Description

Rotary Type Looper for Metal Pipe Forming {A Rotary Type Looper}

In the present invention, when manufacturing a metal pipe, a roll type steel strip (Roll Type Metal Strip) which is installed in the middle of an uncoiler and a pipe mill and supplied from an uncoiler is preliminarily stored. While supplying the discharge to the pipe mill (Pipe Mill) in order to connect the end of the iron plate to be supplied and the end of the iron plate to be supplied to each other in order to continuously supply without stopping the supply of the iron plate This was done by improving the Rotary Type Looper for metal pipe forming to pre-save.

To describe this in more detail, the roller is fixed to the inside of the outer rotating drum mounted at equal intervals on the outer periphery, while the guide rollers on the outer periphery of the central fixed drum are mounted at the same intervals in the screw line, Install the inner middle fixed drum part and the outer rotating drum part on the outside of the drum part, but vertical guide rollers are installed on the outer side of the outer rotating drum part and the inner middle fixed drum part at equal intervals to support the iron plate band wound around the outer circumference. It is possible to drive the vehicle in a right state, and it is equipped with an iron plate belt feeding device inside the outer rotating drum so that it can be supplied while pulling the iron plate wound around the uncoiler. When the reverse fixing device is installed on the cavern fixing drum and the outside rotating drum is rotated to turn the iron strip to the outer circumference It is possible to prevent the iron plate band already supplied to the central fixed drum from slipping or being pulled out by the rotational force of the outer rotating drum and to be discharged to the outside. The fixed drum allows the drum angle to be adjusted by the variable device so that the looper can be installed vertically without inclination and can be easily supplied to the pipe manifold while maintaining the iron plate in parallel. To provide a rotary type looper for forming metal pipes that allows the guide drums to be installed to be collectively adjusted by the roller angle deviation adjusting device so that they can be discharged while maintaining the iron strips that are rolled out without being distorted or distorted. will be.

While continuously supplying the iron strips to the metal pipe shape by the tube, the metal pipes are generally formed by supplying the iron strips rolled up in rolls, and the steel strips on the rolls are generally 10 depending on the molding conditions. It takes about 20 minutes.

However, in the past, when forming a metal pipe by a tube tube while supplying the iron strip on the roll as described above, after the exhaustion of one iron strip completely, the operation of the tube was to be stopped in order to load the other strip. If the tube is stopped and operated again after each time of loading, the metal tube is molded again, causing a lot of defects at the end of the supplied iron plate and the newly supplied end, and when loading the steel plate again. There was a problem that the molding efficiency is significantly reduced because the tube is stopped and the molding time is consumed according to the replacement time.

In order to solve this problem, it is possible to continuously supply the iron plate strip to the tube tube while welding the end of the iron plate strip which is supplied after the ship by the welding device, but when welding the end of the iron plate strip placed after the ship by the welding device. A vertical type looper was proposed by Kent Corporation in the United States that allows welding of both ends of a steel strip positioned before and after without stopping operation.

It draws out the iron plate attached to the uncoil by the side pinch roller and guides it by the side guide while supplying it to the outside guide group through the guide plate so as to be in close contact with the inside of the outside guide group, and to the outside guide group. After changing the direction of the steel plate to be changed in the U-shaped conversion part, the inner guide group is rotated one turn, and the iron plate band wound to the inner guide group is rotated along the guide roller installed in a spiral manner, and then the It is to be supplied.

In order to weld the end of the supplied iron plate and the end of the iron plate to be newly supplied in order to continuously supply new iron plate as the iron plate strips are almost exhausted, the conventional vertical looper (Vertical type looper) ) Will work as follows:

Increasing the rotational speed of the side pinch rollers increases the feed rate (supply length) of the iron strips than the discharged (discharge lengths) discharged through the measuring rollers. While moving in the advancing direction of the iron plate, the inner guide roller group and the outer guide roller group are rotated and stored. At this time, the iron plate band maintains the spring force so that it is not only in close contact with the outer guide group but more than one time. If it is stored in a circular winding, it will not flow anymore.In this way, when the iron plate strip is restored to the outer circumference of the inner guide roller group and the outer guide roller group, the plate pin roller is restored to its original state. The inner circumference of the inner guide roller group and the outer guide roller group is maintained in the state of being stored.

As such, when the end of the iron plate is supplied while the iron plate is continuously discharged while storing the circumference of the inner guide roller group and the outer guide roller group, the end of the existing iron plate and the tip of the iron plate to be newly supplied. Is welded integrally by a conventional welding device, and the iron strip is stored on the outer circumference of the inner guide roller group and the outer guide roller group while the rear end and the tip of the iron plate strip positioned before and after are welded. Since it is supplied in order to the tube, it can be operated continuously without stopping the tube. After completing the welding of the rear end and the front end of the iron plate strip which are placed before and after, the side pinch roller is operated at the original speed to continuously operate the iron plate strip. You can supply it.

In the conventional vertical type looper configured and operated as described above, the following problems are pointed out as disadvantages.

Conventional upright looper (Vertical type looper) only pushes the iron plate strip by the side pinch roller when supplying the iron plate strip for metal pipe forming, so the iron plate is wound around the inner guide roller group and the outer guide roller group. There was a problem that the band was deformed or distorted, and since the inner guide roller group and the outer guide roller group were not equipped with a device for supporting or guiding the iron plate, the iron plate was not stored uniformly and neatly. There was a phenomenon that the bending or twisting, and the U-shaped bent portion that is converted from the outer guide roller group to the inner guide roller group is also not naturally formed and there is a problem that can not be supplied smoothly to the iron plate strip.

In particular, the guide roller installed in the center of the iron plate strip supplying and storing device mounted on the base is fixed type and the guide roller is fixed so that the input side of the discharged iron plate and the tube is aligned in the same line. In order to install the roofer inclined to be inclined, thereby maintaining the unstable installation state, there was a problem that must be installed while changing the inclination of the expectations according to the characteristics of the metal pipe to be manufactured.

In addition, due to the characteristics of the structure, the outer guide roller group and the inner guide roller group should always be stored by winding more than one layer of iron plate bands, which has to be checked and supplemented from time to time so that the steel plate bands are stored in two or more layers. In this case, if the amount of the steel sheet stored in the uncoiler is reduced during supplementary storage, the steel sheet cannot be stored in the looper in sufficient quantity. Therefore, the steel sheet is supplied longer than the time required for welding the ends of the steel sheet to each other. There was a problem that can not be done to stop the operation of the tube.

In order to solve this problem to some extent to improve the domestic patent registration No. 313474 "rotary looper" is known.

It is equipped with a fixed drum on which the spiral winding roller group is formed on the outer periphery, but the inner winding roller group is installed on the outside of the fixed drum in a circular shape, and the outer guide roller group is installed on the outside of the inner winding roller group in a circular shape, and the entry side is provided. In the case where the pinch roller, the guide roller and the measuring roller are installed on the discharge side, the guide roller and the outer winding roller are mounted at equal intervals between the outer side of the inner winding roller group and the outer guide roller group. By installing a rotating drum equipped with a turning guide drum therein, the conventional base is to be inclined at an angle of 72 to 78 degrees.

It is operated by the pinch roller to push the iron plate strip, and the pushed iron plate band is guided to the rotating drum by the induction roller, and the direction is changed from the direction change guide drum to the fixed drum side, and is input to the fixed drum. It is to be discharged through the guide roller and the measuring roller after moving the spiral winding along the spiral winding roller group mounted on the outer circumference. When the steel plate is to be stored in the looper, the rotating drum is rotated by a predetermined device. The iron plate is to be wound around the outer winding roller mounted on the outer circumference of the drum.

However, the conventional rotary looper constructed and operated as described above has the following disadvantages.

Since the iron plate strip is pushed and fed by the pinch roller when feeding the iron plate strip, there is a problem that the iron plate strip is pushed or distorted, and the device induces the direction change of the iron plate strip even when the direction is changed by turning the direction change guide drum. Since the iron plate strips pushed out of the direction of the direction change guide drum because it is not installed, there was a problem that can not be supplied smoothly to the spiral winding roller group of the fixed drum.

In addition, when the rotating drum is rotated to store the iron plate, there is no device for guiding and supporting the iron plate that is wound on the outer periphery of the rotating drum. Due to its elastic force, it was shot outwardly and the coiling state was released, causing the peeling to the outside of the rotating drum. Even if the stripping phenomenon does not occur, the iron plate wound on the rotating drum does not maintain a correct posture and is twisted or distorted. The phenomenon occurred.

Therefore, due to the phenomenon of twisting, distorting or stripping, the iron plate band input between the spiral winding roller group of the fixed drum and the inner winding roller installed on the outer side is also in an unstable, distorted or warped state. While maintaining the iron plate in the correct state not only can not be supplied to the tube, the pipe formed by the tube was also a problem such as the appearance of warpage, there was a problem that the quality is reduced.

In addition, when the rotating drum is rotated in order to store the iron plate on the rotating drum, the iron plate is rotated while the part is wound around the circumference of the direction changing guide drum. The phenomenon that the iron plate band that has already been introduced to the fixed drum side is pulled back by the direction change guide drum, which causes a delay in the supply to the tube tube, so that the tube tube cannot smoothly form the metal pipe.

In addition, the iron plate strip, which is passed through the looper and supplied to the tube, is a guide drum for changing the direction, and the upper and lower sides of the changed iron plate strip are supported only by the measuring roller. This causes the impact generated when passing through the looper to be maintained, and therefore, the tube duct cannot easily form the iron plate in which the impact is maintained at the beginning of molding.

In addition, in order to maintain the iron plate band input to the tube, the hassle has to be installed inclined by the angle of 72 ~ 78 degrees of the roofer is installed, and the device is maintained in an unstable state because the anticipation is inclined The angle of the expectation should be precisely adjusted according to the condition of the metal pipe and the steel strip to be molded, but there was a problem that the expectation and the looper were made of metal and thus could not be easily adjusted.

The present invention is to provide a rotary type looper for metal pipe molding further improved to solve the above problems.
