Description

Technical Field

[0001] This utility model relates to the field of neodymium iron boron production technology, and in particular to a lifting platform for stacking neodymium iron boron billets. Background Technology

[0002] Neodymium iron boron (NdFeB) green blank stacking is a crucial transitional step in the preparation of magnetic materials. It is mainly used for preform preparation before static pressing. The specific process is as follows: the pressed NdFeB green blanks are loaded into rubber molds according to specifications and vacuum-packed in anti-oxidation packaging bags. Then, the packaged NdFeB green blanks (hereinafter referred to as encapsulated green blanks) are manually stacked in layers in a special isostatic pressing rack for stacking. The manual loading of encapsulated green blanks into the isostatic pressing rack is slow and inefficient. Moreover, the repetitive stacking operation can easily lead to worker fatigue, further reducing efficiency. Utility Model Content

[0003] In view of this, the present invention provides a lifting platform for stacking NdFeB green billets, which can overcome the disadvantages of manual loading of encapsulated green billets into isostatic pressing racks one by one, which is slow, inefficient, and the repetitive stacking operation can easily lead to worker fatigue, further reducing efficiency.

[0004] The technical solution is as follows: A lifting platform for stacking NdFeB green billets includes a base, support plates, guide rods, a lifting plate, a screw motor, a stepper motor, a rotating plate, a controller, an isostatic pressing rack, and a guiding mechanism. Support plates are connected to the top left and right sides of the base, and two guide rods are connected to each support plate. The lower ends of the guide rods are connected to the top of the base. The lifting plate is slidably connected to the four guide rods. A screw motor is installed on the left support plate, and the screw of the screw motor is rotatably connected to the top of the base. The screw of the screw motor is threadedly connected to the lifting plate. A stepper motor is installed at the bottom of the lifting plate, and a rotating plate is connected to the output shaft of the stepper motor. The rotating plate is located above the lifting plate. A controller is installed on the top of the right support plate. The screw motor and the stepper motor are electrically connected to the controller. The isostatic pressing rack is placed on the rotating plate. The guiding mechanism is used to guide the encapsulated green billets so that the encapsulated green billets can move into the isostatic pressing rack.

[0005] As a further preferred embodiment, the isostatic pressing rack consists of a first circular plate, a second circular plate, and a stop bar. The first and second circular plates are connected by a stop bar for blocking the encapsulated green blank. The front side of the first and second circular plates is not connected to the stop bar, forming a gap through which the encapsulated green blank moves onto the first circular plate.

[0006] As a further preferred embodiment, the guiding mechanism includes a mounting plate and a guide plate, with the mounting plate connected between two support plates, a guide rod passing through the mounting plate, and a guide plate for guiding the encapsulated green blank connected to the top of the mounting plate.

[0007] As a further preferred option, it also includes an arc-shaped slide rail, with the top of the lifting plate connected to the arc-shaped slide rail and the bottom of the rotating plate having an arc-shaped slide groove. The arc-shaped slide rail is located within the arc-shaped slide groove, and the arc-shaped slide rail and the arc-shaped slide groove slide in a sliding fit.

[0008] As a further preferred embodiment, it also includes a limiting post, with the top of the rotating plate connected to the limiting post, and a limiting hole opened on the first circular plate, with the limiting post located in the limiting hole.

[0009] As a further preferred option, a positioning ring is also included, with the top of the rotating plate connected to the positioning ring.

[0010] The beneficial effects are as follows: This utility model can guide the encapsulated green blanks through the guide plate, ensuring that the encapsulated green blanks can be moved into the isostatic pressing rack for stacking.

Detailed Implementation

[0018] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments, but this does not limit the scope of protection and application of the present invention.

[0019] refer to Figures 1-4 A lifting platform for stacking NdFeB green billets includes a base 1, support plates 2, guide rods 3, lifting plates 4, a screw motor 5, a stepper motor 6, a rotating plate 7, a controller 8, an isostatic pressing rack 9, and a guiding mechanism. Support plates 2 are bolted to the top left and right sides of the base 1. Two guide rods 3 are connected to the sides of the two support plates 2 that are close to each other. The lower ends of the guide rods 3 are connected to the top of the base 1. The two guide rods 3 on the same support plate 2 are arranged opposite each other. The lifting plate 4 is slidably connected to all four guide rods 3. A screw motor 5 is installed on the left support plate 2. The screw of the screw motor 5 is rotatably connected to the top of the base 1. The screw of the screw motor 5 is threadedly connected to the lifting plate 4. A stepper motor 6 is bolted to the middle of the front side of the bottom of the lifting plate 4. A rotating plate 7 is connected to the output shaft. The rotating plate 7 is located above the lifting plate 4. A controller 8 is installed in the middle of the top of the right support plate 2 by bolts. The lead screw motor 5 and the stepper motor 6 are both electrically connected to the controller 8. The isostatic pressing rack 9 is composed of a first circular plate 10, a second circular plate 11 and a stop bar 12. The stop bar 12 is connected between the first circular plate 10 and the second circular plate 11. The stop bars 12 are evenly spaced, and the front side of the first circular plate 10 and the second circular plate 11 is not connected to the stop bar 12, forming a gap. The encapsulated green blank can be moved to the first circular plate 10 through this gap. There is a lifting ring in the middle of the top of the second circular plate 11 to facilitate the lifting of the isostatic pressing rack 9. The guiding mechanism is used to guide the encapsulated green blank so that the encapsulated green blank can be moved into the isostatic pressing rack 9.

[0020] refer to Figure 3 The guiding mechanism includes a mounting plate 13 and a guide plate 14. The upper part of the two support plates 2 is connected to the mounting plate 13 by bolts. The guide rod 3 passes through the mounting plate 13. The top left and right sides of the mounting plate 13 are connected to the guide plate 14 by bolts. A guiding channel is formed between the two guide plates 14. The notch of the isostatic pressing rack 9 is aligned with the guiding channel between the two guide plates 14.

[0021] The operator places the isostatic pressing rack 9 onto the rotating plate 7, aligning the notch of the rack 9 with the guide channel between the two guide plates 14. Then, the controller 8 controls the screw motor 5, which moves the lifting plate 4 upwards. The lifting plate 4 then moves the first circular plate 10 upwards, making the top of the first circular plate 10 flush with the top of the mounting plate 13. An external conveying device and a pushing cylinder are then installed in front of the mounting plate 13. The conveying device is arranged parallel to the mounting plate 13, and the pushing cylinder is arranged perpendicular to the mounting plate 13. The conveying device transports the encapsulated green blank to... Approaching the guide plate 14, the encapsulated green preform is pushed from front to back between the two guide plates 14 by the pushing cylinder. The guide plates 14 guide the encapsulated green preform to prevent its position from shifting. The pushing cylinder continues to push the encapsulated green preform to the rear inside the isostatic pressing rack 9 for stacking. Then, the operator controls the output shaft of the stepper motor 6 to rotate via the controller 8, causing the rotating plate 7 to rotate to the right. The rotating plate 7 causes the isostatic pressing rack 9 to rotate to the right, aligning the guide channel between the two guide plates 14 with the left side inside the isostatic pressing rack 9, thus pushing the encapsulated green preform into the isostatic pressing rack. Inside the isostatic pressing rack 9, on the left side, the operator controls the output shaft of the stepper motor 6 to rotate in the opposite direction via the controller 8, causing the rotating plate 7 to rotate to the left. The rotating plate 7 then causes the isostatic pressing rack 9 to rotate to the left, aligning the guide channel between the two guide plates 14 with the inside right side of the isostatic pressing rack 9. The encapsulated green preform is then pushed to the inside right side of the isostatic pressing rack 9. Then, the operator controls the output shaft of the stepper motor 6 to rotate via the controller 8, causing the isostatic pressing rack 9 to rotate to the right, aligning the guide channel between the two guide plates 14 with the inside front side of the isostatic pressing rack 9. The encapsulated green preform is then pushed to the inside front side of the isostatic pressing rack 9, and the green preform is stacked in one go. One layer of encapsulated green billets is stacked, and the operator controls the screw motor 5 via the controller 8. The screw motor 5 drives the lifting plate 4 to move downward, and the lifting plate 4 drives the first circular plate 10 to move downward. The first circular plate 10 is lowered a certain distance, and the second layer of encapsulated green billets is stacked. The above operation is repeated until the isostatic pressing rack 9 is full of encapsulated green billets. The stacking is automatic, which can reduce manual intervention and improve work efficiency. When the isostatic pressing rack 9 is full of encapsulated green billets, it can be lifted from the rotating plate 7 by hoisting and moved to the isostatic pressing equipment for subsequent isostatic pressing treatment.

[0022] refer to Figure 5 and Figure 6 It also includes an arc-shaped slide rail 15. The top front and rear sides of the lifting plate 4 are connected to the arc-shaped slide rail 15. The bottom front and rear sides of the rotating plate 7 are provided with arc-shaped slide grooves 16. The arc-shaped slide rail 15 is located in the arc-shaped slide groove 16, and the arc-shaped slide rail 15 and the arc-shaped slide groove 16 slide in cooperation. The arc-shaped slide rail 15 and the arc-shaped slide groove 16 can guide the rotating plate 7 and improve the stability of the rotating plate 7.

[0023] refer to Figure 2 and Figure 5 It also includes limit posts 17. The top of the rotating plate 7 is connected to three limit posts 17. The distribution of the three limit posts 17 is irregular. The first circular plate 10 has three limit holes 18. The distribution of the three limit holes 18 is irregular. The limit posts 17 and the limit holes 18 correspond one-to-one. The limit posts 17 are located inside the limit holes 18.

[0024] refer to Figure 5 It also includes a positioning ring 19, which is connected to the top of the rotating plate 7.

[0025] The operator places the isostatic pressing rack 9 onto the rotating plate 7. The positioning ring 19 can position the isostatic pressing rack 9 to ensure the accuracy of its position. If the notch of the isostatic pressing rack 9 is not aligned with the guide channel between the two guide plates 14, the top of the limiting post 17 will contact the bottom of the first circular plate 10. At this time, the operator can rotate the isostatic pressing rack 9. The distribution of the three limiting posts 17 and the three limiting holes 18 is irregular. Only when the notch of the isostatic pressing rack 9 is aligned with the guide channel between the two guide plates 14 will the limiting post 17 be inserted into the limiting hole 18. This ensures that the notch of the isostatic pressing rack 9 can be aligned with the guide channel between the two guide plates 14, and the limiting post 17 can limit the isostatic pressing rack 9 to prevent it from rotating.
