Description

Technical Field

[0001] The present invention relates to the technical field of powder presses, and particularly to a magnetic field forming press. Background Art

[0002] A magnetic field forming press is a device used to press powder into workpieces and is widely used in industrial production. It mainly includes a powder weighing device, a powder feeding device, a forming device, and a glove box. The feeding device feeds the powder into the powder weighing device. After the powder weighing device weighs a fixed amount of powder, it is sent to the powder feeding device. The powder feeding device loads the powder and transports it to the forming device. The forming device presses and forms the powder into a workpiece through a mold.

[0003] In some existing powder presses, there is a situation where the mold of the forming device needs to be frequently replaced. In this type of powder press, when replacing the mold, it is necessary to disassemble the powder weighing device and the powder feeding device at the feeding end of the forming device, and at the same time disassemble the glove box at the discharging end of the forming device to provide a large operating space for replacing the mold. The operation is cumbersome and the mold replacement is inconvenient. Summary of the Invention

[0004] To solve the defect of inconvenient mold replacement in the material vehicle in the prior art, the present invention provides a magnetic field forming press.

[0005] The above technical object of the present invention is achieved through the following technical solutions:

[0006] The present invention provides a magnetic field forming press, which includes a frame, a powder weighing device, a powder feeding device, and a forming device. The forming device is arranged on the frame, and the forming device includes a mold for powder forming; the powder weighing device is used to weigh a fixed amount of powder, and the powder feeding device is used to transport the powder weighed by the powder weighing device to the forming device; the powder weighing device is arranged above the powder feeding device, and the powder feeding device can reciprocate above the forming device to sprinkle the powder into the mold.

[0007] The magnetic field forming press further includes a rear seal box and a glove box. The powder weighing device and the powder feeding device are arranged in the rear seal box; the rear seal box is rotatably connected to one side of the frame at the feeding end of the forming device, and the glove box is slidably arranged on one side of the frame at the discharging end of the forming device.

[0008] In this solution, the forming device is arranged on the frame. The frame is connected to the rear sealing box at the feeding end of the forming device. A powder weighing device and a powder feeding device are arranged in the rear sealing box. After the powder weighing device weighs a fixed amount of powder, it is loaded into the powder feeding device. The powder feeding device transports the powder above the mold of the forming device and reciprocates above the forming device to evenly sprinkle the powder into the mold, thus eliminating the need for manual leveling of the powder in the mold and facilitating the operation of the user. The frame is connected to the glove box at the discharging end of the forming device. The user can operate in the glove box to package the formed workpiece. Among them, the rear sealing box is rotatably connected to one side of the frame located at the feeding end of the forming device, and the glove box is slidably arranged on one side of the frame located at the discharging end of the forming device. Therefore, when the mold of the forming device needs to be replaced, only by rotating the rear sealing box and sliding the glove box can the rear sealing box and the glove box be separated from the frame to expose the forming device, thus facilitating the replacement of the mold of the forming device. After the mold is replaced, rotate the rear sealing box in the reverse direction and slide the glove box in the reverse direction so that the glove box and the rear sealing box are respectively installed on both sides of the frame, and its operation is simple and convenient.

[0009] Furthermore, a first locking mechanism for locking the rear sealing box to the frame is arranged on the rear sealing box, and a second locking mechanism for locking the glove box to the frame is arranged on the glove box.

[0010] In this solution, when the rear sealing box rotates to close one side of the frame located at the feeding end of the forming device, the rear sealing box is locked to the frame through the first locking mechanism; when the glove box moves to close one side of the frame located at the discharging end of the forming device, the second locking mechanism locks the glove box to the frame. Thus, when the mold does not need to be replaced, the rear sealing box and the glove box are stably connected to the frame so that the magnetic field forming press can work normally.

[0011] Furthermore, a rotating shaft is vertically arranged at the feeding end of the forming device on the frame, and a shaft sleeve rotatably matched with the rotating shaft is arranged at the edge of the rear sealing box.

[0012] In this solution, the frame and the rear sealing box are matched through the rotating shaft and the shaft sleeve, and the connection strength between the frame and the rear sealing box is good and the installation is convenient.

[0013] Furthermore, the magnetic field forming press further includes a walking track. The walking track is arranged on one side of the frame located at the discharging end of the forming device, and the walking track is arranged at the bottom of the glove box; walking wheels are connected to the bottom of the glove box, and the walking wheels are in rolling cooperation with the walking track.

[0014] In this solution, the glove box realizes the sliding setting of the glove box through the cooperation of the walking rollers and the walking track. Its structure is simple, the glove box slides smoothly, and the installation is convenient.

[0015] Furthermore, the powder feeding device includes a material truck, a driving electric cylinder, and a first support track. The driving electric cylinder is fixed inside the rear sealing box, and the driving end of the driving electric cylinder is connected to the material truck. The first support track is arranged inside the rear sealing box and extends in the direction close to the molding device. The material truck is slidably fitted on the first support track, and the material truck is used for loading powder materials and feeding the powder materials into the mold.

[0016] In this solution, the powder feeding device loads powder materials through the material truck, and the driving electric cylinder drives the material truck to move along the first support track to transport the powder materials to the mold. When feeding the powder materials into the mold, the driving electric cylinder also facilitates controlling the material truck to reciprocate above the mold to make the powder material feeding more uniform.

[0017] Furthermore, in some embodiments, a second support track is fixedly arranged above the mold on the frame, and the second support track is arranged corresponding to the first support track. When the rear sealing box rotates to close the frame, the second support track and the first support track are located on the same straight line.

[0018] In this solution, the first support track supports the material truck to move inside the rear sealing box. When the rear sealing box rotates to close the frame (i.e., the rear sealing box rotates to fit the frame), the first support track and the second support track correspond and are located on the same straight line. Thus, at this time, the material truck can switch from the first support track to the second support track to continue moving above the mold to transport the powder materials to the mold. Therefore, through the segmented arrangement of the first support track and the second support track, the normal rotation of the rear sealing box is not affected by the first support track and the second support track, and at the same time, when powder feeding is required, the first support track and the second support track can support the material truck to walk to the mold to add powder materials to the mold.

[0019] Furthermore, in some embodiments, at least one telescopic track is arranged outside the first support track. The telescopic track is connected to the rear sealing box, the telescopic track is arranged parallel to the first support track, and the first support track is slidably connected to the telescopic track.

[0020] In this solution, a telescopic track is also slidably arranged outside the first support track, and the first support track is connected to the rear sealing box through the telescopic track. When feeding powder, the driving electric cylinder drives the material truck to walk along the first support track in the direction close to the molding device, and the driving electric cylinder can also drive the first support track to slide relative to the telescopic track through the material truck to extend above the mold inside the frame to feed powder through the material truck. When the powder feeding is completed, the driving electric cylinder drives the material truck to walk along the first support track in the direction away from the molding device, and the driving electric cylinder also drives the first support track to slide relative to the telescopic track through the material truck to retract into the rear sealing box, so as to facilitate rotating the rear sealing box relative to the frame to open the frame.

[0021] Further, the material cart includes a vehicle body, a powder box, a bottom plate, and an opening and closing air cylinder. The vehicle body is movably engaged with the first support track. The powder box is used for loading powder materials, and the powder box is arranged inside the vehicle body and can move inside the vehicle body. The bottom plate is arranged at the bottom of the vehicle body. A material discharging opening is formed at the bottom of the powder box, and the material discharging opening is attached to the upper side of the bottom plate.

[0022] A powder discharging opening is formed on the bottom plate, and the powder discharging opening is arranged in a dislocation manner with respect to the material discharging opening. The cylinder body of the opening and closing air cylinder is fixed to the bottom plate, and the driving end of the opening and closing air cylinder is connected to the powder box. The opening and closing air cylinder can drive the powder box to move until the material discharging opening is aligned with the powder discharging opening.

[0023] In this solution, the material cart loads powder materials through the powder box inside the vehicle body, and the vehicle body is engaged with the first support track to drive the bottom plate, the powder box, and the opening and closing air cylinder to move. When transporting the powder materials, the bottom plate is attached to the material discharging opening at the bottom of the powder box to seal the powder box. When the material cart moves above the mold, the opening and closing air cylinder drives the powder box to move, so that the material discharging opening is aligned with the powder discharging opening, and the powder materials in the powder box are scattered into the mold. Thus, the powder materials in the powder box are not easily spilled onto the first support track during the transportation of the powder materials, reducing the loss of the powder materials during the powder feeding process, ensuring the powder feeding accuracy, and at the same time ensuring the sanitation of the working environment of the material cart, and it is not easy to affect the stable operation of the material cart due to the spilled powder materials between the first support track and the vehicle body. Compared with the solution in the traditional material cart where the powder box directly contacts the track to seal the material discharging opening of the powder box through the track, in this solution, the powder box does not contact the first support track, reducing the wear between the powder box and the first support track.

[0024] Further, the bottom plate is provided with a guiding slide rail, the guiding slide rail is arranged parallel to the opening and closing air cylinder, and the powder box is convexly provided with a guiding block in the direction towards the guiding slide rail, and the guiding block is slidably engaged with the guiding slide rail.

[0025] In this solution, the guiding slide rail is slidably engaged with the guiding block, making the movement of the powder box driven by the opening and closing air cylinder more stable.

[0026] Further, the material cart further includes a lifting air cylinder, the cylinder body of the lifting air cylinder is fixed to the vehicle body, and the driving end of the lifting air cylinder is connected to the bottom plate to drive the bottom plate, the opening and closing air cylinder, and the powder box to lift synchronously.

[0027] In this solution, the lifting cylinder is connected between the bottom plate and the vehicle body. When the material truck transports powder, the lifting cylinder drives the bottom plate, the powder box on the bottom plate, and the opening and closing cylinder to rise synchronously, so that the material truck is not likely to interfere with the components in the rear seal box. When the material truck moves above the mold, the lifting cylinder can drive the bottom plate, the powder box, and the opening and closing cylinder to descend, so that the bottom plate fits above the mold, so that the powder will not leak outside the mold during the process of sprinkling the powder into the mold, further ensuring the working environment hygiene of the magnetic field forming press. And during the process of repeatedly moving the material truck to sprinkle the powder into the mold, the bottom plate that fits above the mold can level the powder in the mold, reducing manual operation and improving processing efficiency.

[0028] Furthermore, a pneumatic gripper and a release agent spray head are connected to one end of the vehicle body close to the forming device. A tension spring is connected between the vehicle body and the bottom plate, and the tension spring is arranged on the side of the opening and closing cylinder facing the powder box.

[0029] In this solution, a pneumatic gripper and a release agent spray head are arranged at one end of the vehicle body close to the forming device. The release agent spray head sprays a release agent in the mold to facilitate demolding after the product is formed. The pneumatic gripper can grip the demolded product, so that the formed product can be taken and placed from the mold to the glove box through the material truck, without setting an additional mechanism for gripping the product, further streamlining the magnetic field forming press.

[0030] Furthermore, a limiting block is arranged on the outer side of the vehicle body. The first support track is arranged on the side of the vehicle body, and the first support track is provided with a sliding groove that can slidably cooperate with the limiting block.

[0031] In this solution, the first support track slidably cooperates with the limiting block on the outer side of the vehicle body. The vehicle body is supported laterally by the first support track, and the setting of the first support track will not affect the lifting of the bottom plate.

[0032] In summary, the present invention has the following beneficial effects:

[0033] In the present invention, the rear seal box is rotatably connected to one side of the frame at the feeding end of the forming device, and the glove box is slidably arranged on one side of the frame at the discharging end of the forming device. Thus, when it is necessary to replace the mold of the forming device, only need to rotate the rear seal box and slide the glove box, then the rear seal box and the glove box can be separated from the frame to expose the forming device, and then it is convenient to replace the mold of the forming device. After the mold is replaced, rotate the rear seal box in the reverse direction and slide the glove box in the reverse direction so that the glove box and the rear seal box are respectively installed on both sides of the frame, and the operation is simple and convenient.

[0046] Embodiment 1

[0047] This embodiment discloses a magnetic field forming press 1000. Referring to Figure 1 , the magnetic field forming press 1000 includes a frame 100, a powder weighing device 400, a powder feeding device 500, and a forming device 600. The forming device 600 is disposed on the frame 100, and the forming device 600 includes a mold for forming powder materials. The powder weighing device 400 is used to weigh a fixed amount of powder materials, and the powder feeding device 500 is used to transport the powder materials weighed by the powder weighing device 400 to the forming device 600.

[0048] A rear seal box 200 and a glove box 300 are connected to the frame 100. The rear seal box 200 is rotatably connected to one side of the frame 100 at the feeding end of the forming device 600, and the glove box 300 is slidably disposed on one side of the frame 100 at the discharging end of the forming device 600.

[0049] Among them, the powder weighing device 400 and the powder feeding device 500 are disposed in the rear seal box 200. The powder feeding device 500 can move along the rear seal box 200 to the mold of the forming device 600, and the powder feeding device 500 reciprocates above the forming device 600 to sprinkle the powder materials into the mold. The frame 100 is connected to the rear seal box 200 at the feeding end of the forming device 600. The powder weighing device 400 and the powder feeding device 500 are disposed in the rear seal box 200. After the powder weighing device 400 weighs a fixed amount of powder materials, it is loaded into the powder feeding device 500. The powder feeding device 500 transports the powder materials above the mold of the forming device 600 and reciprocates above the forming device 600 to evenly sprinkle the powder materials into the mold, so that there is no need to manually level the powder materials in the mold, which is convenient for the user to operate.

[0050] The glove box 300 is used for the user to operate to package the formed workpiece. In this embodiment, since the rear seal box 200 is rotatably connected to one side of the frame 100 at the feeding end of the forming device 600, and the glove box 300 is slidably disposed on one side of the frame 100 at the discharging end of the forming device 600, when it is necessary to replace the mold of the forming device 600, only by rotating the rear seal box 200 and sliding the glove box 300, the rear seal box 200 and the glove box 300 can be separated from the frame 100 to expose the forming device 600, thereby facilitating the replacement of the mold of the forming device 600. After the mold is replaced, rotate the rear seal box 200 in the reverse direction and slide the glove box 300 in the reverse direction so that the glove box 300 and the rear seal box 200 are respectively installed on both sides of the frame 100, and the operation is simple and convenient.

[0051] Specifically, referring to Figures 1 to 3, in this embodiment, a rotating shaft 110 is vertically arranged outside one side of the feeding end of the forming device 600 on the frame 100. A shaft sleeve 210 is arranged at the edge of the rear sealing box 200. A through hole that rotates in cooperation with the rotating shaft 110 is provided on the shaft sleeve 210. The frame 100 and the rear sealing box 200 are cooperated through the rotating shaft 110 and the shaft sleeve 210 to realize the rotational connection between the rear sealing box 200 and the frame 100. The rear sealing box 200 can rotate relative to the frame 100 around the rotating shaft 110 to open or close one side of the frame 100 located at the feeding end of the forming device 600. The connection strength between the frame 100 and the rear sealing box 200 is good and the installation is convenient.

[0052] Wherein, a first locking mechanism 220 for locking the rear sealing box 200 to the frame 100 is arranged on the rear sealing box 200. When the rear sealing box 200 rotates to close one side of the frame 100 located at the feeding end of the forming device 600, the rear sealing box 200 and the frame 100 are locked through the first locking mechanism 220. Thus, when the mold does not need to be replaced, the rear sealing box 200 is stably connected to the frame 100 so that the magnetic field forming press 1000 can work normally.

[0053] A traveling track 700 is arranged at the bottom of the glove box 300. The traveling track 700 is arranged on one side of the frame 100 located at the discharging end of the forming device 600. Specifically, in this embodiment, both the traveling track 700 and the frame 100 are fixed to the ground. A plurality of traveling wheels 310 are connected to the bottom of the glove box 300. The traveling wheels 310 are in rolling cooperation with the traveling track 700 and are guided through the traveling track 700. The glove box 300 realizes the sliding arrangement of the glove box 300 through the cooperation of the traveling rollers and the traveling track 700. Its structure is simple, the glove box 300 slides smoothly, and the installation is convenient.

[0054] Wherein, a second locking mechanism 320 for locking the glove box 300 to the frame 100 is arranged on the glove box 300. When the glove box 300 moves to close one side of the frame 100 located at the discharging end of the forming device 600, the second locking mechanism 320 locks the glove box 300 to the frame 100. Thus, when the mold does not need to be replaced, the glove box 300 is stably connected to the frame 100 so that the magnetic field forming press 1000 can work normally.

[0055] In this embodiment, both the first locking mechanism 220 and the second locking mechanism 320 are selected as locking buckles so as to quickly and labor-savingly realize the locking between the frame 100 and the rear sealing box 200, and between the frame 100 and the glove box 300. In addition, in other embodiments, the locking mechanism can also be a detachable connecting piece such as a bolt or a buckle.

[0056] Refer to Figure 1 and Figure 2, in this embodiment, the powder weighing device 400 is arranged above the powder feeding device 500 so as to drive the weighed powder into the powder feeding device 500 by gravity. The structure of the powder weighing device 400 is the same as that in the prior art, and it includes a powder discharging pipe, a powder hopper, a powder vibrating device and a powder weighing box. The powder material enters the powder weighing box through the powder discharging pipe and the powder hopper under the vibration of the powder vibrating device. After the powder weighing box weighs a fixed amount of powder material, the powder weighing box is driven by a cylinder connected to the powder weighing box to turn over so as to pour the weighed powder material into the powder feeding device 500.

[0057] Referring to Figures 1 to 6 , the powder feeding device 500 includes a material carriage 510, a driving electric cylinder 520 and a first support rail 530. The driving electric cylinder 520 is fixed in the rear sealing box 200, and the driving end of the driving electric cylinder 520 is connected to the material carriage 510. The first support rail 530 is arranged in the rear sealing box 200 and extends towards the forming device 600. The material carriage 510 is slidably engaged with the first support rail 530. The material carriage 510 is used for loading powder material and feeding the powder material into the mold. The driving electric cylinder 520 drives the material carriage 510 to move along the first support rail 530 to transport the powder material to the mold. When feeding the powder material into the mold, the driving electric cylinder 520 also facilitates controlling the material carriage 510 to reciprocate above the mold so as to make the powder material feeding more uniform.

[0058] Referring to Figure 6 and Figure 7 , the material carriage 510 includes a vehicle body 511, a powder box 512, a bottom plate 513 and an opening and closing cylinder 514. The vehicle body 511 is movably engaged with the first support rail 530. The powder box 512 is provided with an inner cavity for loading powder material. The powder box 512 is arranged in the vehicle body 511 and can move within the vehicle body 511. The bottom plate 513 is arranged at the bottom of the vehicle body 511. The cylinder body of the opening and closing cylinder 514 is fixed to the bottom plate 513, and the driving end of the opening and closing cylinder 514 is connected to the powder box 512. The powder box 512 can be driven by the opening and closing cylinder 514 to move relative to the bottom plate 513.

[0059] Referring to Figures 6 to 8 , wherein, both the upper sides of the powder box 512 and the vehicle body 511 are open so as to facilitate the powder weighing device 400 to pour the weighed powder material into the powder box 512. A material discharging opening 5121 communicating with its inner cavity is formed at the bottom of the powder box 512, and the material discharging opening 5121 abuts against the upper side of the bottom plate 513. A powder discharging opening 5133 is formed on the bottom plate 513, and the powder discharging opening 5133 is arranged in a staggered manner with the material discharging opening 5121. The opening and closing cylinder 514 can drive the powder box 512 to move until the material discharging opening 5121 is aligned with the powder discharging opening 5133.

[0060] When transporting powder materials, the bottom plate 513 fits against the material discharge opening 5121 at the bottom of the powder box 512 to close the powder box 512. When the material truck 510 moves above the mold, the opening and closing air cylinder 514 drives the powder box 512 to move, so that the material discharge opening 5121 is aligned with the powder outlet 5133, and the powder materials in the powder box 512 are scattered into the mold. Thus, when transporting powder materials, the powder materials in the powder box 512 are not easily spilled onto the first support track 530, ensuring the sanitation of the working environment of the material truck 510. It is not easy to affect the stable operation of the material truck 510 due to the spilled powder materials between the first support track 530 and the vehicle body 511. At the same time, compared with the conventional solution in which the powder box 512 of the material truck 510 directly contacts the track to close the material discharge opening 5121 of the powder box 512 through the track, in this solution, the powder box 512 does not contact the first support track 530, reducing the wear between the powder box 512 and the first support track 530.

[0061] In this embodiment, one first support track 530 is provided on each side of the vehicle body 511. Limit blocks 5111 are provided on the opposite outer sides of the vehicle body 511. The first support track 530 is provided with a sliding groove 800 that slidably cooperates with the limit blocks 5111. The first support track 530 is slidably matched with the limit blocks 5111 on the outer side of the vehicle body 511. By supporting the vehicle body 511 laterally through the first support track 530, the setting of the first support track 530 does not affect the lifting of the bottom plate 513.

[0062] Refer to Figure 5 and Figure 6 As shown in FIGS. [relevant figures], the frame 100 is fixedly provided with second support tracks 120 above the mold. Two second support tracks 120 are arranged in parallel, and the two second support tracks 120 are arranged in one-to-one correspondence with the two first support tracks 530. When the rear seal box 200 rotates to close the frame 100, the second support tracks 120 and the first support tracks 530 are arranged along the same straight line, and the material truck 510 can move from the first support track 530 to the second support track 120, so that the material truck 510 can walk above the mold to add powder materials to the mold.

[0063] Thus, through the segmented setting of the first support track 530 and the second support track 120, the first support track 530 and the second support track 120 do not affect the normal relative rotation of the rear seal box 200 with respect to the frame 100. At the same time, when powder feeding is required, the first support track 530 and the second support track 120 can support the material truck 510 to walk to the mold to add powder materials to the mold.

[0064] Among them, a sliding groove 800 that cooperates with the limit block 5111 is also provided on the second support rail 120 to achieve the sliding fit between the material truck 510 and the second support rail 120. One end of the sliding groove 800 on the second support rail 120 facing the first support rail 530 is in a flared shape like an eight-character, and one end of the sliding groove 800 on the first support rail 530 facing the second support rail 120 is in a flared shape like an eight-character, so as to facilitate the transfer of the material truck 510 between the first support rail 530 and the second support rail 120.

[0065] Referring to Figure 7 , the bottom plate 513 includes a lower friction plate 5131 and an upper friction plate 5132. The lower friction plate 5131 is arranged parallel to the lower side of the upper friction plate 5132. The powder box 512 is attached to the upper side of the upper friction plate 5132. The powder outlet 5133 penetrates through the lower friction plate 5131 and the upper friction plate 5132 at the same time. In this embodiment, the lower friction plate 5131 and the upper friction plate 5132 are made of different materials. Specifically, the lower friction plate 5131 is made of polytetrafluoroethylene, and the upper friction plate 5132 is made of stainless steel, thereby improving the wear resistance of the bottom plate 513 while meeting the structural strength of the bottom plate 513.

[0066] Referring to Figure 8 , a guiding slide rail 515 is arranged on the upper side of the bottom plate 513. The guiding slide rail 515 is arranged parallel to the opening and closing cylinder 514. A guiding block 5122 protrudes from the side of the powder box 512 in the direction facing the guiding slide rail 515. The guiding block 5122 is slidably fitted to the guiding slide rail 515, so that the opening and closing cylinder 514 can drive the powder box 512 to move along the bottom plate 513 more stably.

[0067] Referring to Figure 7 and Figure 8 , in this embodiment, the material truck 510 further includes a lifting cylinder 518. The lifting cylinder 518 is arranged vertically. The cylinder body of the lifting cylinder 518 is fixed to the vehicle body 511, and the driving end (i.e., the piston rod) of the lifting cylinder 518 is connected to the bottom plate 513. Since the cylinder body of the opening and closing cylinder 514 is fixed to the bottom plate 513, and the powder box 512 is fitted to the guiding slide rail 515 on the bottom plate 513 through the guiding block 5122, the lifting cylinder 518 can drive the bottom plate 513, the opening and closing cylinder 514 and the powder box 512 to lift synchronously.

[0068] When the skip car 510 transports powder materials, the lifting cylinder 518 drives the bottom plate 513, the powder box 512 on the bottom plate 513, and the opening and closing cylinder 514 to rise, making it difficult for the skip car 510 to interfere with the components in the rear seal box 200 and reducing the wear of the bottom plate 513. When the skip car 510 moves above the mold, the lifting cylinder 518 can drive the bottom plate 513, the powder box 512, and the opening and closing cylinder 514 to descend, making the bottom plate 513 fit above the mold, so that the powder materials will not leak outside the mold during the process of the powder materials being sprinkled into the mold, further ensuring the working environment hygiene of the magnetic field forming press 1000. Moreover, during the process of the skip car 510 repeatedly moving to sprinkle the powder materials into the mold, the bottom plate 513 that fits above the mold can level the upper side of the powder materials in the mold, reducing manual operation and improving the processing efficiency.

[0069] In this embodiment, one lifting cylinder 518 is provided at each of the four corners of the vehicle body 511, and the bottom plate 513 is driven to lift and lower synchronously by the four lifting cylinders 518, so that the bottom plate 513 is more stable when lifting and lowering. In addition, in other embodiments, the number of the lifting cylinders 518 can also be one or other appropriate numbers.

[0070] One end of the vehicle body 511 close to the forming device 600 is connected with a pneumatic gripper 516 and a mold release agent spray head 517. The mold release agent spray head 517 sprays the mold release agent in the mold to facilitate the demolding of the product after molding. The pneumatic gripper 516 can grip the demolded product, so that the formed product can be picked up and placed from the mold to the glove box 300 through the skip car 510, without setting an additional mechanism for gripping the product, further streamlining the magnetic field forming press 1000.

[0071] A tension spring 519 is connected between the vehicle body 511 and the bottom plate 513. The tension spring 519 is arranged on the side of the opening and closing cylinder 514 facing the powder box 512. A pulling force towards the vehicle body 511 direction is provided for the bottom plate 513 through the tension spring 519 to balance the force on the bottom plate 513. It is not easy for the bottom plate 513 to have a larger weight on the side close to the forming device 600 due to the cylinder body of the opening and closing cylinder 514 arranged on the side of the bottom plate 513 close to the forming device 600, and further cause the bottom plate 513 to tilt relative to the lifting cylinder 518 and affect the lifting and lowering of the lifting cylinder 518.

[0072] Embodiment 2

[0073] A magnetic field forming press of this embodiment is substantially the same as that in Embodiment 1, and the difference lies in:

[0074] In this embodiment, the rack 100 does not set the second support track 120 above the mold of the forming device 600.

[0075] Refer to Figure 9, in this embodiment, the first support rail 530 is movably arranged in the rear seal box 200. Specifically, at least one telescopic rail 900 is arranged outside the first support rail 530, and the telescopic rail 900 is connected to the inner wall of the rear seal box 200. In this embodiment, the telescopic rail 900 is arranged parallel to the outside of the first support rail 530, and the first support rail 530 is slidably engaged with the telescopic rail 900.

[0076] Thus, the first support rail 530 is telescopically arranged in the rear seal box 200 through the telescopic rail 900. When powder feeding is performed, the driving electric cylinder 520 drives the material vehicle 510 to move along the first support rail 530 in the direction close to the shaping device 600. The driving electric cylinder 520 can also drive the first support rail 530 to slide relative to the telescopic rail 900 through the material vehicle 510 so as to extend above the mold in the frame 100, so that the material vehicle 510 can walk above the mold to perform powder feeding. After the powder feeding is completed, the driving electric cylinder 520 drives the material vehicle 510 to move along the first support rail 530 in the direction away from the shaping device 600. The driving electric cylinder 520 also drives the first support rail 530 to slide relative to the telescopic rail 900 through the material vehicle 510 so as to retract into the rear seal box 200, so as to facilitate the relative rotation of the rear seal box 200 to the frame 100 to open the frame 100.

[0077] Among them, at least one telescopic rail 900 is arranged outside the first support rail 530. Specifically, in this embodiment, it is shown in the way that two telescopic rails 900 are arranged outside the first support rail 530, and the two telescopic rails 900 are sequentially stacked on the outside of the first support rail 530. Among them, the outermost telescopic rail 900 is fixedly connected to the inner wall of the rear seal box 200, and the other telescopic rail 900 is slidably arranged between the outermost telescopic rail 900 and the inner first support rail 530. Thus, when feeding, in addition to the first support rail 530 being able to slide and telescope relative to the telescopic rail 900, a telescopic rail 900 directly connected to the first support rail 530 can also telescope relative to the outermost telescopic rail 900. Thus, the length of the first support rail 530 can be further reduced while meeting the travel of the material vehicle 510, and further the length of the rear seal box 200 can be reduced.

[0078] In addition, in other embodiments, the telescopic rail 900 can also be set to other appropriate numbers. The specific setting method is that the outermost telescopic rail 900 is fixed to the rear seal box 200, and other telescopic rails 900 are sequentially stacked between the first support rail 530 and the outermost telescopic rail 900, and the telescopic rails 900 and between the telescopic rails 900 and the first support rail 530 are all slidably engaged.

[0079] The above are only the preferred embodiments of the present invention. Therefore, all equivalent changes or modifications made according to the structures, features and principles described in the scope of the present invention patent application are included in the scope of the present invention patent application.
