Copper bar bending device

Abstract

The invention discloses a copper bar bending device. The copper bar bending device comprises a base plate, a main shaft, a copper bar bending mechanism, a copper bar locating mechanism, a locking mechanism and a copper bar pressing mechanism. The copper bar bending mechanism comprises a rotating disk, a wire pressing device, a handle and a handle limiting device, wherein the rotating disk is arranged on the main shaft in a sleeved mode, the wire pressing device and the handle are fixed to the radial outer side of the rotating disk, and the handle limiting device is fixed to the base plate. The copper bar locating mechanism comprises a backing plate, a core plate and a guide rail, wherein the backing plate and the core plate are sequentially arranged on the main shaft in a sleeved mode, a copper bar to be bent is longitudinally supported by the guide rail and one side of the backing plate, the inner side of one end of the copper bar to be bent abuts against one side of the core plate, and one end of the wire pressing device abuts against the outer side of one end of the copper bar to be bent. The copper bar pressing mechanism comprises an L-shaped pressing plate, a T-shaped nut and a pressing bolt. The locking mechanism comprises an upper pressing block and a locking nut. The copper bar bending device saves time and labor when operated, and is high in machining efficiency, low in cost, small in bending resistance in the bending process and suitable for single-piece or small-scale production.

Description

technical field [0001] The invention relates to a manual bending device for metal pipes, in particular to a device suitable for manual bending and forming of copper bars of turbine generator rotors, and belongs to the technical field of pressure bending forming machinery. Background technique [0002] The rotor winding of the turbogenerator is made of copper bars with a large width-thickness ratio, and the two ends of the copper bars need to be bent at 90° angles respectively. At present, the copper bars of the rotor windings of the turbogenerator are usually bent by a special bending machine, which has a large bending resistance, and the copper bars are prone to wrinkling, thickening and out-of-tolerance. And the operation is cumbersome, the equipment cost is high, suitable for mass production, not suitable for single piece or small batch production. Contents of the invention [0003] The object of the present invention is to provide a copper bar bending device suitable ...
