[0002] In the process of powder metallurgy, mixing is a very important step. Whether the powder is mixed evenly is the key factor in whether the final product with consistent and stable performance can be obtained. Even mixing of powder helps to keep the composition and performance of each part consistent during the subsequent forming and sintering process.

[0003] Existing mixing equipment for powder metallurgy is mostly composed of a mixing barrel and a stirring mechanism arranged in the mixing barrel. The mixing barrel is arranged vertically or horizontally, and the stirring mechanism is used to drive the material (metal powder) to rotate circumferentially in the mixing barrel. Although it can make the material mixed inside the mixing barrel, during the circumferential rotation of the material in the mixing barrel, when the material is thrown to the upper area of ​​the mixing barrel by the stirring mechanism, the approximate movement trajectory of the material is semi-circular, and other positions in the upper area of ​​the mixing barrel are not dispersed with material. Therefore, the dispersion degree of the material is small, the mixing uniformity is poor, and the mixing efficiency is low. Summary of the invention

[0013] In one embodiment, among the three consecutive adjacent support rods, the material-diverting plates provided on two of the support rods are close to the side where the material outlet is located, and the material-diverting plate provided on the other support rod is far away from the side where the material outlet is located.

[0014] In one embodiment, a connecting hole is formed on the main shaft, the connecting hole passes through the support rod and the axis of the connecting hole is perpendicular to the axis of the support rod;

[0015] A thread groove is provided in the middle area of ​​the support rod, and first nuts are threadedly connected to both ends of the thread groove, and the first nut abuts against the main shaft.

[0016] In one embodiment, the hard steel ring is connected to the support rod via a connecting assembly.

[0038] like Figure 1-Figure 8As shown, a powder metallurgy mixing device includes a mixing barrel 100, a feed port 120, a discharge port 130 and a mixing assembly 200. A mixing chamber 110 is provided inside the mixing barrel 100. The feed port 120 is provided on one side of the upper portion of the mixing barrel 100, and the feed port 120 can communicate with the mixing chamber 110. The discharge port 130 is provided on the lower portion of the mixing barrel 100 and on the side opposite to the feed port 120, and the discharge port 130 can communicate with the mixing chamber 110. The mixing assembly 200 includes a main shaft 210, a plurality of support rods 220 and a plurality of prying plates 230. The main shaft 210 can rotate around its axis, and the main shaft 210 is rotatably connected to the mixing barrel 100, and the main shaft 210 penetrates the mixing chamber 110 along the length direction of the mixing chamber 110. 10. The axis of the main shaft 210 coincides with the center line of the mixing chamber 110. A plurality of support rods 220 are arranged on the main shaft 210 at equal intervals along the axis of the main shaft 210. The axes of two adjacent support rods 220 are perpendicular to each other. A plurality of material-dispensing plates 230 are evenly arranged on each support rod 220. There are two groups of material-dispensing plates 230 arranged on each support rod 220, and each group has at least one material-dispensing plate. The two groups of material-dispensing plates 230 are symmetrically arranged with the center line of the length direction of the support rod 220 as the axis of symmetry. The material-dispensing plates 230 include a hard steel ring 231 and an elastic sheet 232. The outer side of the hard steel ring 231 is connected to the support rod 220, and the inner side of the hard steel ring 231 is circumferentially surrounded by the edge area of ​​the elastic sheet 232. In the non-working state, the center of the elastic sheet 232 is convex.

[0039] When in use, the staff adds the metal powder of the material to be mixed into the feed port 120, and then opens the feed port 120, so that the material enters the mixing chamber 110 from the feed port 120, and the total amount of the material cannot exceed half of the mixing chamber 110, and then the main shaft 210 is rotated around its axis. Under the driving action of the main shaft 210, the support rod 220 rotates with the main shaft 210, and the support rod 220 drives the material plate 230 to rotate. When the material plate 230 rotates to the lower part of the mixing chamber 110, the elastic sheet 232 in the material plate 230 contacts the powder material, and the elastic sheet 232 is deformed into the center by the resistance from the metal powder. The concave shape can increase the amount of material that the material plate 230 can hold, so that more material is thrown to the upper part of the mixing chamber 110. Then, as the main shaft 210 continues to rotate, the elastic sheet 232 holds a certain amount of material and rotates to the upper part of the mixing chamber 110. At this time, the pressure of the material on the elastic sheet 232 is reduced, and the elastic sheet 232 recovers its deformation under its own elastic action. Therefore, the material is dispersed to the upper part of the mixing chamber 110 by the elastic force of the elastic sheet 232, so that the material is dispersed to a greater extent in the upper part of the mixing chamber 110, so that different metal powders can be mixed with each other, thereby improving the uniformity of material mixing and increasing mixing efficiency. In addition, it can be understood that the instantaneous large kinetic energy of the elastic sheet 232 when it is reset is also conducive to breaking the metal powders that are bonded together, reducing the amount and size of the bonded metal powder blocks.

[0040] When the powders in the mixing chamber 110 are mixed evenly, the staff can open the discharge port 130 to discharge the mixed materials from the mixing chamber 110 .

[0041] In a further embodiment, Figure 6 As shown, each group has at least two material-diverting plates 230 , which are inclined along the axis of the support rod 220 and the axis of the main shaft 210 . The inclined directions of the two adjacent material-diverting plates 230 in each group are opposite.

[0042] Since the inclination directions of the two adjacent material-diverting plates 230 in each group are opposite, one of the two adjacent material-diverting plates 230 will divert the material to move along the axis of the support rod 220 toward the direction close to the main shaft 210, and the other material-diverting plate 230 will divert the material to move away from the main shaft 210. Therefore, the materials will collide with each other along the axis of the support rod 220, thereby increasing the degree of mixing of the materials along the axis of the support rod 220, preventing the materials from being stratified in the axis of the support rod 220 and unable to mix with each other, thereby improving the mixing uniformity of the materials.

[0043] In a further embodiment, Figure 3 and Figure 4As shown, among the three consecutive adjacent support rods 220 , the material-diverting plates 230 provided on two of the support rods 220 are close to the side where the discharge port 130 is located, and the material-diverting plate 230 provided on another support rod 220 is far away from the side where the discharge port 130 is located.

[0044] Since the material stripping plates 230 provided on two of the three consecutive adjacent support rods 220 are close to the discharge port 130, the material moves toward the location of the discharge port 130 under the action of the above two material stripping plates 230. Since the material stripping plate 230 provided on another of the three consecutive adjacent support rods 220 is far away from the discharge port 130, the material flows toward the location far away from the discharge port 130 under the action of the material stripping plate 230. Therefore, the material as a whole still moves toward the location of the discharge port 130. In the process of the material moving toward the location of the discharge port 130, the material will collide with each other, thereby promoting the mixing of the material, improving the mixing uniformity of the material, and prolonging the mixing time of the material inside the mixing chamber 110, thereby ensuring uniform mixing of the material.

[0045] In a further embodiment, Figure 4 , Figure 5 and Figure 6 As shown, a connecting hole 211 is provided on the main shaft 210, the connecting hole 211 passes through the support rod 220 and the axis of the connecting hole 211 is perpendicular to the axis of the support rod 220, a thread groove 221 is provided in the middle area of ​​the support rod 220, and the two ends of the thread groove 221 are threadedly connected with a first nut 222, and the first nut 222 is in contact with the main shaft 210.

[0046] During installation, the staff first passes the support rod 220 through the connecting hole 211 so that the lengths of the two ends of the support rod 220 are basically the same, and then rotates the first nut 222 so that the first nut 222 rotates along the thread groove 221 until the first nut 222 is against the main shaft 210. At this time, the support rod 220 is fixedly installed on the main shaft 210.

[0047] In a further embodiment, Figure 4 , Figure 6 and Figure 7As shown, the hard steel ring 231 and the support rod 220 are connected to the support rod 220 through a connecting assembly 300, and the connecting assembly 300 includes a clamp 310, a female connecting block 320 and a male connecting block 330. A plurality of connecting annular grooves 223 are provided on the support rod 220 at equal intervals along the axis of the support rod 220. The clamp 310 is arranged in the connecting annular groove 223, and the female connecting block 320 is arranged on the outer peripheral surface of the clamp 310. The male connecting block 330 is inserted into the female connecting block 320. The sides of the male connecting block 330 and the female connecting block 320 are correspondingly provided with mounting holes 340, and a screw 350 is inserted in the mounting hole 340. One end of the screw 350 passing through the mounting hole 340 is threadedly connected to a second nut 360.

[0048] During installation, the staff first opens the clamp 310, then clamps the clamp 310 in the connecting ring groove 223, and then fixes the clamp 310. Next, the male connecting block 330 is inserted into the female connecting block 320, so that the mounting hole 340 on the side of the male connecting block 330 and the mounting hole 340 on the side of the female connecting block 320 are concentric, and then the screw 350 is inserted into the mounting hole 340. Finally, the second nut 360 is screwed on the end of the screw 350 that passes through the mounting hole 340, and the second nut 360 is abutted against the outer side of the female connecting block 320.

[0049] In a further embodiment, Figure 2 As shown, a maintenance slot 140 is provided on the peripheral wall of the mixing barrel 100 , the maintenance slot 140 is connected to the mixing chamber 110 , a maintenance cover 150 is provided in the maintenance slot 140 , and the maintenance cover 150 blocks the maintenance slot 140 in a non-maintenance state.

[0050] In the non-maintenance state, the maintenance cover 150 blocks the maintenance slot 140. When the mixing component 200 inside the mixing chamber 110 needs maintenance or inspection, the staff can remove the maintenance cover 150 from the maintenance slot 140. At this time, the staff can reach into the maintenance slot 140, remove the mixing component 200 inside the mixing chamber 110, and take it out from the maintenance slot 140.

[0051] It should also be noted that in order to facilitate the removal of the maintenance cover 150 from the maintenance slot 140, specifically, threaded countersunk holes can be opened at the four corners of the maintenance slot 140, and through holes can be opened at the corresponding four corners of the maintenance cover 150. During installation, the four threaded countersunk holes are made concentric with the four through holes, and then the screws are passed through the through holes and screwed into the threaded countersunk holes.

[0052] In a further embodiment, Figure 1 As shown, a frame 400 is provided at the lower part of the mixing barrel 100 .

[0053] The frame 400 is provided to support the mixing barrel 100 .

[0054] In a further embodiment, Figure 1 As shown, a driving module 500 is provided on the frame 400, and the driving module 500 is connected to the main shaft 210 to drive the main shaft 210 to rotate. Specifically, the driving module 500 includes a driving motor and a transmission belt set, the driving motor is provided on the frame 400, the output end of the driving motor is connected to the input end of the transmission belt set, and the output end of the transmission belt set is connected to the main shaft 210.

[0055] When the main shaft 210 needs to be driven to rotate, the driving module 500 is started, that is, the driving motor is started, and the driving motor drives the transmission belt assembly to rotate, and the transmission belt assembly drives the main shaft 210 to rotate, so that the main shaft 210 rotates around its axis.

[0056] In a further embodiment, Figure 1 As shown, shock-absorbing pads 600 are provided at the four bottom corners of the frame 400 .

[0057] The shock-absorbing pad 600 is provided to reduce the vibration generated by the device during operation, improve the processing accuracy and extend the life of the device.

[0058] Working principle: When mixing, the staff adds the metal powder of the material to be mixed into the feed port 120, and then opens the feed port 120, so that the material enters the mixing chamber 110 from the feed port 120. The total amount of the material cannot exceed half of the mixing chamber 110, and then starts the driving module 500. At this time, the output end of the driving motor drives the transmission belt group to rotate, and the transmission belt group drives the main shaft 210 to rotate. Under the driving action of the main shaft 210, the support rod 220 rotates with the main shaft 210, and the support rod 220 drives the material plate 230 to rotate. When the material plate 230 rotates to the lower part of the mixing chamber 110, the elastic sheet 232 in the material plate 230 contacts the powder material, and the elastic sheet 232 is deformed into a center by the resistance from the metal powder. The outer shape of the inner core is concave. At this time, the material stripper plate 230 can hold a certain amount of material. Next, as the main shaft 210 continues to rotate, the elastic sheet 232 holds a certain amount of material and rotates to the upper part of the mixing chamber 110. At this time, the pressure of the material on the elastic sheet 232 is reduced, and the elastic sheet 232 recovers its deformation under its own elastic action. Therefore, the material is dispersed to the upper part of the mixing chamber 110 by the elastic force of the elastic sheet 232, so that the material is more dispersed in the upper part of the mixing chamber 110, so that different metal powders can be mixed with each other, thereby improving the uniformity of material mixing and increasing mixing efficiency. When the powders inside the mixing chamber 110 are evenly mixed, the staff can open the discharge port 130 to discharge the mixed material from the mixing chamber 110.

[0059] During installation, the support rod 220 is first installed on the main shaft 210. Specifically, the staff first passes the support rod 220 through the connecting hole 211 so that the lengths of the two ends of the support rod 220 are basically the same. Next, the first nut 222 is rotated so that the first nut 222 rotates along the thread groove 221 until the first nut 222 abuts against the main shaft 210. At this time, the support rod 220 is fixedly installed on the main shaft 210. Next, the staff first opens the clamp 310, then clamps the clamp 310 in the connecting ring groove 223, and then fixes the clamp 310. Next, insert the male connecting block 330 into the female connecting block 320 so that the mounting hole 340 on the side of the male connecting block 330 is concentric with the mounting hole 340 on the side of the female connecting block 320, and then insert the screw 350 into the mounting hole 340, and finally screw the second nut 360 on the end of the screw 350 that passes through the mounting hole 340, and make the second nut 360 abut against the outer side surface of the female connecting block 320, so that the hard steel ring 231 and the support rod 220 are connected together through the clamp 310, the female connecting block 320 and the male connecting block 330.

[0060] During disassembly and maintenance, the staff can remove the maintenance cover 150 from the maintenance slot 140. At this time, the staff can reach into the maintenance slot 140, remove the mixing component 200 inside the mixing chamber 110, and take it out from the maintenance slot 140. To facilitate the removal of the maintenance cover 150 from the maintenance slot 140, specifically, threaded countersunk holes can be opened at the four corners of the maintenance slot 140, and through holes are opened at the corresponding four corners of the maintenance cover 150. During installation, the four threaded countersunk holes are made concentric with the four through holes, and then the screws are passed through the through holes and screwed into the threaded countersunk holes.

[0061] The technical features of the above embodiments may be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0062] The above-described embodiments only express several implementation methods of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that, for a person of ordinary skill in the art, several modifications and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention.
