Description

Technical Field

[0001] This utility model relates to the technical field of ring rolling devices, and in particular to a hot-forged large ring rolling device. Background Technology

[0002] A hot-forging large ring rolling device involves several aspects of existing technology, including the type of ring rolling mill, mold installation issues during processing, and the processing requirements of ring parts. A ring rolling mill is a device used to process workpieces with through holes. Depending on the frame type and the position of the ring part, it can be divided into vertical and horizontal ring rolling mills. For ease of operation, inclined vertical ring rolling mills have also emerged. These different types of ring rolling mills each have their advantages in processing different types and sizes of ring parts. The processing demand for ring parts is large and diverse, thus requiring frequent mold changes during processing. However, traditional mold changing methods rely on naked-eye observation for positioning or measurement with simple tools. This method makes it difficult to guarantee the accuracy and consistency of mold position, thus affecting the quality of the ring parts. During ring processing, heating and forging are crucial steps in improving the toughness of the ring parts. Through continuous hammering, the toughness and other properties of the ring parts can be significantly improved. Therefore, in the design of the hot-forging large ring rolling device, the heating and forging processes are given special attention.

[0003] In existing ring processing technologies, there are various types of ring rolling mills, such as vertical, horizontal, and inclined vertical mills. However, these devices still have some limitations in mold installation, adjustment, and processing. The distance between the processing parts on most existing devices is not adjustable, they cannot be moved, and their adaptability is poor, affecting processing efficiency and quality. Therefore, we propose a hot forging type large ring rolling device to solve this problem. Utility Model Content

[0004] The purpose of this invention is to provide a hot-forging large ring rolling device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A hot-forging type large ring rolling device includes: a reinforced frame, a sliding frame slidably installed inside the reinforced frame, two moving blocks slidably installed inside the sliding frame, a fixed plate fixedly installed on the opposite side of each of the two moving blocks, a sliding block fixedly installed on one side of the fixed plate, a rotating block rotatably installed inside the sliding block, a rolling roller fixedly installed on one side of the rotating block, a motor fixedly installed inside the moving block, a rotating disk fixedly installed at the output end of the motor, a universal joint fixedly installed on one side of the rotating disk, one side of the universal joint being fixedly connected to the rotating block, a rotating block rotatably installed on one side of the sliding frame, a rotating disk fixedly installed on one side of the rotating block, and two connecting rods rotatably installed on one side of the rotating disk, the two connecting rods being rotatably connected to the two moving blocks respectively.

[0007] Preferably, an electric push rod is fixedly installed inside the reinforced frame, and a movable frame is fixedly installed at the output end of the electric push rod.

[0009] Preferably, a motor is fixedly installed on one side of the reinforcement frame, a threaded rod is fixedly installed at the output end of the motor, a threaded block is threadedly connected to the threaded rod, the threaded block is fixedly installed at the bottom end of the sliding frame, and a sliding groove matching the sliding frame and the threaded block is provided on the reinforcement frame.

[0010] Preferably, T-shaped sliders are fixedly installed on both sides of the sliding block, and both sliding blocks are slidably installed in the sliding frame. The sliding frame has sliding grooves that match the sliding blocks and T-shaped sliders.

[0011] Preferably, the mounting block has a mounting groove that matches the small motor, a rotating groove that matches the worm gear, and a rotating groove that matches the worm.

[0012] In this utility model, a hot forging type large ring rolling device is described. By activating an electric push rod fixedly installed in a reinforced frame, the electric push rod drives a movable frame fixedly installed at its output end to move. The movable frame drives a second motor to slide against the core roller, thus moving it away from the support roller. The material that has been heated and preliminarily hot forged is then subjected to strong pressure to form a preliminary ring structure from the metal billet. The preliminarily pressed metal material is placed on the support roller, and the electric push rod drives the movable frame to slide, causing the core roller rotatably installed on the movable frame to abut against one side of the metal material. The second motor fixedly installed at the top of the movable frame is activated, causing the second motor to drive the core roller fixedly installed at its output end to rotate, thereby causing the metal material to rotate. At the same time, the first motor fixedly installed on one side of the reinforced frame is activated, causing the first motor to drive the threaded rod fixedly installed at its output end to rotate. The threaded block connected to the threaded rod is controlled to move, causing the threaded block to drive the sliding frame to move.

[0013] In this utility model, a hot-forging large ring rolling device is described. After the sliding frame is moved to a designated position by the threaded block, two rolling rollers are positioned above and below the metal material, respectively. A small motor fixedly installed in the mounting block is started, which drives the worm gear fixedly installed at its output end to rotate, thereby driving the worm wheel to rotate. The worm wheel drives the rotating block to rotate, which drives the rotating disk to rotate. This causes two connecting rods rotatably installed on one side of the rotating disk to move, and at the same time, it drives two moving blocks to move closer to each other. The movement of the moving blocks drives the sliding block to move through the fixed plate, thereby driving the two rolling rollers to move closer to each other. Two motors are then started, which drive the rotating disk fixedly installed at its output end to rotate, causing the rotating disk to rotate the universal joint, thereby driving the rotating block to rotate, and thus driving the rolling rollers to rotate. This process further rolls and shapes the ring to achieve the required shape and size.

[0014] This utility model has a reasonable structural design. Through the cooperation of multiple structures, the entire structure can be adjusted in position to adapt to the processing requirements of molds and ring parts of different sizes, which significantly improves processing efficiency. It can further adjust and optimize the rolling effect to meet different production needs. Attached Figure Description
