[0022] In order to make the objectives, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with specific embodiments.

[0024] like Figure 1-3 As shown, a continuous rolling machine for copper alloy flat wire comprises a first conveyor frame 1; a second conveyor frame 2, which is aligned with the first conveyor frame 1 and arranged in a line; a rolling track 3, which is arranged between the first conveyor frame 1 and the second conveyor frame 2 and is arranged perpendicular to the first conveyor frame 1; a rolling car 4, which is arranged on the rolling track 3, moves and stops along the rolling track 3; rolling rollers, including a first rolling roller 5, which is arranged on one end of the first conveyor frame 1 facing the second conveyor frame 2; a second rolling roller 6, which is arranged on the rolling car 4, and cooperates with the first rolling roller 5 to roll the copper alloy flat wire; the copper alloy flat wire reciprocates back and forth on the first conveyor frame 1 and the second conveyor frame 2 through the gap between the first rolling roller 5 and the second rolling roller 6 of the rolling rollers, thereby realizing the rolling of the copper alloy flat wire.
[0025] The first conveyor frame 1 and the second conveyor frame 2 move back and forth with the copper alloy, and each movement passes through the gap between the first rolling roller 5 and the second rolling roller 6, thereby rolling the copper alloy. After several rollings, the gap between the first rolling roller 5 and the second rolling roller 6 is reduced, and the copper alloy is continuously rolled. After multiple adjustments, the copper alloy has the required thickness.
[0026] In order to maintain controllable adjustment, the axis of the first rolling roller 5 and the axis of the second rolling roller 6 are in the same vertical plane, so as to avoid the copper alloy being passively bent after rolling due to not being in the same vertical plane.
[0027] In order to quickly adjust the gap thickness between the first rolling roller 5 and the second rolling roller 6, the second rolling roller 6 is in the shape of a stepped shaft, and each step of the stepped shaft is cylindrical. The different steps of the stepped shaft of the second rolling roller 6 cooperate with the first rolling roller 5 to roll the copper alloy flat wires of different stages by moving the rolling car 4. The adjustment speed and accuracy are greatly improved by moving the rolling car 4 for rapid adjustment.
[0028] Furthermore, in order to control the movement law of the rolling car 4, the stage of the stepped shaft of the second rolling roller 6 is divided into four stages from one end of the second rolling roller 6 to the other end of the second rolling roller 6, namely the first stage, the second stage, the third stage and the fourth stage; from one end to the other end of the second rolling roller 6, the diameters of the four stages increase successively, the diameter of the first stage is the smallest, and the diameter of the fourth stage is the largest.
[0029] Furthermore, in order to control the movement amplitude of the rolling car 4, the length of each of the four stages of the second rolling roller 6 is equal and greater than the length of the first rolling roller 5. In this way, each time the rolling car 4 moves the length of one stage, different stages can be matched with the first rolling roller 5, thereby controlling the size of the gap between the first rolling roller 5 and the second rolling roller 6.
[0030] In order to make the adjustment range of the gap controllable, the diameter difference between adjacent stages from one end to the other end of the second rolling roller 6 is equal, and the diameter difference between adjacent stages is one millimeter.
[0031] The rolling car 4 includes a car body, wheels 43 arranged on the car body, hub motors 44 arranged on the wheels, and a counterweight 45 arranged above the car body; the counterweight 45 suppresses the rolling car 4 to prevent the rolling car 4 from jumping up during the rolling process. The wheels 43 are arranged on the rolling track 3, and the hub motors 44 drive the wheels 43 to rotate, thereby driving the rolling car 4 to move on the rolling track 3.
[0032] In order to be able to laterally adjust the position of the second rolling roller 6, the car body includes a lower car body 41 and an upper car body 42 arranged on the upper part of the lower car body 41, the bottom of the upper car body 42 is provided with a dovetail groove 46, the upper part of the lower car body 41 is provided with a dovetail rib 47, and the dovetail rib 47 is inserted into the dovetail groove 46; the dovetail groove 46 and the dovetail rib 47 are both perpendicular to the axis of the second rolling roller 6; an L-shaped top plate 48 is provided on the side of the lower car body 41, and a first threaded hole is provided on the L-shaped top plate 48, and a threaded rod 49 is provided on the first threaded hole; a second threaded hole is provided on the side of the upper car body 42, and the threaded rod 49 is inserted into the second threaded hole, and the position of the upper car body 42 and the lower car body 41 can be adjusted by rotating the threaded rod 49. In order to be able to adjust the longitudinal height, a height adjusting device is further provided on the upper part of the upper vehicle body 42 , and the second rolling roller 6 is arranged on the height adjusting device, and the gap between the second rolling roller 6 and the first rolling roller 5 is adjusted by the height adjusting device.
[0033] The height adjustment device includes two triangular brackets 51, a stabilizing rod 52 and a hydraulic telescopic rod 53; the two triangular brackets 51 are parallel to each other, and the upper corners 511 of the two triangular brackets 51 are rotatably connected to the two ends of the second rolling roller 6 respectively; the middle corners 512 of the lower parts of the two triangular brackets 51 are rotatably connected to the upper surface of the upper car body 42 through a rotating shaft; the two ends of the stabilizing rod 52 are respectively connected to the third corners 513 of the two triangular brackets 51; the two ends of the hydraulic telescopic rod 53 are respectively connected to the stabilizing rod 52 and the upper surface of the upper car body 42 through a pin shaft; the angle of the triangular bracket 51 is changed by telescoping the hydraulic telescopic rod 53, thereby changing the height of the second rolling roller 6; and the horizontal position of the second rolling roller 6 is adjusted by rotating the threaded rod 49 to keep the axis of the first rolling roller 5 and the axis of the second rolling roller 6 in the same vertical plane, thereby ensuring that the gap between the first rolling roller 5 and the second rolling roller 6 meets the rolling requirements.
