Description

Technical Field

[0001] This utility model relates to the technical field of neodymium iron boron permanent magnet production equipment, specifically to a pusher device for sintering neodymium iron boron permanent magnets. Background Technology

[0002] In the production process of neodymium iron boron (NdFeB) permanent magnet materials, the formed NdFeB permanent magnets need to be precisely numbered and loaded into specially designed material trays to ensure the smooth progress of subsequent processing. This process not only requires a high degree of accuracy but also needs to consider the safety and stability of the permanent magnets in the material trays during transportation and storage.

[0003] Currently, the commonly used technical process in the industry is as follows: First, a certain number of NdFeB molded bodies are loaded into material trays according to predetermined specifications; then, these material trays filled with molded bodies are sent to a storage warehouse for temporary storage until they accumulate to a preset batch size or meet specific production needs. However, in the process of transferring the material trays from the storage warehouse to a transfer vehicle for the next stage of transportation, the existing technology has revealed significant limitations and shortcomings.

[0004] Specifically, because the connecting channels or equipment between storage warehouses and transfer vehicles often lack automated or semi-automated conveying devices, the transfer of material pallets relies heavily on manual operation. Workers need to manually remove each pallet from the storage warehouse and push it into the transfer vehicle. This process presents several key problems:

[0005] Heavy workload: Especially for material trays far from the work side, due to their remote location, limited visibility, and difficulty in effectively transferring force, workers need to exert more physical strength and energy to complete the pushing task, which greatly increases the workload and labor intensity.

[0006] High safety risks: When manually pushing the material tray, improper control, such as excessive force or directional deviation, can easily cause the tray to collide with the transfer vehicle or other equipment, leading to the collapse, cracking, or even breakage of the NdFeB molded parts. This not only affects the product yield but may also pose a threat to the safety of workers.

[0007] Inefficient: The manual pushing method is not only time-consuming and labor-intensive, but also makes it difficult to ensure the continuity and efficiency of the transfer process, thus limiting the automation level and production efficiency of the entire production process. Utility Model Content

[0008] The purpose of this invention is to provide a pusher device for sintering NdFeB permanent magnets, so as to solve the technical problems pointed out in the background art.

[0009] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0010] A pusher device for sintering NdFeB permanent magnets is installed above a storage bin. It includes connecting beams arranged parallel to each other in a front-to-back direction. The connecting beams are fixed directly above the storage bin. A fixing plate is horizontally fixed between the two connecting beams. A lifting cylinder is installed on the fixing plate. The output shaft of the lifting cylinder moves vertically through the fixing plate. The lower end of the output shaft of the lifting cylinder is fixedly connected to the lifting plate. Pushing mechanisms for pushing the material tray are fixedly connected to both ends of the lifting plate.

[0011] Furthermore, the pushing mechanism includes a cylinder connecting plate fixedly connected to the end of the lifting plate. The cylinder connecting plate is horizontally arranged, and a cylinder fixing block is fixedly connected to one end of the cylinder connecting plate. A pushing cylinder is fixedly connected to the cylinder connecting plate along its length direction. The end of the pushing cylinder is fixedly connected to the cylinder fixing block. The rod of the pushing cylinder extends movably out of the cylinder fixing block, and a cushioning rubber pad is fixedly connected to the end of the rod of the pushing cylinder.

[0012] Furthermore, a plurality of guide rods are vertically arranged on the lifting plate, and the guide rods are movably guided through the fixed plate. The fixed plate is correspondingly provided with bushings that cooperate with the guide rods.

[0013] Furthermore, L-shaped fixing blocks are provided at both ends of the connecting beam for easy fixing, and fixing holes are pre-set on the L-shaped fixing blocks.

[0014] Furthermore, the material tray is transported to the storage bin via a conveying mechanism.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] This utility model's pusher device precisely controls the position of the material tray by using a lifting cylinder to drive a lifting plate and its pushing mechanism. The pushing cylinder, in conjunction with a buffer pad, ensures the smooth pushing of the tray. Its working principle is highly efficient and precise, not only reducing the burden of manual operation but also preventing damage to the tray caused by direct collisions. This effectively improves the automation level of the production line and product quality, while simultaneously enhancing production efficiency and safety. Attached Figure Description

[0023] like Figure 1As shown, a pusher device for sintering NdFeB permanent magnets is installed above a storage bin. It includes connecting beams 1 arranged parallel to each other in a front-to-back direction. The connecting beams 1 are fixed directly above the storage bin. A fixing plate 3 is horizontally fixed between the two connecting beams 1. A lifting cylinder 4 is installed on the fixing plate 3. The output shaft of the lifting cylinder 4 moves vertically through the fixing plate 3. The lower end of the output shaft of the lifting cylinder 4 is fixedly connected to a lifting plate 5. Both ends of the lifting plate 5 are fixedly connected to a pushing mechanism for pushing the material tray 12. The pushing mechanism includes a cylinder connecting plate 8 fixedly connected to the end of the lifting plate 5. The cylinder connecting plate 8 is horizontally arranged, and a cylinder fixing block 9 is fixedly connected to one end of the cylinder connecting plate 8. A pushing cylinder 10 is fixedly connected to the cylinder connecting plate 8 along its length. The end of the pushing cylinder 10 is fixedly connected to the cylinder fixing block 9, and the rod of the pushing cylinder 10 extends movably out of the cylinder fixing block 9. A cushioning rubber pad 11 is fixedly connected to the end of the rod of the pushing cylinder 10. Several guide rods 6 are vertically arranged on the lifting plate 5. The guide rods 6 movably guide and pass through the fixing plate 3. A bushing 7 corresponding to the guide rods 6 is arranged on the fixing plate 3.

[0024] Specifically, as shown in the figure, the two ends of the connecting beam 1 are provided with L-shaped fixing blocks 2 for easy fixing, and the L-shaped fixing blocks 2 are pre-set with fixing holes.

[0025] Specifically, as shown in the figure, the material tray 12 is conveyed to the storage bin by a conveying mechanism.

[0026] Specifically, the specific implementation principle of this utility model is as follows:

[0027] Initial state: The pusher device is stationary, the lifting cylinder 4 is not activated, and the lifting plate 5 and its pushing mechanism are at their highest point, away from the material tray 12 in the storage bin. The guide rod 6 ensures the stable vertical movement of the lifting plate 5 through the bushing 7.

[0028] Lifting Start: When it is necessary to move the material tray 12, the lifting cylinder 4 starts to work, and its output shaft moves vertically downward, driving the lifting plate 5 and all components fixed to it (including the pushing mechanism and guide rod 6) to descend together. The guide rod 6 slides smoothly in the bushing 7 to ensure the stability of the lifting process.

[0029] Preparation for pushing: As the lifting plate 5 descends, the pushing mechanism fixed at both ends of the lifting plate 5 gradually approaches the material tray 12. At this time, the pushing cylinder 10 is in standby mode, its air rod is not extended, and the rubber pad 11 maintains a certain distance from the material tray 12.

[0030] Pushing action: When the lifting plate 5 descends to the set position, that is, when the rubber pad 11 at the end of the push cylinder 10 contacts or nearly contacts the material tray 12, the push cylinder 10 starts to work. The rod extends forward, generating thrust through the contact surface between the rubber pad 11 and the material tray 12, pushing the material tray 12 towards the target position. The design of the rubber pad 11 provides a cushioning effect, avoiding damage that may be caused by direct collision.

[0031] Adjustment and Repetition: Depending on actual needs, the material tray 12 may be pushed to different positions within the storage bin. After one push is completed, the lifting cylinder 4 and the pushing cylinder 10 can reverse as needed, returning the pushing device to its initial position, ready for the next push operation. Simultaneously, the conveying mechanism continues to operate, transporting new or pending material trays 12 into the storage bin, awaiting the next push.

[0032] Fixing and Stability: The entire pusher device is securely mounted directly above the storage compartment via the connecting beam 1 and the L-shaped fixing block 2, ensuring the stability and reliability of the device during operation. The fixing holes on the L-shaped fixing block 2 facilitate connection with the storage compartment or other fixed structures, increasing the overall structural stability.

[0033] This utility model's pusher device precisely controls the position of the material tray by using a lifting cylinder to drive a lifting plate and its pushing mechanism. The pushing cylinder, in conjunction with a buffer pad, ensures the smooth pushing of the tray. Its working principle is highly efficient and precise, not only reducing the burden of manual operation but also preventing damage to the tray caused by direct collisions. This effectively improves the automation level of the production line and product quality, while simultaneously enhancing production efficiency and safety.

[0034] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.

[0035] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
