Description

Technical Field

[0001] The utility model relates to the technical field of electric control cabinet processing, in particular to a busbar bending device. Background Art

[0002] The busbar is the input bus in the electric control cabinet. It needs to be bent according to the line layout requirements during processing. Common bending includes thickness direction bending, that is, the busbar after bending has a multi-fold structure, and plane bending. When bending along the thickness direction, warping often occurs due to lack of positioning, which affects the bending effect of the busbar. In addition, the warping during bending often affects the installation accuracy of the busbar. Utility Model Content

[0003] The utility model provides a busbar bending device to solve the deficiencies of the prior art, and avoids the problem of warping during bending by positioning the busbar, thus having strong practicality.

[0004] In order to achieve the purpose of this utility model, the following technologies are proposed:

[0005] A busbar bending device includes a bottom plate, on which a plurality of support rods are mounted. A bending block is provided at the upper end of the support rod, and the bending block is in a rectangular structure. Bending grooves are provided on two adjacent side walls of the bending block, and the bending grooves are in an L-shaped structure, and arc surfaces are formed at the corners. In order to prevent the bending foot of the busbar from being in a right-angle state after bending, a pair of L-shaped plates are movably provided on the bending block, and the L-shaped plates are distributed up and down, and bending splints are provided at both ends of the L-shaped plates, and the bending splints are located in the bending grooves. A mounting plate is installed on the bottom plate, and a bending cylinder is installed on the upper end of the mounting plate, and a rotating head is installed on the movable end of the bending cylinder, and an action wheel is rotatably provided at the other end of the rotating head. The busbar is completely positioned by the provided bending clamp to avoid warping during bending deformation, and the action wheel acts on the side wall of the busbar during bending to avoid adverse effects on the appearance of the busbar due to friction and the like during the bending process. Of course, in order to avoid deformation of the arc surface of the busbar during bending, an arc groove can be formed on the outer wall of the action wheel.

[0006] Furthermore, a plurality of guide rods are provided on the bending splint, and the guide rods pass through the bending block, and the guide rods play a further guiding role in the movement of the bending splint.

[0007] Furthermore, a screw block is provided on the L-shaped plate, and a screw rod is provided on the screw block located in the same vertical direction, the threads at both ends of the screw rod have opposite rotation directions, and a rotating seat is provided at both ends of the screw rod for rotation, and the rotating seat is installed on the bending block, and a driven bevel gear is provided at the upper end of the screw rod, and the driven bevel gear meshes with a driving gear, and the driving gears are driven by a rotating shaft, and a concave seat is rotatably provided on the rotating shaft, and the concave seat is installed on the bending block. The above method can make different parts of the bending clamp plate move at the same time, and the two clamp plates can move at the same time when clamping, thereby ensuring that the busbar is located at a position where it can be acted by the action wheel.

[0008] Furthermore, an anti-slip sleeve is provided on the rotating shaft to facilitate operators to rotate the rotating shaft.

[0009] The advantages of the above technical solution are:

[0010] The utility model facilitates the bending of the busbar within the plane where the busbar is located, and can avoid the problem of warping during bending. BRIEF DESCRIPTION OF THE DRAWINGS
