Abstract

The invention relates to the technical field of material processing, and particularly relates to a stress relief and deformation control device for titanium alloy heat treatment. The stress relief anddeformation control device comprises a bearing seat, wherein a driving shaft is rotatably mounted in the bearing seat, and a supporting roller is fixedly mounted on the driving shaft; a spiral threadis formed in the supporting roller, and a balance shaft is fixedly mounted on the supporting roller; the balance shaft is rotatably mounted on a supporting block, and a cavity is formed in the supporting block; a driving bevel gear is fixedly mounted on the balance shaft, and a driven bevel gear is mounted on the driving bevel gear in an engaged mode; and the driven bevel gear is fixedly mountedon a vertical shaft, and a cam is fixedly mounted on the vertical shaft. A titanium alloy pipe is slowly pushed through the supporting roller mounted in an annealing furnace, and the titanium alloy pipe is continuously moved and rotated in the cooling process; and no fixed contact point exists between the pipe and a roller way, so that a workpiece is heated more uniformly without being damaged, and the possibility of pipe deformation is effectively reduced.

[0002] Titanium alloy is an important structural metal. It is widely used in various fields because of its high strength, good corrosion resistance and high heat resistance. In the process of processing titanium alloy pipes, heat treatment is a very important step. Through the annealing furnace for annealing treatment, the titanium alloy pipe can effectively eliminate the internal stress through the whole process of heating, heat preservation and cooling. decline in quality

[0003] Temperature control in the cooling process is one of the important ways of deformation control. The faster the cooling speed, the more uneven the cooling, the greater the stress generated, and the greater the deformation of the mold. Therefore, many annealing furnaces now use staged cooling and quenching, which can Significantly reducing the thermal stress and structural stress generated during metal quenching is an effective way to reduce the deformation of the workpiece. However, when the titanium alloy pipe passes through the annealing furnace, the angle is generally fixed, and the high and low temperatures in the annealing furnace space inevitably have certain The difference, resulting in uneven cooling of titanium alloy pipes, in view of this, we propose a titanium alloy heat treatment stress relief and deformation control device
