Description

Technical Field

[0001] This invention relates to the technical field of titanium alloy material forming processes, and in particular to a titanium alloy material stacking forming device and a titanium alloy material stacking forming process. Background Technology

[0002] Titanium alloys possess excellent properties such as high strength, good corrosion resistance, and non-magnetic properties, making them widely used in aerospace, chemical, and electronic equipment fields. However, existing titanium alloys have relatively low hardness, resulting in poor wear resistance and insufficient resistance to fatigue fracture. Fatigue fracture is the most common failure mode in workpieces formed from titanium alloys. Unlike static load fracture, materials exhibiting brittleness or toughness under static loads do not undergo significant plastic deformation during fatigue fracture; the fracture occurs suddenly, making it extremely dangerous and prone to serious accidents. This is especially true for components subjected to alternating stresses, where the stress is often below the material's yield strength or even elastic limit, yet fatigue fracture still easily occurs.

[0003] Based on this, Chinese patent CN115971385A discloses a titanium alloy material and its forging method.

[0004] Regarding applications and titanium alloy products, the forging method of the titanium alloy material includes the following steps: pre-treating the titanium alloy billet at 30°C to 70°C below the Tβ phase transformation point, followed by cooling; wherein, the pre-treatment time... h is the minimum cross-sectional dimension of the titanium alloy billet, and the unit of h is mm; the cooled titanium alloy billet is held at 60°C to 100°C below the Tβ phase transformation point for a specified time. Where h is the thickness of the titanium alloy billet, and the unit of h is mm; the titanium alloy billet after heat preservation is precision forged, and the forging speed of each pass is ≤3.5m / min. The above forging method for titanium alloy materials can effectively increase the primary α phase content of titanium alloy materials, thereby effectively ensuring the fatigue performance of titanium alloy materials.

[0005] Furthermore, in the sheet metal forming process, the sheet metal usually needs to be heated and softened before being fed into the forming machine for hot pressing. Because the hot pressing process is relatively fast, while the heating and softening process takes a long time, after one sheet metal is hot-pressed, it is necessary to wait for the next sheet metal to be heated and softened. Therefore, it is evident that the forming efficiency of current forming machines is relatively low, and continuous hot pressing forming cannot be achieved. Based on this, another Chinese patent, CN110524849B, discloses a composite stacking forming machine and a sheet metal forming method. This forming machine includes a first frame, a second frame, and a forming frame. The first frame houses a first feeding mechanism and a second feeding mechanism, while the second frame houses a first heating mechanism and a second heating mechanism. Two feeding stations are located on one side of the bottom of the first frame. Inside the first frame, a first feeding platform and a second feeding platform are also installed, with a height difference between them. A first transport system connects the first frame and the forming frame, passing through the first heating mechanism. A second transport system also connects the first frame and the forming frame, passing through the second heating mechanism. When using this sheet metal forming machine to form sheets, two sheets can enter the forming machine sequentially for hot pressing, fully utilizing the waiting time after the previous sheet metal forming and improving the sheet metal forming efficiency.

[0006] However, the existing hardware mold industry lacks a stacking forming process for manufacturing titanium alloy products. Specifically, while current technologies have optimized the preparation and forging processes of titanium alloy materials, the hardware mold industry is still in a state of technological reserve for sheet metal titanium alloy materials. Although processing schemes for heating, pressurizing, and stacking sheet metal have been revealed, they are not entirely suitable for the forming and processing of all sheet metal titanium alloy materials.

[0040] Please refer to the following: Figures 1 to 6The titanium alloy material stacking forming device of the present invention includes: an upper part 1 of the actuating device and a lower part 2 of the actuating device, wherein the upper part 1 and the lower part 2 of the actuating device are arranged to open and close relative to each other. The upper part 1 of the actuating device is provided with an upper mold base 101, a fixed pad 102, a fixed plate 103, a pressure plate 104, a plurality of pressure springs 105, side inserts 106, a central insert 107, and a guide sleeve 108; the fixed pad 102 is connected to the lower part of the upper mold base 101; the fixed plate 103 is connected to the lower part of the fixed pad 102. The pressure plate 104 is disposed below the fixed plate 103, and the plurality of pressure springs 105 are respectively connected to the pressure plate 104 and the fixed plate 103. Two side inserts 106 are respectively disposed on two sides of the pressure plate 104; the central insert 107 is disposed between the two side inserts 106 on the adjacent side of the pressure plate 104. Several guide sleeves 108 are respectively disposed below both ends of the upper mold base 101. The lower part 2 of the actuation device is provided with a lower mold base 201, a lower mold pad 202, a material groove positioning part 203, a side stacking slider 204, a central limiting moving block 205, and several guide pillars 206; the lower mold pad 202 is connected above the lower mold base 201; the material groove positioning part 203 is disposed on the lower mold pad 202. Two side stacking sliders 204 are respectively disposed on both sides of the material groove positioning part 203. Each side stacking slider 204 is movably connected to the lower mold pad 202. Each side inserter 106 drives one side stacking slider 204. The central limiting block 205 is disposed on the side of the material groove positioning part 203. The central limiting block 205 is disposed between the two side stacking sliders 204 and is movably connected to the lower mold pad 202. Each central inserter 107 drives one central limiting block 205. A plurality of guide posts 206 are respectively disposed above both ends of the lower mold base 201. Each guide post 206 is movably connected to one guide sleeve 108.

[0041] Specifically, when the upper part 1 of the actuating device is connected to an external power mechanism, the upper part 1 of the actuating device can move from above the lower part 2 of the actuating device to approach the lower part 2 of the actuating device. Thus, when the titanium alloy material stacking forming device of the present invention is in operation, the user can first place the titanium alloy raw material on the preset placement position of the material groove positioning part 203; and the guide sleeve 108 can be correspondingly matched with a guide post 206 so that the upper part 1 of the actuating device can be accurately matched with the lower part 2 of the actuating device. In addition, when the pressure plate 104 follows the upper mold base 101, the fixed pad 102 and the fixed plate 103 downward, it first abuts against the upper part of the titanium alloy raw material and presses the titanium alloy raw material into the material groove positioning part 203; then, when the middle insert 107 moves downward, it drives the middle limiting moving block 205 to press and limit the material from the side of the material groove positioning part 203. Next, the two side inserts 106 located at both ends of the material trough positioning part 203 simultaneously drive one side stacking slider 204, causing the side stacking slider 204 to move towards the titanium alloy raw material, thereby completing the stacking and forming action of the titanium alloy raw material. More specifically, when the pressure plate 104 descends to abut against the titanium alloy raw material, the pressure spring 105 provides elasticity to the pressure plate 104 to achieve the purpose of pressing the material. After completing one stacking and forming action, the upper part 1 of the action device is reset under the drive of the external power mechanism, and the other components are also reset, and the user can take the finished product from the material trough positioning part 203. It can be seen that the titanium alloy material stacking and forming device of the present invention can automatically press the titanium alloy raw material and simultaneously perform stacking and forming processing actions on the raw material. This process does not require the participation of actuation mechanisms such as cylinders or hydraulic cylinders, but the components directly perform mechanical reciprocating actions, which significantly improves the forming and processing efficiency of titanium alloy materials.

[0042] Furthermore, the upper part 1 of the actuating device is provided with limit posts 109, and two limit posts 109 are respectively disposed at both ends of the upper mold base 101, with each limit post 109 fixedly connected to the lower part of the upper mold base 101. The lower part 2 of the actuating device is provided with limit blocks 207, and two limit blocks 207 are respectively disposed at both ends of the lower mold base 201 corresponding to one limit post 109. Specifically, when the limit post 109 touches the limit block 207, the upper part 1 of the actuating device reaches its downward stop point. Afterward, the upper part 1 of the actuating device will move upward to reset under the drive of an external actuating mechanism.

[0043] Furthermore, the lower part 2 of the actuating device is provided with a storage tank 208, a discharge pin 209, and a discharge spring 210. The storage tank 208 is located between the material trough positioning part 203 and the central limiting moving block 205. A plurality of discharge pins 209 are evenly and movably arranged in the storage tank 208. The lower part of each discharge pin 209 is connected to a discharge spring 210, and each discharge spring 210 is connected to the lower mold pad 202. Specifically, the user can place the titanium alloy raw material to be processed in the storage tank 208. At this time, the bottom of the titanium alloy raw material is supported by the discharge pin 209, and the top of the titanium alloy raw material extends out of the storage tank 208. When the stacking and forming process begins, when the pressure plate 104 moves downward, its bottom presses the titanium alloy raw material into the storage tank 208, at which time the discharge spring 210 is compressed. After the titanium alloy raw material completes the stacking and forming process, the compressed unloading spring 210 can automatically return to its original position and extend, thereby lifting the unloading pin 209 and pushing the titanium alloy raw material out of the storage tank 208, so that the user can collect the material after the stacking and forming process, thus speeding up the stacking production process.

[0044] Furthermore, each of the side inserters 106 is provided with a plurality of inserter inclined surfaces 106a; each inserter inclined surface 106a is sequentially disposed at the lower end of the side inserter 106. Specifically, each inserter inclined surface 106a has a different inclination. Furthermore, each of the side stacking sliders 204 is provided with a plurality of driving inclined surfaces 204a, the plurality of driving inclined surfaces 204a being sequentially disposed at the outer end of the side stacking slider 204, and each driving inclined surface 204a being movably connected to one inserter inclined surface 106a. Specifically, each of the driving inclined surfaces 204a is provided with a different inclination angle and is matched and connected to a corresponding inserting inclined surface 106a. This allows the side inserting blade 106 to descend until it abuts the outer end of the side stacking slider 204. The abutment and matching of the inserting blade inclined surface 106a and the driving inclined surface 204a then causes the side stacking slider 204 to perform different actions, such as pre-positioning, clamping, and stacking processing. Similarly, the central inserting blade 107 and the central limiting moving block 205 can also be provided with similar components.

[0045] Furthermore, the lower part 2 of the actuation device is also provided with a slide rail 211; one slide rail 211 is provided on each side of each of the side stacking sliders 204, and each slide rail 211 is disposed on the lower mold pad 202. Specifically, the slide rail 211 can serve as a sliding guide rail for the side stacking sliders 204.

[0046] Furthermore, the lower part 2 of the actuation device is also provided with a lower mold pad 212; a plurality of the lower mold pads 212 are evenly distributed below the lower mold base 201.

[0047] Furthermore, a punch press actuation mechanism 3 and a punch press body 4 are disposed on the upper part 1 of the actuation device; the punch press actuation mechanism 3 is connected to the upper part 1 of the actuation device, and the punch press actuation mechanism 3 is connected to the punch press body 4. In addition, a worktable 5 is disposed below the lower part 2 of the actuation device; the lower part 2 of the actuation device is connected to the worktable 5, and the worktable 5 is connected to the punch press body. Specifically, the punch press body 4 can control the punch press actuation mechanism 3 to move the upper part 1 of the actuation device closer to or further away from the lower part 2 of the actuation device.

Specifically, titanium alloy materials with stacking processing can be placed on the heating placement rack 7, and the heating working part 8 can perform targeted heating on a localized area of ​​the titanium alloy material; and the temperature controller 9 can control the heating time and heating temperature and other process parameters of the titanium alloy material.

[0049] For further details, please refer to Figure 7 A titanium alloy sheet 10; its main body is provided with several stacked parts 1001.

[0050] Furthermore, a titanium alloy material stacking forming process includes the following steps:

The unloading spring 210 provided below the unloading pin 209 and the pressure spring 105 provided between the fixed plate 103 and the pressure plate 104 are compressed at the same time.

[0054] S4: The middle inserter 107 drives the middle limiting block 205 to move towards the material groove positioning part 203 to limit the side of the titanium alloy plate 10; the two side inserters 106 drive the two side stacking sliders 204 to move towards the material groove positioning part 203 to make each side stacking slider 204 move towards the material groove positioning part 203 to process the two ends of the titanium alloy plate 10 to obtain the stacking part 1001.

[0055] S5: When the limit post 109 moves down to the top of the limit block 207, the punch press body 4 controls the punch press action mechanism 3 to drive the upper part 1 of the action device to move upward and reset; the pressure spring 105 extends to push the pressure plate 104 to reset, and the unloading spring 210 extends to push the unloading pin 209 to move upward and reset.
