Definitions
- the invention relates to a method for molding a spinning or twisting ring according to the preamble of Claim 1 as well as on a non-cutting spinning or Thread ring, with T-shaped profile.
- flange ring uses its parts as a flange and the bridge. Those surfaces on the flange with which the runner cooperates in spinning or twisting, and their profile accuracy and surface quality from Significance are hereinafter referred to as functional areas or functional profiles.
- Known methods for forming a flange ring exist usually from machining operations. Went out is made of tubular rods made of ball bearing or case hardening steel. On multi-spindle machines or CNC machines a corresponding ring profile is worked out from a turning blank, the turning blank being formed by parting off must become.
- a generic method, in which from steel a blank disc is punched out, the blank disc below Formation of a base area deep-drawn in a cup shape, and A circular disc is punched out centrally on the base area is known from GB-A-692 399.
- the object of the invention is to create a method to form a high quality flange ring that both regarding procedural operations as well as regarding Material expenditure for the same is economical.
- the invention lies primarily in the knowledge that exclusively by strip forming, i.e. by drawing and Press operations, a flange ring with sufficient material transfer to form the flange.
- the finished flange ring form is the manufacture corresponding quantities extremely cost-effective. machining Edits are unnecessary, at least to the extent that than the essential dimensions of a flange ring ISO 96-1: 1992 (referred to there as the T-ring) are affected.
- the forming operations themselves, as well as the punching operations, can be carried out without reclamping.
- the punching process to separate the circular disc from the web side done here. So the shear edge comes inward projecting flange shoulder to lie on the top of the flange, i.e. into a material zone that, even after pressing, not in an essential part of the flange and there is no load on the runner during operation experiences.
- edge areas of the Flange given predetermined functional profiles. With that leaves post-processing by turning or grinding avoid entirely. It has been shown that with these Operations accurate profiling, as well as smooth Surface of the functional surfaces is accessible. Avoidance related post-processing by turning or grinding again saves considerable costs to. Finally, the extrusion works immediately on improving the Wear properties.
- the invention also includes one by cold working completely non-cutting spinning or twisted ring, which is full-walled according to the invention and also through a special distribution of the grain sizes on the ring cross-section distinguished.
- a partially punched-out round disk is held as a blank disk 12 by means of a net holder 14a, 14b obtained by net punching.
- a hump 16 is formed in the center of the blank disc 12, which forms the basis 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 , an at least approximately cylindrical wall being formed as a 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 because the outer diameter of the Edge on the blank 12a becomes smaller by the second deep-drawing process.
- the tool 36 shown in FIG. 4, having a die 32 and a punch 34 , is used for ironing the blank 12b and for pressing the hump 16 shown in FIG. 2 flat.
- the web area 30a is stretched on the one hand, so that whose wall thickness 38 is reduced to 0.8 mm, for example.
- a controlled material flow in the direction of the arrow 40 according to FIG. 5 takes place from the center into the edge region 42 .
- an annular recess 44 is arranged in the die 32 .
- the blank 12b is still connected to the steel strip 10 according to FIG. 1 by means of the net holder 14a, 14b in this method step.
- the material shift into the edge area 42 serves as a preliminary stage for the formation of an annular flange.
- the punching tool 54 shown in FIG. 6 and having a die 48 and a double punch 50 , 52 is used in order first to punch away the edge 58 and second to punch out a circular disk 56 from the bottom area 57 of the blank 12c forming the flange side . After the circular disk 56 has been punched out, a radially inwardly projecting flange shoulder 59 remains on the bottom region 57 .
- 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 net holder 14a , 14b .
- the holding of the blank disc 12 in the respective process step on the strip steel 10 served for the feed to the subsequent work station.
- FIG. 7 shows a detail in an enlarged representation of the cutting edge 60 after the edge 58 has been punched away.
- the embossing and deep-drawing tool 68 shown in FIG. 8 having a die 62, a core punch 64 and a ring punch 66 , is used on the blank 12d for stamping or smoothing the non-functional cutting edge 60 (FIGS. 7, 9), for tapering the outside diameter of the web area from 30a (FIG. 6) to 30b (FIG. 8) by deep drawing and for preforming the flange region 70.
- the web region 30b is also compressed during this process.
- the die 62 has an annular recess 71 for receiving and preforming the flange region 70 .
- the flange region 70 of the blank 12d consists of the radially inwardly projecting flange projection 59 and a radially outwardly projecting flange projection 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 cutting edge 60 of the blank 12d and for tapering its outer diameter.
- the stamping 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 area 70 which is connected 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 embossing 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 extruded from the flange region 70 , both the radially inwardly projecting flange shoulder 59 and the radially outwardly projecting flange shoulder 73 being rounded.
- 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 installation position.
- the flange approaches 59, 73 convexly shaped functional profiles 72, 73a between the web area 30b and the flange top.
- the flange ring 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 so produced Flange rings are made of full material instead turned flange rings ready for use.
- the also inventive, non-cutting and complete spinning or twisting ring produced by cold forming T-profile, comprising a web and a flange, approximately according to Fig. 11 differs from that by machining rings produced once by the material of the Bridges practically connected over its full cross section merges into the flange. At least this is before a heat treatment, such as hardening occurring, noticeable on the course of the fibers.
- Such a full-walled ring is therefore not only different from e.g. rings produced solely by turning or by shaping and turning (DE-A1-195 03 321), in which fibers be cut, but also by the chipless manufactured rings in which the flange through Bending steps were molded.
- DE-A1-195 03 321 in which fibers be cut, but also by the chipless manufactured rings in which the flange through Bending steps were molded.
- GB-PS 692'399 directed.
- a full-walled flange ring according to the invention produce is usually one of strip steel thermoformable quality, one Deep drawing deformation followed by compression and compression steps, by means of which the flange is molded. After Such a ring is shaped by case hardening and Polishing finished.
- This also leaves the service life of the Ring favoring greater Brinell hardness on the flange surface to reach. It can be said generally: that the grain size in the flange (88) from the inside (90) to Surface (92) and towards the web (86) by at least 20% decreases.
- the mean size difference is about a factor of 2 or greater.
