Definitions
- the invention relates both to assembly nuts and to methods for producing assembly nuts, which consist of the nut body and pressure plate, the nut body having a drive part, such as a polygon, for engaging a tool and a contact area which when tightened in Can be brought into contact with the support surface of the pressure plate arranged captively on the nut body, which has a central recess into which a neck integrally formed on the nut body extends at least partially axially, the neck having a projection to form a captive connection, which part of the pressure ring is radial covers or reaches behind.
- a drive part such as a polygon
- the pressure plate is in front of the Assembled with the nut body by cold forming, subsequent turning and subsequent tempering.
- the nut body itself has a hexagon drive part, as stipulated by the DIN standard for nuts.
- the present invention was based on the object of being able to manufacture assembly nuts of this type more cheaply, the number of manufacturing processes reduce and optimize and continue to reduce the use of materials. In addition, the transferable torques should be increased while maintaining or improving the other essential usage properties.
- the invention initially achieves at least part of this object by providing that cold forming, turning and tempering are eliminated in the manufacture of the pressure plate and instead the pressure plate is brought to its final shape by means of a single forming process before being joined to the nut body brought.
- the forming process is carried out in the form of a hot pressing process, which can be carried out in a multi-stage tool.
- the hot pressing process according to the present invention is characterized in turn by the fact that it only includes a one-time heating process; it can be particularly advantageous if the cooling of the printing plate takes place in a targeted or controlled manner after the hot forming, the cooling of the printing plate taking place in a predetermined time - Temperature grid can be done. This makes it possible for a structure of the pressure plate corresponding to a separate heat treatment, such as “tempering”, to be produced by simultaneous cooling from the heating used in the forming process.
- a printing plate according to the method according to the present invention not only the cold forming and turning can be omitted, but also the tempering, which overall results in considerable cost savings compared to the previous manufacturing methods.
- the targeted cooling can take place, for example, by means of air and / or with at least partial use of a liquid medium.
- the targeted cooling achieves a property similar to tempering, namely a strength of the material that is comparable to the strength of the previous manufacturing process, in which a separate tempering process was provided, as well as the corresponding structure.
- These properties which are at least approximately equivalent to tempering, are therefore not achieved by an additional heating process, but rather by cooling from a hot forming process, which is required for shaping anyway.
- the assembly nut according to the invention is distinguished by the fact that it is not cold-worked, not machined and is not subjected to its own starting process.
- the following contours of the pressure plate are thus after a heating process ⁇ outer diameter ⁇ the contact area facing away from the nut body, which can also be concave and which is used for contacting the rim ⁇ the central recess together with its for the purpose of holding the pressure plate on the Nut against the contact area of the pressure plate to radially widened contour, which can be conically widened or formed as an undercut ⁇ the support surface provided for contacting the nut body, which can be conical - convex and the conicity of which can be steeper than that of the contact region ⁇ the transition region between the support surface and the outer diameter
- the pressure plate is made of a steel with a higher carbon content than the 34 CrMo 4) usually used for such pressure plates, namely, for example, 42 CrMo 4 , which is at least not significantly more expensive than the former.
- Assembly nuts can be improved according to further features of the invention and at least solve task areas of the type mentioned at the outset, namely e.g. increase the transferable torques, continue to achieve a more even contact pattern when tightening the nuts and a better torque distribution, e.g. can be achieved by a more even material distribution over the polygon and even a reduction in cost due to the reduced use of material.
- such assembly nuts can have fewer than six, six or more than six force application elements, such as engagement cams or surfaces, but insofar as that
- the drive part that is to say the nut body has six force application elements, deviate from a normal hexagon, as provided by DIN for such nuts.
- the drive part is an outer round profile, for example a six, eight or other outer round profile.
- These outer-round profiles of the mother part can also have the shape of a Torx® profile or a Torx®-like profile.
- Torx® profiles or Torx®-like profiles have so far only been used in connection with screws, with an inner or outer profile on the screw heads.
- the invention therefore also relates to nuts with an outer round profile, such as with Torx® or Torx®-like ProftJ in general, and also with assembly nuts in particular.
- Invention nuts with an outer-round profile or Torx® or Torx® - similar profile are characterized by the fact that they do not have straight flanks that connect the individual axially extending corner edges, but they have round edges and radial indents or axial between them running grooves. Compared to comparable polygonal profiles, these profiles ensure a considerably greater torque transmission, a reduction in radial forces, and an improved attack by the tools, because there is a much more even contact pattern when tightening.
- FIG. 1 shows an assembly nut according to the prior art in section along the line I-1 of FIG. 2, which shows a plan view of such an assembly nut
- FIG. 3 shows an assembly nut according to the invention in section along the line III-III of FIG. 4, the latter showing a top view of this assembly nut
- FIG. 5 shows a further assembly nut according to the invention in section along the line VV of FIG. 6, the latter showing a plan view of such a nut
- Figure 7 shows another embodiment according to the invention in section along the line Vll-Vll of Figure 8, which in turn shows a plan view.
- Assembly nuts according to the prior art according to Figures 1 and 2, as also described in DE-OS 196 50 453, have a nut body 1, to which a pressure body 2 is captively attached, the nut body having a drive part that is designed as a hexagon 3 for attacking a tool.
- the nut body 1 also has a contact surface 4, which can be brought into contact with the support surface 5 of the pressure plate 2, which is arranged so that it cannot be lost on the nut body.
- This pressure plate has a central recess 6 into which a neck 7 integrally formed on the nut body is axially at least partially stretches in, the neck to form a captive connection has a molded part 8 in the form of a widening 11 which partially radially covers or engages behind the pressure ring.
- the pressure plate 2 is first produced by cold forming before being joined to the nut body 1, then at least the support surface ⁇ 'and the contact area 9 with which the pressure plate comes to rest on the rim are rotated. Thereafter, the pressure plate consisting of 34 CrMo 4 in the prior art is remunerated. After assembling printing plates 2 and Nut body 1 of the neck 8, which initially has a smaller diameter than the central recess, is widened radially outward, and the pressure plate is thus secured to the nut body.
- the pressure plates 2a, 2b and 2c of FIGS. 3 to 8 consist of a steel having a higher carbon content than the pressure plate according to the prior art and FIGS. 1 and 2, advantageously of 42 CrMo 4 .
- These pressure plates 2a, 2b and 2c are brought into their final shape by means of a single forming process, expediently by means of a hot pressing process, and expediently in a multi-stage follow-up tool, the hot pressing process including a one-time heating process, the cooling of the pressure plate after the hot forming being targeted or Controlled takes place according to a predetermined time-temperature grid and thus a structure of the printing plate corresponding to a “tempering” by this targeted cooling from the heating used in the forming process. This can be done by targeted and controlled cooling by air or by at least partial application of a liquid medium.
- the existing contours of the pressure plate - outer diameter 10 - The contact area facing away from the nut body, with which the pressure plate comes to rest on the rim and which can also be conical, ie concave, can be formed - the central recess 6 together with it for the purpose of holding the pressure plate on the nut against the contact area 9 of the Pressure plate 2 for the radially widened contour 11 - the support surface 5 provided for contacting the nut body, which is conical or convex and the conicity of which is steeper than the conicity which can be provided on the contact region 9 - the transition region between the support surface 5 and the outer diameter 10
- the nut body 1 is designed with six engagement elements 12a in the form of an outer round profile. It is a "Tooc" ® corresponding or modified or similar profile.
- the nut body according to FIGS. 5 and 6 has eight force application elements 12b in the form of an outer round profile.
- the ratio of the outer diameter A to the core diameter Bb is smaller than the ratio in the exemplary embodiment 3 and 4, namely less than 1.3, while in FIGS. 3 and 4 the ratio of the outer diameter Aa to the core diameter B a is approximately 1.35.
- the engagement elements 12c are designed as a 12-point and the ratio of the outer diameter Ac to the core diameter B c is less than
- the pressure plate is calibrated before being joined to the nut body in a tool or immediately before an assembly tool at least at the edge 13 of the central opening, which could come into contact with the nut body when tightened, or at least is calibrated there a ridge that may have been deformed.
