Description

one

The invention relates to the machining of metals, namely, devices for winding or unwinding metal tapes.

A known winder comprising a base with mounted on it with the possibility of translational movement by the bodies carrying drums for setting the roll and clamping cylinders 1.

The disadvantages of this winder are low rigidity due to the cantilever arrangement of the drum, which does not have additional support, and deformation of the inner turns of the wound roll tape when the rolls are from the drum, because when the roll is pushed from the drum, the rubbing turns the tape. This leads to telescoping, bending and twisting of the internal coils.

Also known is a winder comprising a housing (base), a two-segment drum with wedge pairs "segment-shaft, configured to fold-open segments along wedge T-shaped guides, a spline connection designed to synchronize the rotation of the drum heads, hydraulic drives for horizontal movement both drum heads for folding-opening the segments and clamping

the ends of the metal belts, an electromechanical drive for rotating the drum and a puller with rolls 2.

The need to use heterogeneous hydraulic and electromechanical drives significantly complicates the design of the winder due to the introduction of hydraulic stations and hydraulic equipment and reduces its reliability. In addition, when

the work of the winder is inevitable deformation of the inner turns of the roll tape when removing the rolls from the drum, because in the process of breeding heads in different directions the inner turns of the tape are carried away

the account of friction forces after the heads, which leads to the telescoping of the roll tape and its deformation with bends and twisting of the turns. As a result, the quality of the winding is significantly degraded.

rolls whose inner coils are discarded. Such a winder design has limited technological capabilities when switching from a wide coil to a narrow one, since its use for winding a narrow coil after longitudinal cutting is technologically and economically impractical.

The purpose of the invention is to improve the quality of winding and the expansion of technological

winder capabilities.

For this, a double-hinged winder comprising a base with guides, a drum with two drive heads mounted for horizontal movement along the guides, drum-mounted segments, a mechanism for radial displacement of the segments, a mechanism for synchronizing the rotation of the heads and a puller of rolls with stands, fitted with puller racks coaxially with the drum with end discs installed with the possibility of interaction with the drum heads and rollers located on the racks and connected nnym with the end discs, wherein segments are formed with longitudinal grooves and Mechanical wheels made with radial studs, the number and shape of the respective grooves.

FIG. 1 schematically shows the proposed winder; in fig. 2 - view A of FIG. one.

The winder contains two stationary beds 1, in the uprights of which the upper guides 2 are fixed, and the lower guides 4 are attached to the base m 3. The upper guides 2 are mounted with the possibility of horizontal movement of the drum heads 5 and 6 for winding tapes. The master head 5 is equipped with an electromechanical actuator 7 connected with a mechanism for synchronizing the rotation of the heads, which is made in the form of two shafts 8, clamping the ends of the winding tapes, mechanism 9 and for folding and opening the segments 10 with longitudinal grooves 11.

At the end of the shafts 8, there is a driving centering mechanism 12 equipped with a spring 13. On the bases 3, electromechanical actuators 14 are installed, which are connected through gears 15 with driving screws 16, which provide for horizontal movement of heads 5 and 6.

Removers 17 rolls are mounted in lower guides 4, equipped with screw drives 18 and face discs 19 rotatably mounted on rollers 20 mounted on fingers 21 mounted on vertical racks of strippers 17, and discs 19 rest on inner rollers 22. the outer diameter of the discs 19 are in contact with the rollers 23.

On the lower nanowire 4 there are clips 24 for fixing the pullers 17. The end discs are made with pins 25, which are constantly in a fixed state with grooves 11 segments 10.

The stationary beds 1 are equipped with limit switches 26 mounted to move along the beds to control the movement of the heads 5 and 6.

The winder works as follows.

four

The 17-roll pullers are installed in accordance with the width of the winding pslon, and the vertical plane passing through the connected ends of the OIL 8 or the face of the disc 19 from the leading head 5 is taken as the base of reference. In the first case, both the pullers 17 are on the lower guide 4 by means of screw drives, they are moved to the center to the required width. In the second case, one puller 17 from the side of the driving head 5 remains in place, and the other puller is moved to it to the required distance and fixed with the help of clips 24. Then the limit switches 26 regulate the course of horizontal movement of heads 5 and 6 so that types 25 the end discs 19 were constantly located in the slots 11 of the segments 10. When the ends of the shafts 8 of heads 5 and 6 approach each other, the novodo-centering mechanism first contacts its protrusions and sinks into the hole of the shaft 8, compressing the springs 13. Turning one shaft 8 to some Is achieved a position where the protrusion 12 is aligned with the groove mechanism, the shafts 8 and center themselves are connected. Coiler prepared for operation.

The ends of the tapes, coiling into rolls, are inserted into the groove of the drum, after which, using an electromechanical drive, the tapes are clamped and the segments 10 open. With further operation of the drive 7, the tapes are wound into rolls. After the winding is completed by the drive 7, the mechanism 9 is opened and the segments 10 are folded. The inner ends of the tapes of the wound rolls are released, then they turn on both drives 14, which rotate the screws 16 through the gears 15, and the heads 5 and 6 move in different directions along the guides 2.

First, the wound rolls are carried by the drum to the fixed end discs 19, and then as the heads 5 and 6 move apart, the rolls are removed from the drums and fall onto the vehicle below it on the track.

At the same time, the quality of the roll tape does not decrease, since the plugs 25 do not allow telescoping of the inner screws of the rolls: they do not cause deformation, “wipe off the turns of the roll tape from the drum segments, no matter how small they are.

If the total width of the wound rolls does not exceed the distance between the face disk 19 of the driving head 5 and the end of the shaft 8 (at the point of contact of the mechanism 12), the use of the head 6 in the operation of the winder is not practical. The head 6 is moved by the actuator 14 to the non-operating position.

The use of homogeneous electromechanical drives without hydraulic stations and hydro

equipment simplifies the design of the coiler and ensures the reliability of its work. The use of adjustable pullers equipped with spikes to remove coils without deforming the inner turns of the tape improves the quality of the coiled roll tapes. The ability to wind coils, both wide and narrow, without retooling, the winder expands its technological capabilities.
