Description

TECHNICAL FIELD

[0001] The utility model relates to aluminium busbar production equipment technical field, concretely relates to the clamp for shifting aluminium busbar processing station. BACKGROUND

[0002] Aluminium busbar refers to the large current conducting device for power transmission and distribution, usually made of pure aluminium or aluminium alloy. Aluminium busbar is widely used in power system due to its good conductivity, light weight and cost effectiveness. In order to meet the demand of large current transmission and improve the heat dissipation performance, in order to reduce the resistance and reduce the heat generated when the current passes, the aluminium busbar needs to have enough cross section, so a large volume of aluminium busbar is used. The mass of this kind of aluminium busbar usually reaches hundreds of kilograms or even hundreds of kilograms, and then the aluminium busbar needs to be cut, polished and rolled in multiple steps, and different processing steps need to be carried out in different stations, so the transfer of aluminium busbar station is usually carried out by using a row of hangers with a shear clamp to clamp the aluminium busbar and move it to transfer the processing station. However, the shear clamp is based on the principle of lever, when the row of hangers moves up to pull the shear clamp to exert force to make the supporting arm close, so that the clamping end can clamp the aluminium busbar. However, when clamping the aluminium busbar, the surface of the aluminium busbar is flat, so slippage and shaking may occur during clamping, which may cause the aluminium busbar to fall off the clamp. Since the mass of this kind of aluminium busbar is large, if it falls off, it is easy to cause safety accidents, so there is an urgent need for a clamp that can stably clamp large volume of aluminium busbar.
