Definitions
- the problem with conventional steel drums is that the inside edge of the weld seam is often the cause of premature rust formation and contamination of the filling material. It is therefore desirable to flatten and smooth the weld seam or the overlapping material area. B. enables a continuous, closed application of a colored coating and the formation of rust nests, particularly in the interior of the container, is largely prevented along the weld seam.
- a roller is attached to the outside of a free cantilever; this must absorb large forces and be dimensioned large enough to avoid bending.
- the cantilever arm is rotatably mounted for a continuous production process; however, large masses have to be moved disadvantageously in short time intervals.
- the rolling machine is designed as a linear continuous rolling machine, in which the upper roller support part processing the inner surface of the frame is, so to speak, "floating", ie. H. is equipped with an alternating central and external locking mechanism in relation to the lower frame.
- the transport or the forward movement of the sheet metal casing in the welding machine is usually accomplished by a corrugated feed roller engaging in the area of the overlap area.
- a corrugated feed roller engaging in the area of the overlap area.
- the individual corrugations press into the material and an unsightly corrugation occurs.
- this fine corrugation also disappears.
- the overlapping wall area of the cylinder-shaped casing is rolled flat along the longitudinal seam in a longitudinally welded container, approximately twice as thick as at least 1 1/2 times or normal normal thickness of the metal plate or on the wall thickness of the frame.
- the rolling process is expediently carried out directly after the welding process at even higher temperatures of the material of the longitudinal seam region to be rolled, all unevenness being smoothed out.
- large-volume containers such as. B. a 220 liter steel barrel with a barrel wall height or weld seam length of about 900 mm
- the smoothing of the longitudinal seam represents a significant improvement in product quality.
- FIG. 1 shows an overall view of the system for longitudinal seam rolling of frames
- FIG. 2 shows a side view of the continuous rolling machine
- FIG. 3 shows a front view of the rolling machine
- Figure 4 shows a cross section through the center of the rolling machine
- Rollers and Figure 5 shows a cross section at the location of the conveyor roller drive.
- the reference numeral 10 denotes a schematically illustrated automatic welding machine, from which the frames 12 that have just been longitudinally welded run out onto a separate unloading conveyor 14.
- the frames 12 are transported further from the unloading conveyor 14 to a separate pull-off conveyor 16, from which the individual ones Frames 12 get into the actual rolling machine 18.
- the unloading conveyor 14 generally runs at the same conveying speed as the automatic welding machine 10, while the frames 12 on the pull-off conveyor 16 can be briefly stopped and accelerated again to load the rolling machine 18.
- the conveyors 14, 16 are equipped with corresponding drive motors.
- the inlet side is labeled A (loading position) and the outlet side is labeled B (unloading position).
- the rolling machine 18 has a lower rolling machine stand 28 and an upper roller support part 26.
- the upper roller support part 26 is temporarily connected to the lower roller stand 28 at its two outer ends via pivotable locking claws 32.
- the central locking pins 30 move back in the vicinity of the roller pair 20, 22 and the upper roller carrier part 26 is free over its entire length for the rolling process now taking place, the frame 12 from the loading station A via the roller roller pair 20, 22 now in operative function Unloading position B performed and the longitudinal weld seam is rolled flat.
- the lower roller roller 22, which is provided with a rotary drive 46, is raised by means of a hydraulic unit 44 and pressed against the frame weld seam and the upper roller roller 20, which supports from the inside.
- the following procedural steps take place one after the other:
- the lower rolling roller 22 is raised by the hydraulic unit 44 in the rolling position a small distance (for example 50 mm) upwards into the working position and driven by a roller motor 46;
- the frame 12 to be machined is brought up to the two rolling rollers 20, 22 and passed through the two rolling rollers 20, 22 or the roller gap remaining between them - the actual smoothing or rolling process taking place.
- FIG. 3 shows a front view of the upper roller support part 26
- Hydraulic cylinder 42 pivotable locking claws 32 can be seen, which temporarily intercept or lock the upper roller support part 26 with respect to the lower frame structure 28.
- Figure 4 shows a central cross section through the rolling machine at the location of
- Rolling roller pair 20, 22 The lower roller 22 is not yet of the
- Hydraulic unit 44 raised and therefore not yet in active engagement. The middle
- Locking pins 30 are not in active engagement here; the upper roller support part 26 is now carried or fixed only at its two outer ends via the locking claws 32 which engage from the outside (not visible here).
- Figure 5 shows essentially the roller conveyor with rollers 34, chain 36 and
- the continuous frames 12 are additionally supported and guided by support rollers 40 acting from the outside.
- the laterally engaging locking pins 30, which can be actuated by means of small hydraulic cylinders, can also be seen.
- Smoothing system for barrel frames can be rolled or smoothed up to 800 frames per hour with a cycle time of approx. 4.5 seconds.
- the frame length that can be processed is approx. 900 to 1100 mm with a frame diameter of approx.
- the overlap area along the longitudinal weld is approx. 3 mm wide.
- the frame has about twice the wall thickness before the rolling process. After the rolling process, the frame is almost flat or rolled in the overlap area to the simple, ie normal wall thickness.
