Description

Technical Field

[0001] This utility model belongs to the field of copper busbar stamping technology, and specifically relates to a copper busbar production device. Background Technology

[0002] A copper busbar is a high-current conductive product, also known as a copper busbar, copper busbar, or copper busbar. Copper busbars are mostly made by welding together a certain number of thin copper sheets.

[0003] In existing technology, a stamping machine (stamping die) cuts copper strip into single-layer copper sheets, with a large number of copper sheets scattered randomly on the worktable. The copper sheets are then manually arranged and counted, and finally, the arranged copper sheets are welded. The following problems often arise:

[0004] 1. Manually collecting copper sheets, arranging and counting them is labor-intensive and prone to discrepancies in the number of copper sheets in the copper bars;

[0005] 2. The surface of the copper sheets is smooth. When stacking copper sheets, multiple copper sheets are easy to become loose and it is difficult to align them. Utility Model Content

[0006] To address the problems and shortcomings of the existing technology, this utility model provides a copper busbar production device. By punching protrusions onto copper sheets and using a second punch to press adjacent copper sheets together, the manual stacking step is eliminated, improving the production efficiency of copper busbars. A counter is set on the first punch, and when a set number of punches is reached, holes are punched in the copper sheets to ensure that each copper busbar contains a consistent number of copper sheets.

[0007] This utility model is achieved through the following technical solution:

[0008] A copper busbar production apparatus includes a lower die base and an upper die punch. The lower die base includes an integrally formed first lower die and a second lower die. The top of the first lower die has a first blanking groove. Inside the first lower die are a stamping rod and a stamping machine that drives the stamping rod to move vertically. The stamping machine has a counter connected to the stamping machine data to count the number of stamping operations. A floating plate is provided in the first blanking groove to facilitate the ejection of copper sheets located in the first blanking groove. The top of the second lower die has a second blanking groove and an ejector rod is provided inside to eject copper sheets located in the second blanking groove. The upper die punch includes a first punch located above the first lower die and a second punch located above the second lower die. The first punch can impact the strip to the first blanking groove to form copper sheets adhered to the strip. The stamping rod impacts the copper sheets upward to form stamped protrusions or punches. The second punch can impact the copper sheets adhered to the strip to the second blanking groove so that two adjacent copper sheets located in the second blanking groove can overlap.

[0009] Furthermore, a spring is installed between the floating plate and the bottom of the first punching groove to apply a vertically upward elastic force to the floating plate. Multiple springs are provided to ensure the stability of the floating plate's movement in the vertical direction.

[0010] Furthermore, when the spring is in its normal state, the top surface of the floating plate is flush with the top surface of the lower die base, and the spring can push the copper sheet located in the first punching groove out of the first punching groove through the floating plate.

[0011] Furthermore, the depth to which the first punch extends into the first cutting groove is less than the thickness of the copper sheet, to prevent the copper sheet from separating from the strip and to facilitate the subsequent movement of the copper sheet to the top of the second cutting groove along with the bill of materials.

[0012] Furthermore, the stamping machine can adjust the vertical upward movement distance of the stamping rod, and the counter is connected to the stamping machine to count the number of stamping operations. A first groove aligned vertically with the stamping rod is provided below the first punch, and the volume of the first groove is larger than the volume of the stamping protrusion.

[0013] Furthermore, the bottom of the second punching groove is provided with a first platform, a second platform higher than the first platform, and an inclined platform connecting the first platform and the second platform. The bottom of the second punch is provided with a first pressing surface, a second pressing surface higher than the first pressing surface, and an inclined pressing surface connecting the first pressing surface and the second pressing surface, so as to realize the bending and punching of the copper sheet to form a copper sheet with a bending structure.

[0014] Furthermore, the depth of the second punching groove is greater than 20 times the thickness of the copper sheet, so that the copper busbar production device can produce copper busbars containing 20 copper sheets.

[0015] Furthermore, an ejector is provided at the bottom of the ejector rod, and the ejector rod is located directly below the stamping protrusion. The ejector can drive the ejector rod to move in the vertical direction to eject the copper busbar located in the second stamping groove out of the second stamping groove.

[0016] Furthermore, a second groove is provided below the second punch, which is vertically aligned with the ejector rod, and the volume of the second groove is larger than the volume of the stamping protrusion.

[0017] Furthermore, a first punch is mounted to a first hydraulic press to provide power support for the first punch. A second punch is mounted to a second hydraulic press to provide power support for the second punch.

[0018] The beneficial effects of this utility model are:

[0019] 1. By punching protrusions on copper sheets and using a second punch to press adjacent copper sheets together, the manual stacking step is eliminated, thus improving the production efficiency of copper busbars.

[0020] 2. By setting a counter on the first punch and punching holes in the copper sheet when the set number of punches is reached, the number of copper sheets contained in each copper busbar is kept consistent. Attached Figure Description

[0029] In addition, it should be noted that the dynamic terms such as "relative motion" mentioned in the embodiments of this utility model not only refer to changes in position, but also include movements such as rotation and rolling in which the position does not change relative to the position, but the state changes.

[0030] Finally, it should be noted that when a component is said to be "located on" or "set on" another component, it can be on the other component or may have an intervening component at the same time. When a component is said to be "connected to" another component, it can be directly connected to the other component or may have an intervening component at the same time.

[0031] like Figures 1 to 4 The copper busbar production apparatus shown includes a lower die base 1 and an upper die punch 2. The lower die base 1 includes an integrally formed first lower die 11 and a second lower die 12. The top of the first lower die 11 has a first blanking groove 111. Inside the first lower die 11, there is a stamping rod 112 and a stamping machine 113 that drives the stamping rod 112 to move vertically. The stamping machine 113 has a counter connected to the stamping machine 113 to count the number of stampings. A floating plate 114 is provided inside the first blanking groove 111 to facilitate the ejection of copper sheets 4 located in the first blanking groove 111. The top of the second lower die 12 has a second blanking groove 121 and an ejector rod 122 inside to eject the copper sheets 4 located in the second blanking groove 121. The upper die punch 2 includes a first punch 21 located above the first lower die 11 and a second punch 22 located above the second lower die 12. The first punch 21 can impact the strip 3 to the first cutting groove 111 to form a copper sheet 4 adhered to the strip 3. The punching rod 112 impacts the copper sheet 4 upward to form a punching protrusion 41 or a punch hole. The second punch 22 can impact the copper sheet 4 adhered to the strip 3 to the second cutting groove 121 so that two adjacent copper sheets 4 located in the second cutting groove 121 can overlap.

[0032] In one embodiment, the strip 3, driven by the existing conveying mechanism, moves above the lower die base 1 from the first lower die 11 toward the second lower die 12. When the strip 3 moves above the first lower die 11, the first punch 21 moves vertically downward to impact a portion of the strip 3 into the first cutting groove 111, forming a copper sheet 4 adhered to the strip 3. It should be noted that when the first punch 21 impacts the strip 3, the depth to which the copper sheet 4 sinks into the first cutting groove 111 is less than the thickness of the strip 3, so the copper sheet 4 remains adhered to the strip 3, thus achieving an initial impact on the copper sheet 4. When the first punch 21 impacts the strip 3, the impact-formed copper sheet 4 pushes the floating plate 114 downward, and then the stamping press 113 located in the first lower die 11 drives the stamping rod 112 to move vertically upward to punch out a stamping protrusion 41 at the center of the copper sheet 4, and the counter completes one count. When the first punch 21 moves vertically upward, the floating plate 114, under the action of the bottom spring 115, pushes the copper sheet 4 vertically upward so that the copper sheet 4 disengages from the first punching groove 111. This completes the initial stamping of the copper sheet 4.

[0033] The copper sheet 4 adhering to the strip 3 moves above the second lower die 12, and the second punch 22 impacts the copper sheet 4 adhering to the strip 3 to cause the copper sheet 4 to detach from the strip 3 and fall into the second punching groove 121. Simultaneously, the first punch 21 completes the initial punching of the second copper sheet 4.

[0034] After the second copper sheet 4, which is attached to the strip 3, moves above the second lower die 12, the second punch 22 impacts the copper sheet 4 attached to the strip 3 to make the copper sheet 4 detach from the strip 3 and fall into the second punching groove 121. It then moves a first set distance to squeeze the second copper sheet 4 above the first copper sheet 4, so that the stamping protrusion 41 of the first copper sheet 4 is inserted into the stamping groove below the stamping protrusion 41 of the second copper sheet 4, thereby achieving the stacking of the first copper sheet 4 and the second copper sheet 4.

[0035] It should be noted that the counter is connected to the second punch 22 to control the distance the second punch 22 moves vertically downward, so that the second punch 22 can press the new copper sheet 4 onto the top of the previous copper sheet 4.

[0036] In the first lower die 11, when the counter reaches the set value, the stamping press 113 drives the stamping rod 112 to move vertically upward to punch a hole in the center of the copper sheet 4. After the copper sheet 4 with the hole moves above the second blanking groove 121, the second punch 22 presses the copper sheet 4 with the hole onto the top of the previous copper sheet 4, so that the stamping protrusion 41 of the previous copper sheet 4 is inserted into the hole of the copper sheet 4. Then, the ejector 123 located in the second blanking groove 121 drives the ejector rod 122 to move vertically upward to eject the prepared copper busbar located in the second blanking groove 121 out of the second blanking groove 121, realizing efficient production of copper busbars.

[0037] Using this copper busbar production device, copper busbars can be directly produced by stamping the strip 3, eliminating the need for the manual stacking of copper sheets 4, which greatly improves the production quality and efficiency of copper busbars.

[0038] Preferably, a spring 115 is installed between the floating plate 114 and the bottom of the first punching groove 111 to apply a vertically upward elastic force to the floating plate 114. Multiple springs 115 are provided to ensure the stability of the floating plate 114 in the vertical direction.

[0039] Preferably, when the spring 115 is in the normal state, the top surface of the floating plate 114 is flush with the top surface of the lower die base 1, and the spring 115 can push the copper sheet 4 located in the first punching groove 111 out of the first punching groove 111 through the floating plate 114.

[0040] In one embodiment, when the surface of the floating plate 114 is not under pressure, the spring 115 is in its normal state, and the top surface of the floating plate 114 is flush with the top surface of the first lower mold 11.

[0041] Preferably, the depth to which the first punch 21 extends into the first cutting groove 111 is less than the thickness of the copper sheet 4, to prevent the copper sheet 4 from separating from the strip 3, and to facilitate the subsequent movement of the copper sheet 4 above the second cutting groove 121 along with the material list.

[0042] Preferably, the stamping machine 113 can adjust the vertical upward movement distance of the stamping rod 112, and the counter is connected to the stamping machine 113 to count the number of stampings by the stamping machine 113. A first groove 211 is provided below the first punch 21, which is vertically aligned with the stamping rod 112, and the volume of the first groove 211 is larger than the volume of the stamping protrusion 41.

[0043] In one embodiment, when it is necessary to prepare a copper sheet 4 with 20 copper sheets 4, when the value of the counter is 1-19, the stamping machine 113 drives the stamping rod 112 to stamp the copper sheet 4 to form a stamping protrusion 41; when the value of the counter is 20, the stamping machine 113 drives the stamping rod 112 to punch holes in the copper sheet 4.

[0044] Preferably, the bottom of the second punching groove 121 is provided with a first platform 1211, a second platform 1212 higher than the first platform 1211, and an inclined platform 1213 connecting the first platform 1211 and the second platform 1212. The bottom of the second punch 22 is provided with a first pressing surface 222, a second pressing surface 223 higher than the first pressing surface 222, and an inclined pressing surface 224 connecting the first pressing surface 222 and the second pressing surface 223, so as to realize the bending and punching of the copper sheet 4 to form a copper sheet 4 with a bending structure.

[0045] In one embodiment, after the copper sheet 4 adhering to the strip 3 moves above the second lower die 12, the second punch 22 impacts the copper sheet 4 adhering to the strip 3, causing the copper sheet 4 to detach from the strip 3 and fall into the second punching groove 121. The second punch 22 presses the copper sheet 4 to the bottom of the second punching groove 121, causing the copper sheet 4 to bend and deform, forming a bent copper sheet 4. The bottom of the second punching groove 121 and the impact surface of the second punch 22 can be designed according to design requirements.

[0046] Preferably, the depth of the second punching groove 121 is greater than 20 times the thickness of the copper sheet 4, so that the copper busbar production device can produce copper busbars containing 20 copper sheets 4.

[0047] Preferably, the bottom of the ejector rod 122 is provided with an ejector 123. The ejector rod 122 is located directly below the stamping protrusion 41. The ejector 123 can drive the ejector rod 122 to move in the vertical direction to eject the copper busbar located in the second blanking groove 121 out of the second blanking groove 121.

[0048] Preferably, a second groove 221 is provided below the second punch 22, which is vertically aligned with the ejector rod 122, and the volume of the second groove 221 is larger than the volume of the stamping protrusion 41.

[0049] Preferably, the first punch 21 is mounted to the first hydraulic press to provide power support for the first punch 21. The second punch 22 is mounted to the second hydraulic press to provide power support for the second punch 22.

[0050] When the above-mentioned copper busbar production device is used, by punching out the stamping protrusions 41 on the copper sheet 4 and using the second punch 22 to squeeze and stack adjacent copper sheets 4 together, the manual stacking step is eliminated, thus improving the production efficiency of the copper busbar. By setting a counter on the first punch 21 and punching holes in the copper sheet 4 when a set number of times is reached, it is ensured that the number of copper sheets 4 contained in each copper busbar is consistent.
