Definitions
- the invention relates to a method for welding sheet metal frames according to the preamble of patent claim 1 and a resistance roller seam welding machine according to the preamble of claim 7. Resistance roller seam welding machines, short
- Roll seam welding machines can weld up to 1000 cans per minute. This means a high
- Transport speed of the welded metal frames of about 100 m / min. the necessary temperature can be achieved in order to be able to optimally weld the two slightly overlapping edge regions together. But this also means that through the
- Welding roller pair and subsequently made with a second pair of welding rollers are detected and, based on the detected values, the welding pressure, i. the
- Sweat arm is located, ever a correspondingly high
- Welding pressure can be applied.
- a division of the welding of the edge areas to two Welding machines are not technically feasible, except in a case in which a sheet metal frame after the other one in a single welding station and is pushed out again.
- An object of the present invention is to increase the quality of the weld of Blechzargen despite high welding speed. This object is achieved by a method according to the features of patent claim 1 and a resistance roller seam welding machine according to the features of
- Heating zone in front of the welding rollers are the
- Edge areas guided by suitable guide elements such as Z- or S-rails mutually exactly positioned and can therefore following the heating zone exactly overlapping and contacting between the
- Welding rollers are routed. Furthermore, the guide elements allow the welding arm to be in front of it
- Welding rollers where the current through the overlap area has to FeH, which leads to an increase in resistance. It can therefore with a single welding transformer, a different heat generation between the Heat zone and the welding zone are applied, so that the edge areas are therefore only heated and not welded before entering the welding rollers and then by increasing the temperature due to higher resistance between the welding rollers
- Figure 1 is a schematic representation of a
- Figure 2 is a schematic representation of a
- Heating zone in front of the welding rollers heating zone formed by two current-carrying
- FIG. 3 shows a section along line A-A in Fig. 1,
- FIG. 4 shows a section along line DD in FIG. 1
- Figure 5 is a section along line BB in Fig. 1 and
- FIG. 6 shows a section along line C-C in FIG. 1.
- Figure 1 which represents the prior art, comprises a welding device 1, a power source 3 with a first power supply 5 to the schematically illustrated welding arm 23 within the designated with reference numeral 7 sheet metal frames.
- a second power supply 9 feeds the outer first welding roller 11 of the first welding station and further the second welding roller 13 of the second welding station.
- the two welding rollers 11 and 13 are above the arranged inside the sheet metal frames 7 first inner welding roller 15 and the second inner welding roller 17.
- Reference numeral 19 diabolo rollers of a guide cage are referred to, which are arranged in a circle around the sheet metal frames 7 and lead them.
- the sheet-metal frames 7 guided from left to right are welded for the first time, and with the second welding roller 13 and the second inner welding roller 17 a second welding or welding of the first welded seam takes place.
- the welded at the first pair of welding rollers 11, 15 edges of the sheet metal blank 7 already produce a completely closed can body. This can be on the
- a welding arm 23 is attached via a guide rail 25 and is supported by the guide rail 25.
- the welding arm 23 may for example have a round or rectangular cross-section and extends from a Einrundstation not shown to the
- the just rounded sheet metal frame 7 is visible on the far left.
- the sheet-metal frame 7 or its edge regions 7 ⁇ and 7 "are spaced apart from one another and in this first region between the section line AA and the section line BB they are replaced by a welding arm 23 connected and above with the machine frame 21 also connected first guide rail 25 in a spaced position out (see Fig. 2 and Fig. 6). By the first guide rail 25, therefore, the welding arm 23 is supported.
- the sheet metal frames 7 are guided from left to right until the two edge portions 7 ⁇ and 7 "get to a pair of heating rollers 27,29 and in the region of the section DD are clamped by the heating rollers 27, 29.
- the edge regions 7 ⁇ and 7 are heated to a temperature ⁇ by the current conducted through the two heating rollers 27, 29.
- the temperature ⁇ may be 200 ° C or more.
- the temperature ⁇ is far below the
- the welding arm 23 is suspended on the machine frame, since the second guide rail is connected to both the welding arm and with the machine frame 21 (Fig. 4).
- the additional suspension of the welding arm 23 at the heating zone, the outer welding roller 13 can with the necessary welding pressure to the inner welding roller 17 and on the overlapping to be welded edge regions 7 ⁇ and pressed 7 ", as has long been in
- the optimum welding temperature 2 is perfectly achieved by a perfect edge guide, overlap and contact force of the resistance of the current.
