Technical Field

[0001] The invention relates to the technical field of copper strip processing, and in particular to a copper strip cutting and forming device and method. Background Art

[0002] The fuse wire of a fuse in the prior art is processed from a copper strip. Specifically, the copper strip is first cut into copper sheets, which are then tinned and bent to finally form the fuse wire.

[0048] In this embodiment, Fig.13 As shown, the bending mechanism 7 includes an upper die seat 71, a lower die seat 72, an upper bending cylinder 73, a lower bending cylinder 74, a bending rod assembly, and a fifth bracket 75 arranged on the frame 1. The upper bending cylinder 73 is arranged on the fifth bracket 75, and its piston rod is downward and connected to the upper die seat 71. The lower die seat 21 is located directly below the upper die seat 71. The two are matched to bend the middle part of the copper single sheet.

[0049] In this embodiment, the present invention further comprises a material receiving box 8, which is located at the cutting mechanism 3, and the formed copper single sheet 20' (such as Fig.14 As shown) the other clamping rotating mechanism 6 pushes the material into the receiving box 8 when feeding the material next time. Fig.14As shown, the material receiving box 8 is located at the front side of the lower die base 72 , and an inclined material guiding groove 81 is provided at the top of one end of the material receiving box 8 close to the lower die base 72 .

[0050] In this embodiment, the present invention further comprises a controller 9, which cooperates with the feeding mechanism 2, the cutting mechanism 3, the tinning mechanism 5, the bending mechanism 7, and the two clamping and rotating mechanisms 4 and 6 to control the coordinated actions of these mechanisms. The controller 9 can be a PLC controller.

[0051] A copper strip cutting and forming device of the present invention has the following working process:

[0052] The first motor 22 is started, driving the turntable 21 and the copper strip roll thereon to rotate, and the end of the copper strip passes through the gap between the feeding roller 27 and the clamping roller 28. The feeding roller 27 is driven by the second motor 26, and cooperates with the clamping roller 28 to transport the end of the copper strip to the knife seat 31 of the cutting mechanism 3. Then, the cutting cylinder 32 is activated, driving the first movable plate 34 to move downward, so that the punching knife 37, the two cutting knives 36, and the three positioning needles 38 move downward at the same time, thereby cutting the end of the copper strip into a copper single piece 20 with a preset shape and a tin point hole in the middle. As the first movable plate 34 moves downward, the pusher 212 also pushes one end of the swing rod 213 downward, so that the other end of the swing rod 213 lifts the movable bracket 210, so that the clamping roller 28 releases the copper strip 10, and prevents the clamping roller 28 from pressing the copper strip all the time and causing the copper strip to deviate. After cutting is completed, the cutting cylinder 32 drives the first movable plate 34 and the punch 37, cutter 36 and positioning pin 38 thereon to reset upward, the rocker 213 releases the movable bracket 210, and the movable bracket 210 relies on the elastic member to drive the clamping roller 28 to reset downward to a state where the copper strip is pressed again. At the same time, one of the clamping and rotating mechanisms 4 starts to move: the stroke cylinder 43 pushes the pneumatic finger 44 to the knife seat 31, and the two clamping blocks 45 on the pneumatic finger 44 clamp the middle of the copper single piece. Then, the rotating cylinder 41 drives the stroke cylinder 43 to rotate 180°, so that the pneumatic finger 44 faces the other clamping and rotating mechanism 6. After that, another clamping and rotating mechanism 6 starts to work: the two U-shaped clamps 65 on the pneumatic fingers 64 clamp the two ends of the copper sheet, and the copper sheet is transported to the tinning station (i.e., placed on the top of the support rod 55) under the push of the stroke cylinder 63. Then, the tinning cylinder 51 is activated to drive the electric soldering iron 52 to move downward, and the electric soldering iron 52 automatically tins the tinning hole in the middle of the copper sheet. After the tinning is completed, the rotating cylinder 61 of the other clamping and rotating mechanism 6 is started, driving the stroke cylinder 63 to rotate 180°, so that the pneumatic fingers 64 transport the copper sheet with tinning to the lower die seat 72. After the copper sheet reaches the lower die seat 72, the other clamping and rotating mechanism 6 is reset and the above action is repeated. At the same time, the upper bending cylinder 73 drives the upper die seat 71 to move downward, and the upper die seat 71 cooperates with the lower die seat 72 to bend the middle of the copper sheet into a W shape. Next, the lower bending cylinder 74 moves, driving the two bending rods 76 and the two push rods 77 to move upward at the same time, so that the two push rods 77 support the inner parts of the two ends of the copper sheet, and the two bending rods 76 cooperate with the upper die seat 71 to bend the two ends of the copper sheet upward to 90°. When the other clamping and rotating mechanism 6 transports the copper sheet that has been tinned to the bending mechanism 7 again, the other clamping and rotating mechanism 6 pushes the formed copper sheet on the lower die seat 72 into the receiving box 8 at the same time. By repeating the cycle in this way, the copper strip can be processed into many copper sheet products. The upper bending cylinder 73 and the lower bending cylinder 74 act successively, so that the middle part of the copper sheet has space for deformation when bending to avoid breakage.

[0053] The copper strip cutting and forming device of the present invention adopts the feeding mechanism 2, two clamping and rotating mechanisms 4, 6 to cooperate with the cutting mechanism 3, the tinning mechanism 5, and the bending mechanism 7 to form a complete set of copper strip cutting and forming device, which can automatically complete the feeding, cutting, tinning, and bending processes of the copper strip, thereby greatly improving the production efficiency and greatly reducing the labor intensity.

[0054] A copper strip cutting and forming method of the present invention adopts a copper strip cutting and forming device of the present invention, comprising the following steps:

[0055] 1) The feeding mechanism 2 conveys the copper strip to the cutting mechanism 3;

[0056] 2) The cutting mechanism 3 cuts and punches the end of the copper strip to obtain a copper sheet with a preset shape and a tin point hole, and during the cutting process, the roller of the feeding mechanism 2 presses the feeding assembly to release the copper strip;

[0057] 3) One of the clamping and rotating mechanisms 4 clamps the middle of the copper sheet from the cutting mechanism 3 and transfers it to another clamping and rotating mechanism 6, and the other clamping and rotating mechanism 6 clamps both ends of the copper sheet;

[0058] 4) Another clamping and rotating mechanism 6 transports the copper sheet to the tinning mechanism 5 for tinning;

[0059] 5) Another clamping and rotating mechanism 6 transports the copper sheet that has been tinned to the bending mechanism 7 for bending and forming;

[0060] 6) The copper sheet formed on the bending mechanism 7 is pushed off by another clamping and rotating mechanism 6 when feeding next time.

[0061] The detailed process of the copper strip cutting and forming method of the present invention is as described above and will not be repeated here.

[0062] The above embodiments are only used to further illustrate a copper strip cutting and forming device and method of the present invention, but the present invention is not limited to the embodiments.
