Abstract

The invention discloses a suction nozzle of an arc welding torch vacuum cleaner with self-adaptive adjustment, which comprises a dust suction unit, which includes a dust suction part, a telescopic pipe, and an exhaust part. The exhaust part is connected; the adjustment unit includes a telescopic assembly, a steel cable connected to the telescopic end of the telescopic assembly, and an elastic part sleeved on the outside of the telescopic tube, and the other end of the steel cable is connected to the dust-absorbing part Connection: Welding torch, the dust-absorbing part, telescopic tube, exhaust part and telescopic assembly are installed on the welding torch in sequence. When the smoke concentration is high, the suction part moves forward, when the smoke concentration is small, the dust suction part moves backward, and at the same time, according to the smoke concentration, the vacuum negative pressure value is adaptively adjusted; the electrostatic dust removal component is used to absorb dust and prevent pipelines Blocking, on the premise of ensuring the best dust collection effect, it can also ensure that the welding shielding gas is not sucked away, and the welding quality is guaranteed.

Description

technical field [0001] The invention relates to the technical field of welding equipment, in particular to an self-adaptively adjusted suction nozzle of an arc welding torch vacuum cleaner. Background technique [0002] Since the 21st century, environmental protection issues have become one of the hottest words in major news media. Electric welding, as a basic processing technology for thermal processing of metal materials, has been widely used in many industrial enterprises such as metallurgical industry, petrochemical industry, machinery and equipment manufacturing, and shipbuilding. However, many substances such as gas and smoke that are harmful to physical and mental health will be produced in the electric welding production process. Especially when welding is performed in a small space, the concentration of welding smoke will be as high as 100 mg / m3 or more. In some improperly ventilated places The workplace can be as high as 800mg / m3. Such harsh working conditions co...
