Description

Technical Field

[0001] This utility model relates to the field of powder metallurgy production technology, specifically to a green billet post-processing device for powder metallurgy production. Background Technology

[0002] Powder metallurgy green blanks are an important step in the powder metallurgy process. They are made by placing metal powder in a mold and applying high pressure to make the powder particles come into close contact and form a preform. After the green blanks are sintered, they need to be post-processed to further improve their product performance.

[0003] A search revealed an existing patent (publication number: CN219986232U) that discloses a post-processing device for metal powder metallurgy. The device includes a processing box, a motor fixedly mounted at the center of the back of the box, a rotating cylinder fixedly connected to the motor's output, multiple baffles welded to the inner wall of the rotating cylinder, and atomizing nozzle assemblies fixedly connected to the four corners of the inner wall of the processing box. This post-processing device for metal powder metallurgy uses a motor to drive the rotating cylinder to rotate. Metal parts slide inside the rotating cylinder. When a metal part comes into contact with the side wall of a baffle, it rises as the rotating cylinder rotates and, under the influence of gravity, flips and falls from the baffle towards the bottom of the rotating cylinder. As the rotating cylinder continuously rotates, the metal parts continuously flip, ensuring that all surfaces of the metal parts are evenly heated and immersed in steam. This prevents uneven oxide film thickness on the surface of the metal parts, thus avoiding reduced rust prevention, wear resistance, and high-pressure penetration resistance.

[0004] However, in the above scheme, the metal parts are flipped inside the flipping cylinder, which causes the metal parts to collide with each other, resulting in wear and damage to the surface of the metal parts. Especially for gear products, the severe wear and collision between the teeth will lead to a decrease in the meshing accuracy of the product, and in severe cases, it will cause the product to be scrapped.

[0005] In view of this, the present invention proposes a green billet post-processing device for powder metallurgy production. Utility Model Content

[0006] This utility model proposes a green billet post-processing equipment for powder metallurgy production, which solves the problem in related technologies that makes it inconvenient to avoid collisions between gear-type metal parts due to flipping.

The filter assembly 2 is used to filter impurities such as powder metallurgy product debris in the discharged steam, which facilitates subsequent steam waste heat recovery; the placement rack 12 is placed on the bottom wall of the box 5, and the four corners of the top of the placement rack 12 are fixedly connected with the lifting rings 13. The two sides of the top of the placement rack 12 are equally spaced with placement grooves 11, and the inner wall of the placement grooves 11 is fitted with connecting rods 10; the limiting assembly 8 is assembled on the surface of the connecting rod 10, and the limiting assembly 8 is used to limit and clamp the gears sleeved on the surface of the connecting rod 10.

[0029] The limiting component 8 includes: a limiting ring 801 slidably connected to the surface of the connecting rod 10, with clamping brackets 802 fixedly connected to both ends of one side of the limiting ring 801; and a locking bolt 803 threadedly connected to the limiting ring 801, which is used to lock and fix the limiting ring 801 after it slides.

[0030] In this embodiment, the sliding limiting ring 801 is positioned at both ends of the gear, and the locking bolt 803 is tightened to achieve the limiting and fixing of the limiting ring 801 after sliding. Then, the gear is limited and fixed by two sets of limiting components 8, so as to achieve uniform distribution of the gear on the surface of the connecting rod 10 and avoid the collision of the gear caused by the connecting rod 10 sliding accidentally. At the same time, the gear is suspended in the air, which facilitates uniform contact with steam.

[0031] In a further preferred embodiment of the present invention, a limiting block 804 is fixedly connected to the inner wall of the limiting ring 801, and a limiting groove 805 that slides with the limiting block 804 is provided on the surface of the connecting rod 10.

[0032] In this embodiment, by utilizing the sliding of the limiting block 804 on the surface of the limiting groove 805, the smoothness of the sliding of the limiting ring 801 on the surface of the connecting rod 10 is improved.

[0033] In a further preferred embodiment of the present utility model, the shape of the clamping frame 802 is comb-shaped, and an integrated welded structure is formed between one side of the clamping frame 802 and one side of the limiting ring 801.

[0034] In this embodiment, by utilizing the comb-shaped clamping frame 802, it is convenient to clamp and limit the gear, and the contact area with the gear can be reduced.

[0035] In a further preferred embodiment of the present utility model, clamping blocks 14 are fixedly connected to both sides of the inner bottom wall of the box body 5, and clamping grooves 15 that are slidably engaged with the clamping blocks 14 are provided at the lower ends of both sides of the placement rack 12.

[0036] In this embodiment, by utilizing the engagement of the clamping blocks 14 inside the clamping grooves 15, the stability of the placement rack 12 placed on the inner bottom wall of the box body 5 is improved.

[0037] Embodiment 2

[0038] On the basis of Embodiment 1, a preferred embodiment of the green body post-treatment equipment for powder metallurgy production provided by the present utility model is as Figures 1 to 6 shown: The filtering component 2 includes: an installation groove 201 opened at the top end of the filtering box 3; a sealing plate 204 fixedly connected to the top end of the filtering box 3 by bolts, and a filtering plate 203 fixedly connected to the bottom end of the sealing plate 204 and extending into the interior of the filtering box 3.

[0039] In this embodiment, by simply filtering the discharged steam, impurities such as debris in the powder metallurgy gear products that may be contained in the steam are filtered and screened out, thereby facilitating the subsequent waste heat recovery of this part of the steam.

[0040] In a further preferred embodiment of the present utility model, a high-temperature resistant sealing ring 202 is fixedly connected to the lower end of the surface of the sealing plate 204, and the shape of the high-temperature resistant sealing ring 202 is square-shaped.

[0041] In this embodiment, by utilizing the square-shaped high-temperature resistant sealing ring 202, the sealing performance of the lower end of the sealing plate 204 engaged with the interior of the installation groove 201 is improved.

[0042] In a further preferred embodiment of the present utility model, the shape of the sealing plate 204 is inverted convex, and the cross-sectional area of the top end of the sealing plate 204 is larger than the cross-sectional area of the opening of the installation groove 201.

[0043] In this embodiment, by utilizing the sealing plate 204 with a larger area, it is convenient to completely block and seal the installation groove 201.

[0044] The working principle of this utility model is as follows: First, connect the pressure relief pipe 4 to the external heat exchange equipment, then connect the steam inlet pipe 7 to the external steam generator, then slide one of the limiting rings 801 onto the surface of the connecting rod 10, and let the limiting block 804 slide into the limiting groove 805 until the limiting ring 801 slides to the appropriate position on the surface of the connecting rod 10. Then tighten the locking bolt 803 to achieve the limiting fixation of the limiting ring 801 after sliding. After that, slide the gear onto the surface of the connecting rod 10, and let one end of it be in close contact with the clamping bracket 802. Slide the other limiting ring 801 onto it, so that the clamping bracket 802 on it is in close contact with the other end of the gear. Then, the gear is limited and fixed by the two sets of limiting components 8, so that the gear is evenly distributed on the surface of the connecting rod 10, and the collision of the gear is avoided due to the accidental sliding of the connecting rod 10.

[0045] Then, the external lifting equipment is connected to the lifting ring 13, and the placement rack 12 is lifted and placed into the box 5 by the external lifting equipment, so that the locking block 14 engages with the slot 15 to improve the stability of the placement rack 12 placed on the bottom wall of the box 5. Then, the door 1 is closed, and the external steam is then transported into the box 5 through the steam inlet pipe 7. Because the gear on the connecting rod 10 is suspended, it is easy to have uniform contact with the steam.

[0046] Excess steam will enter the filter box 3. At this time, the discharged steam is simply filtered to remove impurities such as debris from powder metallurgy gear products, which may be present in the steam. This facilitates the subsequent recovery of the waste heat of this steam. At the same time, the filter plate 203 can be slid out through the sealing plate 204 to facilitate cleaning and prevent clogging of the filter plate 203.

[0047] Those skilled in the art should connect all electrical components and their compatible power supplies in this case via wires, and should select appropriate controllers according to actual conditions to meet control requirements. The specific connection and control sequence should refer to the working principle described above, and the electrical connection should be completed by referring to the working sequence of each electrical component. The detailed connection methods are well-known technologies in the field. The above mainly introduces the working principle and process, and will not describe the electrical control.

[0048] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
