    摘要: A device for removing external circular fins from pipe joints comprising a base, a hollow rotor with a faceplate mounted in the base, carriages located on the rotor faceplate, a mechanism for radial traverse of the carriages, having a holder rotatably fitted on the rotor, and a drive for the rotor and the mechanism for traversing the carriages. Each of the carriages is provided with a roller adapted to trace over the surface of the pipes being treated, while the mechanism for radial traverse of the carriages is composed of links with one of their ends articulated to the holder and with the other end to slide blocks, each of which is housed in a bore in the respective carriage with the possibility of radial movement therein and is connected to a spring gauged for the cutting force, the other end of which spring thrusts against the bottom of the carriage bore. The drive of the rotor and of the carriage traversing mechanism has two output shafts, of which one is kinematically associated with the rotor, while the other shaft is kinematically associated with the holder, which drive is provided with a mechanism for program control of the difference between the rotational speeds of the shafts.

    摘要: A welding apparatus employing a self-contained pumping accumulator plant hydraulically associated with a hydraulic ram of a moving clamp transfer gear for gripping pipes being welded. The apparatus employs a device for decreasing the pressure in the hydraulic ram and in a pilot valve during flashing and for increasing pressure during upsetting. The apparatus also employs a a low-pressure high-capacity pump with a filter, a relief valve, a nonreturn valve and an unloading slide valve, two high-pressure low-capacity pumps and a device for cutting the pumps and the unloading slide valve in and out. The pumping accumulator plant and the high-pressure pumps communicate with a main oil plant; a hydraulic control of the slide valves of the clamp hydraulic drives is connected to the pumping accumulator plant. The pilot valve is controlled by a welding process program control actuator.

    摘要: According to the present invention the radial feed mechanism comprises a hydraulic cylinder on the rod of which is rigidly fixed a holder connected with the housing of the radial feed mechanism by springs which ensure the cutting force of the cutting tool. At one end the springs bear against the housing of the radial feed mechanism while at the other end they bear against the holder rotated by a drive mounted on the tool head body and the shaft of said drive is rigidly connected with the housing of the radial feed mechanism. The housing of the radial feed mechanism carries a slide valve whose rod interacts with the profiled surface of a master form rigidly fixed on the tool head body. The holder is provided with rollers for tracing the internal surface of the welded pipe. The advantage of the device according to the present invention resides in that it ensures removal of flesh regardless of its temperature. Besides, the device allows the flash to be removed uniformly around the perimeter of the joint even in case the welded pipes are out-of-round. Further, the device allows to maintain practically constant cutting force during the flash-removing process.
