Definitions
- the present invention relates, as its statement indicates, to a molten metal feeder for centrifuge machines.
- FIELD OF THE INVENTION This feeder device has been designed for application in semi-automatic single plate centrifuge machines and, also, in automatic machines with three or more plates to collect molten metal from the oven, transfer it to the centrifuge machine and pour it into this, having been designed to occupy the minimum possible space and admit configuration for both side and rear oven.
- the present device is constituted by an automated and programmable assembly comprising an arm that, on one end, is radially fixed on the rotating axis of a motor reducer mounted on the corresponding centrifuge machine and, on the other, is articulated to another arm that hangs vertically from it and that carries a lower saucepan.
- the movement of the arms is carried out by means of the motor-reducer, and the movements, speeds and working sequences of the set are controlled by an electrical panel with PLC and frequency inverter, selecting the functions and variations of working parameters through a panel of controls with touch screen, and identifying the positions of the arms by means of a system of cams and micros or by means of encoder.
- said motor-reducer acts on the articulated arms, they immerse the saucepan in the molten metal of the furnace to collect a certain amount of it and transfer it to the centrifuge machine to pour it into it, the amount of metal to be poured being adjustable and the pouring speed.
- the bucket is attached to the arm that carries it through a U-holder inverted fixed by its intermediate part to said arm and its ends in opposite parts of the mouth of said saucepan, which always descends vertically either to the oven or to the centrifuge machine.
- this saucepan is adapted to the level of metal in the oven by means of a level probe, which can be advantageously constituted by the saucepan itself, being this one made of stainless steel and thus avoiding an element that would be mounted on said saucepan.
- said saucepan has at its bottom a small opening with a shut-off valve actuated by a pneumatic cylinder so that with the programmed operation of said cylinder the valve is opened and closed by letting in or out molten metal
- the automated assembly has, around at least a part of it, a protective screen of a suitable material, which must be transparent or have openings so that the operator can observe the indicated automated assembly and control its operation.
- Figure 1 is a schematic front elevation view of an installation comprising an oven, a centrifuge machine and the feeding device in question.
- Figure 2 partially illustrates, and in perspective, the two arms of the device immersing the saucepan in the oven.
- Figure 3 also shows, in perspective, a part of the carrier arm of the bucket and said bucket with it pouring the molten metal into the centrifuge machine.
- the molten metal feeder device for centrifugal machines illustrated consists of an automated and programmable assembly (1) formed by a motor reducer (2) to whose rotating shaft (3) is fixed radially by one end one arm (4) at whose other end articulates a second arm (5), which is tubular and hangs from the previous one.
- This second arm (5) supports a bucket (6) inferiorly through an inverted U-bracket (7) fixed by its intermediate part to said arm and by its ends in opposite lateral parts of the bucket's mouth (6), the which has at its bottom a small opening (6 ') that is closed with a valve (8) operable by a pneumatic cylinder (9) mounted on the arm (5).
- the assembly (1) is mounted (as illustrated in Figure 1) on the centrifuge machine (MC) so that when said assembly acts by moving the arms (4, 5) towards the oven (H) and towards said machine centrifuge (as indicated by arrow (F) of the indicated figure 1), the bucket (6) can penetrate both the container (C) of said oven and the molding receptacle (R) of the said centrifuge machine, which It includes an electrical control panel (CE) with a frequency inverter to regulate the different speeds of the motor-reducer (2).
- CE electrical control panel
- the centrifuge machine (MC) also includes a programmable automaton (not shown) for the different functions of the feeder, and a control panel (PM) with adjustable support (S) and equipped with a touch screen (PT) for entering the parameters of work and control of the different functions and cycles.
- a programmable automaton for the different functions of the feeder
- a control panel with adjustable support (S) and equipped with a touch screen (PT) for entering the parameters of work and control of the different functions and cycles.
- PT touch screen
- the cycle begins with the positioning of the bucket (6) on the molten metal container (C) of the corresponding furnace (H) and its immersion in said metal (figure 2) to a depth programmed to load the convenient amount thereof through the opening (6 ') of said bucket and after the subsequent opening of the valve (8), clean metal entering when the slags are present only on the surface of the molten metal. Then the valve (8) closes the opening
- the saucepan (6) returns to the furnace (H) and recharges metal, waiting for the relevant signal to start a new cycle. If the set (1) does not receive that signal in the programmed time, and to avoid the cooling of the metal, an alarm signal is triggered and the dipper (6) returns to the oven (H), empties its contents and retracts to a passive position
- a screen (10) in strokes and dots in figure 1 which, removably mounted between the centrifuge machine (MC) and the oven (H), must be transparent or have multiple openings so that the set (1) can be observed by the operator and he can control it properly.
- the screen (10) comprises a door (10 ') for access to the automated assembly (1) for when it is necessary to inspect it or for any other incident, as well as a safety device which prevents or stops the operation of said assembly when the door (10 ') opens.
- This cast metal feeder device can be manufactured for centrifugal machines in any shape and size, with the most appropriate means and materials and with the most convenient accessories, the component elements being able to be replaced by other technically equivalent ones, as all of this is understood within the claims.
