Abstract

The invention relates to a steel pipe end vibration upsetting joint device and method. The method includes the following steps that (1) a steel pipe end is heated through a coil heating device; (2) the steel pipe end is put at a station of a machine tool, and a non-heated portion is fixed on a base of one end of a machine tool platform; (3) colloidal graphite or a high-temperature lubricating agent is applied in a mold cavity of a vibration device; (4) a push plate device at the other end of the operation platform is started, the platform is linearly pushed by means of a pushing force of a push rod to approach the workpiece end, and the mold cavity of the vibration device is matched with the steel pipe end; (5) an auxiliary vibration exciter and a vibration exciter of the vibration device are started so that the vibration device can perform X and Z direction vibration and upsetting is achieved after multi-time extrusion vibration. The steel pipe end vibration upsetting joint device and method has the advantages that the vibration device is applied to upset-extruding of the steel pipe end in stead of traditional large hydraulic devices, the purpose of hot working of the steel material end can be easily achieved, and the thermal deformation effect of the steel pipe end is excellent by means of vibration and impact of hot forging force.

Description

technical field [0001] The invention relates to a steel pipe end forming device and method, in particular to a steel pipe end vibration upsetting joint device and method. Background technique [0002] The original steel pipe end pier roughing machine and end forming machine are bulky, low in efficiency, high in cost, and the quality of the products produced by them is unstable. Especially in oil field production, oil pipe fittings such as oil pipes, casings, and drill pipes are mostly connected by flexible joints at the ends, and such a split connection structure will lead to breakage during downhole operations. Seriously affect safe production and efficiency. The Chinese patent document publication number is 101041173, and the patent name is "A Method and Device for Upsetting and Forging the End of Coupling Oil Casing and Casing". After heating two oil casings at the same time, they are transferred to the station roll of the upsetting and forging forming equipment. On the...
