Definitions
- the invention relates to a method for forming a spinning or twisting ring according to the preamble of claim 1 and to a spinning or twisting ring produced without cutting, with a T-shaped profile.
- flange ring is used in connection with the T-shaped profile, the parts of which are referred to as flange and web.
- Those surfaces on the flange with which the rotor interacts in spinning or twisting operation and whose profile accuracy and surface quality are important are referred to below as functional surfaces or functional profiles.
- machining operations usually consist of machining operations. This is based on tubular rods made of ball bearing or case hardening steel.
- CMC machines multi-spindle machines or CMC machines, a corresponding ring profile is worked out from a turning blank, the turning blank having to be formed by parting off.
- the object of the invention is to provide a method for forming a high-quality flange ring, which is economical both in terms of process operations and in terms of material expenditure for the same.
- the invention lies primarily in the knowledge that a flange ring with sufficient material displacement to form the flange can be achieved exclusively by strip forming, i.e. by pulling and pressing operations.
- Profiling on the flange is affected, this can be carried out by turning or grinding, in the latter case also after case hardening. Compared to the manufacture of flange rings by machining, there is considerable material savings.
- the punching process for separating the circular disk from the web side is carried out.
- the shear edge comes to rest on the inwardly projecting flange shoulder on the top of the flange, i.e. in a material zone which, even after pressing, does not lie in a functionally essential part of the flange and is not subjected to any stress by the rotor during operation.
- the invention also encompasses a spinning or twisting ring which is produced without cutting by cold working and which, according to the invention, is full-walled and is also distinguished by a special distribution of the grain sizes over the ring cross section.
- FIG. 1 shows a section of a steel strip with a pre-punched blank disc held therein by means of a net holder
- FIG. 3 shows a second deep-drawing process for forming the at least approximately cylindrical part of the ring blank
- FIG. 5 shows a detail of the edge area according to FIG. 4 in an enlarged view
- FIG. 7 shows the edge region opposite the flange region with the punched edge according to FIG. 6, in an enlarged representation
- 8 shows an embossing process of the non-functional stamping edge, tapering of the outside diameter by drawing, controlled material flow into the flange area and reduction of the web length to increase the material availability in the flange area
- FIG. 11 shows an exemplary embodiment of a flange ring according to the invention.
- a partially punched-out round disc is held as a blank disc 12 by means of a mesh holder 14a, 14b obtained by mesh punching.
- a mesh holder 14a, 14b obtained by mesh punching.
- a hump 16 is formed in the center of the blank disc 12, which forms the base for a blank for producing a spinning or twisting ring.
- the first deep-drawing tool 22 shown in FIG. 2 and having a die 18 and a stamp 20 is used to form the hump 16.
- the blank disc 12 shown in FIG. 2 is formed into a cup-shaped blank 12a. wherein an at least approximately cylindrical wall is formed as the web area 30.
- the blank 12a is still connected to the steel strip 10 by means of the net holder 14a, 14b shown in FIG. 1, but the webs of the net holder 14a, 14b are pulled apart compared to the illustration in FIG. 1, since the outer diameter of the edge on the blank 12a becomes smaller as a result of the second deep-drawing process.
- Tool 36 having a punch 34 is used for ironing the blank 12b and for pressing the hump 16 shown in FIG. 2 flat. With this tool 36, the web area 30a is stretched on the one hand, so that its wall thickness 38 is reduced, for example, to 0.8 mm.
- the double stamp 50, 52 can be designed as a follow-up tool, or it can be stamps which can be actuated separately from one another.
- the blank 12c is separated from the steel strip 10 by punching out the edge 58.
- the punching out of the circular disk 56 from the web side serves for rough shaping of the inner ring diameter.
- the blank 12c was connected to the steel strip 10 shown in FIG. 1 by means of the mesh holder 14a, 14b.
- the holding of the blank disc 12 in the respective process step on the strip steel 10 was used for the feed to the subsequent work station.
- FIG. 7 shows a cutout in an enlarged representation of the cutting edge 60 after the edge 58 has been punched away.
- the web area 30b is also compressed during this process.
- the die 62 has for receiving and preforming the
- Flange region 70 an annular recess 71.
- the flange area 70 of the blank 12d consists of the radial one inwardly projecting flange shoulder 59 and a radially outwardly projecting flange shoulder 73.
- the core punch 64 essentially serves to hold the blank 12d on the die 62 and to fix its inside diameter.
- An annular embossing and drawing edge 66a arranged on the inner edge of the ring stamp 66 according to FIG. 9 serves both for embossing or smoothing the cut edge 60 of the blank 12d and for tapering its outer diameter.
- the embossing and deep-drawing process results in a controlled material flow from the web area 30b into the flange area 70.
- the length of the web area 30b decreases.
- the compression of the material in the flange region 70, which is associated with the material flow and is thereby solidified, is particularly advantageous. As a result of the reduction in the diameter of the web area 30b, the material in this can also be compressed.
- FIG. 9 illustrates the continuous stamping and deep-drawing process in which the ring stamp 66 is moved in the direction of arrow 74 in three successive individual images.
- the tool 76 shown in section in FIG. 10 has a die 78, a core punch 80 and a ring punch 82. It essentially serves for the final shaping of the functional surfaces of the flange ring 84.
- the T-shaped profile of the flange ring 84 is formed by a web 86 and a flange 88.
- the flange 88 is formed by extrusion from the flange area 70 and rounded on both the inside and the outside.
- flange 88 The flattened top of flange 88 is the downward side in the drawings because the flange ring is directed downward with flange 88 during the molding process, as opposed to its installed position.
- the flange attachments 72, 73a are given convex-shaped functional profiles between the web area 30b and the upper side of the flange.
- the flange ring is hardened or surface hardened.
- the molding method according to the invention is suitable for flange rings of different sizes and enables considerable material and cost savings.
- the flange rings produced in this way can be used instead of flange rings turned from solid material.
- the spin-free or twisted ring with T-profile also according to the invention, made from cold deformation and completely produced by cold working, comprising a web and a flange, for example according to FIG. 11, differs from the rings produced by machining in that the material of the web is practically over the full cross section of which merges into the flange. This can be established on the course of the fibers at least before a heat treatment, such as, for example, during hardening.
- a full-walled ring not only differs from the rings produced, for example, by turning, in which fibers are cut, but also from the ones that are also chipless Manufactured rings in which the flange was formed by bending steps.
- strip steel of a deep-drawing quality is generally assumed, with deep-drawing deformation followed by compression and compression steps by means of which the flange is formed. After shaping, such a ring is completed by case hardening and polishing.
- Cross sections have a relatively fine grain in comparison to the flange core, where coarse grain is mostly to be found throughout. This also allows a greater Brinell hardness on the flange surface which favors the service life of the ring. It can generally be said that the grain size in the flange (88) decreases by at least 20% from the inside (90) to the surface (92) and to the web (86). As a rule, the mean difference in size is about a factor of 2 or greater.
