Definitions

  • a profile does not necessarily have to have a constant thickness or material thickness over its circumference.
  • the thickness can be partially reduced and thus material can be saved.
  • a partial reduction in thickness by a single-stage rolling in cold rolling on a strip-shaped rolling is not useful because due to the friction transverse to the roll and the stiffness of the flat rolled material reduction is converted only in an extension in the longitudinal direction or in the feed direction and a material consolidation. This leads to internal stresses and strong distortions of the rolling stock.
  • a disadvantage of the known solution is that this cold rolling allows only for profiles with a trapezoidal cross-section reduction of the required stations in the rolling mill for the production of the profile. Due to the inclined forming regions, the pressure rolling elements have different effective diameters at their forming regions, which leads to abrasion and thus to undesired traces in the profile.
  • From the US 3,209,432 is a cold rolling process for producing a profile of a one-piece rolling stock as a starting material by means of the forming forming regions of rolls known, wherein the forming regions are each aligned parallel to the axis of rotation of the corresponding roll.
  • the starting material is shaped in the widthwise direction of the starting material by the forming regions oriented parallel to the axis of rotation of the rolls, and then bent into the desired profile shape.
  • the DE 33 43 709 A relates to a method for forming a frame part for use in a motor vehicle for receiving bending stresses acting thereon, comprising the steps of: rolling a metal sheet to form a recess on a surface of the metal sheet so as to obtain a tapered portion extending longitudinally of the metal sheet, wherein the thickness of the metal sheet near the longitudinal centerline is smaller than near each side, and bending the rolled metal sheet in the longitudinal direction to form a U-section having a land and legs on opposite sides of the web are bent in the same direction.
  • the JP 61-027103 describes a forming process in which successively act several different roles on a workpiece.
  • From the EP 1 847 333 A1 is a method for reducing the thickness of one-piece rolling produced, in which the starting material by means of the Walzgutbreite different depths penetrating into the starting material rolls in the width direction, characterized in that by means of at least two oppositely arranged profile rollers longitudinal waves are rolled, the wave crests and wave troughs themselves extend parallel to the longitudinal extent of the rolling stock, and the area provided with longitudinal waves is then flat-rolled over at least two oppositely arranged rollers.
  • the nearest one EP 1 847 334 A1 describes a method for reducing the thickness of one-piece rolling stock, in which the starting material by means of Walzgutbreite different deep penetrating into the starting material rolls in the width direction is transformed, wherein provided in a first step, the rolling stock with at least two, at a distance parallel to the longitudinal extent bends is and in a further step by means of two oppositely arranged rollers, each having at least one obliquely arranged to the axis of rotation of the rollers Abgarge Scheme, the area between the bends in the thickness is reduced.
  • the object of the invention is to provide a cold rolling process in which there is an improvement in the expansion of the one-piece rolling stock and an improvement in the economic efficiency of the process.
  • the invention is characterized in that the cold rolling method comprises a further method step in which the at least one non-thickness-reduced, bent section is bent back into a profile prior to further processing of the width-converted and bent starting material so that the at least one before or during the thickness reduction formed bend is canceled before forming the reduced thickness starting material to the desired profile again.
  • a bend in the starting material is formed and thus created a further extending in the rolling or longitudinal edge in the starting material or in one piece rolling, which compared to the distance from the to be created thickness-reduced area to the free, in rolling or extending in the longitudinal direction edge of the one-piece rolling a smaller distance.
  • the anvil instead of a separate counter roll for each forming a region having roll at each rolling station, the anvil also by a table which spans a plane parallel to the axis of rotation of the rollers plane, or be formed by a large counter-roller whose axis of rotation and at least partially their lateral surface parallel to the Rotation axes of the rollers is aligned with the forming areas. Furthermore, the expansion of the one-piece rolling stock can also be achieved by two opposite rollers take place with forming areas whose forming areas face each other.
  • an equal number of bent portions or bends are provided at the corresponding positions on the starting material and the reduction in thickness at the respective sides between two bends or between a bend and the free edge of the Starting material performed. If the deformed profile has a plurality of thickness-reduced sections or regions, then these regions are advantageously formed simultaneously. Alternatively, the thickness reduction of the individual areas takes place successively in several rolling steps.
  • the bending of the starting material and then the deformation of the starting material in the width direction of the starting material is provided before the spreading of the starting material.
  • the starting material is first bent, for example by means of profiling rollers in a mold, the z. B. corresponds substantially to the final shape of the profile to be produced, and then by means of the rollers with the forming areas in the desired portions of the starting material partially reduced in thickness.
  • the bending of the starting material and the transformation of the starting material in the width direction of the starting material take place simultaneously.
  • the at least one bent portion or the bend is formed during the spreading at least at the beginning of the spreading of the starting material, whereby the number of required stations of the rolling mill for the production of the profile is reduced.
  • the bending and forming is thus advantageously at least in the initial phase of a multi-stage cold rolling process.
  • one of the roll with the forming area opposite counter roll is provided with a support portion and at least one support portion which holds the starting material in position during processing and supports the forming of the at least one bend in the starting material.
  • the forming of the starting material in the width direction of the starting material preferably takes place by means of laterally offset forming regions of rolls following one after the other in the feed direction.
  • offset in the transverse direction in the Starting material penetrating forming regions of the rolls is advantageously ensured that the deformation of the starting material takes place only in the width direction in a multi-stage cold rolling process.
  • the spreading of the starting material can take place on the one hand only on one side or on both sides in a direction parallel to the width direction of the starting material.
  • the stock is gradually bent from roll to roll to the profile having the desired shape. This allows a simple production of the profile with a small number of required stations of the rolling mill without the generation of significant stresses in the starting material.
  • the at least one bent section is bent back into a profile in a further method step before the further processing of the formed and bent starting material.
  • the at least one formed before or during the reduction in thickness bend is used in this embodiment of the multi-stage cold rolling process only as an auxiliary bend and is repealed before forming the reduced-thickness starting material to the desired profile.
  • the auxiliary bend allows during the reduction in thickness an advantageous spreading of the starting material and at the same time ensures great flexibility in the design of the cross section in the production of the profile.
  • the forming areas of the rollers penetrate equally deep into the starting material. This results in the width direction, d. H. transverse to the feed direction or to the rolling direction, between the reduced in thickness and the non-reduced in thickness sections of the starting material only homogeneous, oblique thickness transitions, which also have a small extent transverse to the feed direction. Furthermore, the reduced thickness portion of the starting material has a favorable surface quality.
  • FIGS. 1A to 1C is a first embodiment of a cold rolling process for producing a in FIG. 2 shown U-shaped profile 16 of a one-piece rolling stock as the starting material 6 shown schematically in three steps, in which the starting material 6 for the area reduction in thickness serving by forming, laterally offset forming regions 28, 38, 48 of successively following in the feed direction rollers 26, 36, 46 is formed as a thickness reducing rollers in the width direction of the starting material 6.

  • the first counter-roller 22 has a support region 24 extending parallel to its axis of rotation 23 and two mutually-inclined support regions 25 extending at an angle O to the rotation axis 23 on the outside.
  • the first roller 26 with the forming area 28 has, on the outside and spaced from the forming area 28, two profiling areas 29 extending parallel to the supporting areas 25, which are inclined approximately or at the same angle as the supporting areas 25 of the first counter-roller 22.
  • the forming area of the roller extends into its profiling areas. In this case, two in the rolling direction or in the longitudinal direction of the starting material 6 extending bent portions 8 are attached.
  • the thickness reduction of the starting material 6 is formed between these bent portions 8 in an initial stage of the multi-stage cold rolling process. Bends, which form an additional edge spaced apart from the free edge 9 in the starting material 6, thus run between the area 7 to be reduced in thickness and a free edge 9 of the starting material 6.

  • the width B of the forming area 38 of the second roller 36 is greater than the width A of the forming area 28 of the first roller 26, wherein the forming area 38 with respect to a rolling axis of symmetry of the rollers 26 and 36 with respect to the forming area 28 of the first roller 26 widened on both sides.
  • the spreading of the starting material 6 is also effected here by means of the forming region 38 of the roll 36 in the rolling stock plane in the direction of the axis of rotation 37.
  • the second counter-roller 32 has a support region 34 extending parallel to its axis of rotation 33, which in this embodiment has the same width M as the support region 24 of the first counter-roller 22, and on the outside two mutually inclined support regions 35 running at an angle P to the axis of rotation 33 ,
  • the support portions 35 are inclined more than the support portions 25 of the first counter roll 22, so that the angle P is greater than the angle O is.

  • the bent portions 8 of the starting material 6, which at the end ( Fig. 2 ) form the side walls 17 of the U-shaped profile 16, further inclined to the thickness-reduced portion 7 and thus to the bottom portion 18.
