Description

With a hard one reinforcing ring (or several).

This is achieved by the fact that the annular shoulder is made in the form of half-rings mounted on moving carriages movable in the perpendicular axis of the assembly drum, and the assembly drum is made with an annular groove on the outer surface.

The device has a carriage moving along the axis of the assembly drum, on which you can see carriages carrying half-rings of shoulders. To adjust the spacers, the semirings between the ring shoulders are provided with slits and locking bolts and screws installed in them.

FIG. 1 shows the proposed device, front view; in fig. 2 shows section A-A in FIG. one; in fig. 3 shows a section BB in FIG. 2; in fig. 4 shows a section B-B in FIG. 2; in fig. 5 is a section of YYD in FIG. 2; in fig. 6-13 - technological operations of assembling the rubber cord shell on the machine.

The device contains mounted on the frame 1 right 2 and left 3 headstock. On the right headstock 2, a drive shaft 4 is mounted, on which an expanding assembly drum 5 is mounted. On the same headstock, a right edge lifting mechanism 6 and a right side ring landing mechanism 7 are mounted. The release drum 5 consists of segments that move radially (by a predetermined amount ) using the drive device 8 (Fig. 6). On the outer surface of the drum 5 in the middle of its segments there is an annular groove “a with a semicircular cross section. The left grandma 3 has a movable caliper 9, on which the shaft 10 is mounted. On this shaft is a mechanism 11 for lifting the left meek and a mechanism 12 for landing the left side ring.

On the frame I (Fig. 2), the guides 13 are attached, along which the trolley 15 moves along the rollers 14 along the axis of the assembly drum 5 (Fig. 2). On the cart 15 in the supports 16, two schtangovnyh guides 17 are fastened. On the guides 17, carriages 18 and 19 are movably mounted, bearing half rings 20 and 21, which form a removable shoulder of the assembly drum 5.

The carriages 18 and 19 move along the guides 17 perpendicular to the axis of the assembly drum and serve to dilute the semirings 20 and 21 in order to pass them through the ring of the plate or through the sides of the rubber-cord sheath. The half-rings are fixed in the carriages 18 and 19 with screws 22 (Fig. 1). The semirings of c6edin to) tc between themselves in a single ring with the help of cap screws 23 and nuts 24, when they

instituted on the drum 5 when assembling the shell. Each half ring has two shoulders - the right 25 and left 26 (figs. 3 and 4). The shoulders have support surfaces “b” directed radially from the center of the drum 5. The shoulders serve to shape and process the sides of the shell. The cylindrical surfaces in the half-rings are in contact with the rubber cord bracelet at the ends of the assembly drum 5. The shoulders 25 and 26 are connected to each other with bolts 27 (FIG. 4), which fasten the slats 28 on the shoulder 25 to the slats 29 on the shoulder 26. The slats 28 have slots &ggr; that allow; change the distance between the support surfaces of the shoulder of both shoulders, which is necessary when changing the distance between the side rings of the shell depending on the design of the shell. Shoulders are moved apart using screws 30 and nuts 31 (Fig. 3). The half-rings are closed from above by covers 32. In the initial position, the support 9 is retracted to the left and there is a gap between the drum 5 and the edge lifting mechanism 11 for putting the rubber cord bracelet on the drum. 5 or removal from it of the finished shell. The half-rings 20 and 21 are at this time located between the support 9 and the edge lifting mechanism 1I on the carriages 18 and 19 with the fixed bolts 22.

Before operating the device, the bolts 23 are opened so that the carriages 18 and 19 can be moved along the guides 17 in order to move the half rings 20 and 21 away from the center so that they can pass through the mechanisms for fitting the side ring and lifting the edges.

The shells are assembled on the device as follows.

The cord-rubber bracelet 33 is put on the drum 5 (Fig. 6) and then the brass ring 34 is supplied to the bracelet to the ring groove on the assembly drum 5. Then compressed air is supplied to the drive device 8. The segments of the assembly drum are radially diverted from the center of the clamping to the bracelet 33 (Fig. 7), and the reinforcing ring 34 presses the bracelet into the ring groove, thereby fixing the bracelet on the assembly drum. Next, the caliper 9 comes with mechanisms for raising the edge and landing the bead ring to the drum 5, carriages 18 and 19 are moved apart with half rings 20 and 21 from the center and the carriage 15 moves along the drum to coincide with the middle planes of the drum and half rings (Fig. 8). Thereafter, the carriages are moved to the center until the semirings touch. The latter are fastened at the top by folding bolts 23. Then the screws 22 are loosened and the carriages, together with the carriage 15, are retracted to the left headstock 3, and the half rings at the bottom are joined by folding bolts 23 (Fig. 5). Now

The cord bracelet is sandwiched between the cylindrical surfaces in the shoulders 25 and 26 and the cylindrical surface of the drum 5.

Mechanisms 6 and 11 of lifting the edges of the cord are lifted onto the supporting surfaces of the shoulders 25 and 26 (Fig. 10). Mechanisms 7 and 12 of the landing rings are set side rings SJ, and the mechanisms for lifting the edges are removed to its original position (Fig. 11). Then the ends of the cord are folded onto the side rings and rolled up (Fig. 12), and the caliper 9 with the mechanisms 11 and 12 is retracted to its original position. The cart 15 is brought under the drum, the bolts 23 are turned off and the half rings 20 and 21 are secured with bolts 22 on the carriages 18 and 19. Thereafter, these carriages are separated and thus the half rings are retracted from the assembled casing and the cart 16 returns to its original position. The assembly drum is compressed, the rubber-cord sheath 36 is removed from the drum and transferred to the formation and vulcanization (Fig. 13).

The following shells are assembled in the same order.
