Description
Technical field
The utility model relates to the assembling device of automobile pipeline, specifically is a kind of tube wall boring hemmer that long size pipeline patches mutually that is used for.
Background technology
In the automobile pipeline is produced, to two long sizes (size be approximately 300～1200mm) pipelines patch employing mutually be: in bassoon, bore spliced eye, implement to add a stiffener after the welding in the hole of tubule insertion bassoon, purpose prevents the crooked weld bond cracking that causes of tubule exactly, strengthens the fastness that tubule is connected with bassoon.Its shortcoming is: big tube wall is only holed and can not flange, must strengthen fastness by stiffener, and complex process, splicing position multiple welding influence the mechanical performance of tubing, have reduced the service life of pipe fitting.
At present, the utility model that a name is called " a kind of tube wall boring hemmer " is disclosed on the website of State Intellectual Property Office, this device improves above-mentioned processing mode, hole hemmer in drilling bassoon spliced eye by tube wall, the edge of the mouth of pipe can be dug from inside to outside a circle tubulose mouth, the tubulose mouth of digging can clad the outer wall at the tubule that inserts, can play the stable effect of clamping tubule like this, guarantee the rigidity that two pipes are pegged graft, reduce the number of times of welding simultaneously, improve the mechanical performance of material.This device is particularly useful for the processing (short size, bigbore pipe can be realized piercing and flanging with mould) of long size pipe, the processing technology of saving stiffener, and overall quality level increases.But still there is following shortcoming in this tube wall boring hemmer:
1, because two flange cuttves that are used for flange is to drive by the helicla flute that bores cutter to stretch out, shrink by flange cutter afterbody corresponding spring, and the flange cutter is the tubulose mouth that is used to process bassoon, so driving poor reliability of this flange cutter, and use spring also can't use because of elastic failure makes device easily for a long time, i.e. poor stability.
2, owing to device is mounted in the stage casing of boring cutter, promptly whole device supports by boring cutter, drives whole device by the rotation of boring cutter, and long-term so stressed use makes the distortion of brill cutter easily and can't process.
3, central revolving part should rotate synchronously with the brill cutter, can make the telescopic moving in boring the cutter helicla flute of flange cutter, and central revolving part and brill cutter fixedly is very loaded down with trivial details technology, and, along with the grinding of the boring cutter central revolving part that shortens will be made corresponding adjustment with the fixed position of boring cutter, this is to be difficult to realize.
4, because general brill cutter helicla flute lift angle is 60 °, in order to obtain 40 °～45 ° of desirable helicla flute lift angles, must customization bore cutter, cost is too high like this.
The utility model content
The technical problems to be solved in the utility model is, provide a kind of flange cutter driving good reliability, good stability, be difficult for making and bore cutter distortion, fixing simple, tube wall boring hemmer that cost is low.
The technical solution of the utility model is, a kind of tube wall boring hemmer with following structure is provided, and comprises the brill cutter that is used to hole, two flange cutter, chucks that are used for flange; It also comprises the linear telescopic reciprocator on the machine that can be installed to rotating, described brill cutter is provided with can be for two flexible through holes of the flange cutter that intersects, be provided with fixing traveller in the described chuck with linear telescopic reciprocator, also be fixed with on the described traveller and can drive the interior propelling fork of through hole that two flange cuttves stretch out the through hole that bores cutter synchronously or are retracted to the brill cutter, one end of described brill cutter and chuck is fixed, and the other end of described linear telescopic reciprocator and chuck is fixed.
After adopting above structure, the utility model compared with prior art has the following advantages:
1, because two flange cuttves is cross-distribution, and stretch out or shrink by advancing fork to drive the flange cutter, and advance the fixing traveller of fork and linear telescopic reciprocator to fix, just drive two flange cuttves by propulsion cylinder, advance distance is big, the driving good reliability of this flange cutter, and the stability of propulsion cylinder also to compare spring good.
2, owing to bore the bottom that cutter only is mounted in device, the integral body by linear telescopic reciprocator drives that to bore swivel moving, and long-term so stressed use is difficult for making bores the cutter distortion and can't process.
3, owing to an end of described brill cutter and chuck is fixed, do not influence when boring the cutter wearing and tearing and bore the fixing of cutter and central revolving part, make brill cutter and central revolving part fixing simple
4, owing to when the variation in processed aperture, only need to change to bore cutter and flange cutter, need not to customize special-purpose brill cutter, cost is low like this.
