Description

Technical Field

[0001] The invention relates to the technical field of high-speed impact forming, and in particular to a composite energy storage type high-speed forming device and a use method thereof. Background Art

[0002] In modern manufacturing, the requirements for precision and efficiency in material processing are increasing, especially in the field of forming processing of high-strength metal materials. This field is crucial for achieving lightweight structures, improving mechanical properties, and meeting the needs of complex shape manufacturing. High-energy forming (also known as high-speed forming) belongs to the category of dynamic loading technology, which can release energy quickly in a very short time, significantly improve metal forming ability and forming quality, greatly reduce processing passes, and improve processing efficiency. With the advancement of technology, high-speed impact forming technology, which processes high-strength metal materials at high energy and high speed, has occupied an important position in the manufacturing industry because it can release a large amount of energy in a short time and significantly improve metal forming ability and quality.

[0003] In the existing high-speed impact forming technology, commonly used methods include electromagnetic forming, electro-hydraulic forming and traditional drop hammer forming. These technologies meet the needs of high-speed forming to a certain extent, but there are also significant problems. Among them, the traditional drop hammer mainly uses the method of lifting the hammer head by pulling the wire rope with the motor. The impact energy mainly comes from the gravitational potential energy of the hammer head. The impact speed is generally lower than 5.5m / s, which cannot meet the high-speed impact requirements required for the processing of some high-performance materials. In addition, although some drop hammers have added spring compression energy storage devices, which can increase the impact speed of the device to a certain extent, long-term and frequent compression deformation will cause the spring to be easily fatigued and have a low service life. At the same time, the above-mentioned drop hammer equipment has low striking efficiency and a large body height. It is mainly suitable for mechanical testing of small-sized specimens and is not suitable for high-speed impact forming of metal materials. Although liquid-gas impact equipment has certain applications in the field of forming processing, they generally have problems such as complex hydraulic systems and oil-gas crosstalk. These problems not only increase the difficulty of equipment maintenance, but also limit processing efficiency and precision. These problems have led to the fact that in actual production, these devices are difficult to meet large-scale and high-efficiency processing needs, especially in application scenarios with extremely high requirements for forming speed and energy control.

[0004] In order to overcome the limitations of the existing technology, improve the impact speed and processing efficiency of the drop hammer, extend the service life of the equipment, and meet the needs of continuous high-speed impact forming processing, a new high-speed forming device is urgently needed. Summary of the invention

[0005] The object of the present invention is to provide a composite energy storage high-speed forming device and a method of using the same, so as to overcome the shortcomings of the existing high-speed forming devices, such as low striking efficiency and great maintenance difficulty.

[0006] In order to achieve the above object, the present invention adopts the following technical solution: A composite energy storage high-speed forming device, comprising: The combined fuselage, as the main structure of the entire device, provides support and installation foundation, carries and connects other components, and ensures the stability and rigidity of the overall structure. An energy storage and speed increase mechanism is fixedly connected to the upper part of the combined fuselage, and an impact tube is installed on the upper part. The upper end of the impact tube is connected to the energy storage and speed increase mechanism, and the impact tube is connected to the piston of the hammer mechanism. A pneumatic hammer lifting mechanism is fixed to the lower part; The energy storage and speed increasing mechanism is filled with high-pressure gas, which provides energy through the high-pressure gas filled inside, and releases the gas to accelerate the hammer head to achieve high-speed impact. A gas-controlled piston valve is installed at the bottom of the energy storage and speed increasing mechanism, and the energy storage and speed increasing mechanism is connected to the hammer head mechanism through an impact tube; A pneumatic hammer lifting mechanism is arranged at the lower part of the combined fuselage, and the pneumatic hammer lifting mechanism includes a cylinder. When the cylinder is filled with air, the pneumatic hammer lifting mechanism contacts the hammer head mechanism, driving the hammer head mechanism to rise to the electromagnetic locking mechanism for locking, thereby realizing a rapid return of the hammer head mechanism; The electromagnetic locking mechanism is used to lock and release the hammer mechanism, and is fixed at the highest point of the ascending path of the hammer mechanism to ensure the stability of the hammer during the energy storage stage and quickly release the hammer during the impact stage; The hammer mechanism is connected to the impact tube piston to directly impact the target material at high speed, thereby realizing high-speed impact forming processing of metal materials.

[0007] Furthermore, the combined fuselage includes ribs and an upper box body, the upper box body is welded on the box body bottom plate, the ribs are connected to the side surfaces of the upper box body and the top of the box body bottom plate, and the box body bottom plate is connected to the base through four columns, thereby ensuring the structural stability and load-bearing capacity of the entire composite energy storage high-speed forming device.

[0008] Furthermore, the energy storage and speed increasing mechanism includes a high-pressure cylinder, which serves as a storage place for high-pressure gas and provides the energy required for impact. A support frame is fixed inside the high-pressure cylinder, and the support frame is cross-shaped. An upper end cover is installed above the high-pressure cylinder, and a lower end cover is installed below the high-pressure cylinder; a first air inlet joint and a second air inlet joint are arranged on the upper end cover, the first air inlet joint is used to supply air to the high-pressure cylinder, and the second air inlet joint is used to supply air to the upper chamber of the piston; the lower end cover is installed on the combined fuselage, and an impact port is opened in the middle, and the impact port is connected to the upper end of the impact tube to realize the connection of the high-pressure gas between the energy storage and speed increasing mechanism and the hammer head mechanism.

[0009] Furthermore, the air-controlled piston valve is installed on the support frame through an end cover, and a connecting pipe is installed on the upper surface of the end cover and is connected to the second air inlet connector; the air hole piston valve includes a piston, and the piston is fixedly connected to a wedge-shaped plug through a piston rod, and an air hole is opened in the lower chamber of the piston, and the upper chamber of the piston is filled with gas of preset pressure, and the lower chamber is connected to the high-pressure air chamber through the air hole.

[0010] Furthermore, the upper end cover and the lower end cover are installed with the high-pressure cylinder through a plurality of tightening screws and nuts, and the upper and lower ends of the high-pressure cylinder are closed to ensure gas sealing.

[0011] Furthermore, the pneumatic hammer lifting mechanism contacts with the hammer head mechanism through a support plate, and the pneumatic hammer lifting mechanism includes two cylinders, and the two cylinders are started synchronously. The bottom surface of the cylinder is fixed to the base at the bottom of the combined fuselage, and a top plate is installed on the upper end of the cylinder rod in the cylinder, and the top plate is connected to the support plate through a connecting rod. The pneumatic hammer lifting mechanism is inflated by the cylinder, and the cylinder rod drives the support plate to be lifted through the connecting rod. The support plate contacts with the hammer head mechanism, thereby driving the hammer head mechanism to be lifted together.

[0012] Furthermore, the electromagnetic locking mechanism includes a support plate and four electromagnetic suction cups, the support plate is fixedly connected to the bottom end of the impact tube, and the electromagnetic suction cups are fixed to the bottom surface of the support plate.

[0013] Furthermore, the hammer mechanism includes a hammer and a hammer rod, the lower end of the hammer rod is fixedly connected to the hammer, and the upper end of the hammer rod is connected to the impact tube piston through a first piston.

[0014] Furthermore, a guide post is installed at the bottom of the combined fuselage, and the four corners of the hammer head are provided with matching through holes to be sleeved with the guide post and slide vertically along the guide post. The support plate is fixed on the shoulder of the guide post, and the guide post is fixedly connected to the bottom plate of the box body and the bottom plate.

[0015] A method for using a composite energy storage type high-speed forming device is applicable to a composite energy storage type high-speed forming device, and the method comprises the following steps: S1, open the air source to inflate the energy storage and speed increasing mechanism to a preset value; S2, locking the hammer mechanism to the highest point of its ascending path through the electromagnetic locking mechanism; S3, controlling the energy storage and speed increasing mechanism to release the high-pressure gas, and at the same time controlling the electromagnetic locking mechanism to release the hammer mechanism; S4, starting the pneumatic hammer lifting mechanism to lift the hammer head mechanism to the highest point of its ascending path, and the electromagnetic locking mechanism relocks the hammer head mechanism; S5, repeat S3 and S4 until the processing is completed.

[0016] Furthermore, during the rapid return stage of the device, air is taken in from the lower chambers of the two synchronous cylinders, pushing the cylinder rods to drive the top plate, connecting rod and support plate to move upward, and the hammer head is lifted by the support plate to quickly return until it is locked at a specified height after being adsorbed by a strong electromagnetic suction cup; the upper chamber of the air-controlled piston valve is filled with gas of preset pressure through the connecting pipe and the second air inlet connector, pushing the piston downward and sealing the impact port through a wedge-shaped plug.

[0017] During the high-speed impact stage, high-pressure gas is filled into the high-pressure cylinder through the first air inlet joint. When the gas pressure exceeds the preset pressure of the piston valve, the high-pressure gas pushes the piston upward through the air hole and drives the plug to quickly open the impact port. At the same time, the strong electromagnetic suction cup releases the hammer head, allowing the high-pressure gas to quickly enter the impact tube through the impact port. The hammer head achieves high-speed impact loading under the push of its own weight and high-pressure gas.

[0018] Compared with the prior art, the present invention has the following beneficial technical effects: A composite energy storage high-speed forming device, by adopting the composite energy storage method of high-pressure gas potential energy and hammer head gravity potential energy, has achieved a breakthrough in the existing traditional drop hammer impact speed, significantly improved the ability and quality of metal forming, and met the requirements of high-performance material processing for high-speed impact. At the same time, it avoids the problems of easy spring fatigue and low service life in the spring energy storage device through the precise control of the pneumatic piston valve and the electromagnetic locking mechanism, reduces maintenance costs and frequency, and extends the service life of the equipment. In addition, the device has a compact structural design and a smaller body size than traditional drop hammer equipment, which is suitable for a wider range of application scenarios, including high-speed impact forming processing of metal materials. By precisely controlling the release of high-pressure gas, efficient energy utilization is achieved, energy consumption is reduced, and economy is improved. The electromagnetic locking mechanism provides stable locking of the hammer head during the energy storage stage, avoiding the risk of accidental release and enhancing the safety of operation.

[0019] A method for using a composite energy storage high-speed forming device, by using the above-mentioned high-speed forming device for processing and production, ensures the consistency and repeatability of the forming process, improves production efficiency and product quality, significantly improves production capacity, and meets the needs of large-scale production.

In addition, the device has strong adaptability and is suitable for the forming processing of various high-strength metal materials. It has good flexibility and can meet the processing requirements of different materials and shapes. The electromagnetic locking mechanism provides stable locking of the hammer head during the energy storage stage, which enhances the safety of operation. The design of using high-pressure gas as the power source makes the device energy-saving and environmentally friendly, helps to reduce energy consumption and carbon emissions, and is of great significance to achieving sustainable development and environmental protection. As a high-speed mechanical testing device for scientific research institutes, colleges and universities, the device can provide precise control and repeatable experimental results, promote the development of new materials and new processes, and provide a powerful tool for teaching and scientific research.

[0039] Embodiment 2: In a specific embodiment of the present invention, a method for using a composite energy storage type high-speed forming device is provided. The method is applicable to a composite energy storage type high-speed forming device, such as Figure 5 As shown, the method comprises the following steps: S1, open the air source to inflate the energy storage and speed increasing mechanism to a preset value; S2, locking the hammer mechanism to the highest point of its ascending path through the electromagnetic locking mechanism; S3, controlling the energy storage and speed increasing mechanism to release the high-pressure gas, and at the same time controlling the electromagnetic locking mechanism to release the hammer mechanism; S4, starting the pneumatic hammer lifting mechanism to lift the hammer head mechanism to the highest point of its ascending path, and the electromagnetic locking mechanism relocks the hammer head mechanism; S5, repeat S3 and S4 until the processing is completed.

[0040] When in use, first install the composite energy storage high-speed forming device in the processing area, and carry out necessary safety checks to ensure that all components are firmly connected and there is no leakage in the gas circuit and circuit. Then open the gas source, fill the compressed gas into the high-pressure cylinder through the first air inlet joint until the pressure reaches the preset value, and fill the compressed gas into the piston upper chamber of the air-controlled piston valve through the second air inlet joint until the pressure reaches the preset value. The high-pressure gas inside the energy storage speed-increasing mechanism provides energy for subsequent impacts.

[0042] During the high-speed impact stage, high-pressure gas is filled into the high-pressure cylinder through the first air inlet joint. When the gas pressure exceeds the preset pressure of the piston valve, the high-pressure gas pushes the piston upward through the air hole and drives the plug to quickly open the impact port. At the same time, the strong electromagnetic suction cup releases the hammer head, allowing the high-pressure gas to quickly enter the impact tube through the impact port. The hammer head achieves high-speed impact loading under the push of its own weight and high-pressure gas.
