Description

The invention relates to equipment for the manufacture of rubber technical products and is intended for their manufacture by the method of pressing.

The purpose of the invention is to increase plant productivity.

In figure 1, the image describes the installation; Fig. 2, view A in Fig. 1, of Fig. 3 and 1, installation with a power unit in various operating positions; figure 5 - section bb in figure 1 figure 6 - section bb ng fig.Z.

The plant for the manufacture of molded rubber products contains a rotary vulcanization press 1, which has an annular tunnel chamber 2, an annular body 3 and an installed power shell concentrically with it, heaters 5, a mold b and radially wedge-shaped holders 7 for molds. The power holder is mounted on the frame 9 by means of the support 10 rolling. The holders are mounted in the annular tunnel chamber 2 with respect to their walls and have guides 11 for molds 6. The apparatus has a device for periodically rotating the press 1, which contains a rotary power element 13 mounted on the frame 9 by means of an axis 12 and Oids dyuhksdoaya power cylinder 1). The power body 13 is made in the form of pairs of levers 15 and 16 mounted with one end on the axis 12

on both sides of the vulcanization press 1.

The rod 17 of the power cylinder I is pivotally connected to the frame 9, and the rod 18 is pivotally connected to the free ends of the nearest arms 15 and 16 to it.

The installation has means for exerting pressing force on the molds, which is made in the form of an additional power cylinder 19 and a wedge liner 20. An additional power cylinder 19 is placed between the free ends of the levers 15 and 16 and is hinged to them by the body and the stem. The liner 20 is mounted in an annular tunnel chamber 2 capable of moving in a direction parallel to the axis of rotation of the press 1 and is equipped with a reciprocating actuator in the form of a cylinder 21. The holders are made with cylindrical projections 22 for engagement with the slots 23 of the arms 15 and 16 of the power member 13.

Cylinder 2 is provided to move the levers 15 and 16 relative to each other.

In the apparatus, there are a device 25 for recharging the molds 6 and a device 26 for loading and unloading molds from a vulcanization press 1 onto the device 25. Ll holding the holders 7 with the molds 6 in the reloading zone is designed to fix the tor 27.

I

The installation works as follows.

31

The mold 6 with the workpiece from the reloading device 25 is fed by the device 26 into the guides 11 of the holder 7. After that, the cylinder 21 of the tunnel chamber 2 introduces a wedge liner 20, which creates a pressing force. Then the cylinder 2 moves apart the levers 15 and 16 (Fig. 6), releasing the holders 7, and turning the cylinder 18 And of And turning from one pair of holders to another (Fig. 3). After that, the levers 15 and 16 are shifted by the cylinder 2 and cylindrical projections 22 of the holders 7 are driven into their slots 23. The cylinder 19 is turned on and the pressing force is transmitted to the mold 6. Then the pressing force is removed from the wedge liner 20 and it is removed from the cylinder 21 - recovery press 1. The rods 17 and 18 of the cylinder AND are retracted and the vulcanization press 1 is rotated on the rolling support 10 by two steps (Fig. 1). In this case, the next holder 7 is brought to the zone of the device 25 for recharging and is fixed in this area with the help of the lock 27.

The rod 18 is again moved out of the cylinder And and turns the vulcanization press 1 one step back (Figure 1), freeing the area of the device 25 for recharging, to replace the mold press 6.

The cycles are then repeated as described above. Each mold 6 entering from the device 25 into the vulcanization press 1, under constant pressing force passes (counterclockwise) the entire annular tunnel chamber 2 in returning to the device 25 for recharging.

During the movement of the mold in the tunnel chamber 2, the product is vulcanized.

The described installation provides an increase in the removal of products from a unit of production area and high quality products.
