Multi-head overlong spiral tube molding machine

Abstract

The invention relates to a tube processing and molding device, in particular to a multi-head overlong spiral molding machine, comprising a main machine and a material-receiving bracket, wherein the main machine is installed with a feeding device, a winding device and a supporting device; the winding device comprises a hydraulic cylinder which is arranged in the middle part of an engine base of the main machine; the hydraulic cylinder is connected with an oscillating shaft which is arranged between two main frames; the oscillating shaft is connected with an intermediate shaft which is arrangedbetween two main frames through an oscillating arm; the two ends of the oscillating shaft are installed with oscillating rollers; the two ends of the intermediate shaft are installed with upper rollers; a third shaft is arranged at the lower part of the intermediate shaft between the two main frames; the two ends of the third shaft are installed with lower rollers; and the swing arm is installed with a spiral roller. The invention has the beneficial effects of simple and convenient operation, low cost, good molding quality of the spiral tube and high processing efficiency.

Description

technical field [0001] The invention relates to a pipe processing and forming equipment, in particular to a multi-head ultra-long spiral pipe forming machine, which belongs to the technical field of mechanical processing. Background technique [0002] At present, spiral pipes of various specifications are widely used in industrially produced cooling devices or heat exchange devices. Existing spiral tubes are produced by winding or rolling methods, but the winding method has certain limitations. Because spiral tubes with different diameters and pitches require different processing molds, the number of molds required is large, increasing The production cost is increased, and the size of the spiral tube is fixed and cannot be changed flexibly. It is not easy to control the amount of springback during winding, which also makes it difficult to grasp the size of the spiral tube. Although the above-mentioned shortcomings can be overcome by using the roll bending method to process ...

Problems solved by technology

Existing spiral tubes are produced by winding or rolling methods, but the winding method has certain limitations. Because spiral tubes with different diameters and pitches require different processing molds, the number of molds required is large, increasing The production cost is increased, and the size of the spiral tube is fixed and cannot be changed flexibly. It is not easy to control the amount of springback during winding, which also makes it difficult to grasp the size of the spiral tube.

Although the above-mentioned shortcomings can be overcome by using the rolling method to process spiral pipes, the operation is complicated. The existing equipment is limited to the production of single-head spiral pipes, and there is no equipment for producing multi-head spiral pipes.
