Abstract
The invention discloses a cold-drawing process for an aviation-grade seamless stainless steel tube, which is implemented through the steps of deoiling, solution treatment, raw material pickling, floating cold-rolling, floating cold-drawing and finished product generation. The process is reasonable and easy to use, and the process is an ideal technique for processing the aviation-grade seamless stainless steel tube by way of cold drawing.
Description
Affiliated technical field
The present invention relates to a kind of processing technology of stainless steel tube, particularly a kind of aviation-grade gapless stainless steel tube cold-drawing technology is applicable to the production of aviation-grade gapless stainless steel tube.
Background technology
At present, aviation-grade gapless stainless steel tube production technology is unreasonable, and the product processed inner surface quality is poor, does not satisfy user's requirement.
Summary of the invention
Problem to be solved by this invention is, overcomes the deficiencies in the prior art, and a kind of aviation-grade gapless stainless steel tube cold-drawing technology is provided.This technology is not only reasonable in design, and is easy to use, and save material, and crudy is good.
The technical solution used in the present invention is: deoil, solid molten handle, the pickling raw material → cold rolling → cold-drawn of moving about of moving about → go out finished product.
Prove that through process practice above-mentioned technology is feasible, the product inner surface quality after the drawing is fine, is proved that fully dimensional accuracy is also very high in the enlarging check again, and the deflection of cold-drawn is very big, and the value of practical application is arranged.
Cold-drawn is directly to pull out machine at little tonnage doubly-linked to carry out, and drawing speed is about 8-10m/min, and floating core head cold-drawn equilibrium of forces is effective when pulling out the machine stepless time adjustment.
The floating core head cold-drawn need be controlled each reduction in pass, and lengthening coefficient is between 1.2-1.5.
Lubricant adopts ZF-502C inwall lubricating system.
Because of finished product D/S=10, steel pipe is stable cross section in distortion, can consider on the jar drawbench of garden, to pull out single Zhi Changguan, certainly the tube drawing die holder should be that generatrix direction along the jar face of cylinder, garden can move in stepless time adjustment, during with the assurance draw, pulling capacity (along garden jar tangential direction), that is to say that floating core head pulling pipe should have the not tube drawing round can equipment of usefulness forever perpendicular to the nib end face.In addition, also should be equipped with long tube oil removing and coil pipe brightness heat treatment equipment.
Whether up-to-standard the aviation pipe is, singly do not depend on tube drawing with floating plug and replace the empty sinking tube reducing, also relevant with tube surfaces quality (as pit, pit, scuffing etc.) state in the manufacturing procedure above the tubing, therefore this technology should combine with half-finished quality examination (as the semi-finished product ultrasonic examination), reconditioning, could fundamentally solve the enlarging of aviation pipe finished product, flaw detection qualification rate problem.
The beneficial effects of the utility model are, technology is reasonable, and is easy to use, save material, and crudy is good.
The specific embodiment
Technology is as follows: deoil, solid molten handle, the pickling raw material → cold rolling → cold-drawn of moving about of moving about → go out finished product.
Prove that through process practice above-mentioned technology is feasible, the product inner surface quality after the drawing is fine, is proved that fully dimensional accuracy is also very high in the enlarging check again, and the deflection of cold-drawn is very big, and the value of practical application is arranged.
Cold-drawn is to carry out on 9 meters little tonnage doubly-linked broaching machines, and drawing speed is about 8-10m/min, and floating core head cold-drawn equilibrium of forces is effective when pulling out the machine stepless time adjustment.
Lubricant adopts ZF-502C inwall lubricating system.
Because of finished product D/S=10, steel pipe is stable cross section in distortion, can consider on the jar drawbench of garden, to pull out single Zhi Changguan, certainly the tube drawing die holder should be that generatrix direction along the jar face of cylinder, garden can move in stepless time adjustment, during with the assurance draw, pulling capacity (along garden jar tangential direction), that is to say that floating core head pulling pipe should have the not tube drawing round can equipment of usefulness forever perpendicular to the nib end face.In addition, also should be equipped with long tube oil removing and coil pipe brightness heat treatment equipment.
Whether up-to-standard the aviation pipe is, singly do not depend on tube drawing with floating plug and replace the empty sinking tube reducing, also relevant with tube surfaces quality (as pit, pit, scuffing etc.) state in the manufacturing procedure above the tubing, therefore this technology should combine with half-finished quality examination (as the semi-finished product ultrasonic examination), reconditioning, could fundamentally solve the enlarging of aviation pipe finished product, flaw detection qualification rate problem.
