Abstract

The invention provides a ventilating duct connecting port and a ventilating duct connecting port cold rolling mill. The ventilating duct connecting port comprises a first U-shaped groove, a second U-shaped groove and an L-shaped connecting beam, wherein the first U-shaped groove and the second U-shaped groove are of U-shaped structures and are connected with each other, the opening direction of the first U-shaped groove is opposite to the opening direction of the second U-shaped groove; and the ventilating duct connecting port cold rolling mill comprises twelve groups of cold rolling wheel sets, and according to the sequence from the first cold rolling wheel set to the twelfth cold rolling wheel set, a cold-rolled plate is subjected to cold rolling and is formed into the ventilating duct connecting port, thus the machining process is reduced, and the machining efficiency is improved.

Description

technical field [0001] The invention relates to the field of mechanical equipment, in particular to an air channel interface and an air channel interface cold rolling mill. Background technique [0002] At present, central air-conditioning and indoor fresh air systems have penetrated into people's daily life. However, central air-conditioning and indoor fresh air systems require warm / cold air ducts for indoor and outdoor ventilation and ventilation. The air ducts usually extend from indoors to outdoors, so The air duct interface is required to connect external devices. [0003] In the prior art, the airway interface is L-shaped, and is fixedly connected to the airway plate through bolt connection, which may cause stress concentration at the joint between the airway interface and the airway plate, and the decrease in the strength of the airway interface caused by the disturbance of the airway. . [0004] In addition, the existing air duct interface is generally formed by ca...
