Description

Technical Field

[0001] The invention relates to the field of casting and pouring, and in particular to a tilting pouring ladle. Background Art

[0002] The pouring ladle is a pouring accessory used in metal foundries. It is mainly used to hold and transport molten metal, such as molten iron or molten steel, into the mold for pouring. It plays a vital role in the casting process, ensuring that the molten metal can be smoothly transferred from the pouring ladle to the mold to form the desired casting.

[0003] For example, the invention patent with publication number CN118492351 B discloses a tilting double molten iron outlet automatic pouring machine, including a flat car track, and also includes: a pouring ladle for holding molten iron for pouring, the pouring ladle has two adjustable pouring buckets; a moving system installed on the flat car track, used to drive the pouring ladle to perform three-axis linkage to adjust the pouring position; a pouring ladle tilting system, the moving system drives the pouring ladle tilting system to move synchronously with the pouring ladle, the pouring ladle tilting system is used to drive the pouring ladle to tilt for pouring; a flow inoculation system, which is used to inject the molten iron into the pouring ladle after the corresponding inoculant according to the amount of molten iron to be poured is linked to the sand box to complete the molten iron inoculation.

[0004] The above case has the following defects: during the pouring process of the pouring ladle, the pouring ladle will be driven to rotate. During the rotation of the pouring ladle, the molten iron in the pouring ladle is poured out from the pouring ladle. At this time, the pouring ladle is in a tilted state. Under the action of the gravity of the molten iron, the pouring ladle generates a thrust to flip downward, which can easily cause the pouring ladle to rotate too much, causing the molten iron in the pouring ladle to overflow from the pouring ladle.

[0005] Therefore, the present invention proposes a tilting pouring ladle to solve the above problems. Summary of the invention

[0006] In order to achieve the above objectives, the technical solution adopted by the present invention is: a tilting pouring ladle, comprising:

[0007] A U-shaped bracket, the side wall of which is rotatably connected to a pouring container bag;

[0008] A casing, wherein the casing is fixedly connected to a side wall of the U-shaped bracket;

[0009] A three-stage reduction turbine, the three-stage reduction turbine being rotatably connected in the casing;

At this time, under the action of the mutual meshing of the secondary reduction worm and the tertiary reduction turbine, the self-locking of the pouring container package is completed, thereby ensuring that the pouring container package remains stable during the movement, avoiding the molten iron overflowing from the top opening of the pouring container package, and avoiding the waste of molten iron.

[0038] Compared with the prior art, the present invention has the following beneficial effects:

[0039] 1. The present invention provides a three-stage reduction turbine and a two-stage reduction worm. When the two-stage reduction worm rotates, due to the effect of friction, the three-stage reduction turbine will fit tightly on the two-stage reduction worm, thereby preventing the three-stage reduction turbine from rotating unexpectedly, which is beneficial to hindering the accidental rotation of the pouring container bag and avoiding the accidental increase of the inclination angle of the pouring container bag, which causes excess molten iron to overflow from the top opening of the pouring container bag and cause waste.

[0040] 2. The present invention provides a first-stage reduction turbine and a transmission worm. On the one hand, the pouring container bag is decelerated so that the pouring container bag can rotate slowly during rotation, thereby preventing the pouring container bag from turning over too quickly and causing molten iron to splash. On the other hand, the self-locking strength is further increased, which is beneficial to hindering accidental rotation of the pouring container bag and avoiding an increase in the rotation amplitude of the pouring container bag, which causes excess molten iron to overflow from the top opening of the pouring container bag and cause waste.

[0041] 3. The present invention sets a mounting shaft and a sleeve. After the pouring container bag is filled with molten iron, the cylinder is started, so that the telescopic rod of the cylinder pulls the pouring container bag to move, so that the sleeve moves along the surface of the mounting shaft, and the connecting pin moves along the driving groove. The connecting pin first moves along the first straight groove and then enters the first arc-shaped inclined groove. Driven by the first arc-shaped inclined groove, the pouring container bag rotates in the opposite direction, reducing the inclination angle of the pouring container bag, thereby further improving the stability of the molten iron in the pouring container bag and avoiding the problem of molten iron overflowing and wasting during the movement of the pouring container bag.

[0042] 4. The present invention sets a main shaft, a first sub-shaft and a second sub-shaft. When the pouring container package completes the first pouring and the second pouring respectively, the connecting pin moves along the second arc-shaped inclined groove on the first sub-shaft and the third arc-shaped inclined groove on the second sub-shaft respectively, so that the greater the rotation angle of the pouring container package, the greater the reverse reset rotation angle, thereby further avoiding the problem of molten iron overflowing and causing waste during the movement of the pouring container package.

DETAILED DESCRIPTION

[0052] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are only examples, and those skilled in the art may think of other obvious variations.

[0053] like Figures 1 to 8 A tilting pouring ladle is shown, comprising:

[0054] A U-shaped bracket 1, the side wall of which is rotatably connected to a pouring container package 3;

[0055] A housing 5, wherein the housing 5 is fixedly connected to a side wall of the U-shaped bracket 1;

[0056] A three-stage reduction turbine 6, which is rotatably connected in the casing 5;

[0057] A two-stage reduction worm 7, both ends of which are rotatably connected in the casing 5, and the two-stage reduction worm 7 is meshed with the three-stage reduction turbine 6;

[0058] A connecting shaft 8, one end of which is coaxially fixed to the three-stage reduction turbine 6, and the other end of which is fixedly connected to a coupling assembly, which is fixedly connected to the outer wall of the pouring container package 3;

[0059] A driving assembly, the driving assembly is used to drive the secondary reduction worm 7 to rotate, so as to drive the tertiary reduction turbine 6 to rotate;

[0060] It should be noted that the inclination angle of the secondary reduction worm 7 is greater than the pressure angle of the tertiary reduction turbine 6;

[0061] Specifically, in the prior art, during the pouring process of the pouring ladle, the pouring ladle is driven to rotate. During the rotation of the pouring ladle, the molten iron in the pouring ladle is poured out from the pouring ladle. At this time, the pouring ladle is in an inclined state. Under the action of the gravity of the molten iron, the pouring ladle generates a thrust to flip downward, which easily causes the pouring ladle to rotate too much, causing the molten iron in the pouring ladle to overflow from the pouring ladle. The technical solution can solve the above problem, and the specific operation is as follows:

[0062] During the pouring process, the secondary reduction worm 7 is rotated by starting the rotary drive component. Since the secondary reduction worm 7 is meshed with the tertiary reduction turbine 6, the tertiary reduction turbine 6 is driven to rotate. Driven by the connecting shaft 8 and the coupling assembly, the pouring container bag 3 is rotated, so that the molten iron in the pouring container bag 3 is poured out; when the secondary reduction worm 7 rotates, due to the effect of friction, the tertiary reduction turbine 6 will fit tightly on the secondary reduction worm 7, thereby preventing the accidental rotation of the tertiary reduction turbine 6, which is beneficial to hindering the accidental rotation of the pouring container bag 3 and avoiding the accidental increase in the rotation amplitude of the pouring container bag 3, resulting in excess molten iron overflowing from the pouring container bag 3, causing waste; after the molten iron stops pouring, the rotary drive component is closed, and the pouring container bag 3 stops pouring. At this time, under the action of the mutual meshing of the secondary reduction worm 7 and the tertiary reduction turbine 6, the self-locking of the pouring container bag 3 is completed, thereby ensuring that the pouring container bag 3 remains stable during the movement, avoiding the molten iron overflowing from the top of the pouring container bag 3, and avoiding the waste of molten iron.

[0063] As a further embodiment of the present invention, the drive assembly comprises:

[0064] The first-stage reduction turbine 9 is fixedly connected to the second-stage reduction worm 7;

[0065] A transmission worm 10, both ends of which are rotatably connected in the casing 5, and the transmission worm 10 is meshed with the first-stage reduction turbine 9;

[0066] The reduction motor 11 is fixedly connected in the housing 5, and the output shaft end of the reduction motor 11 and the end of the driving worm 10 are jointly driven by a chain 12;

[0067] It should be noted that the inclination angle of the transmission worm 10 is greater than the pressure angle of the first-stage reduction turbine 9. In addition, sprockets are fixed on the output shaft of the reduction motor 11 and the transmission worm 10, and the chain 12 is arranged between the two sprockets.

[0068] Specifically, during the pouring process, the reduction motor 11 is started so that the output shaft of the reduction motor 11 rotates, and under the transmission of the chain 12, the transmission worm 10 rotates, thereby driving the first-stage reduction turbine 9 to rotate, so that the second-stage reduction worm 7 rotates, and thus the third-stage reduction turbine 6 rotates. Under the cooperation of the transmission worm 10 and the first-stage reduction turbine 9, on the one hand, the pouring container package 3 is decelerated so that the pouring container package 3 can be slowly turned over during rotation, thereby avoiding the pouring container package 3 from turning over too fast and causing molten iron to splash; on the other hand, the self-locking strength is further increased, which is conducive to preventing the pouring container package 3 from accidentally rotating and avoiding the pouring container package 3 from accidentally increasing the rotation amplitude, causing excess molten iron to overflow from the pouring container package 3 and causing waste.

[0069] As an optional implementation scheme of the coupling assembly, a cylinder 13 is fixedly connected to the side wall of the U-shaped bracket 1, and a telescopic rod of the cylinder 13 is rotatably connected to the outer side wall of the pouring container package 3;

[0070] The coupling assembly includes:

[0071] A mounting shaft 14, one end of which is fixedly connected to the end of the connecting shaft 8, and a driving groove is symmetrically opened on the surface of the mounting shaft 14, and the driving groove includes a first straight groove 15 and a first arc-shaped oblique groove 16, wherein the first straight groove 15 is close to the connecting shaft 8 and the first arc-shaped oblique groove 16 is close to the shaft sleeve 17;

[0072] A shaft sleeve 17, the shaft sleeve 17 is slidably connected to the surface of the mounting shaft 14, one end of the shaft sleeve 17 is fixedly connected to the outer wall of the pouring container package 3, and a connecting pin 18 is symmetrically fixedly connected to the inner side of the shaft sleeve 17, and the connecting pin 18 is slidably connected in the driving groove;

[0073] Specifically, after the pouring container bag 3 has finished pouring the molten iron, the cylinder 13 is started, so that the telescopic rod of the cylinder 13 pulls the pouring container bag 3 to move, so that the shaft sleeve 17 moves along the surface of the mounting shaft 14, and the connecting pin 18 moves along the driving groove. The connecting pin 18 first moves along the first straight groove 15, and then enters the first arc-shaped inclined groove 16. Driven by the first arc-shaped inclined groove 16, the pouring container bag 3 rotates in the opposite direction, which can reduce the inclination angle of the pouring container bag 3, thereby further improving the stability of the molten iron in the pouring container bag 3, and avoiding the problem of molten iron overflowing and causing waste during the movement of the pouring container bag 3;

[0074] After the pouring container package 3 moves to the next pouring position, the telescopic rod of the cylinder 13 pushes the pouring container package 3, so that the sleeve 17 moves along the surface of the mounting shaft 14, and the connecting pin 18 first moves along the first arc-shaped inclined groove 16, and then the connecting pin 18 enters the first straight groove 15. Driven by the first arc-shaped inclined groove 16, the pouring container package 3 rotates forward and quickly returns to the last tilted position. Then, under the clamping limit action of the first straight groove 15, the reduction motor 11 is started to make the pouring container package 3 continue to rotate, increasing the tilt angle of the pouring container package 3, thereby continuing to pour out the molten iron and completing the pouring at the current position.

[0075] As another embodiment of the coupling assembly,

[0076] The side wall of the U-shaped bracket 1 is fixedly connected with a cylinder 13, and the telescopic rod of the cylinder 13 is rotatably connected with the outer side wall of the pouring container package 3;

[0077] The coupling assembly includes:

[0078] The main shaft 19 is fixedly connected to the end of the connecting shaft 8, and the surface of the main shaft 19 is symmetrically provided with a second straight groove 20, and the surface of the main shaft 19 is provided with a first clearance groove 21;

[0079] A first secondary shaft 23, the first secondary shaft 23 is rotatably connected to the end of the main shaft 19, the end of the first secondary shaft 23 is fixedly connected to a first connecting rod 27 at the position of the first clearance groove 21, the end of the first connecting rod 27 is slidably connected to the side wall of the U-shaped bracket 1, an elastic connecting piece is provided between the first connecting rod 27 and the U-shaped bracket 1, and a second arc-shaped inclined groove 24 is symmetrically opened on the surface of the first secondary shaft 23;

[0080] A shaft sleeve 17, the shaft sleeve 17 is slidably connected to the surface of the main shaft 19, one end of the shaft sleeve 17 is fixedly connected to the outer wall of the pouring container package 3, and a connecting pin 18 is symmetrically fixedly connected to the inner side of the shaft sleeve 17, and the connecting pin 18 is slidably connected to the second straight groove 20;

[0081] Also includes:

[0082] A second clearance groove 22, which is formed on the surface of the main shaft 19;

[0083] A third paving groove 25, which is located on the surface of the first secondary shaft 23 at a position corresponding to the second paving groove 22;

[0084] A second secondary shaft 31, the second secondary shaft 31 is rotatably connected to the end of the main shaft 19, the end of the second secondary shaft 31 is fixedly connected to a second connecting rod 35 at the position of the first clearance groove 21, the end of the second connecting rod 35 is fixed to the side wall of the U-shaped bracket 1, and a third arc-shaped inclined groove 32 is opened on the surface of the second secondary shaft 31;

[0085] Also includes:

[0086] Two third straight grooves 26, which are respectively opened on the surface of the first secondary shaft 23 at positions corresponding to the second straight grooves 20;

[0087] Two fourth straight grooves 33, which are respectively corresponding to the positions of the third straight grooves 26 and are opened on the surface of the second secondary shaft 31;

[0088] Also includes:

[0089] Two fifth straight grooves 34, which are formed on the surface of the second secondary shaft 31 at positions corresponding to the second arc-shaped inclined grooves 24;

[0090] Specifically, when the pouring container package 3 is in a vertical state, the second straight groove 20, the third straight groove 26 and the fourth straight groove 33 are connected. If the operator mistakenly starts the cylinder 13, the connecting pin 18 in the sleeve 17 moves continuously along the second straight groove 20, the third straight groove 26 and the fourth straight groove 33. At this time, the pouring container package 3 is still in a vertical state, avoiding the problem of accidental rotation of the pouring container package 3, which causes the molten iron to overflow.

[0091] During the first pouring of the pouring container package 3, the main shaft 19 rotates, so that the second straight groove 20 moves to the second arc-shaped inclined groove 24. After the first pouring is completed, the telescopic rod of the cylinder 13 pulls the pouring container package 3 to move, so that the connecting pin 18 moves along the second straight groove 20 and then enters the second arc-shaped inclined groove 24. Driven by the second arc-shaped inclined groove 24, the pouring container package 3 rotates in the opposite direction, reducing the inclination angle of the pouring container package 3, so that the molten iron level in the pouring container package 3 is away from the top port of the pouring container package 3, which is conducive to avoiding the overflow of molten iron during the movement of the pouring container package 3 and avoiding the waste of molten iron; then the connecting pin 18 enters the fifth straight groove 34. Since the second secondary shaft 31 is fixed on the U-shaped bracket 1, the state of the pouring container package 3 can be maintained under the limit of the fifth straight groove 34, thereby further improving the stability of the pouring container package 3;

[0092] After the pouring container package 3 moves to the next pouring position, the telescopic rod of the cylinder 13 pushes the pouring container package 3, so that the pouring container package 3 quickly returns to the last tilted position;

[0093] During the second pouring of the pouring container package 3, the main shaft 19 continues to rotate, causing the first secondary shaft 23 to rotate. After the second pouring is completed, the telescopic rod of the cylinder 13 continues to push, causing the connecting pin 18 to move along the second straight groove 20 and enter the second arc-shaped inclined groove 24 and the third arc-shaped inclined groove 32 respectively. Driven by the second arc-shaped inclined groove 24 and the third arc-shaped inclined groove 32, the reverse rotation angle of the pouring container package 3 is increased, thereby further avoiding the problem of molten iron overflowing and causing waste during the movement of the pouring container package 3.

[0094] As a further embodiment of the present invention, the elastic connecting member includes an arc groove 28, the arc groove 28 is opened on the side wall of the U-shaped bracket 1, an arc connecting rod 29 is fixedly connected in the arc groove 28, the first connecting rod 27 is slidably connected to the surface of the arc connecting rod 29, and an arc spring 30 is sleeved on the surface of the arc connecting rod 29, and the two ends of the arc spring 30 are respectively fixedly connected to the arc groove 28 and the first connecting rod 27;

[0095] Specifically, by providing an arc spring 30, after the pouring container package 3 completes two pourings, the main shaft 19 is driven by the connecting shaft 8 to rotate and reset, and under the action of the arc spring 30, the first secondary shaft 23 is reset to its original position, thereby ensuring that the second straight groove 20, the third straight groove 26 and the fourth straight groove 33 are in a connected state.

[0096] As a further embodiment of the present invention, it also includes two arc-shaped guide rails 2, which are symmetrically fixed on both sides of the U-shaped bracket 1, and the outer wall of the pouring container package 3 is symmetrically fixedly connected with a slider 4, and the slider 4 is slidably connected in the arc-shaped guide rails 2;

[0097] Specifically, by providing the arc guide rail 2 and the slider 4 , the rotation track of the pouring container package 3 is limited and supported, so as to improve the rotation stability of the pouring container package 3 .

[0098] Working principle of the present invention:

[0099] By starting the rotary drive assembly, the secondary reduction worm 7 is rotated. Since the secondary reduction worm 7 is meshed with the tertiary reduction turbine 6, the tertiary reduction turbine 6 is driven to rotate. Driven by the connecting shaft 8 and the coupling assembly, the pouring container bag 3 is rotated, so that the molten iron in the pouring container bag 3 is poured out; when the secondary reduction worm 7 rotates, due to the effect of friction, the tertiary reduction turbine 6 will fit tightly on the secondary reduction worm 7, thereby preventing the accidental rotation of the tertiary reduction turbine 6, which is beneficial to hindering the accidental rotation of the pouring container bag 3 and avoiding the accidental increase in the rotation amplitude of the pouring container bag 3, resulting in excess molten iron overflowing from the pouring container bag 3 and causing waste; after the molten iron stops pouring out, the rotary drive assembly is closed and the pouring container bag 3 stops pouring. At this time, under the action of the mutual meshing of the secondary reduction worm 7 and the tertiary reduction turbine 6, the self-locking of the pouring container bag 3 is completed, thereby ensuring that the pouring container bag 3 remains stable during the movement, avoiding the molten iron overflowing from the pouring container bag 3 and avoiding the waste of molten iron.
