A machine for deforming the wires of grids for making electric accumulators, which comprises two lower molds, and two upper molds which are positioned above the lower molds and which are operable to shift between a raised position, in which they are separated from the underlying lower molds, and a lowered position in which they are pressed against the lower molds to deform the wires of the grids on a grid strip. The upper molds comprise respective projecting molding areas and respective seats which are positioned between the molding areas of the relative upper mold, and each housing a corresponding piece-detacher element which, when the upper molds are in the raised position, is suitable to interfere with the grid remaining attached to the corresponding upper mold to separate the grid from such upper mold.

1. A machine for deforming the wires of grids to make electric accumulators, comprising: a support structure (2) provided with at least one sliding channel (3) extending in a direction of extension (X) along which a grid strip of grids in succession is susceptible to advance;at least a first lower mould (4) and at least a second lower mould (5), which are attached to said support structure (2) in said sliding channel (3) aligned with each other in said direction of extension (X), and are suitable to receive in succession the grids of said grid strip;at least a first upper mould (6) and at least a second upper mould (7), which are fitted on said support structure (2) respectively above said first lower mould (4) and said second lower mould (5);drive means (8) connected to said first and second upper mould (6, 7), and suitable to shift said first and second upper mould (6, 7) between at least one raised position in which said first and second upper mould (6, 7) are respectively distanced from said first and the second lower mould (4, 5) to permit the passage of said grid strip, and at least one lowered position, in which said first and second upper mould (6, 7) are respectively pressed against said first lower mould and second lower mould (4, 5) to deform the wires of the grids of said grid strip;said first lower mould (4) and said second lower mould (5) being respectively provided with first and second shaped grooves (11, 12) delimited by corresponding first and second concave surfaces, and suitable to receive the wires of corresponding parts of the grids of said grid stripsaid first upper mould (6) comprising: first projecting moulding areas (13), which are provided with third shaped grooves (14) delimited by third concave surfaces and positioned aligned above corresponding first shaped grooves (11) of said first lower mould (4), and the first projecting moulding areas (13) of which, with said first upper mould (6) in said lowered position, are suitable to abut on said first lower mould (4) compressing a first part of the wires of said grids between the first and third concave surfaces respectively of said first (11) and of said third (14) shaped grooves;first seats (15), which are positioned between said first projecting moulding areas (13) and each house a first piece-detacher element (16) which, with said first upper mould (6) in said raised position, is suitable to interfere with a second part of the wires of said grids remaining attached to said first upper mould (6), to separate said grids from said first upper mould (6);said second upper mould (7) comprising: second moulding areas (17), which are provided with fourth shaped grooves (18) delimited by fourth concave surfaces and positioned aligned above corresponding second shaped grooves (12) of said second lower mould (5), and the second moulding areas (17) of which, with said second upper mould (7) in said lowered position, are suitable to abut on said second lower mould (5) compressing said second part of the wires of said grids between the second and the fourth concave surfaces respectively of said second (12) and of said fourth (18) shaped grooves;second seats (19), which are positioned between said second moulding areas (17) and each house at least a second piece-detacher element (20) which, with said second upper mould (7) in said raised position, is suitable to interfere with at least said first part of the wires of said grids remaining attached to said second upper mould (7), to separate said grids from said second upper mould (7). 2. The machine as claimed in claim 1, characterised in that each said first and second piece-detacher element (16, 20) is provided with an abutment surface (16′, 20′) facing downwards and destined to receive in abutment corresponding parts of the wires of said grids remaining attached respectively to said first and to said second upper mould (6, 7); said first and second upper mould (6, 7) in said lowered position, respectively having said first and second moulding areas (13, 17), positioned at a lower height than the abutment surfaces (16′, 20′) respectively of said first and said second piece-detacher element (16, 20);said first and second upper mould (6, 7) in said raised position, respectively having said first and second moulding areas (13, 17), positioned at a greater height than the abutment surfaces (16′, 20′) respectively of said first and said second piece-detacher element (16, 20), to bring said grids into abutment on said abutment surface (16′, 20′). 3. The machine as claimed in claim 1, characterised in that each said first and second piece-detacher element (16, 20) is integrally attached to said support structure (2) respectively distanced from said first and from said second lower mould (4, 5). 4. The machine as claimed in claim 1, characterised in that: said first and second moulding areas (13, 17) and said first and second seats (15, 19) extend parallel to said direction of extension (X). 5. The machine as claimed in claim 4, characterised in that each second moulding area (17) of said second upper mould (7) is aligned with a corresponding said first piece-detacher element (16) of said first upper mould (6), and each second piece-detacher element (20) of said second upper mould (7) is aligned with a corresponding said first moulding area (13) of said first upper mould (6). 6. The machine as claimed in claim 1, characterised in that the third concave surfaces of the third shaped grooves (14) of said first upper mould (6) and the fourth concave surfaces of the fourth shaped grooves (18) of said second upper mould (7) are respectively wider than the first concave surfaces of the first shaped grooves (11) of said first lower mould (4) and than the second concave surfaces of the second shaped grooves (12) of said second lower mould (5). 7. The machine as claimed in claim 1, characterised in that said first lower mould (4) comprises several first projecting moulding zones (23), which are provided with said first shaped grooves (11), and several first blank areas (24) arranged alternately with said first projecting moulding zones (23); said first projecting moulding zones (23) are positioned facing against corresponding said first moulding areas (13) of said first upper mould (6) and being susceptible to receive in abutment said first moulding areas (13) with said first upper mould (6) in said lowered position; the second lower mould (5) comprising second moulding zones (25), which are provided with said second shaped grooves (12), and several second blank areas (26) arranged alternately with said second moulding zones (25); said second moulding zones (25) being positioned facing against corresponding said second moulding areas (17) of said second upper mould (7) and being susceptible to receive in abutment said second moulding areas (17) with said second upper mould (7) in said lowered position.
