Description

Technical Field

[0001] The utility model relates to the technical field of forming special-shaped tooth blades, and specifically relates to a device for forming special-shaped tooth blades. Background Art

[0002] The blade in the existing hair clipper has been optimized and improved in structure. An irregular pointed tooth assembly composed of multiple bifurcated pointed tooth sub-units is adopted to replace the existing "|" shape. Therefore, it can provide a more efficient trimming function, trim more cleanly, and have a better trimming experience. The irregular pointed teeth are in shapes such as "Y" shape, "U" shape, and "V" shape. Due to the change in the shape of the pointed teeth, the conventional tooth opening method is difficult to process. Therefore, when producing this kind of special-shaped tooth blade, an extrusion molding technology is often used, that is, a certain amount of metal powder is added into the mold cavity, and a certain pressure is applied to make it form a specific special-shaped tooth blade shape, and then it is solidified by sintering. When the existing molding device is in use, it requires the staff to manually add metal powder into the molding cavity, which is not only cumbersome in operation but also low in efficiency, and it is difficult to meet the usage requirements.

[0018] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings.

[0019] like Figure 1-6 As shown, a non-standard toothed blade forming device includes a worktable 1, a forming cavity 2 on the worktable 1, a base plate 3 inside the forming cavity 2, a support plate 4 at the lower end of the base plate 3, the lower end of the support plate 4 penetrating the forming cavity 2 and extending below the forming cavity 2, a partition plate 5 below the worktable 1, an electric push rod 6 for controlling the movement of the support plate 4 on the partition plate 5, a column 7 on the upper surface of the worktable 1, a top plate 8 on the column 7, a first cylinder 9 on the top plate 8, the output end of the first cylinder 9 penetrating the top plate 8 and connecting to a fixed plate 10, the fixed plate 10 slidably connected to the column 7, a forming mold 11 at the lower end of the fixed plate 10, and a receiving frame 12 slidably connected to the upper surface of the worktable 1. A storage bin 13 is provided on the side, and a flip-up sealing plate 14 is provided on the storage bin 13. A second cylinder 15 for controlling the movement of the receiving frame 12 is provided on the upper surface of the storage bin 13. A support frame 16 is provided on the upper surface of the workbench 1. A vertical rod 17 is provided on the lower surface of the support frame 16. A baffle 18 is provided at the lower end of the vertical rod 17. A cover plate 19 is also included. The cover plate 19 is slidably connected to the vertical rod 17. A spring 20 is sleeved on the vertical rod 17. The spring 20 is located above the cover plate 19. A suction device 21 is provided on the storage bin 13. The suction device 21 has a suction pipe 22 and a discharge pipe 23. The discharge pipe 23 is located inside the storage bin 13 and is fixed on the support frame 16. A through hole for the discharge pipe 23 is opened on the cover plate 19.

[0020] When processing irregular toothed blades, first open the sealing plate 14 and put metal powder into the storage box 13. Then start the suction device 21. The suction device 21 draws the metal powder in the storage box 13 into the receiving frame 12 through the suction pipe 22 and the discharge pipe 23. The cover plate 19 can confine the metal powder in the receiving frame 12. When the receiving frame 12 contains an appropriate amount of metal powder, the suction device 21 stops working. Then start the second cylinder 15. The second cylinder 15 pushes the receiving frame 12 on the worktable. As the receiving frame 12 moves upward, it passes through the forming cavity 2. When it passes the forming cavity 2, the metal powder inside the receiving frame 12 falls into the forming cavity 2 under the influence of gravity. After the receiving frame 12 has completely passed through the forming cavity 2, the second cylinder 15 controls the receiving frame 12 to reset. During the reset process, the receiving frame 12 smooths out the metal powder inside the forming cavity 2. After the receiving frame 12 has completed its reset, the first cylinder 9 is activated, causing the fixing plate 10 and the forming mold 11 to move downwards. The forming mold 11 moves into the forming cavity 2 and squeezes the metal powder inside the forming cavity 2, causing the shaped toothed blade inside the forming cavity 2 to be extruded and shaped. After the shaped toothed blade is extruded and shaped, the first cylinder 9 drives the fixed plate 10 and the forming mold 11 to move upward. Then the electric push rod 6 is activated, and the electric push rod 6 pushes the support plate 4 and the bottom plate 3 to move upward. When the upper surface of the bottom plate 3 is on the same plane as the upper surface of the worktable 1, it remains in that position. Then, when the receiving frame 12 continues to transport metal powder into the forming cavity 2, the receiving frame 12 will first push away the shaped toothed blade on the bottom plate 3. After the shaped toothed blade is completely pushed away from the bottom plate 3, the electric push rod 6 controls the support plate 4 and the bottom plate 3 to move downward. The metal powder in the receiving frame 12 continues to fall into the forming cavity 2 under the action of gravity. When the receiving frame 12 has completely passed through the forming cavity 2, the second cylinder 15 continues to control the receiving frame 12 to reset, so that metal powder can continue to be fed into the receiving frame 12.

[0021] Furthermore, a guide rod 24 is provided on the workbench 1 above the partition 5. The support plate 4 is slidably connected to the guide rod 24. The guide rod 24 can improve the stability of the support plate 4 and the base plate 3 when they move up and down, and prevent the base plate 3 and the support plate 4 from becoming unstable when they move.

[0022] Furthermore, an extension tube 25 is provided on the support plate 4, and the guide rod 24 is slidably connected to the extension tube 25, which increases the contact area between the support plate 4 and the guide rod 24 and further improves the stability of the fit.

[0023] Furthermore, the interior of the storage bin 13 is provided with an inclined surface. When the metal powder in the storage bin 13 is consumed, the metal powder located at the top can move along the inclined surface to a position close to the lower end of the extraction pipe 22, making it easier to extract the metal powder in the storage bin 13.

[0024] Furthermore, the lower side of the end of the cover plate 19 near the molding cavity 2 is provided with a rounded corner. During the resetting process, the receiving frame 12 will contact the rounded corner at the lower end of the cover plate 19, pushing the cover plate 19 to move upward and compressing the spring 20 on the vertical rod 17, thereby improving the tightness and stability of the fit between the cover plate 19 and the receiving frame 12. When the cover plate 19 is in the lowest position, the receiving frame 12 can stably enter under the cover plate 19 and push the cover plate 19 to move upward a certain distance.
