Description
Technical field
The utility model relates to a kind of cutoff device of long U bending machine, and especially a kind of have a cutoff device that a plurality of cutter head assemblies can cut a plurality of pipe fittings simultaneously, and a plurality of cutter head assemblies of this cutoff device can be regulated separately.
Background technology
Fin-tube type heat exchanger has application widely as a kind of compact heat exchanger at refrigeration industry.Along with the technical development of air-conditioning and refrigeration industry, and the further strict control of environmental regulation, the requirement of heat exchanging unit self heat exchange property is strict more, and is low to remedy the alternative refrigerant performance.Therefore, heat exchanger structure (heat exchanger tube and fin type) and relevant heat exchanger forming technology are the key factors that influences heat exchange property, have great importance for the whole heat exchange property that improves heat exchanger.The forming process of heat exchanger mainly contains following three kinds of forming technologies: canal curvature is shaped (forming the U-shaped pipe), and mechanical expanding is shaped (realizing that pipe-wing connects), tube bank bending and forming (forming L type or G type heat exchanger).
Preceding at curved long U (long U is a kind of U-shaped pipe, has another name called hair fastener pipe or U-shaped long tube), the pipe fitting that needs the cutting preseting length is with blanking.Existing long U bending machine is in order to raise the efficiency, and each blanking has a plurality of pipe fittings to cut (for example 8,12 pipes cutting together) simultaneously, and all cutter head assemblies promote feed by same oil cylinder.Because the cutting blade abrasion degree of each cutter head assembly is also inequality, this just causes the pipe fitting kerf quality to descend, and is prone to waste product.
Summary of the invention
