Definitions

  • the invention relates to a plastic hollow part having an end-side connection contour for attaching an attachment part and a support element arranged on the connection contour.
  • a plastic hollow part is provided in particular for the conduction of fluids, for example, intake air in a motor vehicle or air conditioning air, but also liquids can be passed through the plastic hollow body.
  • hose clamps are often used to ensure a process-tight seal between the two components.
  • the plastic hollow parts, on which the elastomer hoses are placed have a connection contour for the passage of fluids onto which the hose ends are attached. Since plastics under permanent forces in effect may have the tendency to relax, a support ring made of metal is used on the inside of the plastic component. Against this support ring, the hose clamp is supported and clamps both the elastomer hose and the connection contour.
  • the receiving contour for the arranged on the inner circumference of the connection contour support ring is mechanically reworked.
  • This mechanical post-processing is done by a cutting process, for example by a stepped bore or a spindle.
  • chips of various types are produced. Since the chips can not be dissipated reliably, there is a risk that some of the chips remain in the component. In some applications, residual chips can be harmless, but with the use of components in the clean air area chips are not acceptable because they are directly fed, for example, the internal combustion engine and can cause damage there.
  • the object of the present invention is therefore to provide a plastic hollow part which avoids the risk of damage to downstream components. According to the invention, this object is achieved by a plastic hollow part with the features of claim 1. Advantageous embodiments and further developments of the invention are listed in the subclaims.
  • the plastic hollow part according to the invention with an end-side connection contour for attaching an attachment part and a support element arranged on the connection contour provides that the support element is arranged on the outer circumference of the connection contour.
  • the support member is positioned on the outside of the connection contour, so that no cutting process steps are necessary, which could lead to contamination of the fluid path, in particular airway. Even if a machining of the outer periphery of the connection contour should be necessary, the chips would not accumulate inside the hollow plastic part, so that there is no danger of the following components. As a rule, however, no reworking of the blow-molded plastic hollow part will be necessary since the outer contour of the connection contour is formed by the tool.
  • the support element for example a support ring
  • the support element is mounted with some pressure on the connection contour.
  • a development of the invention provides that the support element is formed in the connection contour, that is already inserted in the blow mold during the molding of the plastic hollow part or the connection contour. As a result, a particularly firm connection between the support element and the connection contour is realized.
  • the formation of the support element as a support ring causes effective support against the radially acting forces by a hose clamp or other safety devices.
  • Alternative geometries can be and are provided depends on the connection contour.
  • polygonal support elements preferably with a closed cross-section.
  • a metallic support element is preferred as support element in order to ensure sufficient strength with low weight and easy machinability.
  • a securing contour for the support element may be formed; this securing contour is, for example, a shoulder which has a larger diameter than the support surface of the support element on the connection contour.
  • This securing contour can already be produced during the molding process of the plastic hollow part or the connecting contour, whereby at the same time an increase in the withdrawal forces of the securing element is provided.
  • the fuse contour in a subsequent operation, for. B. by thermal embossing, with a very large radial projection or molded.
  • a further development of the invention provides that at the end remote from the end face of the mounted support element, a sealing shoulder is formed, the tightness between the Kunststoffblasteil and the attachment, for example, the elastomer hose, produces after mounting the hose clamp or other security device.
  • the sealing shoulder can simultaneously form an abutment shoulder for the support element, so that together with the securing contour the Support element is optionally set in the axial direction with the formation of a low clearance.
  • the sealing shoulder can be made very narrow or have an angled, in particular acute-angled contour, which increases the surface pressure on the attachment. By pressing the attachment in the sealing shoulder this acts simultaneously as a form-locking element between the attachment and the plastic hollow part, which increases the withdrawal forces of the two parts to each other.
  • the support element is mounted on the plastic hollow part without play, in particular embedded without play.
  • a plastic hollow part 1 with a connection contour 10 and an attachment 2 mounted thereon is shown in the form of an elastomer hose.
  • the elastomeric hose 2 is pushed over the connecting contour 10, which is formed, for example, as a connecting piece or a flange, and serves to connect the elastomer hose 2 to the plastic hollow part 1.
  • the plastic hollow part 1 is preferably designed as a plastic blow-molded part and has an internal cavity 10a, which serves in particular for the passage of fluids, such as intake air or the like.
  • an end-face securing contour 3 is provided at the connection contour 10. hen, which is formed in the illustrated embodiment as a peripheral edge.
  • the securing contour 3 can also be designed in the form of individual, radially projecting projections, so that no circumferential edge, but interrupted web portions on the front side of the connection contour 10 are present.
  • the securing contour 3 can be molded together with the plastic hollow part 1 in the blow mold or applied subsequently, for example by thermal embossing or by injection molding.
  • a sealing shoulder 4 in the present case a circumferential sealing shoulder 4, is formed on the plastic hollow part 1 and the connecting contour 10.
  • the peripheral sealing shoulder has a triangular cross-section and has a certain radial extent of the connection contour 10.
  • a support element 5 in the form of a support ring on the connection contour 10 is arranged.
  • the support ring 5 rests on the outer circumference on the connection contour 10 and serves to receive radially acting forces.
  • the support ring 5 may be mounted in a press fit outside on the plastic hollow part 1, the backup contour can also be omitted. It is also possible that the support ring 5 is formed outside on the connection contour 10 by the support ring 5 is inserted before blowing the plastic material into the blow mold and at least partially surrounded by the plastic material.
  • the attachment 2 in the form of the elastomeric hose extends over the securing contour 3, the support ring 5 and the peripheral sealing shoulder 4 and is held on the connection contour 10 via a clamp 6, in the present case a hose clamp.
  • the hose clamp 6 is arranged in the present embodiment, that it is arranged axially above the sealing shoulder 4 and presses the attachment 2 in the direction of the sealing shoulder 4. Characterized the acute-angled sealing shoulder 4 is pressed into the attachment 2, so that a partial positive engagement is generated, which increases the withdrawal forces between the attachment 2 and the plastic hollow part 1.
  • the hose clamp 6 is likewise arranged above the support element 5, so that the attachment 2 is clamped between the support element 5 and the hose clamp 6.
  • connection contour 10 Due to the very precise definition of the outer contour of the connection contour 10 by the blow molding tool, a reworking of the contact surface of the support ring 5 on the connection contour 10 will generally not be necessary.
  • the support ring 5 can be pushed onto the connection contour 10 from the outside until it rests against the sealing shoulder 4.
  • the security contour 3 then secures the support ring 5 against falling or slipping down during transport prior to assembly.
  • connection contour 10 As an alternative to a hose clamp, other securing elements can also be provided which secure the attachment 2 on the connection contour 10 and exert radially acting forces on the connection contour 10.
  • the securing contour 3 can also be applied after the support ring has been pushed on, for example by thermal embossing.
