Description
Technical field
The invention belongs to motor bus, weigh the build-up member that truck is used, the radiator and the soldering processes thereof of the bus of particularly a kind of hydroecium and main leaf soldering, heavy truck.
Background technology
At present, motor bus, the heavy truck radiator of radiator, mainly by aluminum heat radiation core body, bring the upper tank at the mouth of a river into, take the lower header at the mouth of a river out of, a left side, the right plate side plate is formed, aluminum heat radiation core body wherein, its profile side of being body, it is by the aluminium main leaf, backplate, the heat radiation aluminum pipe, the heat radiation aluminium strip is formed, on side's body, the downside symmetry is established main leaf, a left side, the right side symmetry is established backplate, last, vertically be evenly equipped with several heat radiation aluminum pipes that spacing is impartial and be parallel to each other between following main leaf, between each two heat radiation aluminum pipe that adjoin mutually, connect folding heat radiation aluminium strip, and form the aluminum heat radiation core body of side's body; On the aluminum in the aluminum heat radiation core body, on following main leaf and the aluminum, junction between lower header, be to adopt argon arc welding to carry out seam to connect, left side at aluminum heat radiation core body, the right side connects a left side respectively, right plate, connect on the radiator plane of fan one side and protect solar or lunar halo, the recirculated water of refrigeration this moment engine enters in the upper tank from the water inlet of upper tank, disperse to enter each heat radiation aluminum pipe again respectively, these are dispersed in the circulating hot water in the heat radiation aluminum pipe, just be subjected to the refrigeration of fan cold wind, recirculated water after the refrigeration flows into lower header again respectively and enters engine through delivery port along pipeline, thereby realizes the purpose of the continuous refrigeration engine of radiator; Usually the Aluminium Radiator hydroecium is connected the welded heat radiator technology of motor bus, heavy truck with the main leaf seam, its process: comprise with aluminium sheet make the upper and lower main leaf of heat radiation core body and bring into, the upper and lower hydroecium of delivery port, clean, dry through ultrasonic wave, argon arc welding welding, core body pressure testing, hydroecium pressing, assembly experiments of sealing performance, assembly, oven dry, annex assembling, packing, warehouse-in.But wherein adopt the technology of argon arc welding welding, have following shortcoming:
Because the size for connection of the junction between upper and lower main leaf and the upper and lower hydroecium of aluminum is very little, and adopt argon arc welding to carry out the seam connection again, not only the intensity after the welding is low, dynamically yielding down, even fracture; In order to increase weld strength, have to carry out built-up welding at its weld seam and circumferential surface thereof, cause after argon arc welding, high and low uneven on the solder side of its junction, protruding, recessed injustice had both influenced the good looking appearance of product, again when argon arc welding, exogenous impurity is permeated in parent, and cause thermal conductivity to descend.
Summary of the invention
The present invention is intended to the shortcoming and defect part that exists in last art technology, and reasonable in design, simple is provided not only, weld strength can be improved, a kind of hydroecium of good looking appearance and the bus of main leaf soldering, the radiator and the soldering processes thereof of heavy truck can be increased again.
The objective of the invention is to realize: the bus of hydroecium and main leaf soldering with following technical scheme; the radiator of heavy truck; comprise aluminum heat radiation core body on; following main leaf; bring into; on the delivery port; lower header; it is characterized in that: last; following main leaf and last; junction between the lower header; to go up; following main leaf processing is the spill cross section; and the outer wall height in spill cross section is greater than the height of inwall; to go up; the linkage section of lower header is inserted in the spill cross section; and impose nitrogen protection weldering; make; following main leaf and last; be welded as a whole with brazing layer between the contact-making surface of lower header, make the end face that exposes of main leaf constitute smooth; smooth solder side.
The soldering processes of the radiator of described manufacturing hydroecium and main leaf soldering bus, heavy truck; its process: comprise with aluminium sheet make the upper and lower main leaf of heat radiation core body and bring into, the upper and lower hydroecium of delivery port; clean, dry through ultrasonic wave; welding, core body pressure testing, hydroecium pressing, assembly experiments of sealing performance, assembly, oven dry, annex assembling, packing, warehouse-in; it is characterized in that: the soldering processes of the soldering oven of nitrogen protection weldering are adopted in described welding, and its method of operating is in following:
A, oven dry: with workpiece in drying oven with under the temperature of 210 ℃ ± 2C through 0.1 hour the oven dry;
B, give heat: one, two, three districts in soldering oven---give the hot-zone, progressively workpiece is heated to 615 ℃ ± 2 ℃ from 210 ℃;
C, soldering: four districts---the weld zone in soldering oven, temperature is to be that 750～850mm/min carries out soldering welding with speed under 620 ℃ ± 2 ℃ in stove;
D, insulation: five districts---the heat preservation zone in soldering oven, in stove temperature be 625 ℃ ± 2 ℃ after 0.1 hour insulation, carry out the chamber and be chilled to room temperature, change next core body pressure testing operation over to.
Owing to adopted the nitrogen protection weldering, in soldering oven, once weld successfully, each solder bond place open is piled up.Argon arc welding in the prior art, its welding and assembling height only has 2mm, and adopts the soldering oven welding of nitrogen protection weldering can reach 8mm; Therefore, its weld strength improves widely.Combine the above technical measures of being taked, realize purpose of the present invention.
Advantages such as compared with prior art, the present invention is reasonable in design, simple not only, can improve weld strength, can increase good looking appearance again, and have the production efficiency height, and welding quality is good.
