[0012] The utility model provides a synchronous unloading device at the front of the cutting table. When the copper strip cutting action is performed, the cutter moves downwards to perform the cutting action and cooperates with the cutting groove to cut the copper strip into pieces, thereby realizing the copper strip cutting. The separated copper strip slices stay on the inner side of the unloading channel, and then the cutter continues to move downwards along the inner side of the cutting groove, so that the height of the pressure wheel is lowered and fits on the top of the unloading bin. Then the knife seat applies downward pressure to the pressure wheel through the connecting frame, so that the pressure wheel pushes the unloading bin to flip downward, so that the unloading channel is tilted and the internal copper strip slices are discharged downward, thereby realizing the unloading operation of the copper strip slices. The copper strip slices can be quickly unloaded after the cutter completes cutting, so that the cutter can quickly enter the next round of cutting process, greatly shortening the time of cutting equipment downtime waiting for unloading, and effectively improving the cutting work efficiency.

DETAILED DESCRIPTION

[0020] In order to further explain the technical solution of the present invention, specific embodiments are described in detail below.

[0021] See also Figure 1 The utility model provides a continuous cold extrusion cutting device for copper strips, comprising a cutting table 1, a cutting groove 2, a cutting knife 3, a knife holder 4 and a synchronous unloading device 5. A cutting groove 2 is opened on the top surface of the cutting table 1, and a cutting knife 3 is provided above the cutting table 1. The cutting knife 3 is located directly above the cutting groove 2. The cutting knife 3 is bolted to the bottom of the knife holder 4, and a synchronous unloading device 5 is provided at the front of the cutting table 1.

[0022] See also Figure 2-5 The utility model provides a continuous cold extrusion cutting device for copper strips. The synchronous unloading device 5 includes a unloading bin 51, a torsion spring hinge 52, a unloading channel 53, a connecting frame 54 and a pressure wheel 55. A unloading bin 51 is provided at the front of the cutting table 1. A torsion spring hinge 52 is installed at the rear end of the bottom surface of the unloading bin 51. The torsion spring hinge 52 is connected to the front side wall of the cutting table 1. The unloading bin 51 is hinged to the cutting table 1 through the torsion spring hinge 52. The torsion spring hinge 52 can provide an elastic force for the unloading bin 51 to flip upward and reset. A connecting frame 54 is screwed on the front of the knife holder 4. A pressure wheel 55 is rotatably installed at the bottom end of the connecting frame 54. The pressure wheel 55 is located above the unloading bin 51.

[0023] It is further explained that the maximum turning angle range of the torsion spring hinge 52 is not less than 45 degrees, and the torsion spring hinge 52 can provide a sufficient turning angle for the unloading bin 51 to ensure that the copper strip slices can be unloaded smoothly.

[0024] It is further explained that the bottom surface of the unloading channel 53 is coated with a Teflon coating 531. The Teflon coating 531 has good lubricity and can improve the smoothness of the bottom surface of the unloading channel 53, which helps to smoothly unload the copper strip slices.

[0025] It is further explained that the height difference between the cutter 3 and the cutting groove 2 is smaller than the height difference between the pressure wheel 55 and the unloading bin 51, and the difference between the two height differences is at least 2 cm. Before the cutter 3 enters the inner side of the cutting groove 2, the pressure wheel 55 cannot contact the unloading bin 51, thereby preventing the unloading bin 51 from flipping down too early and causing the copper strip to bend and be damaged.

[0026] To further illustrate, a docking bridge 56 is integrally provided at the rear of the discharge channel 53 , and a docking groove 57 is provided at the front edge of the top surface of the cutting table 1 . The docking bridge 56 can be flipped and snapped into the inner side of the docking groove 57 to improve the connectivity between the discharge channel 53 and the cutting table 1 .

[0027] To further illustrate, when the docking bridge 56 and the docking groove 57 are in the connected state, the bottom surface of the discharge channel 53 is aligned with the height of the top surface of the cutting table 1 , and the copper strip can be smoothly guided into the inner side of the discharge channel 53 along the cutting table 1 .

[0028] It is further explained that the height of the discharge channel 53 is 1-2.5 cm to better adapt to copper strips of different thickness specifications.

[0029] Here’s how it works:

[0030] First, install the knife holder 4 and the cutting mechanism of the equipment. Before cutting the copper strip, guide the copper strip along the cutting table 1 to the cutting groove 2. During this process, the part of the copper strip to be cut will move and stop inside the feed and unloading channel 53.

[0031] Second, when the copper strip is cut, the cutter 3 moves downward to perform the cutting action and cooperates with the cutting groove 2 to cut the copper strip into pieces, thereby realizing the cutting of the copper strip. The separated copper strip slices stay on the inner side of the unloading channel 53, and then the cutter 3 continues to move downward along the inner side of the cutting groove 2, so that the pressure wheel 55 is lowered and fits on the top of the unloading bin 51, and then the knife holder 4 applies downward pressure to the pressure wheel 55 through the connecting frame 54, so that the pressure wheel 55 pushes the unloading bin 51 to flip downward, so that the unloading channel 53 is tilted to unload the internal copper strip slices downward, thereby realizing the unloading operation of the copper strip slices, and the copper strip slices can be quickly unloaded after the cutter 3 completes the cutting, so that the cutter 3 can quickly enter the next round of cutting process, which greatly shortens the time of the cutting equipment waiting for unloading and effectively improves the cutting work efficiency.

[0032] Third, after the cutter 3 moves up and resets, the discharge bin 51 will also automatically move up and reset under the torque force of the torsion spring hinge 52, causing the docking bridge 56 to flip and snap into the inner side of the docking groove 57, restoring the connection between the cutting table 1 and the discharge channel 53, and the next round of cutting process can be resumed.

[0033] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art will be able to modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein with equivalents. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
