Description
Technical field
The present invention relates to fin machining devices, and in particular to a kind of plate-fin heat exchanger fin disconnecting device.
Background technology
Fin is the primary element of plate-fin heat exchanger, and diabatic process is mainly completed by fin.In production, fin
Molding machine be for the special equipment by coiled aluminium foil Continuous maching at fin, after fin punch forming, need to according to design ruler
Little progress row is cut off, and fin cut-out efficiency after molding and cut-out quality directly affect manufacturing schedule and product quality.For wave
The fin of high H≤4.7mm, it is most of on present fin molding machine all to carry automatic disconnecting device, however for wave height H ＞
The fin of 4.7mm, current major part Workshop Production are cut off using scissors or wallpaper knife, and not only labor intensity is big, production effect
Rate is low, and is easy rolled edge deformity after cutting out, and influences rear process assembly and quality of vacuum brazing.
Currently, a kind of fin disconnecting device of application number 201610085634, the device is by drive component, fin channels group
Part, fertile nurse counting component and cutter assembly are constituted, and the drive component is connect with cutter assembly, driving cutter assembly movement,
The fin channels component include fin channels, induction fin by photoelectric sensor and control fin stabilization transmission blow

This disconnecting device, upper cutter are fixedly mounted on knife rest, upper cutter between fin at a distance from be not easy to adjust, cause this to cut
Disconnected device only adapts to the fin of low height range, and cutoff action is risen by lower cutter and forms shearing force with upper cutter, to complete
The cutoff action of fin；In cutting-off process, upper cutter does not resist fin, after lower cutter rising supports fin so that on
Cutter touches fin and cuts off fin with lower cutter collective effect, and it is inclined that fin rising can so that scheduled off-position occurs
It moves, the notch of every section of fin is caused to differ, and run-off the straight can cause notch run-off the straight when fin rising, both knots
When fruit can all cause the later stage to assemble strip of paper used for sealing, strip of paper used for sealing is easily pressed in the trimming of fin incision, influences heat exchanger leakproofness；In addition,
Since upper cutter and fin channels bottom surface relative distance are smaller, the fin specific aim of the disconnecting device certain altitude is stronger but right
The adaptability of different height fin is poor.
