Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
139 words
Machine for effecting the soldering of water boxes onto collectors of heat exchangers, comprising a revolving table, mountings removably fitted on said table at the periphery thereof, said mountings having all identical sockets provided with supports suited for various types of water boxes and collectors of heat exchangers to be worked upon, at least the portions of said collectors to be soldered upon extend substantially always in the same horizontal plane, infrared radiation rows located beneath a fixed armature above said table on one part only of the periphery of said table, and thrust members provided to bear on the top of the water boxes of the exchangers positioned in the mountings. 2. Machine according to claim 1, wherein said the mountings are substantially of trapeze shape and placed side by side on the periphery of the revolving table.
Claim 2
Dependent Claim
22 words
Machine according to claim 1, characterized in that the thrust members are formed by axially movable rods and provided with a ballast.
Claim 3
Dependent Claim
81 words
Machine according to claim 3, characterized in that the rods forming the thrust members traverse the revolving table in guides and are placed over a ramp for operating, controlling their rise and descent, so that said thrust members are obliterated in a zone provided for the cooling of the soldered heat exchangers, and positioned for work at the end of a zone provided for positioning the heat exchangers to be soldered, in order to be actuated below the infrared heating rows.
Claim 4
Dependent Claim
37 words
Machine according to claim 1, characterized in that the peripheric edge of the table is provided with support members for receptacles intended to contain parts for positioning in the mountings in the charging zone of the machine.
