Abstract

The invention discloses a current-assisted push bending forming device for a titanium alloy pipefitting and a working method and belongs to the field of preparation of tube blanks. An electrifying device, a sliding device, hydraulic devices connected to two sides of the sliding device and a push bending main die are arranged above a machine table; the push bending main die comprises an upper die and a lower die; a cavity is formed in the lower die, an aluminum alloy tube blank is placed in the cavity, a push rod is arranged on one side of the cavity, and the cavity is connected to the slidingdevice through the push rod; and a bended part of the other side of the cavity is connected to a connector, a mandrel is arranged on the inner side of the bended part of the cavity, the mandrel is fixed to the connector, and the mandrel is matched with a workpiece after push bending in internal shape. The push bending device for current-assisted push bending of a titanium alloy tubular product canachieve bending forming of a titanium alloy workpiece which is large in dimension and high in yield strength by means of a relatively small push bending force and controls the forming precision by adjusting electrical parameters.

Description

technical field [0001] The invention belongs to the field of tube blank preparation, and relates to a push-bending device for titanium alloy pipes, in particular to a current-assisted push-bending forming device and working method for titanium alloy pipes. Background technique [0002] Due to the characteristics of high deformation resistance and low elastic modulus of titanium alloy, titanium alloy pipes have disadvantages such as low forming precision and large springback after processing. It is difficult for existing equipment to process bent pipe products that meet the required size. For example, for titanium alloy pipes with large wall thickness and large diameter, the current general processing method is to heat and bend the two parts of the pipe separately, and then weld them together to form. The processing steps are cumbersome and the working environment used is complicated. In addition, because the forming is divided into two parts, the effect on the control of for...
