During the drawing process, the copper sheet is continuously stretched in the length direction. To prevent the copper sheet from shrinking rapidly in the width direction and causing uneven thickness during the drawing process, the tension of the copper sheet should not be too large. The traction force is controlled at 200N-350N, and the speed of the copper sheet drawing is controlled at 150mm / s-200mm / s, which is relatively inefficient. Utility Model Content

[0004] The utility model discloses an extension damping device, comprising two parallel tensioning wheels, a roller, and a fixed seat. The roller is located between the two tensioning wheels, and the roller can rotate along its own axis. The fixed seat is equipped with a rotating block, which is inserted into the fixed seat. A side plate is installed on the upper end of the rotating block, and the roller is installed on the side plate. The rotating block can actively drive the roller to rotate along the axis of the rotating block along its own axis. A gear is installed at the bottom of the rotating block, and the gear is meshed with a rack. One end of the rack in the length direction abuts against the output end of the driving member, and the other end of the rack in the length direction abuts against a slider.

[0021] The following will clearly and completely describe the technical solutions in this embodiment with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] like Figure 1As shown, an extension damping device includes two axially parallel tensioning pulleys 2 and a reel 1. The reel 1 is located above the corresponding tensioning pulley 2. A copper sheet 3 is wound around the reel 1. The copper sheet 3 is in the form of a long sheet. The copper sheet 3 extends upward from the left reel 1, around the bottom of the left tensioning pulley 2, and then extends rightward to the bottom of the right tensioning pulley 2 and upward to the right reel 1. The copper sheet 3 is pulled out from one reel 1 and rewound by the other reel 1. During the rewinding process, the copper sheet 3 is stretched and thinned. After one rewinding is completed, the pulling direction of the copper sheet 3 is changed. The copper sheet 3 is pulled back and forth multiple times to form its final shape.

[0023] like Figure 1 As shown, the extension damping device further includes a fixing seat 4, which is located below the copper sheet 3 between the two tensioning wheels 2. Figure 1 、 Figure 2 As shown, the fixing seat 4 includes a bottom plate 41 at the bottom, and the bottom plate 41 is equipped with a rotating block 5 through a bearing 52. The rotating block 5 is inserted into the bottom plate 41 and can rotate along its own axis. Figure 3 A side plate 53 is installed on the upper end of the rotating block 5, and a roller 54 is installed on the side plate 53. The roller 54 is located between the two side plates 53. The shaft 55 passes through the side plate 53 and the roller 54. The roller 54 can rotate along its own axis. The top of the roller 54 is higher than the top of the fixed seat 4. The upper end of the roller 54 abuts the copper sheet 3. The roller 54 is located between the two tensioning wheels 2.

[0024] The rotating block 5 can actively drive the roller 54 to rotate along the axis of the rotating block 5, combined with the Figure 3 、 Figure 4 、 Figure 5 The angle between the radial direction of the roller 54 and the moving direction of the copper sheet 3 is α, α is the angle between the radial direction of the roller 54 and the moving direction of the copper sheet 3, and α is set at 130° to 140° to ensure that the copper sheet 3 can drive the roller 54 to rotate along its own axis when it moves. Figure 3 In the figure, the copper sheet 3 moves along the P direction, and the radial line of the roller 54 gradually tilts upward outward from the center of the copper sheet 3. The movement of the copper sheet 3 drives the roller 54 to rotate along its own axis. The roller 54 generates a force in the s direction on the copper sheet 3. The force in the s direction is decomposed to form a force in the t direction outward from the center of the copper sheet 3, so that the roller 54 generates a force in the outward direction from the center of the copper sheet 3 on the copper sheet 3, reducing the phenomenon that the copper sheet 3 shrinks rapidly in the width direction when it is pulled in the length direction, thereby improving the consistency of the thickness of the copper sheet 3 when it is pulled, and then improving the forming quality. Similarly, if Figure 5 As shown, when the copper sheet 3 is pulled in a different direction (ie, direction Q in the figure), the roller 54 is rotated so that the roller 54 also generates an outward force along the center of the copper sheet 3 on the copper sheet 3 .

[0025] like Figure 1As shown, in order to ensure sufficient contact force between the roller 54 and the copper sheet 3, the top of the roller 54 is arranged higher than the bottom of the tensioning wheel 2.

[0026] like Figure 1 、 Figure 2 As shown, a fixing plate 42 is installed at the bottom of the fixing seat 4, a slide rail is installed at the bottom of the fixing plate 42, a slide plate 61 is installed on the slide rail, and the slide plate 61 can move left and right. A rack 6 is installed at the lower end of the slide plate 61. Figure 3 As shown, a gear 51 is installed at the bottom of the rotating block 5, and the gear 51 is engaged with the rack 6. When the rack 6 moves, it drives the gear 51 to rotate so that the roller 54 rotates. Figure 4 、 Figure 5 The left and right rows of rollers 54 are controlled by two racks 6 respectively.

[0027] like Figure 1 、 Figure 2 As shown, the right end of the rack 6 abuts against the output end of the driving member 7, which is a cylinder. The driving member 7 drives the rack 6 to move. The left end of the rack 6 abuts against the slider 82. The slider 82 is slidably connected and installed with the extension seat 8. The slider 82 is inserted into the extension seat 8. A spring 81 is installed in the extension seat 8. One end of the spring 81 abuts against the inner wall of the extension seat 8, and the other end of the spring 81 abuts against the slider 82. Figure 4 、 Figure 5 Under the cooperation of the driving member 7 and the slider 82, the two positions of the roller 54 correspond to the extended and retracted states of the driving member 7, so as to realize the rotation of the roller 54 along the axis of the rotating block 5.

[0028] The above description is merely a preferred embodiment of the present invention. The scope of protection of the present invention is not limited to the above embodiment. All technical solutions based on the concept of the present invention are within the scope of protection of the present invention. It should be noted that for those skilled in the art, certain improvements and modifications that do not depart from the principles of the present invention should also be considered within the scope of protection of the present invention.
