Description

Forming Method of Metal Carrier Core and Forming Apparatus {Forming Method of Metal Catalyst Converter and The System Thereof}

The present invention relates to a molding apparatus for a metal carrier core and a molding method thereof, and in particular, to prevent the disconnection of the strip generated in accordance with the play of the gear teeth in the corrugated molding portion, and also to the drive roller and the forming roller of the corrugated molding portion The present invention relates to a method for forming a metal carrier core and a forming apparatus capable of prolonging the lifespan of a driving roller and a forming roller, as well as preventing mass production of a defective core, by preventing occurrence of uneven wear.

In general, the exhaust gas purifying metal carrier is disposed in the vehicle internal combustion engine to purify the exhaust gas of the vehicle which is the main cause of air pollution, and converts carbon monoxide to carbon dioxide.

The core of such a metal carrier is made by winding a flat strip and a corrugation strip, and a conventional core forming apparatus is configured to wind the flat strip and the corrugation strip in the same direction and then wind them together.

However, the conventional core forming apparatus is arranged to be indirectly driven by the driving roller on the upper part of the driving roller in order to co-form the flat strip. Since a difference occurs in the rotational speed, the teeth of the forming roller and the driving roller collide with each other, causing a problem in that the strip passing between the forming roller and the driving roller is disconnected.

In order to solve this problem, a single gear meshed with one side of the driving roller and the forming roller is adopted to maintain the same rotational speed by directly applying rotational force to both sides, but in this case, it occurs between the intermeshed single gears. There was a problem that the strip is disconnected due to the play.

In addition, in the case of forming a large number of corrugated strips having the same width, since the support portions of the driving roller and the forming roller are fixed, when the strip is supplied to only one side of the roller, uneven wear occurs on one side of the roller. There was a problem of shortening the service life.

In addition, in the conventional molding apparatus, the flat strip and the coagulation strip are driven in the same direction and drawn into the winding part while being simultaneously gripped by one insert chuck. Due to the uneven portion of the co-rogging strip, the flat / co-rogation strip is not opened while the ends are kept in parallel with each other, so that the core is not properly gripped and mass-produced.

Therefore, in order to solve the above problems, the present invention prevents the disconnection of the strip generated in accordance with the play of the gear teeth in the corrugated forming portion in advance, and also prevents the occurrence of uneven wear in the driving roller and the forming roller of the corrugated forming portion. The present invention provides a method for forming a metal carrier core and a forming apparatus capable of prolonging the life of a roll as well as preventing mass production of a defective core.

The corrugation strip supply unit 200 includes a second spool 210 in which the flat strip 20 for the corrugation strip is wound on the other end of the main body 30, and the second spool 210 is formed. ), Like the first spool 110, a second brake 211 for controlling the second spool 210 is disposed.

At this time, the strip 20 wound on the second spool 210 is guided to the eighth and ninth guide rollers 220a and 220b, and the driving roller 238a of the corrugation forming part 300 to be described below. It is conveyed in the advancing direction by the shaping roller 238b and simultaneously molded into the corrugation, where a predetermined pressure unbalance between the second spool 210 and the driving roller 238a and the shaping roller 238b occurs. The strip 20 is moved to the left or right with respect to the traveling direction of the strip 20, and as a result, the corrugated strip 21 passing through the driving roller 238a and the forming roller 238b is bent in a zigzag direction as a whole. The phenomenon occurs.

In this case, the second brake 211 maintains a predetermined tension on the strip 20 between the second spool 210, the driving roller 238a, and the forming roller 238b to solve the above problems. It serves to hold tight.

Meanwhile, ninth and tenth guide rollers 220a and 220b for guiding the flat strip 20 supplied from the second spool 210 to the corrugation forming part 230 are provided below the second spool 210. It is arranged in the vertical direction.

In this case, like the first position sensor 130, the third position sensor 240 has its own weight on the other side with the center on one side and at the same time in the upward or downward direction depending on the tension of the co-rogation strip 21. The turning is to sense the position and to control the driving speed of the drive motor 260 according to the position value.

That is, when the corrugation strip 10 is continuously supplied to the winding unit 300 by being guided to the eleventh guide roller 220d disposed on the third position sensor 240, the winding of the core 500 is performed. As the diameter gradually increases, the winding speed is increased to move toward the other side of the third position sensor 240.

Subsequently, as the driving motor 260 is shifted to a corresponding rotation speed value by the position value measured by the third position sensor 240, the rotation speeds of the driving roller 238a and the forming roller 238b are increased. It is possible to increase the feed rate of the corrugation strip (21).

In this case, the controller 40 receives the position value detected through the third position sensor 240 and then varies the driving motor 260 at a driving speed corresponding to the position value.
