Description

Technical Field

[0001] The invention relates to the technical field of aluminum alloy slurry preparation, and in particular to a device and method for preparing semi-solid aluminum alloy slurry. Background Art

[0002] Semi-solid slurrying of aluminum alloy is an advanced aluminum alloy forming process. Semi-solid metal slurry is used to make parts with the advantages of high strength, high toughness and excellent forming performance.

DETAILED DESCRIPTION

[0042] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0043] See also Figures 1 to 6 In an embodiment of the present invention, a device for preparing a semi-solid aluminum alloy slurry includes a crucible 400 and an electromagnetic induction component 500 disposed outside the crucible 400.

[0044] Specifically, the offset module 170 drives the socket 180 to move relative to the rotating frame 160, and the socket 180 drives the bottom end of the mounting frame 300 to tilt when moving along the rotating frame 160, thereby controlling the tilt angle of the crucible 400, and then the rotating frame 160 is driven to rotate by the two driving modules 120, and the rotating frame 160 drives the socket 180 to revolve, thereby driving the crucible 400 to revolve through the mounting frame 300, so that the crucible 400 revolves in a tilted state, and the tilted revolution of the crucible 400 drives the aluminum alloy liquid to rotate in the crucible 400, thereby accelerating the rotation and mixing of the aluminum alloy and improving production efficiency.

[0045] Embodiment 1

[0046] like Figures 1 to 6 As shown, in this embodiment, the offset module 170 includes a frame 171, an internal threaded sleeve 172, and a screw 173. The frame 171 is arranged between the inner walls on both sides of the rotating frame 160. The sleeve seat 180 is rotatably connected to the frame 171. There are two internal threaded sleeves 172, and the two internal threaded sleeves 172 are respectively fixed to the two end positions of the frame 171. There are two screws 173, and the two screws 173 are located at the two end positions of the rotating frame 160. The screw 173 is rotatably connected to the rotating frame 160. One end of the screw 173 is screwed and connected with the adjacent internal threaded sleeve 172. The other end of the screw 173 is fixedly sleeved with an intermediate gear 174. The intermediate gear 174 is located between the two annular gear racks 130. 4 is meshed with the annular gear rack 130, both sides of the outer wall of the sleeve seat 180 are fixedly connected with sliding shafts 182, and the sliding shafts 182 are rotatably plugged with the frame 171, and the outer walls of both sides of the rotating frame 160 are provided with long grooves 161, and the sliding shafts 182 are slidably connected with the inner walls of the long grooves 161, and the placement frame 300 includes a ball piece 320, and the ball piece 320 is movably connected with the spherical seat 200, and the bottom end of the ball piece 320 is fixedly connected with a bottom rod 310, and the outer wall of the bottom end of the bottom rod 310 is provided with a sliding groove 311, and the sliding seat 181 is slidably sleeved with the bottom end of the bottom rod 310, and the top of the ball piece 320 is fixedly connected with a bracket 330, and the bracket 330 is used to support the crucible 400, and the top outer diameter of the inner contour of the crucible 400 is larger than the bottom outer diameter;

[0047] The driving module 120 includes a driving motor 121 and a driving gear ring 123. The driving motor 121 is fixedly mounted on the driving mechanism 100. The output end of the driving motor 121 is fixedly sleeved with a driving gear 122. The driving gear ring 123 is fixedly sleeved on the outer wall of the adjacent annular gear rack 130, and the driving gear 122 and the driving gear ring 123 are meshed.

[0048] In this embodiment, the driving motor 121 drives the driving gear ring 123 to rotate through the driving gear 122, and the driving gear ring 123 drives the annular gear rack 130 to rotate. Since the two annular gear racks 130 are meshed with the intermediate gear 174 at the same time, when the two driving motors 121 are controlled to be driven synchronously, the two annular gear racks 130 rotate synchronously, thereby driving the rotating frame 160 to rotate through the intermediate gear 174, and the intermediate gear 174 is in a state of stopping rotation. When the rotating frame 160 revolves, it drives the sleeve seat 180 to revolve. When the inclination angle of the crucible 400 needs to be adjusted, the rotation speed of the two driving motors 121 is controlled so that a speed difference occurs between the two annular gear racks 130, so that the two annular gear racks 130 are staggered, thereby The intermediate gear 174 is driven to rotate, and the rotation of the intermediate gear 174 drives the screw 173 to rotate. The screw 173 drives the frame 171 to slide along the rotating frame 160 through the internal threaded sleeve 172, thereby driving the socket 180 to move along the length direction of the rotating frame 160. When the socket 180 moves, it drives the placement frame 300 to tilt through the bottom rod 310, thereby adjusting the tilt angle of the crucible 400. When the crucible 400 tilts to one side, the aluminum alloy liquid on one side surges up and the aluminum alloy liquid on the other side surges down, so that the aluminum alloy liquid flows in the vertical direction. The top outer diameter of the inner contour of the crucible 400 is set to be larger than the bottom outer diameter, so that the center position height of the liquid surface of the crucible 400 does not change when the crucible 400 is tilted, which facilitates the flow of the aluminum alloy liquid.

[0049] The present invention also provides an operating method for preparing a semi-solid aluminum alloy slurry, which specifically comprises the following steps:

[0050] Step 1: Start the electromagnetic heating coil in the crucible 400 to preheat the crucible 400;

[0051] Step 2: pouring aluminum alloy liquid into the crucible 400;

[0052] Step 3: Start the electromagnetic induction component 500 to generate a magnetic field to drive the aluminum alloy liquid to rotate in the crucible 400. At the same time, the driving mechanism 100 drives the crucible 400 to tilt at a certain angle and drives the crucible 400 to revolve, thereby accelerating the stirring of the aluminum alloy liquid.

[0053] Embodiment 2

[0054] On the basis of the first embodiment, in order to compensate for the effect that the socket 180 in the first embodiment revolves, the bottom rod 310 is driven to rotate to prevent the crucible 400 from rotating, so as to facilitate the connection between the electromagnetic coil on the crucible 400 and the outside world.

[0055] like Figures 4 to 9As shown, in this embodiment, a correction module 190 is provided on one side of the rotating frame 160, and a positioning ring frame 140 is fixedly connected to the inner side wall of the mounting frame 110, and the positioning ring frame 140 is located between the two annular gear frames 130. The correction module 190 includes a bevel gear 191, a bevel gear 192, a telescopic transmission assembly 193, a connecting seat 194, and a reversing assembly 195. The bevel gear 191 is fixedly sleeved at the top position of the sliding seat 181, and the bevel gear 192 is rotatably connected to the outer side wall of a sliding shaft 182. The bevel gear 2 192 is meshed with the bevel gear 1 191, the telescopic transmission assembly 193 is fixedly mounted on a side wall of the frame 171, the telescopic transmission assembly 193 is transmission-connected with the bevel gear 2 192, the connecting seat 194 is fixedly connected to one end of a side wall of the rotating frame 160, the reversing assembly 195 is mounted on the connecting seat 194, and the reversing assembly 195 is meshed with the positioning ring frame 140, the reversing assembly 195 is transmission-connected with the telescopic transmission assembly 193, and the telescopic transmission assembly 193 includes a secondary rod 1932, One end of the auxiliary rod 1932 is rotatably connected to a side wall of the frame 171, one end of the auxiliary rod 1932 is fixedly sleeved with a bevel gear 4 1933, a side wall of the bevel gear 2 192 is fixedly connected with a bevel gear 3 1931, the bevel gear 3 1931 is meshed with the auxiliary rod 1932, the other end of the auxiliary rod 1932 is slidably connected to the main rod 1934, one end of the main rod 1934 is rotatably connected to one end of a side wall of the rotating frame 160, the outer side wall of one end of the main rod 1934 is fixedly sleeved with a bevel gear 5 1935, and the reversing group Component 195 includes a flat gear 2 1952 and a bevel gear 6 1954. The flat gear 2 1952 and the bevel gear 6 1954 are both rotatably connected to the connecting seat 194. The bottom end of the bevel gear 6 1954 is fixedly connected to the flat gear 3 1953. The bottom side of the flat gear 2 1952 is fixedly connected to the flat gear 1 1951. The flat gear 1 1951 is meshed with the inner wall of the positioning ring frame 140. The flat gear 2 1952 is meshed with the flat gear 3 1953. The bevel gear 6 1954 is meshed with the bevel gear 5 1935.

[0056] In a specific implementation, when the rotating frame 160 rotates forward, the flat gear 1 1951 rotates forward while rotating in the reverse direction. The flat gear 1 1951 drives the flat gear 3 1953 to rotate forward through the flat gear 2 1952. The flat gear 3 1953 drives the bevel gear 4 1933 to rotate in the reverse direction through the bevel gear 5 1935. The bevel gear 4 1933 drives the bevel gear 1 191 to rotate in the reverse direction through the bevel gear 3 1931 and the bevel gear 2 192. When the rotating frame 160 rotates forward one circle, When the bottom bar 310 is tilted, the bevel gear 191 rotates in the opposite direction for one circle, so that the bottom bar 310 can offset the rotation generated during the revolution by rotating in the opposite direction for one circle, thereby preventing the crucible 400 from rotating during the revolution. When the inclination angle of the bottom bar 310 changes, the bevel gear 191 revolves around the bevel gear 2 192, so that the bevel gear 191 rotates. Although the crucible 400 will rotate at an angle equal to the inclination angle when the inclination angle is adjusted, it does not affect the connection between the crucible 400 and the outside world.
