It includes a mounting frame, on the upper surface of which a template is fixedly connected. In the middle position of the upper surface of the template, a model groove is provided. A powder box is slidably connected to the upper surface of the template, and a feeding pipe is fixedly connected to the upper surface of the powder box. An unloading component is arranged inside the feeding pipe, and the unloading component includes a cylindrical groove opened on the lower surface of the feeding pipe. By providing the unloading component, after the powder box drives the cylindrical groove to be directly above the model groove, six sector-shaped sliders are driven to move into the first mounting groove, so that the metal powder enters the model groove through the cylindrical groove.

Description

Technical Field

[0001] The present invention relates to the technical field of powder metallurgy, and more specifically, to a powder metallurgy device for oil-impregnated bearings. Background Art

[0002] An oil-impregnated bearing, that is, a porous bearing, mainly uses metal powder as the raw material. The oil-impregnated bearing is a sintered body made by powder metallurgy. It is inherently porous and has technical advantages such as the number, size, shape, and distribution of pores that can be freely adjusted during the manufacturing process. Powder metallurgy is a technology for manufacturing metal materials, composite materials, and their products. By using metal powder (or a mixture of metal powder and non-metal powder) as the raw material, the process of forming and sintering is realized. This method is similar to the production of ceramics, so it is also called the cermet method.

[0003] When processing an oil-impregnated bearing by powder metallurgy, first, the metal powder is loaded into a mold for pressure forming; then it is sintered and solidified at a temperature below the melting point to finally form a metal product. However, when pressing and forming the metal powder, it reciprocates on the template of the powder box, so as to continuously add powder into the model grooves opened on the template. However, because there is a moving gap between the powder box and the template, when the powder box moves, some powder will stay on the surface of the template, which will not only adhere to the formed bearing blank, reducing the product quality of the bearing blank produced by this powder metallurgy device, but also cause waste of metal powder.

[0040] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention; obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0041] Please refer to Figures 1 to 11, an oil-impregnated bearing powder metallurgy device, including a mounting frame 1, on the upper surface of the mounting frame 1 is fixedly connected with a template 2, in the middle position of the upper surface of the template 2 is provided with a model groove 3, on the upper surface of the template 2 is slidably connected with a powder box 4, on the upper surface of the powder box 4 is fixedly connected with a feeding pipe 16, inside the feeding pipe 16 is provided with a discharging component 5, the discharging component 5 includes a cylindrical groove 51 opened on the lower surface of the feeding pipe 16, and the cylindrical groove 51 extends into the powder box 4, inside the powder box 4 at the central position of the cylindrical groove 51 is fixedly connected with a first straight rod 52;

[0042] On the lower side of the inner circular surface of the cylindrical groove 51 is opened a first installation groove 53, inside the first installation groove 53 are slidably connected several evenly distributed sector-shaped sliders 54, on the upper surfaces of the sector-shaped sliders 54 are fixedly connected with first cylinders 57, on the upper ends of the inner walls of the first installation groove 53 are opened evenly distributed first sliding grooves 55, and the first cylinders 57 are respectively slidably connected inside the first sliding grooves 55, on the upper ends of the inner walls of the first sliding grooves 55 are jointly opened a second installation groove 56, inside the second installation groove 56 is rotatably connected with a first ring 58, on the upper surface of the first ring 58 are opened evenly distributed first arc-shaped through grooves 59, and the first cylinders 57 are respectively slidably connected inside the first arc-shaped through grooves 59.

[0043] As Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 As shown, there are six sector-shaped sliders 54, on one side of the upper end of the inner wall of the second installation groove 56 is opened a second arc-shaped through groove 510, on the upper end of the inner wall of the second arc-shaped through groove 510 is opened a second sliding groove 512, on one side of the upper surface of the first ring 58 is fixedly connected with a second straight rod 511, and the second straight rod 511 is slidably connected inside the second arc-shaped through groove 510, inside the second sliding groove 512 is slidably connected with a first driving block 513, and the upper end of the second straight rod 511 extends into the first driving block 513 and is slidably connected inside the first driving block 513, on one side of the inner wall of the second sliding groove 512 is opened a round hole 514, inside the round hole 514 is provided with a first spring 515.

[0044] As Figure 5 、 Figure 6As shown in the figure, on the side of the inner wall of the second chute 512 away from the first spring 515, a third chute 516 is opened, and the third chute 516 penetrates through the outer surface of the powder box 4. A straight plate 517 is slidably connected inside the third chute 516, and the straight plate 517 is fixedly connected to the first driving block 513. On both sides of one side of the upper surface of the template 2, limiting plates 518 are fixedly connected. A push plate 519 is slidably connected inside the powder box 4 at a position away from the cylindrical groove 51. On one side of the outer surface of the powder box 4, two first telescopic rods 520 are fixedly connected, and one ends of the two first telescopic rods 520 extend into the powder box 4 and are fixedly connected to the push plate 519.

[0045] As Figure 1 , Figure 2 As shown in the figure, at the upper end of one side of the outer surface of the mounting frame 1 directly above the model groove 3, a second telescopic rod 10 is fixedly connected. At the center position of the lower end of the second telescopic rod 10, a model block 11 is fixedly connected. On one side of the upper surface of the mounting frame 1 close to the template 2, a third telescopic rod 13 is fixedly connected. On one side of the outer surface of the third telescopic rod 13, two mounting plates 12 are fixedly connected. One ends of the two mounting plates 12 are fixedly connected to the powder box 4. At the middle position on the side of the outer surface of the powder box 4 away from the mounting plate 12, an arc-shaped groove 14 is opened. A rubber pad 15 is fixedly connected to the inner circular surface of the arc-shaped groove 14.

[0046] During use, metal powder is added into the powder box 4 through the feeding pipe 16. Then, the third telescopic rod 13 is started to push the powder box 4 to move in the direction of the model groove 3 on the template 2. When the powder box 4 moves above the model groove 3, the metal powder enters the model groove 3. Then, the third telescopic rod 13 is started to drive the powder box 4 to move away from the model groove 3. Then, the second telescopic rod 10 is started to drive the model block 11 to move downward, so that the model block 11 is inserted into the model groove 3, thereby pressing the metal powder inside the model groove 3 into a bearing blank. Then, the second telescopic rod 10 is started to pull out the model block 11. Finally, the bearing blank is pushed out of the model groove 3 through the template 2. Then, the third telescopic rod 13 is started to push the powder box 4 in the direction of the model groove 3 to add metal powder into the model groove 3. At the same time, the bearing blank processed last time is pushed away through the arc-shaped groove 14, and the rubber pad 15 can prevent damage to the bearing blank when the arc-shaped groove 14 pushes away the bearing blank.

[0047] However, since there is a moving gap between the powder box 4 and the template 2, when the powder box 4 moves, some powder will stay on the surface of the template 2, which will not only adhere to the formed bearing blank, reducing the product quality of the bearing blank produced by this powder metallurgy device, but also cause waste of metal powder. Therefore, a discharging component 5 is provided. When the powder box 4 moves above the model groove 3, the cylindrical groove 51 and the first straight rod 52 are located directly above the model groove 3. Then, the first spring 515 pushes the first driving block 513 to move away from the circular hole 514 in the second sliding groove 512, thereby driving the second straight rod 511 to move inside the second arc-shaped through groove 510, and at the same time driving the first ring 58 to rotate inside the second installation groove 56. Then, through the sliding of the first cylinder 57 in the first sliding groove 55 and the first arc-shaped through groove 59, six first cylinders 57 are driven to move away from the cylindrical groove 51 at the same time, thereby driving six sector-shaped sliders 54 to move away from the cylindrical groove 51 at the same time, so that the six first cylinders 57 move into the first installation groove 53 at the same time, opening the cylindrical groove 51, and enabling the metal powder inside the powder box 4 to enter the model groove 3 through the cylindrical groove 51. When the powder box 4 moves away from the model groove 3, the limiting plate 518 pushes the straight plate 517 to move into the second sliding groove 512 in the third sliding groove 516, and at the same time pushes the first driving block 513 towards the circular hole 514, thereby driving the second straight rod 511 to move reversely in the second arc-shaped through groove 510, and further driving the first ring 58 to rotate reversely in the second installation groove 56. Then, through the sliding of the first cylinder 57 in the first sliding groove 55 and the first arc-shaped through groove 59, six sector-shaped sliders 54 are driven to move towards the first straight rod 52, so that one end of each of the six sector-shaped sliders 54 fits against the outer cylindrical surface of the first straight rod 52, and at the same time the six sector-shaped sliders 54 fit against each other, thereby closing the cylindrical groove 51 and preventing the metal powder from leaking out of the cylindrical groove 51. When the cylindrical groove 51 moves above the model groove 3, the cylindrical groove 51 is opened, enabling the metal powder to enter the model groove 3. When the cylindrical groove 51 moves away from the model groove 3, the cylindrical groove 51 is closed, thus effectively preventing the metal powder from leaking onto the upper surface of the template 2, preventing the metal powder from adhering to the formed bearing blank, improving the product quality of the bearing blank produced by this powder metallurgy device, and at the same time reducing the waste of metal powder. And through the setting of two limiting plates 518, the movement of the powder box 4 can be limited, ensuring that the powder box 4 and the template 2 fit closely, further reducing the leakage of metal powder. Then, by starting the first telescopic rod 520, the push plate 519 is pushed to move towards the cylindrical groove 51 inside the powder box 4, thereby pushing the metal powder inside the powder box 4 into the cylindrical groove 51, facilitating the reuse of the discharging component 5.

[0048] Such as Figure 3 , Figure 4 , Figure 7As shown, a plugging component 6 is arranged on the inner circular surface of the first mounting groove 53. The plugging component 6 includes six uniformly distributed fourth sliding grooves 61 opened on the inner circular surface of the first mounting groove 53. Six push rods 62 are slidably connected inside the six fourth sliding grooves 61, and the six push rods 62 are respectively located among the six. On one side of the upper surfaces of the six push rods 62, second cylinders 64 are fixedly connected. At the upper ends of the inner walls of the six fourth sliding grooves 61, fifth sliding grooves 63 are opened, and the six second cylinders 64 are respectively slidably connected inside the six fifth sliding grooves 63. At the upper ends of the inner walls of the six fifth sliding grooves 63, a third mounting groove 65 is jointly opened. A second ring 66 is rotatably connected inside the third mounting groove 65. Six uniformly distributed third arc-shaped through grooves 67 are opened on the upper surface of the second ring 66, and the six second cylinders 64 are respectively slidably connected inside the six third arc-shaped through grooves 67.

[0049] As Figure 4 , Figure 7 shown, on one side of the upper end of the inner wall of the third mounting groove 65, a fourth arc-shaped through groove 68 is opened. At the upper end of the inner wall of the fourth arc-shaped through groove 68, a sixth sliding groove 69 is opened, and the sixth sliding groove 69 and the third sliding groove 516 are on the same side. On one side of the upper surface of the second ring 66, a third straight rod 612 is fixedly connected, and the third straight rod 612 is slidably connected inside the fourth arc-shaped through groove 68. A second driving block 610 is slidably connected inside the sixth sliding groove 69, and the upper end of the third straight rod 612 extends into the second driving block 610 and is slidably connected inside the second driving block 610. Two second springs 611 are arranged on one side of the outer surface of the second driving block 610.

[0050] In the above embodiments, the six sector sliders 54 are driven to move simultaneously by the discharging assembly 5, so as to control the opening and closing of the cylindrical groove 51, and further control the discharge of the metal powder inside the cylindrical groove 51. However, when the six sector sliders 54 move into the first mounting groove 53 and the cylindrical groove 51 is opened, there are gaps between the six sector sliders 54, so that the metal powder will enter the gaps between the six sector sliders 54 inside the first mounting groove 53, affecting the movement of the six sector sliders 54 in the first mounting groove 53 and reducing the use effect of the discharging assembly 5. Therefore, a blocking assembly 6 is provided. When the six sector sliders 54 reach the inside of the first mounting groove 53, the second driving block 610 is pushed to move inside the sixth sliding groove 69 by the second spring 611, so as to drive the third straight rod 612 to move inside the fourth arc-shaped through groove 68, and at the same time drive the second ring 66 to rotate inside the third mounting groove 65. Then, the second cylinder 64 slides inside the fifth sliding groove 63 and the third arc-shaped through groove 67, so as to drive the six second cylinders 64 to move towards the inside of the first mounting groove 53, and at the same time drive the six push rods 62 to move towards the inside of the first mounting groove 53 inside the fourth sliding groove 61, so that the six push rods 62 are respectively inserted between the six sector sliders 54, thereby blocking the gaps between the six sector sliders 54, preventing the metal powder from entering the inside of the first mounting groove 53, ensuring the movement of the six sector sliders 54 in the first mounting groove 53, and improving the use effect of the discharging assembly 5.

[0051] As Figure 7 , Figure 8 shown, a driving assembly 7 is arranged between the second driving block 610 and the straight plate 517. The driving assembly 7 includes a connecting groove 71 formed between the sixth sliding groove 69 and the third sliding groove 516. A rotating rod 72 is arranged inside the connecting groove 71. One side of the upper surface of the rotating rod 72 close to the straight plate 517 is fixedly connected with a rotating shaft 77, and the lower end of the rotating shaft 77 penetrates through the lower surface of the rotating rod 72. The rotating shaft 77 is rotationally connected with the connecting groove 71. The upper surface of the second driving block 610 is fixedly connected with a third ring 73. One side of the upper surface of the rotating rod 72 close to the third ring 73 is provided with a first through groove 74, and the third ring 73 is slidably connected with the inside of the first through groove 74. One side of the outer surface of the straight plate 517 is provided with a fixed seat 76. One side of the upper surface of the rotating rod 72 close to the fixed seat 76 is provided with a second through groove 75, and the fixed seat 76 is slidably connected with the inside of the second through groove 75.

[0052] As Figure 8 , Figure 9As shown, a sliding component 8 is provided between the straight plate 517 and the fixed seat 76. The sliding component 8 includes a seventh chute 81 opened on one side of the outer surface of the straight plate 517 close to the fixed seat 76.

A fourth straight rod 83 is fixedly connected inside the seventh chute 81, and the fourth straight rod 83 passes through the first slider 82 and is slidably connected to the first slider 82. A third spring 84 is arranged on one side of the outer circular surface of the fourth straight rod 83 where the first slider 82 is located.

[0053] In the above embodiment, by controlling the movement of the six push rods 62 through the blocking component 6, the six push rods 62 are respectively inserted between the six sector-shaped sliders 54, which can prevent metal powder from entering the inside of the first installation groove 53 and improve the use effect of the discharging component 5. However, when the six sector-shaped sliders 54 move towards the first straight rod 52, since the six push rods 62 are respectively located between the six sector-shaped sliders 54, it is difficult for the six sector-shaped sliders 54 to move towards the first straight rod 52, reducing the use effect of the discharging component 5. Therefore, a driving component 7 is provided. When the limiting plate 518 pushes the straight plate 517 to move, the fixed seat 76 will be driven to move at the same time. Then, through the sliding connection between the fixed seat 76 and the second through groove 75, the rotating rod 72 is driven to rotate around the rotating shaft 77 inside the connection groove 71. Then, through the sliding connection between the third ring 73 and the first through groove 74, the third ring 73 is driven to move, thereby driving the second driving block 610 to move reversely inside the sixth chute 69, and then driving the third straight rod 612 to move reversely inside the fourth arc-shaped through groove 68. At the same time, the second ring 66 is driven to move reversely inside the third installation groove 65. Then, through the sliding of the second cylinder 64 inside the fifth chute 63 and the third arc-shaped through groove 67, the second cylinder 64 and the push rod 62 are driven to move towards the inside of the fourth chute 61, so that the push rod 62 is withdrawn from between the sector-shaped sliders 54 and moves into the fourth chute 61, facilitating the movement of the sector-shaped sliders 54. Then, the straight plate 517 is continuously pushed, thereby driving the first driving block 513 to move, and then starting the discharging component 5 to drive the six sector-shaped sliders 54 to move towards the first straight rod 52 to close the cylindrical groove 51, improving the use effect of the discharging component 5.

[0054] In the above embodiments, when the driving component 7 moves the straight plate 517, the fixed seat 76 is driven to move at the same time, so as to drive the second driving block 610 to move, and then drive the six push rods 62 to move into the fourth sliding groove 61, which facilitates the movement of the sector slider 54 and improves the use effect of the discharging component 5. However, because the fixed seat 76 is located inside the connecting groove 71 and the movement of the second driving block 610 is inside the sixth sliding groove 69, after the straight plate 517 drives the second driving block 610 to move through the driving component 7, the straight plate 517 cannot continue to move, which affects the normal use of the discharging component 5. Therefore, a sliding component 8 is provided. When the straight plate 517 drives the second driving block 610 to move to the limit, the fixed seat 76 is fixedly connected to the first slider 82, and the first slider 82 is slidably connected to the seventh sliding groove 81, so that the fixed seat 76 slides on the surface of the straight plate 517, so that the straight plate 517 can continue to move, ensuring the normal use of the discharging component 5. And the third spring 84 can push the first slider 82 to move in the reverse direction, so as to ensure that the first slider 82 can be reset. At the same time, the fourth straight rod 83 passes through the first slider 82, improving the stability of the movement of the first slider 82.

[0055] As Figure 10 , Figure 11 shown, a fixing component 9 is arranged inside the first slider 82 and the seventh sliding groove 81. The fixing component 9 includes a fourth installation groove 91 opened at a position on one side of the inner wall of the seventh sliding groove 81 close to the first driving block 513. A second slider 92 is slidably connected inside the fourth installation groove 91. A clamping block 93 is fixedly connected to one side of the outer surface of the second slider 92 close to the first slider 82. A clamping groove 94 is opened at a position on the outer surface of the first slider 82 corresponding to the clamping block 93. A second magnet 96 is fixedly connected to one side of the outer surface of the second slider 92 away from the clamping block 93. A first magnet 95 is fixedly connected to one side of the inner wall of the fourth installation groove 91 away from the clamping block 93, and the sides of the second magnet 96 and the first magnet 95 close to each other are both magnetic N poles.

[0056] As Figure 11As shown, on one side of the inner wall of the fourth installation groove 91 close to the first driving block 513, an eighth sliding groove 98 is opened. One end of the eighth sliding groove 98 extends to the side of the inner wall of the fourth installation groove 91 away from the first driving block 513. On one side of the outer surface of the second sliding block 92 close to the eighth sliding groove 98, a third through groove 97 is opened. A trapezoidal block 99 is slidably connected inside the eighth sliding groove 98, and one end of the trapezoidal block 99 extends into the third through groove 97. On the side of the outer surface of the trapezoidal block 99 away from the third through groove 97, a fourth spring 910 is provided. On the side of the inner wall of the eighth sliding groove 98 away from the trapezoidal block 99, an L-shaped groove 911 is opened. One side of the L-shaped groove 911 extends into the first driving block 513, and the upper end of the L-shaped groove 911 penetrates through the straight plate 517 and the upper surface of the first driving block 513. An L-shaped rod 912 is slidably connected inside the L-shaped groove 911, and one end of the L-shaped rod 912 passes through the eighth sliding groove 98 and is fixedly connected to the trapezoidal block 99

[0057] In the above-mentioned embodiment, through the sliding assembly 8, after the straight plate 517 drives the second driving block 610 to move to the limit, the straight plate 517 can continue to move, ensuring the normal use of the discharging assembly 5. However, due to the sliding connection between the first sliding block 82 and the seventh sliding groove 81, when the straight plate 517 moves, it cannot drive the fixed seat 76 to move in time, reducing the use effect of the driving assembly 7. Therefore, a fixing assembly 9 is provided. Since the opposite sides of the first magnet 95 and the second magnet 96 are both magnetic N poles, the first magnet 95 and the second magnet 96 repel each other, thereby pushing the second sliding block 92 to move towards the clamping groove 94 in the fourth installation groove 91, and then driving the clamping block 93 to move towards the clamping groove 94, so that the clamping block 93 is inserted into the clamping groove 94, thereby fixing the first sliding block 82. Furthermore, when the straight plate 517 moves, it can drive the fixed seat 76 to move in time, thereby starting the driving assembly 7 in time and improving the use effect of the driving assembly 7. Then, the straight plate 517 drives the first sliding block 82 and the fixed seat 76 to move. When the second driving block 610 moves to the limit, the fourth spring 910 drives the trapezoidal block 99 to move in the eighth sliding groove 98, so that the trapezoidal block 99 is inserted into the third through groove 97, thereby driving the second sliding block 92 to move towards the inside of the fourth installation groove 91, and then pulling the clamping block 93 out of the clamping groove 94, releasing the fixation of the first sliding block 82, thereby starting the sliding assembly 8 to facilitate the movement of the straight plate 517. And when the straight plate 517 is pushed out of the third sliding groove 516, it will push the L-shaped rod 912 to move in the L-shaped groove 911, thereby driving the trapezoidal block 99 to move towards the inside of the eighth sliding groove 98, so that the clamping block 93 is inserted into the clamping groove 94

[0058] Usage method: Add metal powder into the powder box 4 through the feeding pipe 16, and then start the third telescopic rod 13 to push the powder box 4 to move. After the cylindrical groove 51 moves above the model groove 3, start the discharging assembly 5 to drive the six sector-shaped sliders 54 to move into the first installation groove 53, open the cylindrical groove 51, so that the metal powder enters the model groove 3 from the cylindrical groove 51. At the same time, start the blocking assembly 6 to insert the six push rods 62 between the six sector-shaped sliders 54 respectively, and then start the third telescopic rod 13 to drive the powder box 4 to move away from the model groove 3, thereby pushing the straight plate 517 to move into the third sliding groove 516. At the same time, start the fixing assembly 9 to snap the clamping block 93 into the clamping groove 94, so that the straight plate 517 drives the first slider 82 and the second through groove 75 to move, thereby starting the driving assembly 7 to drive the second driving block 610 to move, and then starting the blocking assembly 6 to drive the six push rods 62 to move in the fourth sliding groove 61. Then, through the sliding assembly 8, make the straight plate 517 continue to move into the third sliding groove 516, thereby pushing the first driving block 513 to move, and then starting the discharging assembly 5 to drive the six sector-shaped sliders 54 to move towards the first straight rod 52 to close the cylindrical groove 51. Then continue to start the third telescopic rod 13 to drive the powder box 4 away from the model groove 3, and then start the second telescopic rod 10 to drive the model block 11 to move downward, so that the model block 11 is inserted into the model groove 3, thereby pressing the metal powder inside the model groove 3 into a bearing blank.
