Abstract

The invention discloses a pipe inner surface acid pickling device and method. The pipe inner surface acid pickling device comprises a pipe feeding rack, a feeding mechanism, an acid pickling mechanism, a soaking tank and a monitoring module. The pipe feeding rack comprises a rack body, a containing mechanism and a pipe conveying mechanism. A shifting mechanism is located on the rack body. The acidpickling mechanism comprises an acid pickling chamber, a lifting mechanism and a nozzle mechanism. The nozzle mechanism is connected with an acid supply mechanism, a water supply mechanism and an airsupply mechanism. A conveying groove for placing a pipe is formed in the pipe conveying mechanism. The monitoring module comprises a monitoring box and a microcontroller. A limiting sensor and a counting sensor are arranged in the pipe conveying mechanism. The method comprises the following steps that 1, feeding a pipe; 2, conveying the pipe; 3, lifting and pressing the pipe; 4, pickling, washingand drying the pipe; and 5, soaking the pipe. Feeding, acid pickling, flushing, drying and soaking of the pipe are achieved, manual participation is reduced, and the production efficiency is high.

Description

technical field [0001] The invention belongs to the technical field of pipe inner surface pickling, and in particular relates to a pipe inner surface pickling device and method. Background technique [0002] During the cold rolling process of high-precision pipes, different degrees of processing streamlines and rolling defects (bonding, cracks) will occur on the inner surface, which will affect the inner surface quality of the pipes and the pass rate of non-destructive testing. In order to eliminate the processing streamlines and rolling defects on the inner surface, the methods of internal boring (stretching), internal honing, internal sandblasting or internal pickling are usually adopted. Internal boring and internal honing are suitable for the inner surface treatment of large-scale pipes, but it is difficult to apply to high-precision small-scale pipes. Internal blasting equipment is generally used for pipes of specific specifications, and the processing range is narrow....
