Description

Quick splicing device of rectangular flange for fan

Technical Field

The utility model belongs to the technical field of flange processing equipment, and particularly relates to a rectangular flange rapid splicing device for a fan.

Background

Pipes are widely used in the field of ventilation transportation, but flanges for pipe connection are varied. Taking a rectangular flange as an example, most of the flanges are spliced into rectangular flanges by angle steel or steel plates, and then connecting holes are drilled through scribing or drilling jig. Because the fan inlet box and the fan outlet are both rectangular flanges, the rectangular flanges are also designed for the convenience of space arrangement of the ventilating duct. However, the splicing and drilling of the rectangular flange are quite labor-consuming, and the phenomenon of uneven flange surfaces can also occur, namely, two butt-joint flanges are affected by uneven contact surfaces, and the defect of leakage is easy to occur.

Specifically, the laser blanking device is convenient to integrally cut the small flange, the drilling of the connecting holes is accurate, and the plate is not wasted. However, the flange with larger size cannot adopt an integral laser cutting mode due to material utilization cost, but needs to be cut into four frames respectively for the whole plate, then splice welded into a whole, and finally the connecting hole is drilled, so that the purpose of saving the plate can be realized. However, when four frames are spliced, errors are easy to occur, and the situation that the planes of the frames do not correspond to each other and the butt joint angles are deviated is caused, so that the flatness of the planes of the butt joint of the flanges and the drilling precision of the connecting holes are affected.
