A non-magnetic stabilizer forging process

Abstract

The invention relates to a non-magnetic stabilizer forging process. The steps of the process are as follows: (Step S01): blooming forging on an oil press: the 5000-ton oil press is utilized to do preliminary blooming work, a big step is drawn out to be hot Phi710, and small steps at both ends are drawn out to be hot Phi540; (Step S02): strengthening forging on a precision forging machine: the 1400-ton precision forging machine is adopted for forging forming, pull or push forging is performed after a clamp A and a clamp B are adopted for clamping, so that the small steps are forged into a preform size, the small steps at both ends are forged into a target size after temperature decreases to be lower than 800 DEG C, and finish forging temperature is not lower than 600 DEG C; (Step S03): strengthening forging on the oil press: the unstrengthened parts of the surface of the forging are forged at high speed to be strengthened under low pressure, deformation is 5 percent to 10 percent, and finish forging temperature is not lower than 500 DEG C; (Step S04): physical and chemical testing. The non-magnetic stabilizer forging process provided by the invention can produce non-magnetic stabilizers with uniform mechanical properties in each part and good magnetic property by utilizing the oil press and the precision forging machine for joint forging.

Description

technical field [0001] The invention belongs to the technical field of forging, and relates to a non-magnetic stabilizer forging process. Background technique [0002] With the development of my country's petroleum industry and the continuous improvement of drilling technology, the demand for non-magnetic stabilizers of various specifications is increasing year by year. Since the shape of the non-magnetic stabilizer is similar to that of a shuttle, the difference between the large step in the middle and the small steps at both ends The step difference is large, and it is relatively difficult to ensure that the performance indicators of each part are basically consistent. It is not easy to deform and strengthen the operation. In addition, this steel type has a large deformation resistance at low temperature, and a little carelessness may cause the product to be scrapped. Therefore, very high requirements are put forward for the manufacture of products, and basically all the non...

Problems solved by technology

Due to the large step difference between the adjacent large and small tables without magnetic stabilizers, and the limited size range of the forgings clamped by the forging manipulator, the margin of the small table is often relatively large. In order to prevent eccentricity, it is even possible to increase the transitional steps. In addition, In the forging process, due to the characteristics of the non-magnetic steel itself, the amount of deformation will not be too large each time, and multiple fires are required to complete the forging. This production method has relatively high production costs.
