The invention discloses a conversion tool for realizing production of diodes of different power on a same production line. The conversion tool comprises an aluminum strip and combing strips, wherein the combing strips comprise a first combing strip and a second combing strip; the teeth pitch of the first combing strip is the same as that of the aluminum strip; and the teeth pitch of the first combing strip is double of that of the first combing strip. The invention also provides a production process based on the conversion tool for realizing production of diodes of different power on the same production line. According to the conversion tool, the diode leads with the rated power of xA and the diode leads with the rated power of 2xA adopt the same production line (wherein x is 3, 4, or 5), and share the same unified winding displacement machine, welding tray, acid cleaning tray, aluminium strip and other tools; therefore, the operations of combining strips, gumming, curing and baking can be carried out in an unified manner; and in the die-pressing and forming operation, the materials can be separated through the conversion tool, so that the investment of machinery equipment is lowered, the production efficiency is improved, the consumption of acid, white gules and other chemicals is reduced, the production cost is lowered, and environmental pollution is reduced.
