The two flange faces of carbon steel flange are straight with each other, and the table of vertical lathe is inverted, so the main function of the tool is to operate the big head flange.The upper bolt hole connects the tool to the flange.When clamping tools on the work table, make sure that the plane of the flange to be machined is concentric and parallel to the vertical lathe table.

To reduce the number of tools, the tool should be able to change the direction of the tool to ensure that both ends of the elbow flanges can be machined on one tool.When used together, the die must have satisfactory rigidity, otherwise it will seriously affect the processing quality of the groove of the flange seal ring.Therefore, in a satisfactory environment, the height of the tool should be reduced as much as possible to increase rigidity and ease of operation.

The radius of the tool and carbon steel flange should not exceed the working radius of the vertical car and can be easily adjusted when clamping the tool.Mold stiffness verification, slotted structure cantilever beam in the mold rotation bending and change when the force, should verify deflection and rotation Angle.
