Definitions

  • the invention relates to a method according to the preamble of claim 1.
  • the invention further relates to a device for carrying out such a method.
  • the invention relates to the metal working technique and can be used in the manufacture of various products by a rolling process.
  • This method and apparatus are suitable for the production of long products, such as knife edges, by a single downturn.
  • the rollers are rotated downwardly by the rotary levers whose hinge axes of rotation are parallel to the longitudinal direction of the blank plate, which corresponds to the longitudinal direction of the product to be produced.
  • the roll forming surfaces are designed so that products of different thickness - the length of their transverse direction after - but with the same thickness - can reproduce the length of their longitudinal direction.
  • This technical solution can reduce the elapsed time of cold rolling of products thanks to the Laengsverformung of those by rolling, while the plastic metal flow of the blank in the circular direction from our plate edge to the upper edge of the plate is due, therefore, an incomplete shaping of cutting through the Dikkenstreuung the blank plate is caused excluded.
  • problems associated with the shape change of the product after its plastic deformation arise.
  • the shape of the product with simultaneous action by the profiled Walzenformungsflaeche on the blank plate in particular on its zones of greater deformation, where the thickness of the product to be produced is to be smaller, and on the same with smaller deformation, where the thickness of the product to be made larger, is distorted, characterized mainly by bends in the longitudinal direction of blank.
  • the plate in the manufacture of products of complicated configuration by this process, either in the technological processing stage, the plate must be preliminarily prepared by changing its thickness prior to the rolling process, or subsequently process its surface after the product has been manufactured, as a result of which the cost of metal is increased, and Labor costs of the production of the product is increased.
  • the invention is based on the technical problem of specifying a method and a device for producing metal articles from substantially cuboid metal blanks, which make it possible to produce complex-shaped metal articles in a single processing step in a simple manner.
  • the problem to be solved by the invention is, in particular, to provide such a cooling or cold rolling method and the device for its realization, which enable the production of products with complicated configurations, thicknesses which vary in the transverse and Laengsraumen.

  • Variable course of the depth in the direction parallel to a roll axis in a partial area means that the course is not necessarily variable over the entire width (orthogonal to the roll axis).
  • the depth is the distance between two major surfaces of the recess.
  • the negative mold can be set up exclusively in a roller. Then the other roller has no shaping surface structure.
  • the negative mold can also be divided into two recesses, which are then each set up in a roller and facing each other. It is understood that the kinematics of the rolling is then controlled so that the two recesses are as it were reassembled in the course of rolling so that a metal object is obtained with the outer shape of the negative mold.
  • the profile of the depth of the recess in the direction parallel to a roll axis is decreasing, preferably monotonically decreasing.
  • the course of the depth in the rolling direction of the rolls is decreasing, preferably monotonically decreasing.
  • the arrangement is such that in the initial position of the roll surfaces and when positioning of the metal blank defined gaps in height of the maximum depth in the rolling direction are respectively arranged between major surfaces of the recess and main surfaces of the metal blank.
  • the technical result or advantage obtained in the implementation of this method is labor reduction in the manufacture of products with complicated configurations as well as their quality enhancement.
  • the technical result or advantage obtained in the design of the device is an extension of its functional possibilities and its arsenal of technical means for the production of products with complicated configurations, due to the provisional roller suit and the continuous compression of the blank by Rolling zones of maximum deformation of the blank to the zones of its minimal deformation is achieved.

  • the stated object has been achieved by creating a gap between the broad surfaces of the blank plate and the Walzenformungsflaechen before the compression of the plate and the Walzenformungsflaechen has performed in such a way that the blank plate from the zones of their greater deformation to the zones of their smaller deformation continuously has been deformed.
  • the method (Figs. 1, 2) consists in the production of a blank plate 1 (shown in dotted lines in Fig. 1) from a plate of constant thickness and opposite widths and faces 3. On Fig. 1 also, the product 4 (Fig. 3) of varying thicknesses to be produced by the notified process is shown by a continuous line.
  • the axis X is a longitudinal direction of the blank 1 and the product 4 and the axis Y is the transverse direction thereof.
  • the blank 1 can be produced by any method: by shearing the plate after the plate blank, punching u.s.w.
  • the blank 1 is fed between the rollers 5 ( Figures 4, 5, 6).
  • the wide surfaces 2 of the blank plate 1 are directed towards the rollers 5.
  • the long Laengsachse the blank plate 1 should be parallel to the axes of rotation of the rollers 5 (joint axes) in accordance with their Laengsraum.
  • the molding bottles 6 of the rollers 5 correspond to the different thicknesses of the product 4 - the length of its transverse direction (to the side the edge of the knife tip Fig. 1). For the movement of the rollers 5 one uses the lever 7.

  • the value is required for the free arrangement of the blank plate 1 between the Formungsflaechen 6 of the rollers 5 and is about 0.1 ... 0.5 mm, depending on the thickness of the blank plate 1. The thicker the blank plate 1 and larger tolerance tolerance ranges are, the bigger it is.
  • a minimum (FIG. 6) distance 1 must be selected between the shaping surfaces 6 of the rollers 5, in that the gap should be such that the blank plate 1 can be supplied freely between the Formungsflaechen 6.

It is achieved by an appropriate profiling both in the transverse and Laengsrichzung the Formungsflaechen 6 of the rollers 5 -before attaching the rollers to the rotary levers 7.

After the trials it turned out that the value P is chosen based on the true stress values as well as the deformation area of the blank 1. The higher the yield strength of the material and the greater the deformation surface of the blank, the higher the value of the compressive force P of the preliminary roller pressing should be. Usually this value is in the interval from 20% to 38% of the maximum pressure force to be absorbed by the system (rollers 5, lever 7, base plate) during the deformation of the blank 1.
