Abstract

The invention discloses a small-diameter pipe cutting and beveling machine, which belongs to the technical field of pipe installation engineering; the invention uses a power handle 33 to connect with a pinion shaft 21 through a connecting block 3301, and transmits power to the moving ring of the main cutting motion mechanism. ;The clamping mechanism is installed on the static ring I15 and the static ring II14 in the main cutting motion mechanism to realize the clamping of the workpiece; the radial feed mechanism is fixed on the moving ring in the main cutting motion mechanism, and realized The tool makes a radial feed motion. The invention transmits motion and force to the main body of the mechanism through a pair of bevel gears, changes the direction of energy transmission and operation, and is convenient for operators to operate; the throttle valve, filter, gate valve, air motor, bevel gear and other mechanisms are integrated into the Among the power handles, it has good integration and portability; by replacing the clamping blocks with different lengths, it can clamp pipes with different diameters and achieve the purpose of cutting and beveling.

Description

technical field [0001] The invention relates to the technical field of pipeline installation engineering, in particular to a small-diameter pipeline cutting and beveling machine. Background technique [0002] Pipeline repair and welding work is frequently encountered on engineering projects, many of which are buried underground or completely exposed. Pipelines that have been underground for a long time will be retested by acid and other substances, and pipelines that have been exposed for a long time will be damaged or even broken due to natural and human factors, so regular inspections and corrections are required. [0003] The pipe cutting and beveling machine refers to the pipe cutting or beveling operation when the pipe needs to be repaired and installed. It solves the shortcomings of flame cutting, grinder grinding and other operating processes such as irregular angles, rough slopes, and high working noise. It has the advantages of easy operation, standard angle and sm...
