Abstract
The invention is an engine oil suction filter soldering assembly method, which uses traditional pressing technics forming or rivet pressing technics to produce a flange plate (1), a supporting piece (3) and a filtering net (4), use a weld seam pipe to produce an oil pipe (2) by the tube sinking forming technics, then arrange the flange plate (1) and the filtering net (4) at the two ends of the oil pipe (2), the supporting plate (3) the outer wall of the oil pipe 2 close to the filtering net 2, then, lay the installed engine oil suction filter in an air protecting braze welding furnace stably to proceed braze welding in furnace. By the method in the invention, the prepared product not only has good and appearance and quality, even welding line, fixed welding, and is beautiful, but also doesn't need galvanizing, which prevents after effect of the zinc layer peeling off and improves the whole quality of the product.
Description
Technical field
The present invention relates to a kind of assembly method of sump strainer, specifically, is the method that a kind of sump strainer adopts the soldering assembling.
Background technology
At present, the welding processing of sump strainer, what mainly adopt is traditional welding processing, as CO2 gas shielded arc welding, manual electric arc welding etc.These welding methods are all by operator's technical merit and qualification and artificial control.The uniformity of its welding is poor, and the welding slit is big, and weld seam is inhomogeneous, and overlap is piled up back influence assembling and needed polishing; Easily the oil pipe burn-through is not reached the air-tightness requirement; Weld seam is rough and uneven in surface, not of uniform size causing and influence outward appearance; The uniformity of weld strength is poor, and postwelding also need carry out zinc-plated processing.Simultaneously, owing to be manual work, operator's labour intensity is big, and is high to operator's technical ability requirement.And production efficiency is low, can not satisfy the demand of production in enormous quantities.
Adopt traditional welding method, need carry out surface treatment: zinc-plated.Product after zinc-plated after after a while, particularly under the alternating hot and cold situation, can quicken the corrosion of zinc coat and come off (powdering comes off or bulk is peeled off) in machine oil, cause the decline of machine oil quality, oil circuit not smooth even stop up.Though passed through the oil filter filtration, but the reduction of oil, still can influence bent axle, connecting rod, camshaft, casing wall or the like critical component lubricated of engine, influence the operate as normal of engine, can cause scuffing of cylinder bore, seize when serious, even the scrapping of whole engine, also can influence the discharging of car load simultaneously, cause environmental pollution.
Summary of the invention
The purpose of this invention is to provide a kind of sump strainer soldering assembly method, it is big to solve the traditional welding method operation easier, and product design is not attractive in appearance, needs zinc-plated problem after the welding, thereby avoids descending because of the zinc pull-up falls, peels off the machine oil quality that is caused.
For reaching above-mentioned purpose, concrete scheme of the present invention is: a kind of sump strainer soldering assembly method, selecting cold-rolled steel sheet earlier is material, with traditional Sheet Metal Forming Technology moulding or the ring flange, supporting slice and the strainer body that press and make sump strainer, make the oil pipe of sump strainer with welded tube by necking forming technology, assemble as follows again:
A. with mouthful machine of upsetting ring flange is fitted in an end of oil pipe, and guarantees that fit clearance is between 0.01～0.03mm;
B. with mouthful machine of upsetting strainer body is fitted in the other end of oil pipe, and guarantees that fit clearance is between 0.01～0.03mm;
C. supporting slice is placed the oil-pipe external wall near described strainer body, the fabrication hole with pressing arc-welding machine spot welding supporting slice lower end fits tightly described strainer body and oil pipe, and contact-making surface is not less than 220mm
2, the welding current of described pressure arc-welding machine: 70～120A, arc voltage: 17～20V, gas flow: 10～15L/min;
D. selecting the fine copper silk for use is solder, and this solder is stuck in two part contact positions;
E. above-mentioned mounted sump strainer steadily is placed on and carries out furnace brazing in the brazing in controlled atmosphere stove, the technological parameter in the soldering is:
Intake pressure :≤0.1MPa
Liquefied ammonia inlet pressure: 0.6～1MPa
Welding temperature: 1140 °～1160 ℃ in proparea
Middle district: 1140 °～1160 ℃
Back zone: 1140 °～1160 ℃
Ammonia destruction furnace temperature: 800 ± 10 ℃
Ammonia decomposites mouth pressure: 0.5～1.0MPa
Ammonia decomposes rate of discharge: 2.5～3.0m
3/ h
Ammonia decomposes three district's flow: 1.5～2.0m
3/ h
Guipure speed: 900 ± 20 rev/mins;
F. appearance test detects size and range estimation outward appearance with the position cubing;
G. air-tightness detects, and detects soldering with air-leakage detector and air-tightness cubing and is under the 100KPa air pressure, keeps 1～2min not have leakage;
H. will detect satisfactory workpiece and put into oil sump and swing immersion oil and handle, and take out then and drain, the time of draining is 15～20 minutes;
Y. encapsulation, warehouse-in.
The specification of described solder is S2010.8 * 5/6 circle.
It is aviation antirust oil that described immersion oil is handled used oil.
The sump strainer that carries out soldering was fetched into the time of immersion oil between handling less than 10 hours from the brazing in controlled atmosphere stove.
Soldering is to adopt to make solder than the low-melting metal material of mother metal, weldment and solder be heated to above the solder fusing point and be lower than the temperature of mother metal fusing point, make the solder fusing, liquid solder soaks into mother metal, utilize capillarity fill the play movement and with mother metal mutually counterdiffusion realize connecting a kind of method of weldment.During soldering, solder is molten into liquid state and mother metal remains solid-stately, liquid solder infiltration, capillary flow in the gap of mother metal or on the surface, fills, sprawls, and interacts with mother metal, forms firm joint after the cooled and solidified, thereby mother metal is linked together.During soldering, the weldment heating-up temperature is lower, and the metal structure of weldment and mechanical property change little, and bulk deformation is less, and joint is smooth smooth, and technological operation and control are simple, the productivity ratio height.
The welding method that the present invention discards tradition adopts brazing in controlled atmosphere in the stove, can control heating-up temperature accurately.Because homogeneous heating, the deflection of workpiece is little, the weld smooth and beautiful appearance, and product is protected during soldering, and can be not oxidized.Through the product after the soldering, presentation quality is good, even weld, firm welding is attractive in appearance beautiful.And owing to no longer need zinc-platedly, the sequelae of having avoided the zinc pull-up to fall, peel off has improved the total quality of product.
