Description

Technical Field

[0001] The invention belongs to the technical field of transformer insulating stays and relates to stay groove cutting processing equipment and a working method thereof. Background Art

[0002] As the main spare parts of transformer insulation, the stay is one of the main insulation parts of transformer windings. It plays the role of interlayer support and insulation, and forms a heat dissipation oil channel. Its cleanliness must ensure that there is no water, oil, metal and other conductors, and there must be no carbonization during the processing. At present, the equipment for processing stays includes: single-strand machine (multi-strand machine), milling and drawing machine, pneumatic cutting saw, bench drill, etc. Its production process is relatively long, among which the processes such as marking, drawing and milling notches, drilling, and deburring occupy a large number of personnel resources. In addition, due to the large number of overall processes, the material transfer time between processes is long, the semi-finished materials occupy a large area, and the production cost is high, which often becomes the main bottleneck of production.

[0003] At present, there is still a lack of specialized production equipment on the market for key processes such as stay milling, cutting, and drilling. Considering that stays are key components for interlayer support and insulation of windings, their demand is huge. The excessive processing steps and long processing cycle under traditional processes make stay processing an important time-consuming point in the transformer production process, which has a significant impact on the overall production efficiency.

Workpiece feeding: The X-axis starts from a remote point and pushes the workpiece to the processing position; 3. Workpiece clamping: The X-axis pushes the workpiece to the processing head position, and the photoelectric switch senses whether there is a product at the workpiece clamping plate 22. If there is a product, the cylinder descends to clamp the product; 4. The workpiece continues to feed in the X-axis direction: The X-axis continues to move forward, and after it is in place, it is pressed and processed. While pushing forward, the cut-off material head is pushed to the waste box 24 (the waste size is less than 190 mm); 5.
