DETAILED DESCRIPTION

[0029] The present invention will now be described in further detail with reference to the accompanying drawings.

[0030] See also Figure 1-5 As shown, in this embodiment, a powder metallurgy pressing device is provided, comprising: a workbench 1, two support frames 2 are respectively installed on the upper side of the workbench 1, a material barrel 3 is installed above one of the support frames 2, a crushing assembly 4 is installed on one side of the material barrel 3, a model box 5 is installed at one end of the upper side of the workbench 1, a pressing assembly 6 corresponding to the model box 5 is installed on the lower side of the other support frame 2, and a transmission assembly 7 is connected between the peripheral side of the model box 5 and the lower side of the material barrel 3;

[0031] A beating assembly 8 corresponding to the transmission assembly 7 is installed on the upper side of the workbench 1. The beating assembly 8 includes a driving assembly 9 installed at the other end of the upper side of the workbench 1, a plate body 10 installed in the middle of the other end of the workbench 1, and a clapping board 11 that rotates and cooperates with the middle of the plate body 10 and corresponds to the transmission assembly 7. The driving assembly 9 is transmission-connected to one end of the clapping board 11.

[0032] The application of one aspect of this embodiment is: when the powder needs to be pressed and formed, the crushing component 4 is first started, and then the powder is put into the barrel 3. At this time, the crushing component 4 cuts and crushes the powder to achieve the crushing of large metal particles in the powder. At the same time, the cut and crushed powder is introduced into the model box 5 through the transmission component 7, and the driving component 9 is started. The driving component 9 drives one end of the clapper 11 to rotate. At this time, the clapper 11 strikes the side of the transmission component 7 back and forth, and can knock down the powder stuck to the inner wall of the transmission component 7. The powder knocked down at this time falls into the model box 5. After the powder is introduced, the pressing component 6 is started. At this time, the pressing component 6 squeezes the powder in the model box 5 to achieve the pressing and forming of the powder.

[0033] Through the provided crushing component 4, large metal particles in the powder can be cut and crushed, thereby reducing the occurrence of unevenness on the surface of the workpiece after pressing and forming, effectively improving the accuracy of the workpiece, and through the provided transmission component 7, the cut and crushed powder can be transmitted to the model box 5, preparing for the next step of the pressing component 6 to press and form the cut and crushed powder. At the same time, the provided driving component 9 can drive the clapper 11 to rotate, so that the clapper 11 strikes the peripheral side of the transmission component 7 back and forth, effectively reducing the occurrence of agglomeration and blockage caused by the cut and crushed powder sticking to the inner wall of the transmission component 7, effectively improving the feeding speed, and reducing the waste of resources. In addition, the provided pressing component 6 can press and form the cut and crushed powder to achieve the powder forming effect.

[0034] like Figure 2As shown, the crushing assembly 4 of this embodiment includes a feed port 12 opened on one side of the barrel 3, a crushing box 13 installed on one side of the feed port 12, two cutting rollers 14 rotatably fitted inside the crushing box 13, and a notch 15 opened on the lower part of one side of the crushing box 13, the notch 15 corresponding to the feed port 12; Figure 5 As shown, one end of each of the two cutting rollers 14 of this embodiment is fixed with a gear 16, and the other side of the crushing box 13 is fixed with a motor 17, the output end of the motor 17 is fixed to the axis of one of the gears 16, and the two gears 16 are meshed; Figure 3 As shown, a first cylinder 18 is fixed to the middle of the upper side of the barrel 3 of this embodiment, and a slide 19 is fixed to the output end of the first cylinder 18. The slide 19 slides and fits on the inner side of the barrel 3. The loading port 12 is located below the highest point of the slide 19, and a discharge port 20 is opened in the middle of the lower side of the barrel 3, and a valve is provided at the discharge port 20.

[0035] When it is necessary to cut and crush the large metal particles in the powder, first start the motor 17. The output end of the motor 17 drives one of its gears 16 to rotate, so that the two gears 16 engage and rotate, thereby driving the two cutting rollers 14 to rotate inward synchronously, and then put the powder into the crushing box 13, so that the two cutting rollers 14 can quickly cut and crush the large metal particles in the powder. At this time, the cut and crushed powder is introduced into the barrel 3 through the feeding port 12. After the introduction is completed, the valve at the discharge port 20 is opened, and the first cylinder 18 is started at the same time. At this time, the output end of the first cylinder 18 drives the slide 19 to descend, and the slide 19 drives the powder in the barrel 3 to move downward and squeezes the powder to the discharge port 20. At the same time, the slide 19 slides to fit the inner wall of the barrel 3.

[0036] like Figure 4 As shown, the transmission assembly 7 of this embodiment includes a hose 21 installed on the lower side of the barrel 3 and corresponding to the discharge port 20, a pipe 22 installed at the lower end of the hose 21, and a push plate 23 slidingly fitted in the pipe 22. The hose 21 and the pipe 22 are arranged vertically; Figure 2 As shown, one end of the pipe 22 of this embodiment is fixed with a second cylinder 24, the output end of the second cylinder 24 is fixed to the middle of the push plate 23, and a groove is opened at the lower part of one side of the mold box 5, and the other end of the pipe 22 corresponds to the groove; Figure 4 As shown, the driving assembly 9 of this embodiment includes an electric guide rail 25 fixed to the other end of the upper side of the workbench 1, a gear plate 26 fixed to the output end of the electric guide rail 25, and a sector gear 27 installed at one end of the clapper 11. The gear plate 26 is engaged with the sector gear 27, and the clapper 11 corresponds to the hose 21; Figure 1 As shown, the pressing assembly 6 of this embodiment includes a third cylinder 28 fixed to the middle of another support frame 2 and a pressing plate 29 fixed to the output end of the third cylinder 28 , and the pressing plate 29 corresponds to the mold box 5 .

[0037] When the powder needs to be pressed and formed, the powder in the barrel 3 is introduced into the hose 21 through the discharge port 20. At the same time, the powder falls into the pipe 22 according to its own gravity, and the electric guide rail 25 is started. The output end of the electric guide rail 25 drives the tooth plate 26 to move horizontally, so that the tooth plate 26 engages and rotates with the sector gear 27, so that the sector gear 27 drives the clapper 11 to rotate synchronously. At this time, the clapper 11 strikes the peripheral side of the hose 21 back and forth, so that the powder stuck to the inner wall of the hose 21 can be knocked down. At the same time, during the striking process, the hose 21 elastically expands and contracts according to its own elasticity and recovers. To its original state, the powder knocked down at this time falls into the pipe 22, and then the second cylinder 24 is started, and the output end of the second cylinder 24 drives the push plate 23 to move on the inner wall of the pipe 22, so that the powder in the pipe 22 can be pushed into the model box 5. After the pushing is completed, the second cylinder 24 drives the push plate 23 to move to the groove and close it. At this time, the third cylinder 28 is started, and the output end of the third cylinder 28 drives the pressing plate 29 to move downward. When the lower end of the pressing plate 29 is in contact with the powder in the model box 5, the pressing plate 29 applies pressure to the powder and presses it into shape, thereby realizing the pressing and molding of the powder.
