(5) DEVICE FOR THE MANUFACTURE OF THE HOLLOW

I

The invention relates to equipment for the manufacture of hollow rubber tubular products and can be used in the tire industry, in particular in the manufacture of, for example, pneumatic tires from rubber sheet materials.

A device for the manufacture of hollow tubular products is known, comprising a horizontally mounted rotatably driven drum with a roll roller for forming a retaining junction and a support roller with a roll roller for forming a running joint and mechanisms for pressing the roll rollers 1.

A disadvantage of this device is that the formation of the running joint and its subsequent rolling in sections, with the vertical arrangement of the workpiece disks, leads to the formation of a transverse crease at the end of the running crfe or unacceptable TUBE PRODUCTS

my stretch the edges of the workpiece, which leads to lower quality products.

The aim of the invention is to improve the quality of products by eliminating the stretching of the edges of the blanks of the latter.

The goal is achieved by the fact that a device containing a horizontally mounted with a rotatable drive from a drum with a press roller for forming a retaining junction and a supporting roller with a roller for forming a running junction and mechanisms

ts press down press rolls, equipped with a horizontally positioned table for placing workpieces, installed with the possibility of free rotation relative to

X vertical axis, and the drum and support roller mounted & on the side of the table, with the top forming a cylindrical side

The surfaces of the support roller are located flush with the working surface of the table.

Figure 1 shows the described device; figure 2 is a view of And figure 1; fig.Z - the drum at the time of the stitching of the retaining joint; figure 4 - supporting roller at the time of rolling the running of the joint.

A device for manufacturing hollow tubular products comprises a bed 1, on which a mounted table 2 is arranged for placing a workpiece blank. For stitching the retaining junction on frame 1, on the side of table 2, there is mounted an isotonic drum 3 with a press roller mounted on an L-shaped bracket 5, mechanism 6 presses roller i and pressure regulator 7, and for stitching the running joint on frame 1 from the opposite The sides of table 2 relative to beraban 3 are mounted horizontally positioned supporting roller 8 with press roller 9, mechanism 10, press roller 9 and pressure regulator 11. The upper forming cylindrical side surface of the supporting roller 8 is flush with the working surface of the table 2. The drum 3 and the supporting roller 8 are connected, for example, via chain drives (not shown) to the drive 12 for their rotation mounted on the base 1.

The latter also includes a control panel 13 and pedals I and 15, respectively, for starting the drum 3 and the support roller 8 and for pressing the press rollers i and 9. The table 2 is mounted for free rotation about the vertical axis 16.

The device works as follows.

The billet 17 of the product, such as a camera, is placed on the table 2 devices and manually form a retaining junction 18 according to the existing technology. Then, the blanks, interconnected by the banding junction, are transferred to the drum 3 (see FIG. 3). Pressing the pedal 15 includes an electromagnetic clutch (not shown), transmitting the rotation from the actuator 12 to the drum 3. The drum 3 begins to rotate, dragging the workpieces 17, which are pressed onto it by the press roller 4, and the retaining junction 18 is thus rolled up. Roller preload force k

is regulated by a pressure regulator 7 by changing the pressure in the pneumatic cylinder of mechanism 6 in the range from 0 to A500 And at a pressure supplied with compressed air of 6 kgf / cm.

5 Then, the workpieces 17, connected and rolled over the retaining junction 18, are removed from the drum 3 and placed on the table 2, where a valve is installed on the workpiece (not shown in the drawings) and rolled, and then the workpiece is joined along the running joint 19 and shifted joint 19 on supporting roller 8 (see fig.). The roller 5 is made at 5 by turning on the Il pedal the electromagnetic clutch (not shown in the drawings), transmitting the rotation from the actuator 12 to the supporting roller 8, simultaneously

0 applying pressure to the pneumatic cylinder (roller 10 is not shown on roller 9). When stitching the running junction 19, the junction of the camera lying on the freely rotating table 2 should be directed under roller 9. ranging from o to

p 500 And by adjusting the pressure regulator 11.

Laying the workpiece on a horizontal free-rotating table when sticking a running joint ensures uniform distribution of material along the edges of the workpieces.

The implementation of the invention eliminates the formation of a transverse fold or stretching of the edge of the workpiece when stitching the running joint of the chambers, which will significantly improve the quality of the manufactured products.
