Abstract
The invention discloses an outward flanging device for a flanged hole of a tube wall of a metal thin tube. An implementation method of the device is that: a corresponding hole is formed on a fixed die; a hole flanging movable core with a around ball is arranged in the hole; a flanged hole is formed on a hole flanging female die; a pushing nail, a pushing spring and a screw are arranged in the hole; when a workpiece is sleeved in the fixed die, the hole flanging female die and a pressing block are pushed by a cylinder to slide in a T-shaped groove pedestal; after the workpiece is pressed, the upper die with the round ball is descended, and a spherical surface of the hole flanging movable core ball is pushed by the spherical surface of the upper die to project, so that the aim of flanging the hole outwards of the copper tube is fulfilled. According to the device, internal resistance caused by inward flanging of the conventional pipeline is eliminated, reactive power consumption of a compressor is reduced, and the efficiency of the compressor is increased.
Description
Affiliated technical field
The invention belongs to metal cold-working processing technique field, relate to turning-up devices outside a kind of metal foil tube wall hole.
Background technology
At present, the hole flanging on the common thin-wall metal tube wall is the forward hole flanging, promptly to the pipe in-flanges.Because the flange part is in the inside of metal tube, so the piping that special requirement is arranged is brought influence.As gathering of air-condition heat exchanger managing piping because turn in being in the flange hole, directly the interior refrigerating fluid of influence pipe is mobile.Influence the Energy Efficiency Ratio of air-conditioner, adopt the outer turning-up devices of metal tube pipe tap, after relevant piping connected, gas and liquid was mobile unimpeded in the pipe, and the resistance of ducting is little.
Summary of the invention
Turn over gas and the not smooth problem of liquid flow in the pipe that brings in the metal foil tube wall hole in order to overcome; The present invention provides a kind of brand-new device; Hole flanging on the multiple metal foil tube wall of this device processing is for turning up, and the pipeline after the connection has been eliminated the internal resistance that causes with the preceding pipeline in-flanges.
The present invention's scheme that is adopted of dealing with problems is: the corresponding hole of processing on cover half, load onto the hole flanging dnockout core of band garden ball, processing flange hole on the hole flanging die in the hole; Cover half is fixed on the T type bottom land seat, and the hole flanging dnockout core is contained in the hole of cover half, and the T type groove on hole flanging die, the binder block is slidingly matched with T type bottom land seat respectively; In the hole of the correspondence that pusher is followed closely, the pusher spring is successively packed the hole flanging die into, use screw-driving, when workpiece is inserted in the cover half; Cylinder promotes the hole flanging die, binder block slides in T type bottom land seat, and behind the workpiece pressing, the patrix of band ball descends; The patrix sphere promotes hole flanging dnockout core sphere and outwards ejects, and realizes the purpose of the outside hole flanging of copper pipe.
The invention has the beneficial effects as follows; Operating personnel put into cover half with workpiece, and hand is pressed the cylinder button, after patrix descends; Can accomplish the hole outward flanging on the metal foil tube wall; This device has been eliminated the internal resistance that causes with the preceding pipeline in-flanges, has reduced the idle power consumption of compressor, has improved the efficient of compressor.
