Description

TECHNICAL FIELD

[0001] The utility model belongs to the field of casting processing technology, and is exactly related to a casting equipment which is carefully designed and improved, aiming at improving the efficiency, precision and safety of casting operation. BACKGROUND

[0002] In the field of traditional casting processing, the casting of small and medium batch multi-variety castings has always been full of difficulties. Take the traditional bottom pouring ladle, for example. Its plug opening and closing completely relies on manual operation, which means a lot of manpower is consumed, and the operator has to work close to the high-temperature ladle, which has a very high risk of being scalded and other safety accidents. Moreover, in the positioning link of casting, the precision and efficiency are seriously lacking. Most of the time, the operator only relies on experience and rough estimation to align the ladle spout and the casting spout cup, the casting precision is not guaranteed, the scrap rate is high, repeated adjustment consumes a lot of time, and the production efficiency is greatly reduced. In addition, the existing casting equipment has poor versatility, and it is difficult to meet the diversified needs of different specifications and varieties of castings. Every time the castings are replaced, the equipment needs to be adjusted or rearranged, the production cost and time cost are rising, which greatly restricts the pace of the casting industry.

[0003] Manual casting also has many problems. The operator has to go to the casting front line personally, and not only needs to place the ladle accurately at the predetermined position, but also needs to ensure that the bottom of the ladle and the casting spout cup are accurately aligned, and the efficiency bottleneck is very obvious. In a high-temperature environment, the operator's safety is also greatly threatened by directly operating liquid metal, and the operation risk coefficient soars. Compared with automatic production, manual operation is far too inefficient, the production cycle is greatly extended, and the cost also increases. The automatic casting system seems advanced, but it has obvious limitations. The characteristics of being customized for standardized sand boxes and casting sizes make the system architecture complex and the production cost rise. In the face of more and more small batch, diversified casting production needs in the market, the traditional automatic system is simply unable to cope. Therefore, most manufacturers have no choice but to choose manual casting, especially when dealing with casting operations that require bottom pouring ladles.

[0004] The casting iron ladle auxiliary casting device shown in the Chinese patent with publication number CN220462210U has a ladle cover for hanging the iron ladle, two side connecting rocker arms, a rocker arm connecting a horizontal arm, a baffle and a handle provided at the end of the horizontal arm, and a series of supporting structures. Its advantage is that the operator can be away from the iron ladle during work, ensuring the safety of casting, and it is suitable for manual casting of small parts, but the automation degree is low, and the simple structure is difficult to adapt to large-scale industrial production.

[0005] Looking at the auxiliary casting device for casting processing disclosed in Chinese Patent Publication No. CN220760995U, it contains support beams, connecting frames, electric push rods and other components, and can realize self-hanging ladle overturning and reduce labor costs through the cooperation of electric push rods and adjusting racks. Unfortunately, it has low automation level, poor industrial adaptability, and great limitations and cost problems when dealing with small-batch multi-variety casting pouring.

[0006] In summary, the current small-batch multi-variety casting pouring is in a dilemma, facing low automation level, limited production efficiency, and prominent safety hazards.

[0007] It should be particularly emphasized that the above background technology disclosure is intended to assist in understanding the concept and technical solution of the utility model, and cannot be used to judge the novelty and inventiveness of the present application in the absence of exact evidence that it has been disclosed on the filing date of the present patent application. Utility model content

[0008] The utility model aims to overcome the shortcomings of the prior art and create a leaky bottom pouring ladle that can realize automatic intelligent operation and manual operation flexibility. The high-precision and high-efficiency auxiliary casting system provided simultaneously can fully meet the small-batch multi-variety casting pouring needs in the casting processing field, achieving the multiple goals of reducing costs, improving efficiency, and ensuring personnel safety.

[0009] To achieve the above technical purposes, the utility model adopts the following technical solutions:

[0010] A casting equipment includes a leaky bottom pouring ladle and an auxiliary casting system. The leaky bottom pouring ladle includes a leaky bottom pouring ladle body, ear rings for force transmission connection, a pipe clamp that is adapted to the diameter of the main rod and is fixed at one end of the main rod by a screw, a fixed base support platform for stable placement of the oil cylinder, and a movable oil cylinder and its control system. The opening and closing of the leaky bottom pouring ladle plug can be controlled electrically by the control system of the movable oil cylinder, and can also be manually operated. The oil cylinder can be taken out and placed on the fixed base support platform, and its upper end is sleeved into the pipe clamp to drive the plug to move.

[0011] Further, the fixed base support platform is firmly attached to the leaky bottom pouring ladle body by welding process, is provided with a bayonet, and has a shape and size adapted to the oil cylinder, facilitating quick assembly and stable placement of the oil cylinder.

[0012] Further, the pipe clamp is customized according to the diameter of the main rod of the leaky bottom pouring ladle, and is tightly locked at one end of the main rod by a screw, tightly adhering to the main rod without loose gap.

[0013] Further, the ear rings are welded at the piston end of the oil cylinder, and the welding process ensures the precise position and angle of the ear rings, enabling them to be smoothly and unobstructively sleeved into one end of the pipe clamp.

[0014] Further, the movable oil cylinder is a plunger type hydraulic explosion-proof oil cylinder with a working temperature greater than 100℃.

[0015] Further, the oil cylinder piston stroke is selected between 100-200mm according to the volume of the bottomless ladle and the opening requirement of the plug, and the working pressure is 500-1000kg.

[0016] Further, the auxiliary casting system comprises a first travelling crane mechanism, a second travelling crane mechanism, a lifting platform and an infrared auxiliary positioning system.

[0017] The first travelling crane mechanism is located directly above the casting pit and is stably supported on the track beam of the second travelling crane mechanism frame through the designed first travelling crane wheel system, and can move along the X-axis direction. The lifting platform mechanism for supporting the bottomless ladle and the electric control switch device are arranged on the first travelling crane mechanism. The electric hoist group and the guide wheel group are symmetrically arranged on the upper end and both sides of the first travelling crane mechanism. The electric hoist is selected from a high-strength and large-load type and is firmly fixed on the frame of the second travelling crane mechanism. One end of the steel wire rope is tightly wound on the electric hoist, and the other end is firmly fixed on the guide wheel group. The guide wheel group is fixed on the lifting platform as a guide component. When the electric hoist operates, the lifting platform moves up and down stably and vertically through the steel wire rope. The guide wheel group moves directionally in the matched guide groove. The bottomless ladle is placed on the base of the lifting platform mechanism. The X-axis infrared control system is installed on the first travelling crane mechanism, driven by a small motor through a pulley installed on a slide wire, and captures the position information of the X-axis direction of the bottom of the ladle.

[0018] The second travelling crane mechanism comprises a solid body and a support frame, an efficient travelling crane driving system and an intelligent control system, and is a gantry device that can move along the Y-axis direction across the casting pit. The supporting track adopts a slide rail form and is deeply anchored to the cement ground on both sides of the casting pit through foundation screws. The travelling crane wheel system is driven by a motor, and the moving distance is customized according to the Y-axis length of the casting pit, and the width is accurately determined according to the actual width of the casting pit. The Y-axis infrared control system is also installed thereon and driven by a small motor through a pulley installed on a slide wire, and cooperates with the X-axis infrared control system.

[0019] The infrared auxiliary positioning system is composed of a pulley, a smooth slide wire and an infrared emission device. The emission distance of the infrared device is determined according to the length and width of the casting pit. The emission device is installed on the pulley set, the pulley set is installed on the slide wire, and the slide wire is fixed on the both ends of the travelling mechanism. The position of the casting ladle and the casting cup is positioned by emitting infrared beams, and the final casting site of the bottomless ladle is determined together with the first travelling crane mechanism and the second travelling crane mechanism.

[0020] Furthermore, the crane mechanism body and lifting platform of the first crane mechanism are welded from channel steel that meets the process requirements. The channel steel model is selected according to the total weight G of the casting system and the safety factor 2.

[0021] Furthermore, the electric hoist assembly and guide wheel assembly are selected based on the total system weight G, according to a safety factor of 1.5.

[0022] Furthermore, the body of the second traveling mechanism is selected from channel steel and I-beams according to the design process requirements, and the load capacity and drive system are determined based on the total weight G of the casting system, with a safety factor of 2.

[0023] The technical principle of this utility model:

[0024] 1. Bottom-filled pouring ladle section:

[0025] The movable hydraulic cylinder serves as the core power source, operating based on hydraulic principles. When hydraulic oil within the cylinder flows in and out of the cylinder chamber according to preset pressure and flow rates under the control system's guidance, the piston experiences linear displacement. Because the lug is rigidly connected to the piston, and the pipe clamp is securely connected to the main rod of the bottom-pouring ladle, the piston's displacement is transmitted to the plug via the lug and pipe clamp, thus enabling the plug's opening and closing. In electric control mode, the operator sends commands to the control system via control buttons to precisely regulate the flow direction and speed of the hydraulic oil, thereby accurately controlling the plug's movement. In manual mode, the piston can be manually driven directly through the mechanical structure, enabling operation in emergency or special conditions. The two modes are compatible through a cleverly designed mechanical and hydraulic circuit switching structure.

[0026] 2. Auxiliary casting system:

[0027] The movement of the first and second gantry mechanisms is based on the rotation of wheels driven by motors. The friction between the wheels and the rails overcomes inertia and load resistance, achieving precise displacement along the X and Y axes. The lifting platform on the gantry mechanism utilizes the winding characteristics of an electric hoist. When the electric hoist motor rotates, it drives the wire rope to wind and unwind. The wire rope pulls the guide wheel assembly, which guides the lifting platform to overcome gravity and achieve vertical movement, meeting the needs of casting at different heights. The infrared-assisted positioning system utilizes the linear propagation characteristics of infrared light. The transmitting device emits a specific wavelength infrared beam. The emission angle and position are adjusted through a pulley and sliding line structure. The infrared light illuminates the ladle, pouring gate, and casting pouring cup. The reflected light is captured by the receiving device. Based on the intensity and angle changes of the light signal, combined with algorithms such as triangulation, the relative positional deviation between the ladle and pouring cup is accurately calculated and fed back to the control system, driving the gantry mechanism to make fine adjustments and achieve high-precision positioning.

[0028] Compared with existing technologies, the casting equipment of this utility model has the following technical advantages:

[0029] 1. Regarding labor costs: The automated bottom-pouring ladle operation, combined with a highly efficient auxiliary casting system, significantly reduces direct manual operation. Operators only need to monitor the equipment from a safe distance and occasionally intervene in a few necessary operations. Compared to traditional methods, the labor input is significantly reduced, effectively saving labor costs.

[0030] 2. Production technology cost: This utility model demonstrates excellent versatility, with manual and electric dual modes for the bottom-pouring ladle, and the auxiliary casting system's adaptability to castings of different specifications, greatly reducing the cost of frequent equipment changes and process adjustments, and lowering production technology costs.

[0031] 3. Casting efficiency: The precise infrared-assisted positioning system and the flexible crane mechanism work together to accurately lock the casting position in a short time, greatly reducing the preparation time and adjustment times before casting. The amount of castings cast per unit time is significantly increased, and the casting efficiency is improved by leaps and bounds.

[0032] 4. Safety Assurance: Operators are kept away from the core area of ​​the high-temperature ladle, completely avoiding the risk of burns. At the same time, the stable and reliable operation mechanism of the equipment reduces the probability of operational errors, thereby reducing the risk factor of casting operations from multiple dimensions and effectively ensuring the personal safety of operators.

[0042] Please refer to the following appendix Figures 1-8 Non-limiting and non-exclusive embodiments will be described, wherein the same reference numerals denote the same parts unless otherwise specifically stated.

[0043] A casting device includes a bottom-venting ladle and an auxiliary casting system. The bottom-venting ladle is a modified version of an existing bottom-venting ladle, comprising a bottom-venting ladle body 1, an ear ring 2 for force transmission connection, a pipe clamp 3 adapted to the diameter of the main rod and fixed to the main rod at one end by a screw, a fixed base support platform 5 for stabilizing the hydraulic cylinder, and a movable hydraulic cylinder 4 and its control system. The opening and closing of the bottom-venting ladle plug can be electrically controlled by the control system of the movable hydraulic cylinder or manually operated. The hydraulic cylinder 4 can be easily removed and placed on the fixed base support platform, and its upper end can be accurately fitted onto the pipe clamp 3 to drive the plug to move. The basic structure of the modified bottom-venting ladle body 1 remains unchanged, and the original system spare parts are still compatible and usable.

[0044] The fixed base support platform is firmly attached to the bottom pouring ladle body 1 by welding process. It is equipped with specially designed bayonet, the shape and size of which are adapted to the oil cylinder 4, so as to facilitate the quick loading and unloading and stable placement of the oil cylinder 4.

[0045] The pipe clamp 3 is customized according to the precise diameter of the main rod of the bottom-pouring ladle. The material has high strength and high temperature resistance to ensure reliable connection and no deformation in the high temperature environment of casting. One end is tightly locked to the main rod with a high-strength screw, and fits tightly with the main rod without any loose gaps.

[0046] The earring 2 is made of high-temperature resistant alloy material and is welded to the piston end of the oil cylinder. The welding process ensures that the position and angle of the earring 2 are accurate, so that it can be smoothly and unobstructedly fitted into one end of the tube clamp 3 to achieve efficient force transmission and drive the end cap to move.

[0047] The movable hydraulic cylinder 4 is a plunger-type high-temperature resistant explosion-proof hydraulic cylinder with a working temperature greater than 100°C, adapting to the high-temperature heat radiation environment of the casting site; the piston stroke of the cylinder is precisely selected between 100-200 mm according to the volume of the bottom-pouring ladle and the opening requirements of the plug, ensuring smooth and precise opening and closing of the plug; the working pressure is 500-1000 kg, which meets the requirements of driving the plug to overcome the resistance of molten steel gravity, friction and other forces, and to work stably.

[0048] The auxiliary casting system includes a first traveling mechanism 6, a second traveling mechanism 7, a lifting platform 8, and an infrared auxiliary positioning system 9.

[0049] The first gantry crane is located directly above the casting pit 17. It is stably supported on the track 10 beam of the second gantry crane frame by a specially designed first gantry wheel system 11, allowing for smooth and precise movement along the X-axis. It is equipped with a lifting platform mechanism for supporting the bottom-pouring ladle and a sensitive electric control switch device 13. The electric control switch device 13 includes a hydraulic power unit, with electric hoist assemblies 14 and guide wheel assemblies 12 symmetrically and precisely arranged on its upper end and both sides. The electric hoists are high-strength, high-load models, firmly fixed to the frame of the second gantry crane. One end of the wire rope is tightly wound around the electric hoist, and the other end is firmly fixed to the guide wheel assembly. The guide wheel assembly is fixed to the lifting platform as a precision guiding component. When the electric hoist is running, it drives the lifting platform to move up and down smoothly and vertically through the wire rope. The guide wheel assembly moves in a directional manner in the matching guide groove. The bottom-pouring ladle is placed stably on the base of the lifting platform mechanism. The X-axis infrared control system is installed on the first traveling mechanism and cleverly installed on the sliding line through pulleys. Driven by a small motor, it can quickly and accurately capture the position information of the bottom-pouring ladle plug in the X-axis direction.

[0050] The second gantry mechanism comprises a robust body and support frame, an efficient gantry drive system, and an intelligent control system. It is a gantry device that spans the casting pit and can move flexibly along the Y-axis. Its load-bearing rail adopts the form of slide rail 16, which is firmly anchored to the cement ground on both sides of the casting pit with anchor bolts to ensure structural stability and strong load-bearing capacity. The second gantry wheel system 19 is driven by a powerful motor. The movement distance is customized according to the precise length of the Y-axis of the casting pit, and the width is precisely determined according to the actual width of the casting pit to ensure perfect adaptation and smooth operation in various casting scenarios. The Y-axis infrared control system is also precisely installed on it, mounted on the slide line through pulleys, and driven by a small motor. It works in coordination with the X-axis infrared control system for precise operation.

[0051] The infrared-assisted positioning system consists of high-precision pulleys, smooth sliding lines, and a high-sensitivity infrared transmitter. The emission distance of the infrared transmitter is scientifically and accurately determined based on the length and width of the casting pit. The transmitter is mounted on the pulley block and can move flexibly and precisely with the pulley block. The pulley block is mounted on the sliding line, which is fixed at both ends of the traveling mechanism. By emitting infrared beams, the system accurately positions the pouring gate of the casting ladle and the pouring cup 19 on the casting to be poured 18. It works closely with the first and second traveling mechanisms to jointly determine the final pouring point of the bottom-draining ladle, raising the casting accuracy to a new level.

[0052] The crane mechanism body and lifting platform of the first crane mechanism are welded from channel steel that meets specific process requirements. The channel steel model is strictly selected according to the total weight G of the casting system (including the total weight of molten steel, the weight of the lifting platform, the weight of auxiliary equipment such as the bottom pouring ladle) and the safety factor 2 calculated in advance, to ensure that the overall structural strength is sufficient to bear the load under various complex working conditions.

[0053] The electric hoist assembly and guide wheel assembly are carefully selected based on the total system weight G and a safety factor of 1.5 to ensure strong power and stable operation. The specifications and models of each component are compatible with each other, and the installation layout strictly follows the design requirements to ensure that each component is tightly connected and works together efficiently and smoothly.

[0054] The body of the second traveling mechanism is made of channel steel, I-beams and other materials selected according to the precision design process requirements. The material specifications and models are adapted to the load requirements. The load and drive system are determined based on the total weight G of the casting system. A safety factor of 2 is taken to ensure that the gantry structure is stable and flexible in movement, and can adapt to the casting of castings of different specifications.

[0055] The pulleys of the infrared-assisted positioning system are made of low-friction, high-precision materials, and the slide rails have good conductivity and smoothness. The infrared emitting device has a finely adjustable emission angle and stable emission power, ensuring accurate positioning in different environments. The positioning accuracy error is controlled within a very small range, meeting the requirements of high-precision casting.

The clamps are precisely set, and the dimensional tolerance of the clamps is controlled within a very small range to ensure a tight fit with the outer circumference of the hydraulic cylinder. This provides stable support for the hydraulic cylinder and facilitates quick installation and disassembly.

[0060] Pipe clamp fabrication: Based on the measured diameter of the main rod, the material is precisely cut and bent using CNC machining equipment to fabricate the pipe clamp, ensuring that the inner diameter of the pipe clamp and the diameter of the main rod are within a high-precision range. Then, one end of the pipe clamp is firmly locked onto the main rod with high-strength, high-temperature resistant screws to ensure that the connection is stable and does not loosen under high temperature and high load.

[0061] Welding Earrings: Using advanced processes such as argon arc welding, high-temperature alloy earrings are precisely welded to the piston end of the hydraulic cylinder. The position and angle deviation of the earrings are repeatedly checked with high-precision measuring tools to ensure that they can be accurately fitted into one end of the tube clamp, so as to achieve efficient force transmission.

[0062] Hydraulic cylinder selection: Taking into account factors such as the volume of the bottom pouring chamber, the density of molten steel, and the casting frequency, hydraulic cylinders that meet the requirements of working temperature greater than 100℃, piston stroke of 100-200 mm, and working pressure of 500-1000 kg are selected from a large number of plunger-type hydraulic high-temperature explosion-proof cylinder products to ensure that their performance matches the casting conditions.

[0063] 2. Installation and commissioning of the auxiliary casting system:

[0064] First traveling mechanism installation:

[0065] Structural assembly: Based on the total weight G of the casting system, the channel steel model is precisely selected according to the safety factor of 2.

[0067] Infrared system debugging: The X-axis infrared control system is installed on the slide line through a special high-precision pulley. The small motor is debugged and the initial position of the infrared device is precisely calibrated. Through simulation test, it is ensured that it can move quickly and accurately along the X-axis direction, and capture the position information of the bottom pouring plug in the X-axis direction in real time, with the error controlled within a very small range.

[0068] Second traveling mechanism installation:

[0069] Body assembly: According to the design and process requirements, materials such as channel steel and I-beams are selected, and the crane mechanism body is assembled by cutting and welding with the help of precision machining equipment. The load capacity and drive system parameters are determined based on the total weight G of the casting system, and a safety factor of 2 is taken to ensure the stability of the gantry structure.

[0070] Track fixing: The load-bearing track is firmly fixed to the cement ground on both sides of the casting pit with high-precision anchor bolts. The level and parallelism of the track are repeatedly calibrated with a level to ensure that the second traveling wheel system 19 runs smoothly without the risk of deviation or jamming.

[0071] Infrared coordination: The Y-axis infrared control system is precisely installed on the second gantry mechanism using the same pulley and cable method. The motor is debugged and the emission angle and position are finely adjusted to ensure seamless connection with the X-axis infrared control system. This collaborative and precise positioning of the casting position in the Y-axis direction enables all-round precise positioning.

[0072] Installation of infrared-assisted positioning system:

[0073] According to the design layout, the pulley block is installed on the guide line to ensure that the pulleys rotate flexibly and without jamming. Then, the infrared transmitter is steadily installed on the pulley block. The transmission distance of the infrared transmitter is scientifically adjusted according to the length and width of the casting pit to ensure that its coverage area accurately covers the casting area, thereby achieving high-precision positioning of the casting ladle gate and the casting pouring cup.

[0074] 3. Instructions for use:

[0075] Preparation stage: After placing the bottom-drip ladle on the lifting platform, carefully place the hand-held hydraulic cylinder on the hydraulic cylinder support platform to ensure that the hydraulic cylinder is placed stably. Then, precisely insert the upper end of the hydraulic cylinder into the pipe clamp to complete the initial connection between the bottom-drip ladle and the auxiliary casting system.

Using the control panel 15, slowly move the X-axis infrared device and carefully observe the display screen to ensure that it is precisely aligned with the X-axis center of the bottom pouring plug, with the error controlled within a very small range.

[0078] Next, turn on the Y-axis infrared positioning device and carefully move the Y-axis infrared device to precisely align it with the Y-axis center of the bottom pouring ladle plug. At this time, the infrared rays form a clear intersection point O at the plug, which is the key reference point for casting.

[0079] Finally, by operating the remote control panel of the first and second crane mechanisms, the crane mechanism 1 and crane mechanism 2 are moved slowly and precisely. The eyes are focused on the intersection point O of the infrared beams and the center of the pouring cup of the casting to be poured. The adjustments are made continuously until the two are perfectly aligned, thus completing the precise positioning and laying the foundation for high-quality casting.

[0080] Casting stage: After positioning is completed, according to the casting process requirements of the casting, the bottom pouring ladle plug is opened by electric control switch or manual operation (choose according to the situation). Molten steel flows smoothly into the casting pouring cup under the action of gravity, and the casting process begins. During the casting process, the height of the bottom pouring ladle can be adjusted in time by lifting platform to ensure smooth casting until the casting task is completed.
