Description

Technical Field

[0001] This invention belongs to the field of neodymium iron boron magnet processing technology, specifically relating to a suspended transfer device for neodymium iron boron production. Background Technology

[0002] Neodymium iron boron (NdFeB) permanent magnets are widely used in new energy vehicles, wind power generation, energy-saving home appliances, and electronic information due to their excellent magnetic properties. In the manufacturing process of NdFeB sintered magnets, cold isostatic pressing and drying are two crucial steps: the green blank formed by magnetic field molding has a low density and exhibits a density gradient, requiring cold isostatic pressing for uniform pressure from all directions to further increase density and eliminate density inconsistencies; the surface of the isostatically pressed blank and the gaps in the vacuum packaging contain residual hydraulic oil and moisture, which must be thoroughly removed through a drying process before proceeding to the subsequent sintering process to avoid defects such as bubbles, peeling, and cracking during sintering.

[0003] Currently, the production organization methods for isostatic pressing and drying processes in the industry are generally quite traditional and outdated. In the isostatic pressing stage, single-layer baskets are typically used to load the billets. The packaged billets are manually placed one by one into the baskets, which are then manually stacked onto ordinary transfer trolleys. A simple hoist is then manually operated to lift the stacked baskets into the isostatic pressing cylinder in batches. The drying stage typically uses independent box-type drying ovens or intermittent mesh belt drying lines. After isostatic pressing, the billets must be manually unloaded from the baskets, transferred, and reloaded before entering the drying equipment.

[0004] The aforementioned existing technology has the following significant drawbacks: single-layer material baskets are scattered and stacked on the trolley, lacking an effective fixing structure. During the workshop transfer process, they are prone to shaking, slipping, or even tipping over, which not only causes the billet to be bumped and broken, and the vacuum packaging to be damaged, oxidized, and scrapped, but also poses a serious safety hazard of injuring personnel. Summary of the Invention

[0005] In view of this, the present invention discloses a suspended transfer device for NdFeB production, the purpose of which is to solve the problem of single-layer material baskets being scattered and stacked on the trolley without an effective fixing structure.

[0006] To achieve the above objectives, the present invention provides the following technical solution: A suspended transfer device for NdFeB production includes a top plate and a bottom plate. Several sets of material baskets are arranged between the top plate and the bottom plate. Each material basket includes a rectangular grid plate. Connecting seats are detachably connected to both ends of the grid plate. Support rods parallel to the end faces of the grid plate are horizontally fixed inside each connecting seat. Four rectangularly distributed columns are fixed between the top plate and the bottom plate. Each column has a vertically arranged through slot. The ends of the support rods extend into the corresponding through slots and are slidably connected thereto. A locking structure is provided between the support rods and the through slots to restrict their sliding. Four connecting parts for connecting to a crane are provided at the top of the top plate.

[0007] This solution employs a multi-layer integrated structure, enabling batch transfer of multiple layers of billets in a single hoisting operation. This replaces the traditional single-layer basket method of sequential handling, significantly reducing the number of hoisting operations and transfer time. The overhead crane uses four connecting components on the top plate to grip the billets as a whole, achieving continuous transfer from the isostatic pressing station to the drying station without touching the ground. This results in tight process connections, a fast production cycle, and a significant improvement in overall flow efficiency. Furthermore, the grid plate and connecting seat are detachable, allowing for quick installation or removal without disassembling the main frame. The number of basket layers can be freely configured according to the production batch size, providing good capacity adaptability. The absence of grid plates in empty layers reduces the overall weight of the basket and the load on the overhead crane. Simultaneously, through the sliding engagement of the support rods along the column slots, each layer of baskets can move up and down independently and lock. This allows for flexible adjustment of the interlayer distance according to different height specifications of NdFeB billets, ensuring safe placement of the billets and full utilization of vertical space. One set of transfer devices is compatible with various sizes of billets, offering strong versatility and reducing tooling change costs.

[0008] Furthermore, each of the through slots has a parallel guide slot on the side away from the grid plate, and each guide slot has a plurality of positioning slots on its sidewall; the support rod is hollow inside, and the locking structure includes a guide sleeve horizontally and vertically fixed to the corresponding end of the support rod, the guide sleeve extending into the corresponding guide slot, and a positioning slider is slidably connected coaxially inside each guide sleeve, and an elastic reset element is provided between the positioning slider and the guide sleeve, and both ends of the positioning slider are arc-shaped; a cylindrical rotating shaft is rotatably connected coaxially inside the support rod, and both ends of the rotating shaft have receiving slots corresponding to the positioning slider, and the end of the positioning slider away from the guide slot passes through the support shaft and extends into the corresponding receiving slot.

[0009] This solution employs a top-down, layer-by-layer loading method where all grid plates are stacked and gathered at the top. This ensures that each layer of billet is unobstructed by the upper basket, providing ample operating space and visibility. This facilitates the placement of billets by operators or robotic arms, resulting in high loading convenience, precise billet positioning, and effectively reducing the risk of damage during loading. It is particularly suitable for loading large and heavy billets. Secondly, the curved end-face positioning slider, combined with the elastic reset component, creates a damping descent effect. When the grid plate slides down after unlocking, the positioning slider bounces and engages sequentially in the positioning slots, generating continuous sliding resistance to limit the descent speed. This prevents the basket from falling too quickly due to its own weight and avoids direct impact between the grid plate and the already loaded billets, ensuring product safety. It also reduces operational impact and extends the equipment's lifespan. Furthermore, the rotating shaft-driven locking structure enables rapid unlocking and locking. Simply rotating the shaft completes the locking and releasing process, making operation convenient, positioning quick, and layer spacing adjustment highly efficient.

[0010] Furthermore, the material basket also includes several positioning structures. Each positioning structure includes a base with a slot at its bottom for engaging with the reinforcing ribs of the grid plate. A retaining plate, which movably fits against the reinforcing ribs, is movably disposed within the slot. A connecting screw, the end of which is rotatably connected to the retaining plate, is threaded onto one side of the base. A horizontally arranged elastic telescopic rod is fixed to the end of each elastic telescopic rod, and a vertically arranged positioning plate is fixed to the end of each elastic telescopic rod. Each positioning plate has a through slot, within which a load-bearing plate is horizontally arranged, with the height of the through slot exceeding the thickness of the load-bearing plate. One end of the load-bearing plate is vertically slidably connected to the base, and an elastic reset element is disposed between the load-bearing plate and the base. A lower wedge-shaped block is disposed at the bottom of the positioning plate on the side furthest from the base, and an upper wedge-shaped block is disposed on the lower end face of the load-bearing plate. The inclined surfaces of the lower and upper wedge-shaped blocks are opposite each other.

[0011] In this design, the base of the positioning structure adopts a clamping installation using a slot, a clamping plate, and a screw. Its position can be adjusted arbitrarily along the grid plate and ribs, and it can be quickly locked in place. It can flexibly adapt to billets of different sizes and specifications, offering strong tooling versatility. After installation, a gravity-driven wedge block transmission structure is used. The billet placement action itself triggers the positioning plate to automatically retract outwards, eliminating the need for manual operation and an additional power source. This achieves passive, automated positioning and retraction, completing billet placement and retraction in one step, resulting in high loading efficiency. Simultaneously, the wedge block inclined surface transmission smoothly converts the billet's weight into horizontal retraction displacement. The retraction process is smooth and controllable. Combined with the buffer damping formed by the elastic reset component and the elastic telescopic rod, the overall smoothness of the movement is further improved, preventing billet instability.

[0012] Furthermore, the load-bearing plate is fixed with a vertically arranged upper adjusting screw, and the top of the upper wedge block is threadedly connected to the bottom of the upper adjusting screw; the bottom of the positioning plate is fixed with a horizontally arranged lower adjusting screw, and the side wall of the lower wedge block is threadedly connected to the end of the lower adjusting screw.

[0013] Furthermore, the top of the positioning plate is bent toward the base.

[0014] Furthermore, both the lower wedge block and the upper wedge block have ceramic wear-resistant plates on their inclined surfaces.

[0015] Furthermore, a fixed shaft is fixed between the ends of the two horizontally adjacent support rods, and a connecting groove for accommodating the fixed shaft is provided on the column.

[0016] Other advantages, objectives, and features of the invention will be set forth in the following description and will be apparent to those skilled in the art in some respects, or may be learned by practice of the invention. The objectives and other advantages of the invention can be realized and obtained through the following description. Attached Figure Description

Detailed Implementation

[0019] like Figures 1-5 As shown: A suspended transfer device for NdFeB production includes a top plate 1 and a bottom plate 2. Several sets of material baskets are arranged between the top plate 1 and the bottom plate 2. Each material basket includes a rectangular grid plate 3. Connecting seats 4 are detachably connected to both ends of the grid plate 3. Support rods 5 parallel to the end faces of the grid plate 3 are horizontally fixed inside each connecting seat 4. Four rectangularly distributed columns 6 are fixed between the top plate 1 and the bottom plate 2. Each column 6 has a vertically arranged through groove. The ends of the support rods 5 extend into the corresponding through grooves and are slidably connected thereto. A locking structure is provided between the support rods 5 and the through grooves to restrict their sliding. Four connecting parts 7 for connecting to a crane are provided at the top of the top plate 1.

[0020] In use, the spacing between each basket and the total number of baskets should be pre-adjusted according to the height and dimensions of the NdFeB billet to be transferred and the production batch. When adjusting the spacing, loosen the locking mechanism between the support rod 5 and the through slot of the column 6, hold the basket and slide it vertically along the column 6. The support rod 5 will move up and down along the through slot, causing the grid plate 3 and connecting seat 4 to rise and fall synchronously. After adjusting to the target spacing, operate the locking mechanism to lock and fix the support rod 5, and the basket will be positioned at the current height. To increase or decrease the number of baskets, separate the support rod 5 from the connecting seat 4 to remove the grid plate 3; to add baskets, fix both ends of the grid plate 3 to the corresponding connecting seat 4.

[0021] After adjusting the number and spacing of the material baskets, the packaged NdFeB blanks are placed layer by layer on the grid plates 3. After loading, the gantry crane's gripping mechanism docks with the four connecting parts 7 at the top of the top plate 1 (the docking of the gantry crane's gripping mechanism with the connecting parts 7 is a conventional technical method, so it is not described in detail), and the entire suspended transfer device is lifted as a whole, transferred along the track to the top of the vertical isostatic press, and lowered into the cylinder for isostatic pressing.

[0022] This solution employs a multi-layer integrated structure, enabling batch transfer of multiple layers of billets in a single hoisting operation. This replaces the traditional single-layer basket method of sequential handling, significantly reducing the number of hoisting operations and transfer time. The overhead crane uses the top plate 1 and four connecting components 7 to grip the billets as a whole, achieving continuous transfer from the isostatic pressing station to the drying station without touching the ground. This results in a compact process flow, fast production cycle, and a significant improvement in overall efficiency. Furthermore, the grid plate 3 and connecting seat 4 are detachably connected, allowing for quick installation or removal without disassembling the main frame. The number of basket layers can be freely configured according to the production batch size, providing good capacity adaptability. The absence of the grid plate 3 in empty layers reduces the overall weight of the basket and the load on the overhead crane. Simultaneously, through the sliding engagement of the support rod 5 along the through groove of the column 6, each layer of baskets can move up and down independently and be locked. This allows for flexible adjustment of the interlayer distance according to NdFeB billets of different heights and specifications, ensuring safe placement of the billets and full utilization of vertical space. One set of transfer devices is compatible with various sizes of billets, offering strong versatility and reducing tooling replacement costs.

[0023] Furthermore, each of the through grooves has a parallel guide groove on the side away from the grid plate 3, and each guide groove has a plurality of positioning grooves 8 on its sidewall; the support rod 5 is hollow inside, and the locking structure includes a guide sleeve 9 horizontally and vertically fixed to the corresponding end of the support rod 5, the guide sleeve 9 extending into the corresponding guide groove, and a positioning slider 10 is coaxially slidably connected inside each guide sleeve 9, and an elastic reset member 11 is provided between the positioning slider 10 and the guide sleeve 9, and both ends of the positioning slider 10 are arc-shaped; a cylindrical rotating shaft 12 is coaxially rotatably connected inside the support rod 5, and both ends of the rotating shaft 12 have receiving grooves 13 corresponding to the positioning slider 10, and the end of the positioning slider 10 away from the guide groove passes through the support rod 5 and extends into the corresponding receiving groove 13.

[0024] Before loading the blank, slide all the grid plates 3 of the material baskets upward along the through groove of the column 6, and stack them all at the upper end below the top plate 1, so that there is enough operating space above the bottom material basket. During loading, the basket is lowered layer by layer from top to bottom: The rotating shaft 12 inside the corresponding layer's support rod 5 is rotated, aligning the receiving grooves 13 at both ends of the rotating shaft 12 with the positioning slider 10. Under the action of the elastic reset member 11, the positioning slider 10 retracts inward, and its outer end exits the positioning groove 8 on the side wall of the guide groove, releasing the basket from locking. Then, the mesh plate 3 of that layer is pushed downward, the support rod 5 slides down along the through groove, and the guide sleeve 9 moves down synchronously along the guide groove. During the downward movement, the arc-shaped end of the positioning slider 10 slides past the opening of each positioning groove 8 in sequence, repeatedly extending and retracting under the push of the elastic reset member 11, forming damping resistance and limiting the downward speed, allowing the mesh plate 3 to descend slowly and uniformly. When the target loading height is reached, the rotating shaft 12 is rotated in the opposite direction, the receiving grooves 13 are misaligned, and the cylindrical surface of the rotating shaft 12 pushes the positioning slider 10 outward. The outer end of the positioning slider 10 is engaged in the corresponding positioning groove 8, achieving rapid locking. The mesh plate 3 of that layer... That is, it is fixed at the current height.

[0025] After locking, place the NdFeB blanks on the grid plate 3. After loading, unlock and lower the next material basket in the same way, lowering and loading layer by layer until all layers are loaded. When unloading, reverse the operation, unlocking and moving the basket upwards layer by layer to retract it.

[0026] In this scheme, the entire grid plate 3 is stacked and folded at the top, and loaded layer by layer from top to bottom. This ensures that each layer of billet is unobstructed by the upper material basket, providing ample operating space and a clear field of vision. This facilitates the placement of billets by operators or robotic arms, resulting in high loading convenience, precise billet positioning, and effectively reducing the rate of damage from impacts during loading. It is particularly suitable for loading large-sized and heavy billets. Secondly, the positioning slider 10 with its arc-shaped end face, in conjunction with the elastic reset component 11, creates a damping and slow-descent effect. When the grid plate 3 slides down after unlocking, the positioning slider 10 bounces and engages sequentially in the positioning slots 8, generating continuous sliding resistance, limiting the downward speed, preventing the material basket from falling too quickly due to its own weight, and avoiding direct impact of the grid plate 3 on the already loaded billets below, ensuring product safety, reducing operational impact, and extending the service life of the equipment. At the same time, the locking structure driven by the rotating shaft 12 enables quick unlocking and locking. Rotating the rotating shaft 12 completes locking and releasing, making operation convenient, positioning rapid, and layer spacing adjustment highly efficient.

[0027] Furthermore, the material basket also includes several positioning structures, each including a base 14. The base 14 has a slot at its bottom for engaging with the reinforcing ribs of the grid plate 3. A clamping plate 15, which is movably disposed within the slot and fits against the reinforcing ribs of the grid plate 3, is also present. A connecting screw 16, with its end rotatably connected to the clamping plate 15, is threaded onto one side of the base 14. Horizontally arranged elastic telescopic rods 17 are fixed to the other side of the base 14. Vertically arranged positioning plates 18 are fixed to the ends of the elastic telescopic rods 17. Each positioning plate 18 has a through slot, within which a load-bearing plate 19 is horizontally arranged. The height of the through slot is greater than the thickness of the load-bearing plate 19. One end of the load-bearing plate 19 is vertically slidably connected to the base 14, and an elastic reset member 11 is disposed between the load-bearing plate 19 and the base 14. A lower wedge block 21 is disposed at the bottom of the positioning plate 18 on the side away from the base 14. The lower end face is provided with an upper wedge block 20, and the lower wedge block 21 is arranged opposite to the inclined surface of the upper wedge block 20.

[0028] When installing the positioning structure, align the slot at the bottom of the base 14 with the rib plate of the grid plate 3 and insert it, so that the rib plate is embedded in the slot. Tighten the connecting screw 16 on one side of the base 14. The connecting screw 16 pushes the clamping plate 15 to move towards the rib plate until the clamping plate 15 is tightly against the side of the rib plate. The base 14 is fixed to the rib plate by the clamping force, so that multiple positioning structures form a positioning clamp for the blank. Tighten the connecting screw 16 in the opposite direction to release the clamp and readjust the position of the base 14.

[0029] When the billet is loaded, the bottom surface of the billet first contacts the top surface of the load-bearing plate 19, and presses down on the load-bearing plate 19 under the action of gravity. The load-bearing plate 19 slides down along the vertical guide rail of the base 14, and the elastic reset member 11 is compressed. During the downward movement of the load-bearing plate 19, the upper wedge block 20 on its lower end face moves down accordingly. The inclined surface of the upper wedge block 20 contacts and squeezes against the inclined surface of the lower wedge block 21 on the inner bottom of the positioning plate 18, decomposing the vertical pressure into a horizontal thrust, pushing the positioning plate 18 to move horizontally towards the base 14, compressing the elastic telescopic rod 17, and the positioning plate 18 gradually retracts outward. When the load-bearing plate 19 slides down to the lower limit position, the positioning plate 18 retracts to the outermost position, and a uniform expansion gap is formed between the side of the billet and the positioning plate 18, completing the automatic retraction. After the blank is removed, the elastic reset component 11 pushes the load-bearing plate 19 to rise, the elastic telescopic rod 17 pushes the positioning plate 18 to reset inward, the two wedge blocks return to their initial relative positions, and the positioning structure returns to its initial positioning state.

[0030] In this design, the base 14 of the positioning structure is installed using a clamping method with a slot and a clamping plate 15 and a screw. It can be adjusted to any position along the grid plate 3 and quickly locked in place, which can flexibly adapt to blanks of different sizes and specifications, and the tooling is highly versatile. After installation, a gravity-driven wedge block transmission structure is used. The blank placement action itself can trigger the positioning plate 18 to automatically retract outward, without manual operation or additional power source, realizing passive automated positioning and retraction. The blank placement and retraction are completed in one step, resulting in high loading efficiency. At the same time, the wedge block inclined surface transmission smoothly converts the weight of the blank into horizontal retraction displacement. The retraction process is smooth and controllable. Combined with the buffer damping formed by the elastic reset member 11 and the elastic telescopic rod 17, the smoothness of the overall action is further improved, and the instability of the blank is avoided.

[0031] Furthermore, the load-bearing plate 19 is fixed with a vertically arranged upper adjusting screw 22, and the top of the upper wedge block 20 is threadedly connected to the bottom of the upper adjusting screw 22; the bottom of the positioning plate 18 is fixed with a horizontally arranged lower adjusting screw 23, and the side wall of the lower wedge block 21 is threadedly connected to the end of the lower adjusting screw 23.

[0032] In this solution, by rotating the upper wedge block 20 and the lower wedge block 21, the initial relative position and extrusion stroke of the two inclined surfaces can be flexibly adjusted, thereby precisely controlling the horizontal retraction amount of the positioning plate 18. This can adapt to the different requirements of expansion gap for different specifications of blanks, further improving the versatility and adaptation accuracy of the positioning components. At the same time, after the wedge blocks wear out due to long-term use, wear compensation can be performed by adjusting the screw to maintain a stable retraction stroke and extend service life.

[0033] Furthermore, the top of the positioning plate 18 is bent toward the base 14.

[0034] The top of the positioning plate 18 is bent toward the base 14 to form an inward flange structure. When the billet is lowered for loading, the bent slope can act as a guide, guiding the billet to slide smoothly into the positioning area for quick centering and positioning. At the same time, the bent edge can limit the billet from moving upward and falling out due to shaking or vibration during transportation, thus improving loading stability. In addition, the top bend is equivalent to forming a reinforcing flange on the upper part of the positioning plate 18, which can enhance the structural rigidity of the positioning plate 18 itself and reduce bending deformation when subjected to pressure.

[0035] Furthermore, both the lower wedge block 21 and the upper wedge block 20 have ceramic wear-resistant plates on their inclined surfaces (this is a conventional technical method, so it is not shown in the figure).

[0036] By setting ceramic wear-resistant plates, the wear of the lower wedge block 21 and the upper wedge block 20 is reduced.

[0037] Furthermore, a fixed shaft 24 is fixed between the ends of the two horizontally adjacent support rods 5, and a connecting groove for accommodating the fixed shaft 24 is provided on the column 6.

[0038] Two horizontally adjacent support rods 5 are fixedly connected at their ends by a fixed shaft 24, so that the support rods 5 on both sides of the same layer of the basket form a synchronous and linked overall frame structure. During the lifting process, the two ends move synchronously, avoiding unilateral deviation and jamming, and the sliding is more stable and smooth. The column 6 has a corresponding connecting groove to accommodate the fixed shaft 24. The fixed shaft 24 slides synchronously with the support rod 5 along the connecting groove, which further increases the guide support points, improves the stability and structural rigidity of the basket lifting, and prevents the grid plate 3 from twisting and deforming under load.

[0039] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made to it in form and detail without departing from the scope defined by the claims of the present invention.
