Manual spiral tube bending machine and application method thereof

Abstract

The invention relates to a manual spiral tube bending machine and an application method thereof. The spiral tube bending machine comprises a support, a driving mechanism, a rotating shaft and a bending handle, wherein the top of the support is provided with a rotating shaft seat; the left end of the rotating shaft penetrates through the rotating shaft seat and is connected with the driving mechanism; the right side of the rotating shaft seat is provided with a stop block; a rotating shaft sleeve which can rotate around the rotating shaft and axially slide along the rotating shaft is sheathed on the rotating shaft; the rotating shaft sleeve is connected with an angle adjusting block; the angle adjusting block is connected with the bending handle; the end part of the bending handle is provided with a groove, and a slide block is embedded in the groove; an idler wheel is embedded in the cavity of the slide block; and the edge of the idler wheel is carved with a semi-circle groove. The bending machine provided by the invention can be used for bending metal pipelines with various small calibres and is convenient to assemble and carry. When the spiral tube is subjected to bending, the semi-circle groove at the edge of the idler wheel and the spiral groove of a spiral shaft form an outer round of a tube, the outer round is used for locking the tube and reducing the deformation of thetube, and the problem that the tube is flatten when being bent into a spiral shape can be solved.

Description

technical field [0001] The invention relates to a pipe bending manufacturing technology, in particular to a manual spiral pipe bender and a use method thereof. Background technique [0002] In engineering application or equipment manufacturing process, in order to absorb the deformation of long pipes when the temperature changes or to use pipes for heat exchange to increase the heat exchange area, it is necessary to adopt the helical structure of the pipes, but the factory-made pipes do not have a direct helical structure. The machine-powered spiral pipe production equipment can meet the production of large quantities of spiral pipes. At the same time, in order to avoid the flattening of the pipe during the production of the spiral pipe, the common method is to fill the inside of the pipe with sand or other fillers to complete the bending work. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a manual spiral pipe ...
