Description

Technical Field

[0001] This utility model relates to the technical field of copper busbar processing, and in particular to a device for bending and forming copper busbars for cabinets. Background Technology

[0002] Inside power distribution cabinets, switch cabinets and other equipment, a large number of copper busbars are used as conductive connectors. In order to adapt to different electrical layouts and spatial structures, these copper busbars often need to be bent at various angles.

[0003] Existing cabinet copper busbar bending and forming devices, such as the copper busbar bending equipment disclosed in utility model patent application number 202421817422.3, mainly include a processing table and a copper busbar to be bent. The copper busbar is set above the processing table, and two positioning mechanisms are set on the processing table, with the two positioning mechanisms respectively set at both ends of the copper busbar. In use, under the action of the return spring, two movable clamps squeeze and position the copper busbar from both sides, so that each time the copper busbar is placed, it can be quickly positioned in the same area between the first bending piece and the second bending piece.

[0004] However, existing copper busbar bending devices have poor fixing effect on copper busbars, and the copper busbars are prone to displacement, which affects the bending effect. Moreover, the bent copper busbars are easy to get stuck in the clamping mechanism and are difficult to remove. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a cabinet copper busbar bending and forming device that not only facilitates the positioning and clamping of copper busbars, ensuring the effect of subsequent bending and forming, and preventing the copper busbars from shifting during the bending process, but also facilitates the ejection of the bent copper busbars, preventing the copper busbars from getting stuck in the clamping mechanism.

[0006] This utility model discloses a copper busbar bending and forming device for cabinets, including a workbench; it also includes a clamping mechanism, two sets of pushing mechanisms, two sets of bending mechanisms, and a discharge mechanism. The clamping mechanism is installed on the workbench and clamps the copper busbar. The two sets of pushing mechanisms are installed opposite each other on the workbench and push the two sets of bending mechanisms closer together. The two sets of bending mechanisms are respectively installed on the two sets of pushing mechanisms and bend the copper busbar into shape. The discharge mechanism is installed on the workbench and pushes the copper busbar out. The operator places the copper busbar on the clamping mechanism, which positions and clamps the copper busbar. The operator selects the appropriate two sets of bending mechanisms and installs them on the two sets of pushing mechanisms. The operator starts the two sets of pushing mechanisms to push the two sets of bending mechanisms closer together. The two sets of bending mechanisms bend and shape the copper busbar. After forming, the two sets of pushing mechanisms reset, and the discharge mechanism pushes the copper busbar upward to discharge it.

[0007] Preferably, the workbench includes four sets of adjustable support legs, a desktop, and control buttons. The tops of the four sets of adjustable support legs are connected to the bottoms of the adjustable support legs, and the control buttons are installed on the desktop. The operator adjusts the desktop to a horizontal position using the four sets of adjustable support legs, and then controls the bending of the copper busbar using the control buttons.

[0008] Preferably, the clamping mechanism includes a servo motor, a reducer, a bidirectional lead screw, two sets of sliders, two sets of back plates, and four sets of positioning rods. A groove is formed in the tabletop, and the servo motor is installed within this groove. The power output end of the servo motor is connected to the power input end of the reducer, which in turn is connected to the power input end of the bidirectional lead screw. Both sets of sliders are slidably installed within the grooves in the tabletop and connected to the bidirectional lead screw via threaded transmission. The bottom ends of the two sets of back plates are connected to the top ends of the two sets of sliders, respectively. Each set of sliders is equipped with two sets of positioning rods. The operator places the copper busbar between the four sets of positioning rods and starts the servo motor. The servo motor drives the bidirectional lead screw to rotate via the reducer. The bidirectional lead screw causes the two sets of sliders to move closer together, which in turn moves the two sets of back plates. The two sets of back plates abut against both ends of the copper busbar, positioning it at the machining center. During processing, the two sets of sliders continuously move closer together to ensure the bending effect.

[0009] Preferably, the four positioning rods are made of rubber. The copper busbar may deform at both ends during the bending process. The four positioning rods are made of rubber, which can avoid hard friction between the positioning rods and the copper busbar and protect the copper busbar.

[0010] Preferably, the pushing mechanism includes a support plate, a first hydraulic cylinder, a positioning frame, a connecting mother block, and a positioning slider. The bottom end of the support plate is connected to the top end of the table. The first hydraulic cylinder is mounted on the support plate, and the oil circuits of the first hydraulic cylinders of the two pushing mechanisms are connected. A synchronization valve is installed on the oil circuit. The positioning frame is mounted on the support plate and has a sliding groove. The connecting mother block is mounted on the first hydraulic cylinder, and the positioning slider is mounted on the connecting mother block and slides within the sliding groove of the positioning frame. Different bending mechanisms are selected according to the bending requirements of the copper busbar. The bending mechanism is connected to the connecting mother block, and the two sets of first hydraulic cylinders are started synchronously, pushing the two sets of connecting mother blocks closer together. The connecting mother block drives the positioning slider to slide within the positioning frame, and the positioning slider cooperates with the positioning frame to ensure the stability of the movement.

[0011] Preferably, the bending mechanism includes a connecting male block, a fixing bolt, a bending die, a connecting rod, and a connecting seat. The connecting male block is slidably installed inside the connecting female block. Positioning holes are opened on the connecting female block and the connecting male block. The fixing bolt is installed in the positioning holes. The bending die is installed on the connecting male block. The bottom end of the connecting rod is connected to the top end of the bending die, and the bottom end of the connecting seat is connected to the top end of the bending die. The operator selects a suitable bending mechanism according to the bending requirements, slides the connecting male block and the connecting female block together, inserts the fixing bolt into the positioning holes of the connecting male block and the connecting female block to fix them together. The two sets of connecting female blocks drive the two sets of bending dies to approach and bend the copper busbar for shaping. The connecting rods and connecting seats on the two sets of bending mechanisms cooperate to ensure the bending effect of the two sets of bending dies.

[0012] Preferably, the discharge mechanism includes two sets of second hydraulic cylinders and a discharge frame. Both sets of second hydraulic cylinders are mounted on a table, and a synchronization valve is provided on the oil circuit of the two sets of second hydraulic cylinders.
