In the description of this application, "multiple" or "several" means two or more, unless otherwise explicitly specified.
[0035] Please refer to the following: Figures 1 to 3 The soft copper busbar bending machine provided in the embodiments of this application will now be described. A soft copper busbar bending machine includes:
[0036] Fixed guide groove;
[0037] The bending wheel has a supporting arc surface on its outer periphery that is opposite to the fixed guide groove; the bending wheel also has a bending groove that is opposite to the fixed guide groove and tangentially connected to the supporting arc surface.
[0038] The locking mechanism is provided in the bending groove and is slidably configured to be locked along the extension direction of the bending groove; the locking mechanism has a positioning pin that is adapted to extend into the bending groove.
[0039] The drive mechanism is suitable for driving the bending wheel to rotate;
[0040] During bending, the locking mechanism locks with the bending groove, the soft copper busbar enters the bending groove from the fixed guide groove through the supporting arc surface, the positioning pin is inserted into the bolt hole of the soft copper busbar, and the bending wheel rotates to complete the bending.
[0041] Compared with the prior art, the soft copper busbar bending machine of this application embodiment has a locking mechanism installed on the bending groove of the bending wheel. The positioning pin of the locking mechanism is inserted into the bolt hole of the soft copper busbar in the bending groove, thereby positioning the soft copper busbar and enabling the bending wheel to bend the soft copper busbar at the accurate position. Moreover, by sliding the drive mechanism along the bending groove, the position of the positioning pin on the bending groove can be changed, thereby adapting to the bending of different models of soft copper busbars.
[0042] In practice, the fixed guide groove, bending wheel, and drive mechanism can be mounted on a workbench for easy operation by workers.
[0043] The fixing guide channel can be an elongated channel, with a cross-sectional shape similar to that of the soft copper busbar. The fixing guide channel should have sufficient strength to control one end of the soft copper busbar during bending.
[0044] A bending wheel is a freely rotating wheel, with a supporting arc surface on its outer circumference opposite the exit of the fixed guide groove. A bending groove on the bending wheel is used to fix one end of the soft copper busbar, thus bending the busbar as the bending wheel rotates. The drive mechanism can be an electric motor. However, since the bending wheel typically rotates reciprocally with a rotation angle not exceeding 360 degrees, the drive mechanism can also be a pneumatic or hydraulic cylinder, which drives the bending wheel to rotate through extension and retraction.
[0045] In use, the two ends of the flexible copper busbar are secured in the fixed guide groove and bending groove. The locking mechanism is adjusted to the appropriate position and fixed. Then, the positioning pin of the locking mechanism is inserted into the bolt hole of the flexible copper busbar to position it. Next, the bending wheel is rotated at a certain angle. During the rotation, the bending groove causes the flexible copper busbar to wrap around the supporting arc surface of the fixed guide groove, thus forming the predetermined bending shape. After bending, the positioning pin is removed from the bolt hole of the flexible copper busbar, and the busbar can be removed.
[0046] It should be noted that, in this application, "soft copper busbar" refers to a copper busbar that can typically be bent, and the material is usually a soft material such as copper. The corresponding "hard copper busbar" refers to a copper busbar that cannot typically be bent but can only be cut, and the material is usually a hard material such as brass.
[0047] Please see Figure 1 As a specific embodiment of the soft copper busbar bending machine provided in this application, the soft copper busbar bending machine also includes a rolling roller. In the circumferential direction of the bending roller, the rolling roller is located between the fixed guide groove and the bending groove. The rolling roller is arranged opposite to the supporting arc surface and is pressed against the supporting arc surface by a spring-loaded structure.
[0048] In this embodiment, when the soft copper busbar is bent, a rolling roller is used to roll the bent part of the soft copper busbar wrapped around the support arc surface, which can release the stress of the bent part of the soft copper busbar and reduce the springback deformation of the soft copper busbar.
[0049] Please see Figure 1 As a specific embodiment of the soft copper busbar bending machine provided in this application, the spring-loaded structure includes:
[0050] Fixed sleeve, with an internal mounting cavity;
[0051] The telescopic rod slides through the installation cavity;
[0052] The spring is pushed to extend the telescopic rod out of the fixed sleeve;
[0053] The rolling roller is located at the extended end of the telescopic rod.
[0054] In practice, the fixed sleeve is fixed to the workbench where the bending wheel is located. The telescopic rod is installed axially in the mounting cavity of the fixed sleeve and extends from the front end of the fixed sleeve. The push spring is also installed in the mounting cavity of the fixed sleeve and is located at the rear end of the telescopic rod, which pushes the telescopic rod forward.
[0055] Please see Figure 2 As a specific embodiment of the soft copper busbar bending machine provided in this application, the bending groove is provided with a clearance notch on the side near the bending wheel, and the positioning pin passes through the clearance notch into the bending groove; the clearance notch is provided along the extension direction of the bending groove to allow the positioning pin to pass through different positions in the bending groove.
[0056] In practical implementation, a long clearance notch is provided on the side wall of the bending groove, so that after the locking mechanism slides to any position and is fixed, the positioning pin can be adapted to extend into the bending groove and be inserted into the bolt hole of the soft copper busbar.
[0057] Please see Figure 2 As a specific embodiment of the soft copper busbar bending machine provided in this application, the locking mechanism includes:
[0058] The guide rail is located on the side of the bending groove near the bending wheel and is set along the extension direction of the bending groove;
[0059] The sliding seat slides in conjunction with the guide rail; the sliding seat has a sliding hole facing the clearance notch;
[0060] The mounting sleeve is slidably positioned within the sliding hole and pushed towards the clearance notch by a pin spring; the positioning pin is detachably installed within the mounting sleeve.
[0061] In this embodiment, the locking mechanism can slide along the guide rail to adjust its position. The mounting sleeve utilizes the spring force of the pin spring to drive the positioning pin. Different models of soft copper busbars have different bolt hole diameters. The positioning pin is detachable within the mounting sleeve, allowing for replacement of the positioning pin to match the bolt holes of different models of soft copper busbars, thus achieving more precise positioning of the soft copper busbar.
[0062] In practical implementation, a sliding hole is made on the sliding seat, and the mounting sleeve slides through the sliding hole. A pin spring is installed on the outer sleeve of the mounting sleeve, and the pin spring pushes the mounting sleeve toward the clearance notch. The locating pin can be threaded into the mounting sleeve and moves with the mounting sleeve; when the mounting sleeve moves toward the clearance notch, the front end of the locating pin is inserted into the bolt hole of the soft copper busbar in the bending groove.
[0063] Please see Figure 2 As a specific embodiment of the soft copper busbar bending machine provided in this application, the sliding seat is provided with a locking bolt, which is adapted to abut against the guide rail so as to fix the sliding seat to the guide rail.
[0064] In practice, the locking bolts can be tightened by hand for ease of operation.
[0065] Please see Figure 2 As a specific embodiment of the soft copper busbar bending machine provided in this application, the positioning pin is threadedly connected to the mounting sleeve, and the end of the positioning pin away from the clearance notch is provided with a screw clamp.
[0066] In practice, the screw-on chuck can be hexagonal, Phillips head, or slotted head, allowing the locating pin to be disassembled by engaging it with a wrench, screwdriver, or other tool.
[0067] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
