Elbow and Elbow Manufacturing Method
The invention discloses an elbow and an elbow manufacturing method. The method comprises the steps that two end faces and one point of a pipe having through holes are pressurized to form a first bending part so that the pipe can be bended, forming a first spare piece; with the pressure for forming t...

| description | The invention discloses an elbow and an elbow manufacturing method. The method comprises the steps that two end faces and one point of a pipe having through holes are pressurized to form a first bending part so that the pipe can be bended, forming a first spare piece; with the pressure for forming the first spare piece as the standard, two end faces of the first spare piece is pressurized more heavily, and the one point is pressurized more lightly, so that the first bending part forms a second bending part, and a second spare piece, more bended than the first spare piece is formed; with the pressure for forming the second spare piece as the standard, the two end faces of the second spare piece is pressurized more heavily, and the one point is pressurized more lightly, so that the second bending part forms a third bending part (the upper and lower length is smaller than the two-side length, and the two sides protrude outwardly, and a third spare piece, more bended than the second sparepiece, is formed; the two |
