Description

Technical Field

[0001] This utility model relates to the field of welding equipment, specifically a transformer core welding device. Background Technology

[0002] With the development of power systems and the widespread application of transformers in power transmission and distribution, the manufacturing quality of transformer cores has become particularly important. The transformer core is one of the core components of a transformer, and its welding quality directly affects the transformer's performance and service life. Traditional transformer core welding methods typically rely on manual welding or semi-automatic welding equipment, which presents the following problems:

[0003] Unstable welding quality:

[0004] The quality of manual welding is highly dependent on the operator's skill level and experience, and there can be significant differences in welding quality between different operators.

[0005] Uneven weld seams and welding defects can easily occur during the welding process, affecting the performance of the transformer.

[0006] Low production efficiency:

[0007] Manual welding is slow and cannot meet the needs of large-scale production.

[0008] Although semi-automatic welding equipment has been improved, it still requires manual intervention and has limited production efficiency.

[0009] High labor intensity:

[0010] Prolonged manual welding work places a significant burden on the physical strength and health of operators.

[0011] Operators need to frequently adjust the welding position and angle, which increases the intensity of their work.

[0012] High scrap rate:

[0013] Unstable welding quality easily leads to defective products, increasing production costs.

[0014] Waste disposal and rework further reduce production efficiency.

[0015] Poor security:

[0016] There are safety hazards in manual welding, such as arc burns and inhalation of fumes.

[0017] The equipment lacks effective safety protection measures, making it difficult to guarantee the safety of operators.

[0018] Insufficient cleanliness:

[0019] Before welding, the surface of the iron core often contains impurities and an oxide layer, which can affect the welding quality.

[0020] Traditional equipment lacks an efficient cleaning mechanism, making it impossible to thoroughly clean the surface of the iron core before welding. Utility Model Content
