Embodiment Construction

[0013] The present invention will be further described below in conjunction with accompanying drawing:

[0014] Such as figure 1 , 2 As shown, the two-way disconnected titanium alloy sheet spring provided by the present invention first grinds the titanium alloy sheet, so that the material surface after final processing has no obvious processing transition traces under 50 times magnification, and the obtained thickness is 0.5 mm titanium alloy flakes 1, titanium alloy flakes 1 with surface roughness ≤ 0.6 μm, flatness < 0.05 mm, and thickness tolerance ≤ 0.05 mm. The upper spiral cutting area 4 and the lower spiral cutting area 5 are set on the titanium alloy sheet 1, and the upper spiral cutting area 4 and the lower spiral cutting area 5 on the titanium alloy sheet 1 are simultaneously stretched by using the upper and lower bidirectional composite stretching dies , forming the upper helical spring 2 and the lower helical spring 3. Both ends of the titanium alloy sheet are s...

Abstract

The invention relates to a bidirectional disconnection type titanium alloy sheet spring, belonging to the technical field of springs. The bidirectional disconnection type titanium alloy sheet spring comprises a titanium alloy sheet and is characterized in that the titanium alloy sheet is provided with an upper spiral cutting region and a lower spiral cutting region, wherein the upper spiral cutting region and the lower spiral cutting region are respectively provided with an upper spiral spring and a lower spiral spring. The bidirectional disconnection type titanium alloy sheet spring disclosed by the invention is of a reasonable and simple structure, is easy to produce and manufacture, and has good usability. Compared with the traditional titanium alloy sheet spring, the bidirectional disconnection type titanium alloy sheet spring disclosed by the invention has the advantages of high surface glossiness, no hidden surface crack, no fatigue break, and durability in use; and the spring is high in the size precision and tensile strength; the bidirectional disconnection type titanium alloy sheet spring is molded at one time through a bidirectional compound stretch drawing die, the deformation coefficient of the spring is reduced to a very small range, the yield of finished product of the spring is greatly improved, the batch production is facilitated, the production efficiency is remarkably improved, and the requirements of the titanium alloy sheet spring for an intelligent drilling rod in a vertical drilling system can be met.

Description

technical field [0001] The invention relates to a spring, in particular to the structure of a two-way disconnected titanium alloy sheet spring for an intelligent drill pipe in a vertical drilling system, and belongs to the technical field of springs. Background technique [0002] High-strength titanium alloy sheet springs are mainly used for smart drill pipes in large-diameter "vertical drilling systems". The smart drill pipes are connected by multi-section drill pipes. The end adopts magnetic induction drill pipe joint. The drill pipe joint is composed of drill pipe groove, ferrite magnetic induction ring, two-way disconnected titanium alloy thin spring and coil. The drill pipe groove is a concave hole opened between the inner and outer walls of the drill pipe. The ferrite magnetic induction ring is also in the shape of a concave groove. The magnetic induction ring is placed in the drill pipe groove, the two-way disconnected titanium alloy thin spring is placed in the ferri...
