Description

Technical Field

[0001] This utility model relates to the field of powder metallurgy pressing and forming technology, and more specifically, to a pressing and forming device for producing powder metallurgy preforms. Background Technology

[0002] Powder metallurgy pressing equipment is a device used to press metal powder into a predetermined shape and density. This device is very important in the powder metallurgy industry and is widely used in the production of various precision parts and components.

[0003] According to patent authorization announcement number CN116765390B, announced on 2023-11-14, a powder metallurgy part pressing and forming machine relates to the field of powder metallurgy technology. Addressing the problem that existing methods can only press from one side, the following solution is proposed: It includes a base and a lower mold located on the upper side of the base. Multiple columns are fixedly connected to the upper side of the base, and a top plate is fixedly connected to the upper ends of the columns. A stamping mechanism cooperating with the lower mold is provided on the lower side of the top plate. A feeding mechanism for moving powder to the inside of the lower mold is provided on the upper side of the base, and an upper pressing mechanism for pressing the powder inside the lower mold is provided on the lower side of the base. The upper pressing mechanism and the stamping mechanism cooperate to simultaneously press the powder from both the upper and lower sides. An ejector mechanism cooperating with the upper pressing mechanism is provided inside the lower mold. This invention allows the metallurgical part to be pressed from both the upper and lower sides simultaneously, increasing the pressing strength and integrating the entire pressing and unloading process, reducing pressing time and improving efficiency. Although the invention excels in improving pressing strength and production efficiency, it lacks a cleaning mechanism, which may lead to metal powder overflow or residue during the pressing process. This powder accumulates on the worktable for a long time, increasing the gap between the pressing mechanism and the stamping mechanism, resulting in reduced pressing quality, easy production of defective products, and thus increased production costs.

[0004] Therefore, it is necessary to design a pressing and forming device for producing powder metallurgy preforms. Utility Model Content

[0005] In order to overcome the shortcomings of the prior art, this utility model provides a pressing and forming apparatus for producing powder metallurgy preforms.

[0006] The technical solution of this utility model is: a pressing and forming device for producing powder metallurgy billets, including a forming device, a working plate, an electric push rod and an electromagnet plate. The working plate is connected to the forming device, the electric push rod is installed on the working plate, the telescopic end of the electric push rod is connected to the electromagnet plate, and the lower side of the electromagnet plate is in contact with the upper side of the working plate.

[0007] Furthermore, it also includes a guide frame. The guide frame is connected to the work plate, and a feed port is opened on the side of the guide frame closest to the work plate. The feed port can fit into the electromagnet plate.

[0008] Furthermore, it also includes a fixing plate and a collection frame. The lower part of the forming device is connected to the fixing plate, and the collection frame is placed on the fixing plate. The guide frame is slidably connected to the collection frame, and the collection frame has holes and slots.

[0009] Furthermore, it also includes a vacuum cleaner, which is mounted on top of the molding device.

[0010] Furthermore, it also includes a mounting block, a fixing rod, a sliding rod, and a return spring. A fixing rod is installed at the lower part of the molding device, and a mounting block is installed at the lower part of the molding device. The mounting block has a slot, which can coincide with the slot on the collection frame. A sliding rod is slidably connected to the fixing rod, and a return spring is connected between the sliding rod and the mounting block.

[0011] Furthermore, the two sides of the electromagnet plate are curved.

[0012] The beneficial effects of this utility model are:

[0013] This invention utilizes an electric push rod and an electromagnet plate. The electromagnet plate attracts metal powder from the surface of the work plate. When the electromagnet plate aligns with the feed inlet on the guide frame, it is closed. At this point, the metal powder attracted to the electromagnet plate falls into the collection frame, thus cleaning the metal powder from the work plate. This effectively improves the pressing efficiency, ensures the quality of the metallurgical billets pressed by this device, and increases production efficiency. Attached Figure Description

Detailed Implementation

[0021] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0022] Example: A pressing and forming apparatus for producing powder metallurgy preforms, such as... Figure 1 and Figure 3 As shown, the device includes a forming device 1, a working plate 101, an electric push rod 2, and an electromagnet plate 3. The working plate 101 is connected to the forming device 1. The electric push rod 2 is mounted on the working plate 101 by a fixing component. The telescopic end of the electric push rod 2 is connected to the electromagnet plate 3, which has curved sides. The lower side of the electromagnet plate 3 is in contact with the upper side of the working plate 101. Driving the electric push rod 2 and the electromagnet plate 3, the telescopic end of the electric push rod 2 will move the electromagnet plate 3 towards the guide frame 4. During this process, the electromagnet plate 3 will adsorb the metal powder on the surface of the working plate 101. The curved sides of the electromagnet plate 3 effectively expand the adsorption range of the electromagnet plate 3, allowing the electromagnet plate 3 to adsorb more metal powder.

[0023] like Figure 1 and Figure 4 As shown, the device also includes a guide frame 4, a fixing plate 5, a collection frame 6, and a vacuum cleaner 7. The guide frame 4 is connected to the working plate 101, and a feed inlet is provided on the side of the guide frame 4 closest to the working plate 101. The feed inlet can fit with the electromagnet plate 3. The lower part of the forming device 1 is connected to the fixing plate 5, and the collection frame 6 is placed on the fixing plate 5. The guide frame 4 and the collection frame 6 are slidably connected. The collection frame 6 has a slot. When the electromagnet plate 3 fits with the feed inlet on the guide frame 4, the electromagnet plate 3 is closed. At this time, the metal powder adsorbed on the electromagnet plate 3 will fall into the guide frame 4 and enter the collection frame 6 along the guide frame 4, thus facilitating the collection of metal powder. The top of the forming device 1 is equipped with a vacuum cleaner 7. Driving the vacuum cleaner 7 will adsorb the metal powder raised during the powder metallurgy pressing process, preventing workers from inhaling it and causing harm to their bodies.

[0024] like Figure 5 and Figure 6As shown, it also includes a mounting block 102, a fixing rod 8, a sliding rod 9, and a return spring 10. The fixing rod 8 is installed at the lower part of the molding device 1, and the mounting block 102 is connected to the lower part of the molding device 1. The mounting block 102 has a slot, which can coincide with the slot on the collection frame 6. The sliding rod 9 is slidably connected to the fixing rod 8. The return spring 10 is connected to the mounting block 102 through a spring seat. When the collection frame 6 is reset, the return spring 10 will take the sliding rod 9 and re-fit with the slot on the mounting block 102 and the collection frame 6, thereby fixing the collection frame 6 again.

[0025] During the powder metallurgy pressing process of the forming device 1, when the working plate 101 moves down, the pressed metallurgical blank is removed from the lower mold for easy handling by the operator. During this process, the guide frame 4 moves down with the working plate 101. At this time, the guide frame 4 slides in the collection frame 6, so that the guide frame 4 and the collection frame 6 do not obstruct the operation of the forming device 1. When some residual metal powder accumulates on the working plate 101, the electric push rod 2 and the electromagnet plate 3 are driven. The telescopic end of the electric push rod 2 will move the electromagnet plate 3 towards the guide frame 4. During this process, the electromagnet plate 3 will adsorb the metal powder on the surface of the working plate 101. The two sides of the electromagnet plate 3 are curved, which effectively expands the adsorption range of the electromagnet plate 3, allowing the electromagnet plate 3 to adsorb more metal powder and move towards the discharge port on the guide frame 4. When the electromagnet plate 3 is aligned with the feed port on the guide frame 4, the electromagnet plate 3 is closed. At this time, the metal powder adsorbed on the electromagnet plate 3 will fall into the guide frame 4 and enter the collection box along the guide frame 4. Inside frame 6, the metal powder is collected, thus cleaning the metal powder on the work plate 101, effectively improving the pressing efficiency, ensuring the quality of the metallurgical blanks pressed by this device, and improving production efficiency. After completion, the electric push rod 2 is driven to reset the electromagnet plate 3, and the vacuum cleaner 7 is driven. The vacuum cleaner 7 will absorb the metal powder raised during the powder metallurgy pressing process, preventing workers from inhaling it and causing harm to their bodies. When the collection frame 6 needs to be disassembled, the sliding rod 9 is pulled up, and the return spring 10 will be compressed. When the sliding rod 9 is disengaged from the mounting block 102 and the slot on the collection frame 6, the collection frame 6 is removed from the forming device 1, and the metal powder inside the collection frame 6 is cleaned and collected for reuse. This allows the device to collect metal powder, effectively reducing the waste of metal powder, which is environmentally friendly and saves production costs. When the collection frame 6 is reset, the return spring 10 will take the sliding rod 9 and re-fit with the slot on the mounting block 102 and the collection frame 6, thus fixing the collection frame 6 back in place.
