    专利说明:

    The invention relates to a method for producing a hose connection with a pressure measuring point for a pressure sensor through a closed wall.
    With the help of an electric drive and a fan, a volume flow is generated in industrial extraction systems, which transports dust-laden air. The air is then cleaned with the help of one or more filter elements.
    In order to ensure an optimal operating state of the system, the current volume flow must be measured. The pressure measuring point with measuring nipple has proven to be practical and almost independent of the choice of drive as a measuring system. However, the position of the measuring nipple is predetermined in commercially available solutions due to the fastening holes and can only be changed afterwards with considerable additional effort, e.g. by drilling new fastening holes or by repositioning the nipple itself. In addition, a new thread may have to be cut. The position is important, as turbulence in the discharge area of the fan can influence the measurement accuracy.
    The production of defined hose connections for pressure sensors involves many time-consuming steps and several parts.
    From DE 10 2013 001 124 B3 a hose connection arrangement is known, with a blind rivet nut which has a setting head, a threaded section with an internal thread and a deformation area, and with a hose connector which is formed in one piece with the blind rivet nut.
    The object of the invention is to provide a simplified and rational procedure for the production of a hose connection with a pressure measuring point for a pressure sensor.
    [0007] This object is achieved by a method for producing a hose connection for a pressure sensor according to the features of claim 1.
    According to the invention, the following process steps are provided:Making a hole through the wall with the diameter of the rivet extension of a blind rivet with a mandrel,Pushing the blind rivet through the hole up to the stop of the rivet head on the wall and pushing a hose with an inside diameter that corresponds to the outside diameter of the rivet extension onto the rivet extension of the blind rivet on the opposite side of the wall,Pulling the mandrel of the blind rivet.
    The newly set pressure measuring point thus offers a new fastening hole and measuring nipple. At the same time, the attachment for the measuring hose is provided easily and with sufficient long-term stability in industrial applications. A particular advantage is that existing tools are used and no new designs or procurement are necessary.
    One embodiment of the method provides that after the mandrel has been pulled, a remaining terminating part of the mandrel of the blind rivet is pierced in the direction of the attached hose. This process step is advantageous with versions of blind rivets in which a tear-off part remains after being pulled.
    [0011] The invention is explained further below with reference to the drawings. The schematic representation shows in detail:<tb> Fig. 1 <SEP> a schematic representation of a hose connection produced by the method according to the invention,<tb> Fig. 2 <SEP> a view of the head of the blind rivet in the air flow area of the inlet nozzle,<tb> Fig. 3 to 8 <SEP> the individual process steps, and<tb> Fig. 9 <SEP> a schematic representation of a hose connection produced according to the method according to the invention with a pressure measuring point during operation.
    The same reference numbers in the figures designate elements that are the same or have the same effect.
    In Fig. 1 is a schematic representation of a hose connection 1 produced by the method according to the invention is shown in the wall 3 of the inlet nozzle. 2 shows schematically the top view of the rivet head 8. The arrangement forms the pressure measuring point.
    The area of the rivet extension 5 thickened by the pulling of the mandrel of the blind rivet clamps the previously attached area of the hose 9 securely and firmly.
    The rivet head 8 of the blind rivet is located in the area of the inlet nozzle through which air flows. The air duct 12 through the blind rivet head forms a connection to the hose 9. The pressure sensor can be connected to this (not shown).
    3 to 8 show the method according to the invention in individual steps.
    3 shows the wall 3 to be penetrated for the sensor / hose connection.
    In Fig. 4, the production of a hole 4 through the wall 3 with the diameter of the rivet extension 5 of a blind rivet 6 with mandrel 7 is illustrated by the arrow.
    Fig. 5 shows the insertion of the blind rivet 6 through the hole 4 up to the stop - see also Fig. 6 - of the rivet head 8 on the wall 3 and attaching a tube 9 with an inner diameter which corresponds to the outer diameter of the rivet extension 5 the rivet extension 5 of the blind rivet 6 on the opposite side of the wall 3.
    Fig. 7 shows the pulling of the mandrel 7 of the blind rivet 6 in the direction of the arrow with the end part 10 of the mandrel 7 being torn off. The pulling can be done with normal blind rivet pliers. In this case, the rivet extension 5 expands in the area of the attached hose 9. The end part 10 of the blind rivet can, if necessary, initially remain in the widened area of the rivet after the mandrel 7 has been torn off and must then be removed in this area.
    Finally, as shown in Fig. 8, the end part 10 of the mandrel 7 of the blind rivet 6 is pierced in the direction of the attached hose 9. For this purpose, e.g. the mandrel 7 that was previously torn off with the aid of the rivet pliers can also be used together with light hammer blows.
    After removal of the terminating part 10 from the hose 9, the hose connection through the wall 3 of the inlet nozzle for a pressure sensor is completed. After completion of the work, the aerodynamically excellent rivet head 8 remains in the air-flow area. The attached hose 9 holds without glue or other fastening measures.
    9 shows the hose connection 1 with the rivet head 8 during operation for measuring an air flow 11 through the air duct 12 and the hose 9.
