This utility model discloses a composite heat exchange tube and its production equipment, including: a substrate pretreatment device, an inner and outer tube insertion device, a filler layer coating device, and a composite tube drawing device. The inner and outer tube insertion device inserts the inner tube into the outer tube. The filler layer coating device is located in the middle of the inner and outer tube insertion device. During the insertion process, the filler layer coating device coats the outer surface of the inner tube. The outlet of the inner and outer tube insertion device is equipped with a composite tube drawing device for drawing the inserted heat exchange tube. The composite heat exchange tube proposed in this utility model solves the problems of high cost, short lifespan, and easy corrosion of existing stainless steel heat exchange tubes through innovative structural design and process optimization.

The present invention relates to a machine (1) for forming sheet metal by drawing, which comprises two lines of jaws (7) arranged opposite each other and carried by mechanical means allowing their movement in space.This forming machine (1) is characterized in that said lines of jaws (7) have an adjustable length, each one comprising:a first group of jaws (71a), designed to allow the forming of a sheet metal by longitudinal drawing, anda second group of jaws (72a) comprising at least two jaws (72) suitable for occupying:(a) an inactive position, at a distance from the first group of jaws (71a), to allow the latter to perform said longitudinal draw forming, and(b) an active position, in alignment with the first group of jaws (71a), to enable, together, the forming of a sheet by a transverse drawing.

The present invention relates to a sheet metal stretching forming machine (1), which comprises two lines of jaws (7) arranged opposite each other and supported by mechanical means allowing their movement in space. This forming machine (1) is characterized in that said lines of jaws (7) have an adjustable length, each comprising: - a first group of jaws (71a), designed to allow the forming of a sheet metal by longitudinal stretching, and - a second group of jaws (72a) comprising at least two jaws (72) capable of occupying: (a) an inactive position, at a distance from the first group of jaws (71a), to allow the latter to perform said longitudinal stretching, and (b) an active position, in line with the first group of jaws (71a), to allow, together, the forming of a sheet metal by transverse stretching.
