Abstract

The invention discloses a titanium alloy irregular wire material straightening device and a straightening method thereof. The straightening device comprises a tube-type heating furnace which is placed horizontally, wherein a wire conveying pipe with one closed end is nested in a center hole of the tube-type heating furnace; the two ends of the wire conveying pipe respectively extend out of hole openings of the two ends of the center hole; a circular hole a is formed in the end face of the closed end of the wire conveying pipe; a pipe cover is mounted at an open end of the wire conveying pipe; a circular hole b is formed in the end face of the pipe cover; one end of a titanium alloy irregular wire material is connected to an unwinding wheel; the other end of the titanium alloy irregular wire material sequentially penetrates through the circular hole a and the circular hole b and then is connected to a winding wheel driven by a motor; a circular hole c is formed in the wire conveying pipe; an inert gas tank is communicated with the circular hole c through a gas transmission hose; the circular hole a and the circular hole b are coaxial, and the hole diameter of the circular hole a and the hole diameter of the circular hole b are the same and are 1 to 2 times the cross section size of the titanium alloy irregular wire material. According to the titanium alloy irregular wire material straightening device and the straightening method thereof, the problem that the existing straightening methods cannot be used for straightening materials of irregular cross sections is solved, and the requirements of titanium alloy irregular wire material straightening on surface quality and mass production are met.

Description

technical field [0001] The invention belongs to the technical field of finishing processing equipment for titanium alloy materials, relates to a straightening device for titanium alloy special-shaped wires, and also relates to a straightening method for straightening titanium alloy special-shaped wires by using the straightening device. Background technique [0002] Titanium alloy materials have high specific strength and good processing performance, and can manufacture thinner and finer structural devices. Its heat dissipation performance and surface texture are also better; at the same time, compared with ordinary metal materials, titanium alloys have low density and corrosion resistance. Good performance, can meet the coating and coating process in corrosive medium. Based on the above characteristics, titanium alloy is widely used as a structural material in 3C electronic products with Computer, Communication and Consumer Electronics as the core applications.
