Description

Technical Field

[0001] This invention relates to the field of powder dry pressing, and more particularly to a powder dry pressing device for forming irregularly shaped products. Background Technology

[0002] Dry powder pressing is a common powder metallurgy process that uses a mold to apply pressure to metal or non-metal powder at room temperature to shape it into the desired form.

[0003] In the process of molding workpieces, powder is filled into the mold and then extruded by the upper and lower molds. However, for irregularly shaped workpieces with concave and convex shapes on the upper and lower surfaces, the powder is prone to problems such as loose accumulation and local cavities during filling, resulting in insufficient filling and seriously affecting the quality of workpiece molding. In addition, after the workpiece is compacted and molded, it is tightly embedded in the mold and cannot be breathable, so it is easy to adhere to the mold surface. If it is directly forced to demold, the workpiece may be damaged locally, resulting in damage to the finished product.

[0004] In summary, this application proposes a powder dry pressing device for molding irregularly shaped products, which improves the technical problems mentioned above. Summary of the Invention

[0009] Furthermore, the diameter of filter plate one is larger than that of flow channel three.

[0010] Furthermore, it also includes two electric push rods three fixed to the mounting plate; the telescopic parts of the two electric push rods three are jointly fixed to a shield, and the shield is slidably connected to the upper mold; the shield is fixed to an arc-shaped pipe connected to an external pump; the arc-shaped pipe is connected to several suction pipes, and the suction pipes penetrate the shield.

[0011] Furthermore, it also includes an annular guide rail fixed to the shield; an electric slider is slidably connected to the annular guide rail; a fixed rod is fixed to the electric slider; an electric push rod is fixed to the fixed rod; and a brush plate for cleaning the shaped workpiece is installed on the telescopic part of the electric push rod.

[0012] Furthermore, it also includes a DD motor; the DD motor is fixedly connected to the telescopic part of the electric actuator four; the output part of the DD motor is fixedly connected to a brush plate one that is rotatably connected to the telescopic part of the electric actuator four; two electric actuators five are fixedly connected to the front and rear sides of the brush plate one; and a brush plate two is fixedly connected to the telescopic parts of all the electric actuators five on the same side.

Detailed Implementation

[0031] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0032] Example 1: A powder dry pressing device for molding irregularly shaped products, referring to... Figures 1-11 As shown, the device includes a molding machine body 1, a forming mold 2, an electric push rod 3, a mounting plate 4, an upper mold 5, an electric push rod 6, and a lower mold 7. The molding machine body 1 is fixedly connected to the forming mold 2. Several electric push rods 3 are fixedly connected to the upper side of the molding machine body 1. All the telescopic parts of the electric push rods 3 are fixedly connected to a mounting plate 4. The upper mold 5 is fixedly connected to the mounting plate 4 and is located above the forming mold 2. An electric push rod 6 is fixedly connected to the lower side of the molding machine body 1. The telescopic part of the electric push rod 6 is fixedly connected to the lower mold 7 and is located below the forming mold 2.

[0033] It also includes a powder storage tank 8, a conveying pipe 9, a gas supply pipe 10, an exhaust pipe 11, and a vibration unit; the powder storage tank 8 is fixedly connected to the molding die 2; the powder storage tank 8 is connected to the conveying pipe 9, which is fixedly connected to the molding die 2, and an electrically controlled valve is installed on the conveying pipe 9; the conveying pipe 9 is connected to the gas supply pipe 10, which is connected to an external pump; the molding die 2 is fixedly connected to the exhaust pipe 11; the molding die 2 has a molding groove 21; a channel 22 is opened on the left side of the molding groove 21, and the conveying pipe 9 is connected to the channel 22; a flow channel 1 23 is opened on the right side of the molding groove 21; a flow channel 24 is opened on the left side of the molding groove 21, and the flow channel 24 is connected to the exhaust pipe 11; the lower die 7 has a flow channel 3 71; a vibration unit is connected to each of the flow channel 1 23, the flow channel 2 24, and the flow channel 3 71, and vibration is generated by the vibration unit so that the powder can be tightly filled in the molding groove 21.

[0034] The vibration unit includes a fixed rod 101, a rotating ring 102, a blade 103, and a striking ball 104; a fixed rod 101 is fixedly connected to each of the flow channels 1 23, 24, and 71; each fixed rod 101 is rotatably connected to three rotating rings 102; each rotating ring 102 is fixedly connected to several blades 103; each blade 103 is fixedly connected to a striking ball 104 by an elastic rope.

[0035] It also includes elastic telescopic rods 105, filter plate one 106 and filter plate two 107; two elastic telescopic rods 105 are fixedly connected to the channel 22; the telescopic parts of the two elastic telescopic rods 105 are jointly fixedly connected to a filter plate one 106; filter plate two 107 is fixedly connected to the upper side of the flow channel one 23.

[0036] The diameter of filter plate 106 is larger than that of flow channel 71. During demolding, this prevents powder from being filled into flow channel 71 and wasting powder.

[0037] The working steps of the above embodiment are as follows: In the process of dry pressing powder to form irregular workpieces, the operator first turns on the power of the equipment and fills the powder storage tank 8 with the required powder; then controls the electric push rod 6 to move the lower mold 7 upward into the forming groove 21 and seal the bottom of the forming groove 21; then opens the electric control valve on the conveying pipe 9 and fills the powder into the forming groove 21 through the channel 22 via the conveying pipe 9; after the quantitative filling is completed, controls the electric push rod 3 to move the mounting plate 4 and the upper mold 5 downward, so that the upper mold 5 enters the forming groove 21 and together with the lower mold 7 to compact the powder to form the formed workpiece 100; then controls the upper mold 5 and the lower mold 7 to move upward and remove the formed workpiece 100 from the forming groove 21, and finally removes the workpiece to complete the demolding.

[0038] For irregularly shaped workpieces with concave and convex shapes on both the top and bottom, insufficient filling of powder during filling can easily occur due to loose accumulation and local cavities, affecting the molding quality. Therefore, during the process of filling the molding groove 21 with powder through the conveying pipe 9 via the channel 22, an external pump is simultaneously started to introduce gas into the conveying pipe 9 through the gas supply pipe 10, using the airflow to drive the powder flow and prevent blockage. During filling, the upper mold 5 is controlled to move down into the molding groove 21 and stop above the channel 22, while the lower mold 7 moves up into the groove, so that the flow channel 3 71 is aligned and connected with the flow channel 1 23 and the flow channel 2 24 respectively, thereby forming a closed space and reducing powder escape. The gas flows through the flow channel 1 23, the flow channel 3 71, the flow channel 2 24 and the exhaust pipe 11 in sequence and is discharged. When the airflow passes through the flow channel 1 23, the flow channel 3 71 and the flow channel 2 24, it will push the blade 103, causing the rotating ring 102, the blade 103 and the striking ball 104 to rotate around the fixed rod 101, causing the striking ball 104 to swing and strike. The upper mold 2 or lower mold 7 is struck to generate vibration. This vibration causes the powder to be evenly filled into the cavity between the molding groove 21 and the lower mold 7. At the same time, during the filling process, the upper mold 5 is controlled to move down at regular intervals to initially compact the filled powder, and then moves up to reset and continue filling. This process is repeated until the filling is completed. After the filling is completed, the upper mold 5 is controlled to move down to complete the final compaction and molding. Through the continuous vibration of the striking ball 104 and the intermittent pre-pressing of the upper mold 5, problems such as powder accumulation and local cavities are effectively reduced, and the molding quality of the workpiece is improved. It should be noted that the top of the molded workpiece 100 after molding should be lower than the channel 22 to ensure that it is compacted in a closed space and to ensure the molding quality. During the pre-pressing process of the upper mold 5 moving down, the filter plate 106 at the channel 22 is blocked by the upper mold 5, and the powder filling is stopped. When the upper mold 5 moves up again above the channel 22, the restriction on the filter plate 106 is stopped, and the powder pushes the filter plate 106 open to continue the powder filling.

[0039] When demolding the workpiece after it has been formed, the workpiece is tightly fitted into the forming groove 21 and easily adheres to the surface of the forming mold 2. Direct demolding may cause local damage. Therefore, the following operations are performed during the demolding process: the upper mold 5 and the lower mold 7 are controlled to move upward. After the upper mold 5 passes through the channel 22, gas is introduced into the forming groove 21 again through the air supply pipe 10, allowing the gas to enter between the formed workpiece 100 and the wall of the forming groove 21, helping the workpiece to separate from the mold surface and facilitating demolding. At the same time, the gas flows through the first flow channel 23, the third flow channel 71, and the second flow channel 24 again, pushing the blade 103 and causing the striking ball 104 to vibrate continuously, further promoting the separation of the workpiece from the mold groove, reducing demolding damage, and improving the quality of the finished product. When the third flow channel 71 is aligned and connected with the channel 22 (e.g., Figure 7As shown), the upper mold 5 and lower mold 7 stop moving, and at this time the molded workpiece 100 has been moved out of the molding groove 21; when the workpiece is separated from the upper mold 5 and lower mold 7 in the future, gas continues to be introduced into the flow channel 3 71, and the vibration of the striking ball 104 assists in the separation of the workpiece from the upper mold 5 and lower mold 7, ensuring that the demolding process is smooth and complete.

[0040] Example 2: Based on Example 1, referring to... Figure 1 and Figures 7-11 As shown, it also includes an electric push rod 111, a shield 112, an arc-shaped tube 113, and a suction tube 114; the mounting plate 4 is fixedly connected to two electric push rods 111; the telescopic parts of the two electric push rods 111 are jointly fixedly connected to a shield 112, and the shield 112 is slidably connected to the upper mold 5; the shield 112 is fixedly connected to an arc-shaped tube 113, and the arc-shaped tube 113 is connected to an external pump; the arc-shaped tube 113 is connected to several suction tubes 114, and the suction tubes 114 penetrate the shield 112.

[0041] It also includes a ring guide rail 121, an electric slider 122, a second fixed rod 123, a fourth electric push rod 124, and a first brush plate 125; the shield 112 is fixedly connected to the ring guide rail 121; the ring guide rail 121 is slidably connected to the electric slider 122; the electric slider 122 is fixedly connected to the second fixed rod 123; the second fixed rod 123 is fixedly connected to the fourth electric push rod 124; the first brush plate 125 is installed on the telescopic part of the fourth electric push rod 124.

[0042] It also includes a DD motor 126, an electric actuator 127, and a brush plate 128; the telescopic part of the electric actuator 124 is fixedly connected to the DD motor 126; the output part of the DD motor 126 is fixedly connected to the brush plate 125, and the brush plate 125 is rotatably connected to the telescopic part of the electric actuator 124; two electric actuators 127 are fixedly connected to the front and rear sides of the brush plate 125; and all the telescopic parts of the electric actuators 127 on the same side are each fixedly connected to a brush plate 128.

[0043] It also includes a motor 201, a rotating frame 202, a transmission roller 203, a slide rail 205, and a placement box 206; a shield 112 has a through slot, and the rotating frame 202 is rotatably connected to the through slot; the shield 112 is fixedly connected to the motor 201, and the output part of the motor 201 is fixedly connected to the rotating frame 202; a number of transmission rollers 203 are rotatably connected to the rotating frame 202; the molding die 2 is fixedly connected to the slide rail 205; the molding machine body 1 is fixedly connected to the placement box 206, and the placement box 206 is located on the right side of the slide rail 205.

[0044] It also includes bristles 204; several bristles 204 are fixedly attached to the upper side of the rotating frame 202; the transfer roller 203 is configured as a brush roller. When the formed workpiece 100 is unloaded through the rotating frame 202, the bristles 204 and the transfer roller 203 configured as a brush roller can brush and clean its upper and lower surfaces to remove residual powder from its surface, so as to facilitate subsequent heat treatment.

[0045] The slide 205 is inclined downward from left to right to facilitate the molding workpiece 100 falling into the placement box 206.

[0046] Based on the above embodiment 1, in order to prevent the powder from escaping and causing loss under the action of airflow during the powder filling, pressing and molding and demolding process, the system simultaneously performs the following anti-escape and recovery operations: control the electric push rod 111 to drive the shield 112 to move down until it is in contact with the surface of the molding mold 2, and completely shield the pressing area; then start the external pump, and continuously suck the inside of the shield 112 through the arc tube 113 and the suction tube 114 to recover the powder that escaped during processing in time, so as to facilitate subsequent reuse and effectively reduce powder loss.

[0047] During powder dry pressing, due to pressure transmission attenuation, the bonding force between powder particles on the workpiece surface is weak. This makes it easy for particles to fall off during demolding and transfer, resulting in waste and potential harm to personnel health. Therefore, above where the molded workpiece 100 has moved out of the molding groove 21 (e.g., ... Figure 7 After (as shown), the following cleaning operations are performed: control the electric slider 122 to move along the annular guide rail 121, driving the fixed rod 123, the electric push rod 124 and the brush plate 125 to move around the formed workpiece 100; at the same time, control the electric push rod 124 to push the brush plate 125 to always be in contact with the surface of the formed workpiece 100, brushing off the loose powder particles attached to the side; during the cleaning process, cooperate with the suction pipe 114 to continuously suction, fully recover the brushed powder, prevent it from escaping into the environment, reduce material waste and ensure the safety of the staff.

[0048] After cleaning the sides of the molded workpiece 100, perform the demolding and transfer operation: first, control the upper mold 5 to move upward and separate from the workpiece, then start the motor 201 to drive the rotating frame 202 to rotate until it is aligned with the workpiece (e.g., Figure 11(As shown); then, control the DD motor 126 to turn the brush plate 125 from vertical to horizontal, and then drive the electric push rod 124 to extend, push out the molded workpiece 100 and separate it from the lower mold 7, so that it falls into the rotating frame 202 and slides into the placement box 206 along the slide 205, realizing the automatic demolding and collection of the workpiece; when the workpiece passes through the rotating frame 202, the upper and lower surfaces of the workpiece are brushed and cleaned by the brush bristles 204 and the transmission roller 203 of the brush roller structure, further removing residual powder and preventing particles from escaping and being wasted; after demolding, control the electric push rod 127 to drive the two brush plates 128 to move in opposite directions, respectively adhering to the surfaces of the upper mold 5 and the lower mold 7, cleaning the upper and lower molds at the same time as the brush plate 125 resets, avoiding powder residue from affecting subsequent processing.

The description of the above embodiments is only for the purpose of helping to understand the method and core ideas of the present application. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the ideas of the present application. Therefore, the content of this specification should not be construed as a limitation of the present application.
