Description

Technical Field

[0001] The utility model relates to the technical field of copper bar processing, in particular to a copper bar bending device. Background Art

[0002] Copper busbar, also known as copper busbar or copper busbar, is a long conductor with a rectangular or chamfered (rounded) rectangular cross-section. Nowadays, copper busbars with rounded corners are commonly used to avoid tip discharge. In power and traction substation systems, there are many hard busbar constructions, especially in complete sets of distribution equipment, which have been widely used.

[0030] See also Figure 1-Figure 4 The utility model provides a copper busbar bender, which, in practical application, comprises: a pushing assembly 1, and a clamping assembly 2 and a limiting assembly 3 connected to the pushing assembly 1.

[0031] In some embodiments, the output end of the pushing component 1 abuts against the bending part of the copper busbar to be bent, and the two ends of the copper busbar to be bent are limited by the limiting component 3, and the pushing component 1 is used to push the bending part of the copper busbar to be bent, so that the copper busbar to be bent is bent.

[0032] Furthermore, the pushing assembly 1 includes a pushing member 11, a fixing frame 12 provided on the pushing member 11, and an abutment member 13 connected to the pushing member 11. In some embodiments, the pushing member 11 can be a hydraulic jack, and the output piston of the hydraulic jack pushes the abutment member 13 by shaking the rocker of the hydraulic jack; the fixing frame 12 is provided on the pushing member 11 and is connected to the limiting assembly 3; the abutment member 13 has a certain three-dimensional shape, so that after the abutment member 13 abuts against the bending part of the copper busbar to be bent, the copper busbar to be bent can be bent into a desired shape.

[0033] In some embodiments, the clamping assembly 2 includes two groups of clamping plates 21 that are relatively horizontally arranged up and down. The clamping plates 21 are connected to the abutment 13. There is a certain distance between the two groups of clamping plates 21 that are relatively arranged up and down. On the one hand, they are used to accommodate the copper busbar to be bent. On the other hand, they can also limit the copper busbar to be bent to reduce the possibility of up and down vibration of the copper busbar to be bent during the bending process.

[0034] In some embodiments, the limiting assembly 3 is used to limit the two ends of the copper busbar to be bent, and includes: a first wing plate 31 and a second wing plate 32 arranged opposite to each other up and down, a first limiting column 33 movably connected to the first wing plate 31 and the second wing plate 32, and a clamp 34 adapted to the first limiting column 33. Furthermore, the first wing plate 31 is connected to the fixing frame 12, and the second wing plate 32 is hinged to the fixing frame 12, so that the second wing plate 32 can be flipped with the hinge with the fixing frame 12 as the axis.

[0035] Furthermore, the first wing plate 31 and the second wing plate 32 are each provided with a plurality of through holes, and the first limiting column 33 is arranged on both sides of the first wing plate 31 and the second wing plate 32. For example, the first limiting column 33 can be detachably connected to the first wing plate 31 and the second wing plate 32 respectively by means of nuts or the like, and the first limiting column 33 is used for limiting after being abutted against the two ends of the copper busbar to be bent, so that the pushing assembly 1 pushes the bending part of the copper busbar to be bent to complete the bending process of the copper busbar.

[0036] Furthermore, the clamp 34 is movably connected to the first limiting column 33 to increase the contact area between the limiting component 3 and the copper busbar to be bent, thereby reducing the possibility of dents appearing on the copper busbar after bending due to the small contact area after the copper busbar to be bent abuts against the first limiting column 33.

[0037] In some embodiments, the cross-sectional shape of the clamp 34 is F-shaped, which includes a recessed connecting groove 341 and a flat abutting surface 342, wherein the connecting groove 341 is connected to the first limiting column 33, and the abutting surface 342 abuts against the copper bus to be bent, thereby increasing the contact area between the first limiting column 33 and the copper bus to be bent through the abutting surface 342.

[0038] Furthermore, the limiting assembly 3 further includes: a connecting piece 35, and a second limiting column 36 detachably connected to the connecting piece 35. In some embodiments, the second limiting column 36 is connected to the first wing plate 31 and the second wing plate 32, and then abuts against a surface of the two ends of the copper bar to be bent away from the clamp 34 for limiting, thereby improving the limiting effect of the copper bar bending device on the copper bar during the copper bar bending process. In some embodiments, the connecting piece 35 can be square steel.

[0039] Furthermore, the limit assembly 3 also includes: support tubes 37, the number of the support tubes 37 is multiple groups, one end of the support tubes 37 is respectively connected to the first wing plate 31 or the second wing plate 32, so that the support tubes 37 can support the bent copper busbar after being horizontally arranged, thereby reducing the possibility of the copper busbar vibrating up and down.
