Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] The utility model provides Figures 1 to 5 The copper alloy plate continuous extrusion forming device shown comprises:

[0029] Squeeze chamber 1;

[0030] Extrusion components for extruding copper alloys;

[0031] The extrusion assembly includes a movable frame 2 movably arranged on the top of the extrusion bin 1, two groups of first hydraulic cylinders 3 are installed on the top of the movable frame 2, the output end of the first hydraulic cylinder 3 passes through the movable frame 2 and extends downward and is fixed with an extrusion block 4, the extrusion block 4 is located in the extrusion bin 1, and a translation assembly 5 for moving the movable frame 2 is arranged on the outside of the extrusion bin 1;

[0032] A vertical bin 6 is fixed at the bottom of the extrusion bin 1. A through slot 7 communicating with the vertical bin 6 is provided at the bottom of the extrusion bin 1. A second hydraulic cylinder 8 is fixed at the bottom of the vertical bin 6. The output end of the second hydraulic cylinder 8 passes through the inner cavity of the vertical bin 6 and is fixed with a push plate 9.

[0033] It also includes movable plates 10 located on both sides of the bottom of the inner cavity of the extrusion chamber 1. The outer side of the movable plate 10 penetrates the extrusion chamber 1 and extends outward. The bottom of the extrusion chamber 1 is provided with a push assembly 11 for moving the movable plate 10.

[0034] By driving the movable frame 2 to translate on the top of the extrusion bin 1 through the translation assembly 5, it is convenient for the first hydraulic cylinder 3 to drive the extrusion block 4 to continuously extrude the copper alloy, and then the push assembly 11 drives the movable plate 10 to move toward each other. The movable plates 10 are closed together to support the copper alloy. The separation of the movable plates 10 facilitates the copper alloy to enter the vertical bin 6 through the through groove 7 for folding processing. The second hydraulic cylinder 8 can drive the push plate 9 to move the folded copper alloy out of the vertical bin 6 and into the extrusion bin 1 for continued extrusion processing. Not only can continuous and uninterrupted processing be achieved, but the extrusion method can also be controlled to ensure the final extrusion effect.

[0035] The translation assembly 5 includes support plates 51 fixed on both sides of the back side of the extrusion bin 1, and the opposite sides of the support plates 51 are rotatably connected with a screw rod 52 through a bearing. A threaded sleeve 53 is fixedly embedded at the lower end of the movable frame 2, and the screw rod 52 threadably penetrates the threaded sleeve 53. A driving motor 54 is fixed to the outer side of a group of support plates 51, and the output shaft of the driving motor 54 is fixedly connected to one end of the screw rod 52. The screw rod 52 is driven to rotate by the driving motor 54, and the threaded sleeve 53 is conveniently used to rotate and translate on the outer side of the screw rod 52 to move the movable frame 2, and the extrusion block 4 is driven to move in the extrusion bin 1 through the movable frame 2.

[0036] The push assembly 11 includes a third hydraulic cylinder 111 fixed on both sides of the bottom of the extrusion bin 1. A connecting block 112 is fixed to the output end of the third hydraulic cylinder 111. The connecting block 112 is fixed to the bottom of the movable plate 10. Both sides of the bottom of the extrusion bin 1 are provided with guide grooves 113 for guiding the connecting block 112. The third hydraulic cylinder 111 drives the connecting block 112 to push the movable plate 10 horizontally, adjust the position between the two groups of movable plates 10, and prepare for the copper alloy to enter the vertical bin 6 and fold.

[0037] A limiting frame 12 is fixed at the front end of the top of the extrusion bin 1, and the front end of the movable frame 2 extends to the inner side of the limiting frame 12 and fits against the inner wall of the limiting frame 12. Through the cooperation of the limiting frame 12, the movable frame 2 is limited to ensure that the movable frame 2 remains stable and prevents the movable frame 2 from shaking, which would cause the output shaft of the first hydraulic bin to bend and break.

[0038] A limiting groove 13 is provided at the bottom of the inner cavity of the extrusion bin 1, and a limiting bar 14 slidably connected to the inner cavity of the limiting groove 13 is fixed at the bottom of the movable plate 10. By sliding the limiting bar 14 in the limiting groove 13, it is ensured that the movable plate 10 always moves in contact with the bottom of the inner cavity of the extrusion bin 1.

[0039] Limit rods 15 are fixed at both the front and rear ends of the bottom of the push plate 9. The end of the limit rod 15 away from the push plate 9 passes through the vertical bin 6 and extends outward. Through the setting of the limit rod 15, it is convenient to limit the push plate 9 to prevent the front and rear ends of the push plate 9 from not being on the same horizontal plane, causing the push plate 9 to be stuck in the vertical bin 6.

[0040] The size of the through groove 7 is the same as the top view size of the inner cavity of the vertical bin 6, and the width of the extrusion block 4 is smaller than the width of the through groove 7. By limiting the size of the extrusion block 4 and the through groove 7, it is ensured that the extrusion block 4 can carry the copper alloy downward and penetrate into the vertical bin 6.

[0041] It also includes a controller 16 fixed on the outside of the extrusion bin 1, and the controller 16 is electrically connected to the first hydraulic cylinder 3, the second hydraulic cylinder 8, the third hydraulic cylinder 111 and the drive motor 54 respectively. Through the controller 16, the first hydraulic cylinder 3, the second hydraulic cylinder 8, the third hydraulic cylinder 111 and the drive motor 54 can be controlled to realize automated operation.

[0042] During specific use, the copper alloy is placed in the extrusion bin 1, and then the first hydraulic cylinder 3 is started through the controller 16. The first hydraulic cylinder 3 drives the extrusion block 4 to extrude the copper alloy in the extrusion bin 1, and then the driving motor 54 drives the screw 52 to rotate, and drives the movable frame 2 to translate on the outside of the extrusion bin 1 through the threaded sleeve 53, so that the extrusion block 4 flattens the copper alloy inside the extrusion bin 1, so that the copper alloy is spread flat on the bottom of the inner cavity of the extrusion bin 1, and then the third hydraulic cylinder 111 drives the movable plate 10 to move to both sides through the connecting block 112, and the extrusion bin 1 is connected with the vertical bin 6 by the through groove 7, and then the first hydraulic cylinder 3 drives the extrusion block 4 to extrude the copper alloy from the through groove 7 into the vertical bin 6, and then drives the movable plate 10 in the reverse direction to extrude the copper alloy, so that the copper alloy is folded, and finally the second hydraulic cylinder 8 pushes the copper alloy upward from the vertical bin 6 through the push plate 9, moves it back into the extrusion bin 1, and extrudes it again, so as to achieve multiple uninterrupted extrusion molding operations.

[0043] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
