[0023] Example:
[0024] See also Figure 1-Figure 5 As shown, a magnetic core pressing and forming device comprises a workbench 1, a column 2 is vertically fixed to the rear side of the upper surface of the workbench 1, a suspended beam 3 is arranged on the front side of the top of the column 2, a pressing cylinder 4 is fixed to the front side of the top of the suspended beam 3, an extrusion head 5 is downwardly mounted on the output end of the pressing cylinder 4, the pressing cylinder 4 is vertically arranged so that the extrusion head 5 can only move in the vertical direction, and the extrusion head 5 is placed below the suspended beam 3, a boss 6 is arranged on the upper surface of the workbench 1, a mounting ring 7 is fixed on the top of the boss 6, a limiting groove 8 is provided at the center of the upper surface of the boss 6, the limiting groove 8 is arranged front and back, a turntable 9 is rotatably mounted on the surface of the mounting ring 7, and a rotating plate 9 is arranged at the bottom of the turntable 9. The ring grooves of the mounting ring 7 cooperate with each other so that the turntable 9 can only rotate along the rotation axis. Extended suspended plates 10 are provided at the front and rear of the upper surface of the turntable 9. A forming mold 11 is plugged into and out of the surface of the extended suspended plate 10. The forming mold 11 can be quickly disassembled and installed with the extended suspended plate 10. The extended suspended plate 10 is provided with a through hole. A fixing pin is provided on the lower surface of the forming mold 11. During installation, the fixing pin is removed into the through hole to maintain the installation of the forming mold 11. The suspended support can push up the fixing pin from below when the forming mold 11 is disassembled. When the forming mold 11 is rotated to the rear side, it is placed just below the extrusion head 5.
[0025] Among them, a storage groove 20 is opened in the center of the lower surface of the turntable 9, and a square rod 21 is vertically slidably installed on the inner side of the storage groove 20. The square rod 21 can slide vertically in the center of the turntable 9, but will rotate with the turntable 9. A limit bar 24 is set at the bottom of the square rod 21. The limit bar 24 exceeds the lower surface of the turntable 9. The limit bar 24 and the internal dimensions of the limit groove 8 are adapted to each other. The stability of the turntable 9 is guaranteed by the cooperation of the two. Because of the existence of the square rod 21, the limit bar 24 will rotate with the turntable 9.
[0026] Please refer to Figure 4 and Figure 5 As shown, a mounting cavity 12 is provided on the inner side of the turntable 9, a gear ring 18 is installed on the inner side of the mounting cavity 12 through a bearing, an extrusion convex point 19 is provided on the inner side of the gear ring 18, a fixing bolt 22 is provided on the upper surface of the square rod 21, the fixing bolt 22 passes through the gear ring 18, an oblique track groove 23 is provided on the surface of the fixing bolt 22, and the extrusion convex point 19 is placed on the inner side of the oblique track groove 23. When the gear ring 18 rotates, the position of the extrusion convex point 19 will also rotate accordingly, and the fixing bolt 22 cannot rotate due to the existence of the square rod 21. When the extrusion convex point 19 rotates, the fixing bolt 22 can be moved upward by squeezing the oblique track groove 23, thereby driving the limiting strip 24 below to move upward.
[0027] Among them, gear rods 17 are symmetrically and slidably installed on both sides of the installation cavity 12, and the gear ring 18 is respectively meshed with the two gear rods 17. Installation holes 13 are opened on the surfaces of both sides of the turntable 9, and the installation holes 13 correspond to the positions of the gear rods 17. A pressing head 14 slides through the inner side of the installation hole 13, and a connecting rod 16 is arranged on the inner side of the pressing head 14. The connecting rod 16 passes through the installation hole 13, and one end of the connecting rod 16 away from the pressing head 14 is fixed to the end of the gear rod 17. A spring 15 is sleeved on the surface of the connecting rod 16, and the spring 15 is placed on the inner side of the installation hole 13. One end of the spring 15 contacts the end surface of the pressing head 14. The springs 15 on both sides can ensure that the pressing head 14 always has an outward force, and then ensure the stability of the angle of the gear ring 18 when not subject to external force.
[0028] Working principle: Due to the presence of the springs 15 on both sides, the two pressing heads 14 have outward forces respectively, and then the gear rod 17 can be pulled outward at the same time to maintain the rotation angle of the gear ring 18. At this time, the fixing bolt 22 can be placed at the bottom of the stroke by squeezing the protrusion 19 and the oblique track groove 23. At this time, the limit bar 24 and the limit groove 8 cooperate to maintain the stability of the angle. The staff loads the molding die 11 from the front side, places the magnetic core powder on the inside of the molding die 11, and then pushes the pressing head 14 from one side, which can drive the internal gear rod 17 to slide and then drive the gear ring 18 to rotate. During the rotation process, the protrusion is squeezed 19 squeezes the inclined track groove 23 to move the fixing bolt 22 upward, and then pulls the limit bar 24 upward and no longer cooperates with the limit slot 8. At this time, the turntable 9 is rotated, and the pressure on the pressing head 14 is released after rotating a certain angle. Due to the misalignment of the limit bar 24 and the limit slot 8, the limit bar 24 always has a downward force. When the rotation reaches 180°, the limit bar 24 cooperates with the limit slot 8 again to achieve limitation and remain fixed. At this time, the extrusion head 5 can be controlled by the pressing cylinder 4 to move down and cooperate with the forming mold 11 on the rear side to perform pressing and forming work, and the other forming mold 11 is rotated to the front to facilitate loading and unloading operations.
[0029] The above is only a preferred specific implementation of the utility model; however, the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and improved ideas of the utility model within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model.
