The manufacturing process of drum mixer through the Union and product obtained by recravamento

摘要

The manufacturing process of drum mixer through the Union for recravamento and product obtained.It is described a process for manufacturing concrete mixer drum through the Union for recravamento and product comprising a process performed in three steps through the manufacture of the upper part (100), the manufacture of the lower part (200) and completion of the union of the structures (30 Through the recravamento (32) with air tightness,Resulting in a prismatic circular structure (300) with angled (301), describing in its upper portion opening (302) and rebound of the Union (303) from the process of recravamento.The fabrication process allows the elimination of soldana manufacture of drum mixers and promotes the reduction of manufacturing time, and reduce the need for labour by increasing the efficiency in the manufacturing process and preventing the deposition of material of high cost of S. Oldagem.
