Referring to fig. 1 to 3, a hard alloy press forming device 10 includes a base 100, a lower die mechanism 200, an upper die mechanism 300, a stirring cylinder 400 and a feeding mechanism 500, where the base 100 includes a vertical plate 110, a first mounting plate 120 and a second mounting plate 130, one end of the vertical plate 110 is mounted on the first mounting plate 120, the other end of the vertical plate 110 is connected with the second mounting plate 130, and the first mounting plate 120 and the second mounting plate 130 are arranged opposite to each other up and down. The lower die mechanism 200 is mounted to the first mounting plate 120, and the lower die mechanism 200 has a processing cavity 201. The upper die mechanism 300 is mounted to the second mounting plate 130. The stirring cylinder 400 is installed on the vertical plate 110 and used for containing the powder material and uniformly stirring the powder material. One end of the feeding mechanism 500 is installed on the stirring cylinder 400, the other end of the feeding mechanism 500 is installed on the lower die mechanism 200, and the feeding mechanism 500 is used for conveying the powder material from the stirring cylinder 400 to the processing cavity 201.
The technical scheme includes that a stirring cylinder 400 is adopted to uniformly stir powder materials, and the powder materials which are uniformly stirred and have uniform density are added into a processing cavity 201 through a feeding mechanism 500, so that an upper die mechanism 300 and a lower die mechanism 200 are mutually matched to press the powder materials with the same density in the processing cavity 201, uniform-density pressing is achieved, the size of a pressed blank is stable, the quality of the pressed blank is improved, and the technical problem of low quality and yield of the pressed blank is solved.
In some embodiments, referring to fig. 4 to 6, the stirring barrel 400 includes a barrel 410, a stirring assembly 420, and a stirring driving member 430, the barrel 410 is fixedly installed on the vertical plate 110, a side of the barrel 410 close to the lower die mechanism 200 has a discharge port 411 (see fig. 1) for the feeding mechanism 500 to pass through, the stirring assembly 420 is rotatably installed in the barrel 410, and the stirring driving member 430 is connected to the stirring assembly 420 to drive the stirring assembly 420 to rotate around a horizontal axis.
In order to solve the problem of how to achieve uniform stirring, the stirring assembly 420 is driven to rotate by the stirring driving member 430 according to the technical scheme adopted by the embodiment, so that the powder material in the cylinder 410 is uniformly stirred. It should be noted that, the stirring component 420 rotates around a horizontal axis to perform horizontal stirring, and discharges from the discharge port 411 on the side of the cylinder 410, instead of discharging from the bottom of the cylinder 410, so as to ensure that the powder material with uniform density can be continuously output to reach the processing cavity 201, and the situation that the density of the powder material changes along with the change of the feeding time does not occur. For example, if the stirring cylinder 400 is used for stirring in a vertical stirring manner, instead of rotating around a horizontal axis, due to the influence of gravity, the dense powder is deposited at the bottom of the cylinder 410, the dense powder is deposited above the cylinder 410, the density of the powder in the cylinder 410 is not uniformly distributed along the height direction, and the density of the powder material naturally conveyed to the processing cavity 201 is not uniform, which affects the green compact quality. For another example, if the stirring cylinder 400 discharges from the bottom instead of the discharge hole 411 on the side of the cylinder 410, the density of the initial powder material is high, and as time goes on, the density of the subsequent powder material is gradually reduced, that is, the density of the powder material conveyed to the processing cavity 201 is gradually reduced, so that the density distribution of the powder material in the processing cavity 201 is uneven, and the blank quality is affected.
In order to solve how stable stirring, avoid leading to the inhomogeneous problem of powder material distribution in the processing cavity 201 because of the vibration, the technical scheme that this embodiment adopted is that barrel 410 fixed mounting is on riser 110, stirring subassembly 420 rotationally installs in barrel 410, but not whole barrel 410 is rotatory and realize stirring powder material, thereby avoid the rotatory base 100 vibration that arouses to be connected with it of barrel 410, and then drive the vibration of lower mould mechanism 200 of installing on base 100, it is inhomogeneous to lead to the powder material in the processing cavity 201 to receive the vibration influence and appear density distribution, influence the compact quality.
Of course, in a specific application, the stirring cylinder 400 may be first stirred, then the stirring cylinder 400 stops stirring, and the feeding mechanism 500 conveys the powder material. Alternatively, the stirring cylinder 400 may stir and the feeding mechanism 500 may synchronously convey the material.
In this embodiment, stirring feed cylinder 400 is stirring, and feed mechanism 500 synchronous transport material not only improves work efficiency, and while stirring synchronous transport material, stirring subassembly 420 can be raised the material and adorn feed mechanism 500 in, avoids still additionally needing the part to shovel the feed mechanism 500 with the material on.
Specifically, the stirring driving member 430 may be selected from a driving mechanism such as a motor, a rotary cylinder, and the like. For example, the output shaft of the motor is connected to the stirring assembly 420 through a coupling, so as to drive the stirring assembly 420 to rotate.
Specifically, one end of the stirring driving member 430 is fixedly installed on the vertical plate 110, and the other end of the stirring driving member 430 is hermetically inserted into the cylinder 410 and is connected to the stirring assembly 420 located in the cylinder 410.

Specifically, with continued reference to fig. 4 to 6, the plurality of stirring blades 422 are staggered along the circumferential direction of the horizontal rotation shaft 421, so that the stirring is more complete and uniform.
Specifically, with continued reference to fig. 4 to 6, the plurality of stirring blades 422 are staggered along the axial direction of the horizontal rotation shaft 421, so as to stir more completely and uniformly.
Specifically, with continued reference to fig. 4 to fig. 6, the stirring blade 422 is a curved blade, and the stirring area is wider and the stirring area is larger, so that the stirring is more complete and uniform.
In some embodiments, referring to fig. 4 and 6, the feeding mechanism 500 includes a first roller 510, a second roller 520, and a conveyor belt 530, the first roller 510 is rotatably installed at the lower mold mechanism 200, the second roller 520 is rotatably installed inside the cylinder 410, and the conveyor belt 530 is disposed around the first roller 510 and the second roller 520 and penetrates the discharge port 411.
