Detailed implementation manners
[0027] In order to make the objectives, technical solutions and advantages of the present utility model clearer and more understandable, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.
[0028] In one embodiment, as Figures 1 - 8As shown in the figure, a high-frequency welding magnetic rod pressing die includes a die frame 11. Inside the die frame 11, a forming bottom frame 12 is installed. At the upper end of the forming bottom frame 12, a supporting platform plate 15 is fixedly installed. Inside the forming bottom frame 12, a first fixing plate 13 and a second fixing plate 14 are fixedly installed. The second fixing plate 14 is located above the first fixing plate 13. In the middle position at the upper end of the first fixing plate 13, a core 16 is fixedly installed. The upper end of the core 16 penetrates through the second fixing plate 14 and extends to the upper surface of the supporting platform plate 15. In the middle position at the upper end of the second fixing plate 14, a fixing part 17 is fixedly installed. The upper end of the fixing part 17 is fixedly connected to the lower end of the supporting platform plate 15. The space between the core 16 and the fixing part 17 is a material cavity. On both the front and rear sides of the supporting platform plate 15, side plates are fixedly installed. A chute 23 is opened at the front end of the side plate. On the upper ends of the two side plates, a feeding rack 24 is fixedly installed. The upper end of the feeding rack 24 is communicated with a feeding pipe. A blanking structure is arranged between the supporting platform plate 15 and the feeding rack 24 for injecting pressing powder into the material cavity. A pressing structure is arranged inside the forming bottom frame 12 and at the upper end of the die frame 11 for forming the pressing powder into a blank. Knocking structures are arranged on both the front and rear sides of the feeding rack 24 for preventing the blanking structure from being unable to operate normally due to blockage by the pressing powder.
[0029] In this embodiment, the staff transports the pressing powder to the inside of the blanking structure through the feeding pipe. The blanking structure injects the pressing powder into the material cavity. Then, the staff uses the pressing structure to form the pressing powder into a blank. When the blanking structure injects the pressing powder into the material cavity, the knocking structures continuously knock on the outer wall of the blanking structure, so that the pressing powder inside the blanking structure vibrates continuously, preventing the blanking structure from being unable to operate normally due to blockage by the pressing powder.
[0030] In one embodiment, as Figure 7 shown, the blanking structure includes a material bin 26. The material bin 26 is slidably installed at the upper end of the supporting platform plate 15. An upper feeding hole is opened at the upper end of the material bin 26. A lower feeding hole is opened at the lower end of the material bin 26. Sliders matching the chute 23 are fixedly installed at both the front and rear ends of the material bin 26. The upper end of the material bin 26 is slidably attached to the lower end of the feeding rack 24. The inside of the material bin 26 is communicated with the feeding pipe. The left end of the material bin 26 is fixedly connected to the telescopic end of a second electric push rod 25. A pushing block 27 is fixedly installed at the bottom of the right end of the material bin 26. A sealing component is installed inside the pushing block 27.
[0031] The blanking hole is sealed by a sealing component. Subsequently, the compacting powder is conveyed into the interior of the bin 26 through a feed pipe. The bin 26 is pushed by the second electric push rod 25 to the upper end of the material cavity. The sealing component stops the blanking hole for sealing, and the compacting powder inside the bin 26 flows into the interior of the material cavity. During the feeding process of the bin 26 to the material cavity, the push block 27 can push the compacted blank to the outside of the support platform plate 15, facilitating the operation of the staff and improving production efficiency.
[0032] In one embodiment, as Figure 7 shown, the sealing component includes a third electric push rod 28, and the third electric push rod 28 is installed in a sealing cavity formed inside the push block 27. The telescopic end of the third electric push rod 28 is fixedly connected to a sealing block 29, and the lower end of the sealing block 29 is in close fit with the upper end of the blanking hole.
[0033] The third electric push rod 28 is used to push the sealing block 29 to move to the upper end of the blanking hole. Since the lower end of the sealing block 29 is in close fit with the upper end of the blanking hole, it is possible to prevent the compacting powder from flowing into the upper end of the support platform plate 15 through the blanking hole during the movement of the bin 26, thereby avoiding waste of the compacting powder and affecting the subsequent compacting work.
[0034] In one embodiment, as Figure 3 and Figure 5 shown, the compacting structure includes a first electric push rod 18, and the first electric push rod 18 is installed inside the forming bottom frame 12. The forming bottom frame 12 is located inside the mold frame 11. The telescopic end of the first electric push rod 18 is fixedly connected to a first push plate 19. A plurality of push rods 20 are fixedly connected to the upper end of the first push plate 19. The plurality of push rods 20 slide through to the upper end of the first fixing plate 13 and are fixedly connected to the lower end of a second push plate 21. A lower compacting member 22 matching the material cavity is fixedly installed at the middle position of the upper end of the second push plate 21. The upper end of the lower compacting member 22 penetrates through the second fixing plate 14 and extends to the upper surface of the support platform plate 15. An upper compacting component is installed at the upper end of the mold frame 11.
[0035] The compacting powder enters the interior of the material cavity. Through the mutual cooperation of the upper compacting component and the lower compacting member 22, the compacting powder is formed into a blank. Subsequently, the first electric push rod 18 is used to push the lower compacting member 22 upward, thereby ejecting the blank from the material cavity, eliminating the need for manual blank taking and improving production efficiency.
[0036] In one embodiment, as Figure 1 and Figure 8 shown, the upper compacting component includes a fourth electric push rod 37, and the fourth electric push rod 37 is installed at the middle position of the upper end of the mold frame 11. The telescopic end of the fourth electric push rod 37 extends into the interior of the mold frame 11 and is fixedly connected to an upper compacting member 38 matching the lower compacting member 22.
[0037] The compacted powder enters the interior of the material cavity. The fourth electric push rod 37 is used to push the upper compacting part 38 downward. The upper compacting part 38 enters the interior of the material cavity. The upper compacting part 38 and the lower compacting part 22 cooperate with each other, so that the compacted powder forms a billet, which is convenient for the staff to operate.
[0038] In one embodiment, as Figure 6 shown, the knocking structure includes a knocking cavity 30 and a knocking plate 31. The knocking cavity 30 is opened on the front and rear sides of the feeding rack 24. The knocking plate 31 is fixedly installed on the front and rear sides of the feeding rack 24. A knocking block 36 is slidably installed inside the knocking cavity 30. One end of the knocking block 36 far away from the feeding rack 24 is fixedly connected to a third knocking part 35. A reciprocating component is installed at the left end of the knocking plate 31. The reciprocating component is connected to the third knocking part 35.
[0039] The reciprocating component drives the third knocking part 35 to move left and right, so that the knocking block 36 slides inside the knocking cavity 30. The knocking block 36 knocks on the outer side wall of the material bin 26, so that the compacted powder inside the material bin 26 vibrates continuously, avoiding the blockage of the blanking hole by the compacted powder, which affects the blanking of the material bin 26 into the material cavity.
[0040] In one embodiment, as Figure 2 and Figure 6 shown, the reciprocating component includes a knocking motor 32. The knocking motor 32 is installed at the left end of the knocking plate 31. The output end of the knocking motor 32 extends to the right end of the knocking plate 31 and is fixedly connected to a first knocking part 33. The other end of the first knocking part 33 is fixedly connected to a first rotating rod. The outer side wall of the first rotating rod is rotatably connected to a second knocking part 34. The other end of the second knocking part 34 is fixedly connected to a second rotating rod. The outer side wall of the second rotating rod is rotatably connected to the third knocking part 35.
[0041] The knocking motor 32 drives the first knocking part 33 to rotate. Then, one end of the second knocking part 34 connected to the first rotating rod makes a circular motion around the center of the knocking motor 32, so that the second knocking part 34 pushes the third knocking part 35 to move left and right, and further makes the knocking block 36 continuously knock on the outer wall of the material bin 26, avoiding the blockage of the blanking hole by the compacted powder.
[0042] In one embodiment, as Figure 1 and Figure 2 shown, a sealing plate is fixedly installed at the top of the left end of the material bin 26. The sealing plate is slidably attached to the bottom of the feeding rack 24.
[0043] When the material bin 26 moves to the material cavity for feeding, the sealing plate can block the material hole provided on the feeding rack 24 and communicated with the feeding pipe, avoiding the direct dropping of the compacted powder onto the support platform plate 15.
[0044] The above embodiments disclose a high-frequency welding magnetic rod pressing die. Among them, the staff transports the pressing powder to the inside of the blanking structure through the feeding pipe. The second electric push rod 25 is used to push the material bin 26 to move to the upper end of the material cavity. The sealing component stops the blanking hole for sealing. The pressing powder inside the material bin 26 flows into the material cavity. During the feeding process of the material bin 26 to the material cavity, the knocking motor 32 drives the first knocking piece 33 to rotate. As a result, one end of the second knocking piece 34 connected to the first rotating rod makes a circular motion with the center of the knocking motor 32 as the center of the circle. Thus, the second knocking piece 34 pushes the third knocking piece 35 to move left and right. Further, the knocking block 36 continuously knocks on the outer wall of the material bin 26, so that the pressing powder inside the material bin 26 vibrates continuously, avoiding the blockage of the blanking hole by the pressing powder. The pressing powder enters the material cavity. The fourth electric push rod 37 is used to push the upper pressing piece 38 to move downward. The upper pressing piece 38 enters the material cavity. The upper pressing piece 38 and the lower pressing piece 22 cooperate with each other, so that the pressing powder forms a blank. Subsequently, the first electric push rod 18 is used to push the lower pressing piece 22 to move upward, so as to eject the blank out of the material cavity. By repeating the above actions, the push block 27 can push the pressed blank to the outside of the support platform plate 15, facilitating the operation of the staff and improving the production efficiency.
[0045] The above is only the specific implementation manner of the present application, but the protection scope of the present application is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present application can easily think of changes or substitutions, which should all be covered within the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.
