SU1636249A1 - Compensator of bead-making machine - Google Patents

Abstract

The invention relates to equipment of the tire industry and is intended for the manufacture of tire parts, in particular bead rings. The purpose of the invention is to improve the operating conditions of the compensator. For this, the carriage (K) is mounted on guide racks by means of tapered grooves for mounting racks therein. The bushings are mounted on eccentric axles. It is equipped with supports with horizontal grooves. The rollers K are mounted on an axis installed in the slots with the possibility of adjusting the position of the supports. The compensator allows adjustment of the position of the movable K relative to the uprights. Adjusting the position of the axis with the rollers in K will make it possible to install a rubber band in the middle of the rollers so that it does not touch the rollers of the flanges during operation. This will prevent rubber breakdowns from the ends of the rubber band and improve the quality of the manufactured side rings. 6 Il. cl

Description

The invention relates to equipment of the tire industry and is intended for the manufacture of tire parts, in particular bead rings.

The purpose of the invention is to improve the operating conditions of the compensator.

1 shows a compensator, a general view; figure 2 is a fixed block of rollers; on fig.Z - movable carriage with rollers; figure 4 - section aa on fig.Z; figure 5 - section bB in fig.Z; on fig.b - view In fig.Z.

The compensator contains a base 1, on which two round guide pillars 2 are mounted, traverses 3 fixed on guide pillars 2, the upper fixed block 4 having an axis 5 with rollers 6 (figure 2), a movable carriage 7 consisting of two frames 8 and mounted on guide posts 2. Between the frames there are two supports 9, which are fastened to the frames with nuts 10. The supports have horizontal grooves 11, in which axis 13 with rollers 14 can be moved using adjusting screws 12. Rollers 14 by means of bushings 15 mounted on axis 13 with help There are 16 keys. Bearings 17 are mounted on sleeves 15, on which rollers 14 rotate. Movable carriage 7 can be moved in guide posts 2 using four sleeves 18 mounted on bearings 19. All sleeves have tapered grooves 20, which include round guide posts 2.

The axles 21, on which the bushings 18 are mounted, are eccentric and fastened within 8 by nuts 22 (Fig. B). To adjust the weight of the movable carriage, in order to obtain the necessary tension of the rubber band 23, weights 24 are secured to the bottom. The base 1 has a shock absorber 25 that prevents the movable carriage 7 from being damaged in the event that it falls down when the rubber band 23 is broken. two limit switches: the upper one - 26 turns off the electric motor of the winding machine (not shown), the lower one - 27 turns off the electric motor of the pulling machine (not shown). The disconnection is made by the lever 23 mounted on the movable carriage 7.

The compensator works as follows.

During operation of the machine, the rubber band 23 fills the compensator, bending the rollers of the movable carriage 7 and the rollers 6 of the fixed block 4, or is selected from it. In this case, the movable carriage 7 is pushed down or raised up by means of sleeves 18, in contact with conical grooves 20 with round guide posts 2. To adjust the gap between cone grooves 20 sleeves 18 and guide racks 2 sleeves 18 are mounted on eccentric axes 21, the axis of the support ends, by means of which the axis 21 is mounted within frame 8, is offset by a certain amount relative to the axial axis, around which the sleeve 18 rotates in bearings 19. By turning the axis 21 of sleeve 18 within frame 8, it is possible to increase or decrease the gap between the cone 20 of flowing Coy sleeve 18 and the guide rack 2 and thus eliminate inaccuracies of manufacture and gaps which may occur when the wear of these parts.

The rollers 14 of the carriage 7 are mounted on the axis 13 previously at a certain angle to the axial line of the movable carriage 7 (FIG. 4) so that the rubber band 23 bends around the first right roller of the movable carriage 7 during upward movement

On the second right roller of the stationary block 4. Precise installation of the axis 13 by the rollers 14 in the grooves 11 of both supports 9 is achieved by adjusting its position with the help of adjusting screws 12.

In operation, as the movable carriage 7 is moved, the rollers 14 simultaneously rotate in it, as the rubber wire 23 continuously goes over them onto a winding machine template on which the bead ring is wound.

This tape should always be in the middle of the rollers and not touch their flanges, since rubbing the rubber band on the flange of the rollers will lead to a breakdown of the rubber casing and exposure of the wire, which is unacceptable. Thus, adjusting the position of the entire carriage between the uprights 2 and further adjusting the axis 13c with the rollers 14 in the carriage itself allows, during operation, to maintain the position of the rubber band 23 in the center of the rollers The slider carriage 7 and the fixed block 4. Then the cycle repeats.
