Definitions
- the invention relates to a method for producing a cooled ring carrier according to the preamble of claim 1.
- the invention is based on the problem of improving the known method for producing a ring carrier with a cooling channel to the extent that it can be carried out in a simple manner and that it avoids the disadvantages of the prior art.
- a finished pressed salt core is inserted into the recess, which is fastened in the holder by means of an adhesive connection.
- Fig. 1 shows a section through a ring carrier with a recess for receiving a salt core
- Fig. 2 is an enlarged view of an area of the ring carrier marked A in Fig. 1.
- a ring carrier 1 shown in section in FIG. 1 for a piston ring 2 arranged on its outside has a recess 4 on its ring carrier back 3 in the form of a recess open at the bottom.
- the ring carrier 1 is produced in a known manner from an alloy consisting of gray cast iron with an 18% nickel content.
- the ring carrier 1 is placed in a casting mold, which is filled with aluminum, for example.
- salt granulate is introduced into the recess 4 with a pressure of 100 to 300 N / mm 2 pressed in so that a salt core 5 is formed from the salt granulate.
- a loss of volume of the salt granulate can result in projecting webs on the wall of the cooling channel 6, which can be turned off if necessary.
- a pressed salt core 5 can also be inserted into the recess 4.
- the salt core can then be held in the recess 4 by means of an adhesive connection.
- a second process step of the consisting of the ring carrier 1 and the salt core 5 composite is pre-heated to a temperature of 200 ° C to 250 ° C before the ring carrier salt core composite 2 1/2 to 5 V for 2 minutes in a third method step is immersed in an alfin bath which consists of an aluminum melt at a temperature of about 730 ° C.
- an alfin bath which consists of an aluminum melt at a temperature of about 730 ° C.
- FIG. 2 shows an enlarged view of an area marked with A in Fig. 1, in which the ring carrier 1 with the piston ring 2, the recess 4 mounted on its back 3 and the salt core 5 pressed therein are clearly recognizable.
