Description

Technical Field

[0001] The present invention belongs to the technical field of casting processing, and specifically relates to a carefully designed and improved leaky bottom pouring ladle and its auxiliary casting system and use method, aiming to improve the efficiency, accuracy and safety of casting operations. Background Art

[0002] In the field of traditional casting processing, casting of small and medium batches of multiple varieties of castings has always been full of problems. Take the traditional leaky bottom ladle as an example. The opening and closing of its plug is completely dependent on pure manual control, which means that a lot of manpower is consumed, and the operator has to work close to the high-temperature ladle, and the risk of safety accidents such as burns is extremely high. Moreover, in the casting positioning link, accuracy and efficiency are seriously lacking. Most of the time, the operator relies on experience and rough estimates to align the ladle spout and the casting spout cup. The casting accuracy is not guaranteed, the scrap rate remains high, and repeated adjustments consume a lot of time, which greatly reduces production efficiency. In addition, the existing casting equipment has poor versatility and is difficult to cope with the diverse demands of castings of different specifications and varieties. Every time a casting is replaced, the equipment must be either adjusted significantly or rearranged. The production cost and time cost are rising, which greatly restricts the pace of the foundry industry.

[0003] Manual casting also has many problems. The operator has to go to the casting line in person. He must not only accurately place the ladle at the predetermined location, but also ensure that the bottom of the ladle and the casting pouring cup are accurately aligned. The efficiency bottleneck is very significant. The high temperature environment and direct operation of liquid metal are not only inefficient, but also greatly threaten the safety of operators, and the risk factor of the operation soars. Compared with automated production, manual operation is far less efficient, 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 complicated, and the production cost also rises accordingly. Faced with the increasing demand for small-batch and diversified casting production in the market, traditional automatic systems simply cannot cope with it. Therefore, most manufacturers have no choice but to choose manual casting, especially when dealing with casting operations that require leaky bottom ladles.

[0004] For example, the ladle auxiliary casting device for castings shown in the Chinese patent with publication number CN220462210U has a bag for hanging the ladle, rockers on both sides, rockers connected to cross arms, baffles and handles at the ends of the cross arms, and a series of supporting structures. Its advantage is that the operator can stay away from the ladle during work, ensuring the safety of casting. It is suitable for manual casting of small parts, but the degree of automation is low, and the simple structure is difficult to adapt to large-scale industrial production.

[0005] Let's look at the auxiliary casting device for casting processing disclosed in the Chinese patent with publication number CN220760995U, which includes support beams, connecting frames, electric push rods and other components. With the help of electric push rods and adjustment racks, it can realize automatic bag flipping and reduce labor costs. Unfortunately, it has a low level of automation and poor industrial adaptability. When dealing with small batches of multi-variety castings, it has great limitations and prominent cost issues.

[0006] Overall, the current casting of small batches and multiple varieties of castings is in trouble, facing difficult technical problems such as low degree of automation, limited production efficiency and prominent safety hazards.

[0007] It should be particularly emphasized that the above-mentioned background technology disclosure is intended to assist in understanding the concepts and technical solutions of the present invention. In the absence of definite evidence that it has been disclosed on the date of this patent application, it cannot be used to judge the novelty and creativity of the present application. Summary of the invention

[0008] The present invention aims to overcome the many shortcomings of the prior art, and ingeniously create a leaky bottom ladle that can realize both automated intelligent operation and the flexibility of manual operation. At the same time, it is equipped with a high-precision and high-efficiency auxiliary casting system to fully meet the casting needs of small and medium batches and multiple varieties of castings in the casting processing field, and achieve the multiple goals of reducing costs, improving efficiency, and ensuring personnel safety.

[0009] In order to achieve the above technical objectives, the present invention adopts the following technical solutions:

[0010] A leaky bottom ladle and its auxiliary casting system, comprising a leaky bottom ladle and an auxiliary casting system, wherein the leaky bottom ladle comprises a leaky bottom ladle body, earrings for force conduction connection, a pipe clamp adapted to the main rod diameter and one end of which is screwed and fixed to the main rod, a fixed base support platform for stably placing an oil cylinder, and a movable oil cylinder and its control system; the opening and closing of the leaky bottom ladle plug can be electrically controlled by the movable oil cylinder system or manually operated, and the oil cylinder can be taken out and placed on the fixed base support platform, and its upper end is inserted into the pipe clamp to drive the plug to move.

[0011] Furthermore, the fixed base support platform is firmly attached to the leaky bottom ladle body by welding technology, and is provided with a bayonet, the shape and size of which are adapted to the oil cylinder, so as to facilitate the rapid loading and unloading and stable placement of the oil cylinder.

[0012] Furthermore, the pipe clamp is customized according to the diameter of the main rod of the leaky bottom ladle, and one end is tightly locked on the main rod by a screw, fitting tightly with the main rod without any loose gap.

[0013] Furthermore, the earring is welded to the piston end of the oil cylinder, and the welding process ensures that the position and angle of the earring are accurate, so that it can be smoothly and unobstructedly inserted into one end of the pipe clamp.

[0014] Furthermore, the movable oil cylinder is a plunger-type hydraulic high-temperature resistant and explosion-proof oil cylinder, and its operating temperature is greater than 100°C.

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

[0016] Furthermore, the auxiliary casting system comprises a first traveling mechanism, a second traveling mechanism, a lifting platform and an infrared auxiliary positioning system;

[0017] The first crane mechanism is located directly above the casting pit, and is stably supported on the track beam of the second crane mechanism frame through the designed first wheel system, and can move smoothly along the X-axis direction. It is equipped with a lifting platform mechanism for bearing the leaky bottom ladle and an electric control switch device, and an electric hoist group and a guide wheel group are symmetrically arranged on its upper end and both sides; the electric hoist is selected from high-strength and large-load models and is firmly fixed on the frame of the second crane mechanism. One end of the 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 is running, the lifting platform is driven by the wire rope to move up and down smoothly and vertically, and the guide wheel group moves in a directional manner in the matching guide groove. The leaky bottom ladle is placed on the base of the lifting platform mechanism, and the X-axis infrared control system is installed on the first crane mechanism, and is installed on the slide line through a special pulley. It is driven by a small motor to capture the position information of the leaky bottom ladle plug in the X-axis direction;

[0018] The second crane mechanism includes a solid body and support frame, an efficient crane drive system and an intelligent control system. It is a gantry device that spans the casting pit and can move along the Y-axis direction. Its load-bearing track is in the form of a slide rail, which is deeply anchored to the cement floor on both sides of the casting pit through anchor screws; the wheel system is driven by a motor, and the moving distance is tailored 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 on it, installed on the slide line through a pulley, driven by a small motor, and works in conjunction with the X-axis infrared control system;

[0019] The infrared auxiliary positioning system consists of a pulley, a smooth sliding wire and an infrared transmitting device. The transmitting distance of the infrared device is determined according to the length and width of the casting pit. The transmitting device is installed on the pulley block, the pulley block is installed on the sliding wire, and the sliding wire is fixed on the two ends of the traveling mechanism. By emitting infrared beams, the casting ladle gate and the casting gate cup position are located, and the first traveling mechanism and the second traveling mechanism are cooperated to jointly determine the final casting position of the leaky bottom ladle.

[0020] Furthermore, the crane mechanism body and the lifting platform of the first crane mechanism are welded from channel steels that meet the process requirements, and the channel steel model is selected based on the total weight G of the casting system and a safety factor of 2.

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

[0022] Furthermore, the crane body of the second crane mechanism is made of channel steel and I-beam selected according to the design process requirements, the load capacity and the drive system are determined according to the total weight G of the casting system, and a safety factor of 2 is taken.

[0023] The present invention also provides a method for using a leaky bottom ladle and an auxiliary casting system thereof, comprising the following steps:

[0024] (1) Preparation stage: After placing the leaky bottom ladle on the lifting platform, place the handheld oil cylinder on the oil cylinder support platform to ensure that the oil cylinder is placed stably, and then put the pipe clamp into the upper end of the oil cylinder to complete the preliminary connection between the leaky bottom ladle and the auxiliary casting system;

[0025] (2) Positioning stage: Turn on the X-axis infrared positioning device, move the X-axis infrared device by operating the control panel 15, and observe the display screen to align it with the X-axis center of the leaky bottom ladle plug, and control the error within a certain range;

[0026] Then turn on the Y-axis infrared positioning device, and also move the Y-axis infrared device to align with the Y-axis center of the leaky bottom ladle plug. At this time, the infrared rays form a clear intersection O at the plug, which is the key reference point for casting;

[0027] Finally, by operating the remote control panel of the first crane mechanism and the remote control panel of the second crane mechanism, move the crane mechanism one and the crane mechanism two, keep your eyes on the intersection point O of the infrared rays and the center of the pouring cup of the casting to be cast, and make continuous fine adjustments until the two are completely aligned to complete the positioning;

[0028] (3) Casting stage: After positioning is completed, the bottom-leaking ladle plug is opened through an electric control switch device or manual operation. The molten steel flows into the casting pouring cup under the action of gravity and the casting process begins. During the casting process, the height of the bottom-leaking ladle is adjusted in time through the lifting platform to ensure smooth casting until the casting task is completed.

[0029] Technical principle of the present invention:

[0030] 1. Leaky bottom ladle part:

[0031] The movable cylinder serves as the power core and works based on the hydraulic principle. When the hydraulic oil in the cylinder enters and exits the cylinder chamber according to the preset pressure and flow rules driven by the control system, the piston will produce linear displacement. Since the earring is rigidly connected to the piston, and the pipe clamp is firmly connected to the main rod of the leaky bottom ladle, the displacement of the piston is transmitted to the plug through the earring and the pipe clamp, thereby realizing the opening and closing of the plug. In the electric control mode, the operator sends instructions to the control system through the control button to accurately control the flow direction and flow rate of the hydraulic oil, and then accurately control the action of the plug; in the manual mode, the piston can be manually driven directly through the mechanical structure to realize the operation under emergency or special working conditions. The two modes are compatible through the cleverly designed mechanical and hydraulic oil circuit switching structure.

[0032] 2. Auxiliary casting system:

[0033] The movement of the first and second traveling mechanisms is based on the rotation of the wheels driven by the motor. The friction between the wheels and the track overcomes the inertia and load resistance to achieve precise displacement along the X-axis and Y-axis directions. The lifting platform on the traveling mechanism utilizes the winding characteristics of the electric hoist. When the electric hoist motor rotates, it drives the wire rope to be retracted and released. The wire rope pulls the guide wheel group, and the guide wheel group guides the lifting platform to overcome gravity to achieve vertical movement up and down to meet the casting requirements at different heights. The infrared assisted positioning system utilizes the linear propagation characteristics of infrared rays. The transmitting device emits an infrared beam of a specific wavelength. The transmission angle and position are adjusted through the pulley and wire structure. The infrared rays are irradiated to the ladle gate and the casting gate cup. The reflected light is captured by the receiving device. According to the strength of the light signal and the angle change, combined with algorithms such as triangulation, the relative position deviation of the ladle and the gate cup is accurately calculated and fed back to the control system to drive the traveling mechanism for fine adjustment to achieve high-precision positioning.

[0034] Compared with the prior art, the leaky bottom ladle and its auxiliary casting system of the present invention have the following technical advantages:

[0035] 1. Labor cost: The automated bottom-leaking ladle operation is combined with an efficient auxiliary casting system, which greatly reduces the manual operation process. Operators only need to monitor the operation of the equipment from a safe distance and occasionally intervene in a small amount of necessary operations. Compared with traditional methods, the manpower input is significantly reduced, effectively saving labor costs.

[0036] 2. Production technology cost: The present invention exhibits excellent versatility, the manual and electric dual modes of the leaky bottom pouring ladle, and the adaptive ability of the auxiliary casting system to castings of different specifications greatly reduce the cost consumption caused by frequent equipment replacement and process adjustment, and reduce production technology costs.

[0037] 3. Casting efficiency: The precise infrared auxiliary positioning system and the flexible driving mechanism work in perfect harmony, which can accurately lock the casting site in a short time, greatly reducing the preparation time and adjustment times before casting, significantly increasing the casting volume per unit time, and dramatically improving the casting work efficiency.

[0038] 4. Safety assurance: Operators stay away from the core area of ​​the high-temperature ladle to completely avoid the risk of scalding. At the same time, the stable and reliable operation mechanism of the equipment reduces the probability of operating errors, reduces the risk factor of casting operations from multiple dimensions, and effectively ensures the personal safety of operators.
