A method of manufacturing a duct system for heating the fluid within the modular bimetallic heating radiators


(57) Abstract:

The method is intended for use in the manufacture of bimetallic heating radiators. Modular element body is collected in the form of punching, then get a working body, in which an end part of the workpiece are in the aisles, no thread. Then on the production line with an intermediate flow above the working body are installed one after the other in cutting installation on a support, where the couple oleodinamica enters the cylinder at the same time, the cutting device passes which cut off the end pieces and push them through the holes. Work the body, thus formed, has in the aisles holes structural steel pipes. Then on the production line corps arrive at another installation, where in the aisles tapped. In this way, Assembly of the system occurs without the use of welding, which significantly reduces labor costs and provides security. 3 C.p. f-crystals, 13 ill.

The invention relates to a steel pipeline systems bimetallic heating radiators. Such systems can be performed without the use of welding and ustborovoe, with passages connecting tubes buildings modular elements. The above horizontal pipes are working part remaining from the workpiece inserted into the aluminum casing in the process of manufacturing the heat sink using stamping under high pressure, gradually tapering at the ends with sections that allow heat to reach these passages buildings modular elements.


If you compare with a heating radiators, with only one item and is manufactured by pressing, bimetallic modular radiators, characterized by a system of pipelines, integrated inside aluminum construction, have the advantage that the size and shape of the heat sink can be selected to suit the individual requirements of the users at a lower cost of manufacturing, inspection and Assembly, because of its simple Assembly, lower weight and minimum dimensions. And also, because the modular components are designed to be formed with the aluminum housing, which can be manufactured using a stamping under high pressure, their appearance can be easily varied in Savisaar of the pair of horizontal line segments of pipelines, which can be connected in a variety of ways; therefore, they can be made either by press-fitting or welding segments of pipelines, or coaxial installation of the serial segments of the pipelines. The disadvantage of the first system are the high operating costs associated with the use of welding and with the risk of explosions; as for the second system, although it does not use welding, however, the Assembly process is quite complex, because the valves of the pipes shall be secured to sections of the pipelines, which are located outside the main structure of the underlying item. Disadvantages of the second system is due to the fact that heating radiator modular parts must be installed with the use of intermediate devices, such as adapters fixed stabilizers, or equipped with a set of mounting elements on the suspension. When compared to known manufacturing techniques and technologies described in this invention, it can be noted that the invented system execution pipeline has the following advantages: a) the most significant part of the design can be performed during installation of the radiator through Wenchuan is odule radiator which has openings for line segments connecting pipes, placed in such a way that they correspond to the position of the pipe segments due to the original build system described in this invention; b) provide a cheaper, lighter heating element having a smaller size, because it can be fabricated using a minimum number of strands of steel pipes by forming under pressure, which can be completely performed on the automated line; C) Assembly and installation of the piping can be performed even by non-specialists, since it is simple and logical; g) safety, because the manufacturer does not use the welding pieces of steel pipes are joined along the line of the thread, which ensures a tight connection pipes; d) since there are no external connections for this type of piping system need only the elements aluminum casing that allows a good fit of the product in the interior space.

Information confirming the possibility of carrying out the invention

Part of the produced heat sink includes a modular element with aluminum structural body 1, which has at the ends of a pair of passages 2 thread 3, in which there is a center hole 4 d in aluminum structure, is the bearing element of the piping system. Modular element with aluminum housing 1 can be manufactured from billet steel structure 6, which is placed in the form of punching to obtain business buildings, where the end part 7 of the workpieces 6 out in the aisles 2, with smooth walls. Then on the production line 8 with the intermediate flow above the working body are installed sequentially one after the other in cutting installation 9 on a support 10, a pair of oleodinamica cylinder 11 at the same time provides input cutters 12 in aisles 2, which is cut end portion 7 and push them through the holes 13. Thus is formed a working body having passages 2 holes structural steel pipes. On the production line 8 working body, thus obtained, are served to the next working installation, in which the thread 3 in 2 passes. The Assembly process is completed by screwing segments steel horizontal pipe having an external thread corresponding to the female thread in the passages 2.

Billet steel structure 6 made of two pieces of pipe 20 has a parallel intermediate sections, welded at the points 21, which prevents the penetration into the molten aluminum when carrying out the forming of the housing 1. The heating device must be installed by placing two or more modules with aluminum structural body 1, with the lock in a certain position, with the o ring 24, the pre-placed between the two flanges 22 and 23. As was said above, the Assembly ends by screwing one or more of the segments 14 of the pipe, forming a horizontal line, in the passages 2 to the matching of the holes 15 with holes 4 steel pipes 5. Installation is completed by screwing the part 16 of the pipe at the beginning of the pipeline and part 17 of the pipe at the end of the pipeline, and the holes 18 of the portion 17 of the pipe must be aligned with the holes 4 of the last modular element.
