[0033] Please refer to Figures 1 to 3 The embodiment of the present application provides a vacuum hot pressing forming device 100 for hot pressing target objects, which can be amorphous alloys. The vacuum hot pressing forming device 100 comprises a heating structure 202, a material loading structure 201 and a driving structure 203.

[0034] The heating structure 202 is fixedly arranged and used for heating the amorphous alloy. The heating structure 202 can heat the amorphous alloy to its glass transition temperature by resistance heating, so as to facilitate subsequent hot pressing forming of the amorphous alloy.

[0035] Please refer to Figures 2 to 4The carrier structure 201 is arranged in a vertical direction and below the heating structure 202, and the amorphous alloy is arranged in the carrier structure 201. It can be understood that the amorphous alloy is arranged on the upper surface of the carrier structure 201, and the amorphous alloy can be synchronously raised or synchronously lowered with the carrier structure 201 relative to the heating structure 202.

[0036] Please refer to Figures 2 to 4 The driving structure 203 is connected to the carrier structure 201, and drives the carrier structure 201 to move towards the heating structure 202. The carrier structure 201 drives the amorphous alloy to abut and press tightly the heating structure 202 upwards, so that the heating structure 202 heats the target object in a heat conduction manner, and the amorphous alloy can be hot-pressed. Through the heat conduction manner, heat can be quickly conducted to the amorphous alloy, and the temperature of the amorphous alloy can be raised to the glass transition temperature, so that the hot-pressing of the amorphous alloy can be realized. Through the heat conduction manner, heat can be accurately conducted to the amorphous alloy, and waste of heat can be avoided.

[0037] After the hot-pressing is completed, the driving structure 203 drives the carrier structure 201 to move in a direction away from the heating structure 202, that is, drives the carrier structure 201 to move downwards, and the hot-pressed amorphous alloy is synchronously moved downwards with the carrier structure 201, so that the amorphous alloy is separated from the heating range of the heating structure 202, heat continues to be conducted to the completed amorphous alloy, and the temperature of the heating structure 202 affects the formed amorphous alloy, so that the crystallization of the formed amorphous alloy can be avoided, and the forming quality is improved.

[0038] Please refer to Figures 2 to 4 The vacuum hot-pressing device 100 provided by the embodiment of the present application is arranged above the target object. After the driving structure 203 drives the carrier structure 201 to move upwards by a certain distance, the amorphous alloy abuts the heating structure 202, heat of the heating structure 202 can be conducted to the amorphous alloy, and the temperature of the amorphous alloy can be quickly raised to the glass transition temperature. The driving structure 203 drives the carrier structure 201 to press tightly the heating structure 202 upwards, so that the amorphous alloy at the glass transition temperature can be hot-pressed. After the hot-pressing is completed, the driving structure 203 drives the carrier structure 201 to move downwards, and the formed amorphous alloy is separated from the heating structure 202, so that the crystallization of the amorphous alloy can be avoided.

[0039] Please refer to Figures 2 to 4Optionally, the amorphous alloy can be placed in a forming die, the forming die is placed in the carrier structure 201, the heating structure 202 heats the amorphous alloy by heating the forming die, and at the same time, when the carrier structure 201 presses the heating structure 202 upward, the forming die can heat-press the amorphous alloy, so as to process a certain shape or structure on the surface of the amorphous alloy sample, or process a micro-nano structure or prepare other micro parts on the surface of the amorphous alloy sample, or convert the powder type or thin strip type amorphous alloy material into an amorphous alloy sample with a specific shape, such as a block or a column.

[0040] Please refer to Figures 2 to 4 It can be understood that, by fixing the heating structure 202 on the top of the equipment, and moving the carrier structure 201 up and down in the vertical direction through the driving structure 203, it is ensured that the heat can be accurately conducted to the amorphous alloy. The driving structure 203 moves the carrier structure 201 in the vertical direction, provides an upward and downward pressing function, makes the heat transfer concentrated and uniformly conducted to the forming die, and avoids the loss or heat diffusion of the heat in the horizontal direction.

[0041] The amorphous alloy is easy to crystallize after being heated, which causes the physical properties to degrade. The vacuum heat-pressing forming device 100 can heat-press the amorphous alloy on one hand, and quickly remove the amorphous alloy from the heating structure 202 after the heat-pressing is completed on the other hand, so as to avoid the problem of long continuous heating time and prevent the amorphous alloy from crystallizing due to long exposure to high temperature.

[0042] Optionally, the carrier structure 201 can be a heat insulation block made of a composite heat insulation material, and the heat insulation block can be made of mica or asbestos, which is not limited here and can be selected according to the actual situation.

[0043] Please refer to Figures 2 to 4 In one embodiment, the vacuum heat-pressing forming device 100 further includes a cooling structure, the cooling structure includes a material moving driver 42 and a guide seat 40 with a cooling area 402, the cooling area 402 is arranged in a horizontal direction offset to the heating structure 202, the carrier structure 201 is arranged in a horizontal direction sliding manner, and the material moving driver 42 is used to drive the carrier structure 201 to slide in the horizontal direction to the cooling area 402. The material moving driver 42 can be an electric push rod or other linear driver, and the material moving driver 42 can also be a pneumatic cylinder, which is not limited here and can be selected according to the actual situation.

[0044] Please refer to Figures 2 to 4Optionally, by arranging the cooling area 402 and the heating structure 202 in a staggered manner, the carrier structure 201 can be moved between different temperature areas, so that the target object is immediately transferred to the cooling area 402 for cooling after the hot pressing is completed, avoiding the heat radiation of the heating structure 202 to the amorphous alloy, so that the amorphous alloy after the hot pressing is not affected by high temperature, and the crystallization of the amorphous alloy is avoided. The material moving driver 42 can drive the carrier structure 201 to slide in the horizontal direction, so that the carrier structure 201 drives the amorphous alloy to slide in the horizontal direction, so that the amorphous alloy can be quickly moved from the radiation range of the heating structure 202 to the cooling area 402, avoiding staying in a high-temperature environment for too long, thereby avoiding the crystallization of the amorphous alloy.

[0045] Referring to Figure 3 In some embodiments, the cooling structure further comprises a longitudinal rod 421 connected to the material moving driver 42, and a transverse rod 422 connected to the longitudinal rod 421, the axial direction of the transverse rod 422 being perpendicular to the axial direction of the longitudinal rod 421, the transverse rod 422 being capable of abutting the carrier structure 201, and the material moving driver 42 driving the longitudinal rod 421 to move in the horizontal direction, so that the transverse rod 422 abuts the carrier structure 201 and drives the carrier structure 201 to move to the cooling area 402.

[0046] It can be understood that the transverse rod 422 and the carrier structure 201 can be detachably connected, for example, a magnet is arranged on the transverse rod 422 and the carrier structure 201, and the two magnets are magnetically connected, so that the carrier structure 201 can be driven by the transverse rod 422 to move back and forth in the horizontal direction.

[0047] Referring to Figures 2 to 4 In one embodiment, the cooling structure further comprises a cooling pipe 41 for supplying cooling gas to the amorphous alloy located in the cooling area 402, and the cooling area 402 is located directly below the cooling pipe 41.

[0048] Optionally, the cooling gas can be low-temperature nitrogen, and the cooling pipe 41 sprays nitrogen towards the amorphous alloy in the cooling area 402, so that the amorphous alloy can be cooled. The cooling pipe 41 supplies cooling gas to the cooling area 402, achieving efficient cooling of the amorphous alloy. The cooling gas can quickly reduce the temperature of the amorphous alloy and prevent local overheating or supercooling during the cooling process due to uneven ambient temperature.

[0049] It can be understood that the amorphous alloy after hot pressing is located in the cooling area 402, and its temperature is not affected by the heating structure 202, avoiding the secondary heating of the amorphous alloy by the residual heat of the heating structure 202, solving the problem of easy crystallization of the amorphous alloy during the reheating process, and improving the cooling speed. In addition, the real-time temperature change of the amorphous alloy during the cooling process can be monitored, which can provide guidance for the improvement of the subsequent hot pressing process.

[0050] Referring to Figures 2 to 4 In one embodiment, the guide seat 40 is provided with a guide hole 401, the guide hole 401 is arranged on the same surface of the guide seat 40 as the cooling area 402, and the driving structure 203 is connected to the material loading structure 201 through the guide hole 401.

[0051] Optionally, the arrangement of the guide hole 401 provides good guiding support for the movement of the material loading structure 201, ensuring that the material loading structure 201 remains stable during vertical sliding, avoiding the situation that the amorphous alloy deviates or is unevenly stressed due to unstable displacement of the material loading structure 201 during hot pressing.

[0052] Referring to Figures 2 to 4 The cooling area 402 and the guide hole 401 are distributed on the same surface of the guide seat 40 and are arranged in a staggered manner, so that the target object can be directly slid into the cooling area 402 after completing hot pressing, avoiding unnecessary multi-step processing, simplifying the operation process, and improving the smoothness and efficiency of the entire hot pressing process.

[0053] Referring to Figures 2 to 4 In one embodiment, the guide seat 40 is further provided with a positioning cavity 403, the guide hole 401 is arranged at one end of the bottom of the positioning cavity 403, the cooling area 402 is located at the other end of the bottom of the positioning cavity 403, and the shape of the cavity wall at both ends of the positioning cavity 403 is adapted to the shape of the side surface of the material loading structure 201.

[0054] Optionally, the positioning cavity 403 is in the shape of a waist, the guide hole 401 and the cooling area 402 are located at opposite ends of the waist-shaped hole, by arranging the positioning cavity 403 in the guide seat 40, and the shape of the material loading structure 201 is circular, so that the material loading structure 201 can tightly fit the cavity wall of the positioning cavity 403 when located in the cooling area 402, enhancing the rapid positioning and stability of the material loading structure 201 after sliding into position. This precise adaptation reduces the shaking or deviation that may occur to the material loading structure 201, ensuring that the position of the material loading structure 201 remains unchanged during reciprocating sliding, thereby improving the accuracy of hot pressing and cooling.

[0055] Referring to Figures 2 to 4 In one embodiment, the driving structure 203 includes a lifting head 29 and a driving assembly 291 for driving the lifting head 29, the lifting head 29 penetrates the guide hole 401 and is connected to the material loading structure 201.

[0056] Optionally, the carrier structure 201 is connected by the lifting head 29, so that the carrier structure 201 can be accurately moved in the vertical direction. The lifting head 29 passes through the guide hole 401, which ensures the stability of the carrier structure 201 during hot pressing, and ensures uniform pressure distribution during hot pressing, avoiding deformation or performance degradation of the target object due to uneven pressure. The guide hole 401 also guides the movement of the lifting head 29.

[0057] Please refer to Figures 2 to 4 In one embodiment, the drive assembly 291 includes a lead screw connected to the lifting head 29, a lifting machine 34 connected to the lead screw, and a lifting drive 22 connected to the lifting machine 34. The lifting drive 22 can be a servo motor. The servo motor can provide a power source and can accurately start and stop.

[0058] The drive assembly 291 further includes a speed reducer, a shaft coupling 25, a guide rail mounting plate, an optical shaft locking assembly, a guide rail slider assembly, a lead screw sleeve locking assembly, and a lead screw sleeve fixing seat. The speed reducer is used to increase the load capacity of the output end. The speed reducer is mounted on the speed reducer mounting seat to fix the speed reducer. The shaft coupling 25 is used to connect the speed reducer and the lifting machine 34. The guide rail mounting plate, the optical shaft locking assembly, the guide rail slider assembly, the lead screw sleeve locking assembly, and the lead screw sleeve fixing seat are used to lock the rotational freedom of the lead screw sleeve around the Z-axis, prevent the pressure sensor 30 from failing, and ensure that the lifting head 29 only makes up-and-down reciprocating motion. The use of the guide rail slider assembly and the oil-free bushing ensures the straightness of the reciprocating motion of the lifting head 29 and the stability of the pressure output. The lifting of the lifting head 29 drives the forming die to complete the lifting or lowering. The pressure sensor 30 connected below the lifting head 29 can transmit the pressure signal of the pressure sensor 30 to the PLC in real time and display it on the touch screen.

[0059] Please refer to Figures 2 to 4 The pressure sensor 30 arranged on the lead screw sleeve can display the real pressure value acting on the forming die in real time. The lead screw sleeve locking assembly on the lead screw sleeve greatly increases the stability of the pressure and motion output with the assistance of the two side guide rails. The lifting machine 34 has four-stage motion, including fast motion when empty, medium-speed motion when the forming die is about to contact the heating structure 202, low-speed motion during hot pressing, and fast motion when the lifting machine 34 resets after hot pressing. The four-stage motion greatly reduces the hot pressing time and avoids high-speed impact on the forming die and the heating structure 202.

The relief hole 012 is provided with a sealing assembly, which comprises a dynamic sealing ring, a sealing ring support and a sealing flange, to ensure the vacuum degree when the lifting pressure head 29 reciprocates in the vacuum cavity 011.

[0062] The hot press shell 01 is a component for hot pressing, the volume of the vacuum cavity 011 is small, and the vacuum environment can be quickly realized. In addition, the hot press shell 01 is externally connected with various quick-change connectors, which are convenient for disassembly and assembly and maintenance.

[0063] The heating structure 202 is used for heat conduction heating of the amorphous alloy, which avoids heating of the whole hot press shell 01, so that the hot press shell 01 can still maintain a low temperature state after hot pressing, thereby preventing the residual heat of the hot press shell 01 from affecting the amorphous alloy.
