Technical Field

[0001] The utility model relates to the technical field of permanent magnet production, in particular to a magnetic field press capable of rapidly producing axially oriented permanent magnets. Background Art

[0002] Permanent magnets are magnets that can maintain their magnetism for a long time. They are a very important magnetic material with strong magnetic force and magnetization ability. The production process of permanent magnets includes raw material preparation, molding, sintering, magnetization and other links.

[0003] In the production of permanent magnets, magnetic powder is usually mixed with an organic binder and then pressed into a desired shape by pressure. The formed permanent magnet is then solidified.

[0004] The authorization announcement number in the prior art is: CN219986167U, and the name is a magnetic field forming press. The device proposed in the patent document drives the upper pressure plate and the pressure head to move downward and be inserted into the forming groove of the lower pressure seat through a hydraulic cylinder. It can simultaneously pressure-form multiple columnar products, and the formed permanent magnets are flipped and unloaded through a subsequent flipping device. However, in the actual application of permanent magnet production, although the device can facilitate the press forming and unloading of multiple permanent magnets, it still needs to be flipped and reset after the permanent magnets are flipped and unloaded before the subsequent pressure forming of the permanent magnets is carried out, which has poor production efficiency for the permanent magnets. Utility Model Content

[0005] The technical problem solved by the utility model is that the production efficiency of permanent magnets in the prior art is poor, and a magnetic field press is provided which can quickly produce axially oriented permanent magnets.

[0006] In order to solve the above technical problems, the utility model provides a magnetic field press that can quickly produce axially oriented permanent magnets, including a frame, a flip mechanism is provided inside the frame, the flip mechanism includes a flip plate, and forming molds respectively installed on the front and back of the flip plate; the flip mechanism also includes support components located at the four corners below the flip plate, the support components are used to support the flip plate after it is flipped horizontally; the inner top wall of the frame is provided with a pressure forming component, the pressure forming component includes a lower pressure mold directly above the forming mold, and the lower pressure mold is used to extrude the material through the forming mold.

[0007] Preferably, the flipping mechanism also includes a first rotating rod and a second rotating rod respectively fixed on the left and right surfaces of the flip plate and rotatably cooperated with the inner wall of the frame. The outer surface of the frame is fixedly connected to a servo motor, and the output shaft of the servo motor rotates through the outer surface of the frame and is fixedly connected to the first rotating rod. By setting up the servo motor, the output shaft of the servo motor drives the first rotating rod to rotate, so that the first rotating rod drives the flip plate and the second rotating rod to rotate synchronously, thereby facilitating the flipping of the flip plate, and then facilitating the unloading of the pressure-formed permanent magnet after flipping.

[0008] Preferably, the flipping mechanism also includes a support column fixed to the bottom wall of the frame and facing the two directions of the flipping plate and respectively cooperating with the first rotating rod and the second rotating rod. By setting the support column, not only the first rotating rod and the second rotating rod can be limited and stabilized, but also the flip plate can provide a supporting effect when the permanent magnet is pressure-formed.

[0009] Preferably, the support assembly includes two reciprocating screws that are rotatably engaged with the inner wall of the frame, and a reciprocating wire seat that is threadably engaged with the reciprocating screws. The side surfaces of the two reciprocating wire seats that are close to each other are fixedly connected to support plates, and the support plates are located at the four corners below the flip plate. By setting the reciprocating screws, a cycle of the reciprocating thread opened on the outer surface of the reciprocating screw is set to be the same as the 180-degree flip of the flip plate, so that when the flip plate is flipped to 90 degrees, the reciprocating wire seat can move to the other end at the reciprocating screw, so that the reciprocating wire seat drives the two sets of support plates away from each other.

[0010] Preferably, the support assembly also includes a first sprocket fixed to the outer surface of the first rotating rod and the second rotating rod, and a second sprocket fixed to the outer surface of the reciprocating screw rod.

[0011] Preferably, a sliding bar is fixedly connected to the inner bottom wall of the frame, and the outer surface of the sliding bar slides with the support plate; a steel plate is provided inside the flip plate, and by providing the sliding bar, the support plate can be better facilitated to limit the sliding, thereby avoiding the risk of the support plate deflecting and shaking during movement.

[0012] Preferably, the pressure forming assembly also includes a hydraulic cylinder fixed to the top wall of the frame, and a connecting plate fixedly connected to the output end of the hydraulic cylinder and connected to the down-pressing mold, the connecting plate is used for installing or disassembling the down-pressing mold; the connecting block on the outer surface of the connecting plate is fixedly connected to the limiting rod, and the upper end of the limiting rod slides through the inner top wall of the frame and is fixedly connected to a retaining ring. By setting a hydraulic cylinder, the output end of the hydraulic cylinder pushes the connecting plate and the down-pressing mold to press downward, so that the down-pressing mold can extrude the material stored in the flip plate, thereby completing the extrusion molding of the permanent magnet.

[0013] Preferably, the outer surface of the second rotating rod is fixedly connected to the limit plate, and the inner side wall of the frame is fixedly connected to two limit bars that are engaged with the limit plate. The limit bars are used to limit the horizontal position of the flip plate after flipping through the limit plate. By setting the limit plate, the limit bar can be used to limit the flip plate when it flips, thereby facilitating the stable flipping of the flip plate to 180 degrees.

[0014] Compared with the related art, the present invention has the following beneficial effects:

[0015] 1. The utility model is provided with a pressure forming component, which can extrude and form the material stored in the flip plate facing upward, and after forming, the flip plate is driven to flip through the flip mechanism to flip the material for flipping and unloading. After flipping, the lower flip plate can be flipped to the upper part synchronously, so that the positions of the two flip plates are switched, and then the material is put into the flip plate facing upward after the conversion for re-extrusion molding, thereby eliminating the trouble of pouring and then resetting the material. In addition, the support component can support and stabilize the flip plate after flipping, thereby greatly improving the production efficiency of permanent magnets.

[0016] 2.

By providing a support column, not only the first rotating rod and the second rotating rod can be limited and stabilized, but also the flip plate can provide a supporting effect when the permanent magnet is pressure-formed. By providing a slide bar, it is better to facilitate the limited sliding of the support plate, thereby avoiding the risk of the support plate offsetting and shaking during movement. By providing a hydraulic cylinder, the output end of the hydraulic cylinder pushes the connecting plate and the pressing die to press down, so that the pressing die can extrude and form the material stored in the flip plate.

[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

The permanent magnet can be continuously extruded through the flip plate 203 on the other side, which greatly improves the production efficiency of the permanent magnet.

[0028] The flipping mechanism 2 also includes a first rotating rod 202 and a second rotating rod 204 respectively fixed on the left and right surfaces of the flip plate 203 and rotatingly cooperating with the inner wall of the frame 1. The outer surface of the frame 1 is fixedly connected to the servo motor 201, and the output shaft of the servo motor 201 rotates through the outer surface of the frame 1 and is fixedly connected to the first rotating rod 202.

[0029] By setting up a servo motor 201, the output shaft of the servo motor 201 drives the first rotating rod 202 to rotate, so that the first rotating rod 202 drives the flip plate 203 and the second rotating rod 204 to rotate synchronously, thereby facilitating the flip plate 203 to be flipped, and then facilitating the unloading of the pressure-formed permanent magnet after flipping.

[0030] Furthermore, the positions of the two flip plates 203 can be switched after flipping, thereby eliminating the need for frequent resetting after unloading and then performing the tedious permanent magnet pressure forming operation, thereby greatly improving production efficiency.

[0031] The flipping mechanism 2 also includes a support column 205 fixed to the inner bottom wall of the frame 1 and facing the two directions of the flip plate 203 and rotating with the first rotating rod 202 and the second rotating rod 204 respectively. By setting the support column 205, not only can the first rotating rod 202 and the second rotating rod 204 be limited and stabilized, but the flip plate 203 can also provide a supporting effect during the pressure forming of the permanent magnet, thereby improving the stability and practicality of the entire device during the processing and production of permanent magnets.

By providing the slide bar 2013, it is possible to better facilitate the limited sliding of the support plate 209, thereby avoiding the risk of deviation and shaking of the support plate 209 during movement, greatly improving the stability of the movement of the support plate 209, and further improving the support stability of the support plate 209 on the flip plate 203.

[0038] The inner top wall of the frame 1 is provided with a pressure forming assembly, which includes a lower pressing die 5 facing the upper side of the forming die 206 . The lower pressing die 5 is used for extruding the material through the forming die 206 .

[0039] refer to Figures 1 to 4 The setting of the pressure forming assembly can push the pressing die 5 so that the pressing die 5 is aligned with the material in the flip plate 203, so that the pressing die 5 can extrude the material.

[0042] The outer surface of the second rotating rod 204 is fixedly connected to the limit plate 8, and the inner side wall of the frame 1 is fixedly connected to two limit bars 9 that are clamped with the limit plate 8. The limit bars 9 are used to limit the horizontal position of the flip plate 203 after flipping through the limit plate 8.

[0043] By setting the limit plate 8, the limit stop rod 9 can be used to limit and block the flip plate 203 when it flips, so that the flip plate 203 can be stably flipped to 180 degrees, so that the flip plate 203 can be accurately flipped to the bottom of the pressing mold 5, and the flip plate 203 is positioned and aligned with the pressing mold 5, which facilitates the stable production of permanent magnets.
