Body with internal lines

The invention relates to bodies with internal lines or passages for conducting liquid -1 opportunities.

The internal conduit bodies currently in use generally include a metal casting lines formed therein, which are in place after casting by means of appropriately shaped cast cores made of silicon-containing Material are produced, which previously burned in a sintering process in the kiln and then before casting were placed in the kiln.

After casting, the silicon-containing casting cores are removed with appropriate tools, whereupon the internal lines or recesses formed in this way are cleaned of foreign matter that may have stuck on their walls.

If the conduits or passages to be made in the casting are assembled and tortuous, then must considerable skill are expended in casting so that the required cast cores are formed and the cast cores before the Font to be arranged correctly.

In addition, when arranging the casting cores in their correct position, particular care must be taken to prevent the casting cores from shifting to avoid during the casting process, resulting in a decrease in the wall thickness of some of the inwardly running lines and cause the wall thickness of other conduits to increase relative to their intended dimensions, and possibly to Could lead to defects in the casting.

All the preparatory work for the Gu ¹ B of such known body with pipes is particularly difficult when fabricating bodies provided with pipes to be used in modern air brake systems for rail vehicles, in which the large number of internal lines or passages, as they are normally required The difficulties encountered in this work are further increased in order to address the various compressed air circuits, whereby extensive specialization is required by the skilled personnel, as well as a considerable amount of time is required for an accurate implementation of the work and, accordingly, relatively high production costs for the Casting occur.

The aim of the invention is to simplify the production of Bodies with internal lines for carrying liquids.

According to the invention, this 7iel is achieved with a body with inwardly extending lines in that the body has two comprises individual parts with interacting surfaces, with at least one depression or recess in one or both surfaces is provided, and the two parts are held together with their interacting surfaces in a liquid-tight manner, wherein the indentations or recesses that run inside Form lines or passages.

The inwardly running lines or passages can by means of Openings that extend through the components are connected to spaces outside the same.

The components can for their part be attached again outside on parts of the system of which they are to form a part, and connected to them in a liquid-tight manner.

It is obvious that from the use of the invention A considerable simplification results. Should be a composite system of internal lines are formed, it is sufficient simply a two-dimensional arrangement of golf learners to build up the necessary deepening in the. To form parts; in general, such a guiding process is easy to carry out.

It is obvious dal? this method of making the with inwardly running lines provided body not only limited to the production of cast metal parts in earth molds it can also be used in permanent mold casting, die casting and casting techniques in which sheet metal is pressed into relief molds will; in the last two cases the manufacturing costs are even lower.
