Maneuvering arrangement for casting installations

专利摘要:
In an automatic foundry plant where automatic core feeding and exchange of core masks (48) as well as pattern plates are required, both a simplification of the plant and a rationalization of the operation are obtained by the use of a manoeuvring apparatus with a gripper (26), which is both rotatable and slidable in at least two directions and which has elements of engagement (33, 34, 36) arranged to cooperate with corresponding engagement elements (47) on the parts to be manoeuvred; all the latter elements are uniform and placed in a specific manner so that the same manoeuvring apparatus can handle all the parts which are relevant as manoeuvring objects.

The frame of the device consists of corner racks, 1, upper longitudinal beams 2 and upper transverse beams 3 and 4. Two cylindrical guides 5 are parallel and at a short distance from the longitudinal beams 2 and are fixed between four brackets 6, two of which are attached to the corner posts 1, and the other two to the crossbeam 4. The carriage 7 is suspended from the guides 8 by means of Hecymjix and slides between two positions at the respective ends of the guides (-2518 by a distance equal to the piston travel
shown in solid and dashed lines in figures 1 and 2, respectively). This sliding can be carried out by two hydraulic cylinders 9 attached to one longitudinal beam 2 by means of a bracket 10. Between the cylinders 9 there is a toothed rack (not shown) which is coupled to the toothed sector (not shown) fixed on a vertical rotating shaft 11. A lever 12 is attached to the lower end of the shaft;

perpendicular to this plane. The two grippers are equipped with individual actuators and control mechanisms, rotated 180 ° from one pre-45 which have the same design of the individual position (Fig. 2) to the other, g function, his finger reciprocates in the guide groove 13, moving the carriage 7 from the limit position (shown by solid lines in FIG. 2) to the position shown by dashed lines.
The carriage 7 has downward side flanges 14 and 15, one of which 14 is slightly larger than the other. Two cylindrical transverse directions - 16 clamped between these flanges50

The gripper 28 is fixedly mounted on the rotating shaft 30. The shaft is mounted on the arm 31 at some axial distance from the gripper 28. Between the elements 28 and 31 is mounted a finger 32, on which one end of the rod 33 is mounted for rotation on a hinge 34 with a transverse head 35 at the free end of the rod 36 of the hydraulic cylinder 37, which is mounted rotatably in the middle between the two bearing arms 38.
, and on them, the upper horizontal portion 17 of the angular slider 18 is slidably mounted. Near one lower corner of the rectangular vertical portion 19 of the slider is attached with the possibility
rotating solid shaft 20, which carries the clamp 2 and can be rotated by a hydraulic, pneumatic, or electric drive mechanism (not shown) located in the vertical part of the slide 19.
On the top of the slide 18, two hydraulic cylinders 22 and 23 of different lengths are installed, which are directed in opposite directions, coaxial.
each other and parallel to the guides 16. The free end of the piston rod 24 of the short cylinder 22 is fixed to the high flange 14 of the carriage 7, and the free end of the piston rod 25 of the long cylinder 23 is attached to the base of the V-shaped clamp 26, the knee of which is attached to the slide block 8. Activation short cylinder 22 thus moves the slider
of this cylinder, on directions. 16 from the position shown in FIG. 3, and when the long cylinder 23 is activated, the slider additionally moves a distance equal to the larger stroke of the cylinder, across the movement path of the carriage 7. Activating the cylinders in the opposite direction leads to the two other indicated positions of the slider.
The clamp 21 (figure 4) has a casing 27, having the form of a relatively narrow duct, in which there is a shres in the same plane, the clamps 28 and 29 in the form
Elongated plates are mounted to rotate around the axes,
perpendicular to this plane. The two grippers are equipped with individual drives and control mechanisms, 45 which have the same construction} g function,

The gripper 28 is fixedly mounted on the rotating shaft 30. The shaft is mounted on the arm 31 at some axial distance from the gripper 28. Between the elements 28 and 31 is mounted a finger 32, on which one end of the rod 33 is mounted for rotation on a hinge 34 with a transverse head 35 at the free end of the rod 36 of the hydraulic cylinder 37, which is mounted rotatably in the middle between the two bearing arms 38.
On the hinge 34 there is a cam roller 39 which interacts with a cam plate 40 attached to the casing 27. In FIG. 4, the grippers are shown in solid lines in the working positions in which the notches 41 with their outward side edges engage the fingers 42 on the maneuverable a portion that is shown as a rectangular plate 43, which is, for example, a rod mask. In this position, the weight of the plate 43 creates an axial load on the gripper 28, which creates a torque in the clockwise direction (FIG. 4), causing the wheel 33 to bring the cam roller 39 into contact with the locking part 44 of the cam edge on the cam plate. The locking part forms an end stop for the cam roller and is separated from the remaining cam edge 45 by an edge 46, the center of the latter is roller 47, which is placed in the cam plate 48 and is under the action of the compression spring coil 49. The cam roller 39 can leave the locking block This part 44 only when the cylinder 37 pulls out its rod 36, so that the cam roller first deploys the ball 47, overcoming the action of the spring 49, and simultaneously rotates the thru 33 around the hinge 34 until the cam roller hooks the fixed n The control device 50, and then it follows the edge portion of the cam 45 under the combined action of the cylinder 37 and the weight of the gripper 28, until the piston 36 has reached its limit position. During this movement of the cam roller 39, the gripper 28 moves from the working position, shown in solid lines.
to the rest position shown by the stroke- 45 Ditc by moving the slide 18 along
These lines are completely located in the casing of the clamp 27. The shoulder 31 is provided with a backward extending part 51 with an adjustable locking device 52, which cooperates with the fixed stopper 53 to limit the rotational movement of the grip to the outside.
The other gripper 29 is shown in the working position by continuous lines and in the rest position by dashed lines. Since both grippers are in the same plane, their driving cylinders must be so controlled that the top 0

her shoulder was 28 watts before the lower shoulder 29.
The cam plate 40 is rotatably mounted on the shaft 54 and provided with a set screw 55 that engages the fixed stop 56 and thus allows the cam plate to be adjusted.
The engagement elements on the maneuverable parts can be formed, as shown in FIG. 5, where the part 57 is, for example, a template plate, the engagement element 42 has a cylindrical shaft 58 fixed in the hole in the plate 57, and the engagement part in The cylinder 59 is provided with an annular groove 60 of trapezoidal cross section. The edge part of the gripper 28, forming a notch 41, is made with a bevel 61 in order to have the same cross-section as the groove 60 in the cylindrical pin 59.
On the side facing the load, the clamps 28 and 29 have flat protrusions 62, which, in the gripping position, are in contact with the flat surface 0 of the load on which the hook-fingers 42 are placed to stabilize the load relative to the grips.
The engaging fingers 42 can also be used for fixing gauge plates or masks of rods in accumulators or anywhere else with the help of a holding device 63, which is mounted on the engaging fingers from the outside.
In Fig. 1, the carriage 7 and the clamp 21 are shown in a position in which the latter holds the rod mask 43 ready for feeding the rods into the mold 64. The feeding of the rods can be produced
when the carriage 7 is in the position shown by dashed lines — Q m (FIG. 1), the slider movements can, for example, be used to remove rod masks or pattern plates, or individual large rods from the drive or to feed it. The ability of the clamp 21 to rotate around the axis of the shaft 20 also allows it to be used for lifting rod masks from the conveyor belt on which they are fed, and for 5

thereby automatically giving them the feed position of the rods. In addition, rod masks or the like can be placed on the conveyor belt for further transport.
