Description

Technical Field

[0001] This utility model relates to the field of neodymium iron boron processing technology, and in particular to a magnet slicing machine for processing neodymium iron boron magnets. Background Technology

[0002] Neodymium iron boron (NdFeB) magnetic materials, as the latest research achievement in the field of rare earth permanent magnet materials, are praised as the "King of Magnets" due to their excellent magnetic properties. This type of material is an alloy composed of elements such as praseodymium and neodymium metals and boron and iron, hence it is also called magnetic steel. NdFeB permanent magnets have extremely high magnetic energy product and coercivity. At the same time, due to their significant advantage of high energy density, they have been widely used in modern industrial and electronic technology fields. This makes it possible to miniaturize, lighten, and thin the instruments, electroacoustic motors, magnetic separation and magnetization equipment. The processing of NdFeB requires cutting the NdFeB blank into magnetic sheets of a specific thickness through a slicing process. For this purpose, a magnetic slicing machine for processing NdFeB magnets is used to solve this problem.

[0003] The cooling water pipes of existing slicing machines are usually connected by rigid pipes, which are difficult to remove once fixed. When the waste generated during cutting clogs the nozzle, it is necessary to disassemble and repair it, which is a complicated process and greatly affects the production process. When the equipment is cutting, the cooling water used for cutting and the waste generated will flow into the machine box. Traditional cutting machines are complicated to clean and require too many manual unblocking operations. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a magnet slicing machine for processing neodymium iron boron magnets, aiming to improve the problems of complex installation and maintenance of cooling water pipelines, inconvenient disassembly after nozzle blockage, and poor drainage and cumbersome cleaning caused by debris accumulation in the machine box in the existing technology.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A magnet slicing machine for processing neodymium iron boron magnets includes a machine casing. A water tank is fixedly connected to the bottom of the machine casing, and a baffle plate is fixedly connected to the front of the machine casing. Support plates are fixedly connected to both the left and right sides inside the machine casing. A guide plate is rotatably connected to the front of the support plate, and a steel wire is slidably connected to the outer periphery of the guide plate. Multiple evenly distributed support shafts are fixedly connected to the front of the inner side of the machine casing. Multiple evenly distributed fixing plates are fixedly connected to the front of the inner side of the machine casing. A fixing groove is opened on the top of the fixing plate. A fixing block is slidably connected inside the fixing plate. Rotating clips are rotatably connected to both the left and right sides of the top of the fixing plate. A water pipe is fixedly connected to the front of the fixing block, and multiple evenly distributed nozzles are fixedly connected to the bottom of the water pipe.

[0007] As a further description of the above technical solution:

[0021] This utility model has the following beneficial effects:

[0022] 1. In this utility model, by adopting a combination structure of a fixed plate, a fixed block and a rotating clip, the cooling water pipeline can be quickly disassembled and assembled. When the nozzle is blocked, the operator can directly pull out the fixed block along with the water pipe by loosening the rotating clip, thereby achieving a quick replacement effect without adjusting the pipeline layout, effectively improving production continuity.

[0023] 2. In this utility model, through the design of the guide plate, the guide channel, the filter plate and the inclined structure of the guide plate, an efficient automatic collection and filtration system for coolant and debris is constructed. The inclined guide plate causes the cutting debris and coolant to slide automatically down the guide channel to the drain hole under the action of gravity. The filter plate (21) with the sealed sliding structure of the telescopic groove separates the circulating coolant and impurities. When cleaning, only the filter plate needs to be pulled out for cleaning, which significantly reduces the operation and maintenance cost. Attached Figure Description

[0033] Reference Figure 1 and Figure 4In one embodiment of this utility model: a guide plate 17 is fixedly connected to the top inner side of the chassis 1. The guide plate 17 is inclined and fixedly connected to the rear of the baffle plate 13. The guide plate 17 is an inclined metal plate used to guide the coolant and debris generated during the cutting process to flow towards the drain hole 19, preventing arbitrary deposition inside the chassis 1. A guide groove 18 is opened at the top of the guide plate 17. The guide groove 18 mainly guides the coolant to form a directional flow, accelerating the accumulation of debris and coolant towards the drain hole 19 and improving the drainage efficiency. Multiple evenly distributed drain holes 19 are opened at the bottom inner side of the chassis 1. The drain holes 19 mainly prevent water accumulation at the bottom of the chassis 1 or the generation of water. Debris accumulates.

The height of the magnetic tray 15 can be adjusted by the hydraulic rods 16. The magnetic tray 15 is used to fix the NdFeB billet to be cut.

[0034] Working principle: When the nozzle 8 is clogged with debris, the operator can manually rotate the rotating clip 12 to disengage it from the fixing block 9 without tools. Utilizing the sliding fit between the fixing block 9 and the fixing plate 10, the water pipe 7, along with the nozzle 8, is vertically pulled out of the fixing groove 11. After cleaning, the rotating clip 12 is inserted back along the original path and pressed down. Rotating the rotating clip 12 to the top of the fixing block 9 completes the locking process, achieving a quick and sealed installation, significantly improving production flexibility. The coolant mixed with debris generated during the cutting process will converge in the guide groove 18 via the inclined guide plate 17. Under gravity, it flows along the groove to the drain hole 19 at the bottom of the casing 1. After the coolant mixed with debris is purified by the filter plate 21, the coolant enters the water tank 20 for recycling. The filter plate 21 is slidably connected to the telescopic groove 22 for seamless pulling, facilitating quick cleaning or replacement. After the equipment stops, the drain port 23 is opened, and the sediment is automatically discharged with the residual liquid under gravity, eliminating the need for manual cleaning inside the casing 1.
