DETAILED DESCRIPTION

[0026] Now the utility model is further described in detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the utility model in a schematic manner, and therefore only show the components related to the utility model.

[0027] See also Figure 2 , Figure 2 This is a stereogram of the best embodiment of a tin-phosphor bronze strip cutting device of the utility model. Figure 2 As shown, at least one embodiment provides a tin-phosphor bronze strip cutting device, including: an operating frame 100, a reeling assembly 200, a conveying assembly 300 and a cutting assembly 400, wherein the reeling assembly 200, the conveying assembly 300 and the cutting assembly 400 are all arranged on the operating frame 100, and a limiting structure 500 is fixed on the operating frame 100 directly below the cutting assembly 400. Specifically, the reeling assembly 200, the conveying assembly 300 and the cutting assembly 400 are arranged in sequence from the back edge to the front edge of the operating frame 100. It should be additionally supplemented that the tin-phosphor bronze strip needs to pass through the limiting structure 500 from one side to the other side.

[0028] Please continue reading Figure 2 .like Figure 2As shown, in order to prevent the cutting end face from being difficult to pull out at the center of the limiting structure 500 after cutting, a transmission assembly 300 is also provided on the operating frame 100, and the transmission assembly 300 can allow the cut copper strip end face to move forward again. Specifically, the transmission assembly 300 includes an active rotating rod 301, which is rotatably connected to the operating frame 100, and one end of the active rotating rod 301 is connected to a driving structure. The surface of the active rotating rod 301 is covered with a conveying roller 302, and the surface of the conveying roller 302 is covered with a rubber layer, and the surface of the rubber layer is provided with a convex structure, which is an integral structure with the rubber layer, mainly to increase friction and evenly convey the copper strip.

[0029] Please continue reading Figure 2 .like Figure 2 As shown, the cutting assembly 400 includes a press platform 401 and a blade 402 fixed to the bottom of the press platform 401 . Both sides of the press platform 401 are connected to the operating frame 100 through a sliding structure, and a cylinder is installed on the top of the press platform 401 .

[0030] Please continue reading Figure 2 Combined with Figure 3 to Figure 4 , Figure 3 A three-dimensional diagram of the optimal embodiment of the limiting structure of the utility model; Figure 4 Schematic diagram of the structure of the optimal embodiment of the lifting platform of the utility model. Figures 2 to 4 As shown, the limiting structure 500 includes a lifting platform 501 , a plurality of round holes 504 are formed on the lifting platform 501 , the lifting platform 501 has a front side and a back side, a limiting groove 502 is formed from the front side to the back side, and the limiting groove 502 runs through the lifting platform 501 . A cutting groove 503 is provided on the top surface of the lifting platform 501, and a knife receiving groove 506 is provided on the bottom surface. Both the cutting groove 503 and the knife receiving groove 506 are connected to the limiting groove 502. The width of the knife receiving groove 506 is smaller than the width of the cutting groove 503. The knife strip 402 is arranged directly above the knife receiving groove 506. The width of the knife receiving groove 506 is 1.5-3 times the width of the knife strip 402. In addition, the tin-phosphor bronze strip is inserted from the back side of the limiting groove 502 and exits from the front side. When the pressing platform 401 pushes the knife strip 402 downward, the knife strip 402 passes through the cutting groove 503 and falls at the position of the knife receiving groove 506. At this time, the tin-phosphor bronze strip across the cutting groove 503 will be punched and cut off. It should be additionally noted that when the knife strip 402 moves to the lowest horizontal line, the pressing platform 401 is at a certain distance from the top surface of the lifting platform 501.

[0031] Please continue reading Figure 3 And combined with 5, Figure 5 3D diagram of the optimal embodiment of the clamping part of the utility model. Figure 3 and Figure 5As shown, a clamping portion 505 is provided in the circular hole 504, and a part of the clamping portion 505 extends above the lifting platform 501. In the initial state, the bottom surface of the clamping portion 505 does not contact the bottom surface of the limiting groove 502. When the tin-phosphor bronze strip passes through the limiting groove 502, the clamping portion 505 does not contact the copper strip. During the downward pressing process of the pressing platform 401, the bottom surface will abut against the top of the clamping portion 505, and the continuous downward pressing drives the clamping portion 505 to squeeze the surface of the copper strip, so that the position of the copper strip before cutting can be fixed. It should be further explained that the clamping portion 505 includes an elastic column 5051, and the elastic column 5051 is arranged at the position of the circular hole 504, and the elastic column 5051 is fixed on the inner wall of the circular hole 504 by a spring, one end of the spring is fixedly connected to the inner wall of the circular hole 504, and the other end is fixedly connected to the elastic column 5051, so that the top of the elastic column 5051 in a non-pressed state extends out of the circular hole 504, and the bottom surface of the rubber hemisphere 5052 does not contact the copper belt. After the pressing platform 401 squeezes the elastic column 5051 and moves downward, the rubber hemisphere 5052 contacts the copper belt, and the bottom of the elastic column 5051 is provided with a rubber hemisphere 5052, and the inside of the rubber hemisphere 5052 is provided with an air storage cavity. The surface of the rubber hemisphere 5052 is provided with a plurality of exhaust holes 5053. The opening direction of the exhaust holes 5053 faces the center position of the knife groove 506, so that the metal chips generated during the stamping can be concentrated under the knife groove 506 under the blowing, so as to avoid the metal chips sticking to the surface of the copper belt and causing the knife edge to be blunt when the copper belt is pressed and cut next time.

[0032] In summary, by providing the limit groove 502, the copper strip can be kept in a certain frame during the transmission process, thereby reducing the number of work steps for adjusting the position of the copper strip before cutting; by providing the clamping portion 505, the copper strip can be fixed while being cut, thereby avoiding the deformation of the copper strip during the cutting process; by providing the exhaust hole 5053, the metal chips can be cleaned, thereby avoiding the blunting of the blade due to the presence of metal chips.

[0033] Based on the above ideal embodiments of the utility model, the relevant staff can make various changes and modifications without deviating from the technical concept of the utility model through the above description. The technical scope of the utility model is not limited to the content of the specification, and its technical scope must be determined according to the scope of the claims.
