Description

Technical Field

[0001] The utility model belongs to the technical field of auxiliary facilities for steel ball production, and specifically relates to a steel ball shaping device. Background Art

[0002] Mining steel balls are used as a medium for grinding and crushing materials in industries such as mining and cement. They are typically made of hard materials such as steel, ceramic, or silicon carbide, which can withstand the friction and wear during the grinding process. They are primarily used in ball mills.

[0003] In the production process of mining steel balls, shaping of steel balls is an indispensable step. Commonly used equipment, such as a steel ball shaping device disclosed in the Chinese patent document CN208758919U, includes a power transmission mechanism; a base, which is arranged on the left side of the power transmission mechanism; a fixed disk shaft supporting mechanism, which is arranged at the left end of the base; a fixed disk shaft, which is supported on the fixed disk shaft supporting mechanism and has a fixed disk at the right end, and a steel ball outlet is provided on the fixed disk; a rotary disk shaft supporting mechanism, which is arranged at the left end of the base The right end; the turntable shaft is supported on the turntable shaft supporting mechanism and has a turntable on the left end; the fixed shaping ring is fixed on the right side of the fixed plate, and has a fixed shaping ring steel ball rolling groove on its right side surface, a steel ball introduction cavity to be shaped and a shaping steel ball outlet cavity on the circumferential surface, the right side of the shaping steel ball outlet cavity is the shaping steel ball introduction port, and the left side is the shaping steel ball outlet; the rotary shaping ring is fixed on the left side of the turntable and has a rotary shaping ring steel ball rolling groove on the left side surface; the power transmission mechanism is connected to the right end of the turntable shaft.

[0004] When using the above-mentioned shaping device, since it uses a fixed disk and a rotating disk arranged relative to each other to form a chamber for the steel balls to roll, errors are prone to accumulate during the installation and manufacturing process, making it difficult to ensure the concentricity of the two disks, thereby causing eccentricity. Moreover, after long-term use, the shaft and bearings may wear or loosen, which can also cause eccentricity. This can easily lead to uneven force on the steel balls during the shaping process, affecting the operation of the equipment. Therefore, a new steel ball shaping device is needed to address this problem. Utility Model Content

[0005] In order to improve the above problems, the utility model provides a steel ball shaping device, and the specific technical solution is as follows:

[0006] A steel ball shaping device includes a core shaft, a fixed disk and a rotating disk are coaxially provided on the core shaft, the rotating disk is movably connected to the core shaft, and a transmission member is provided on the rotating disk, the transmission member is used to drive the rotating disk to rotate around the core shaft;

[0007] The fixed disk is provided with a rolling groove, the rotating disk is provided with a rolling groove, the rolling groove and the rolling groove constitute a shaping cavity, the fixed disk is provided with a feed port and a discharge port respectively, the fixed disk is provided with a cavity partition block, and the cavity partition block is located between the feed port and the discharge port.

[0008] During the processing, the steel balls to be shaped, which are still in a high-temperature state and rolled in the previous process, are introduced into the shaping cavity. The transmission parts drive the rotating disk to rotate around the core shaft, so that the steel balls to be shaped can be shaped, and the steel balls that have completed shaping are led out of the shaping cavity to the discharge port, thereby realizing the shaping of the steel balls.

[0009] Because both the rotating and fixed disks are mounted on the core shaft, axial coaxiality is ensured, reducing eccentricity caused by installation errors or prolonged use. This also ensures a more stable relative position between the fixed and rotating disks, reducing the risk of eccentricity due to vibration or other external forces. This prevents deformation of the shaping cavity due to eccentricity, which could affect equipment operation.

[0010] Since steel balls come in different sizes, if a larger steel ball enters the shaping cavity, the size of the shaping cavity is fixed, causing the steel ball to easily get stuck in the shaping cavity. Therefore, the fixed disk is slidingly arranged on the core shaft, and a sleeve is provided on the side of the fixed disk away from the rotating disk, and the sleeve slides along the core shaft; a first buffer spring and a second buffer spring are coaxially arranged on the core shaft, and one side of the sleeve conflicts with the first buffer spring. A first fastener is provided on the side of the first buffer spring away from the sleeve, and the side of the fixed disk away from the sleeve conflicts with the second buffer spring. By providing buffer springs at both ends of the fixed disk and the sleeve, when encountering a steel ball with serious size deviation, the fixed disk is easily subjected to a large axial force. At this time, the buffer springs buffer the axial force to avoid excessive wear of the shaping cavity. Moreover, after the fixed disk is squeezed, the buffer spring at the fixed disk can reset the fixed disk in time, thereby improving the flexibility of the fixed disk.

[0011] A rotating sleeve is provided on the side of the rotating disk away from the fixed disk; the transmission member includes a pulley provided on the rotating sleeve. The pulley is driven to rotate by a motor and a belt, thereby driving the rotating disk to rotate, thereby shaping the steel balls to be shaped.

[0012] Because the fixed ring and the rotating ring perform long-term shaping of the steel ball, their shaping cavities are prone to deformation. Therefore, the rotating disk includes a rotating disk and a rotating ring. The rotating disk is connected to the rotating sleeve, and the rotating ring is detachably connected to the rotating disk. The rolling groove is provided on the rotating ring. The fixed disk includes a connecting disk and a fixed ring. The fixed ring is detachably connected to the connecting disk, and the connecting disk is connected to the sleeve. The second buffer spring abuts against the end surface of the connecting disk. The rolling groove is provided on the side wall of the fixed ring. The discharge port includes a connecting port and a discharge port that are interconnected. The connecting port is provided on the bottom wall of the rolling groove, and the discharge port is provided on the connecting disk. The connecting port is provided in communication with the discharge port.

[0013] The fixing ring and the connecting disk, the rotating ring and the rotating disk are detachably arranged, so that the fixing ring can be replaced.

[0014] During installation, since the discharge port and the connecting port need to be aligned, positioning grooves are provided on the opposite side walls of the connecting disk and the fixing ring. The two positioning grooves are arranged opposite to each other, and a positioning block is inserted into the two positioning grooves. The positioning block is detachably connected to the fixing ring or the connecting disk; the positioning block is inserted into the two positioning grooves and fixedly installed, which makes it easy to align the discharge port and the connecting port.

[0015] On the side of the pulley away from the rotating disk, a retaining ring is coaxially provided on the rotating sleeve, and a threaded ring is threadedly connected to the rotating sleeve. In order to fix the pulley, the pulley is limited by the retaining ring and the threaded ring is tightened to fix the pulley.

[0016] The turntable and core shaft are connected by a first bearing. At the rear end of the rotating sleeve, the rotating sleeve and core shaft are connected by a second bearing. A second fastener is provided on the side of the second bearing facing away from the turntable. Both ends of the core shaft are mounted to the frame via support blocks. The core shaft is mounted via the support blocks, and the turntable and rotating sleeve are then mounted via bearings, allowing the turntable and core shaft to rotate on the core shaft.

[0017] Because steel balls with significant dimensional deviations may become stuck when entering the shaping cavity, the groove wall of the rolling groove is recessed with a flaring groove, located near the feed inlet. This flaring groove increases the width of the shaping cavity, making it easier for the steel balls to enter the shaping cavity.

[0018] In order to facilitate the processing of the cavity block, the cavity block is detachably arranged in the rolling groove. The cavity block is detachably installed in the rolling groove instead of the integral molding method, which reduces the processing difficulty.

[0019] Beneficial technical effects of this utility model:

[0020] 1. The steel balls to be shaped, which are still in a high-temperature state and rolled in the previous process, are introduced into the shaping chamber. The transmission parts drive the rotating disk to rotate around the core shaft, so that the steel balls to be shaped can be shaped, and the shaped steel balls are led out of the shaping chamber to the discharge port, thereby realizing the shaping of the steel balls.

[0021] 2. By coaxially arranging the fixed disk and the rotating disk on the core shaft and ensuring the coaxiality of the two in the axial direction, the eccentricity caused by installation error or long-term use is effectively reduced.

[0022] 3. By setting up a buffer spring mechanism, when encountering a steel ball to be shaped with a large size deviation, the buffer spring can effectively buffer the axial force to avoid excessive wear of the shaping cavity. At the same time, the buffer spring can also reset the fixed disk in time, thereby improving the adaptability and flexibility of the device.

[0023] 4. The expanded groove structure increases the width of the shaping cavity on the feed port side, making it easier for steel balls with large size deviations to enter the shaping cavity, reducing the material jamming phenomenon and improving the shaping efficiency.
