Description

Technical Field

[0001] The utility model relates to the technical field of titanium alloy blades, in particular to a titanium alloy blade forming device. Background Art

[0002] Titanium is an important structural metal developed in the 1950s. Titanium alloys are widely used in various fields due to their high strength, good corrosion resistance and high heat resistance. Many countries in the world have recognized the importance of titanium alloy materials, and have successively conducted research and development on them, and have obtained practical applications. In the 1950s and 1960s, the main focus was on the development of high-temperature titanium alloys for aircraft engines and structural titanium alloys for fuselages. In the 1970s, a batch of corrosion-resistant titanium alloys were developed. Since the 1980s, corrosion-resistant titanium alloys and high-strength titanium alloys have been further developed. Titanium alloys are mainly used to make aircraft engine compressor components, followed by rockets, missiles and high-speed aircraft structural parts. Titanium alloy blades are processed and formed from titanium and its alloy materials. They have the advantages of high yield strength, corrosion resistance and wear resistance. They are mainly used as important components of impellers for engines, aerospace and other equipment, and are widely used in the processing of automobiles, motorcycles, internal combustion engines, submarines and aircraft blades.

[0003] After the titanium alloy blades are formed in the mold, they are usually tightly attached to the inner wall of the mold. Excessive force may be required to remove the blades, which may cause scratches, deformation or damage to the blade surface. Especially for titanium alloy blades with high surface requirements, such damage may affect their performance and appearance, and may also cause mold wear, scratches or cracks, thereby reducing the life of the mold and increasing the cost of mold maintenance and replacement. In view of the above problems, a titanium alloy blade forming device is proposed to solve them. Utility Model Content

[0019] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are only examples, and those skilled in the art may think of other obvious variations.

[0020] Reference Figure 1-4 As shown, a titanium alloy blade forming device comprises a workbench 1, support plates 2 are fixedly connected to the front and rear sides of the middle part of the upper surface of the workbench 1, an ejection assembly 3 is arranged between the two support plates 2, the ejection assembly 3 comprises a base plate 301, the base plate 301 is fixedly connected to the upper surface of the workbench 1, sleeves 302 are fixedly connected at the four corners of the upper surface of the base plate 301, a lifting column 303 is slidably connected inside the sleeve 302, an ejection block 304 is fixedly connected to the top of the lifting column 303, a buffer spring 305 is arranged inside the sleeve 302 and at the bottom of the lifting column 303, supports 307 are fixedly connected to the left and right sides of the upper surface of the workbench 1 and the front support plate 2, connecting rods 309 are rotatably connected to the upper ends of the two supports 307, connecting columns 308 are fixedly connected to the left and right sides of the base plate 301, and second sliding grooves 310 are penetrated by the two connecting rods 309 near one end of the connecting column 308, and the connecting column 308 is slidably connected inside the second sliding groove 310.

[0021] Specifically, the inner sides of the two support plates 2 are each provided with a first sliding groove 12, and the middle parts of the front and rear sides of the base plate 301 are fixedly connected with sliding blocks 306, and the sliding blocks 306 are slidably connected inside the first sliding groove 12. The cooperation between the sliding blocks 306 and the first sliding groove 12 enables the ejection block 304 to be more precise when performing the ejection action, thereby preventing the ejection action from being stuck due to shaking.

[0022] Specifically, guide columns 5 are fixedly connected at the four corners of the upper surface of the workbench 1, mounting plates 6 are fixedly connected to the tops of the four guide columns 5, and a hydraulic press 7 is fixedly installed in the middle of the upper surface of the mounting plate 6. The hydraulic press 7 can provide sufficient pressure and accurately control parameters such as speed, force and time by controlling the parameters of the hydraulic system.

[0023] Specifically, the output end of the hydraulic press 7 passes through the upper surface of the mounting plate 6 and is fixedly connected to a sliding plate 8. The four corners of the sliding plate 8 are respectively slidably connected to four guide columns 5. Guide sleeves are provided at the four corners of the sliding plate 8 to improve the smoothness during movement and the accuracy during mold closing.

[0024] Specifically, an upper mold 9 is fixedly connected to the bottom of the sliding plate 8, and a lower mold 4 is fixedly connected to the top of the two support plates 2. A pouring port 10 is opened on the right side of the upper mold 9 and the lower mold 4. A pouring pipe 11 is fixedly connected to the inside of the pouring port 10 on the lower mold 4. Further, by optimizing the structure and surface coating of the upper mold 9 and the lower mold 4, the adhesion between the blade and the inner wall of the mold can be reduced, so that the blade can be ejected more easily.

[0025] Optionally, a pressing rod 311 is fixedly connected between the two connecting rods 309 away from the connecting column 308. The pressing rod 311 can be replaced with a cylinder or hydraulic form to replace the manual pressing method, so that the device can be more automated.

[0026] Working principle: When in use, the hydraulic press 7 pushes the sliding plate 8 to move along the guide column 5, and the sliding plate 8 drives the upper mold 9 to close the mold with the lower mold 4 to form a mold cavity, and then injects material into the mold cavity through the casting pipe 11. After the blade is cooled and formed, the hydraulic press 7 drives the upper mold 9 to leave the lower mold 4 to open the mold, and then presses the lower pressure rod 311 downward to make the connecting rod 309 rotate around the support 307. The end of the connecting rod 309 away from the lower pressure rod 311 will be pushed up, and the base plate 301 is driven to move upward through the connecting column 308. The sleeves 302 at the four corners of the base plate 301 follow the movement, so that the ejection block 304 inside the sleeve 302 ejects the blade formed in the lower mold 4, which can reduce the direct contact of the operator with the blade, reduce the probability of injury, and improve the safety of the production site.
