The present invention relates to a pipe clamp related field, in particular to a titanium metal pipe clamp and a manufacturing method thereof.

The material composition of stainless steel pipe clamps produced in my country is 8% nickel and 92% iron. However, this composition has disadvantages in special environments. The main problem is that the nickel content is relatively low, which results in the limited anti-corrosion ability of stainless steel pipe clamps when facing corrosive environments such as strong acids and strong alkalis. It cannot provide sufficient protection, which has caused limitations for some special environments, such as aerospace, ships or submarine wires and cables.

Furthermore, in the international market, foreign manufacturers usually refer to international standards to select suppliers and products. Since our stainless steel pipe clamps do not meet the lower limit of international standards, our stainless steel pipe clamps cannot be accepted by foreign manufacturers, which limits our competitiveness in the international market.

Therefore, the anti-corrosion effect of stainless steel pipe clamps produced in my country in special environments is limited, and the ingredients do not meet international standards and cannot meet the needs of foreign manufacturers, thus limiting the application scope of pipe clamps and the competitiveness of Chinese products in the international market.

To solve the above problems, the present invention provides a titanium metal pipe clamp and a manufacturing method thereof.

Furthermore, the shell 20 has a first portion 21 and a plurality of second portions 22, each of the second portions 22 can be bent relative to the first portion 21, so that a turning edge 23 is formed between each of the second portions 22 and the first portion 21; a plurality of wire patterns L are provided on the surface of the shell 20 (it should be particularly noted that, in response to the physical properties of titanium metal, the shell 20 is formed by hot forging, and each wire pattern L is formed on the surface of the shell 20 by hot forging), and the texture direction of each wire pattern L is inclined at an angle A to any turning edge 23 of the shell 20, wherein the texture direction of each wire pattern L is a straight line, and the angle A is greater than 0 degrees and less than 180 degrees, so that the texture direction of the wire pattern L is not parallel to any turning edge 23 of the shell 20.

A driving body 30 is made of titanium. The driving body 30 is disposed in the housing 20. The driving body 30 and the belt body 10 are restrained with each other.
