Description

Technical Field

[0001] The present invention relates to the technical field of ultrasonic vibration processing, and particularly relates to an ultrasonic vibration-assisted vacuum hot pressing device. Background Art

[0002] The ultrasonic vibration-assisted hot pressing process can effectively reduce the flow stress of metal workpieces during the forming process, and to a certain extent, can promote the change of microstructure and the formation of texture.

[0003] For some workpieces that need to avoid high-temperature oxidation during the hot pressing process and require a certain degree of vacuum environment, it is necessary to supplement a certain pressure of inert gas, such as nitrogen or argon, for gas protection.

[0004] The existing ultrasonic vibration-assisted vacuum hot pressing device is designed as a cavity with a front-opening movable door, which is relatively easy to achieve in terms of structural design. However, in order to meet the operating space and visual space required for manual loading and unloading of molds and taking and placing materials, a large cavity space and door opening design are required. The spatial design scale needs to far exceed the mold scale. At the same time, to meet the vacuum degree requirements, a larger cavity design requires a larger wall thickness to meet the strength and stiffness requirements, and requires a longer vacuum pumping time and higher energy consumption, resulting in high manufacturing costs, high energy consumption, and low production efficiency. Summary of the Invention

Detailed implementation manners

[0028] In order to make the objectives, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0029] As Figure 1 shown, an ultrasonic vibration-assisted vacuum hot pressing device of the present invention includes a connected upper assembly 1 and a lower assembly 2; an ultrasonic vibrator assembly 13 is provided in the upper assembly 1, and the ultrasonic vibrator assembly 13 includes an ultrasonic transducer 134 and an ultrasonic horn 135, and a water-cooled seal guide sleeve 14 is connected to the lower end of the ultrasonic horn 135.

[0030] The lower assembly 2 is respectively connected to an externally connected vacuum protection gas pipeline and a temperature sensor. A mold assembly 26 is arranged inside the lower assembly 2. The mold assembly 26 includes a heat preservation cylinder 263, an upper mold 261 and a lower mold 262 which are arranged up and down inside the heat preservation cylinder 263, and an ultrasonic horn 135 can be inserted into the upper mold 261 and the lower mold 262.

[0031] A heating coil fixing assembly 22 is connected to the side wall of the lower assembly 2. The heating coil fixing assembly 22 includes an induction heating coil 221 connected to the heat preservation cylinder 263, and the induction heating coil 221 is connected to an externally connected high-frequency induction heating machine.

[0032] In the present invention, a first induction heating isolation plate 17 is arranged on the upper assembly 1, and a second induction heating isolation plate 27 corresponding to the first induction heating isolation plate 17 is arranged at the position of the heat preservation cylinder 263 inside the lower assembly 2; specifically, copper, a non-ferromagnetic material, is used as the isolation material to arrange the first induction heating isolation plate 17 and the second induction heating isolation plate 27, effectively reducing the consumption of additional heating power. Experiments on the isolation effect of high-frequency alternating magnetic fields on different materials were carried out. The experimental design and test data are shown in Figure 7 As shown, it can be seen that both pure copper and pure aluminum can significantly reduce the temperature rise of the isolated material and at the same time significantly reduce the input power; the first induction heating isolation plate 17 and the second induction heating isolation plate 27 are made of non-ferromagnetic metal materials with a thickness of not less than 1 mm, and are only configured when the sealing cover plate and the sealing box body are made of carbon steel, and are connected and fixed to the sealing box body cover plate through heat-conducting glue.

[0033] In the present invention, a sealing cover plate guiding assembly 18 is arranged on the upper assembly 1. The sealing cover plate guiding assembly 18 includes a sealing box body cover plate 185, a pull rod guide post 183 and a mold spring 182. The upper end of the mold spring 182 is fixedly connected to the vibrator connecting plate 131 through the pull rod guide post 183 and an inner hexagonal screw 181, and the lower end of the mold spring 182 is connected to the sealing box body cover plate 185 through the pull rod guide post 183.

[0034] The lower assembly 2 includes a sealing box body 281. The sealing box body 28 includes a sealing box body main body 281, a welded fixed bottom plate 282 and a welded support bottom plate 283. A water cooling plate 24 is arranged between the welded fixed bottom plate 282 and the welded support bottom plate 283, and the water cooling plate 24 is connected to the sealing box body main body 281 through heat-conducting glue.

[0035] Specifically, holes are arranged at one end of the sealing box body 28 for connecting the vacuum and protection gas pipelines and the temperature sensor; as Figure 3As shown, the sealed box body 28 is composed of a sealed box body main body 281, a welded fixed bottom plate 282 and a welded support bottom plate 283. An installation space for the water-cooled plate 24 is formed between the welded fixed bottom plate 282 and the welded support bottom plate 283. The water-cooled plate 24 is connected to the bottom plate of the sealed box body main body 281 through a thermal conductive adhesive. The whole device includes a total of 6 water-cooled plates at 3 typical positions, namely the water-cooled plate 15, the water-cooled plate 24 and the water-cooled plate 29, so that the temperature of the box body can be effectively dissipated.

[0036] In the present invention, the mold assembly 26 is composed of an upper mold 261, a lower mold 262 with a pin shaft hole and a mold heat preservation cylinder 263 for heat preservation. The mold positioning pin 23 fixes the mold heat preservation cylinder 263 and the second induction heating isolation plate 27.

[0037] A sealed cover lower guide sleeve 16 is provided on the sealed box body cover 185, and a sealed cover positioning pin 21 corresponding to the sealed cover lower guide sleeve 16 is provided on the sealed box body 28.

[0038] The present invention includes a quick clamp lock 19. The quick clamp lock 19 includes a corresponding quick clamp lock body 191 and a quick clamp lock hook 192. The quick clamp lock body 191 is connected to the upper assembly 1, and the quick clamp lock hook 192 is connected to the lower assembly 2; as Figure 3 shown, the silicone sealing strip 25 is made of silicone material, with a D-shaped or double-D-shaped cross-section and a hollow interior. It is connected to the upper end face of the sealed box body 28 through the silicone sealing strip 25. The mold spring 182 applies a pressing force to the silicone sealing strip 25 between the sealed box body cover 185 and the sealed box body 28, thereby generating a sealing effect, and at the same time further locking and fixing the quick clamp lock 19, so as to ensure the sealing reliability of the hot pressing device under the action of positive and negative air pressures of vacuum and protective gas. The locking action of the quick clamp lock 19 is realized by the tension of the quick clamp lock body 192 on the quick clamp lock hook 191.

[0039] In the present invention, the connection between the sealed box body 28 and the sealed box body cover 185 is positioned through the sealed cover positioning pin 21 and the sealed cover lower guide sleeve 16. After the sealed box body 28 and the sealed box body cover 185 are connected, the carbon steel materials horizontally arranged above and below the induction heating coil 221 will be in the induction area, resulting in unnecessary heating power loss.

[0040] Within the present invention, the ultrasonic vibrator assembly 13 further includes a vibrator connection plate 131 and a vibrator fixing pressure plate 132. The vibrator connection plate 131 is connected to the upper frame connection plate 11 through the spacer column assembly 12. The vibrator fixing pressure plate 132, the ultrasonic transducer 134, and the vibrator connection plate 131 are fixedly connected by internal hexagonal screws 133. The spacer column assembly 12 includes a spacer column 121 and a hexagonal nut 122. The vibrator connection plate 131 and the upper frame connection plate 11 are fixedly connected by the hexagonal nut 122 and the spacer column 121. Specifically, the ultrasonic vibrator assembly 13 is connected to the upper frame connection plate 11 through the spacer column assembly 12. The upper frame connection plate 11 is connected to the moving part of the press. The spacer column assembly 12 is composed of a spacer column 121 and a hexagonal nut 122. The designed height of the spacer column 121 is determined by the height of the upper part of the fixed section of the ultrasonic vibrator 13. The ultrasonic vibrator assembly 13 is composed of a vibrator connection plate 131, a vibrator fixing pressure plate 132, internal hexagonal screws 133, an ultrasonic transducer 134, and an ultrasonic horn 135. The ultrasonic horn 135 is connected to the sealing box cover plate 185 through a water-cooled sealing guide sleeve 14. The water-cooling effect of the water-cooled sealing guide sleeve 14 can avoid overheating of the seal inside the water-cooled sealing guide sleeve 14 caused by the high temperature at the end of the ultrasonic horn 135 and avoid overheating and failure of the ultrasonic transducer caused by heat conduction.

[0041] Within the present invention, the water-cooled seal guide sleeve 14 includes a seal guide sleeve base body 147, a copper flange bushing 146, and a four-way joint 144. The seal guide sleeve base body 147 is connected to the lower end of the upper assembly 1. The left and right ports of the four-way joint 144 are respectively used for water inlet and outlet. The upper port of the four-way joint 144 is sleeved on the ultrasonic horn 135 through a seal nut 141, and the lower port of the four-way joint 144 is connected to the inside of the seal guide sleeve base body 147 through the copper flange bushing 147. Specifically, the relative position between the seal box cover plate 185 and the ultrasonic horn 135 when not in operation is determined by the seal cover guide assembly 18. The seal cover guide assembly 18 includes a seal box cover plate 185, an inner hexagon screw 181, a die spring 182, a pull rod guide post 183, and a seal cover upper guide sleeve 184. Among them, after the die spring 182 is locked between the pull rod guide post 183 and the inner hexagon screw 181, it will be in a compressed state. This compression force can resist the frictional force between the water-cooled seal guide sleeve 14 and the ultrasonic horn 135, so that the relative position between the lowermost end of the ultrasonic horn 135 and the bottom surface of the seal box cover plate 185 remains unchanged in the non-working mode. The water-cooled seal guide sleeve 14 is composed of a seal guide sleeve base body 147, a copper flange bushing 146, an expansion seal ring 143, a metal flat gasket 142, a silica gel flat gasket 145, a four-way joint 144, a seal nut 141, and a seal flat gasket 148. The seal between the seal guide sleeve base body 147 and the seal box cover plate 185 is achieved through the seal flat gasket 148. The ultrasonic horn 135 and the seal guide sleeve base body 147 are matched through the copper flange bushing 146, which can increase the stiffness of the ultrasonic horn 135 during the compression process. During the process of screwing the four-way joint 144 into the seal guide sleeve base body 147, the silica gel flat gasket 145 and the expansion seal ring 143 will be simultaneously pressed, so as to achieve the water seal inside the four-way joint 144 and the air seal between the lower end of the ultrasonic horn 135 and the outside. During the locking process of the lock nut 141, the metal flat gasket 142 and the expansion seal ring 143 will be pressed, so as to ensure the water seal at the upper part of the four-way joint 144. The function of the metal flat gasket 142 can effectively avoid the torsional effect of the four-way joint 144 or the lock nut 141 on the expansion seal ring 143 during the locking process, reduce the torsional rebound, and thus more effectively produce a tightening effect on the expansion seal ring 143. The cooling water passing through the four-way joint 144 can form a cold source in a relatively large area where the ultrasonic horn 135 is close to the expansion seal ring 143 to protect the expansion seal ring 143 in time. The sealing ability of the expansion seal ring 143 can be adjusted through the locking force, and the worn part can be compensated by increasing the locking force, so as to meet the use in an environment with large frictional losses. Inside the four-way joint 144, the cooling water flowing through it can cool the materials beside the expansion seal ring 143 in time, improve the service life of the expansion seal ring 143, thereby improving the sealing reliability between the ultrasonic horn 135 and the seal cover, and at the same time avoiding the ultrasonic horn 135 from conducting the mold temperature to the ultrasonic transducer and causing the transducer temperature to be too high and fail.

[0042] Within the present invention, the heating coil fixing assembly 22 further includes an electrical insulation board 223, a sealant 222, a metal pressing plate 224, an internal hexagon screw 225, and a cable waterproof joint 226. The sealant 222, the electrical insulation board 223, and the metal pressing plate 224 are fixedly connected to the lower assembly 2 by the internal hexagon screw 225. The cable waterproof joint 226 is sleeved on the induction heating coil. Specifically, the heating coil fixing assembly 22 is composed of an induction heating coil 221, a sealant 222, an electrical insulation board 223, a metal pressing plate 224, an internal hexagon screw 225, and a cable waterproof joint 226. Thread sealant needs to be applied to the threaded connection between the internal hexagon screw 225 and the sealed box body 28 to ensure sealing. The electrical insulation board 223 can be made of nylon. The use of the cable waterproof joint 226 facilitates the adjustment and positioning of the installation position of the high-frequency heating coil 221 and can achieve a good sealing effect. The cable waterproof joint 226 is composed of a waterproof joint base body 2261, a rubber seal 2262, a plastic pressing pawl 2263, a sealing nut 2264, a locking nut 2265, and a rubber flat washer 2266. By tightening the plastic pressing pawl 2263 and the rubber seal 2262 with the sealing nut 2264, it can effectively isolate the straight-section copper tube extending from the high-frequency heating coil from the outside air.

[0043] The present invention has the following advantages:

[0044] 1. By introducing the design of upper and lower opening and closing, the compactness of the design is improved, facilitating manual operation and observation, and no longer being limited to the design dimensions of the sealed box body itself.

[0045] 2. By introducing the design of the water-cooled sealing bushing 14, the sealing reliability between the ultrasonic horn 135 and the sealed box body cover plate 185 is improved, and the ultrasonic horn 135 is effectively cooled, avoiding the ultrasonic horn 135 from conducting the mold temperature to the ultrasonic transducer 134 and causing the transducer temperature to be too high and fail.

[0046] 3. By introducing the design of the induction heating isolation plate, the ineffective heating of the upper and lower surfaces of the carbon steel sealed box body by the high-frequency heating coil is effectively avoided, reducing the additional power output of the high-frequency heating system and lowering the energy consumption.

[0047] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
