25mm.The diameter range of second profiled section 5 is 5~10mm, and length range is 25~35mm.
A kind of reduced copper capillary tube or pipe fitting high-efficiency high-accuracy process processing technology, include the following steps: Step 1: first
First, by the fixed clamping of stair-stepping formed punch 1 on full-automatic rotating pipe end machine or other auto-manual rotary punching apparatus；Again will
The component clamping of expander is needed to fix；It is carried out Step 2: passing through peripheral control unit or manually controlling using stair-stepping formed punch 1
The continuous punching of pipe fitting；Step 3: stair-stepping 1 return of formed punch；Step 4: clamping return；Step 5: unloading processed pipe
Part.
The specific process principle of the reduced copper capillary tube or pipe fitting high-efficiency high-accuracy processing tool is as follows:
Firstly, copper pipe is clamped between clamping, using stair-stepping formed punch 1 under ordinary motor drive high speed rotation, watching
It takes after being accurately positioned under motor drives and is pushed into internal diameter of copper pipe along copper pipe centerline direction straight line, copper pipe is in stair-stepping formed punch
Under the action of linear thrust and high-speed rotating twisting resistance, formed punch angular expanse power, force copper metal straight along stair-stepping formed punch
Radial 90 degree of flowings of the line direction of motion, longitudinal (or parallel) 180 degree flowing are flowed with the formed punch conical surface at 60~120 degree, axial
The general flow of 20~45 degree of flowings, copper pipe expansion shorten molding and complete to deform for the first time, and the second of subsequent stair-stepping formed punch 1
Stage carries out continuing to process to the copper pipe of first stage machine-shaping, and Repeated expansion, which shortens molding, to be completed to deform for the second time, and second
Secondary processing processing capacity is the 25~30% of first time, and mainly sizing reaches standard requirements, and the diameter for completing product is small end respectively
3.2~9.52mm processes 4.76~10.5mm of size after the molding of end first stage, 7~12.7mm of size after second stage molding；
Since the Combined machining mode of stair-stepping formed punch 1 makes full use of the good elongation percentage of copper, processing efficiency is greatly improved, it is comprehensive to add
Work amount reaches the 200% of key dimension, while reasonable formed punch angle, drawing velocity, rotation speed determine metal flow direction
With finished product wall thickness thickness, finished product wall thickness economy by reducing 50% originally, and be increased to 30~40%(such as: copper pipe wall thickness is 1mm, former
Wall thickness is 0.5mm after method processing, and existing method is processed as 0.6~0.7mm, and wall thickness, which increases, reduces air-conditioning or refrigeration equipment leakage
Rate), nose of punch, which is angularly processed and is provided with cutting slot, mainly reduces processing resistance, and heat radiation lubricating guarantees copper pipe surface matter
Amount.
Traditional common punch apparatus processing action of same reducer pipe product is completed by 8 steps: the common formed punch punching of mold cramping-
Pressure-return-tooling displacement-common formed punch punching press-return-tooling return-clamping return.
The application only needs 4 step processing actions: mold cramping-stepped punch continuous punching-using the equipment of stair-stepping formed punch 1
Return-clamping return.
In conclusion the application can reduce manufacturing procedure significantly, whole labor intensity is reduced, it is effective to ensure that product expands
The quality of hole machined improves whole production and processing efficiency.
It is above-described, it is merely preferred embodiments of the present invention, but protection scope of the present invention is not limited to
This, anyone skilled in the art in the technical scope disclosed by the present invention, according to the technique and scheme of the present invention
And its inventive concept is subject to equivalent substitution or change, should be covered by the protection scope of the present invention.
