Welding machine output mechanism for special shaped finned tube

Abstract

The invention discloses a welding machine output mechanism for a special shaped finned tube. The welding machine output mechanism comprises a conductive copper block component, a clamp component and ashell insulating component; the conductive copper block component comprises a lifting air cylinder, a first middle connection insulating block, a second middle connection insulating block, a third middle connection insulating block, an air cylinder sliding rail, a conductive copper block and an output row; the lifting air cylinder drives the conductive copper block and the output row to do up-down stroke action on the air cylinder sliding rail; the clamp component comprises a clamp air cylinder component, a clamp middle insulating fixing piece and a clamp conductive copper block; the extension part of the conductive copper block of the conductive copper block component extends into the clamp component; when the clamp air cylinder component operates, the conductive copper block of the conductive copper block component and the clamp conductive copper block of the clamp component are connected in a clamping manner; and the lifting air cylinder and the clamp air cylinder component are perfectly combined, so that high-frequency electricity can be transmitted to the fin side part of the special shaped finned tube and the surface of a steel pipe at the fin bonding part through the welding machine output mechanism, and stability and reliability of electric conduction are ensured.

Description

technical field [0001] The invention relates to the field of welding, in particular to a welder output mechanism for special-shaped finned tubes. Background technique [0002] With the continuous development of the domestic machinery manufacturing industry, high-frequency online contact welding welding equipment has been vigorously developed, especially the rapid development of high-frequency welded pipes and high-frequency welded section steel, so the requirements for welding quality of different profiles are also getting higher and higher. Need To meet the needs of different products. [0003] The existing domestic high-frequency online contact welding welding equipment has the following shortcomings: thin structure, poor heat dissipation, can only meet the requirements of small specifications, and can only be used for welding thin-walled ordinary carbon steel finned tubes; The loadable output high-frequency power is small, and it cannot meet the output of large resonance...

[0003] The existing domestic high-frequency online contact welding welding equipment has the following shortcomings: thin structure, poor heat dissipation, can only meet the requirements of small specifications, and can only be used for welding thin-walled ordinary carbon steel finned tubes; The loadable output high-frequency power is small, which cannot meet the output of large resonance current and high power, and cannot meet the production of materials with low magnetic permeability such as stainless steel, so the types of products that can be produced and the release of production capacity are limited.
