Description

Technical Field

[0001] This utility model relates to the field of screening device technology, specifically a metal powder particle size sorting device for powder metallurgy. Background Technology

[0002] In the field of powder metallurgy, precise sorting of metal powder particles is crucial, as it directly affects product quality and performance. Most existing metal powder particle size sorting devices employ conventional technologies such as sieving and airflow separation. However, in actual production processes, these traditional devices reveal a significant problem: thick material buildup.

[0003] When a large amount of metal powder continuously enters the sorting device, due to the limitations of the device design in material guidance and dispersion, the powder tends to accumulate in key areas such as the screen and sorting chamber. Over time, the accumulated material layer gradually thickens, making it difficult for subsequent powder to pass smoothly through the sorting area. For example, in a screening device, a thick accumulation of material can cause the screen to be overloaded, some screen holes to become blocked, and the metal powder cannot pass through the screen normally according to the particle size requirements, greatly reducing screening efficiency and accuracy.

[0004] To address this issue, we propose a metal powder particle size sorting device for powder metallurgy. Utility Model Content

[0005] The purpose of this invention is to provide a metal powder particle size sorting device for powder metallurgy, which solves the problems mentioned in the background art.

A base plate is fixedly installed at the bottom of the two vertical plates. The two vertical plates and the base plate can provide stable support for the hopper.

[0012] Preferably, the flipping assembly includes:

[0013] The motor is located above the hopper;

[0020] This invention provides a metal powder particle size sorting device for powder metallurgy. This metal powder particle size sorting device for powder metallurgy has the following advantages:

This not only effectively prevents the accumulation of metal powder and ensures the smooth progress of the sorting process, but also the first spring gives the lever a micro-vibration effect, which can prevent metal powder from adhering to the surface of the lever and maintain the continuous and efficient operation of the device.

[0022] (2) The metal powder particle size sorting device for powder metallurgy uses a cylindrical rod and an arc groove working together with a second spring to make the screen cylinder vibrate up and down during the sorting process. This design can effectively avoid screen cylinder blockage and allow metal powders of different particle sizes to pass through the screen cylinder more efficiently for sorting, which greatly improves the quality and effect of sorting work.

[0028] To provide a clearer understanding of the technical features, objectives, and effects of this utility model, the specific embodiments of this utility model are now described with reference to the accompanying drawings.

[0029] A preferred embodiment of the powder metallurgy particle size sorting device provided by this utility model is, for example... Figures 1 to 4 As shown: A metal powder particle size sorting device for powder metallurgy, comprising:

[0030] Hopper 1, arranged vertically;

[0031] A screen cylinder 7 is installed inside the hopper 1. The upper end of the screen cylinder 7 is slidably connected to the inner annular groove 92 opened on the inner wall of the hopper 1. Two vertical plates 2 are fixedly installed on the outer wall of the hopper 1. The two vertical plates 2 are symmetrically distributed on the left and right sides with the center line of the front of the hopper 1 as the axis of symmetry. A bottom plate 3 is fixedly installed at the bottom end of the two vertical plates 2. The two vertical plates 2 and the bottom plate 3 can provide stable support for the hopper 1.

[0032] Example 1: Reference Figure Figure 2 and Figure 3 The tilting component 8 is located between the hopper 1 and the screen cylinder 7.

[0033] Specifically, the flipping component 8 includes:

[0034] Motor 81 is located above hopper 1;

[0035] Mounting shaft 82 is fixedly mounted at its top end to the output end of motor 81, and a columnar rod 83 is fixedly mounted on the outer wall of mounting shaft 82;

[0036] The top end of the first spring 84 is fixedly installed on the lower surface of the cylindrical rod 83, and the bottom end of the first spring 84 is fixedly installed with a lever 85.

[0037] Here, the motor 81 is started, which drives the mounting shaft 82 and the cylindrical rod 83 to rotate. The cylindrical rod 83 drives the first spring 84 and the lever 85 to rotate, which can prevent metal powder from accumulating and use the micro-vibration of the first spring 84 to prevent powder from adhering to the lever 85.

[0038] In this embodiment, it should be noted that a mounting plate 6 is fixedly installed on the top surface of the motor 81. The two ends of the mounting plate 6 are fixedly installed on the side of the vertical plate 2. The mounting plate 6 can prevent the motor 81 from being suspended in the air, and can securely install the motor 81 so that the motor 81 can work normally.

[0039] Example 2, Reference Figure 3 and Figure 4 Vibration component 9 is located between hopper 1 and screen cylinder 7.

[0040] Specifically, the vibration assembly 9 includes a second spring 93, which is disposed in the inner annular groove 92. The bottom end of the second spring 93 is fixedly installed on the bottom of the inner wall of the inner annular groove 92, and the top end of the second spring 93 is fixedly installed on the screen cylinder 7. The top surface of the screen cylinder 7 is provided with an arc-shaped groove 91 that slides with the cylindrical rod 83.

[0041] Here, the cylindrical rod 83 squeezes the arc-shaped groove 91 during rotation, and combined with the second spring 93, it causes the screen cylinder 7 to vibrate up and down, effectively preventing the screen cylinder from clogging and improving the metal powder sorting efficiency.

[0042] In this embodiment, it should be noted that the outer edge of the arc groove 91 is rounded, which allows the cylindrical rod 83 to smoothly rotate out of the arc groove 91.

[0043] Furthermore, an extension cover 5 is provided on the outside of the lower end of the screen cylinder 7. The inner wall of the extension cover 5 is fixedly installed with the outer wall of the hopper 1. A collection box 4 is placed on the top surface of the bottom plate 3 below the extension cover 5. The extension cover 5 can prevent the screened metal powder from splashing and allow it to enter the collection box 4 smoothly.

[0044] Working principle: The metal powder to be sorted is poured into the screen cylinder 7 in the hopper 1 for sorting. At this time, the motor 81 is started to rotate the mounting shaft 82. The rotation of the mounting shaft 82 causes the cylindrical rod 83 to rotate. The rotation of the cylindrical rod 83 causes the first spring 84 to drive the lever 85 to rotate, preventing the metal powder from accumulating together and affecting the sorting work. Under the action of the first spring 84, the lever 85 can be slightly vibrated to prevent the metal powder from adhering to the surface of the lever 85. With the cooperation of the cylindrical rod 83 and the arc groove 91, the screen cylinder 7 can be squeezed during the rotation of the cylindrical rod 83. Then, under the setting of the second spring 93, the screen cylinder 7 can be vibrated up and down to prevent the screen cylinder 7 from clogging and to achieve better sorting.

Any equivalent changes and modifications made by those skilled in the art without departing from the concept and principles of this utility model should fall within the protection scope of this utility model. Furthermore, it should be noted that the components of this utility model are not limited to the overall application described above. Each technical feature described in the specification of this utility model can be used individually or in combination as needed. Therefore, this utility model naturally covers other combinations and specific applications related to the points of this utility model.
