Description

Technical Field

[0001] The utility model belongs to the technical field of square magnetic powder core processing, and in particular relates to a square magnetic powder core forming mechanism. Background Art

[0002] The preparation process of the sendust magnetic powder core is as follows: unannealed soft magnetic silicon aluminum powder and insulating material are evenly mixed in a solvent of 1%-8% of the weight of the soft magnetic alloy powder, annealed at high temperature, and an insulating coating layer with a thickness of less than 100 nanometers is formed on the surface of the sendust magnetic aluminum soft magnetic alloy powder. Due to the effect of high temperature, there will be a slight bonding effect between the insulating layers. The powder is simply broken up, mixed with a special lubricant for powder molding, and pressed under a pressing pressure of 78 tons to obtain a standard 270 ring to obtain the sendust magnetic powder core.

[0003] The pressing and forming of square magnetic powder cores requires a magnetic powder core forming machine. The magnetic powder core forming machine of traditional technology consists of a fixed die and a movable die. The fixed die is fixed on the lower die seat, and the movable die is pushed down by a hydraulic cylinder and cooperates with the fixed die. The defect of this magnetic powder core forming machine is that the pressed square magnetic powder core is sleeved on the outside of the fixed die head, and needs to be picked up automatically by a robot or manually picked up and unloaded. The processing speed is slow, which affects the production efficiency. Utility Model Content

[0004] In order to make up for the shortcomings of the prior art and solve the problem that the traditional technology requires manual or mechanical picking up of materials, the utility model proposes a square magnetic powder core forming mechanism.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0009] The lower die seat is set as a fixed die, and the square die head lifted by the lifting hydraulic cylinder constitutes a floating middle die. The lifting hydraulic cylinder lifts the square die head upward, and the upper die pressed downward cooperates with the square die head and the lower die seat to press the square magnetic powder core into shape. After forming, the hydraulic rod of the lifting hydraulic cylinder is recovered, driving the square die head to move down and flush with the surface of the lower die seat, so that the formed square magnetic powder core can be pushed out through a pushing mechanism;

[0010] Preferably, the bottom thread of the lower die seat is butt-jointed with an annular ring, and a guide groove for guiding the sliding of the push block is fixedly provided on the annular ring.

[0011] The guide groove cooperates with the push block to slide in the guide groove. This structural design can effectively guide the moving track of the square die head and avoid the deviation of the square die head on the lower die base.

[0012] Preferably, the limit block is limited at the bottom of the lower die base. By limiting the limit block at the bottom of the lower die base, the position of the square die head is ensured to be stable, the error and adjustment time are reduced, and the production efficiency is improved.

[0013] Preferably, guide rails are provided on both sides of the guide groove, and slide grooves cooperating with the guide rails are provided on both sides of the push block, which can effectively guide the moving track of the square die head and avoid the deviation of the square die head on the lower die base.

[0014] Preferably, limit plates are provided on both sides of the top of the lower die seat, and U-shaped guide grooves are opened on the limit plates.

[0015] Preferably, a bracket is provided on the support, and a push cylinder connected to the pushing block is fixedly provided on the bracket, and the formed square magnetic powder core is pushed and unloaded from the lower die seat by the push cylinder.

[0016] The push cylinder and the push block constitute a pushing mechanism for pushing the formed square magnetic powder core to be unloaded from the lower die seat. The push block translates along the U-shaped guide grooves on the limit plates on both sides of the lower die seat. Under the action of the push cylinder, the formed square magnetic powder core is stably pushed out from the lower die seat.

[0017] Preferably, an inclined blanking plate is provided on the side of the lower die base away from the push cylinder, and a hollow hole is provided on the inclined blanking plate. A waste material receiving trough is placed below the inclined blanking plate at the bottom of the support.

[0018] The hollow holes are used to allow the residual waste powder to automatically fall due to gravity, so that the waste powder passes through the hollow holes and falls into the waste material receiving trough.

[0019] Compared with the prior art, the technical effects and advantages of the utility model are:

[0020] The square magnetic powder core forming mechanism uses a lifting hydraulic cylinder to push the square die head to cooperate with the pressing upper die to press the magnetic powder core into shape. At the same time, the pushing mechanism is used to push the formed square magnetic powder core to unload the material, which reduces the need for manual or manipulator picking up the unloaded material, reduces the risk of workers directly contacting the mold and the material, improves safety, has a high degree of automation, is easy to operate, improves production efficiency, has a simple structure, is easy to manufacture and maintain, reduces manual intervention, and reduces the risk of contamination that may be caused by human factors.

[0028] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] The following is combined with Figure 1-5 To further explain this application in detail,

[0030] The embodiment of the present application discloses a square magnetic powder core forming mechanism, comprising a lower die base 1, wherein the lower die base 1 is fixedly connected to a support 3 through four support rods 2 at the bottom thereof, and a floating middle die 4 is provided on the support 3;

[0031] The floating middle die 4 comprises a lifting hydraulic cylinder 5, a push block 6 threadedly connected to the top of the lifting hydraulic cylinder 5, a limit block 7 fixed to the top of the push block 6, and a square die head 8 fixed to the top of the limit block 7;

[0032] The lifting hydraulic cylinder 5 pushes the square die head 8 through the through hole 9 on the lower die base 1 and extends to the top of the lower die base 1 , and the square magnetic powder core is pressed and formed on the lower die base 1 through the cooperation between the square die head 8 and the upper die pressing downward.

[0033] The lower die base 1 is set as a fixed die, and the square die head 8 lifted by the lifting hydraulic cylinder 5 constitutes a floating middle die 4. The lifting hydraulic cylinder 5 lifts the square die head 8 upward, and the upper die pressed downward cooperates with the square die head 8 and the lower die base 1 to press the square magnetic powder core into shape. After forming, the hydraulic rod of the lifting hydraulic cylinder 5 is recovered, driving the square die head 8 to move downward and be flush with the surface of the lower die base 1, so that the formed square magnetic powder core can be pushed and discharged through a pushing mechanism;

[0034] Compared with the traditional technology that requires manual or robotic picking up and unloading, the use of this mechanism can reduce the need for manual or robotic picking up and unloading, thereby reducing the risk of workers directly contacting molds and materials and improving safety. Due to the increased degree of automation, the mechanism is more operable and can significantly improve production efficiency. Since only one pushing mechanism is required to complete the unloading, the processing speed is faster, which further improves production efficiency. The entire mechanism has a simple structure and is easy to manufacture and maintain, reducing manual intervention and reducing the risk of contamination due to human factors.

[0035] The bottom thread of the lower die base 1 is connected with an annular ring 10, and a guide groove 11 is fixedly provided on the annular ring 10 to guide the sliding of the push block 6. The existence of the annular ring 10 can provide a more stable thread connection, enhance the structural stability of the bottom, and ensure that the fixed connection of the lower die base 1 is firm and reliable. The guide groove 11 can slide in the guide groove 11 in cooperation with the push block 6. This structural design can effectively guide the moving trajectory of the square die head 8, avoid the deviation of the square die head 8 on the lower die base 1, and ensure the accuracy and consistency of molding. The establishment of the annular ring 10 and the guide groove 11 can provide more precise positioning, ensure the correct connection between the square die head 8 and the upper die pressed downward, thereby improving the processing accuracy.

[0036] The limit block 7 is limited at the bottom of the lower die base 1, and the position of the square die head 8 is ensured to be stable by limiting the limit block 7 at the bottom of the lower die base 1, reducing errors and adjustment time, and improving production efficiency. Guide rails 12 are provided on both sides of the guide groove 11, and slide grooves 13 that cooperate with the guide rails 12 are provided on both sides of the push block 6. The moving track of the square die head 8 can be effectively guided to avoid the deviation of the square die head 8 on the lower die base 1.

[0037] Limiting plates 14 are provided on both sides of the top of the lower die base 1, and U-shaped guide grooves 15 are opened on the limiting plates 14. Pushing blocks 16 that cooperate with the U-shaped guide grooves 15 for sliding guidance and push the formed square magnetic powder core on the top of the lower die base 1 to be discharged. A bracket 17 is provided on the support 3, and a horizontal push cylinder 18 connected to the pushing block 16 is fixed on the bracket 17. The formed square magnetic powder core is pushed and discharged from the lower die base 1 through the horizontal push cylinder 18.

[0038] The push cylinder 18 and the push block 16 constitute a pushing mechanism for pushing the formed square magnetic powder core to be discharged from the lower die seat 1. The push block 16 translates along the U-shaped guide grooves 15 on the limit plates 14 on both sides of the lower die seat 1. Under the action of the push cylinder 18, the formed square magnetic powder core is stably pushed and discharged from the lower die seat 1, ensuring the stability and consistency of the pushing process.

[0039] By adopting the design of the limit plate 14 and the U-shaped guide groove 15, the push block 16 is effectively guided during the pushing process, reducing the friction and collision with the lower die base 1, reducing the potential risk of damage, and extending the service life of the equipment. The use of the push cylinder 18 and the push block 16 as the pushing mechanism can achieve fast and stable pushing and unloading of the formed square magnetic powder core, greatly improving production efficiency, saving time and labor costs, and through the automated pushing mechanism, no human intervention is required, the operation is simple and convenient, reducing misoperation and errors caused by human operation, and improving the accuracy and consistency of the work.

[0040] A side of the lower die base 1 away from the horizontal push cylinder 18 is provided with an inclined blanking plate 19 , and a hollow hole 20 is provided on the inclined blanking plate 19 . A waste material receiving trough 21 located below the inclined blanking plate 19 is placed at the bottom of the support 3 .

[0041] The hollow hole 20 is used to automatically drop the residual waste powder due to gravity, so that the waste powder passes through the hollow hole 20 and falls into the waste receiving trough 21. This design can easily collect the waste, reduce the scattering and handling difficulty of the waste, and the formed square magnetic powder core will not fall from the hollow hole 20, but will be discharged from the inclined discharge plate 19 to the receiving platform. By automatically dropping and centrally collecting the waste, the time and labor intensity of manual waste cleaning are reduced, thereby improving production efficiency.

[0042] The working process of the square magnetic powder core forming mechanism is as follows:

[0043] 1. In the initial state, the lower die base 1 is fixedly connected to the support 3, and the floating middle die 4 is located above the lower die base 1.

[0044] 2. The lifting hydraulic cylinder 5 pushes the square die head 8 through the through hole 9 on the lower die base 1 and extends to the top of the lower die base 1.

[0045] 3. The square magnetic powder core is pressed and formed on the lower die seat 1 by cooperating with the square die head 8 and the upper die pressing downward.

[0046] 4. After the molding is completed, the hydraulic rod of the jacking hydraulic cylinder 5 is retracted, driving the square die head 8 to move down and be flush with the surface of the lower die base 1.

[0047] 5. The pushing mechanism (the push cylinder 18 and the pushing block 16) pushes the formed square magnetic powder core to be unloaded.
