Description
The present invention relates to a device for manufacturing a curved tube type heat insulating cover, and more particularly to a device for forming a curved tube type heat insulating cover having a bulging portion at an upper end of a curved tube type heat insulating cover and having durability and flexibility .
The present invention relates to a curved tube type thermal insulation cover for piping insulation, and more particularly to a curved insulation cover for protecting a thermal insulation covering an elbow pipe in insulation construction of pipes such as a water pipe, a gas pipe and a double complementary pipe. do.
In order to protect the insulation material for piping, a curved insulation cover is generally constructed by assembling a bent plate material according to a predetermined angle, so that the construction is accomplished by a worker having a high skill level There is a problem that construction by a general worker is impossible.
In order to solve the problem of the above working efficiency, KR 20-0207806 and KR 20-0273517 disclose a binding means or a clip binding portion on both sides of a split duct which is horizontally or vertically divided.
In addition, Korean Patent Publication No. 10-2013-0000195 discloses a protective case with a heat insulating material, which facilitates insulation of piping by integrating a heat insulating material and a protective case.
In order to enhance the durability of the curved surface portion, the curved tube-type heat insulation cover is used as a tubular tube by bending a tube-shaped tube. The tube-shaped tube, which is expanded as it bends the tube, There is a slight plastic deformation due to excessive bending, and there is a problem that it is easily broken even with small external force during transportation, transportation or installation.
As a method for solving the above problem, in Korean Patent No. KR-10-1156662, instead of the conventional method, a tube-like double insulated tube having a bellows tube made of synthetic resin or metal and a plurality of spacers flexibly bent However, the conventional problem of using the corrugated tube has not been solved.
In order to provide convenience of the construction, the curved tubular thermal insulation cover is preferably formed as a one-piece structure that is divided into two without being divided into a plurality of pieces. Second, it is preferable to form a corrugated tube considering flexibility and thermal expansion of the second construction, In order to enhance the durability of the insulating cover, it is preferable to provide a radiation type bulging portion.
SUMMARY OF THE INVENTION It is an object of the present invention to provide a device for forming a curved tubular thermal insulation cover having a bulging portion only at an upper end and having durability and flexibility at the same time.
It is still another object of the present invention to provide a manufacturing method for manufacturing the above-mentioned curved tube type heat insulating cover.
In order to accomplish the above object, the present invention provides a method of manufacturing a heat exchanger, comprising: a lower mold (22) and an upper mold (23) for molding a curved upper heat insulating cover (11); A

The present invention has the following effects.
First, it is manufactured as a single unit which is not divided into a plurality of units but divided into two, and can be simply constructed as a binding unit.
Second, since the upper insulating cover is provided with the bulging
Third, since the bulging portion of the upper heat insulating cover disposed radially with respect to the center of the bending portion has the effect of increasing the strength of the heat insulating cover.
Fourth, since the bulging

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.
In order to provide ease of construction, the curved tube type heat insulation cover is provided with a curved tube type thermal insulation cover which is firstly formed into an integral type divided into two without being divided into a plurality of pieces, The present invention provides a manufacturing apparatus for forming a thermal insulation cover having only a radiating-type bulging portion (12) with respect to a central core of a tube only in an upper thermal insulation cover in order to cope with expansion and contraction.

In the present invention, since the heat insulating cover having a bulging portion is integrally formed, it can be stably used for a long period of time under expansion and contraction due to temperature change. Moreover, since there is no welded portion, cracks are not generated and moisture and the like are not penetrated. There is no damage, it is possible to maximize the effect of insulation and insulation, and the production period and production cost can be greatly reduced.
