Description

Technical Field

[0001] This utility model relates to the field of metal casting equipment technology, specifically to a high-precision, automated pouring system for a horizontal centrifugal casting machine. Background Technology

[0002] Horizontal centrifugal casting is a widely used forming process for producing blanks of rollers, composite pipes, conveying pipes, and reduction tanks, as well as other roller and pipe sleeve parts. Its core principle lies in pouring molten high-temperature alloy into a high-speed rotating mold, where it fills the cavity and solidifies under strong centrifugal force, resulting in a dense, high-performance casting. In horizontal centrifugal casting, a precise quantity of molten high-temperature alloy must be poured smoothly, accurately, and evenly into the high-speed rotating mold. Traditional pouring methods often rely on manual operation or semi-automated equipment, which suffers from low pouring accuracy, poor stability, and low safety. Improper control of pouring speed, position, and quantity can easily lead to defects such as cold shuts, slag inclusions, and shrinkage cavities in the castings, affecting product quality and posing a safety threat to operators.

[0003] Therefore, there is an urgent need for a pouring system that can achieve precise control, automated operation, and improved safety. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a pouring system for a horizontal centrifugal casting machine. This system can achieve precise control and automated operation of the pouring process, effectively improving the quality of castings and operational safety.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a pouring system for a horizontal centrifugal casting machine, characterized in that it includes: a pouring trolley, a pouring ladle, and a pouring chute; the pouring trolley is driven to move longitudinally on a track by a first driving mechanism; the pouring ladle is hinged to the pouring trolley by a flipping mechanism; the pouring chute is mounted on the pouring trolley by an adjusting frame; it also includes a lateral moving mechanism and a lifting mechanism, the lateral moving mechanism being disposed on the pouring trolley and used to drive the platform carrying the pouring ladle and the pouring chute to move laterally; and the lifting mechanism being used to adjust the height of the pouring chute.

[0006] Preferably, the first drive mechanism includes a servo motor and a planetary reducer, used to drive the casting trolley to move precisely along the track.

[0007] Preferably, the lateral movement mechanism includes a right-angle geared motor and a ball screw.

[0008] Preferably, the lifting mechanism is a screw jack driven by a handwheel, and the front end of the screw jack is provided with a protective baffle.

[0009] Preferably, the tilting mechanism includes a tilting frame driven by a hydraulic cylinder, in which the casting ladle is fitted and can rotate around the tilting axis to an 85-degree tilt angle under the drive of the hydraulic cylinder.

[0010] Preferably, the adjusting frame is a hinged adjusting frame, which makes the angle of the pouring chute adjustable.

[0011] Preferably, the casting trolley is also equipped with an automatic weighing pressure sensor for real-time monitoring of the weight of the molten alloy in the casting ladle.

[0012] Preferably, the inner walls of both the casting ladle and the casting chute are covered with a refractory material protective layer.

[0013] Compared with existing technologies, the beneficial effects of this invention are as follows: Precise multi-degree-of-freedom control: Through the longitudinal, lateral, and lifting movement mechanisms, precise positioning of the end of the pouring chute in three-dimensional space is achieved, ensuring that the molten alloy can be accurately introduced into the optimal position of the mold cylinder. Automation and intelligence: Using servo motor drive and automatic weighing sensors, precise linkage and quantitative control of the pouring trolley's movement and ladle rotation are achieved, reducing human interference and improving pouring stability and consistency. High safety: The protective baffle at the front end of the lifting mechanism effectively prevents high-temperature molten metal splashes from causing injury to personnel and equipment; all actions are completed by mechanical and electrical control systems, eliminating the need for close-range operation by personnel, thus improving safety. Compact structure and strong adaptability: The entire system is integrated on the pouring trolley, with a compact structure. Through adjustment functions in all directions, it can adapt to the process requirements of mold cylinders and castings of different specifications. Attached Figure Description

[0020] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0021] like Figures 1 to 5 As shown, the casting system described in this utility model is a component of a horizontal centrifugal casting machine, and its core function is to precisely pour molten high-temperature alloy liquid into a high-speed rotating mold cylinder.

[0022] The casting trolley 1 is the mobile base of the entire system. It is supported on the track 4 by the wheels at the bottom. The first drive mechanism, namely a 1.5KW servo motor 101 and a planetary reducer 102, drives the casting trolley 1 to move precisely longitudinally along the track 4, with a stroke of 1100mm.

[0023] A lateral movement mechanism is installed on the platform of the casting trolley 1. This mechanism consists of a linear guide rail, a 400W right-angle geared motor 106, and a ball screw 103. This mechanism drives the entire platform (carrying the casting ladle 2 and the casting chute 3) to move laterally to fine-tune the lateral position of the casting.

[0024] The ladle (for casting) is a container for holding molten alloy, its inner wall lined with refractory bricks and refractory mortar. It is hinged to a tilting frame 107 via a support shaft, and the tilting frame 107 is fixed to the trolley platform. A hydraulic cylinder 201 (model number...) As a power source, the tilting frame 107 drives the ladle 2 to rotate around the rotating shaft 108, with a maximum tilt angle of 85°, so that the molten steel is poured smoothly into the casting chute 3.

[0025] The pouring chute 3 serves as a guide channel for the molten alloy, and its inner wall is also lined with refractory clay. It is mounted on the pouring trolley 1 via a hinged adjusting bracket 109, allowing for initial angle adjustment. More importantly, a manual screw jack 104 is mounted on the pouring trolley 1. By rotating a handwheel, a pallet connected to the jack can be raised or lowered, thereby precisely adjusting the inlet and outlet heights of the pouring chute 3. A protective baffle is fixed to the front end of the manual screw jack 104 to prevent any splashing of molten metal. Furthermore, an automatic weighing pressure sensor 105 is integrated into the platform or support structure of the pouring trolley 1 to monitor the weight of the molten alloy in the ladle 2 in real time and, in conjunction with the control system, achieves quantitative pouring.

[0026] Working process: Before pouring, according to process requirements, the outlet of the pouring chute 3 is adjusted to the predetermined pouring position inside the mold cylinder via a horizontal moving mechanism and a lifting mechanism. During pouring, the servo motor 101 drives the pouring trolley 1 to move longitudinally to the mold cylinder opening, while the hydraulic cylinder 201 pushes the pouring ladle 2 to rotate, and molten steel is poured into the mold cylinder through the pouring chute 3. The automatic weighing sensor 105 monitors the pouring volume. After reaching the set value, the hydraulic cylinder 201 retracts to stop pouring, and the trolley returns to its original position. The entire process achieves precise and safe automated pouring.

[0027] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
