technical field

The invention relates to the field of cutting rings, in particular to a high-strength underwater cutting ring.

Background technique

In the salvage process of underwater sunken ships, a product is often required to cut underwater accessories or hulls. The prior art ship cutting tools are easily deformed during use, have poor stability, short service life and high use costs. Therefore, there is a need for an underwater boat cutting appliance with relatively stable performance.

SUMMARY OF THE INVENTION

The purpose of the present invention is to provide a high-strength underwater cutting ring, which has simple structure, fast cutting speed, is not easy to deform the part to be cut, and has a long service life, and solves the above technical problems.

In order to achieve the above-mentioned technical purpose and achieve the above-mentioned technical requirements, the technical solution adopted in the present invention is: a high-strength underwater cutting ring, including a ring body, the ring body includes straight line segments on both sides, and both ends of the straight line segment are The arc-shaped section, the straight-line section and the arc-shaped section are connected end to end to form a back-shaped shape; it is characterized in that: a crosspiece is arranged between the straight-line sections, and the upper and lower end faces of the straight-line section are provided with a number of serrations, which are adjacent to each other. The serrations are equally spaced; the serrations are arranged along the horizontal centerline of the upper end face and the lower end face of the straight segment, and are arranged in a convex shape.

Preferably, the connecting part between the crosspiece and the straight section is transitioned through an arc, which is not only beautiful but also reliable in connection.

Preferably: the thickness of the crosspiece is smaller than the thickness of the straight section of the ring body, and the crosspiece is arranged in the middle position of the ring body, so that the overall structure is more stable.

Preferably, three serrations are symmetrically arranged on the upper end face and the lower end face of each of the straight segments of the ring body.

Preferably: the tooth crests of the saw teeth are set as plane hexagons.

Preferably: the bottom of the sawtooth is set as a rhombus.

The beneficial effects of the invention are as follows: a high-strength underwater cutting ring, compared with the traditional structure: the upper end face and the lower end face of the straight segment are provided with several serrations, and the spacing between adjacent serrations is equal; the said The sawtooth is arranged along the horizontal center line of the upper end face and the lower end face of the straight segment, and is arranged in a convex shape; the effect of cutting the boat is better, the operation time is saved, and the efficiency of cutting the boat is improved; the present invention has a simple structure, good stability, Cutting speed is fast. High efficiency, stable cutting quality, no thermal influence, no deformation of the workpiece to be cut, and easy to operate, can be reused, greatly reduce labor intensity and improve work efficiency when dismantling the hull or accessories; The cost.

Detailed ways

In order to make the invention purpose, technical solutions and beneficial technical effects of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments;

In the accompanying drawings: a high-strength underwater cutting ring, including a ring body 1, the ring body 1 includes straight line segments 1-1 on both sides, and the two ends of the straight line segment 1-1 are arc segments 1-2, and the straight line The section 1-1 and the arc section 1-2 are connected end to end to form a back-shaped shape; it is characterized in that: a crosspiece 2 is arranged between the straight section 1-1, and the upper end face and the lower end face of the straight section 1-1 are both A number of saw teeth 3 are provided, and the spacing between adjacent saw teeth 3 is equal; the saw teeth 3 are arranged along the horizontal centerline of the upper end face and the lower end face of the straight line segment 1-1, and are arranged in a convex shape. The connecting part between the crosspiece 2 and the straight section 1-1 passes through an arc transition; the thickness of the crosspiece 2 is smaller than the thickness of the straight section 1-1 of the ring body, and the crosspiece 2 is arranged in the ring. The middle position of the main body 1; the upper end face and the lower end face of the linear segment 1-1 of each described ring body are symmetrically provided with three serrations 3; The bottom of the sawtooth 3 is set to a rhombus.

The specific implementation of the present invention: the integral cutting mechanism is composed of a cutting ring, a connecting ring and a traction device. When weaving the ring, connect the cutting ring and the connecting ring in turn, and the cutting ring and the connecting ring are perpendicular to each other; when in use, connect the cutting ring at both ends to the traction device to complete the installation.

The cutting ring of the present invention is produced by R5 grade material, and has the characteristics of high strength, toughness, long service life and the like. Use this cutting ring to cut fast. High efficiency, stable cutting quality, no thermal influence, no deformation of the workpiece to be cut, and easy to operate, can be reused, greatly reduce labor intensity and improve work efficiency when dismantling the hull or accessories; The cost.

The above-mentioned embodiments are only descriptions to clearly illustrate the present invention, rather than to limit the embodiments. For those skilled in the art, changes or changes in other different forms can also be made on the basis of the above-mentioned descriptions. It is not necessary and impossible to list all the embodiments here, and the obvious changes or changes derived therefrom still fall within the protection scope of the present invention.
