Detailed Implementation

[0029] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.

[0030] like Figures 1-8 As shown, a stamping device for iron core processing includes a base 1, a lower die 2 fixedly installed on the upper surface of the base 1, a plurality of push rods 3 fixedly installed on the upper surface of the base 1, a top plate 4 fixedly installed on the upper surface of each push rod 3, a hydraulic cylinder 5 fixedly installed on the upper surface of the top plate 4, the output end of the hydraulic cylinder 5 passes through the top plate 4 and is fixedly installed with an upper die 6, and the upper dies 6 are slidably arranged on one side of the rod body of each push rod 3.

[0031] A material receiving component 7 for receiving materials is provided on one side of the base 1.

[0032] The receiving assembly 7 includes a support base 701, which is fixedly installed on one side of the base 1. A reciprocating screw 702 is rotatably installed between the two sides of the inner wall of the support base 701. A movable plate 703 is slidably arranged inside the support base 701. The movable plate 703 is threaded on one side of the reciprocating screw 702. A movable frame 704 is fixedly installed on the upper surface of the movable plate 703. Two uprights 705 are fixedly installed on the upper surface of the movable frame 704. Guide plates 706 are fixedly installed on the upper ends of the two uprights 705.

[0033] A motor 707 is fixedly installed on one side of the support base 701, and one end of the reciprocating lead screw 702 passes through the support base 701 and is fixedly connected to the output shaft end of the motor 707.

[0034] The worker places the material plate between the upper mold 6 and the lower mold 2. Then, the worker starts the hydraulic cylinder 5, which drives the upper mold 6 to move. The moving upper mold 6, in cooperation with the lower mold 2, allows the material plate to be stamped and formed. When the upper mold 6 moves to its original position, the worker starts the motor 707, which drives the reciprocating screw 702 to rotate. The rotating reciprocating screw 702 drives the moving frame 704 to move by screwing in the thread. When the upper mold 6 rises, the guide plate 706 can move between the upper mold 6 and the lower mold 2, so that the formed parts falling from the upper mold 6 can fall into the guide plate 706. Then, when the upper mold 6 falls, the reciprocating screw 702 continues to rotate, so that the guide plate 706 moves to its original position, preventing the formed parts from accumulating and preventing obstruction of the normal operation of the lower mold 2.

[0035] In another embodiment of this utility model, two uprights 8 are fixedly installed on both sides of the movable frame 704, and an mounting ring 9 is fixedly installed on the upper end of the adjacent uprights 8. A filter cylinder 10 is rotatably installed inside the two mounting rings 9.

[0036] By setting up a filter cylinder 10, the molded part moving along one of the guide plates 706 can enter the filter cylinder 10, so that the filter holes on the surface of the filter cylinder 10 can filter the debris on the surface of the molded part, preventing the debris from following the molded part into the storage position and requiring the staff to manually remove the debris.

[0037] In another embodiment of the present invention, one end of the reciprocating screw 702 passes through the support base 701 and is fitted with a first pulley 11;

[0038] Two support blocks 12 are fixedly installed on one side of the support base 701. A crossbar 13 is rotatably installed between the support blocks 12. One end of the crossbar 13 passes through the corresponding support block 12 and is fitted with a second pulley 1301. The second pulley 1301 and the surface of the first pulley 11 are fitted with a first belt 1302. A long gear 14 is fitted on one side of the crossbar 13.

[0039] The movable frame 704 has mounting brackets 15 fixedly installed on both sides. A connecting block 16 is fixedly installed on one side of the mounting bracket 15. A connecting shaft 1601 is rotatably installed through one side of the connecting block 16. A short gear 17 is sleeved on one side of the shaft of the connecting shaft 1601. The short gear 17 meshes with the long gear 14.

[0040] A third pulley 18 is sleeved on the other side of the shaft of the connecting shaft 1601. A fixing block 19 is fixedly installed on one side of the mounting bracket 15. A horizontal shaft 20 is rotatably installed on one side of the fixing block 19. A fourth pulley 21 is sleeved on one side of the shaft of the horizontal shaft 20. A second belt 22 is sleeved on the surface of the third pulley 18 and the fourth pulley 21.

[0041] A fifth pulley 23 is sleeved on the other side of the horizontal shaft 20. An installation shaft 24 is rotatably installed between the two sides of the inner wall of the mounting bracket 15. A rotating wheel 25 is sleeved on the shaft of the installation shaft 24. Several first push plates 26 are fixedly installed on the surface of the rotating wheel 25. Several second push plates 27 are fixedly installed on the body of the filter cylinder 10.

[0042] One end of the mounting shaft 24 passes through the mounting bracket 15 and is fitted with a sixth pulley 28. The surface of the sixth pulley 28 and the fifth pulley 23 are fitted with a third belt 29.

[0043] When the reciprocating screw 702 rotates, it drives the first pulley 11 to rotate. Under the transmission action of the first belt 1302, the second pulley 1301 drives the crossbar 13 to rotate. Under the meshing action of the long gear 14 and the short gear 17, the connecting shaft 1601 drives the third pulley 18 to rotate. Under the transmission action of the second belt 22, the fourth pulley 21 drives the horizontal shaft 20 and the fifth pulley 23 to rotate. Under the action of the third belt 29, the sixth pulley 28 drives the mounting shaft 24 and the rotating wheel 25 to rotate. Under the pushing action of the first push plate 26 on the second push plate 27, the second push plate 27 can drive the filter cylinder 10 to rotate, causing the molded parts inside the filter cylinder 10 to tumble, so that the debris falls more fully from the surface of the molded parts, improving the filtration effect.

[0044] In another embodiment of this utility model, two rollers 30 are rotatably mounted on both sides of the movable frame 704.

[0045] By setting rollers 30, the rollers 30 can be used to shape the moving frame 704 without affecting its movement, thus preventing the reciprocating screw 702 from bending due to excessive stress.

[0046] Working principle of a stamping device for iron core processing:

[0047] In use, the operator places the material plate between the upper mold 6 and the lower mold 2. Then, the operator starts the hydraulic cylinder 5, which drives the upper mold 6 to move. The moving upper mold 6, in cooperation with the lower mold 2, allows the material plate to be stamped and formed. When the upper mold 6 moves to its original position, the operator starts the motor 707, which drives the reciprocating screw 702 to rotate through its output shaft. The rotating reciprocating screw 702 drives the moving frame 704 to move through the threaded advance. When the upper mold 6 rises, the guide plate 706 can move between the upper mold 6 and the lower mold 2, so that the formed parts falling from the upper mold 6 can fall into the guide plate 706. Then, when the upper mold 6 descends, the reciprocating screw 702 continues to rotate, so that the guide plate 706 moves to its original position, preventing the formed parts from accumulating and preventing obstruction of the normal operation of the lower mold 2.

[0048] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating this utility model, and are not intended to limit the implementation of this utility model. For those skilled in the art, other variations or modifications can be made based on the above description. It is impossible to exhaustively list all the implementation methods here. Any obvious variations or modifications derived from the technical solutions of this utility model are still within the protection scope of this utility model.
