Abstract (en)
A pipe bending machine having an improved movement transmission to a bending die comprises a body (1) and a head (2). Housed in the body (1) is a motor (3) having an output shaft (4) supporting a driving gear wheel (5), which is located in the machine head (2). Located in the same machine head (2) is a driven gear wheel (8), which is connected to a pipe bending die (6). A couple of intermediate gear wheels (9, 10) engage both the driving gear wheel (5) and the driven gear wheel (8).
