Embodiment approach

[0048] According to a preferred embodiment of the present invention, the graphite electrode is provided with a pump body connection through hole and an installation hole, the liquid diffusion pump communicates with the pump body connection through hole, and the installation hole is connected with a cathode wire.

[0049] In the present invention, the setting of the through hole and the realization of the diffusion process can promote ion migration. There is no special limitation on the size of the pump body connection through hole, which can be a conventional choice in the field. Preferably, the pump body connection through hole The diameter of the hole is 20-40mm.

[0050] Exemplarily, as Figure 3-5 As shown, the graphite electrode 2 is provided with a through hole 3 that penetrates from bottom to top; in order to facilitate liquid diffusion, the pump communicates with the through hole 3, preferably, a gap is set below the graphite electrode 2 with the through hole 3 as the ...

Embodiment 1

[0058] (1) Use a hand-held three-dimensional scanner to scan the workpiece at 360°, complete the three-dimensional reconstruction of the workpiece through the scanner equipment, and compare the scanning results with the theoretical model of the workpiece. According to the comparison results, the margin of the weight reduction position is required The upper limit is 5.5mm, the lower limit is 4.8mm, and 4.8mm is used as a reference.

[0059] (2) Insulating glue is applied to parts of titanium alloy complex workpieces that do not require weight reduction;

[0060] (3) Connect the installation hole of the graphite electrode with the cathode wire of the DC power supply, and connect the weight-reducing part of the titanium alloy complex workpiece with the anode wire of the DC power supply. The shape of the graphite electrode is consistent with the shape of the weight-reducing part of the titanium alloy complex workpiece. Matching, connect the through hole (diameter of 30mm) of the p...

Abstract

The invention relates to a titanium alloy workpiece weight reduction method, belongs to the technical field of titanium alloy weight reduction, and solves the problems of high cost, low efficiency and poor precision of a titanium alloy complex workpiece weight reduction method in the prior art. The titanium alloy complex workpiece weight reduction method comprises the following steps that a, the three-dimensional size of a titanium alloy complex workpiece is measured, and the removal size allowance of the portion, needing weight reduction, of the titanium alloy complex workpiece is determined; b, a graphite electrode serves as a cathode, the part, needing weight reduction, of the titanium alloy complex workpiece serves as an anode, a perchloric acid alcoholic solution serves as electrolyte, and electrolysis is conducted. The titanium alloy weight reduction process efficiency is effectively improved, uniformity is good, time and labor cost is low, and the method is suitable for workpieces of complex structures.

Description

technical field [0001] The invention relates to the technical field of titanium alloy weight reduction, in particular to a weight reduction method for titanium alloy workpieces. Background technique [0002] Titanium alloy is widely used in the aerospace field because of its high specific strength, good corrosion resistance, and excellent high and low temperature performance. Casting, welding, forging, and additive manufacturing are common methods for forming titanium alloy workpieces. During the forming process, especially in the casting process, in order to ensure the quality of the molding and the size of the workpiece, in the process of process design, design process subsidies are required The existence of the subsidy will increase the overall quality of the workpiece. For the subsidy exceeding the weight and size requirements, it needs to be removed by machining, manual grinding, pickling and other methods. The existing weight reduction methods for titanium alloy compl...
