Description

Technical Field

[0001] This utility model relates to the technical field of copper busbar manufacturing equipment, specifically a manufacturing equipment for irregularly shaped copper busbars with 90-degree rotational bending. Background Technology

[0002] As a core component for high-current conduction, copper busbars are the preferred alternative to conductors when the current load is ≥250A. Due to their strong current-carrying capacity and low resistance, they are widely used in high and low voltage electrical appliances, switch contacts, power distribution equipment, and busbar trunking. Among them, rotary-bent irregular-shaped copper busbars are specifically designed for special locations where the direction of current transmission needs to be changed.

[0003] Currently, attached Figure 1 The 90-degree rotating and bending irregular copper busbar body 5 (mold-pressed type) shown faces technical bottlenecks in its manufacturing process. Traditional processes employ a step-by-step approach: requiring the sequential use of manual bending machines, indexing heads, stamping dies, and other equipment, involving multiple steps such as pre-bending, manual rotation positioning, and secondary forming. This method has the following problems: First, multiple clamping and transfer operations lead to large cumulative positioning errors, making it difficult to meet high-precision conductivity requirements; second, manual operation relies on experience and is inefficient; third, traditional molds have poor adaptability, limited ability to form three-dimensional curved surfaces of irregular structures, and a high scrap rate.

[0004] To overcome the aforementioned technical challenges, the technical team in this field has developed a manufacturing device for irregularly shaped copper busbars with 90-degree rotational bending. Utility Model Content

[0008] Furthermore, two sets of ear plates are symmetrically arranged on both sides of the lower mold. Each set of ear plates consists of two ear plates arranged at intervals. An insert block is provided on both sides of the upper mold. The insert block is inserted between two ear plates on the same side. Both ear plates on the same side are provided with threaded holes and threaded with connecting bolts. One end of the connecting bolt passes through the insert block.

[0009] Furthermore, the extending support includes an extending plate and a conical head disposed at one end of the extending plate. The conical head is adapted to the transition arc groove and the horizontal straight groove. The conical head is inserted from one end of the copper busbar body and extends sequentially into the horizontal straight groove and the transition arc groove of the rear clamp.

[0010] Furthermore, the rotating fixing front clamp includes a cylindrical connector and a through-hole provided on the cylindrical connector, the depth of which is adapted to the copper busbar body.

[0011] Furthermore, the rotary drive mechanism is a lathe, and the cylindrical block is clamped and fixed by the lathe chuck.

[0023] Please see Figure 1-7 A manufacturing apparatus for a 90-degree rotating and bending irregularly shaped copper busbar includes an inserting and opening member 1, a rear clamp 2, a rotating and fixing front clamp 3, an adjusting and locking bolt 4 that is threaded to the upper side of the rear clamp 2, a transverse drive mechanism, and a rotating drive mechanism arranged sequentially along the central axis. The rotating drive mechanism is connected to the rotating and fixing front clamp 3 via a chuck, and the output end of the transverse drive mechanism is connected to one end of the inserting and opening member 1. One end of the adjusting and locking bolt 4 extends into the interior of the rear clamp 2 to clamp and fix the copper busbar body 5 inside the rear clamp 2. The other end of the inserting and opening member 1 extends into one end of the rear clamp 2 via the transverse drive mechanism.

[0024] The rear clamp 2 includes a lower die 8, an upper die 9 that fits tightly against the upper side of the lower die 8, a groove 10, a transition arc groove 16, and a horizontal straight groove 15 respectively provided on opposite sides of the upper die 9 and the lower die 8; the groove 10, the transition arc groove 16, and the horizontal straight groove 15 are connected in sequence to form a channel for the copper busbar body 5 to pass through; the horizontal straight groove 15 corresponds to the side that extends into the support member 1; the adjusting locking bolt 4 is threadedly connected to the upper die 9 and one end extends into the channel of the groove 10. The depth of the groove 10 is 1 / 2 of the thickness of the copper busbar body 5 and is symmetrically arranged along the width direction of the copper busbar to limit the initial horizontal displacement of the copper busbar. When the transition arc groove 16 bends the copper busbar body 5, it avoids stress concentration at the bending point of the copper busbar body 5, which could lead to cracking.

[0025] Two sets of ear plates are symmetrically connected on both sides of the lower mold 8. Each set of ear plates consists of two ear plates 11 arranged at intervals. An insert block 12 is connected to both sides of the upper mold 9. The insert block 12 is inserted between the two ear plates 11 on the same side. The two ear plates 11 on the same side are provided with threaded holes and threaded with connecting bolts 13. One end of the connecting bolt 13 passes through the insert block 12.

[0026] The extension support 1 includes an extension plate 6 and a conical head 7 connected to one end of the extension plate 6. The conical head 7 is adapted to the transition arc groove 16 and the horizontal straight groove 15. The conical head 7 is inserted from one end of the copper busbar body 5 and extends into the horizontal straight groove 15 and the transition arc groove 16 of the rear clamp 2 in sequence.

[0027] The rotating fixing clamp 3 includes a cylindrical connector 17 and a through-hole 14 opened on the cylindrical connector 17. The depth of the through-hole 14 is adapted to the copper busbar body 5. The cylindrical connector 17 consists of two symmetrically arranged parts, and the through-hole 14 is formed by two symmetrically arranged slots opened on these two parts respectively.

[0028] The rotary drive mechanism is a lathe, but any device capable of driving rotation (driven by a power source such as a servo motor, hydraulic motor, or geared motor) can also be used. The cylindrical connecting block 17 is clamped and fixed by a lathe three-jaw chuck. To control the rotation angle, a stop device is set at the 90-degree position of the rotating and fixing front clamp 3. When the rotating and fixing front clamp 3 reaches this 90-degree angle, the device will automatically stop rotating.

[0029] The lateral drive mechanism is a pneumatic cylinder or a hydraulic cylinder.

[0030] Working Process and Principle: When processing the processed copper busbar body 5, firstly, rotate and remove the two connecting bolts 13, then remove the upper mold 9 of the rear clamp 2 from the lower mold 8. Next, pass the head end of the processed copper busbar body 5 through the through-hole 14 of the rotating and fixing front clamp 3, so that the part of the copper busbar body 5 near the head end enters the groove 10 of the lower mold 8, thereby determining the part of the copper busbar body 5 that needs to be bent. Afterwards, place the upper mold 9 back on the lower mold 8, and insert the two insert blocks 12 connected to the upper mold 9 into the two ear plates 11 on the same side, respectively. Then, screw the two connecting bolts 13 into the two ear plates 11 on the same side and through the middle insert block 12, completing the initial fixation of the copper busbar body 5 by the upper mold 9 and the lower mold 8. During this process, the two grooves 10 on the upper mold 9 and the lower mold 8 play a preliminary positioning role for the copper busbar body 5. Subsequently, rotate the adjusting locking bolt 4 downwards to press and adjust the positioning of the copper busbar body 5 located in the channel. Next, the rotary drive mechanism (lathe) is activated, causing the rotating fixed front clamp 3 to rotate 90 degrees, while the rear clamp 2 remains stationary. At this point, the rotary bending section of the copper busbar body 5 is completed. Then, the transverse drive mechanism (cylinder or hydraulic cylinder) connected to the extending support 1 is activated, causing the conical head 7 to move between the upper and lower copper busbar bodies 5 and advance into the upper and lower horizontal straight grooves 15 and the transition arc groove 16. This tightly fits the upper and lower layers of the copper busbar body 5 onto the two horizontal straight grooves 15 and the transition arc groove 16, thus bending it to the required size and shape. After completion, the transverse drive mechanism (cylinder or hydraulic cylinder) drives the conical head 7 back to its initial position. Finally, the upper die 9 of the rear clamp 2 is removed, and the machined copper busbar body 5 is taken out.

[0031] In summary, this device can easily process the irregularly shaped copper busbar body 5 with 90-degree rotation and bending, and has the advantages of simple structure, convenient operation and high production efficiency, thus improving production efficiency.

[0032] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
