Bellows and producing device thereof

Abstract

The present invention provides a bellows and manufacturing installation thereof, wherein the bellows has such a constitution that when the transporting velocity of a flowing body thrown into inside of the tube is changed, the object thrown inside it can be cooled / heated effectively at the same time. The manufacturing installation for the bellows mentioned above comprise a control box being in combination with upper side of the body, used for controlling the start-up of a cylinder and capable of causing movement back and forth of the cylinder rod; a rimple shaping flat plate inclining at preceptive angle, mounting the rimple shaping edges in a projecting onwards mode, forming a guidance rod at one side near to the frontend of the rimple shaping edge mentioned above, and mounted at the upper side surface at one side of the body mentioned above; a movable flat plate extensible guide fixed at the upper side of the body of the rimple shaping flat plate mentioned above along the length direction; as well as a movable shaping flat plate being in combination with the upper side of a link slide block which is in combination with the flat plate extensible guide mentioned above and is capable of sliding backward and frontward, with its frontend forming a throw-in groove used for throwing cylinder type tubes supplied exteriorly to the upper side of the rimple shaping flat plate mentioned above, and being connected with the cylinder rod mentioned above.

Description

technical field [0001] The present invention relates to pipes for conveying fluids such as liquids and gases and their manufacturing devices, and more particularly to corrugated pipes having a structure in which the conveying speed of the fluids fed into the pipes is changed while cooling them efficiently. / Heats objects loaded into it. Background technique [0002] Generally, as is well known, the outer and inner peripheral surfaces of pipes used in fluid transport lines such as gas and liquid are processed to be smooth. The desired object is achieved by circulating or transporting a fluid such as gas or liquid using a tube having a shape in which the outer and inner peripheries are smoothed as described above. For example, in a cooling device of a heat-generating machine, a method of supplying cooling water to the above-mentioned pipes to cool the machine is effectively used. [0003] However, when the cooling fluid is conveyed by the smooth inner and outer pipes, it has...

Problems solved by technology

However, the above-mentioned method of using a single tube to protect the outer skin of the power line has a problem that it cannot be used when the surrounding temperature of the tube where the power line is placed is very high, because the surrounding temperature is transmitted to the tube intact.
