Problems solved by technology

If you use carbon steel with high hardness that is commonly used at present, directly make the diameter of the dart needle small. During use, once the dart falls to the ground or hits a hard object, the dart needle is easy to break, resulting in the dart being scrapped; High material, such as stainless steel or iron, during use, the dart needle cannot be straightened after being bent and deformed by impact, and can no longer be used, which not only causes waste of materials but also increases the use cost of darts

Abstract

The present invention provides a high-resilience dart, which includes a dart rod, a dart cylinder, a dart wing connected to the tail end of the dart rod, and a dart needle connected to the front end of the dart cylinder, where the dart needle is made of a nickel-titanium alloy material, and the maximum diameter of the dart needle is 1-1.5 mm. The dart is manufactured by steps of smelting, polishing away the skin, rolling into a square shape, polishing away the skin, rolling into wires, performing rotary forging, drawing, straightening, forming and assembling. According to the high-resilience dart of the present invention, the dart needle has high hardness and high resilience, can resist wear and corrosion, and meets requirements of dart fans that the dart needle of the dart is fine and is difficultly deformed and broken, the service life of the dart is prolonged, the use cost of the dart fans is reduced, and the scoring probability of dart players can be improved.

Description

technical field [0001] The invention relates to dart products, in particular to a high-rebound dart and its processing technology. Background technique [0002] Darts usually include a dart shaft, a dart barrel, a dart needle connected to the front end of the dart barrel, and a dart wing located at the tail end of the dart shaft. According to the material of the dart needle at the front end of the dart, the current darts are mainly divided into: The material adopted by the needle is hard metal) and the soft needle dart (the material adopted by the dart needle is plastic). Hard needle darts are used to project hemp targets and paper targets, while soft needle darts are used to project plastic targets and electronic targets. [0003] The diameter of the dart needle of traditional hard needle darts is generally 2.35mm, and it is made of carbon steel or stainless steel. [0004] The practice of dart sports proves that the thinner the dart needle, the easier it is to penetrate ...
