Description

Technical Field

[0001] The invention relates to the technical field of powder metallurgy, and more specifically to an oil-containing bearing powder metallurgy device. Background Art

[0002] Oil-containing bearings, also known as porous bearings, are made of metal powder as the main raw material. Oil-containing bearings are sintered bodies made by powder metallurgy. They are porous in nature and have the technical advantages of freely adjusting the number, size, shape and distribution of pores during the manufacturing process. Powder metallurgy is a technology for manufacturing metal materials, composite materials and their products. It is achieved by using metal powder (or a mixture of metal powder and non-metallic powder) as raw material through a forming and sintering process. This method is similar to the production of ceramics, so it is also called the metal ceramic method.

[0003] When processing oil-containing bearings through powder metallurgy, first, metal powder is loaded into a mold for pressure molding; then it is sintered and solidified at a temperature below the melting point to finally form a metal product. However, when the metal powder is pressed and molded, the powder box moves back and forth on the template, so that powder is continuously added to the model groove opened on the template. However, because there is a moving gap between the powder box and the template, part of the powder in the powder box will remain on the surface of the template when it moves, which will not only adhere to the molded bearing blank, reducing the product quality of the bearing blank produced by the powder metallurgy device, but also cause waste of metal powder.

[0022] like Figure 5 , Figure 6 As shown, a No. 3 slide groove 516 is opened on the side of the inner wall of the No. 2 slide groove 512 away from the No. 1 spring 515, and the No. 3 slide groove 516 penetrates the outer surface of the powder box 4, and a straight plate 517 is slidably connected inside the No. 3 slide groove 516, and the straight plate 517 is fixedly connected to the No. 1 driving block 513, and both sides of the upper surface of the template 2 are fixedly connected to the limiting plates 518, and a push plate 519 is slidably connected to the inside of the powder box 4 away from the cylindrical groove 51, and two No. 1 telescopic rods 520 are fixedly connected to one side of the outer surface of the powder box 4, and one end of the two No. 1 telescopic rods 520 extend to the inside of the powder box 4 and are fixedly connected to the push plate 519.

[0023] like Figure 1 , Figure 2As shown, the upper end of one side of the outer surface of the mounting frame 1 is located just above the model groove 3 and is fixedly connected to a No. 2 telescopic rod 10, the lower end center position of the No. 2 telescopic rod 10 is fixedly connected to a model block 11, the upper surface of the mounting frame 1 is fixedly connected to a No. 3 telescopic rod 13 on one side close to the template 2, one side of the outer surface of the No. 3 telescopic rod 13 is fixedly connected to two mounting plates 12, one end of the two mounting plates 12 is fixedly connected to the powder box 4, an arc groove 14 is provided at the middle position of the side of the outer surface of the powder box 4 away from the mounting plate 12, and the inner circular surface of the arc groove 14 is fixedly connected to a rubber pad 15.

[0024] During use, metal powder is added into the powder box 4 through the feeding tube 16, and then the No. 3 telescopic rod 13 is started to push the powder box 4 to move in the direction of the model slot 3 in the template 2. When the powder box 4 moves above the model slot 3, the metal powder enters the inside of the model slot 3, and then the No. 3 telescopic rod 13 is started to drive the powder box 4 to move in the direction away from the model slot 3, and then the No. 2 telescopic rod 10 is started to drive the model block 11 to move downward, so that the model block 11 is inserted into the inside of the model slot 3, thereby pressing the metal powder inside the model slot 3 into a bearing blank, and then the No. 2 telescopic rod 10 is started to extract the model block 11, and finally the bearing blank is pushed out of the model slot 3 through the template 2, and then the No. 3 telescopic rod 13 is started to push the powder box 4 to move in the direction of the model slot 3, add metal powder to the inside of the model slot 3, and at the same time, the bearing blank processed last time is pushed away through the arc groove 14, and the rubber pad 15 can prevent the arc groove 14 from causing damage to the bearing blank when pushing the bearing blank away.

[0025] However, because there is a gap between the powder box 4 and the template 2, part of the powder of the powder box 4 will remain on the surface of the template 2 when it moves, which will not only adhere to the formed bearing blank, reducing the product quality of the bearing blank produced by the powder metallurgy device, but also cause waste of metal powder. Therefore, a discharging assembly 5 is provided. When the powder box 4 moves to the top of the model slot 3, the cylindrical slot 51 and the No. 1 straight rod 52 are located directly above the model slot 3, and then the No. 1 spring 515 pushes the No. 1 driving block 513 to move in the No. 2 slide slot 512 away from the circular hole 514, thereby driving the No. 2 straight rod 511 to move inside the No. 2 arcuate slot 510, and at the same time driving the No. 1 ring 58 to rotate inside the No. 2 mounting slot 56, and then the No. 1 cylinder 57 slides inside the No. 1 slide slot 55 and the No. 1 arcuate slot 59. The six No. 1 cylinders 57 are driven to move in the direction away from the cylindrical groove 51 at the same time, thereby driving the six fan-shaped sliders 54 to move in the direction away from the cylindrical groove 51 at the same time, so that the six No. 1 cylinders 57 are moved into the No. 1 installation groove 53 at the same time, and the cylindrical groove 51 is opened, so that the metal powder in the powder box 4 enters the mold groove 3 through the cylindrical groove 51. When the powder box 4 moves in the direction away from the mold groove 3, the straight plate 517 is pushed in the No. 3 slide groove 516 to move into the No. 2 slide groove 512 through the limit plate 518. The first drive block 513 is pushed to move toward the circular hole 514, thereby driving the second straight rod 511 to move in the opposite direction in the second arc-shaped slot 510, and then driving the first ring 58 to rotate in the opposite direction in the second mounting slot 56, and then the first cylinder 57 slides inside the first slide slot 55 and the first arc-shaped slot 59, driving the six sector-shaped sliders 54 to move toward the first straight rod 52, so that one end of the six sector-shaped sliders 54 are all in contact with the outer circumferential surface of the first straight rod 52, and at the same time, the six sector-shaped sliders 54 are in contact with each other, so that The cylindrical groove 51 is closed to prevent the metal powder from leaking out from the inside of the cylindrical groove 51, so that when the powder box 4 moves from the cylindrical groove 51 to the top of the model groove 3, the cylindrical groove 51 is opened to allow the metal powder to enter the model groove 3. When the cylindrical groove 51 is away from the model groove 3, the cylindrical groove 51 is closed, thereby effectively preventing the metal powder from leaking to the upper surface of the template 2 and preventing the metal powder from adhering to the formed bearing blank, thereby improving the product quality of the bearing blank produced by the powder metallurgy device and reducing the waste of metal powder. The movement of the powder box 4 can be limited by setting two limit plates 518, which can ensure that the powder box 4 and the template 2 fit closely, further reducing the leakage of metal powder, and then by starting the first telescopic rod 520 to push the push plate 519 to move in the direction of the cylindrical groove 51 inside the powder box 4, the metal powder inside the powder box 4 is pushed into the cylindrical groove 51, which is convenient for the reuse of the discharge assembly 5.

[0026] like Figure 3 , Figure 4 , Figure 7As shown, a blocking assembly 6 is provided on the inner circular surface of the No. 1 mounting groove 53, and the blocking assembly 6 includes six evenly distributed No. 4 slide grooves 61 opened on the inner circular surface of the No. 1 mounting groove 53, and the six No. 4 slide grooves 61 are all slidably connected with push rods 62, and the six push rods 62 are respectively located between the six, and one side of the upper surface of the six push rods 62 is fixedly connected with a No. 2 cylinder 64, and the upper ends of the inner walls of the six No. 4 slide grooves 61 are all provided with a No. 5 slide groove 63, and the six No. 2 cylinders 64 are respectively slidably connected to the inside of the six No. 5 slide grooves 63, and the upper ends of the inner walls of the six No. 5 slide grooves 63 are commonly provided with a No. 3 mounting groove 65, and a No. 2 ring 66 is rotatably connected to the inside of the No. 3 mounting groove 65, and the upper surface of the No. 2 ring 66 is provided with six evenly distributed No. 3 arc-shaped through grooves 67, and the six No. 2 cylinders 64 are respectively slidably connected to the inside of the six No. 3 arc-shaped through grooves 67.

[0027] like Figure 4 , Figure 7 As shown, a No. 4 arc-shaped through groove 68 is provided on one side of the upper end of the inner wall of the No. 3 mounting groove 65, a No. 6 slide groove 69 is provided on the upper end of the inner wall of the No. 4 arc-shaped through groove 68, and the No. 6 slide groove 69 is located on the same side as the No. 3 slide groove 516, a No. 3 straight rod 612 is fixedly connected to one side of the upper surface of the No. 2 circular ring 66, and the No. 3 straight rod 612 is slidably connected to the inside of the No. 4 arc-shaped through groove 68, a No. 2 driving block 610 is slidably connected to the inside of the No. 6 slide groove 69, and the upper end of the No. 3 straight rod 612 extends to the inside of the No. 2 driving block 610 and is slidably connected to the inside of the No. 2 driving block 610, and two No. 2 springs 611 are provided on one side of the outer surface of the No. 2 driving block 610.

[0028] In the above embodiment, the six fan-shaped sliders 54 are driven to move simultaneously by the discharge component 5, thereby controlling the opening and closing of the cylindrical groove 51, and further controlling the discharge of the metal powder inside the cylindrical groove 51. However, when the six fan-shaped sliders 54 are moved into the No. 1 mounting groove 53 and the cylindrical groove 51 is opened, there are gaps between the six fan-shaped sliders 54, so that the metal powder will enter between the six fan-shaped sliders 54 inside the No. 1 mounting groove 53, affecting the movement of the six fan-shaped sliders 54 in the No. 1 mounting groove 53, thereby reducing the use effect of the discharge component 5. Therefore, a blocking component 6 is provided. When the six sector-shaped sliders 54 are inside the No. 1 mounting groove 53, the No. 2 spring 611 pushes the No. 2 driving block 610 to move inside the No. 6 sliding groove 69, thereby driving the No. 3 straight rod 612 to move inside the No. 4 arc-shaped through groove 68, and at the same time driving the No. 2 ring 66 to rotate inside the No. 3 mounting groove 65, and then the No. 2 cylinder 64 slides inside the No. 5 sliding groove 63 and the No. 3 arc-shaped through groove 67, thereby driving the six No. 2 cylinders 64 to move inside the No. 1 mounting groove 53, and at the same time driving the six push rods 62 to move inside the No. 1 mounting groove 53 in the No. 4 sliding groove 61, so that the six push rods 62 are respectively inserted between the six sector-shaped sliders 54, thereby blocking the gaps between the six sector-shaped sliders 54, preventing metal powder from entering the No. 1 mounting groove 53, ensuring the movement of the six sector-shaped sliders 54 in the No. 1 mounting groove 53, and improving the use effect of the discharging component 5.

[0030] like Figure 8 , Fig. 9As shown, a sliding assembly 8 is arranged between the straight plate 517 and the fixed seat 76, and the sliding assembly 8 includes a No. 7 slide groove 81 opened on the outer surface of the straight plate 517 near the fixed seat 76. A No. 1 slider 82 is slidably connected inside the No. 7 slide groove 81, and the No. 1 slider 82 is fixedly connected to the fixed seat 76. A No. 4 straight rod 83 is fixedly connected inside the No. 7 slide groove 81, and the No. 4 straight rod 83 penetrates the No. 1 slider 82 and is slidably connected to the No. 1 slider 82. A No. 3 spring 84 is arranged on the outer cylindrical surface of the No. 4 straight rod 83 on one side of the No. 1 slider 82.

[0031] In the above embodiment, the movement of the six push rods 62 is controlled by the blocking assembly 6, so that the six push rods 62 are respectively inserted between the six fan-shaped sliders 54, which can prevent metal powder from entering the No. 1 mounting groove 53, thereby improving the use effect of the discharge assembly 5. However, when the six fan-shaped sliders 54 move toward the No. 1 straight rod 52, because the six push rods 62 are respectively located between the six fan-shaped sliders 54, the six fan-shaped sliders 54 are difficult to move toward the No. 1 straight rod 52, thereby reducing the use effect of the discharge assembly 5. Therefore, a driving assembly 7 is provided. When the limit plate 518 pushes the straight plate 517 to move, the fixing seat 76 is driven to move at the same time. Then, through the sliding connection between the fixing seat 76 and the second through groove 75, the rotating rod 72 is driven to rotate around the rotating shaft 77 inside the connecting 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 in the opposite direction inside the sixth slide groove 69, and then driving the third straight rod 612 to move in the opposite direction inside the fourth arc-shaped through groove 68, and at the same time driving the second ring 66 to move in the third mounting groove 65 moves in the opposite direction, and then slides in the No. 5 slide groove 63 and the No. 3 arc-shaped through groove 67 through the No. 2 cylinder 64, thereby driving the No. 2 cylinder 64 and the push rod 62 to move into the No. 4 slide groove 61, so that the push rod 62 is pulled out from between the fan-shaped sliders 54 and moves into the No. 4 slide groove 61, thereby facilitating the movement of the fan-shaped slider 54, and then continues to push the straight plate 517, thereby driving the No. 1 driving block 513 to move, and then starting the discharging component 5 to drive the six fan-shaped sliders 54 to move toward the No. 1 straight rod 52, closing the cylindrical groove 51, thereby improving the use effect of the discharging component 5.

[0032] In the above embodiment, when the straight plate 517 moves, the driving component 7 drives the fixed seat 76 to move at the same time, thereby driving the No. 2 driving block 610 to move, and then driving the six push rods 62 to move to the inside of the No. 4 slide groove 61, which facilitates the movement of the fan-shaped slider 54 and improves the use effect of the discharge component 5. However, because the fixed seat 76 is located inside the connecting groove 71 and the movement of the No. 2 driving block 610 is inside the No. 6 sliding groove 69, after the straight plate 517 drives the No. 2 driving block 610 to move through the driving assembly 7, the straight plate 517 cannot continue to move, affecting the normal use of the discharging assembly 5. Therefore, a sliding assembly 8 is provided. When the straight plate 517 drives the No. 2 driving block 610 to move to the limit, it is fixedly connected to the No. 1 sliding block 82 through the fixed seat 76, and the No. 1 sliding block 82 is slidingly connected to the No. 7 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 assembly 5, and the No. 3 spring 84 can push the No. 1 sliding block 82 to move in the opposite direction, thereby ensuring that the No. 1 sliding block 82 can be reset, and at the same time, the No. 4 straight rod 83 penetrates the No. 1 sliding block 82, thereby improving the stability of the movement of the No. 1 sliding block 82.

[0033] like Fig.10 , Fig.11 As shown, a fixing component 9 is arranged inside the No. 1 slider 82 and the No. 7 slide groove 81, and the fixing component 9 includes a No. 4 mounting groove 91 provided at a position close to the No. 1 driving block 513 on one side of the inner wall of the No. 7 slide groove 81, and a No. 2 slider 92 is slidably connected inside the No. 4 mounting groove 91, and a clamping block 93 is fixedly connected to the side of the outer surface of the No. 2 slider 92 close to the No. 1 slider 82, and a clamping groove 94 is provided on the side of the outer surface of the No. 1 slider 82 close to the clamping block 93 and at a position corresponding to the clamping block 93, and a No. 2 magnet 96 is fixedly connected to the side of the outer surface of the No. 2 slider 92 away from the clamping block 93, and a No. 1 magnet 95 is fixedly connected to the side of the inner wall of the No. 4 mounting groove 91 away from the clamping block 93, and the side where the No. 2 magnet 96 and the No. 1 magnet 95 are close to each other are both magnetic N poles.

[0034] like Fig.11As shown, an eighth slide groove 98 is provided on the inner wall of the fourth installation groove 91 near the first drive block 513, and one end of the eighth slide groove 98 extends to the inner wall of the fourth installation groove 91 away from the first drive block 513.

The outer surface of the trapezoidal block 99 is A fourth spring 910 is provided on the side away from the third through slot 97, an L-shaped slot 911 is provided on the inner wall of the eighth slide slot 98 away from the trapezoidal block 99, one side of the L-shaped slot 911 extends into the interior of the first drive block 513, and the upper end of the L-shaped slot 911 passes through the straight plate 517 and the upper surface of the first drive block 513, an L-shaped rod 912 is slidably connected inside the L-shaped slot 911, and one end of the L-shaped rod 912 passes through the eighth slide slot 98 and is fixedly connected to the trapezoidal block 99 In the above embodiment, after the straight plate 517 drives the second driving block 610 to move to the limit through the sliding assembly 8, 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 slider 82 and the seventh slide groove 81, the straight plate 517 cannot drive the fixed seat 76 to move in time when moving, reducing the use effect of the driving assembly 7. Therefore, a fixing assembly 9 is set, and the first magnet 95 and the second magnet 96 are magnetic N poles on the opposite sides, so that the first magnet 95 and the second magnet 96 are separated from each other, thereby pushing the second slider 92 to move in the fourth installation groove 91 to the card groove 94, and then driving the card block 93 to move to the card groove 94, so that the card block 93 is inserted into the card groove 94, thereby fixing the first slider 82, and then 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, improving the use effect of the driving assembly 7. Then, the No. 1 slider 82 and the fixed seat 76 are driven to move through the straight plate 517. When the No. 2 driving block 610 moves to the limit, the No. 4 spring 910 drives the trapezoidal block 99 to move in the No. 8 slide groove 98, so that the trapezoidal block 99 is inserted into the No. 3 through groove 97, thereby driving the No. 2 slider 92 to move into the No. 4 installation groove 91, and then pulling the card block 93 out of the card groove 94, releasing the fixation of the No. 1 slider 82, thereby starting the sliding assembly 8, facilitating the movement of the straight plate 517, and when the straight plate 517 is pushed out from the No. 3 slide 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 into the No. 8 slide groove 98, so that the card block 93 is inserted into the card groove 94.
