Description

Technical Field

[0001] The present invention relates to the technical field of powder forming, in particular to a powder filling and guiding plate and a rotary powder forming press. Background Art

[0002] A powder forming press is a device that compresses metal or ceramic powder into a fixed shape (such as a block). Existing powder forming presses are typically single-shot or rotary presses. However, rotary presses are commonly used in the soft magnetic industry. They produce thicker-walled products with lower density. However, existing rotary presses are prone to insufficient powder filling, resulting in unstable product height and density. Summary of the Invention

[0003] The present invention aims to solve at least one of the technical problems existing in the prior art. To this end, the present invention provides a powder filling guide plate and a rotary powder forming press suitable for thin-walled, high-density products, which can improve production efficiency and stabilize the powder weight of the product.

[0004] In a first aspect, a powder filling and material guiding plate according to an embodiment of the present invention includes:

[0005] A main body, one side panel of the main body is provided with a mold cavity, the mold cavity is provided with a first feed port and a first discharge port, and the first feed port and the first discharge port are respectively provided at two ends of the mold cavity;

[0006] The powder conveying pipe fixing plate is installed on the side of the main body away from the mold cavity. The powder conveying pipe fixing plate is provided with a fixing hole, which is used to fix the powder conveying pipe. The powder conveying pipe fixing plate cover is arranged above the first feed port, and the fixing hole is connected to the first feed port.

[0007] A powder filling guide plate according to an embodiment of the present invention has at least the following beneficial effects: the powder filling guide plate is arranged at the inlet of the powder pressing chamber of the press, wherein it should be noted that the powder filling guide plate is installed on the turntable of the press. In the present application, the main body of the powder filling guide plate is provided with a mold cavity, and the mold cavity is provided with a first feed port and a first discharge port. The powder to be pressed enters the mold cavity from the first feed port and then enters the powder pressing chamber of the press. When the turntable of the press rotates the powder pressing chamber, the powder in the powder pressing chamber overflows from the powder pressing chamber during the pressing process and flows out to the turntable through the first discharge port of the mold cavity, and rotates back to the first feed port with the turntable, and re-enters the mold cavity. In addition, a powder conveying pipe fixing plate is provided on the main body for fixing the powder conveying pipe. It should be noted that the powder conveying pipe fixing plate and the main body are detachably mounted. This application utilizes a powder-filling guide plate to evenly feed powder into the pressing chamber, ensuring a uniform powder weight within the chamber. Furthermore, the powder-filling guide plate prevents excessive powder overflow from the pressing chamber as the powder delivery tube feeds powder into the chamber, ensuring consistent powder compression at the inlet. The overall structure is simple and practical, helping to improve product quality and efficiency.

[0008] According to an embodiment of the present invention, a powder filling guide plate is further provided with a powder return channel on its main body. The powder return channel is arranged adjacent to the mold cavity, and a second feed port and a second discharge port are respectively provided at both ends of the powder return channel. The second feed port and the first feed port are arranged on the same side as the second discharge port. When the powder conveying pipe is supplying powder, some powder will overflow from the first feed port. The powder that fails to enter the mold cavity and overflows will pass through the powder return channel and, driven by the turntable of the press, circulate to the second feed port of the powder return channel and the first feed port of the mold cavity, thereby preventing the overflowed powder from accumulating outside the powder filling guide plate and causing material waste.

[0009] According to an embodiment of the present invention, a powder filling guide plate is provided with a trumpet-shaped powder gathering groove at the second feed port, and the powder gathering groove is provided with a powder gathering port and a powder outlet. The powder gathering port is the end with a large diameter, and the powder outlet is the end with a small diameter. The powder outlet is connected to the second powder feed port. The trumpet-shaped powder gathering groove can better gather the powder refluxed from the turntable circulating with the press at the first feed port and the second feed port.

[0010] According to a powder filling and material guiding plate of an embodiment of the present invention, the first powder inlet is communicated with the powder gathering groove.

[0011] According to a powder filling and material guiding plate of an embodiment of the present invention, a sealing strip is provided at the edge of the cavity opening of the mold cavity to prevent powder from overflowing from the gap and enhance the sealing performance of the mold cavity.

[0012] According to an embodiment of the present invention, a powder filling and guide plate is provided with a strip groove on the main body. The strip groove is provided on the same side as the mold cavity and is provided along the edge of the cavity opening of the mold cavity. The sealing strip is embedded in the strip groove, which can realize rapid positioning and disassembly.

[0013] According to a powder filling and material guiding plate of an embodiment of the present invention, a connecting plate is provided at the edge of the main body, and the connecting plate is used for fixing the main body and the press.

[0014] According to a powder filling and material guiding plate of an embodiment of the present invention, the connecting plate is provided with a strip-shaped adjusting groove, and the connecting plate is connected to the press through the adjusting groove.

[0015] According to a powder filling and guiding plate of an embodiment of the present invention, an abutting plate is provided on a side of the main body close to the powder return channel, and an arc-shaped edge is provided on a side of the abutting plate away from the powder return channel.

[0016] In a second aspect, a rotary powder forming press according to an embodiment of the present invention employs the above-mentioned powder filling and guiding plate.

[0017] According to an embodiment of the present invention, a rotary powder molding press has at least the following beneficial effects: a powder filling guide plate is arranged at the inlet of the powder pressing chamber of the press, wherein it should be noted that the powder filling guide plate is installed on the turntable of the press. In the present application, the main body of the powder filling guide plate is provided with a mold cavity, and the mold cavity is provided with a first feed port and a first discharge port. The powder to be pressed enters the mold cavity from the first feed port and then enters the powder pressing chamber of the press. When the turntable of the press rotates the powder pressing chamber, the powder in the powder pressing chamber overflows from the powder pressing chamber during the pressing process and flows out to the turntable through the first discharge port of the mold cavity, and rotates back to the first feed port with the turntable, and re-enters the mold cavity. In addition, a powder conveying pipe fixing plate is also provided on the main body for fixing the powder conveying pipe. It should be noted that the powder conveying pipe fixing plate and the main body are detachably mounted. This application utilizes a powder-filling guide plate to evenly feed powder into the pressing chamber, ensuring a uniform powder weight within the chamber. Furthermore, the powder-filling guide plate prevents excessive powder overflow from the pressing chamber as the powder delivery tube feeds powder into the chamber, ensuring consistent powder compression at the inlet. The overall structure is simple and practical, helping to improve product quality and efficiency.
