Problems solved by technology

At present, the flat tube cutting device commonly used in industry adopts the combination of knife cutting and pulling off. The knife cutting will exert a relatively large pressure on the flat tube, causing the end surface of the flat tube to shrink, which will hinder the flow of refrigerant and reduce the replacement rate. The heat exchange efficiency of the heater, while the breaking process needs to be realized by the reciprocating motion of the fixture, which restricts the production efficiency

Abstract

The invention provides a device for cutting off a flat tube of a heat exchanger, which comprises a machine base, a milling mechanism capable of transversely sliding along the machine base and a die-cutting mechanism capable of longitudinally sliding along the machine base, wherein the flat tube which is longitudinally conveyed along the machine base is arranged in the milling mechanism and the die-cutting mechanism by penetration, a milling cutter for milling the flat tube and forming a milling cut is arranged on the milling mechanism, and a die cutter which can detect the position of the milling cut and perform die-cutting is arranged on the die-cutting mechanism. The device has the advantages that the device for cutting off the flat tube of the heat exchanger can avoid the deformation and the shrinkage of the cut-off end surfaces of the flat tube, lead the flow of refrigerant to be smooth and improve the heat exchange efficiency of the heat exchanger.

Description

technical field [0001] The invention relates to a flat tube cutting device for a heat exchanger. Background technique [0002] In order to improve the heat transfer efficiency of air-cooled heat exchangers, automotive air-conditioning heat exchangers have been developed from traditional tube-fin and tube-belt types to parallel-flow types. The parallel flow heat exchanger consists of flat tubes, headers and fins. The flat tube is the carrier of the refrigerant and has a direct impact on the performance of the heat exchanger. The flat tube is usually an aluminum tube body with a separator inside. The flat tube is usually rolled into a coil and shipped from the factory. Therefore, the heat exchanger manufacturer needs to straighten and cut the flat tube before use. At present, the flat tube cutting device commonly used in industry adopts the combination of knife cutting and pulling off. The knife cutting will exert a relatively large pressure on the flat tube, causing the end...
