Description

Technical Field

[0001] The present invention relates to the field of neodymium iron boron processing, and particularly relates to a processing device for neodymium iron boron pressing. Background Art

[0002] Neodymium iron boron contains a large amount of rare earth element neodymium, as well as iron and boron. Its characteristics are hard and brittle. Since the surface is extremely easy to be oxidized and corroded, neodymium iron boron must be subjected to surface coating treatment. Surface chemical passivation is one of the good solutions. As a kind of rare earth permanent magnet material, neodymium iron boron has extremely high magnetic energy product and coercivity. At the same time, the advantage of high energy density enables neodymium iron boron permanent magnet materials to be widely used in modern industry and electronic technology.

[0003] During the processing and forming process of neodymium iron boron, the moving stability of the existing processing equipment for pressing processing is relatively low, and after the pressing processing is completed, it is not convenient to take out the pressed workpiece, and the operation difficulty is relatively large. Therefore, there is a new type of pressing processing equipment for neodymium iron boron products with the patent number CN213635692U to solve the above problems. However, this equipment has the following defects when in use, such as: the fixed processing seat can only process products with the same specification, shape and size, and cannot process products with different specifications, thus limiting its scope of application. Summary of the Invention

[0004] The purpose of the present invention is to provide a processing device for neodymium iron boron pressing.

[0005] The technical problems of the present invention are mainly solved by the following technical solutions:

[0006] A processing device for neodymium iron boron pressing, including a machine box provided with a switch door:

[0007] A support plate for fixing a cylinder is arranged in the machine box, wherein a die cylinder with both upper and lower ends open is screwed to the cylinder, and a bottom plate for sealing the bottom openings of the cylinder and the die cylinder is fixed to the bottom of the box body through a hydraulic rod I. A locking mechanism for supporting the bottom plate is arranged in the box body below the support plate, and an extrusion mechanism facing the die cylinder is arranged in the box body above the support plate;

[0008] The locking mechanism includes U-shaped rods arranged in the openings of two C-shaped rods connected to the support plate on both sides of the bottom plate, and the bottom end surfaces of the U-shaped rods are abutted against the bottom end surface of the bottom plate. A convex seat is arranged at the bottom of the bent part of the U-shaped rod, and a lead screw driven by a motor is arranged on the convex seat;

[0009] The extrusion mechanism includes a mounting plate driven by a hydraulic rod II. A stud is provided at the bottom of the mounting plate, and a pressing die located directly above the opening of the die barrel is screwed to the bottom end of the stud. Slide bars are vertically arranged on both sides of the mounting plate. A pulley set corresponding to the slide bars is provided at the end of the mounting plate, and the pulley grooves in the pulley set are buckled on the corresponding slide bars.

[0010] Preferably, a base is provided at the bottom of the box body. A receiving groove for accommodating the hydraulic rod I is provided on the base. An inclined surface is inclined downward on one side of the top of the base. A communication port communicating with the aggregate box outside is provided on the side wall of the box body at the bottom end of the inclined surface. An electromagnet arranged on the same side is provided on the inner wall of the box body above the communication port.

[0011] Preferably, the output shaft of the hydraulic rod I is located within the opening of the U-shaped rod.

[0012] Preferably, the convex seat is located between one set of C-shaped rods and the corresponding inner wall of the box body.

[0021] The technical solution of the present invention will be further specifically described below through embodiments in conjunction with the drawings.

[0022] A processing device for neodymium iron boron pressing includes a chassis 1 provided with a switch door:

[0023] A support plate 2 for fixing the cylinder 3 is arranged in the chassis 1. The cylinder 3 is screwed with a die cylinder 4 that is open at both the upper and lower ends. The bottom of the box body 1 is fixed with a bottom plate 5 that seals the bottom openings of the cylinder 3 and the die cylinder 4 through a hydraulic rod I 6. A locking mechanism 7 for supporting the bottom plate 5 is arranged in the box body 1 below the support plate 2, and an extrusion mechanism 8 facing the die cylinder 4 is arranged in the box body 1 above the support plate 2;

[0024] The locking mechanism 7 includes C-shaped rods 71 arranged on both sides of the bottom plate 5 and connected to the support plate 2. A U-shaped rod 72 that abuts against the bottom end face of the bottom plate 5 is arranged in the openings of the two groups of C-shaped rods 71. The output shaft of the hydraulic rod I 6 is located in the opening of the U-shaped rod 72, and a convex seat 73 is arranged at the bottom of the bent part of the U-shaped rod 72. A lead screw 74 driven by a motor 75 is arranged on the convex seat 73. As Figure 1 、 2 shown, the convex seat 73 is located between the inner wall of one group of C-shaped rods 71 corresponding to the box body 1. Bearings for fixing the lead screw 74 are arranged on the C-shaped rods 71 and the side wall of the box body 1, and a cross bar 14 passing through the through hole on the convex seat 73 is also arranged on the C-shaped rods 71 and the side wall of the box body 1;

[0025] The extrusion mechanism 8 includes a mounting plate 82 driven by a hydraulic rod II 81. A stud 83 is arranged at the bottom of the mounting plate 82, and a press mold 84 located directly above the opening of the die cylinder 4 is screwed to the bottom end of the stud 83. Slide bars 85 are vertically arranged on both sides of the mounting plate 82, and the two ends of the slide bars 85 are fixedly connected between the support plate 2 and the inner top wall of the box body 1 respectively. A pulley block 86 corresponding to the slide bars 85 is arranged at the end of the mounting plate 82, and the pulley grooves in the pulley block 86 are buckled on the corresponding slide bars 85.

[0026] A base 9 is provided at the bottom of the box body 1. A receiving groove for receiving the hydraulic rod I6 is provided on the base 9. One side of the top of the base 9 is inclined downward to form an inclined surface 10. A communication port 11 communicating with the aggregate box 12 outside is provided on the side wall of the box body 1 at the lowermost end of the inclined surface 10. An electromagnet 13 arranged on the same side is provided on the inner wall of the box body 1 above the communication port 11.

[0027] In this embodiment, the top surface of the bottom plate 5 abuts against the bottom end surfaces of the cylinder 3 and the die cylinder 4, and the top end of the die cylinder 4 is lower than the horizontal plane of the top end of the cylinder 3.

[0028] As Figure 1 、 2 As shown in 3 and 4, during use, a die cylinder 4 of a corresponding specification is selected according to the size and shape, and it is screwed and fixed to the cylinder 3. At this time, the bottom plate 5 abuts against the bottom ends of the cylinder 3 and the die cylinder 4. At the same time, a pressing die 84 of a corresponding size is screwed to the stud 83. Then, after the switch door is opened, the raw material is introduced into the die cylinder 4. The hydraulic rod II81 drives the mounting plate 82 to drive the pressing die 84 to move down into the die cylinder 4 to extrude and form the product. When the mounting plate 82 moves up and down, it will drive the pulley block 86 to slide on the slide bar 85. By means of the slide bar 85 abutting against the pulley block 86, the situation that the mounting plate 82 swings during the up and down movement can be effectively prevented, so that the extrusion mechanism 8 moves linearly up and down and is also convenient for its movement.

[0029] During the above process, the hydraulic rod I6 drives the bottom plate 5 to seal the bottom opening of the die cylinder 4 to prevent the raw material from falling. In order to share the pressure caused by the extrusion mechanism 8 on the hydraulic rod I6 through the bottom plate 5 during extrusion molding, at this time, the U-shaped rod 72 mounted on the two C-shaped frames 71 can effectively share the impact force caused by the bottom plate 5 on the hydraulic rod I6 to ensure the sealing performance of the bottom opening of the die cylinder 4 by the bottom plate 5.

[0030] After forming, the motor 75 drives the lead screw 74 to rotate in the screw hole on the convex seat 73, thereby driving the convex seat 73 to move to the right. At this time, the convex seat 73 drives the U-shaped rod 72 to move to the right, so that its left end slides out from the left C-shaped rod 71 and moves to the right side of the bottom plate 5. Among them, the hydraulic rod II 81 drives the pressing die 84 to extrude the product in the die barrel 4 so that it slides out from the bottom opening of the die barrel 4. At this time, the hydraulic rod I 6 drives the bottom plate 5 and the pressing die 84 to move downward at the same speed, so that while the product can be extruded from the die barrel 84, it can also ensure that the product will not fall on the bottom plate 5. When the pressing die 84 resets upward and the bottom plate 5 drives the product to move above the base 9, at this time, the electromagnet 13 is energized to work, and the magnetic attraction generated by it will force the product to slide leftward from the bottom plate 5. When most of the bottom end of the product slides out of the bottom plate 5, it will fall and drop onto the inclined surface 10 under the influence of gravity, rather than sliding to the electromagnet 13 and being adsorbed and fixed to it. Finally, the product flows into the aggregate box 12 through the communication port 11. Among them, a buffer layer needs to be provided on components such as the inclined surface 10 to buffer and protect the dropped product.

[0031] The above has described the present invention in detail, but the content described is only the preferred embodiment of the present invention and cannot be considered as used to limit the scope of implementation of the present invention. All equal changes and improvements made according to the scope of the application of the present invention should still fall within the scope covered by the patent of the present invention.
