Straightening mechanism and flat pipe cutting device

Abstract

The invention relates to the technical field of aluminum flat pipe production equipment and discloses a straightening mechanism and a flat pipe cutting device. The straightening mechanism comprises afirst rolling wheel, a second rolling wheel and a detecting assembly, wherein the first rolling wheel is rotationally connected to a first support; the second rolling wheel is rotationally connected to a supporting assembly, and the supporting assembly is connected to a second support in a sliding manner; and the detecting assembly comprises a balancing weight, a tooth belt and an encoder, one endof the tooth belt is connected with the supporting assembly, and the other end of the tooth belt winds around the encoder to be connected with the balancing weight. The straightening mechanism is arranged between an uncoiler and a cut-off machine, a flat pipe is conveyed through the first rolling wheel and the second rolling wheel, the flat pipe is pulled to be straight after passing through thefirst rolling wheel and the second rolling wheel, and the size of the cut flat pipe meets the requirement. The tension change on the second rolling wheel is detected through the detecting mechanism, when the diameter of a material roll on the uncoiler is reduced, by adjusting the rotation speed of the uncoiler and the cut-off machine, the tension of the flat pipe is kept balanced, and stable feeding is achieved.

Description

technical field [0001] The invention relates to the technical field of aluminum flat tube production equipment, in particular to a straightening mechanism and a flat tube cutting device. Background technique [0002] The parallel flow heat exchanger is composed of flat tubes, headers and fins. The flat tubes are the carrier of the refrigerant and have a direct impact on the performance of the heat exchanger. Flat tubes are usually aluminum tubes, which are often rolled into discs before leaving the factory. Therefore, heat exchanger manufacturers need to fix the disc-shaped flat tubes on the uncoiler before use, and then use the uncoiler to feed the material, and the cutting machine cutting. In the prior art, when cutting flat tubes, in order to ensure that the size of the cut flat tubes meets the requirements, a straightening mechanism is often provided between the uncoiler and the cutting machine, but as the diameter of the flat tube coil decreases, The speed of the unco...
