Embodiment Construction
[0031] Referring to the accompanying drawings, an apparatus for mesh formation according to the present invention is generally designated by reference numeral 1 .
[0032] The device is operatively interposed between a feed unit 2 for feeding a continuous lead strip (of a known type not shown in the drawings) and a pulling unit 3, said The feed unit 2 is arranged upstream of the traction unit 3 . Advantageously, a mesh leveling unit 4 and a lug cutting unit 5 can be arranged at the exit of the traction unit 3 along the same cliche production line. In this way, lead plate products can be produced with a single and very compact production facility 6 as shown in FIG. 1 .
[0033] Reference will now be made to an embodiment of an apparatus 1 for forming a continuous lead strip for battery panel production, it being understood that the material constituting the strip may be any alloy suitable for battery production.
[0034] With particular reference to Figures 2, 3 and 4, the ap...

Machine for making grids for accumulator plates, comprising a supporting structure (7) lying on the ground and mounting die means (9) operatively acting upon a continuous lead tape that translate with a substantially constant speed along an advancement direction (A), movement means (10) for moving the die means (9) with an advancement speed component that is oriented along the advancement direction (A), and with an expansion speed component that is oriented along a direction (B) that is normal to the translation direction (A). In turn, the movement means (10) comprise a first motorised eccentric shaft (11) mechanically coupled with the die means (9) through a movement transmission unit (12). According to the invention, the movement means (10) further comprise at least one second eccentric shaft (13) rotationally driven in phase with the firs (11) eccentric shaft that is mechanically coupled with the movement transmission unit (12) for imparting a speed correcting component to the die means (9), said speed correcting component being oriented along the advancement direction (A) in opposite sense with respect thereto.
Description
technical field [0001] The invention relates to a device for forming a grid for battery panels. [0002] The device according to the invention can be effectively used in the production process of accumulators, wherein a continuous grid is obtained starting from a continuous lead strip, which is cut into pieces of predetermined length in order to obtain pieces to be inserted into accumulators single plate. Background technique [0003] Now, according to the prior art, equipment for forming lead strips is usually operated in a batch mode. [0004] To this end, such equipment is traditionally provided with a feed system capable of advancing the lead strip in steps through a die, whereby the strip is expanded and thus formed into the plates mesh. [0005] It is known that in such devices the strip is stopped corresponding to the expansion zone in order to be shaped and expanded by means of the teeth of the die, usually driven by movement means also connected to the feed syste...
