Description

Technical Field

[0001] This utility model relates to the technical field of alloy powder screening equipment, specifically a manganese alloy powder screening device. Background Technology

[0002] Manganese alloy powder sieving is a key process in metallurgy, materials science, and powder metallurgy. It is mainly used to control powder particle size distribution, remove impurities, or classify powder to meet the requirements of subsequent molding, sintering, or 3D printing processes. For example, in the alloy grading and sieving device disclosed in Chinese patent literature (application number: CN202420619019.3), alloy powder is screened by placing the sieve plate assembly at an incline. However, alloy powder easily adheres to the sieve surface, causing mesh blockage, reducing the effective sieving area, and requiring frequent cleaning. Inclined sieves usually rely on gravity to drive powder flow, but powder tends to accumulate or slip at the sieve edge, resulting in some particles not fully contacting the sieve holes and affecting the grading accuracy.

[0003] Therefore, we propose a manganese alloy powder screening device. Utility Model Content

[0004] The purpose of this invention is to provide a manganese alloy powder screening device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a manganese alloy powder screening device, comprising a support, a column, and a screen; A connecting shaft is provided in the middle of the column, and the connecting shaft is connected to the column by a bearing; The support rod is mounted on the connecting shaft; A sliding groove is provided on the left half of the support rod; A threaded rod is disposed within the groove. A slider is mounted on the threaded rod. A first connecting rod is disposed on the top of the slider; The second connecting rod is connected to the top of the first connecting rod; The third connecting rod is connected to the top of the second connecting rod; A positioning ring is disposed on the upper part of the bracket; The fourth connecting rod is connected to the top of the third connecting rod, and the top of the fourth connecting rod is fixedly connected to the bottom of the screen. A placement plate is provided on the upper part of the column, and the placement plate is inclined. The mounting slot is located at the top of the column, and a first sphere is disposed within the mounting slot; A fixing rod is fixedly installed on the top of the first ball, and the top end of the fixing rod is fixedly connected to the bottom of the screen. A connecting column is provided on the upper right side of the support rod; A cam is disposed at the bottom of the connecting post; A geared motor is located at the rear end of the cam. A connecting groove is provided on the surface of the cam; The second sphere is disposed within the connecting groove; A fixing block is disposed on the top of the second sphere, and the top end of the fixing block is fixedly connected to the connecting column.

[0006] Preferably, the top of the chute is provided with a through groove, through which the first connecting rod passes and connects to the second connecting rod.

[0007] Preferably, the first connecting rod, the second connecting rod, the third connecting rod, and the fourth connecting rod are all connected to each other by pins.

[0008] Preferably, the left end of the threaded rod passes through the left end of the support rod, the threaded rod is movably connected to the left end of the support rod, and a nut is fixedly provided at the left end of the threaded rod.

[0009] Preferably, the slider has a threaded hole in the middle that mates with the threaded rod, the right end of the threaded rod is connected to the inner wall of the groove via a bearing, and the part of the threaded rod inside the groove is threaded.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: During the rotation of the threaded rod, the slider moves to the right or left. Since the support rod rotates up and down with the connecting shaft as the fulcrum, the up and down movement amplitude of the support rod near the connecting shaft decreases, while the up and down movement amplitude of the support rod far from the connecting shaft increases. Thus, the vibration amplitude of the screen is changed according to the left and right movement distance of the slider on the support rod. The screen vibration amplitude changes, and the screen amplitude is adjusted according to the different particle sizes of the powder. A larger amplitude is suitable for coarse particles, overcoming agglomeration or clogging, while a smaller amplitude is suitable for fine particles, avoiding excessive jumping that causes screen penetration. Dynamically adjusting the amplitude can optimize the screening efficiency at different stages. Moderate vibration breaks up powder agglomeration. In particular, for easily adsorbed nano-scale or high surface energy alloy powders, amplitude adjustment can balance the dispersing force and avoid excessive splashing. Through amplitude gradient design, the powder can be guided to flow in an orderly manner, reducing local accumulation. Attached Figure Description

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0014] Please see Figure 1-5This utility model provides a technical solution: a manganese alloy powder screening device, comprising a support 1, a column 2, a screen 13, a connecting shaft 3 disposed in the middle of the column 2, the connecting shaft 3 and the column 2 being connected by a bearing, a support rod 4 disposed on the connecting shaft 3, a sliding groove 5 disposed on the left half of the support rod 4, a threaded rod 6 disposed in the sliding groove 5, a slider 7 disposed on the threaded rod 6, a first connecting rod 8 disposed on the top of the slider 7, a second connecting rod 9 connected to the top of the first connecting rod 8, a third connecting rod 10 connected to the top of the second connecting rod 9, a positioning ring 11 disposed on the upper part of the support 1, a fourth connecting rod 12 connected to the top of the third connecting rod 10, the top end of the fourth connecting rod 12 being fixedly connected to the bottom of the screen 13, and a placement plate 14 disposed on the upper part of the column 2. 14 is inclined, and the mounting groove 15 is set on the top of the column 2. The first ball 16 is set in the mounting groove 15. The fixing rod 17 is fixedly installed on the top of the first ball 16. The top of the fixing rod 17 is fixedly connected to the bottom of the screen 13. The connecting column 18 is set on the upper right side of the support rod 4. The cam 19 is set at the bottom of the connecting column 18. The reduction motor 20 is set at the rear end of the cam 19. The connecting groove 21 is set on the surface of the cam 19. The second ball 23 is set in the connecting groove 21. The fixing block 24 is set on the top of the second ball 23. The top of the fixing block 24 is fixedly connected to the connecting column 18. The manganese alloy powder (hereinafter referred to as: powder) is screened. The powder is placed on the screen 13. The reduction motor 20 is started. The reduction motor 20 drives the cam 19 to rotate. The cam 19 rotates. During the process, the second ball 23 slides in the connecting groove 21, and at the same time, the second ball 23 moves up and down. The second ball 23 drives the connecting column 18 to move up and down through the fixing block 24, thereby the connecting column 18 drives the right end of the support rod 4 to move up and down. The support rod 4 swings up and down with the connecting shaft 3 as the fulcrum. The slider 7 is set on the support rod 4. The slider 7 drives the screen 13 to vibrate through the first connecting rod 8, the second connecting rod 9, the third connecting rod 10 and the fourth connecting rod 12 to screen the powder. When the screen screens the powder, the screen 13 vibrates by rolling in the mounting groove 15 through the first ball 16 set at the bottom of the fixing rod 17. The screened powder falls on the placement plate 14. The placement plate 14 is set at an inclination. The powder slides to the right end of the placement plate 14. A powder outlet is provided, and a collection device is installed at the bottom right end of the placement plate 14 to collect the screened powder. When the threaded rod 6 is rotated, the slider 7 has a threaded hole in the middle that mates with the threaded rod 6. During the rotation of the threaded rod 6, the slider 7 moves to the right or left. Since the support rod 4 rotates up and down around the connecting shaft 3, the vertical movement of the support rod 4 closer to the connecting shaft 3 is reduced, while the vertical movement of the support rod 4 farther away from the connecting shaft 3 is increased. Thus, the vibration amplitude of the screen 13 is changed according to the left and right movement distance of the slider 7 on the support rod 4. The vibration amplitude of the screen 13 is changed to adjust the screen amplitude according to the different particle sizes of the powder. A larger amplitude is suitable for coarse particles to overcome agglomeration or clogging, while a smaller amplitude is suitable for fine particles to avoid excessive jumping that could cause the screen to penetrate.Dynamically adjusting the amplitude can optimize the sieving efficiency at different stages. Appropriate vibration breaks up powder agglomerations, especially beneficial for easily adsorbed nanoscale or high surface energy alloy powders. Amplitude adjustment can balance dispersing forces and prevent excessive splashing. Through amplitude gradient design, the powder can be guided to flow in an orderly manner, reducing localized accumulation.

[0015] The top of the chute 5 is provided with a through groove 22. The first connecting rod 8 passes through the through groove 22 and is connected to the second connecting rod 9. The first connecting rod 8, the second connecting rod 9, the third connecting rod 10, and the fourth connecting rod 12 are all connected to each other by pins. During the vibration of the screen 13, the first connecting rod 8, the second connecting rod 9, the third connecting rod 10, and the fourth connecting rod 12 rotate by the pins.

[0016] The left end of the threaded rod 6 passes through the left end of the support rod 4, and the threaded rod 6 is movably connected to the left end of the support rod 4. A nut is fixedly installed at the left end of the threaded rod 6, and the nut is designed to allow the use of a tool (such as a wrench) to rotate the nut and drive the threaded rod 6 to rotate. The slider 7 has a threaded hole in the middle that mates with the threaded rod 6. The right end of the threaded rod 6 is connected to the inner wall of the slide groove 5 by a bearing. The part of the threaded rod 6 inside the slide groove 5 is threaded. During the rotation of the threaded rod 6, the slider 7 moves to the right or left by mates with the threaded hole.
