Change or mecystasis, are covered by stainless steel wire spring in the tube wall of semi-finished product tube body 1.
Step 5, it is cooling: after weld job, using compression cold air from after welding 1 surface of semi-finished product tube body and
It is blown on pressing mold 3, is down to semi-finished product tube body 1 and 3 temperature of pressing mold between 25 DEG C -45 DEG C, open pressing mold 3,
Semi-finished product tube body 1 both ends of the conductive electrode 2 after welding will be welded to remove, the semi-finished product after taking out welding in pressing mold 3
Tube body 1；Cooling effect is to ensure the stability of welding, and prevent scald operator.
Welding quality test: step 6 carries out quality testing to the semi-finished product tube body 1 after welding, by Welding quality test
Semi-finished product tube body 1 after qualification is placed on storage in transfer storage tank, completes golden plastic welding and connects wire reinforced trachea cannula tube body
Production.
Self-test is carried out after the completion of each step, is transferred to next step for examining qualified product to be put into transferring box, is not conformed to
Lattice product are put into recycling bins.
Gold plastic welding of the present invention connects all steps of manufacture craft of wire reinforced trachea cannula in cleaning shop
Interior operation is implemented to complete, and meets the requirement of medical instrument production environment, the reinforced tracheae made using manufacture craft of the invention
Intubation various functions and performance meet clinical use demand.
Embodiment 2
As depicted in figs. 1 and 2, a kind of golden plastic welding of the invention connects the manufacture craft of wire reinforced trachea cannula, the system
Make technique following steps:
Step 1 is cut: the trachea cannula tube body after extrusion molding is assembled on the automatic feed mechanism of automatic cutter, if
Surely start guillotine after cutting parameter, tube body is cut to standard specification to the semi-finished product tube body for requiring length, cuts parameter setting
Are as follows: cutoff length 36CM, speed of cut 1m/s.
Step 2 assembles stainless steel wire spring: the both ends of semi-finished product tube body being connected gas-charging connection, pass through gas-charging connection
The pressure-air that pressure is 0.4-0.6MPa is filled with into semifinished tube body, the dwell time is 1 second, makes the internal diameter of semi-finished product tube body
Expansion increases (internal diameter of semi-finished product tube body generally at least increases 1mm), then wears stainless steel wire spring and send to semifinished tube
The inside of body, shake semi-finished product tube body are in stainless steel wire spring smoothly to flick state naturally, and make stainless steel steel wire
Spring is located at semi-finished product tube body along axial middle position, after placing 2 minutes naturally, up to semi-finished product tube body natural shrinking to original
Beginning internal diameter compresses stainless steel wire spring.
The effect for being passed through pressure-air is to increase the expansion of semi-finished product internal diameter of tube body, facilitates to wear stainless steel wire spring and send
To tubular body.
Step 3, preparation before welding: setting the welding parameter of welding equipment, by the conductive electricity of welding on welding equipment
Pole 2 is contacted with the both ends terminal point of stainless steel wire spring, and the semi-finished product tube body 1 for being equipped with stainless steel wire spring is installed
It is molded in pressing mold 3 and by pressing mold 3.
The welding equipment include a welding controller 4 and a single-phase isolating transformer 5, welding controller 4 with
Single-phase isolating transformer 5 connects, and the welding conductive electrode 2 is installed on single-phase isolating transformer 5, welds the work of conductive electrode 2
With being energy of a charge to be transferred on stainless steel wire spring to increase its surface temperature moment, form hot weld junction.Setting weldering
The welding parameter for connecing equipment sets the execution parameter of welding controller 4, and the ginseng of heating prewelding is first set on welding controller 4
Number are as follows: the time is 2 seconds, welding current 1.1A.
Pressing mold 3 includes upper die and lower die, is provided with the groove structure for being adapted to semi-finished product tube body 1 in upper mold and lower die,
The clamping pressure of pressing mold 3 is 15N.The effect of pressing mold 3 is the inner wall and stainless steel wire spring for making semi-finished product tube body 1
It is contiguously stronger close, keep welding surface more uniform consistent.
Step 4, golden plastic welding connect: starting welding equipment, first carry out heating prewelding, and the heating prewelding time is 2 seconds, welding electricity
Stream is 1.1A, and 1 temperature of semi-finished product tube body for being equipped with stainless steel wire spring is risen to 65 DEG C -80 DEG C, makes postorder welding quality
It is more stable；Firm weldering is carried out after heating prewelding, i.e., welding parameter is adjusted to welding current after heating prewelding is
2.2A is carried out continuously 3 welding, and each weld interval is 2 seconds, makes the semi-finished product tube body 1 for being equipped with stainless steel wire spring
Welding equipment is closed after the completion with being combined together for stainless steel wire spring close and firm, terminates weld job；
The effect of heating prewelding is that 1 temperature of semi-finished product tube body for being equipped with stainless steel wire spring is risen to 65 DEG C -80 DEG C, is generated
It is more stable to weld quality for preliminary solder bond face after guarantee.The high temperature generated when heating prewelding makes to be adsorbed on semi-finished product tube body 1(modeling
Material) surface moisture or other microcosmic particles be discharged, clean solder bond face more, improve welding quality.
The mechanism of firm weldering are as follows: using welding conductive electrode 2 by energy of a charge be transferred to stainless steel wire spring with
The position that semi-finished product tube body 1 is contacted with stainless steel wire spring is worked into molten by the contact surface and adjacent domain of semi-finished product tube body 1
Change or mecystasis, are covered by stainless steel wire spring in the tube wall of semi-finished product tube body 1.
It is carried out continuously 3 welding when firm weldering and carries out the welding that a length of 2 seconds total durations are 6 seconds when single incessantly,
