[0002] The centralizer is also called the guider, which refers to the rigid and flexible centralizing frame installed on the outer surface of the casing in order to ensure that the casing string being run in is located in the center of the wellbore in oil and gas drilling; the traditional integral strong elastic casing centralization The processing device of the centralizer needs to be manually loaded during operation, and the labor intensity is high. The stability of the centralizer body cannot be guaranteed during processing, and the quality of the centralizer produced cannot be guaranteed. When the traditional integral strong elastic casing centralizer processing device is used Heating and extrusion are carried out separately, the steps are cumbersome and the work efficiency is low

The invention relates to the technical field of petroleum equipment, in particular to a processing device for an integral strong elastic casing centralizer, which cuts a steel pipe into sections and processes several rectangular grooves to obtain a centralizer body, and the centralizer is fed through a feeding cylinder The green body is pushed into the fixed pipe seat, and the three pressing blocks are driven by the fixed pipe motor to clamp the centralizer green body, and the centralizer green body is driven to rotate directly under the pipe expansion mechanism by the rotating cylinder, and the lifting cylinder drives the pipe expansion mechanism to enter Inside the centralizer blank, the centralizer blank is extruded and shaped by the shaping block, and after cooling, an integral strong elastic casing centralizer is obtained; the invention can automatically load the centralizer blank, and the centralizer blank The body is fixed to ensure the stable processing of the centralizer body, thereby ensuring the quality of the centralizer. The invention uses a tube expanding mechanism to extrude from the inside of the centralizer body to heat and shape the centralizer body. Pressing simultaneously, fast and efficient.
