Example Embodiment

[0030] The embodiment of the present invention: the blank inner diameter size of the titanium alloy cylindrical spinning part 10 is 1500-2500mm, the blank wall thickness size is 45mm, and the effective length is 700mm.

[0031] As attached Figure 1-4 As shown, the heated titanium alloy cylindrical spinning part 10 is installed in the spinning die 1, and the cylindrical spinning part 10 is attached to the ring gear 7.

[0032] The spinning die 1 is directly connected to the spindle of the spinning machine tool. The spinning die 1 makes a rotary movement during the spinning process, which is the main movement in the spinning process. The spinning wheel device 4 is connected to the sliding seat of the spinning machine tool. Feed motion during processing. During spinning, the rotation of the spindle of the spinning machine tool drives the spinning die 1 to rotate, and the spinning die 1 drives the ring gear 7 and the cylindrical spinning part 10 to rotate.

[0033] The rotating wheel ...

Abstract

The invention relates to a device and method for spinning a cylindrical titanium alloy part. The device comprises a spinning mould 1, a spinning wheel device 4, a fluted disc device 7 and a spinning lathe. The spinning mould 1 is mainly used for clamping the cylindrical spinning part 10 and limiting the flow of materials in the process of metal spinning. The fluted disc device 7 is used for fixing the cylindrical part in the process of metal spinning to prevent relative rotation between the cylindrical spinning part 10 and the spinning mould 1. The spinning wheel device 4 is used for applying spinning force to the cylindrical spinning part 10 in the process of metal spinning, so that plastic deformation is carried out on a titanium alloy spinning workblank, and the required shape and the required size of the cylindrical spinning part 10 are achieved. According to a method for manufacturing the cylindrical spinning part 10, before the spinning process, the spinning mould 1 and the cylindrical spinning part 10 are heated up to a certain temperature, the process of mould filling is completed, then spinning operation is carried out, after the spinning mould 1 and the cylindrical spinning part 10 are cooled, detaching is performed, and finally the high-precision high-quality cylindrical spinning part 10 is obtained.

Description

technical field [0001] The invention relates to a device and method for spinning cylindrical parts, in particular to a spinning device and a processing method for large titanium alloy cylindrical parts. Background technique [0002] Due to its excellent corrosion resistance, titanium alloys are widely used in metallurgy, seawater desalination, and chemical equipment, such as cathode rollers in hydrometallurgy, evaporators for seawater desalination, reaction vessels for chemical equipment, heat exchanger etc. Most of these products have high requirements on the corrosion resistance of parts, and are mostly made of titanium alloy with strong corrosion resistance, and the shape is mainly cylindrical. The traditional processing method of titanium alloy cylinder is mostly the sheet metal roll welding technology. Although the roll welding technology can complete the forming of this type of cylinder, there are many shortcomings. First of all, there will be a certain difference be...
