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 sealing process of metal tube port.
Background technology
When producing bathroom 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; During to the pipe fitting port sealing in the suspension member, generally be the method that adopts welding, utilize end socket to get lodged in the port of pipe fitting; Polish after the welding, polish; There is following defective in this method: 1. welding the time needs auxiliary material such as welding wire or welding rod, scaling powder, oxygen, liquefied gas, and cost is higher, and also need polish after the welding, operation such as polishing; Operation is loaded down with trivial details, complicated, and working (machining) efficiency is low.2. because welded junction part is prone to defectives such as sand holes, pin hole, influence the attractive in appearance of suspension member, cause the qualification rate of suspension member low.
Summary of the invention
In order to overcome disadvantages of background technology, the present invention provides a kind of sealing process of metal tube port, has mainly solved the low and low problem of qualification rate of mouth-sealing method working (machining) efficiency of existing metal tube port; The sealing process of this metal tube port adopts lathe that frock of metal tube port is accomplished and seals, and operation is simple, and cost is low; Working (machining) efficiency is high; No weld seam, flat appearance is smooth, and qualification rate is high.
Technical scheme of the present invention is: the sealing process step of this metal tube port is following:
In the elastic jacket that a. the metal tube clamping can be rotated on lathe, stretch into a keeper in the elastic jacket, metal tube is enclosed within outside the keeper, the end face of keeper in metal tube and and the end face of metal tube between certain distance is arranged;
B. adopt the end to have the no angle of throat tool of compressive plane; Described compressive plane can make the port of metal tube gradually to its center distortion; Utilize the no angle of throat tool extruding port of the metal tube of rotation at a high speed, it is softening that fricative heat makes the port of metal tube between the port of metal tube and the no angle of throat tool, and the port of metal tube slowly draws in to the center; Radially extend along metal tube after running into keeper at position after the distortion, up to the port complete closed of metal tube and at high temperature fuse into one;
C. utilize lathe tool that the outer face processing of metal tube closed port is smooth.
Further, described machine adopted instrument lathe.
Further, the compressive plane on the described no angle of throat tool is inclined-plane or arcwall face.
Further, described keeper is a pipe shape or cylindric.
Further, described keeper is provided with chamfering.
The present invention has following beneficial effect: owing to take such scheme, utilize that fricative heat makes the port of metal tube softening between metal tube and the no angle of throat tool, through no angle of throat tool the port of metal tube is pushed the port that makes metal tube simultaneously and be out of shape to the center and fuse into blind end at last; Adopt lathe that clamping of port of metal tube is accomplished and seal, operation is simple, and cost is low; Working (machining) efficiency is high; No weld seam, flat appearance is smooth, and qualification rate is high.
Description of drawings
Accompanying drawing 1 is an initial manufacture view of the present invention.
Accompanying drawing 2 is machining state sketch mapes that the port closed of metal tube 1 of the present invention is shaped.
1-metal tube among the figure, 2-keeper, 3-do not have the angle of throat tool, the 4-compressive plane.
The specific embodiment
Below in conjunction with accompanying drawing the present invention is described further:
Combined shown in Figure 2ly by Fig. 1, the sealing process step of this metal tube port is following:
In the elastic jacket that a. metal tube 1 clamping can be rotated on lathe, stretch into a keeper 2 in the elastic jacket, metal tube 1 is enclosed within outside the keeper 2, the end face of keeper 2 in metal tube 1 and and the end face of metal tube 1 between certain distance is arranged;
B. adopt the end to have the no angle of throat tool 3 of compressive plane 4; Described compressive plane 4 can make the port of metal tube 1 gradually to its center distortion; Utilize the no angle of throat tool 3 extruding port of the metal tube 1 of rotation at a high speed; It is softening that fricative heat makes the port of metal tube 1 between the port of metal tube 1 and the no angle of throat tool 3; The port of metal tube 1 slowly draws in to the center, and the position after the distortion is run into keeper 2 backs and radially extended along metal tube 1, also at high temperature fuses into one up to the port complete closed of metal tube 1; Because the existence of keeper 2 is arranged; Port at metal tube 1 can form enough thickness; The turning surplus of sealing the outer face of car flat metal pipe 1 in the road face work operation under guaranteeing; This thickness is by the distance decision between the end face of the end face of keeper 2 and metal tube 1, adjusts through regulating the length that keeper 2 stretches in the metal tube 1.
C. utilize lathe tool that the outer face processing of metal tube closed port is smooth.
The material of the metal tube 1 of the present invention's processing generally is that hardness is lower, the extension property preferred metal, like copper, aluminium alloy, kirsite etc., is not suitable for the pipe fitting that workhardness is higher, the metal material of extension property difference is made.It is softening that fricative heat makes the port of metal tube 1 between this technology utilization metal tube 1 and the no angle of throat tool 3, and the port extruding through 3 pairs of metal tubes 1 of no angle of throat tool simultaneously makes the port of metal tube 1, and distortion fuses into blind end at last to the center, adopts lathe that a clamping completion of port of metal tube 1 is sealed; Operation is simple; Cost is low, and working (machining) efficiency is high, no weld seam; Flat appearance is smooth, and qualification rate is high.It should be noted that in such scheme as not adopting keeper 2, though also can be the port sealing of metal tube 1; But the blind end thickness of the port of metal tube 1 extruding is difficult to control; The turning surplus does not wait when face work, and the workpiece blind end that has is thinner, is difficult to the car planar end surface; Cause workpiece to scrap, product quality is not easy to guarantee.
Described machine adopted instrument lathe.Instrument lathe is simple in structure, and is easy to operate, and working (machining) efficiency is high.
Combined shown in Figure 2ly by Fig. 1, the compressive plane 4 on the described no angle of throat tool 3 is inclined-plane or arcwall face.The gradient of compressive plane 4 or the radian of arcwall face are confirmed by the external diameter of metal tube 1 and the thickness of required blind end.
Combined shown in Figure 2ly by Fig. 1, described keeper 2 is a pipe shape or cylindric.The port that keeper 2 has limited metal tube 1 is extruded the bearing of trend of distortion, can control the thickness of the port sealing rear enclosed end of metal tube 1.When keeper 2 was the pipe shape, the inwall of the blind end of metal tube 1 had convexity, and the intensity of blind end is better, also was beneficial to and sealed fusion, and the fusion time is short; When keeper 2 was cylindric, the inwall of the blind end of metal tube 1 was smooth, and the intensity of blind end is general, and it is long slightly to seal the fusion time.The shape of keeper 2 can be chosen according to actual needs.
Combined shown in Figure 2ly by Fig. 1, described keeper 2 is provided with chamfering.When extrusion metal pipe 1, the sidewall of metal tube 1 is out of shape along the center of the chamfering on the keeper 2 to metal tube 1.Chamfer design is a circular arc, makes the sidewall of metal tube 1 can form rounding off to blind end, has intensity preferably between the sidewall of metal tube 1 and the blind end.
