Description

Technical Field

[0001] The invention relates to the technical field of titanium alloy ball valves, in particular to a titanium alloy ball valve component metal processing tool and a processing method. Background Art

[0002] Introduced in the 1950s, ball valves offer the ability to rotate 90 degrees. They feature a spherical plug body with a circular hole or channel running through its axis. With the rapid advancement of science and technology, ball valve production processes and product structures have continuously improved. In just 40 years, ball valves have rapidly become a major valve type. Ball valves are primarily used in pipelines to shut off, distribute, and redirect the flow of media. They achieve a tight seal with just a 90-degree rotation and minimal torque.

[0003] The patent application number 202320805858.X discloses a four-axis tooling for processing ball valves. The problem raised in the background technology is that the existing equipment does not have an internal clamping structure, and only uses the method of squeezing and clamping on both sides to fix the ball valve. During processing, the turning tool frequently contacts the surface of the ball valve, and the ball valve is displaced, which reduces the processing accuracy and affects the quality of the finished product. It is provided with a rotating shaft, a mounting seat, a sliding rod, a bidirectional threaded rod, a turntable, a positioning rod and a slider. By rotating the turntable counterclockwise, the turntable drives the bidirectional threaded rod, and the bidirectional threaded rod drives The two sliders move away from each other, and the two sliders drive the two clamping rods to move away from each other, and the two clamping rods drive the two anti-skid pads. When the anti-skid pads fit the inner wall of the ball valve, the turntable stops rotating, and the internal clamping fixation of the ball valve is completed. However, there are several problems: the outer surface of the ball valve needs to be frequently contacted with the turning tool for cutting, but the inner surface of the ball valve also needs to be cut. When the inner clamp is fixed, the inner surface cannot be cut. At this time, the operating table needs to be replaced to fix and cut the outside of the ball valve again. This is very troublesome and reduces efficiency. In addition, replacing the operating table is prone to operator errors, resulting in product scrapping. In order to solve the above problems, a titanium alloy ball valve component metal processing tool and processing method are proposed. Summary of the Invention
