Embodiment Construction

[0019] Move the movable flange end face processing machine to the equipment that needs to be processed, first fix the flange pieces on the equipment on the four flange surface pinning systems, and fix the flange pieces in the "匚"-shaped frame 44, Align the bolt hole of the flange with the groove 47 or hole 48 on the "匚" font frame 44, and fix it with bolts and nuts. "匚" font frame 44 is fastened on the vertical support 3 with bolt 45 again. Then adjust the center control adjustment system to keep the vertical support 3 perpendicular to the horizontal support a 2, and the center of the flange piece coincides with the center of the flange processing machine. Tighten the centering bolt 42 and fastening bolt 43. Adjust the central positioning bolt according to the size of the flange piece to be processed, and the adjustable range is 0~70mm.

[0020] After the flange sheet and the processing machine are fixed, turn on the motors A and B, and under the action of the motor transmis...

Abstract

The invention discloses a movable flange end face machining machine which comprises a frame, a motor transmission system, a central control adjusting system and a flange face pinning system. A flange sheet of a device to be machined is fixed to the machine through the flange face pinning system and the central control adjusting system, turning tool feeding is conducted through transmission of a motor, the turning tool conducts large circling motion around the center of the flange end face machining machine and conducts high-speed small circling motion around one transmission shaft parallel to a central shaft of the flange end face machining machine, and therefore the purpose that the flange face is turned is achieved. The machine can be directly transferred to the device to be machined, the flange sheet is directly machined, the flange sheet does not need to be cut, the machining time is shortened, and the machining cost is reduced.

Description

technical field [0001] The invention relates to a flange surface processing machine, in particular to an adjustable and movable flange end surface processing machine. Background technique [0002] Flanges are parts that connect pipes to pipes, or pipes to equipment outlets, and are widely used in pressure vessels, tanks and pipelines. During use, linear cavitation is easily formed on the end face of the flange, causing damage to the sealing line of the flange, resulting in seal failure, equipment leakage, and affecting production and operation. [0003] For the repair of the damaged flange end face, the traditional method is to cut the corroded and damaged sealing surface at the weld and send it to a fixed lathe for processing; another method is to add sealant to the corroded surface. In the former method, the flange is cut off, the pressure vessel, the tank body or the pipeline are damaged as a whole, and the repair of the flange takes a long time. In the latter method, t...
