Description
Technical Field
[0001] This utility model relates to the field of magnet processing and production technology, specifically to an operating box for magnetic powder processing. Background Technology
[0002] In the field of magnetic particle processing, efficient and precise production processes are crucial for product quality and corporate profits. Currently, most magnetic particle processing equipment still relies on single-person operation, with the molding and packaging processes of magnetic powder being completed by a single person. In this process, the operator must sequentially perform a series of steps, including magnetic powder loading, molding, and packaging, resulting in lengthy waiting times between processes and extremely low overall work efficiency. Furthermore, magnetic powder, as a material sensitive to environmental factors, readily reacts chemically with oxygen and moisture in the air during processing, significantly affecting its performance and product quality. While existing equipment recognizes the importance of inert gas protection, there are serious deficiencies in the air intake and exhaust layout. Some equipment only has a single air intake at the top of the chamber, and its location is off-center from the working area, leading to uneven diffusion of inert gas within the chamber and insufficient protection for areas at the edges of the working area. Utility Model Content
[0003] To address the above technical problems, this utility model provides an operating box for magnetic powder processing. By enabling two operators to work together without interfering with each other, work efficiency is effectively improved. The layout of the top air inlet and the side exhaust port ensures that inert gas evenly covers the two working areas, maintaining a stable inert protective atmosphere inside the box and preventing the magnetic powder from oxidizing upon contact with air.
[0004] A magnetic powder processing control box includes a sealed box body, a molding mechanism and a magnetic powder feeding mechanism disposed within the box body. The box body has a smooth worktable with a molding work area and a packaging work area. The molding mechanism and the magnetic powder feeding mechanism are located in the molding work area. The front side panel of the box body on the worktable has glove holes corresponding to the molding and packaging work areas, and a working window above the glove holes. Operating gloves are sealed to the glove holes. A molding die slides on the worktable surface. Material boxes and packaging materials are stacked on the worktable surface in the packaging work area. The back of the box body has a loading and unloading port with a sealed door panel. The top of the box body has air inlets corresponding to the molding and packaging work areas, with air inlets connected to air pipes for injecting inert gas into the box body. The sides of the box body have exhaust holes close to the worktable surface, with exhaust pipes connected to the exhaust holes. Furthermore, the work window is equipped with a transparent panel, such as glass or acrylic sheet, that is seamlessly connected to the box body, ensuring the box's airtightness without obstructing the operator's view. Two operators can work together without interfering with each other, effectively improving work efficiency. Specifically, two molding dies can be installed to reduce intermediate waiting time and improve the continuity of the molding and packaging processes.
[0005] Furthermore, the workbench is equipped with a debris collection port, below which is connected a collection chamber. Inside the collection chamber is a debris collection drawer slidably connected to the chamber. Specifically, the collection chamber is a semi-enclosed environment with an opening on one side, and the debris collection drawer is located at the opening. The drawer has a baffle covering the opening, and a sealing strip on the baffle ensures that the drawer is fully pushed into the collection chamber to form a sealing mechanism. The debris collection port on the workbench recycles and reuses scattered magnetic powder, reducing magnetic powder waste and lowering production costs.
[0006] Furthermore, a forming window is provided on one side of the forming working area of the housing, and the edge of the worktable extends into the forming window. The forming mechanism includes a top cylinder and a side cylinder arranged perpendicularly to each other within the forming window. Each of the top and side cylinders has a pressure block on its extension rod. An "L"-shaped positioning baffle is provided on the worktable at the forming window. A controller for controlling the top and side cylinders is located on one side of the housing near the forming window. Specifically, after the forming operator loads the forming mold, they send the mold below the top cylinder and position it using the "L"-shaped positioning baffle. Then, they press the controller, and the top and side cylinders drive the pressure blocks on their extension rods to press the forming mold from the top and side respectively, thus forming the magnetic powder into material.
[0007] Furthermore, the magnetic powder feeding mechanism includes a vibratory feeder mounted on the worktable, an electronic weighing device located at the feeding port of the vibratory feeder, and a magnetic powder receiving box mounted on the electronic weighing device. The electronic weighing device allows the molding operator to accurately control the amount of magnetic powder used for each filling of the molding die, avoiding waste and saving material costs.
[0008] Furthermore, the electronic weighing device is equipped with a weighing tray for placing the magnetic powder receiving box. A receiving box sensor connected to the vibratory feeder is located on one side of the weighing tray. The vibratory feeder has a magnetic powder feeding trough, and a baffle cylinder is installed at the opening of the trough. A baffle plate is connected to the extension rod of the baffle cylinder. A feeding regulator connected to both the vibratory feeder and the electronic weighing device is also located in the molding work area. The molding operator places the magnetic powder receiving box onto the weighing tray of the electronic weighing device. After the receiving box sensor detects the box, it sends a start signal to the vibratory feeder, which then begins to vibrate for stable feeding. The electronic weighing device weighs the powder in real time and is linked to the baffle cylinder. Feeding automatically stops when the magnetic powder weight reaches the set value. The feeding regulator allows for flexible setting of the target amount, avoiding waste due to excessive feeding or product quality issues caused by insufficient feeding during manual feeding.
[0009] Furthermore, the forming mold includes two side baffles, two end baffles, and a shaping mold. The two side baffles and two end baffles form a rectangular fastener frame. The shaping mold consists of an upper mold and a lower mold located within the fastener frame. The two ends of the side baffles are equipped with fastener blocks to engage the end baffles. The forming mold employs a flexible combination design of side baffles, end baffles, and the shaping mold, facilitating quick disassembly and reassembly by the operator and improving work efficiency.
[0010] Furthermore, the material box consists of a box body and a lid. The box body has evenly distributed material slots, and the packaging materials include fiber bags and sealing bags. Specifically, the packaging operator takes the molded material out of the molding die and places it into the material slots of the box body. When a material box is full, the lid is closed, and fiber bags and sealing bags are wrapped around the outside of the material box to protect the material.
[0011] Furthermore, the front panel of the housing has an inclined plane, on which the working window is located. Specifically, the inclined angle of the inclined plane is 45°, so that the field of view of the working window can cover the entire working area.
[0012] Compared with the prior art, the beneficial effects achieved by this utility model are as follows: The dual-person collaborative operation design significantly improves work efficiency. This utility model divides the workbench into independent and symmetrical pressing and packaging work areas. Each work area is equipped with a dedicated glove hole and working window, which can accommodate two operators working at the same time. After the operator in the pressing work area completes the magnetic powder filling and pressing, the pressing mold can be quickly transferred to the packaging work area through the smooth workbench. After the operator in the packaging work area takes out the pressed material, the empty pressing mold is returned, forming a highly efficient collaborative cycle of "pressing-transfer-retrieval-return", avoiding the waiting time of single-person operation. The layout of the top air inlet and the side exhaust outlet ensures that inert gas evenly covers the two working areas, maintains a stable inert protective atmosphere inside the chamber, and prevents the magnetic powder from oxidizing upon contact with air.

[0022] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.
[0023] like Figure 1-7As shown, a magnetic powder processing operating box includes a sealed box body 1, a forming mechanism 2 and a magnetic powder feeding mechanism 3 disposed within the box body 1. A smooth worktable 4 is provided within the box body 1, with a forming working area and a packaging working area on the worktable 4. The forming mechanism 2 and the magnetic powder feeding mechanism 3 are located in the forming working area. The front side panel of the box body 1 on the worktable 4 has glove holes 5 corresponding to the forming working area and the packaging working area, respectively, and a working viewing window 6 located above the glove holes 5. An operating mechanism is provided at the glove holes 5 and sealed thereto. The gloves are provided with a forming mold 7 that slides on the workbench 4. The packaging work area is provided with a material box 8 and packaging materials 9 stacked on the workbench 4. The back of the box 1 is provided with a loading and unloading port and a sealing door 11 at the loading and unloading port. The top of the box 1 is provided with an air inlet corresponding to the forming work area and the packaging work area. The air inlet is provided with an air inlet pipe 12 for injecting inert gas into the box 1. The sides of the box 1 are provided with exhaust holes close to the workbench 4 and exhaust pipes 13 are connected to the exhaust holes. Furthermore, the top of the housing 1 is equipped with an exhaust port and an exhaust fan 14. An electrically controlled air intake grille 15 is located at the air inlet, and an electrically controlled exhaust grille 16 is located at the exhaust port. A one-way valve is installed on the exhaust pipe 13. Before operation, the air intake grille 15 is closed, and the exhaust grille 16 and exhaust fan 14 are opened to extract air from the housing 1, creating a negative pressure inside. The pressure difference between the inside and outside of the housing 1 causes the operating gloves to expand, making it easier for the operator to put them on. After the operator has put on the operating gloves, the exhaust grille 16 and exhaust fan 14 are closed, and the air intake grille 15 is opened. An inert gas, such as nitrogen, is introduced into the housing 1 through the air intake pipe 12, and the air inside the housing 1 is discharged through the exhaust pipe 13, filling the housing 1 with a nitrogen atmosphere to prevent the internal magnetic powder from oxidizing due to contact with oxygen in the air. Furthermore, the working window 6 is equipped with a transparent plate, such as glass or acrylic sheet, that is sealed to the housing 1, ensuring the airtightness of the housing 1 without obstructing the operator's view. The box 1 is divided into a molding work area and a packaging work area, and a smooth workbench 4 is used to allow the molding mold 7 to slide back and forth between the molding work area and the packaging work area. After completing the magnetic powder filling and molding in the molding work area, the operator in the molding work area (hereinafter referred to as the molding operator) passes the molding mold 7 to the operator in the packaging work area (hereinafter referred to as the packaging operator). The packaging operator opens the molding mold 7 and takes out the molded material and puts it into the material box 8. Then, the empty molding mold 7 is returned to the molding operator. The two operators cooperate with each other without interfering with each other, which effectively improves work efficiency. Specifically, two molding molds 7 can be set to reduce intermediate waiting time and improve the continuity of the molding and packaging process.
[0024] In this embodiment, the workbench 4 is provided with a debris collection port 41, and a collection chamber 42 is connected below the debris collection port 41. A debris collection drawer 43 is slidably connected to the collection chamber 42. Specifically, the collection chamber 42 is a semi-enclosed environment with an opening on one side, and the debris collection drawer 43 is located at the opening. The debris collection drawer 43 is provided with a baffle covering the opening, and a sealing strip on the baffle ensures that the debris collection drawer 43 is fully pushed into the collection chamber 42 to form a sealing mechanism. The debris collection port 41 on the workbench 4 recycles and reuses scattered magnetic powder, reducing magnetic powder waste and lowering production costs.
[0025] In this embodiment, a forming window 21 is provided on one side of the forming working area on the housing 1. The edge of the workbench 4 extends into the forming window 21. The forming mechanism 2 includes a top cylinder 22 and a side cylinder 23 arranged perpendicularly to each other within the forming window 21. Each of the top cylinder 22 and the side cylinder 23 has a pressure block on its telescopic rod. An "L"-shaped positioning baffle 24 is provided on the workbench 4 at the forming window 21. A controller 25 for controlling the top cylinder 22 and the side cylinder 23 is provided on one side of the forming window 21 on the housing 1. Specifically, after the forming operator fills the forming mold 7, the forming mold 7 is sent to the bottom of the top cylinder 22 and positioned by the "L"-shaped positioning baffle 24. Then, the controller 25 is pressed, and the top cylinder 22 and the side cylinder 23 drive the pressure blocks on their telescopic rods to press the forming mold 7 from the top and side respectively, so that the magnetic powder is formed into material.
[0026] In this embodiment, the magnetic powder feeding mechanism 3 includes a vibratory feeder 31 mounted on the workbench 4, an electronic weighing device 32 mounted at the feeding port of the vibratory feeder 31, and a magnetic powder receiving box 33 mounted on the electronic weighing device. The electronic weighing device allows the molding operator to accurately control the amount of magnetic powder used for each filling of the molding die 7, avoiding waste and saving material costs.
[0027] In this embodiment, the electronic weighing device 32 is provided with a weighing tray 321 for placing the magnetic powder receiving box 33. A receiving box sensor 322 connected to the vibrating feeder 31 is provided on one side of the weighing tray 321. The vibrating feeder 31 is provided with a magnetic powder feeding trough 311. A baffle cylinder 312 is provided at the opening of the magnetic powder feeding trough 311. A baffle plate 313 is connected to the telescopic rod of the baffle cylinder 312. A feeding regulator 34 connected to the vibrating feeder 31 and the electronic weighing device 32 is also provided in the forming working area. The molding operator places the magnetic powder receiving box 33 onto the weighing tray 321 of the electronic weighing device 32. Upon detecting the magnetic powder receiving box 33, the receiving box sensor 322 sends a start signal to the vibratory feeder 31. The vibratory feeder 31 then begins vibrating to achieve stable feeding. The electronic weighing device 32 weighs the powder in real time and is linked to the material-blocking cylinder 312. When the weight of the magnetic powder reaches the set value, feeding automatically stops. Combined with the feeding regulator 34, the target quantity can be flexibly set, avoiding waste due to excessive feeding or product quality issues caused by insufficient feeding during manual feeding. The receiving box sensor 322 uses a laser sensor to detect object obstruction.
[0028] In this embodiment, the forming mold 7 includes two side baffles 71, two end baffles 72, and a shaping mold 73. The two side baffles 71 and the two end baffles 72 form a rectangular fastener frame. The shaping mold 73 consists of an upper mold and a lower mold disposed within the fastener frame. The two ends of the side baffles 71 are provided with fastener blocks 711 that fasten the end baffles 72. The forming mold 7 adopts a flexible combination design of the side baffles 71, end baffles 72, and shaping mold 73, facilitating quick disassembly and reassembly by the operator and improving work efficiency.
[0029] In this embodiment, the material box 8 consists of a box body 81 and a cover plate 82. The box body 81 is provided with evenly distributed material slots 811. The packaging material 9 includes fiber bags and sealing bags. Specifically, the packaging operator takes the molded material out of the molding mold 7 and puts it into the material slots 811 of the box body 81. When the box body 81 of a material box 8 is full, the cover plate 82 is closed, and fiber bags and sealing bags are wrapped around the outside of the material box 8 to protect the material.
[0030] In this embodiment, the front panel of the housing 1 is provided with an inclined plane, and the working window 6 is disposed on the inclined plane. Specifically, the inclined angle of the inclined plane is 45°, so that the field of view of the working window 6 can cover the entire working area.
[0031] The working principle of this utility model is as follows: Preparation: Open the sealing door 11, put the sealed magnetic powder and the material box 8 and packaging material 9 into the box 1 through the loading and unloading port, then close the sealing door 11. Inert gas is introduced into the box 1 through the air inlet pipe 12 and the air in the box 1 is discharged through the exhaust pipe 13, so that the box 1 is filled with nitrogen atmosphere. Then the magnetic powder packaging can be unsealed and put into the magnetic powder feeding mechanism 3. The box 1 is divided into a molding work area and a packaging work area. A smooth workbench 4 is used to allow the molding mold 7 to slide back and forth between the molding work area and the packaging work area. After the molding operator completes the magnetic powder filling and molding in the molding work area, he / she passes the molding mold 7 to the packaging operator. The packaging operator opens the molding mold 7 and takes out the molded material and puts it into the material box 8. Then, he / she returns the empty molding mold 7 to the molding operator. The two operators cooperate with each other without interfering with each other.
[0032] The beneficial effects of this utility model are as follows: The dual-person collaborative operation design significantly improves work efficiency. This utility model divides the workbench 4 into independent and symmetrical pressing work areas and packaging work areas. Each work area is equipped with a dedicated glove hole 5 and a working window 6, which can accommodate two operators working at the same time. After the operator in the pressing work area completes the magnetic powder filling and pressing, the pressing mold 7 can be quickly transferred to the packaging work area through the smooth workbench 4. After the operator in the packaging work area takes out the pressed material, the empty pressing mold 7 is returned, forming a highly efficient collaborative cycle of "pressing-transfer-retrieving-returning", avoiding the waiting time of single-person operation. The layout of the top air inlet and the side exhaust outlet ensures that the inert gas evenly covers the two working areas, maintains a stable inert protective atmosphere inside the housing 1, and prevents the magnetic powder from oxidizing upon contact with air.
