Abstract
A metal tube seal process mainly resolves the problem that machining stainless steel tubes with large diameters wastes time and energy and is difficult to seal with the existing seal method of a metal pipe fitting port. The metal tube seal process is characterized by including the following process steps: a installing a metal tube (1) in clamping mode in an elastic clamping sleeve capable of rotating on a machine tool; b utilizing a no-cutting-edge tool (3) to extrude a port of the metal tube (1) in high rotation, extruding the port towards the center in the radial direction while moving outwards the no-cutting-edge tool (3) in the axial direction, forming a conical surface and then extruding the conical surface in the axial direction until the port of the metal tube (1) is completely sealed and integrated at a high temperature in melting mode; c utilizing a turning tool to machine the outer end face of the sealed port of the metal tube (1) to be flat. The metal tube seal process changes the previous machining method, achieves sealing the stainless steel tubes with large diameters, saves time and labor, and is simple in working procedures, low in cost, high in machining efficiency and flat and smooth in appearance.
Description
Technical field
The present invention relates to a kind of mouth-sealing method of metal tube port, be specifically related to a kind of metal tube sealing process.
Background technology
When producing five metals suspension member (hereinafter to be referred as suspension member),, need seal processing to the port of metal tube for serviceability and requirement such as attractive in appearance.The metal that the material of suspension member generally adopts copper, stainless steel, aluminium alloy, kirsite etc. to be difficult for getting rusty in order to improve working (machining) efficiency, generally is that the port to metal tube seals on instrument lathe.Utilize fricative heat between metal tube and the no angle of throat tool to make the port of metal tube softening; Extruding makes the port of metal tube distortion fuses into blind end at last to the center to the port of metal tube through no angle of throat tool simultaneously; For the soft metal (like copper, aluminium alloy, kirsite etc.) of minor diameter, this processing method obviously is feasible.When the customer requirements metal tube used the big slightly stainless steel material of pipe diameter, because stainless steel material hardness is higher, caliber was bigger simultaneously, directly advances cutter to seal to tube hub, wastes time and energy, and seals difficulty.
Summary of the invention
In order to overcome disadvantages of background technology, the present invention provides a kind of metal tube sealing process, wastes time and energy, seals the problem of difficulty when mainly having solved the big slightly stainless steel tube of the mouth-sealing method processing diameter of existing metal tube port; This metal tube sealing process has changed processing method in the past, has realized the big slightly stainless steel tube of diameter is sealed, and is time saving and energy saving; Operation is simple; Cost is low, and working (machining) efficiency is high, and flat appearance is smooth.
Technical scheme of the present invention is: this metal tube sealing process step is following:
In the elastic jacket that a. the metal tube clamping can be rotated on lathe;
B. adopt the no angle of throat tool that has front end compressive plane and side compressive plane; The metal tube that utilizes the front end compressive plane of no angle of throat tool to rotate at a high speed to metal tube center radial compression; Meanwhile move axially no angle of throat tool to the outer end of the port of metal tube; It is softening that fricative heat makes the port of metal tube between metal tube and the no angle of throat tool, and the port of metal tube forms taper seat to its center distortion gradually; Utilize the side compressive plane of no angle of throat tool to rely on the conical end of metal tube, slowly inwardly extruding, up to the port complete closed of metal tube and at high temperature fuse into one, taper seat is squeezed into the port plane;
C. utilize lathe tool that the outer face processing of metal tube closed port is smooth.
Described machine adopted instrument lathe.
Front end compressive plane on the described no angle of throat tool is an arc surface, and the side compressive plane is the plane.
The present invention has following beneficial effect: owing to take such scheme, utilize that fricative heat softens the port of metal tube between metal tube and the no angle of throat tool, the formation taper seat; Through the side compressive plane on the no angle of throat tool taper seat of metal tube being compressed axially the taper seat that makes metal tube simultaneously piles up and fuses into blind end at last; Adopt lathe that clamping of metal tube is accomplished and seal, realized the big slightly stainless steel tube of diameter is sealed, time saving and energy saving; Operation is simple; Cost is low, and working (machining) efficiency is high, and flat appearance is smooth.
Description of drawings
Accompanying drawing 1 is an initial manufacture view of the present invention.
