description

The principle of the tilt molding machine has been known for years. The tilt mold machine makes a mold with a Vibrators arranged thereon, while brackets arranged on the mold allow the mold to be tilted. Such Arrangements are known in the simplest type of execution, while other arrangements of this type in machine frames built-in, allow an automatic tilting option. The automatic tilting option is for those in the machine frame built-in tilting forms guaranteed by the forward movement of the machine. On the other hand, additional Tilting devices carried out constructively by motor drive via chains or gear wheels, or segment devices being. The automatic tilting of this tilting form is only guaranteed without exception if a complete. Machine frame, which the necessary equipment for the forward drive, or the necessary equipment for the rotation of the mold are structurally arranged on the machine frame «

W hen Kip n euheitlich executed and hereby notified p- Vorrich tung ha ndelt e s to machine drive by a Mashi, which can at each en no rmalen Kippform- Masc h ine HS ebracht shipped.

So that the function of a normal Kippform machine is again sufficiently known, on sheet I in Figures 1 to 5 the simple execution of a free ar work - ^ - den_ Kippform machine, so such a Kippform machine, which is not in is built into a special machine frame.

In the picture 1 u · 2 the two tilt bars are on the left and on the right side of the machine designated as Bl and Br. "The two brackets are with the struts a, b u" c connected, while in a cross strut d the form Fo with dsm arranged vibrator R is suspended »on the left A lever H is arranged under bracket B1. The machine can be tilted by 180 ° by lifting the lever H. In the picture the machine is in the position in which the filling compound

(Concrete) is poured into the mold, and is compacted by the work of the vibrator R. In picture 2 the machine is shown turned by 180 ° and can be demolded in this position. For this purpose a lifting device is attached to the brackets of the machine. This lifting device is not shown in the pictures because the pictures would easily lose their clarity. In order to subsequently describe the principle of the tilting device (turning device), the tilting process of the tilting machine is shown again in Figures 3, 4 and 5 · In Figure 3 it can be seen that over the radius r 1 the tilting movement can be effected by the lever H (Figure 1 u _e 2) * After 9o ° tilt is the machine according to the image 4, and has now a tendency, r in the Pfeilricntung 2 weiterzukippen because the u in Figures 3 »4. 5, The center of gravity S shown now pulls the machine further automatically, so that it must be held in the direction of arrow r 3 by counter-pressure from the operator in order to move slowly or without falling into the position shown in Figure 5. This position is the demoulding position shown in Figure 2 * After demoulding, the machine must be tilted back into the filling position. This is done by lifting the lever H in the direction of arrow r 4.

In the pictures 6 to 11 automatic tilting devices (turning devices) are shown, as they are on the one described above Machine picture 1 u, 2 can be used. Attention should also be drawn to the fact that the stirrup structures for tilt-forming machines as described above, in usually do not represent precise radius designs. As a rule, this is how the stirrup designs are in the filling positions Equipped with rubber feet, which prevents the machine from tipping over a rubber buffer edge in the tangent of the bow radius takes place. If desired, uneven paths or cam designs can be inserted in the bracket construction so that e.g. in the position picture 4, despite the center of gravity to the left, a "stop" for the The machine is tilted

Gear types can be found in all versions according to Fig. 6 u, 11 Use, which are self-locking due to their construction. According to Figure 6, the motor M pushes always only forward at the same pace as the one at which

the engine's gearbox is running. Even in the case when, after a tilting movement of 90 °, the gravitational force of the tilting shape also act.

In the image 6 is an easy to be arranged driving device is shown, which is executed in the journal A attacking expedient four wheels, so that the stub roll device both sides of the machine, ie on the left arm Bl and right bracket Br (Figure 1 u _o 2) is performed. The tilting devices 7 and 8 represent a tilting device which can be constructed using lifting rods. Figure 9 shows a combined driving pressure and lifting pressure device. In this device, the wheel pairs of rolls, each with the same F _a hrdruck on the floor and push the machine in tilt function. In the picture Io and 11 further tilting devices are shown, as they can be carried out by a rotating gear engaging via a chain on the sprocket Kr and Kr 1.

Bs is usually appropriate, the lifting devices weight To be carried out as easily as possible, so that the parts of the tilting device when removing the formwork from the machine create the least possible load for the lifting torque of the machine. Depending on the type of use one Kippform machine can use one of the tilting devices on the left side of the machine or on the right side of the machine. If necessary, it is also possible to tilt both sides with a tilting device to execute.
