Description

Technical Field

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

[0002] In recent years, high-efficiency forming (also known as high-speed forming) methods for metal materials have received extensive attention, such as explosive forming, electromagnetic forming, and impact forming, which are particularly suitable for efficient and precise forming of high-strength, low-plasticity metals. For example, high-strength steel, titanium alloy and other plates have high strength at room temperature and poor plasticity. The traditional low-speed forming process has significant springback, resulting in poor product dimensional accuracy and uneven internal stress distribution. It is often necessary to use heat treatment processes such as hot forming or aging, and the production efficiency is low. For example, the shearing of medium and large diameter high-strength metal bars requires extremely high equipment load, and usually requires high-temperature shearing of 800℃-1100℃, resulting in the material end being flattened by the shearing die and the cross section being "horseshoe-shaped". The high-speed impact forming technology significantly improves the forming ability and accuracy of the above materials through a high deformation rate of 103 / s−104 / s, greatly improving production efficiency and reducing equipment tonnage.

[0003] Existing high-speed impact forming equipment mainly adopts mechanical drive with motor driving flywheel, and liquid-gas drive using combustion or flow energy of liquid or gas as power. Mechanical drive equipment has a large structure, high cost, short mold life, and the actual forming speed is generally lower than 5-10m / s; while liquid-gas drive equipment relies on gas combustion or hydraulic oil compression to cause pipeline cooling heat dissipation, and has different degrees of complex hydraulic system, low energy utilization, fuel combustion or waste hydraulic oil pollution, low processing efficiency and other problems.

[0004] Therefore, there is an urgent need for a composite energy storage type high-speed servo impact device with simple structure, low cost and high efficiency. Summary of the invention

[0005] The purpose of the present invention is to provide a composite energy storage high-speed servo impact device and a method of use that can meet the actual industrial needs of high efficiency, simple structure and low cost to overcome the shortcomings of the prior art such as complex hydraulic systems and low energy utilization.

[0006] In order to achieve the above object, the present invention provides the following technical solutions: In a first aspect, a composite energy storage high-speed servo impact device is provided. It includes a combined body, an energy storage impact mechanism, a servo hammer mechanism and a locking and releasing mechanism; The combined fuselage comprises an upper box and a lower box, and the upper box and the lower box are connected by a column; the energy storage impact mechanism is embedded in the upper box, which improves the energy utilization efficiency and reduces the overall volume of the device; the servo hammer mechanism is arranged on both sides of the upper box; The energy storage impact mechanism includes a cylinder, the upper chamber of the cylinder is connected to the external air storage chamber through the upper end cover and the air valve, the lower chamber is embedded in the upper box body and fixed to the bottom plate of the upper box body through the end cover, a piston rod is arranged in the lower chamber, one end of the piston rod is fixedly connected to the piston, which can quickly store and release gas energy to produce a high-speed impact effect, the other end of the piston rod is fixedly connected to the hammer head, and the column passes through the four corners of the hammer head and is connected to the lower box body; an elastic device is arranged on the upper surface of the hammer head and the lower surface of the bottom plate of the upper box body, and the elastic device is used for compound energy storage acceleration to make the impact speed of the hammer head higher; the locking and releasing mechanism is fixed to the four corners of the hammer head and is mounted on the column to realize the locking and release of the hammer head.

[0007] Furthermore, the servo hammer lifting mechanism includes a servo motor, the input end of the servo motor is connected to a reducer, and the reducer is fixedly connected to the upper box body through a fixing mechanism; the output end of the reducer is connected to an active reel, one end of a steel belt is wound on the active reel, and the other end of the steel belt is fixedly connected to a passive reel, and the passive reel is fixed to the hammer head through a reel core shaft; the servo motor drives the active reel to rotate through the reducer, and the steel belt wound on the active reel drives the passive reel and the hammer head to rise and fall.

[0008] Furthermore, the fixing mechanism includes a triangular bracket, a support seat is provided on the triangular bracket, the triangular bracket is arranged on the left and right sides of the upper box body, the reducer is fixed to the triangular bracket through a bearing, and the fixing mechanism enhances the stability of the reducer.

[0009] Furthermore, the locking release mechanism includes a wedge-shaped slip, which is slidably connected to the column and a wear-resistant gasket is provided on the side of the wedge-shaped slip in contact with the column. A wedge-shaped slip ring is fixed on the wedge-shaped slip, and the wedge-shaped slip ring is connected to an external gas-liquid booster. The sliding of the wedge-shaped slip is controlled by gas pressure or hydraulic pressure, thereby achieving rapid response and precise control of the locking release mechanism.

[0010] Furthermore, the elastic device includes guide pillars and springs. The four guide pillars are connected to the lower surface of the bottom plate of the upper box body. Through holes are opened at positions of the hammer head corresponding to the guide pillars, and springs are arranged on the guide pillars.

[0011] Furthermore, the spring is a high-energy spring.

[0027] The present invention provides a high-speed servo impact device with high-pressure gas and high-energy spring composite energy storage, which uses a high-speed cylinder and a high-energy spring two-stage drive to achieve the required impact energy and speed requirements, and better meet the actual industrial needs of high efficiency, simple structure and low cost. The device can not only perform high-speed impact forming of high-strength metals, but also can be used as a high-speed mechanical test device for scientific research institutes and colleges and universities.

[0028] Example 1 See also Figure 1 to Figure 2 , a composite energy storage high-speed servo impact device, comprising a combined body, an energy storage impact mechanism, a servo hammer mechanism and a locking and releasing mechanism; The combined fuselage comprises an upper box body 5 and a lower box body 15, and the upper box body 5 and the lower box body 15 are connected by a column 13; the energy storage impact mechanism is embedded in the upper box body 5, and the servo hammer mechanism is arranged on both sides of the upper box body 5; the servo hammer mechanism adopts advanced servo control technology, has the characteristics of fast response speed and high positioning accuracy, and avoids the problems of pipeline cooling heat dissipation and oil-gas mutual channeling that may be caused by traditional hydraulic drive; The energy storage impact mechanism includes a cylinder 2, the upper chamber of the cylinder 2 is connected to the external air storage chamber through the upper end cover 1 and the air valve, and the initial pressure of the upper chamber of the cylinder 2 is adjusted by adding high-pressure gas, so that the impact speed and energy can be flexibly controlled to meet the needs under different working conditions. The lower chamber is similar to a vacuum chamber, and the lower chamber is embedded in the upper box body 5 and fixed to the bottom plate of the upper box body 5 through the lower end cover 7. A piston rod 3 is arranged in the lower chamber, and a piston is fixedly connected to one end of the piston rod 3, and a hammer head 12 is fixedly connected to the other end of the piston rod 3, and the column 13 passes through the four corners of the hammer head 12 and is connected to the lower box body. body 15; elastic devices are arranged on the upper surface of the hammer head 12 and the lower surface of the bottom plate of the upper box body 5, so that the hammer head 12 can impact the target at a higher speed under the joint action of the high-pressure gas and the elastic device, thereby improving the impact efficiency; the locking and releasing mechanism is fixed to the four corners of the hammer head 12 and is sleeved on the column 13, and can reliably lock the hammer head 12 after the hammer head 12 is lifted into place to prevent it from being displaced or falling off during the impact process. When the hammer head 12 needs to be released for impact, the locking and releasing mechanism can be quickly unlocked, so that the hammer head 12 can impact the target at a high speed under the action of the energy storage impact mechanism.

[0029] In some preferred embodiments of the present invention, the elastic device includes guide columns 9 and springs 11. The four guide columns 9 are connected to the lower surface of the bottom plate of the upper box body 5. A through hole is opened at the position of the hammer head 12 corresponding to the guide column 9, and a spring 11 is arranged on the guide column 9. The spring 11 is used for composite energy storage acceleration during the impact process to make the hammer head impact speed higher.

[0030] In some preferred embodiments of the present invention, the spring 11 is a high-energy spring, which has a higher energy storage capacity and more stable performance, and can provide a greater impact force to the hammer head 12 during the impact process while ensuring the stability and accuracy of the impact.

[0031] The top plate of the lower box 15 is installed with a T-slot platform 14, which is a flat workbench with a T-slot, and can be used to install, fix and debug various equipment and tools. In this device, the introduction of the T-slot platform 14 makes the top plate of the lower box 15 more flexible and multifunctional, and other related equipment or components can be easily installed and debugged.

[0032] The column 13 is fixedly connected between the upper box 5 and the lower box 15 by the first super nut 4 and the second super nut 16. This connection method not only ensures the stability and rigidity of the column 13, but also makes the structure of the entire device more compact and firm. The super nut has the characteristics of high strength and wear resistance, and can withstand huge pressure and torque.

[0033] Example 2 See also Figure 2 , based on Example 1, the servo hammer mechanism is further described. The servo hammer mechanism includes a servo motor 6. The servo motor 6 serves as a power source. Its input end is connected to a reducer 23. The reducer 23 is fixedly connected to the upper box 5 through a fixing mechanism. The output end of the reducer 23 is connected to an active reel 20. The power output by the servo motor can be transmitted to the active reel 20 after being decelerated and torque-increased by the reducer. The active reel 20 is a cylindrical component, and one end of the steel belt 10 is wound on its surface. The steel belt 10 is a high-strength, high-wear-resistant transmission belt. It has good flexibility and load-bearing capacity and can reliably transmit power and torque. The other end of the steel belt 10 is fixedly connected to a passive reel 22. The passive reel 22 is a cylindrical component similar to the active reel 20, but it is fixed to the hammer head 12 through a reel core shaft 17. The reel core shaft 17 is a shaft-like part, which passes through the center hole of the passive reel 22 and is firmly connected to the passive reel 22. The other end of the reel core shaft 17 is connected to the hammer head 12, which may be achieved by fasteners such as bolts and nuts, or by welding.

[0034] When the servo motor 6 is started, it drives the reducer 23 to rotate, thereby driving the active reel 20 to rotate. The rotation of the active reel 20 pulls the steel belt 10, causing it to bypass the passive reel 22 and drive it to rotate. Since the passive reel 22 is connected to the hammer 12 through the reel core shaft 17, when the passive reel 22 rotates, it drives the hammer 12 to rise or fall together.

[0035] In some preferred embodiments of the present invention, the fixing mechanism includes a triangular bracket 8, on which a support seat 21 is provided, which provides a stable support for the reducer 23 and ensures its stability and reliability during operation. The support seat 21 and the triangular bracket 8 are connected with fasteners such as bolts and nuts to ensure the firmness and reliability of the connection; the triangular bracket 8 is arranged on the left and right sides of the upper box body 5, and the reducer 23 is fixed to the triangular bracket 8 by a bearing 19.

[0036] The bearing 19 is a mechanical element that can support rotating parts and reduce friction and wear. The bearing 19 is mounted on the triangular bracket 8 and connected to the output shaft or mounting seat of the reducer 23, which reduces the friction and wear between the reducer 23 and the triangular bracket 8 and improves the transmission efficiency. Through the support and lubrication of the bearing 19, the reducer 23 can rotate smoothly and transmit power to the active reel 20.

[0037] Example 3 See also Figures 1 to 4 On the basis of Example 2, the locking release mechanism is further described, and the locking release mechanism includes a wedge-shaped slip 24, which is slidingly connected to the column 13, and a wear-resistant gasket 25 is provided on the side of the wedge-shaped slip 24 that contacts the column 13, and a wedge-shaped slip ring 26 is fixed on the wedge-shaped slip 24, and the wedge-shaped slip ring 26 is connected to an external gas-liquid booster.

[0038] During specific use, a four-petal wedge-shaped cava 24 is used to achieve the locking and releasing functions of the hammer head 12 and its related components through a sliding connection with the column 13. The design of the wedge-shaped cava 24 enables it to slide along the axial direction of the column 13 when subjected to external force, thereby changing its relative position with the column.

[0039] The wear-resistant pad 25 is arranged on the side where the wedge-shaped slip 24 contacts the column 13, and its main function is to reduce the friction and wear between the wedge-shaped slip 24 and the column 13, and improve the durability and service life of the locking release mechanism. The wear-resistant pad 25 is usually made of high-strength and high-wear-resistant materials, such as stainless steel, alloy steel, etc.

[0040] The wedge slip ring 26 is fixed on the wedge slip 24. Its function is to connect the external gas-liquid booster and transmit the pressure generated by the gas-liquid booster to the wedge slip 24, so as to realize the driving and control of the wedge slip 24. The design of the wedge slip ring 26 enables it to cooperate closely with the external gas-liquid booster to ensure the accurate transmission of pressure and the stable operation of the locking and releasing mechanism.

[0041] When the hammer 12 and its related parts need to be locked, the external gas-liquid booster generates pressure, which is transmitted to the wedge-shaped slip 24 through the wedge-shaped slip ring 26. Under the action of pressure, the wedge-shaped slip 24 slides along the column 13 until it is clamped on the column 13 to achieve the locking function. At this time, the hammer 12 and its related parts are firmly fixed in the specified position and cannot move or fall off.

[0042] Example 4 The present invention also provides a method for using a composite energy storage high-speed servo impact device, comprising the following steps: Filling the upper chamber of the cylinder 2 of the energy storage impact mechanism with gas of initial pressure through the external gas storage chamber; The steel wire rope 10 lifts the hammer head 12 to a specified height, and the compressed gas and the compressed spring 11 perform double energy storage; Hydraulic oil is charged into the wedge-shaped slip ring 26 through an external gas-liquid booster, and the wedge-shaped slip 24 locks the hammer head 12; The wedge-shaped slip ring 26 releases oil, and the wedge-shaped slip 24 releases the hammer head 12 to achieve high-speed impact.

[0043] The working principle is described in detail: in the hammer lifting and energy storage stroke, the upper chamber of the high-speed cylinder 2 of the energy storage impact mechanism is filled with nitrogen of initial pressure through the external air storage chamber, and the symmetrically arranged servo motor 6 drives the active reel 20 to rotate through the reducer 23. The steel belt 10 wound on the active reel 20 lifts the hammer head 12 to the set height through the passive reel 22. The lower chamber of the wedge-shaped slip ring 26 of the hammer lifting and releasing mechanism is filled with hydraulic oil through the external gas-liquid booster, driving the wedge-shaped slip ring 26 to slide upward and horizontally tighten the 4-petal wedge-shaped slips 24 and the wear-resistant gasket 25, locking the hammer head 12 on the four columns 13. After the hammer lifting is completed, the nitrogen in the upper chamber of the cylinder 2 is compressed by the piston 1 and stores the set pressure potential energy, and the high-energy spring 11 is compressed by the hammer head 12 and stores the set elastic potential energy.

[0044] During the high-speed impact stroke, the hydraulic oil in the upper chamber of the wedge-shaped slip ring 26 of the hammer release mechanism quickly flows back, the hammer head 12 is quickly released, and the energy of the spring 11 and the cylinder 2 is released instantly. Under the combined action of the hammer head gravity potential energy, nitrogen pressure potential energy, and spring elastic potential energy, the hammer head 12 is quickly released to achieve high-speed impact loading.

[0045] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any form. Any ordinary technician in the industry can smoothly implement the present invention as shown in the drawings and described above. However, any equivalent changes, modifications and evolutions made by technicians familiar with the profession without departing from the scope of the technical solution of the present invention using the technical content disclosed above are all equivalent embodiments of the present invention. At the same time, any equivalent changes, modifications and evolutions made to the above embodiments based on the essential technology of the present invention are still within the protection scope of the technical solution of the present invention.
