SU56059A1 - Eccentric Press for Two-sided Horizontal Brick Compression - Google Patents

Description

 Circular on the upper part of the lower frame are molding boxes 4 U-shaped. The bottom of the mold box is an ejector 5, which sits on the rod 6, provided in its lower part with a support roller 7 and reverse rollers, step 8. The rod sits in the guide sleeve 9.

The face parts of the forming box are the 10 and L stamps. (From above, the forming boxes are automatically closed during the pressing with gate valves / 2 with their own slide in the grooves of the forming box. Periodical movement of the valves, through the b g 13, seated in guide sleeves 74 The rods are provided with rollers 15 which are inserted into the groove of the slide J6, which is seated on a vertical rotary shaft 17.

The ejection of a brick from a tin box is made by a pusher that rises and lowers, rolling along rails 18 and 19 mounted on the rim of the pinion 20, which sits on the central vertical shaft of the press.

From below, the brushes are supported by rollers mounted on pillars 21. The gear 20 is driven to rotate from another spur gear 22 mounted on an intermediate vertical shaft 23 mounted in bearings 24 of the gearbox 25. The intermediate shaft is driven by a pair of concentric brushes 26 and 27 from the drive shaft. horizontal shaft 28, placed in the bearing 29 and provided with idle and working pulleys.

On the central vertical shaft are mounted two eccentric cuffs 30 and 31, equipped with holders 32, as well as a reversing slide 55.

The stamp 10 receives a translational movement from the shaft 34 seated in the guide 55. The rod at its other end is provided with a roller 36. When the eccentric cam 30 rotates, through the ferrule 32 the movement is transmitted to the die, and the rotation turns the rotational movement of the cam into translational, which eliminates effort

When the cam 31 rotates, the rod 57, which is seated in the guide 5S and provided with a roller 39, also moves forward by means of the sleeve 32a. At the end of the rod, there is a piston 40 seated in cylinder 41; on the other hand, a piston 42 is inserted into the cylinder, which slides on the rod 43 located in the guide 44. The rod 43 is connected to a two-arm rocker - a lever 45 that transmits movement to the rod 46 in the guide 47. The rod 46 at the other end has a stamp 11 .

In the cylinder 41, water is poured between the pistons, transmitting the translational motion from one piston to another to it when pressed. The water in the cylinder also serves to regulate pressure, being piped to a pressure regulating chamber having direct and reverse valves that can be adjusted to any pressure.

When over-pressurized, the pressure control valve opens and water flows into the main line into a special tank, thereby giving a free stroke to the pistons; during the return stroke, the water is sucked in through the check valve. The pressure in the chamber is recorded by a pressure gauge.

Pistons 40 and 42 are interconnected by a tight 51 so that when the movement is reverse, the tons of tons of tons move zero and forward when moving forward. The piston 42 with the rod 43 is retracted by the backstage 55 through the roller 50a, as well as the stamp 10.

At the end of the extrusion, the dies are consumed. The valve 12 opens the mold and the brick is pushed up by the ejector 5.

The removal of the ejected brick from the surface of the table, as well as the filling of material into molds, is performed by the following mechanism.

At the upper end of the central shaft of the press, a trunk 51 is fastened, which rotates together with the shaft. In the back (along the rotation) part of the trunk, there is a vertical roller, at the lower end of which a loading top 50 is fixed. A gear gear 51a is mounted on the top shaft, which is in engagement with the ring gear 53, mounted on the upper box of the bed. Thus, during rotation, the trunk rotates and the top that loads the forms. At the upper end of the top roller, an asterisk 54 sits, connected by a chain with an asterisk 55, which sits at the upper end of the other roller. At the lower end of this roller sits a pusher with a special configuration. When the trunk moves around the center of the press and the collider around its axis, the brick collides when moving along the cycloid onto an inclined roller table 56.

In the top, the mass is loaded along a chute sleeve 57 extending from the hopper 58, which is fixed on the upper end of the central shaft of the press.

From the inclined roller table 56, the brick comes down to the ring conveyor 59, driven through the crown 60 and gear 61. The brick is removed from the conveyor with a roller puller 62.

The dies 10 and // are provided with electric heating elements mounted to prevent the mass from sticking to the chips.

To suck air from the molds (during the pressing period), a vacuum unit is installed, connected to the press molds through a manifold 63 and flexible hoses attached to the dies 10 Vi 11.

The adjustment of the mold filling is done by drawing together or expanding the dies 10 and // by raising or lowering the backstage 33, which has the inclined surfaces of its grooves. The flywheel 64 is raised and lowered by the worm 65.

The subject matter of the invention.
