A method of using a stainless steel tube abrasive flow wiping fixture

Abstract

The invention discloses a method for using a stainless steel pipe abrasive flow wiping fixture, which comprises the following steps: (1) inserting several stainless steel pipes with the same length into the limit sleeve along the insertion hole of the limit sleeve to form a limit sleeve group; 2) Insert the lower end of the stainless steel tube of the limit set into the socket of the lower guide plate; (3) Place the bearing sleeve into the concave groove of the lower guide plate; (4) Insert the upper guide plate The socket of the plate is aligned with the upper end of the stainless steel tube of the limit set and inserted, and then the concave table slot of the upper baffle guide plate is clamped to the upper end of the bearing sleeve; (5) the clamp and the stainless steel tube are fixed into a whole Put them together between the upper and lower material cylinders of the abrasive flow machine tool, and start the machine tool to wipe the inner wall of the stainless steel tube in the fixture with abrasive flow. The invention can disperse the pressure of the abrasive flow machine tool, avoid the deformation of stainless steel pipes under pressure during the wiping process, and realize simultaneous fixed wiping of multiple stainless steel pipes, thereby improving the wiping efficiency and wiping effect.

Description

technical field [0001] The invention belongs to the technical field of mechanical engineering and pipeline cleaning, and in particular relates to a method for using an abrasive flow wiping fixture for a plurality of equal-length stainless steel tubes. Background technique [0002] As an important carrier for long-distance transportation of oil and gas, stainless steel pipes are playing an increasingly prominent role in modern industrial construction. Especially in the field of aerospace, there is a high requirement for the purity of the gas and liquid to be transported, so there is a high requirement for the cleanliness of the inner wall of the transport pipeline. At present, the cleaning and wiping of the inner wall of the stainless steel pipe is still mostly solved by using a push-pull cleaner, which has low wiping efficiency and is difficult to guarantee the wiping effect. However, there is no systematic product for the new abrasive flow wiping technology for the inner w...
