DETAILED DESCRIPTION

[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0030] In the present application, the cutting assembly may be driven by hydraulic drive, which is a power transmission method based on the principles of fluid mechanics and is widely used in various engineering and mechanical systems.

[0031] 1. Basic Principles

[0032] The basic principle of hydraulic actuation is to apply pressure within a closed system, causing a fluid (usually oil) to generate force and transmit it to an actuator. Specifically, a hydraulic actuation system uses a hydraulic pump to pump fluid into the system and apply pressure. This fluid pressure is converted into corresponding force and motion in an actuator (such as a hydraulic cylinder or hydraulic motor).

[0033] 2. System composition

[0034] A hydraulic drive system usually consists of the following main parts:

[0035] Liquid medium: usually oil, which has the characteristics of low compressibility, strong transmission ability and high working efficiency, and can maintain a relatively stable fluid pressure during the pressure transmission process.

[0036] Hydraulic energy: The power source that drives liquid movement, provided by a hydraulic pump. A hydraulic pump draws liquid into a pump chamber through rotational mechanical motion, and then pushes the liquid out through pressure changes in the pump chamber, creating a certain flow rate and pressure.

[0037] Actuators: Components responsible for performing specific tasks, such as hydraulic cylinders and hydraulic motors. Hydraulic cylinders can push or pull objects, while hydraulic motors can drive rotating devices.

[0038] Control elements: These are used to control the operating state of a hydraulic system. Common control elements include hydraulic valves and hydraulic control valves. Hydraulic valves control the actuators by controlling the direction and volume of fluid flow, ensuring the hydraulic system operates as desired.

[0039] 3. Hydraulic drive has the following advantages:

[0040] High power density: capable of generating greater driving force in a smaller volume.

[0041] High reliability: The hydraulic system has a relatively simple structure, is easy to maintain, and has high reliability.

[0042] Precision: By controlling pressure and flow in the system, precise motion control can be achieved.

[0043] Smooth operation: The hydraulic drive system has low noise and vibration levels and operates smoothly.

[0044] Easy to implement remote control: The operation of the hydraulic system can be remotely controlled via cables or wireless signals.

[0045] 4. Although hydraulic drive has many advantages, it also has some disadvantages:

[0046] Leakage problem: Since the seals in the hydraulic system are prone to wear or aging, fluid leakage may occur, affecting the performance and safety of the system.

[0047] Sensitive to temperature: The performance of hydraulic oil is greatly affected by temperature. Too high or too low temperature may affect the normal operation of the system.

[0048] High maintenance cost: The hydraulic system requires regular replacement of hydraulic oil and cleaning of the system, and the maintenance cost is relatively high.

[0049] Energy loss: During the hydraulic drive process, energy needs to undergo two conversions (from mechanical energy to hydraulic energy, and then from hydraulic energy to mechanical energy), resulting in large system energy loss and low transmission efficiency.

[0050] 5. Application areas

[0051] Hydraulic drives are widely used in many fields, including but not limited to:

[0052] Construction machinery: such as excavators, loaders, cranes, etc., hydraulic drives provide these equipment with powerful driving force and precise motion control.

[0053] Mining machinery: During the mining process, hydraulic drive is used to drive various mining equipment and transportation equipment.

[0054] Paving machinery: such as rollers, pavers, etc., hydraulic drive provides these equipment with smooth movement and precise compaction effect.

[0055] High-end agricultural machinery: such as tractors and harvesters, hydraulic drive improves the operating efficiency and precision of these equipment.

[0056] Marine machinery: In marine engineering, hydraulic drives are used to drive various underwater equipment and mechanical equipment on ships.

[0057] In summary, hydraulic drive is a power transmission method based on the principles of fluid mechanics, which has many advantages and a wide range of applications. However, it also has some disadvantages that need to be paid attention to during use and maintenance.

[0058] The cutting assembly of the present application can also be driven by air pressure, which is a technology that uses gas pressure difference to generate force and movement.

[0059] 1. Basic Principles

[0060] The principle of pneumatic actuators is to use gas pressure differences to generate force and motion. When gas flows from a high-pressure area to a low-pressure area, it generates a thrust that can be used to drive an actuator. By adjusting the pressure difference, the speed and force of the actuator can be controlled.

[0061] 2. System composition

[0062] A pneumatic drive system typically consists of the following components:

[0063] Gas source: Equipment that provides compressed gas, such as air compressors, gas cylinders, etc.

[0064] Gas line: includes gas pipes, joints, valves, etc., used to transport compressed gas to the actuator.

[0065] Actuator: A component that converts the pressure energy of gas into mechanical energy, such as a cylinder, air motor, etc.

[0066] 3. Main Features

[0067] Simple and reliable: The structure of the pneumatic drive system is relatively simple, and the components are easy to process and maintain, so it has high reliability.

[0068] Strong environmental adaptability: The pneumatic drive system can work in harsh environments such as flammable, explosive, dusty, radiation, strong magnetic, vibration, and impact, and has high environmental adaptability.

[0069] The working medium is easy to obtain: air can be obtained directly from the atmosphere, and the used air can also be directly discharged into the atmosphere. The acquisition and treatment of the working medium is very convenient.

[0070] Low maintenance cost: Due to the simple structure of the components of the pneumatic drive system, the maintenance cost is relatively low.

[0071] 4. Main advantages

[0072] Quick action: Pneumatic control is quicker in action and response than hydraulic control, and automatic control of the system can be easily achieved using air pressure signals.

[0073] Low pollution: The working medium of the pneumatic drive system is air, which will not pollute the environment.

[0074] Easy to achieve long-distance transportation: The viscosity of air is very low and the pressure loss in the pipeline is very small, so compressed air is easy to centrally supply and transport over long distances.

[0075] 5. Main Disadvantages

[0076] Poor speed stability: Due to the high compressibility of air, if speed control is performed by adjusting the air flow, the stability of the movement speed will be poor.

[0077] Slow signal transmission speed: The signal transmission speed in pneumatic devices is slower than the speed of electrons and light (limited to the speed of sound), and cannot be applied to complex systems that require very high signal transmission speed.

[0078] 6. Application Areas

[0079] Pneumatic drive technology is widely used in many fields, including but not limited to:

[0080] Industrial Manufacturing: Pneumatically driven robots are widely used in industrial production lines, providing power and control support for various robotic arms, slides, flipping mechanisms, etc. in the production process, thereby improving production efficiency and quality.

[0081] Healthcare: Pneumatic drive technology is also increasingly used in the medical field. For example, it can be used to control robotic surgical instruments to achieve more accurate and effective surgical treatments.

[0082] Human-computer interaction: Pneumatically driven robot technology can also be used to develop various intelligent service robots, such as smart homes and smart customer service, to achieve a more humane and efficient service experience.

[0083] In summary, pneumatic drive technology offers advantages such as simplicity and reliability, strong environmental adaptability, readily available working fluids, and low maintenance costs. However, it also has disadvantages such as poor speed stability and slow signal transmission. When selecting pneumatic drive technology, comprehensive considerations should be made based on the specific application scenario and requirements.

[0084] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific implementation methods.

[0085] Reference Figure 1-Figure 5 As shown, this embodiment provides a steel plate ring forming machine, comprising:

[0086] The frame 1 has a feeding assembly at one end thereof for feeding the steel plate 2;

[0087] The ring forming assembly includes a forming rod 3 rotatably connected to the frame 1, and the steel plate 2 fed by the feeding assembly surrounds the forming rod 3 for forming;

[0088] The external force forming assembly includes two formers 4 symmetrically arranged on both sides of the forming rod 3. The two formers 4 are arranged along the movement direction of the steel plate 2. The formers 4 are telescopically abutted against the outer wall of the forming rod 3 to assist in the ring forming;

[0089] The cutting assembly is telescopically arranged on the frame 1 and is used for cutting the steel plate 2.

[0090] The utility model discloses a steel plate ring forming machine, which is mainly used for automatically processing steel plate 2 rings; a frame 1 fixes the entire equipment in a workshop to ensure the stability of the production process; a strip steel plate 2 of set specifications is fed into the ring forming assembly under the drive of a feeding assembly, and a subsequent ring forming process is carried out, thereby realizing automatic feeding, reducing the process of manual positioning, and improving production efficiency; when the fed steel plate 2 passes through the ring forming assembly, it is surrounded by a forming rod 3, and at the same time, two formers 4 of the external force forming assembly are symmetrically arranged on both sides of the forming rod 3, and their output ends are simultaneously extended and retracted. , against the outer wall of the steel plate 2, so that the steel plate 2 is constrained and squeezed and deformed to form the required circular ring; and when the end of the steel plate 2 is circled for a circle, the cutting assembly is started to cut the steel plate 2, realizing automatic cutting according to the circular ring specifications, reducing the process of cutting materials in advance, and also reducing the generation of waste; the cut steel plate 2 finally forms the required circular ring under the constraint of the forming rod 3 and the former 4, and then the formed circular ring enters the next process, realizing automated production, reducing the error caused by manual operation, improving the forming accuracy and consistency of the circular ring, and improving the yield rate of the circular ring. The utility model has a compact structure and is easy to use. It can realize the automated production of the circular ring of the steel plate 2, has a high degree of automation, improves the efficiency and accuracy of the processing of the circular ring of the steel plate 2, improves the quality of the product, reduces the labor cost of production, and improves the production efficiency.

[0091] A further optimized solution is that the forming rod 3 includes two symmetrically arranged limiting rods 5, with a connecting rod 6 disposed between the two limiting rods 5. The formed ring is wrapped around the connecting rod 6, and the two limiting rods 5 abut against the outer wall of the formed ring. The forming rod 3 is divided into two symmetrically arranged limiting rods 5, so that the spacing between them is adjustable. When circular forming is performed, the two sides of the steel plate 2 are abutted by the two limiting rods 5, which facilitates the production of rings of different widths. At the same time, the ring is wrapped around the connecting rod 6, which facilitates the positioning of the ring and improves the forming accuracy. When the forming is completed, the spacing between the two limiting rods 5 increases, and the clamped ring falls, is collected, and enters the next process.

[0092] A further optimization scheme involves a forming motor 7 connected to the end of the limiting rod 5, away from the connecting rod 6. The forming motors 7 are fixedly mounted on the frame 1 and interlocked. These two interlocked forming motors 7 synchronously rotate the two limiting rods 5, providing power for the ring forming process. Furthermore, the rotation speed and angle of the forming motors 7 are controllable, facilitating the shearing of the steel plate 2 by the cutting assembly and improving blanking accuracy.

[0093] As a further optimization, the frame 1 is provided with two symmetrically arranged adjustment frames 8, each equipped with a support block 9, through which the limiting rod 5 passes and is slidably connected. The support block 9 is mounted on the adjustment frame 8 to support the limiting rod 5, thereby improving stability, preventing the limiting rod 5 from shaking during the ring forming process, and improving the forming accuracy of the ring. At the same time, the limiting rod 5 can also slide on the support rod, without affecting the spacing adjustment between the two limiting rods 5.

[0094] In a further optimized solution, the end of the limit rod 5 that faces the forming motor 7 is rotatably connected to an adjusting nut 10. The adjusting nut 10 is threadedly connected to an output shaft 11 at the output end of the forming motor 7. The output shaft 11 of the forming motor 7 extends into the limit rod 5 and is transmission-connected to the limit rod 5. The output end of the forming motor 7 is transmission-connected to the output shaft 11. The output shaft 11 is provided with threads, which are threadedly connected to the adjusting nut 10 that is rotatably connected to the end of the limit rod 5. When the position of the two limit rods 5 needs to be adjusted, the adjusting nut 10 is rotated to change the depth of the transmission shaft extending into the limit rod 5, thereby driving the change in the spacing between the two limit rods 5.

[0095] In one embodiment of the present application, a plurality of limit grooves are provided on the outer wall of the transmission shaft, and a plurality of limit strips adapted to the limit grooves are provided in the transmission hole adapted to the transmission shaft at the end of the limit rod 5, so that the transmission shaft and the transmission hole can only slide but cannot produce relative rotation, so that the translation of the limit rod 5 is not affected during transmission.

[0096] In another embodiment of the present application, the threaded transmission shaft and the adjusting nut 10 can be replaced with hydraulic control, that is, a cavity for containing hydraulic oil is provided in the support block 9, and a force-bearing plate that slides sealed with the inner wall of the cavity is provided at the position where the limit rod 5 passes through the cavity. The force plate divides the cavity into two parts, and each part is separately connected to the hydraulic oil. When adjustment is required, the content of the hydraulic oil in the two parts of the cavity is controlled, and then the position of the force plate is adjusted to drive the limit rod 5 to slide.

[0097] In a further optimized solution, a forming frame 12 is provided on the frame 1, the top of the forming frame 12 is arranged obliquely toward the connecting rod 6, and the former 4 is fixedly mounted on the top of the forming frame 12. The top surface of the forming frame 12 is arranged obliquely toward the connecting rod 6, and the two are symmetrically arranged on both sides of the connecting rod 6, thereby enabling the movable end of the former 4 to be tilted and telescopically moved toward the connecting rod 6, thereby being able to abut against the outer wall of the formed circular ring, and then applying external force through the former 4 to promote the forming of the circular ring, thereby improving the forming efficiency and the forming quality.

[0098] A further optimization scheme features a forming block 13 fixedly mounted at the output end of the former 4. A forming wheel 14 is mounted on this block 13, abutting the outer wall of the formed ring. Mounted at the output end of the former 4, the forming block 13 can be driven by the former 4 to move closer to or further away from the ring formed on the connecting rod 6. The forming wheel 14 rotates on the forming block 13, abutting the outer wall of the forming wheel 14 against the outer wall of the ring. This creates rolling friction between the forming block 13 and the ring, resulting in low frictional resistance, minimal wear on the equipment, and reduced maintenance.

[0099] To further optimize the solution, the cutting assembly includes a telescopic cutting rod 15 arranged below the frame 1. The output end of the telescopic cutting rod 15 is transmission-connected to a cutting block 16 that slides telescopically on the frame 1. The cutting block 16 is arranged between the former 4 and the connecting rod 6 on the side where the steel plate 2 is fed. When forming a circular ring, the two forming motors 7 drive the circular ring to rotate one circle through the two limit rods 5, and then the telescopic cutting rod 15 is started to raise the cutting block 16, cutting the steel plate 2 through the cutting edge of the cutting block 16. The circular ring is then rotated again to tighten the interface with the circular ring, and the circular ring is formed. No excess waste is generated in this process, reducing the waste of raw materials.

[0100] In one embodiment of the present application, the cutting telescopic rod 15 uses a compressed air or hydraulic oil drive rod, which has low cost, sufficient driving force, and is convenient for cutting the steel plate 2; these two driving methods are both existing technologies, and technicians in this field are clear about how to arrange the supporting structural facilities, which will not be repeated here.

[0101] A further optimized solution includes a feed assembly comprising a feed block 17 fixedly mounted on the frame 1. This feed block 17 is drivingly connected to a feed wheel 18 for feeding the steel plate 2. The feed wheel 18 is in driving connection with a feed motor 19 mounted on the frame 1. When feeding is required, the feed motor 19 rotates the feed wheel 18, thereby providing power for feeding the steel plate 2. The feed speed of the feed motor 19 is interlocked with the rotation speed of the forming motor 7, matching the feeding speed with the forming speed, thereby enhancing forming automation.

[0102] To further optimize the solution, the outer wall of the feeding wheel 18 is provided with a feeding trough 20 for driving the steel plate 2 to move, and the feeding trough 20 is adapted to the steel plate 2. The feeding trough 20 is adapted to the steel plate 2 so that the steel plate 2 does not shake, thereby improving the feeding accuracy.

[0103] In the description of the present invention, it should be understood that the terms "longitudinal", "transverse", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, they should not be understood as limitations on the present invention.

[0104] The embodiments described above are merely preferred embodiments of the present invention and are not intended to limit the scope of the present invention. Without departing from the spirit of the present invention, various modifications and improvements to the technical solutions of the present invention made by ordinary technicians in this field should fall within the scope of protection determined by the claims of the present invention.
