Definitions
- the present invention relates to a hose clamp with a clamp band extending along a circumferential direction and with a tensioning device for tensioning the clamp band.
- the hose clamp has a clamping device with which a clamp band can be clamped, for example, around a hose end or the like.
- the clamping device has for this purpose a clamping screw which is rotatably received in a housing of the clamping device.
- the clamp band that has on its outer side a corresponding engagement geometry for the thread, in the housing of the clamping device be confiscated.
- Hose clamp accordingly and radial clamping forces are generated.
- Material elasticity of the clamp band is not sufficient, for example, in a temperature-induced expansion of the pipe end or the like
- the hose clamp therefore has several items that must be joined together during manufacture.
- the wave spring, the wave spring bridge and a section of the clamp band must also be connected to each other.
- the corrugated spring bridge serves to rest against the hose or pipe, so that the system is not interrupted by the corrugated area of the corrugated spring. Overall, this results in a complex construction with several items that must be provided for the production of the hose clamp and connected to each other.
- DE 31 30 092 A1 shows an alternative embodiment of a hose clamp with a clamp band extending along a circumferential direction and with a tensioning device for tensioning the clamp band, wherein the clamp band itself has a corrugated structure.
- the object of the invention is the development of a hose clamp (hereinafter:
- the clamp should have a tight fit over a longer period of time and at changing temperatures. In particular, high tightness should be ensured.
- This task is performed starting from a clamp with one extending along one
- Circumferentially extending clamp band with a first edge and a
- Clamping device for tensioning the clamp band at the first end
- the clamp band has a radially flared first structure at the first edge and at the second edge a radially flared second structure.
- the invention is based on the idea of providing a modification to the corrugated structure according to the prior art in that the first structure and the second structure each extend in the axial direction, the first structure being in communication with the first edge and the second structure communicates with the second edge.
- the first and the second structure additionally extend in the radial direction. This creates the opportunity for the clamp band, over the entire
- Circumferential direction by means of an existing geometry between the structures to create a contact against the surface of the body over which the clamping force of the
- the first structure and the second structure are each formed by formations which repeat periodically along the circumferential direction.
- formations which are arranged on the first edge form the first Structure and formations disposed on the second edge, the second structure.
- a regular surface of the clamp band is achieved with homogeneous elastic properties.
- a uniform transfer of the clamping force is achieved on spanned body when clamping the clamp.
- the radial extent of the formations is variable in the axial direction.
- the formations extend radially outward on the outside of the clamp band. Because the formations in
- Clamp bands for stresses in the circumferential direction along the axial direction are different.
- surfaces of the bodies to be clamped which are not coplanar with the clamp band are detectable to a limited extent by the tensioning of the clamp band.
- Clamp bands extend, wherein the formations of the first structure and the formations of the second structure in the circumferential direction are mutually arranged.
- An advantage of this embodiment is that the formations of the structures are arranged regularly, although the formations of the structures are arranged either on the first or on the second edge of the clamp band. Due to the regular arrangement of the formations, the distribution of the elastic properties of the clamp band in the region in which the structures are arranged is likewise homogeneous. This will be a very uniform
- the structures are preferably arranged in a structural section of the clamp band. This advantageous embodiment makes it possible for the clamp band more
- the clamp band may have a portion used to tension it.
- the first structure of the second edge and the second structure of the first edge each have a Randbeabstandung.
- the formations of the first structure and the formations of the second structure in the circumferential direction in each case an intermediate spacing on each other.
- the edge spacings and the intermediate spacings within the structural section form a planar geometry of the clamp band.
- This planar geometry is in contact with the surface of the body on which the clamp is applied.
- the compression, which is exerted by the tensioning of the clamp on the body, is advantageously transmitted through the planar geometry.
- a uniform determination of the body is achieved with the clamp, the clamp always rests over the entire circumference.
- an elastic second body for example a hose
- a first body for example a flange
- the clamp band has at least one section without one of the structures.
- the at least one portion without one of the structures has a threaded embossment which can be arranged at the second end of the clamp band.
- the second end of the clamp band can run into the clamping device at the first end of the clamp band, if this for clamping the
- the clamping device may comprise a clamping screw and a housing, so that the entire clamp with the clamp band of at least three structural components is designed to work.
- the three structural components are finally formed by the clamping screw, the housing and the clamp band, which can be connected to each other by appropriate joining methods, in particular stamping and bending processes.
- Embodiment can be provided that the clamping device is formed integrally with the clamp band and can be formed by punching-bending method of the clamp band. Due to the one-piece design of the clamp band with the
- Clamping device or the production of an at least three-part clamp in one Punching-bending process facilitates the manufacture of the clamp, so that advantageously the manufacturing costs of the clamp are low.
- the formations of the structures are formed as conical peripheral sections.
- the structures at the respective edges to which they abut essentially have a waveform.
- the wave crests extend in the radial direction to the outside.
- the troughs do not extend inward in the radial direction.
- the structures may also have other shapes at the respective edges, e.g. a triangular shape or a
- the clamp band then has bulges, which are due to the shape of the structures on the respective edge and form the formations of the structures.
- the formations of the structures each have a notch.
- the notches form material recesses and are produced in a particularly preferred spanok.
- the elasticity of the clamp band is further increased.
- the clamp has a central notch at least in sections along the central axis. In this case, provision is made in particular for the notch to have a width along the central axis which can be interpreted as a function of the desired stiffness matrix of the clamp.
- the width of the notch is less than or equal to three times the thickness or the material thickness of the clamp band.
- the notch is configured such that the surface of the body to be clamped can not be clamped by the edges of the notch running parallel to the central axis.
- Clamp bands is in particular between 0.1 mm and 1, 5 mm, preferably between 0.4 and 1, 0 mm and particularly preferably between 0.6 and 0.8 mm.
- the clamp along the central axis is at least partially separated along a separation path.
- this results in a certain flexibility of the clamp in the axial direction. This flexibility allows the clamp to better conform to an uneven surface of the body to be clamped.
- the clamp has two places along the central axis at least partially on separation paths, particularly preferably, the clamp at three points along the central axis at least partially on separation paths.
- a central axis at least partially on separation paths.
- Notch is formed at least in sections along the central axis, which penetrates the structures in particular.
- the notch increases the flexibility of the clamp in the axial direction.
