    Winding device for metal strips, in which the metal strip is braked between two rollers which are pressed against one another. One of the rollers has a larger angle of wrap for the metal strip of at least 75 DEG and the other roller has a smaller angle of wrap for the metal strip of 45 DEG at maximum. The one roller with the larger wrap includes material on its periphery having a coefficient of friction for the material which is at least 20% lower relative to the braked metal strip than the coefficient of friction of the peripheral material of the other roller with the smaller amount of wrap.

    (54) WRINKER FOR METAL TAPE WINDING
    one
    The invention relates to the field of metal forming and, in particular, can be used in installations for winding several tapes.
    A device for winding metal tapes is known, comprising a base, a drum mounted on the base and two rollers 1 arranged in front of the drum one behind the other.
    The disadvantage of this device is that in order to evenly wind the strips, tension is required during winding, which is created by an additional mechanism, which results in damage to the strip surface.
    Also known winder for winding metal tapes, containing. base mounted on the base of the drum, two pressure rollers located in front of the drum, and a brake device t2
    This coiler also does not solve the problem of protecting the strip from damage due to its contact with the clamping mechanism.
    The purpose of the invention is to improve the quality of winding by ensuring uniform tension.
    This goal is achieved by the fact that each roller is made with a coating, the coefficient of friction for the first roller is 20% less than the coefficient of friction of the coating for the second roller.
    The winder rollers are installed with the ability to interact on the generators.
    0
    The brake device is installed with the possibility of interaction with the second .. roller.
    The rollers are set at a distance from the drum generator equal to half the diameter of the first roller.
    On the basis of the pivotally mounted balancer, and the pressure rollers are located on the balancer.

    Figure 1 shows a reel layout; figure 2 is a top view of figure 1; on fig.Z - a variant of the scheme in figure 1; figure 4 - the design of the circuit in figure 3; in Fig. 5 and b, the variations of the circuit in Fig. 1.
    The winder for winding metal strips contains a base 1 mounted on the base of the drum 2 and two pressure rollers 3 and 4, between
    0 which pass the strip 5. The circumference of the roller 3 is a little less than 15, and the circumference of the roller 4 is like 120. The roller 3 is pressed against the role 4. The distance between the pressing point E to the point of incidence R is about 4/9 of the roller circumference 4. The bags first arrive at the separating roller installed in front of the rollers 3 and 4 6. When the angle of the roller's circumference is 4 120 °, which corresponds to 1/3 of the circumference, for the free length of the path of the cut strips between the points and E there remains only a section of approximately 1/9 of the circumference of the roller 4. Roller 3 (FIG. 3) is located vertically under ro. 4 .pomoschyu priimnogo pressed with means 7 to the roller 4. The roller 3 is connected to a brake device (not shown). The girth of the roller 3 (see fig. 3) is limited practically by the size of the contact area of the coating material of the roller 3 on separate strips. In this case, the circumference angle (b is almost zero. Depending on the surface material and the clamping force, the contact area between roller 3 and individual strips is obtained, which corresponds to the angle of circumference fJ from 1 to 4 °.
    Additionally, provision can be made for providing mobility of the base 1 with respect to the winding drum (see Fig. 4). To this end, the base 1 is located on the guides 8. The relative mobility of the clamping device relative to the winding drum provides a distance between points R and A (Fig. 1) between roller 4 and the metallic tape wound on the drum less than 100 mm. With the growing volume of metal tape on the winding drum 2, the winder moves continuously to the right. When winding a dry metal tape, plastic-fiber material with a friction coefficient of jU 0.28 is provided as a coating material for roller 4 with a large girth angle, while polyurethane with a coefficient of friction of ju 0 is used as the surface material of the less-wound roller 3. five.
    4, it is provided that both rollers 3,4 are located. on a common rocker 9, which can rotate around a central
    middle axis 10 at ISO, so that roller 4 can take the position of roller 3 and vice versa. This is used when changing, when winding dry metal
    Tape. On the oiled metal tape, when it is necessary to take into account the change in the coefficients of friction with respect to the material of the coating of the rollers 3,4.
    Figures 5 and 6 show embodiments in which both rollers are mounted on the oscillating balance.
    11, which at one end is mounted on axis 12. By increasing the winding diameter, the rocker balance bar 11 rotates to the right around axis 12. For this purpose, for example, there is a piston device 13 (FIG. B). In: jc.i balance bar 11 with axis 12 is located
    so that the angle of grasp of the OS at roller 4 is as small as possible. For the roller with the greatest girth, the angle of girth is 90 to 150 ° C. Leather, α-polyurethane and synthetic fibrous material are used as the coating material for rollers 3 and 4. The choice of material is based on the coefficient of friction, and it should be borne in mind that dry metal tape or oiled metal tape is inhibited.
    The operation of the winder is carried out as follows.
    The pressed roller 3, which is predominantly inhibited, performs mainly a braking function on individual lanes 5. There is no side sweep of individual lanes during the braking process, since with a large wrap angle another roller is provided with reliable direction with good slippage. Good
    and slippage contributes, along with a large girth, also insignificant coefficient of friction of this roller, while slippage
    - does not damage the surface of the strip.
    The coiler provides uniform braking in a good direction and eliminates damages to the surface of the strip, and the best results are obtained if the distance between the points A and R is kept to match.
