    in meters, a double value from the axis of rotation to the rotary axis, and η is the number of axial revolutions per minute of the drum containers 7, 8, which is less than the number of revolutions at which the mass sticks to the inner surface of the drum container, and a resultant force is created equal to C A γ ζ 42C] where Υ is defined as the resultant force that must be created by the centrifugal force, combined with the action of gravity, and which is communicated to the mass inside the drum container.

    The invention relates to finishing of workpieces by means of rotating drums, and more particularly to a method in which the inside of said rotating drum with centrifugal force created, which provides improved efficiency and uniformity of finish machining workpieces. c
    The purpose of the invention is to improve the quality of processing billets
    FIG. 1 presents a conceptual diagram that illustrates how the forces created |
    during the normal finishing process in a centrifugal drum; in fig. 2 - the action of the forces created according to the proposed method; in fig. 3 - the same, the relationship between the cent- robustness and gravity x; Fig 4 - a device for the implementation of the proposed method, front view; Fig 5 - the same, top view; in fig. 6 - the same, a cut in the area of на · main nala.
    The drum container has a polygonal cylindrical shape with many sides (FIG. 2), preferably 6 or 8, since they are easier to manufacture. The drum container is the enemy (it sits on its horizontal shaft and is inserted into the head, which rotates on its main axis so that the drum container can rotate around the head on a plane including the container shafts and the bone head. To create a centrifugal force 10, the central section through the drum container, which flows perpendicular to its horizontaloneNomu shaft, must take the resultant force a1 -C '(force consisting of centrifugal force and the action of gravity). In case of equality of the ratio of the force of gravity and centrifugal force to the value of x, the resultant force is equal to 1+ χ2 in (Fig. 3). Values -} 2С * and 41 + х2 C ’remain constant at each orbital point of rotation
    drum container around the head. Thus, a uniform and constant layer of mass flow is formed, which provides an increase in the efficiency of finishing with high accuracy. For finishing in a rotating drum, forces act on the mass; ’, gravity, according to the proposed method, the centrifugal force created by rotating the head, is combined with the action of gravity. Since the direction of the centrifugal force remains unchanged at each point of rotation of the drum container around the head, the finishing efficiency is higher than when machining a rotating drum.
    The number of revolutions of the drum container around its shaft can be any, depending on the different requirements of finishing, its upper limit can be increased to a higher value than is possible with conventional finishing methods in a rotating drum (η / Ν = -1). Any intentional change in the direction of the axial rotation of the drum container only leads to a change in the position of the mass inside the drum container. The way mass flows remains unchanged, regardless of the direction of rotation.
    The table shows the classification of the operating modes of the finishing operations in the drum.
    I
    The device for implementing the proposed method comprises a frame, inside which the main shaft 1, the main engine 2, the sprocket and chain 3 for driving the main shaft 1 are vertically mounted with its sprocket 4. The speed of the main shaft 1 is variably adjusted using a known frequency inverter. The lower end of the main shaft 1 rests on the bearing 5, and the upper end on the bearing 6 “On the main shaft 1 there is a head 7, which is rigidly attached to the middle part of the main shaft 1. The head 7 is made in the form of an H-shaped plane with two pairs of levers extending outwards.
    5 A drum container 8 or 9 is attached to each pair of levers, which rotates between the respective levers forming the pair. In the head 7 are placed two. drum containers 8 and 9, but three or four drum containers can be placed.
    The main shaft 1 contains a sleeve 10 (FIG. 6), which rotates around the main shaft 1. At the lower end of the sleeve 10 there is a bevel gear 11, and at the upper end of the sleeve 10 there is a sprocket 12. The sprocket 12 has a drive connection to the drive system, which turns on the drive
    1614 754
    engine 13, reduction gears 14, sprocket 15 and chain 16. Bevel gear 11 on hub 10 engages bevel gear 17, each of which has its own shaft 18 and 19, which is located in head 7. Each of shafts 18 and 19 goes out through the head 7, and at the projecting end of each shaft there is a pulley 20, which is connected with a V-belt with a pulley 21 mounted on each of the shafts 22 and 23, on which the corresponding drum containers 8 and 9 are suspended. and 17 (p. 17 / p. 11) and rel. The diameter of the pulleys 20 and 21 (p 17 x p 21 / n 11 hp 20) as the product of p 21 / η 20 multiplied by the gear ratio η 17 / n 11 determines the value of η / Ν for drum containers (where η and N are this number of turns of drum containers and heads). It is assumed that η 17 / n 11 = 1/2; n 21 / n 20 = 2; η / Ν = 1. In this case, each drum container completes its axial rotation after the head has passed one full turn, and the drum container is oriented in the same direction as it was before the head went one full turn.
    If the ratio η / Ν is an integer, then the drum container has the same orientation in which it was before the start of the finishing operation, when the head should be stopped in a predetermined position. In the example shown, the drum container is stopped so that its lid is located on the upper side. This is especially useful with automatic handling of mass. The value of η / Ν can be changed to ensure the corresponding speed and the corresponding direction of rotation by simultaneously turning on the main engine 2 of the head and the engine of the 24 drums. The number of revolutions n must be lower than the value above which the mass in the drum forcibly adheres to the wall of the drum during the rotation of the drum container. ”This number of revolutions creates the resultant force —Y! + x g C (where x is the ratio of centrifugal force and gravity at 0 x έ 1), of which for (0 Ь - ^ / g (where CO is the angular velocity, rad / s);
    r - radius of rotation of the mass, p - to speed nis gravity) we obtain η = 42,2 * χ (^ Ί + X 2) r le 7 P -. n the diameter of the inscribed polygonal circumference of the drum, m may be any number of revolutions below the specified value, and the drum container mo, 0
    It can rotate in any direction. Each drum container 3 and 9 may contain a mass that actually fills the volume of the drum by half, and the main shaft 1 rotates at a speed less than N = 42.2 / - ^ 17,
    15 to give rise to piling the resultant force 5 <Vc <2 C '(where Υ - resultant force) which communicates the mass. Thus, a flow layer is formed on the surface of the mass, which ensures that the workpiece is processed with high accuracy under the influence of a large resultant force. When the head rotates at high speed and the sleeve 10 does not rotate, the function of pure drum processing with centrifugal flow occurs. On the contrary, when the sleeve 10 rotates and the head does not rotate, only the rotation of the drum 9 around them occurs. In this case, finishing works in a rotating drum.
    The proposed method provides various Finishing Functions, such as centrifugal flow drum finishing, rotating drum rotation under the influence of a large resultant force and conventional finishing in a rotating drum, which can be performed in any sequence. In particular, these operations, which include these various processes, are performed on one machine 5, and the steps are implemented on any
    suitable programmable sequence controller or microprocessor. Thus, operations are carried out in any order 50 and under various finishing conditions.
