Rapid pipe cutting mechanism capable of moving compositely

Abstract

The invention discloses a rapid pipe cutting mechanism capable of moving compositely. The rapid pipe cutting mechanism comprises a rotary blade (1.2), a blade rotating shaft (1.4), a blade rotating drive mechanism and a pipe clamping mechanism. The rapid pipe cutting mechanism is characterized by further comprising a planetary gear train (1.3), wherein the pipe clamping mechanism is coaxial with a sun wheel (1.3.2) of the planetary gear train; a blade wheel (1.4.1) on the blade rotating shaft (3.4) is meshed with a planet gear (1.3.1) of the planetary gear train; two drums of a double-drum swing arm (1.6) are respectively sheathed on the blade rotating shaft (1.4) and a planetary gear shaft (1.5); and the planetary wheel shaft (1.5) is fixed on a rotating gear box. The rapid pipe cutting mechanism capable of moving compositely is simple in structure, low in cost and complete in functions; and with the adoption of the rapid pipe cutting mechanism capable of moving compositely, the blade can perform self rotation and revolution and can cut through automatic rotation, so that the cutting surface is complete, and the cutting is efficient and rapid.

Description

technical field [0001] The invention relates to a composite motion fast pipe cutting mechanism, in particular to a composite motion pipe cutting mechanism with blades capable of both self-rotation and revolution and radial feed at the same time, belonging to the field of mechanical engineering (work cutting). Background technique [0002] With the continuous progress of society, people's demand for high-speed and high-quality mechanical equipment continues to increase. How to meet this requirement mainly depends on structural design and functional improvement. Existing pipe cutting machines can be divided into three categories, 1 turning type - pipe rotation, turning tool cutting; or pipe fixed, turning tool revolution cutting; 2 rotary cutting type - pipe fixed, blade rotation rotary cutting; 3 The pipe rotates, and the blade rotates and cuts (such as Chinese patent 200520111997.4, a spiral coil pipe CNC multi-knife random automatic cutting machine). [0003] Looking at th...

AI Technical Summary

Problems solved by technology

[0003] Looking at the various pipe cutting instruments currently available, most of them are still traditional single-blade feeding, or use more complicated mechanisms to realize their pipe cutting functions. These machines are either low in efficiency and poor in cutting effect, or high in cost. Not suitable for individual production use

Turning type, which consumes a lot of power and the pipe is easy to deform

Rotary cutting type, the pipe is fixed, the blade rotates automatically, the blade must cut through the entire pipe, the stroke is long, and the incision is easy to tilt

The pipe rotates, the blade rotates by itself, the structure of the rotating pipe mechanism is complex, and it is difficult to process long or non-round pipes

[0004] Such a status quo does not meet the requirements of today's social development, resulting in a lot of waste of social resources, so a machine with low cost, high pipe cutting efficiency, and good cutting and forming is needed to meet this requirement
