Obviously, the described embodiments are part of the embodiments of the present invention, rather than all of the embodiments. The components of the embodiments of the present invention described and shown in the drawings here can usually be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present invention provided in the drawings is not intended to limit the scope of the claimed invention, but merely represents selected embodiments of the present invention. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0040] The overall working principle of the rotary vibration coupling stirring device for semi-solid slurry of the present invention is:

[0041] The aluminum alloy is put into the smelting furnace, and after being heated to the set temperature, it is drained into the barrel through the feed port through the pipeline. The first motor and the second motor are turned on at the same time. The first motor drives the worm gear transmission system to move through the gear transmission, and at the same time transmits power to the pear claw telescopic mechanism and the planetary gear system. The pear claw telescopic mechanism is provided with an eccentric disk, which can achieve the expected goals such as the rotation, revolution and vibration of the stirring rod. When the slurry enters the barrel, the second motor is turned on at the same time. The second motor drives the disc cam mechanism and the bevel gear reciprocating mechanism to move at the same time, which can achieve the expected goals such as the rotation, revolution and vibration of the barrel. The two devices have opposite rotation directions and symmetrical vibration in the vertical direction, so that the slurry can have greater shear force during the stirring process, which improves the efficiency and quality of preparing semi-solid billets of metals and alloys.

[0042] The working principle of the first power system is:

[0043] The first motor outputs power, which is meshed with the first active bevel gear and the first driven bevel gear to the main transmission shaft, and the main transmission shaft transmits the power to the barrel rotation vibration device 2 and the barrel Y-axis vibration device 3 to realize the rotation of the barrel and the X and Y-axis vibration movement.

[0044] The working principle of the barrel rotating vibration device 2 is:

[0045] The power is output by the first power system 1, and is transmitted to the main transmission shaft 35 through the bevel gear meshing transmission. The main transmission shaft 35 transmits the power to the rotating disk 23 and the disk cam 24, so that the rotating disk 23 and the disk cam 24 can realize rotational motion; at the same time, the disk cam 24 is set at the center position of the connecting shafts 22 on both sides and contacts with the connecting shafts 22. The connecting shafts 22 are fixed on the sliding plate 21, and the sliding plate 21 can reciprocate in the chute at the middle position of the rotating disk 23; so when the main transmission shaft 35 rotates, the rotating disk 23 and the disk cam 24 will rotate accordingly. At the same time, due to the position restriction of the connecting shafts 22 on both sides, when the disk cam 24 rotates, the sliding plate 22 can realize the reciprocating motion of the sliding plate 22 in the chute. This device uses the mechanism of the disk cam and the crank slider to cleverly realize the rotational motion of the barrel and the reciprocating motion in the X direction.

[0046] The working principle of the barrel Y-axis vibration device 3 is:

[0047] The lower end of the driving shaft 35 is connected to the barrel rotating vibration device, and the upper end is connected to the driving bevel gear 33 of the filter disc 32 in turn, which plays the role of transmitting power; a driven shaft 36 is fixedly connected to the left side of the driving shaft 35 in the radial direction, and the driven bevel gear 34 is connected to the driven shaft 36 through a key connection, and a slider 37 is eccentrically fixed on the driven bevel gear 34; as the driving shaft 35 rotates, the driving bevel gear 33 meshes with the driven bevel gear 34, and the slider 37 eccentrically fixed on the driven bevel gear 34 is placed in the slide groove inside the barrel housing 31. As the driven bevel gear 34 rotates and revolves, the distance between the slider and the center of the driven bevel gear 34 changes, thereby realizing the Y-direction reciprocating motion of the barrel by using the slide groove. This device uses an eccentrically set slider to cooperate with the barrel slide groove, and uses a motion mechanism similar to a crank slider to realize the Y-direction vibration of the barrel.

[0048] The working principle of the inner stirring device of the stirring plate is:

[0049] The stirring rod adopts impact-free vibration technology, that is, a flow ball structure, a special eccentric cavity, and a steel ball and anti-wear agent inside, which replaces the eccentric block of the swing block vibrator, and generates large and small vibrations through the movement displacement of the steel ball; when starting and stopping vibration, the steel ball can achieve flexible start and stop under the buffering of the anti-wear agent, avoiding the instantaneous impact of the steel ball hitting the stirring rod wall when starting and stopping vibration, and eliminating the risk of the stirring rod breaking; avoiding the impact of starting and stopping vibration, while effectively extending the service life of the stirring rod and steel ball, ensuring the high reliability of the vibration system.

[0050] The working principle of the stirring rotation vibration device 5 is:

[0051] Rotating stirring and vibrating device. The driven shaft 86 is connected to the center wheel 54 in the stirring and vibrating device 5 through a key connection; the plow claw plate 51 is connected to the driven shaft 86 through a sleeve, and a fixing groove is opened on the outer circle of the plow claw plate 51 to fix the planetary carrier 53; while the planetary wheel 55 is meshed with the center wheel 54 and the planetary carrier 53, a connecting rod 52 is used, one end of a rod is eccentrically connected to the planetary wheel 55, and the other end is connected to two rods; one end of the two rods is connected to a rod, and the other end is provided with a slider placed inside the slide groove of the plow claw plate 51; the outer ring stirring rod It is connected to the position where the connecting rod 52 and the planetary wheel 55 are connected, and the connecting rod 52 and the planetary wheel 55 are connected at the eccentric position of the planetary wheel 55; when the driven shaft 86 rotates, the center wheel 54 is driven to rotate, and at the same time, because the planetary frame 53 is fixed on the plow claw plate 51, the planetary wheel 55 can realize rotation and revolution; and because the stirring rod is eccentrically connected to the planetary wheel 55, when the planetary wheel 55 rotates, the radial distance between the stirring rod and the center wheel 54 changes, which is equivalent to realizing the vibration movement of the stirring rod in the X direction. This device uses the eccentric connection and the movement mechanism of the planetary gear system to cleverly realize the rotation movement and X-direction vibration of the stirring rod.

[0052] Principle of stirring vibration device:

[0053] The stirring vibration device is a double worm gear mechanism. One end of the main transmission shaft 81 is connected to the driven bevel gear, and the other end is connected to the bracket through a bearing. The driving spur gear 82 is connected to the driving shaft 81 through a key connection to transmit power to the worm gear; one end of the driven shaft 86 is connected to the driven spur gear 83 through a key, and the other end is connected to the planetary gear system; at the same time, two groups of worm gears are arranged on the driving shaft 81 and the driven shaft 86 in parallel, the driving worm 85 is connected to the driving shaft 81, and the driven worm 88 is connected to the driven shaft 86; the driving turbine 84 is meshed with the driving worm 85, and the driven turbine 87 is meshed with the driven worm 88. At the same time, the driving turbine 84 and the driven turbine 87 are eccentrically connected through a connecting rod mechanism, which can realize the rotational motion of the driven worm 88 and the reciprocating motion in the Y direction when the worm gear is meshed. This method of the device utilizes the characteristics of the worm gear meshing and the double turbine eccentric connection motion trajectory, and cleverly realizes the vibration effect of the stirring device in the Y direction.

[0054] Working principle of the second power system:

[0055] The second driving bevel gear arranged on the output shaft of the motor in the second power system is meshed and connected with the first driven bevel gear for transmission. The power is transmitted to the driving shaft, and the second driven bevel gear and the driving spur gear are arranged on the driving shaft in sequence. The driving spur gear and the driven spur gear are meshed and connected to transmit power to the worm gear.
