[0002] Titanium alloys refer to various alloy metals made of titanium and other metals. Titanium is an important structural metal developed in the 1950s. Titanium alloys have high strength, good corrosion resistance, and high heat resistance. They are widely used in various industrial equipment. During the production and processing of titanium alloys, they are usually pre-formed into corresponding bar structures to facilitate subsequent transportation and handling.

[0003] However, in actual use, the bar sizes for different processing requirements of titanium alloys are also different. Therefore, it is necessary to change and adjust the forging dies of hot-rolled billets during processing. After processing, the corresponding bars need to be removed from the processing equipment and placed. However, since the bars of different sizes are of different lengths and thicknesses, there is a lack of efficient picking and conveying equipment. Manual handling is required to move and convey bars of different sizes, which is inefficient and dangerous. Utility Model Content

[0027] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0028] This utility model provides, for example Figure 1-5The forging die for hot-rolled titanium alloy bars shown includes a base plate 1, a top extrusion plate 2 on the top of the base plate 1, a bottom extrusion plate 101 slidably connected to the top of the base plate 1, a blocking post 3 at both ends of the top of the bottom extrusion plate 101, a lead screw 5 on one side of the top of the base plate 1 with reversed threads at both ends, a sliding rod 4 on the side of the lead screw 5 near the edge of the base plate 1, and a drive motor 6 at one end of the sliding rod 4; a fixing rod 301 is fixedly connected to the center of the end of the blocking post 3 away from the bottom extrusion plate 101, and a connecting plate 302 is sleeved on the outer wall of the fixing rod 301; a transmission plate 303 is fixedly connected to the side of the connecting plate 302 near the sliding rod 4; a drive gear 601 is fixedly connected to the power output end of the drive motor 6, and a driven gear 602 is rotatably connected to the end of the sliding rod 4 near the drive motor 6.

[0029] The two blocking posts 3 can be easily moved closer or further apart to adjust the spacing between the bottom extrusion plates 101, thereby adjusting the required processing length. During use, the first bolt 103 can be easily released to facilitate the disassembly and replacement of the bottom extrusion plate 101, allowing for the installation of different sized bottom extrusion plates. The top extrusion plate 2 can also be disassembled and replaced. Simultaneously, rotating the second bolt 304 releases the fixing rod 301, allowing for easy pulling of the fixing rod 301 to move the blocking posts 3, enabling disassembly, movement, or replacement of the blocking posts 3 to meet different processing needs. The drive motor 6 drives the driven gear 602 to rotate via the drive gear 601, which in turn drives the rotating gear 501 to rotate. The rotating gear 501 drives the lead screw 5 to rotate around the sliding rod 4, causing the transmission plate 303 to also rotate around the sliding rod 4. This, in turn, causes the transmission plate 303 to rotate and move the blocking posts 3 via the connecting plate 302 and the fixing rod 301, thus moving and placing the workpiece by rotating the blocking posts 3.

[0030] like Figure 1 , Figure 4 As shown, the top of the base plate 1 is provided with a sliding groove that is slidably connected to the bottom extrusion plate 101. The side of the base plate 1 near the lead screw 5 is internally threaded with a first bolt 103. One end of the first bolt 103 penetrates the interior of the base plate 1 and fits against the outer wall of the bottom extrusion plate 101. The first bolt 103 can be easily released to facilitate the disassembly and replacement of the bottom extrusion plate 101 and the installation of bottom extrusion plates of different sizes. The top extrusion plate 2 can also be disassembled and replaced. At the same time, by rotating the second bolt 304, the fixing rod 301 can be released, so that the fixing rod 301 can be easily pulled to move the blocking column 3, thereby realizing the disassembly, movement or replacement of the blocking column 3 to meet different processing requirements.

[0031] like Figure 4 , Figure 5 As shown, the top of the bottom extrusion plate 101 and the bottom of the top extrusion plate 2 are both provided with arc-shaped grooves, and the diameter of the blocking column 3 corresponds to the diameter of the arc-shaped groove. The bottom of the connecting plate 302 is threaded with a second bolt 304. One end of the second bolt 304 passes through the interior of the connecting plate 302 and is in contact with the fixing rod 301. The outer walls of both ends of the lead screw 5 are threaded to the transmission plate 303. The two ends of the sliding rod 4 are slidably connected to the transmission plate 303. The top of the transmission plate 303 near the end of the lead screw 5 is threaded with a fourth bolt 502, and the fourth bolt 502 passes through the interior of the transmission plate 303 and is in contact with the lead screw 5. The rotating gear 501 drives the lead screw 5 to rotate around the sliding rod 4, which enables the transmission plate 303 to also rotate around the sliding rod 4. In turn, the transmission plate 303 drives the blocking column 3 to rotate and move through the connecting plate 302 and the fixing rod 301. Thus, the workpiece is moved and placed by rotating the blocking column 3, without the need for manual handling.

[0032] like Figure 1 , Figure 5 As shown, a rotating gear 501 is fixedly connected to one end of the lead screw 5 near the drive motor 6. The bottom of the drive motor 6 is fixed to the top of the base plate 1. The top of the drive gear 601 meshes with the driven gear 602, and one side of the driven gear 602 meshes with the rotating gear 501. The lead screw 5 is pressed and fixed by the fourth bolt 502, so that the lead screw 5 is fixed to the transmission plate 303. At the same time, since the lead screw 5 is fixed, the rotating gear 501 is also fixed, so that the rotating gear 501 and the transmission plate 303 remain fixed to each other. When the drive motor 6 drives the driven gear 602 to rotate through the drive gear 601, the driven gear 602 can drive the rotating gear 501 to rotate, and the rotating gear 501 drives the lead screw 5 to rotate around the sliding rod 4.

[0033] like Figure 2 , Figure 4 As shown, a fixing block 401 is sleeved at the center of the sliding rod 4, and the fixing block 401 is fixed to the top of the base plate 1. A third bolt 402 is threadedly connected to the top of the fixing block 401, and one end of the third bolt 402 passes through the interior of the fixing block 401 and fits against the sliding rod 4. The workpiece is clamped and squeezed by the blocking posts 3 at both ends. Then, the hydraulic push rod 201 is activated to drive the top pressing plate 2 to move to the top, release the obstruction of the workpiece, and conveniently rotate the third bolt 402 to release the fixation of the sliding rod 4.

[0034] like Figure 1 , Figure 2As shown, a top plate 202 is provided on the top of the top extrusion plate 2. Multiple hydraulic push rods 201 are fixedly fixed inside the top plate 202. The bottom protruding ends of the hydraulic push rods 201 are fixed to the top of the top extrusion plate 2. A fixing plate 102 is fixedly connected to the bottom of the side of the top plate 202 away from the sliding rod 4. The top of the bottom plate 1 is fixedly connected to the top plate 202 through the fixing plate 102. The side of the fixing plate 102 is slidably connected to the top extrusion plate 2. During processing, the hydraulic push rods 201 are activated to drive the top extrusion plate 2 to move along the fixing plate 102 to the bottom, thereby realizing the processing of the workpiece.

[0035] In use, the blank to be processed can be easily placed on the top of the bottom extrusion plate 101. Then, the fourth bolt 502 is released, and the drive motor 6 is started. The drive motor 6 drives the driven gear 602 to rotate via the drive gear 601. This causes the driven gear 602 to drive the lead screw 5 to rotate via the rotating gear 501. Since the lead screw 5 is threadedly connected to the transmission plate 303, and the transmission plate 303 is slidably connected to the sliding rod 4, the transmission plate 303 cannot rotate along with the lead screw 5. Instead, the transmission plate 303 slides along the sliding rod 4. The transmission plate 303 then drives the fixed rod 301 to move via the connecting plate 302, which in turn moves the blocking post 3. Simultaneously, because the lead screw 5... The threads at both ends are reversed, which allows the two blocking posts 3 to be moved closer or further apart, thereby adjusting the spacing between the bottom extrusion plates 101 and thus adjusting the required processing length. In use, the first bolt 103 can be easily released to facilitate the disassembly and replacement of the bottom extrusion plate 101, allowing for the installation of different sized bottom extrusion plates. The top extrusion plate 2 can also be disassembled and replaced. Simultaneously, by rotating the second bolt 304, the fixing rod 301 can be released, allowing the fixing rod 301 to be pulled to move the blocking posts 3, enabling the disassembly, movement, or replacement of the blocking posts 3 to meet different processing needs. During processing, the hydraulic push rod 201 is activated to move the top extrusion plate 2 along the fixing plate 102 to the bottom, thereby processing the workpiece.

[0036] When processing is complete or the workpiece needs to be moved, the workpiece can be clamped and squeezed by the blocking posts 3 at both ends. Then, the hydraulic push rod 201 is activated to move the top squeezing plate 2 to the top, releasing the obstruction of the workpiece. The third bolt 402 can then be rotated to release the fixation of the sliding rod 4. At the same time, the fourth bolt 502 squeezes and fixes the lead screw 5, so that the lead screw 5 and the transmission plate 303 are fixed to each other. Since the lead screw 5 is fixed, the rotating gear 501 is also fixed, so that the rotating gear 501 and the transmission plate 303 are fixed to each other. The components are kept fixed to each other. When the drive motor 6 drives the driven gear 602 to rotate through the drive gear 601, the driven gear 602 drives the rotating gear 501 to rotate. The rotating gear 501 drives the lead screw 5 to rotate around the sliding rod 4, which causes the transmission plate 303 to also rotate around the sliding rod 4. The transmission plate 303 then drives the blocking column 3 to rotate and move through the connecting plate 302 and the fixed rod 301. The rotating blocking column 3 moves and places the workpiece without the need for manual handling, which is very convenient.

Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
