High-flux tube surface longitudinal groove machining device

Abstract

The invention discloses a high-flux tube surface longitudinal groove machining device. The machining device comprises a support, a workpiece clamp and a rolling structure, wherein a partition plate isarranged inside the support, a screw rod is arranged on the partition plate in the support, and a guide rod is arranged on the partition plate below the screw rod; an oil tank is fixed on the left side of the upper end of a workbench, an oil cylinder seat is fixed on the workbench on the right side of the oil tank, a driving gear is arranged on an output shaft of the oil cylinder seat, and a rotating motor is fixed on the side face of the output shaft on the side face of the oil cylinder seat; and a supporting frame is arranged on a sliding seat, and the workpiece clamp is arranged on the workbench on the right side of the supporting frame in a sliding mode. According to the high-flux tube surface longitudinal groove machining device, the tooth shape and the groove shape of longitudinal groove pipes are determined through the tooth-shaped convex block structure in the middle part of a rolling mould, and through the semi-arc size of the rolling mould, the positioning of steel tubes aredetermined and the steel tubes cannot be deformed; and the longitudinal grooves are formed conveniently, the claw hand is pushed by an air cylinder to move forwards and backwards, the air cylinder ismatched with a limiting block to drive the claw hand to clamp the workpiece, so that the high-flux pipes with different pipe diameters are automatically adjusted.

Description

technical field [0001] The invention relates to the technical field of pipe processing, in particular to a high-flux pipe surface longitudinal groove processing device. Background technique [0002] High-flux tube is a heat exchange tube with high efficiency and enhanced heat transfer. High-flux tube is the most used heat exchange equipment in power, petroleum, chemical and other industries. It has good heat exchange effect and can withstand high temperature and high pressure It is easy to maintain in the equipment, and the structure is also very firm, so the high-flux heat exchange tube plays an important role in the production application. In recent years, the scale increase of petrochemical plants and the production of large-scale equipment have become an important part of chemical production. An important trend, the application of high-flux heat exchange tubes is also more and more needed. The structure of high-flux heat exchange tubes is to sinter a layer of porous powd...
