Description

Technical Field

[0001] The invention relates to a spinning device, in particular to a head spinning machine suitable for complex curved surfaces. Background Art

[0002] As industrial technology continues to develop, the head, as the core component of the pressure vessel, occupies a pivotal position in the manufacturing industry. In the petroleum, chemical, food and other industries, the role of the head is particularly prominent. They bear the test of pressure, temperature and various media, and are an important link to ensure the safety of the container and the smooth process. Therefore, the manufacturing process of the head directly affects the quality and performance of the pressure vessel, and then it is related to the safety and efficiency of the entire industrial production. The innovation and progress of the head manufacturing technology has always been the focus of the industry.

[0003] Spinning technology is an important part of modern advanced manufacturing technology. Spinning is a processing method that uses a spinning forming machine or a lathe specially designed for spinning to gradually deform the blank material into the required workpiece shape by relying on the main core mold and forming tool. This technology is often used to make round or symmetrical parts, such as car wheels, pots, etc. Spinning technology can achieve high-precision and high-efficiency production and is widely used in the field of metal processing. Therefore, spinning technology is gradually becoming a new favorite in the field of head manufacturing with its unique processing principles and significant advantages. The main defects of spinning equipment: poor equipment flexibility, the spinning wheel and the mold grinding fixed track movement, it is difficult to process different workpieces; poor processing accuracy, the angle of the spinning wheel and the mold cannot be adjusted, and it cannot meet the processing requirements of various positions of the blank; the plate is cold-spun, the rebound is large, and it is difficult to reach the target size; the plate is hot-spun, the whole blank is heated, the cooling is too fast, and the blank stress is uneven. Traditional spinning machine custom molds require a lot of time and capital investment, especially for small-batch production companies, the cost may be unacceptable, and once a specific mold is selected, it is difficult to change the product design and size, limiting the flexibility and diversity of production. At the same time, long-term use will cause mold wear or damage, requiring regular replacement or repair, increasing maintenance costs and time. Summary of the invention

[0004] In order to solve the problem of deformation resistance of materials during processing, the present invention proposes a head spinning machine suitable for complex curved surfaces.

[0005] The present invention is implemented by the following technical solutions:

[0009] In the lower roller system of the spinning equipment, the roller is matched with the hydraulic motor and can rotate freely. The spinning motor is fixed on the slider and can slide on the guide rail with the slider. The slider is installed on the guide rail, the guide rail is installed on the guide rail support plate at the rear, and the hydraulic cylinder is connected to the slider by connecting flange. In the horizontal transmission device, the slider is installed on the guide rail, and the hydraulic cylinder is connected to the slider by connecting flange.

[0012] Since the material itself has deformation resistance problems during the processing, the present invention adds an induction heater, which can heat and spin at the same time to perform warm processing on the material. During warm processing, the ductility of the metal is enhanced and the deformation resistance is reduced, making the forming process easier and able to form more complex parts. Furthermore, the present invention uses a double spinning wheel instead of a mold, and changes the processing effect by setting the feed of the spinning wheel and adjusting the pressure and speed, so that a variety of products can be processed, greatly improving the processing capacity of the spinning machine.

[0025] Figure 1 It is a schematic diagram of the overall structure of the spinning equipment, which mainly consists of four parts, including 1 tail top system, 2 upper spinning wheel system, 3 lower spinning wheel system, 4 main shaft and induction heater system.

[0026] Figure 2It is a tail top device of the spinning equipment. It consists of a connecting flange 2-1, a hydraulic cylinder 2-2, a piston rod 2-3, and a tail top 2-4. The hydraulic cylinder 2-2 is connected to the bed by a middle flange connection. The end of the piston rod 2-3 is installed with a lower connecting flange and a tail top 2-4 to separate the bottom flange movement from the tail top device, so that the tail top can not only clamp the workpiece, but also drive the workpiece and the flange to rotate synchronously under the rotation of the main shaft.

[0027] Figure 3 It is an upper spinning wheel system, including a horizontal transmission device, a vertical transmission device and a spinning wheel. The horizontal transmission device is mainly composed of a slider 3-1, a guide rail 3-2, a hydraulic cylinder 3-3, and a connecting flange 3-4. The hydraulic cylinder 3-3 is fixed to the bed through the connecting flange 3-4 and realizes the horizontal movement of the device on the guide rail 3-2 by pushing the slider 3-1. The vertical transmission system is similar to the horizontal transmission system, mainly composed of a hydraulic cylinder 3-5, a guide rail 3-6, and a slider 3-7. The spinning wheel 3-8 is powered by a hydraulic motor 3-9 to realize the spinning process.

[0028] Figure 4 The lower rotary wheel system includes a rotary wheel, a vertical transmission system and a horizontal transmission system. The rotary wheel 4-1 can perform the spinning process under the drive of the hydraulic motor 4-2. The vertical transmission system is mainly composed of a slider 4-3, a guide rail 4-4, and a hydraulic cylinder 4-5. The hydraulic cylinder 4-5 is a power device, which pushes the slider 4-3 to move on the guide rail 4-4 to realize the vertical movement of the device. The horizontal transmission device is mainly composed of a guide rail 4-6, a hydraulic cylinder 4-8, and a slider 4-8. The hydraulic cylinder 4-7 provides power to drive the slider 4-8 to move on the guide rail 4-6, thereby realizing the horizontal movement of the device.

[0029] Figure 5 It is a spindle and induction heater system. The spindle system mainly includes a spindle turntable 5-1, a spindle shield 5-2, a spindle 5-3, a reducer 5-4, a motor 5-5, and a motor shield 5-6. The motor 5-5 is a power output device. The reducer 5-4 reduces the high-speed input shaft provided by the motor to the required low-speed output shaft speed. The coupling transmits the output rotational motion of the reducer 5-4 to the spindle through a key connection. The induction heater system is mainly composed of a guide rail 5-7, an electric push rod 5-8, a bracket 5-9, and an induction heating head 5-10. The guide rail 5-7 can realize the horizontal movement of the induction heater, and the electric push rod 5-8 can realize the vertical movement of the induction heater. Under the joint action of the guide rail 5-7 and the electric push rod 5-8, the position change of the induction heating head 5-10 can be realized.

[0030] When the spinning machine is working, the processed blank is first placed on the workbench, and fixed by the spindle 5-3 in the spindle shield 5-2. At the same time, the tail top 2-4 can also fix the processed blank. The motor 5-5 provides power, and the high-speed input shaft provided by the motor is reduced to the required low-speed output shaft speed through the reducer 5-4, so as to provide power to the spindle system. The upper and lower spinning wheel systems are driven by the hydraulic cylinder to achieve horizontal and vertical movement. The spinning wheel can realize the swing of the spinning wheel under the drive of the hydraulic motor, and the spinning work of the processed blank is realized under the joint action of the spindle and the spinning wheel. When the processing blank is processed on one side of the spinning wheel, the processing blank is heated by the induction heater 5-10 on the other symmetrical side to reduce the deformation resistance of the material.
