Specific Embodiments
[0019] The following further describes the specific embodiments of the present utility model with reference to the drawings.
[0020] As Figure 1-6As shown in the figure, a T-shaped nut forming device includes an installation table 1. The upper surface of the installation table 1 is evenly provided with forming grooves 3. The lower ends of the forming grooves 3 are open. Inside the installation table 1 and below the forming grooves 3, a bottom plate 4 is provided. The upper surface of the bottom plate 4 is evenly provided with bottom blocks 5 for closing the lower openings of the forming grooves 3. The inner bottom surface of the installation table 1 is evenly provided with central shafts 6. The central shafts 6 are slidably connected to the bottom plate 4 and the bottom blocks 5. Inside the installation table 1 and below the bottom plate 4, a cylinder 7 is provided. The output end of the cylinder 7 is fixedly connected to the bottom plate 4. The upper surface of the installation table 1 is provided with a top plate 8. A hydraulic cylinder 9 is provided on the top plate 8. The output end of the hydraulic cylinder 9 and below the top plate 8 is provided with a pressing plate 10. The lower end of the pressing plate 10 is evenly provided with pressing blocks 11 that cooperate with the forming grooves 3. A through groove 12 for accommodating the central shaft 6 is opened at the center of the pressing block 11.
[0021] When the bottom block 5 closes the lower opening of the forming groove 3, and a forming cavity for processing the T-shaped nut 2 is formed between the bottom block 5, the central shaft 6 and the forming groove 3, metal powder is put into all the forming grooves 3. The uppermost layer of the metal powder in the forming grooves 3 is flush with the upper opening of the forming grooves 3. After the metal powder is put in, the hydraulic cylinder 9 is started. The output end of the hydraulic cylinder 9 pushes the pressing plate 10 to move downward. The pressing plate 10 drives the pressing block 11 to move downward. When the pressing block 11 just enters the forming groove 3, the central shaft 6 enters the through groove 12 of the pressing block 11. Then, the metal powder in the forming cavity is continuously extruded through the pressing block 11. Through the continuous extrusion of the pressing block 11, the metal powder in the forming cavity is pressed into an integral shape. At this time, the initial blank of the T-shaped nut 2 is formed by the metal powder. Subsequently, sintering and threading and other processes still need to be carried out on it to complete the final processing of the T-shaped nut 2. In this process, it is only used for the initial blank forming of the T-shaped nut 2.
[0022] After the pressing of the T-shaped nut 2 is completed, the pressing block 11 is controlled to move upward through the hydraulic cylinder 9. Then, the bottom plate 4 is pushed upward through the cylinder 7. The bottom block 5 on the bottom plate 4 enters the forming groove 3 and pushes the T-shaped nut 2 in the forming groove 3 to move upward. When the T-shaped nut 2 completely moves out of the forming groove 3, the T-shaped nut 2 is also completely separated from the central shaft 6. At this time, all the T-shaped nuts 2 on the upper surface of the installation table 1 can be removed.
[0023] Further, an extension plate 13 is provided on one side of the upper surface of the mounting table 1. Lead screws 14 are symmetrically arranged on the mounting table 1 and the extension plate 13. A motor 15 for driving the rotation of the lead screws 14 is provided on one side of the extension plate 13. A scraper 16 is provided on the mounting table 1. The two ends of the scraper 16 are respectively threadedly connected to the lead screws 14. By controlling the two motors 15 to control the synchronous movement of the two lead screws 14, the scraper 16 can be driven to move linearly along the lead screws 14. By controlling the forward and reverse rotation of the lead screws 14, the reciprocating linear movement of the scraper 16 can be controlled. When the metal powder is placed on the upper surface of the mounting table 1, the metal powder can be pushed into the forming groove 3 by controlling the movement of the scraper 16, and the excess metal powder can be pushed to one side of the upper surface of the mounting table 1, so as to accurately press the T-shaped nut 2. And when the T-shaped nut 2 is pushed to the upper surface of the mounting table 1 through the bottom block 5, the T-shaped nut 2 can be completely pushed to one side of the upper surface of the mounting table 1 by the movement of the scraper 16, so as to improve the collection efficiency of the T-shaped nut 2. The material of the scraper 16 is nylon plastic to reduce the friction with the upper surface of the mounting table 1.
[0024] Further, a limiting plate 17 slidably connected to the central shaft 6 is provided inside the mounting table 1 and between the bottom plate 4 and the air cylinder 7. When the lower surface of the bottom plate 4 contacts the upper surface of the limiting plate 17, a forming cavity for processing the T-shaped nut 2 is formed between the bottom block 5, the central shaft 6 and the forming groove 3. The limiting plate 17 is used to support the bottom plate 4 and the bottom block 5 on the bottom plate 4, so as to avoid the air cylinder 7 bearing the pressure from the bottom plate 4 and the bottom block 5 for a long time. At the same time, the central shaft 6 can be slidably connected to the limiting plate 17, thereby improving the stability of the movement of the bottom plate 4 and avoiding the situation of tilting when the bottom plate 4 moves.
[0025] Further, a guide rod 18 is provided on the upper surface of the pressing plate 10. The guide rod 18 on the pressing plate 10 is slidably connected to the top plate 8 to improve the stability of the movement of the pressing plate 10 and avoid the situation of tilting when the pressing plate 10 moves.
[0026] Further, a chamfer is provided at the upper end of the central shaft 6 to facilitate the upper end of the central shaft 6 to enter the through groove 12 of the pressing block 11.
[0027] When the device is in use, multiple T-shaped nuts 2 can be extruded and formed at one time. Compared with the traditional stamping forming of a single bar stock, the production efficiency of the T-shaped nut 2 can be greatly improved, and the operation is also simpler. There is no need to place the bar stock one by one, and the use effect is good.
