Abstract
Workpieces that have various elements for joining in accordance with the prior art often have an undesirable play when in the mounted state or are costly to produce.
A workpiece (1) according to the invention has a recess (5) that is compressed by means of a plastic deformation, which reduces one dimension or an inner diameter of the workpiece (1) and thus joins this workpiece (1) to an inner piece (18) in a positively and frictionally engaging manner.
Description
- The invention is based on a workpiece as generically defined by the preamble to claim 1.
- So-called flared joints are known in which two workpieces are first slid one into the other so that the one workpiece rests against a stop of the other and protrudes above it with an edge, the flared edge. The joint is produced through flanging, the flaring, of the flared edge onto the one workpiece so that the workpieces are joined in a positively engaging manner. In this type of joint, two workpieces are required and it is only possible to achieve a definite contour of the flanging of the flared edge through costly measures. A flared edge must often be provided around the entire circumference of a workpiece. After the joining, there is thus often an axial and/or radial projection.
- Another known type of joint is the so-called dovetail joint in which tolerances must be very strictly maintained. In the joining process, a projecting part and a recess of the dovetail joint are placed one over the other and are then pressed one into the other, as described in DE 39 25 365 A1. In the process of this, the parts must be placed one over the other and are not slid one into the other, thus rendering it necessary to make the parts that are to be connected somewhat longer and thus increasing the tolerance, for example of an inner diameter of a tube element.
- DE 38 15 927 A1 has disclosed a joining of shaped parts by means of elastic securing arms. This design, however, inevitably leaves gaps between the shaped parts. It is not possible to produce a gap-free transition between the shaped parts.
- U.S. Pat. No. 2,283,918 has disclosed a joining method for a metal band in which a tab is caulked into a recess. A bulky tool and powerful forces are required to produce the caulking.
- U.S. Pat. No. 3,502,922 has disclosed a detent connection that is comprised of an insert tab and a recess. The insert tab is slid into the recess in order to produce a joint. The regions around the recess are designed to be elastic so that they can move outward and then spring back together when the insert tab is slid into the recess. This results in a certain amount of play between the parts.
- Another possibility for mounting a ring onto an inner piece is the shrink-fitting technique. In this instance, the inner piece, for example, is cooled so that it shrinks. Only then can the ring be slid onto the inner piece. When the inner piece warms up again, a press fit is produced between the inner piece and the ring. The method, however, is costly and has the disadvantage that the joint comes apart if the ring and the inner piece cool or heat differently.
- The workpiece according to the invention, with the characterizing features of
claim 1, has the advantage over the prior art that a workpiece can be simply mounted onto a component and there is no tolerance. After the joining process is complete, the workpiece has neither an axial nor a radial projection. - Advantageous modifications and improvements of the workpiece disclosed in
claim 1 are possible by means of the measures taken in the dependent claims. - If the workpiece is a tube element, then it can advantageously be mounted onto an inner piece.
- It is also advantageous for the recess to be designed similar to the shape of a dumbbell because this simplifies the plastic deformation for tolerance-free mounting.
- The workpiece is advantageously comprised of metal because metal has a favorable capacity for plastic deformation.
- An exemplary embodiment of the invention is shown in a simplified fashion in the drawings and will be explained in detail in the subsequent description.
- FIG. 1 shows a detail of a workpiece according to the invention, in the unmounted state,
- FIG. 2 shows a detail of a workpiece according to the invention, which is plastically deformed,
- FIG. 3a shows how the workpiece according to the invention is slid over an inner piece, and
- FIG. 3b shows how a workpiece according to the invention is mounted onto the inner piece.
- FIG. 1 shows a partial section of a
workpiece 1 according to the invention. Theworkpiece 1 can be a sheet metal band extending along alongitudinal axis 2 or a sheet metal ring and has at least onerecess 5. Therecess 5, which is embodied for example with a circumferentially closed border, has the shape, for example, of a dumbbell or a spool. - It is possible for the
recess 5 to have any other shape. Therecess 5 is designed so that in a strip-shaped edge region 7 of theworkpiece 1, there is a greaterempty volume 9 than in amiddle region 8 of therecess 5. - In the
middle region 8, there is a connectingsegment 11 that extends perpendicular to thelongitudinal axis 2, which connectingsegment 11, in the direction of thelongitudinal axis 2, has a thickness or, if therecess 5 is circular, a diameter d, which is sized so that it is almost or completely compressed, i.e. becomes zero, when theworkpiece 1 is mounted. The connectingsegment 11 connects the one larger empty volume in oneedge region 7 to the other larger empty volume in theother edge region 7. - FIG. 2 shows a
workpiece 1 according to the invention, which is plastically deformed. Starting with theworkpiece 1 in FIG. 1, atool 12 is placed against it, for example in eachedge region 7, which tool exerts a force on theworkpiece 1 in adeforming direction 13 lateral to thelongitudinal axis 2 and compresses theempty volume 9 of therecess 5. This causes theworkpiece 1 to contract in the direction of thelongitudinal axis 2 in a dimension, a joiningdirection 15, perpendicular to thedeforming direction 13. Theempty volume 9 and the connectingsegment 11 are almost or completely gone, for example. Since an external force exerted by thetool 12 can only be applied in anedge region 7 of theworkpiece 1, it makes sense to design therecess 5 so that the greatest proportion of theempty volume 9 of therecess 5 is provided in thisedge region 7 because then a plastic deformation requires only minimal forces and the plastic deformation can therefore be produced with considerable ease. - FIG. 3a shows how a
workpiece 1 is slid onto aninner piece 18. For example, theworkpiece 1 is a tube element 21 and theinner piece 18 is a coil body of an electric machine, the tube element 21 in this instance constituting a magnetic yoke element. In comparison to a two-part tube element with a continuous connecting point according to the prior art, the tube element according to the invention has the advantage that there is no gap-encumbered transition that interrupts the flow of the magnetic field in the yoke element. - The tube element21 has an inner diameter that is greater than the outer diameter of the
inner piece 18. When the tube element 21 is plastically deformed by thetool 12, the tube element 21 rests snugly against theinner piece 18 and is thus fastened to the inner piece 18 (FIG. 3b). - FIG. 3b shows a tube element 21, which is fastened to an
inner piece 18. Thetool 12 has deformed the tube element 21, thus compressing therecess 5. This causes the tube element 21 to contract in a joiningdirection 15, i.e. in the case of the tube element 21, the inner diameter of the tube element 21 becomes smaller. The plastic deformation is executed until the inner diameter of the tube element 21 approximately corresponds to the outer diameter of theinner piece 18 and is deformed even further so that a sufficient force is produced, which presses the tube element 21 onto theinner piece 18.
