Description

Technical Field

[0001] The invention relates to the technical field of pouring machines, in particular to a gantry-type multi-directional steel dual-purpose rotary pouring pouring machine. Background Art

[0002] As an important part of modern industry, the technical level of the foundry industry directly affects the production efficiency and product quality in many fields such as machinery manufacturing, automobiles, and aerospace. In recent years, with the rapid progress of molding technology and equipment and the significant improvement of productivity, the overall outlook of the foundry industry has undergone profound changes. However, in this process, the development of the pouring casting process has not kept pace, becoming a key bottleneck restricting the further optimization of the casting process.

[0003] The existing pouring casting process has the following shortcomings: 1. Serious waste of molten steel: Traditional pouring casting equipment usually adopts a pouring method within a fixed angle or a limited angle range. This operation mode is difficult to adapt to the needs of complex-shaped castings and can easily lead to overflow or incomplete filling of the cavity during the pouring process. This situation is particularly obvious when dealing with large or complex-structured castings, resulting in a large amount of unnecessary consumption of molten steel.

[0004] 2. High scrap rate: Due to the functional limitations of existing equipment, it is impossible to achieve precise control of key parameters such as pouring speed and direction, which increases the possibility of defects such as pores, slag inclusions, and cold shuts inside the casting, ultimately affecting the quality of the casting and increasing the scrap rate. In addition, when encountering castings of different specifications and materials, traditional equipment has poor adaptability and flexibility, further exacerbating this problem.

[0005] 3. Burn and scald accidents occur frequently: In the traditional pouring process, the degree of manual participation is high, especially when working in a high-temperature environment. Once an accidental leak or splash occurs, it is very easy to cause serious burns and scalds. According to relevant statistical data, such accidents not only cause great physical harm to workers, but also bring additional cost burdens to enterprises. For example, it is common for the refractory layer of the medium-frequency furnace to be partially burned through, resulting in molten steel leakage. If the leakage hole increases during the tilting process, it may cause an on-site explosion accident.

[0006] 4. Poor security: The lack of effective protective measures and technical means to ensure the safety of operators makes the risk factor of the entire pouring casting process relatively high; the design of traditional equipment often ignores the importance of ergonomics and does not fully consider the comfort and safety of operators, resulting in many safety hazards in actual operations.

[0007] 5. Inefficiency: Traditional pouring machines have a single function and can only perform simple horizontal or vertical pouring actions. For complex structure castings, the mold position needs to be adjusted frequently, which greatly reduces production efficiency. In addition, manual operation is prone to human errors, further affecting the continuity and stability of production. Summary of the invention

[0030] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0031] Figure 1 The front view of a gantry type multi-directional dual-purpose steel rotary pouring machine provided by an exemplary embodiment of the present invention is shown. The gantry type multi-directional dual-purpose steel rotary pouring machine comprises: a longitudinal transfer vehicle 1, a lifting mechanism 2, a transverse transfer vehicle 3, a rotating mechanism 4, a ladle tilting mechanism 5, and a flow inoculation mechanism 6. The lifting mechanism 2 is liftably connected to the longitudinal transfer vehicle 1; the transverse transfer vehicle 3 is movably connected to the lifting mechanism 2; and the rotating mechanism 4 is installed on the transverse transfer vehicle 3. Figure 1 , Figure 2 and Figure 3 The ladle tilting mechanism 5 is rotatably hung on the rotary mechanism 4 through a hanger 51, and is used to drive the ladle 7 to pour. Figures 1 to 6 The flow-following inoculation mechanism 6 is located above the ladle tilting mechanism 5, and includes a fixed mounting frame 61 mounted on the hanger 51, a horizontal movable frame 62 mounted on the inner side of the fixed mounting frame 61 through a movable assembly 67, a feeder 69 mounted on the top of the horizontal movable frame 62, an inoculation tube lifting frame 63 mounted on the bottom of the horizontal movable frame 62, and an inoculation tube 64 mounted on the inoculation tube lifting frame 63 through a lifting assembly 68. An inoculant hopper 65 is installed at the feeding end of the feeder 69, and a discharge pipe 66 of the feeder 69 can be movably inserted into the inside of the feeding port of the inoculation tube 64, so that the inoculation tube 64 is always in a docking state with the discharge pipe 66 when the inoculation tube 64 is lifted and lowered; wherein, the horizontal movable frame 62 moves along the radial direction of the ladle 7, and when the ladle 7 is in a pouring state, the discharge port of the inoculation tube 64 always moves with the pouring port of the ladle 7, so that the relative position of the discharge port of the inoculation tube 64 and the pouring port of the ladle 7 remains unchanged.

[0032] In the embodiment of the present application, the gantry-type multi-directional dual-purpose steel rotary pouring machine ensures an efficient, accurate and safe pouring process through a series of precisely designed components. The longitudinal transfer vehicle 1, the lifting mechanism 2 and the transverse transfer vehicle 3 work together to provide flexible movement capabilities in three-dimensional space, so that the equipment can be adjusted to the best working position according to actual needs; and the rotary mechanism 4 installed thereon gives the equipment a rotation function, further enhancing the flexibility and adaptability of operation. It is particularly noteworthy that the ladle tilting mechanism 5 is rotatably hung on the rotary mechanism 4 by a hanger 51, which not only allows the ladle 7 to be tilted at different angles to complete the pouring action, but also ensures that the molten iron or steel can flow out smoothly during the pouring process. More importantly, the flow-following inoculation mechanism 6 is cleverly arranged above the ladle tilting mechanism 5, which is supported by a fixed mounting frame 61 and is equipped with a horizontal moving frame 62, a feeder 69, an inoculation tube lifting frame 63 and an inoculation tube 64 with adjustable height and other components. This layout ensures that the inoculant can be accurately fed from the feeder 69 into the flowing molten metal via the discharge pipe 66. Even when the ladle 7 is in a tilted state, the discharge port of the inoculation tube 64 can closely follow the pouring port of the ladle 7, maintaining a relatively fixed positional relationship between the two, thereby avoiding the problem of uneven addition of inoculant due to position offset.

[0033] For further information, see Figures 4 to 6 The moving assembly 67 includes: a first rail 671, a first rack 672, and a first reducer 673. The first rail 671 is installed on the inner side of the fixed mounting frame 61 along the radial direction of the ladle 7, and is movably connected to the horizontal moving frame 62 through a plurality of guide wheels; the first rack 672 is installed on the bottom of the horizontal moving frame 62 along the radial direction of the ladle 7; the first reducer 673 is installed on the fixed mounting frame 61, and the transmission gear on its power output end is meshed with the first rack 672. The lifting assembly 68 includes: a second track 681, an inoculation tube lifting plate 682, a second rack 683, and a second reducer 684. The second track 681 is installed on the inoculation tube lifting frame 63 in a direction perpendicular to the horizontal plane, and is connected to the inoculation tube lifting plate 682 for lifting and lowering through a plurality of sliders; the second rack 683 is installed on the first side of the inoculation tube lifting plate 682 in a direction perpendicular to the horizontal plane; the second reducer 684 is installed on the inoculation tube lifting frame 63, and the transmission gear on its power output end is meshed with the second rack 683; wherein, the inoculation tube 64 is installed on the second side of the inoculation tube lifting plate 682 in a direction perpendicular to the horizontal plane.

[0034] In the embodiment of the present application, the design of the moving assembly 67 and the lifting assembly 68 together ensure that the flow-following inoculation mechanism can accurately and stably perform its functions, providing key support for the addition of inoculant during the pouring process. Specifically, the first track 671 is installed on the inner side of the fixed mounting frame 61 along the radial direction of the ladle 7, and is movably connected to the horizontal moving frame 62 through a plurality of guide wheels, ensuring that the horizontal moving frame 62 can slide smoothly along the predetermined path; and the first rack 672 is installed at the bottom of the horizontal moving frame 62, and meshes with the power output end transmission gear of the first reducer 673 installed on the fixed mounting frame 61, so that the horizontal moving frame 62 can accurately move in the radial direction during the pouring process of the ladle 7. At the same time, the lifting assembly 68 is responsible for controlling the vertical movement of the inoculation tube 64. The second track 681 is installed on the inoculation tube lifting frame 63 in the vertical direction, and is connected to the inoculation tube lifting plate 682 through multiple sliders, allowing the latter to move up and down in the vertical direction; the second rack 683 is also installed on one side of the inoculation tube lifting plate 682 in the vertical direction, and is meshed with the transmission gear at the power output end of the second reducer 684 installed on the inoculation tube lifting frame 63, so as to drive the inoculation tube lifting plate 682 and the inoculation tube 64 thereon to make precise height adjustments. This design not only ensures that the inoculation tube 64 can adjust its height as needed during the pouring process, but also provides higher positioning accuracy and stability due to the use of a gear-rack transmission system, and can maintain good performance even under complex working conditions, thereby ensuring that the discharge port of the inoculation tube 64 always follows the pouring port of the ladle 7, maintaining the relative position of the two unchanged.

[0035] For further information, see Figure 1 The lifting mechanism 2 includes: a third track 21, a total lifting frame 22, a third rack 23, and a third reducer 24. The third track 21 is installed on the longitudinal transfer vehicle 1 in a direction perpendicular to the horizontal plane, and is connected to the total lifting frame 22 for lifting through a plurality of guide wheels; the third rack 23 is installed on one side of the third track 21 in a direction perpendicular to the horizontal plane; the third reducer 24 is installed on the total lifting frame 22, and the transmission gear on its power output end is meshed with the third rack 23; wherein, the transverse transfer vehicle 3 is movably connected to the total lifting frame 22.

[0036] In the embodiment of the present application, the lifting mechanism 2 is designed to provide the entire casting equipment with a height adjustment capability in the vertical direction, ensuring that the casting operation can be carried out smoothly under different height requirements. Specifically, the third track 21 is installed on the longitudinal transfer vehicle 1 in a direction perpendicular to the horizontal plane, and is connected to the main lifting frame 22 through a plurality of guide wheels to achieve a lifting connection, which not only provides a stable guide path, but also reduces friction, ensuring the stability of the main lifting frame 22 during the lifting process. The third rack 23 is also installed on one side of the third track 21 in the vertical direction, and the third reducer 24 is installed on the main lifting frame 22, and the transmission gear on its power output end is meshed with the third rack 23. This gear-rack transmission mode can convert the rotational motion of the motor into linear motion, thereby driving the main lifting frame 22 to move up and down along the third track 21. The traverse vehicle 3 is movably connected to the main lifting frame 22, which means that the traverse vehicle 3 can move laterally on the track provided by the main lifting frame 22. Combined with the vertical height adjustment provided by the lifting mechanism 2, the traverse vehicle 3 can be flexibly positioned in three-dimensional space to adapt to different casting position requirements. In addition, by adjusting the speed and torque of the third reducer 24, the lifting speed of the total lifting frame 22 can be accurately controlled to meet the operating requirements under different working conditions. For example, when rapid positioning is required, the lifting speed can be increased by increasing the motor speed; and when approaching the target position, the speed is reduced to ensure accurate parking. Such a design not only improves work efficiency, but also enhances the flexibility and adaptability of the system, so that the gantry-type multi-directional steel dual-purpose rotary pouring casting machine can maintain efficient and stable operating performance in a complex and changeable working environment.

[0037] It is worth mentioning that the longitudinal transfer vehicle 1 is located on the track of the pouring line and can move long distances along the pouring line through the running wheels, providing the ability to move longitudinally along the fixed track; while the transverse transfer vehicle 3 can move transversely on the transverse track on the main lifting frame 22 through the running wheels (the running wheels are connected to the running wheel reducer for transmission).

[0038] Specifically, see Figure 2 The slewing mechanism 4 includes: a slewing bearing 41, a suspension 42, and a slewing reducer 43. The inner ring of the slewing bearing 41 is fixedly mounted on the bottom of the transverse vehicle 3, and the bottom of its outer gear ring is connected to the suspension 42; the transmission gear on the power output end of the slewing reducer 43 is meshed with the outer gear ring of the slewing bearing 41, and is used to drive the outer gear ring of the slewing bearing 41 to rotate when the slewing reducer 43 is driven by the motor. A weighing sensor 44 is installed on the suspension 42, and the hanger 51 of the ladle tilting mechanism 5 is hung on the weighing sensor 44. Preferably, the number of weighing sensors 44 is four, and they are evenly spaced and distributed on the suspension 42.

[0039] In the embodiment of the present application, the design of the slewing mechanism 4 is intended to realize the rotational movement of the bottom component of the traverse vehicle 3, while accurately controlling the position of the ladle tilting mechanism 5 and monitoring its load in real time. Specifically, the slewing bearing 41 is a key component connecting the traverse vehicle 3 and the suspension 42 below. Its inner ring is fixedly installed at the bottom of the traverse vehicle 3, and the outer gear ring is connected to the suspension 42 through the bottom. When the slewing reducer 43 is driven by a motor, the transmission gear on its power output end meshes with the outer gear ring of the slewing bearing 41, thereby driving the latter to rotate, so that the entire suspension 42 and the ladle tilting mechanism 5 hung thereon can perform a slewing movement around a central axis. In addition, a weighing sensor 44 is installed on the suspension 42. This design allows the hanger 51 of the ladle tilting mechanism 5 to be directly hung on the weighing sensor 44. The weighing sensor 44 not only bears the mass of the hanger 51 and the suspended ladle, but also can convert the mechanical force it feels into an electronic signal for real-time monitoring of the weight of the material in the ladle. This arrangement is essential to ensure the safety and accuracy of the pouring process, as it allows the operator or control system to adjust the pouring parameters according to the actual load, avoiding overloading or underloading. For example, during the casting process, knowing the precise amount of molten iron remaining in the ladle can help the operator better control the pouring speed and amount, thereby improving product quality.

[0040] More specifically, see Figure 3 The ladle tilting mechanism 5 comprises: a tilting frame 52, in which the ladle 7 is placed; one end of the tilting frame 52 close to the pouring port of the ladle 7 is hinged to the hanger 51 through a rotating shaft; and one end of the tilting frame 52 away from the pouring port of the ladle 7 is connected to the hanger 51 through a tilting assembly 53. The tilting assembly 53 comprises: a sector rack 531 and a tilting reducer 532; the sector rack 531 is mounted on the tilting frame 52; the tilting reducer 532 is mounted on the hanger 51, and the transmission gear on the power output end thereof is meshed with the sector rack 531; wherein, when the tilting reducer 532 is driven by a motor, the ladle 7 in the tilting frame 52 is driven to pour.

[0041] In the embodiment of the present application, the ladle tilting mechanism 5 is designed to ensure that the ladle 7 can complete the pouring operation of the molten metal safely and accurately. The tilting frame 52 is the main structural member for supporting the ladle 7. One end of the tilting frame 52 is hinged to the hanger 51 through a rotating shaft, so that the tilting frame 52 can rotate freely at a position close to the pouring port of the ladle 7, and the other end is connected to the hanger 51 through a tilting assembly 53. Such a design not only ensures the stable suspension of the tilting frame 52 in a non-working state, but also provides a mechanical basis for realizing the tilting action of the ladle 7. When the tilting reducer 532 is driven by a motor, it can convert the rotational motion of the motor into the swinging motion of the tilting frame 52, thereby driving the ladle 7 in the tilting frame 52 to pour. This gear-rack transmission method has high transmission efficiency and precision, can ensure the stability and controllability during the pouring process, avoid the risk of molten metal splashing due to sudden start or stop, and improve the safety of operation. In addition, by reasonably designing the speed and torque of the tilting reducer 532, the pouring speed of the ladle 7 can be adjusted according to different process requirements to meet the requirements of various casting processes. For example, in some precision casting processes, it may be necessary to pour the molten metal slowly and evenly to ensure the quality of the casting; while in other scenarios, it may be required to pour quickly to improve production efficiency. Therefore, the ladle tilting mechanism 5 is not only a key device for realizing the pouring of molten metal, but also an important part to ensure the smooth progress of the entire casting process.

[0042] As a supplementary explanation, the feeder 69 is a screw feeder to ensure that the inoculant can be added to the pouring flow evenly and stably. The core component of the screw feeder is a rotating screw shaft located in a closed tubular structure. When the screw shaft rotates, it pushes the inoculant introduced by the inoculant hopper 65 along the direction of the spiral blade until it reaches the discharge pipe 66 and enters the pouring flow through the inoculant pipe 64 softly connected to the discharge pipe 66. In order to achieve precise control of the amount of inoculant, the screw feeder is usually equipped with a variable frequency motor to drive the screw shaft, so that the speed can be adjusted as needed, thereby controlling the amount of inoculant delivered per unit time.

[0043] It is worth mentioning that all the reducers in this application are driven by motors.

[0044] Next, the working principle of a gantry-type multi-directional steel dual-purpose rotary pouring casting machine involved in an embodiment of the present invention is described.

[0045] First, the longitudinal transfer vehicle 1 moves along the predetermined track to the vicinity of the pouring position. It moves along the pouring line for a long distance through the running wheels, providing the longitudinal movement capability along the fixed track for subsequent operations. Secondly, the lifting mechanism 2 installed on the longitudinal transfer vehicle 1 is started, and the third rack 23 is driven by the third reducer 24, so that the main lifting frame 22 moves up and down along the third track 21 to adjust the height of the transverse transfer vehicle 3 to a suitable position. This step ensures that the casting equipment can operate smoothly under different height requirements; Subsequently, the traverse vehicle 3 moves on the lateral track provided by the main lifting frame 22 to achieve accurate horizontal positioning of the pouring point. This process is completed by the transmission connection between the travel wheel and the travel wheel reducer, which provides the necessary lateral displacement capacity; Next, when the transverse transfer vehicle 3 reaches the designated position, the slewing mechanism 4 installed thereon starts to work, and the slewing reducer 43 drives the outer gear ring of the slewing support 41 to rotate, so that the ladle tilting mechanism 5 suspended on the weighing sensor 44 can perform the required slewing motion around the central axis. At the same time, the weighing sensor 44 monitors the weight of the material in the ladle 7 in real time to ensure the safety and accuracy of the pouring process; Then, the ladle tilting mechanism 5 performs the key operation of pouring the molten metal. The tilting reducer 532 drives the sector rack 531, so that the tilting frame 52 drives the ladle 7 to tilt according to the preset angle, thereby starting to pour the molten iron or steel steadily. During this process, one end of the tilting frame 52 is hinged to the hanger 51 through the rotating shaft, and the other end is connected to the hanger 51 through the tilting assembly 53, ensuring the stability and controllability of the entire action. Finally, while the ladle 7 is being poured, the flow-following inoculation mechanism 6 located above it is started, and the feeder 69 feeds the inoculant from the inoculant hopper 65 into the discharge pipe 66 evenly and stably, and accurately adds the inoculant to the flowing molten metal through the inoculant pipe 64 which is always docked with the discharge pipe 66. In order to adapt to the different inclination angles of the ladle 7, the horizontal movable frame 62 moves along the radial direction of the ladle 7, and the inoculant pipe 64 is finely adjusted in the vertical direction through the lifting assembly 68 to ensure that the discharge port of the inoculant pipe 64 always follows the pouring port of the ladle 7, maintaining the relative position between the two unchanged.

[0046] In summary, the gantry-type multi-directional dual-purpose steel rotary pouring pouring machine is exquisitely designed and integrates multiple functions to ensure efficient, safe and flexible pouring operations. It is mainly composed of a lifting mechanism, a transverse moving car, a rotating mechanism, a ladle tilting mechanism and a flow-following inoculation mechanism. The lifting mechanism is connected to the longitudinal moving car to realize vertical movement; the transverse moving car is responsible for horizontal displacement, and the rotating mechanism is installed on the transverse moving car to support the rotation of the ladle tilting mechanism. In particular, the flow-following inoculation mechanism is located above the ladle tilting mechanism, including a fixed mounting frame, a horizontal moving frame, a feeder, an inoculation tube lifting frame and a liftable inoculation tube; an inoculant hopper is provided on the top of the feeder, and the feed pipe is connected to the inoculation tube feed port, which can be connected even when the inoculation tube is raised and lowered; the horizontal moving frame moves along the radial direction of the ladle to ensure that the inoculation tube discharge port can move synchronously with the ladle pouring port, maintain the relative position of the two unchanged, and avoid the problems of inaccurate pouring of molten iron or steel and deviation in inoculant distribution. In addition, the equipment allows the ladle to rotate horizontally, so that it can serve two pouring conveyor lines arranged face to face, realizing multi-point and multi-directional safe and efficient pouring operations. This design not only improves work efficiency, but also enhances operational flexibility and adapts to casting needs in different scenarios.
