type girder and performing welding while driving by the longage peter-up carriage. Abacus magnetting, long press pressing, and automatic welding can be performed while the carriage is running, reducing indirect work time and actual welding work time, resulting in improved productivity by shortening long welding time.

For the above reasons, when the long paper is welded to the main plate of the hull structure, the long paper peter-up device for continuous operation is installed by automatically attaching the long paper peter-up header to the gantry type girder and tracking the long paper. It is a very useful invention that can reduce equipment idle time, improve equipment operation rate, and reduce cycle time required for long welding operation, which can reduce labor welding and improve productivity.
