Steel pipe outer surface descaling device

Abstract

The invention discloses a device for descaling the outer surface of a steel pipe. The device comprises a showering mechanism, a descaling main machine, a washing mechanism and an airing mechanism arranged in sequence; the descaling main machine is characterized in that A spiral elevator is arranged on the top of a machine frame and is connected with a carriage; the carriage slides on the machine frame by virtue of a guide rail pair; the carriage is fixedly connected with the inner ring of a swing bearing; a gear motor is connected with the outer ring of the swing bearing; four sets of brush plate components are uniformly distributed on the outer ring of the swing bearing at intervals along the circumference direction; each set of brush plate component is characterized in that a screw rod is arranged on a T-shaped groove bottom plate, the screw rod is sleeved on a T-shaped slide block, the T-shaped slide block is fixedly connected with a support frame, a swinging plate is sleeved on a shaft of the support frame by virtue of a swing block and freely rotates, a spring is hinged between the support frame and the swinging plate, two abrasive brushes are arranged on the bottom of the swinging plate, and a guide block is arranged between the two abrasive brushes. The device for descaling the outer surface of the steel pipe is efficient, environment-friendly and energy-saving and does not cause secondary pollution; water and the abrasive brushes are used for descaling the outer surface of the steel pipe, the efficiency for descaling the steel pipe is improved, the cost is lowered, the occupation space is small, and pollution to the environment is avoided.

Description

technical field [0001] The invention relates to a descaling device, in particular to a descaling device for the outer surface of a steel pipe. Background technique [0002] Currently existing steel pipe descaling methods: [0003] 1. Descaling with manual tools mainly uses wire brushes and other tools to polish the steel surface, which can remove loose or lifted scale, rust, welding slag, etc. However, the descaling efficiency of manual tools is low and cannot realize product automation, and it is relatively harmful to human body. [0004] 2. Pickling and descaling Chemical pickling can remove scale, rust, and old coatings. Although chemical cleaning can achieve a certain degree of cleanliness and roughness on the surface, pickling is prone to over-corrosion and hydrogen embrittlement, and acid mist is harmful to the human body and the environment. [0005] 3. Shot peening and descaling Shot peening is a method of removing metal rust by using compressed air or mechanical ...

AI Technical Summary

Problems solved by technology

However, the treatment of the steel plate by shot peening is easy to deform the workpiece, causing great environmental pollution, and can only be operated in a closed space.
