Abstract
The invention discloses a process for processing a capillary and relates to a method for processing a capillary. The process comprises the following steps: adopting a SUS304 stainless steel band as blank, rolling the blank into pipes and then welding into a pipe blank; placing a core head into the pipe blank; setting a coil pipe pressure detection cleaning and annealing procedure between wall reduction drawing and diameter reduction drawing operation and forming wall reduction drawing and diameter reduction drawing operation carried out forward and backward by a hammering machine, a drawing machine and a die; carrying out degressive diameter drawing operation and then carrying out coil pipe pressure detection cleaning; finally fine finishing and packaging to enter a warehouse. The invention replaces rolling with a welding process, prevents various metal materials with different quality from entering the capillary, improves the quality of a product, carries out coil pipe pressure detection after each wall reduction and diameter reduction drawing operation, so as to discover the defects of the capillary in the process of production in time and correct in time, thereby improving theyield of the product.
Description
Technical field
The present invention relates to a kind of capillary processing method.
Background technology
Capillaceous being of wide application, be commonly used for throttling arrangement, as be used in refrigerator, form low pressure liquid on the air-conditioning and supply with evaporimeter, after generally being rolled into blank pipe, capillary production now carries out subsequent treatment again, because milling train is rolling different metal material often, rolled lubricating oil also can not often be changed, in the operation of rolling, easily different metal material is sneaked into pipe, influence quality capillaceous and might enter pipe inside, cause the scuffing of pipe, yield rate reduces, and generally only just carry out Mechanics Performance Testings such as pressure in the capillary production now when pipe is shaped to preliminary dimension, and the pipe shaping is difficult to once generally be shaped, this disposable detection can not in time be found the defective of pipe and be revised, yield rate is reduced, improved the production cost of enterprise.
Summary of the invention
The present invention is directed to above-mentioned defective, purpose is to provide a kind of capillary processing technology that can improve the capillary quality of production.
Technical scheme of the present invention is: the present invention is a blank with the SUS304 stainless strip, blank is rolled into tubulose after be welded into pipe, again core print is put into pipe, by subtract before and after swaging-machine, stretching-machine and the mould that wall stretches and the tube reducing stretched operation subtracts to being shaped that wall stretches and the tube reducing stretched operation between establish the coil pipe pressure detecting and clean and annealing operation, behind the tube reducing stretched operation, carry out the coil pipe pressure detecting once more and clean, finishing tough reason and packing warehouse-in.
The invention has the beneficial effects as follows: replace rolling with welding procedure, avoided various inhomogeneous metal materials to sneak in the capillary, improve the quality of products, the present invention simultaneously carries out the coil pipe pressure detecting at every turn after subtracting wall tube reducing stretched operation, so that can in time find the defective in the capillary production process, and can make correction timely, improve the finished product rate.
The specific embodiment
The present invention is a blank with the SUS304 stainless strip, blank is rolled into tubulose after be welded into pipe, again core print is put into pipe, by subtract before and after swaging-machine, stretching-machine and the mould that wall stretches and the tube reducing stretched operation subtracts to being shaped that wall stretches and the tube reducing stretched operation between establish the coil pipe pressure detecting and clean and annealing operation, behind the tube reducing stretched operation, carry out the coil pipe pressure detecting once more and clean, finishing tough reason and packing warehouse-in.
Concrete, processing process of the present invention is as follows:
1) selection: choosing the SUS304 stainless strip is blank, and it is carried out composition, mechanical property detection, makes it to meet production requirement;
2) welded tube: clean band with trichloro-ethylene earlier, be rolled into tubulose by make-up machine then, be welded into pipe by welded tube mill again;
3) subtracting wall stretches: inject lubricating oil in the pipe and also put into core print, put it in the mould, by swaging-machine, stretching-machine through repeatedly subtracting wall to size;
Whether 4) the coil pipe pressure detecting is cleaned: will charge into the air of certain pressure in the pipe, and it is immersed in trichloro-ethylene liquid, detect and leak gas, then eliminate as gas leakage, when detecting pipe rocked in trichloro-ethylene liquid and clean;
5) annealing: utilize annealing furnace under the atmosphere of decomposed ammonia, pipe to be carried out annealing in process;
6) tube reducing stretches: by stretching-machine, forge thin mould and mould and be formed into size by tube reducing repeatedly;
7) secondary coil pipe pressure detects cleaning clearly: as 4) the step operation;
8) carry out finishing and packing warehouse-in.
Claims (1)
1, a kind of capillary processing technology, with the SUS304 stainless strip is blank, it is characterized in that: blank is rolled into tubulose after be welded into pipe, again core print is put into pipe, by subtract before and after swaging-machine, stretching-machine and the mould that wall stretches and the tube reducing stretched operation subtracts to being shaped that wall stretches and the tube reducing stretched operation between establish the coil pipe pressure detecting and clean and annealing operation, behind the tube reducing stretched operation, carry out the coil pipe pressure detecting once more and clean, finishing tough reason and packing warehouse-in.
