Definitions
- the object of the invention is to provide a Rotationsgussstrom, which overcomes the disadvantages of the prior art and compared to the prior art works more energy efficient. It should offer the possibility of a quick and cost-effective assortment change of the products to be produced for the series but also a cost-effective way for the production of
- This type of device makes it possible to set tool shapes with minimal technical effort in rotation. Consisting of at least one Nagaufhahme, with the outer contour of a ball and a holding device in which this ball is rotated by only one drive element in rotation.
- the holding device for the spherical Aufhahmevorraum for receiving the Gußnegativformen of at least three approximately vertically formed support and guide elements in the form of tripods is formed, which are in contact with the ball via guide pads.
- the guide supports the rotation of the ball is supported, in which they are formed, for example, as all-round movable roller bearings.
- the drive unit is designed as a motor-driven horizontally arranged turntable, on which the drive element in the form of a separate means of another motor
- Guide tripods and / or the guide pads of the support and guide tripods formed variable position and can thus be adjusted to the required position.
- the holding device for receiving the Aufhahmevoroplasty is designed as a cup-shaped holding device and the drive element as a pressure-controlled separation and
- the separation and guide medium is formed.
- the separation and guide medium is advantageously by means of at least one control nozzle in the space between the shell surface and the surface of the spherical
- Shell surface of the holding device and the curvature line of the ball are formed equivalent.
- separation and guide medium liquid or gaseous medium of suitable consistency and layer thickness are used.
- the control nozzle is controllable so that the direction of change of the ball rotation and the rotational speed are controlled.
- the individual casting negative molds are each in the region of the parting plane in one, in the spherical Aufhahmevorraum
- Receiving device segments may be arranged so that cost-effective and time-saving can be converted to a new range.
- Fig. 4 is a schematic representation of a changeover insert 3 for the
- Embodiment 1 Inclusion of at least one casting negative mold and casting material. Embodiment 1
- the receiving device 1 is designed as a ball for receiving at least one cast negative mold 4.
- the holding device for the spherical Aufhahmevoriques 1 consists of three approximately vertically formed tripods, which serve as support and guide elements 5.
- a guide pad 6 are arranged in the upper region, which are advantageously designed as all sides movable roller bearings. With these guide pads 6, the tripods with the ball in contact and thus lead and support the position and the rotational movement of the ball.
- the drive element 9 which consists of a force-transmitting contact with the ball drive wheel and a turntable 7, the ball is driven in its rotational movement.
- the turntable 7, which is arranged horizontally in the rotary device, has a separate motor 8 and can therefore be controlled separately and in a clock-like manner.
- the drive wheel also has a separate motor 8 and is also controlled by this separately. Since the drive wheel perpendicular to the rotation device on the
- the support and guide tripods to ensure the position positioning and resizing to different sizes
- Magnetic lock system is formed, the ball during the
- the filling and molding compound 10 is arranged in each case, in which a receiving area for the arrangement of the casting negative mold 4 or of a replacement insert 3 according to FIG. 4 is formed.
- the cast negative mold 4 can be arranged with the casting material directly in the filling and molding compound 10 or in a removable insert, the cast negative molds and the casting material are added.
- the individual cast negative molds 4 are each arranged separately in the region of the parting plane 2 in the filling and molding compound 10, at least on one side and by at least one parting plane 2 also in their shape.
- the cast negative mold or the interchangeable insert can be incorporated in the manufacture of the Aufhahmevorraum 1 of filling and molding with the same and positioned or it can be subsequently worked out by a sintering process, the Gussnegativform, poured the casting material and the ball are closed.
- this Aufiiahmevorraum must be destroyed to remove the finished moldings.
- the ball can be opened either on the guide tripods and re-equipped with interchangeable inserts 3 or the negative molds 4 with casting material.
- Receiving device of the holding device can be assigned.
- Embodiment 2 is a diagrammatic representation of Embodiment 1:
- Holding device for receiving the spherical Aufhahmevorraum 1 is designed as a cup-shaped holding device 12 and its Schalenbogen- diameter corresponds approximately to the spherical surface curvature. Between the shell surface and the surface of the spherical
- Traumhahmevoriques is a separation and guide medium 13 arranged by means of a controllable control nozzle 14.
- the separation and guide medium 13 and the control nozzle 14 serve as a drive element 9 for initiating the ball rotation.
- the control nozzle With the control nozzle, the direction of rotation change and the rotational speed of the ball are regulated.
- liquid and / or gaseous media of suitable consistency and layer thickness are used, such as water, oil, air and other media.
- the receiving device 1 may be formed as in the embodiment 1 and be used for the device in its different variants are used.
- the positioning of the ball during rotation can be monitored and adjusted for the opening of the ball.
- Direction of rotation change of the ball and its speed can be controlled.
- the adaptation to different requirements of the rotary casting process can be set and regulated quickly and easily via the control nozzle.
- the removal and reassembly can also be done here during the stay of the ball in the fixture or after removing the ball from the fixture.
