Abstract
The invention relates to the production process of cooling pipe for vehicles, starting with cutting aluminum bar with Phi100 into length of 380+- 5mm, heating it till 500-530deg.C, putting it to extrusion machine with special mold to compress the bar material with certain cross section, calibrating the extruded aluminum material, and cutting based on the required length, deburring and cleaning the residue inside and outside, with the product formed by tubes and oblique support barricades and up and below the tube being horizontal structures, both ends in arc structure, jointing part using arc transition. It is simplified in production process, good in molding plasticization, with finer molecule, reduced processes and dregs.
Description
Technical field:
The present invention relates to a kind of automobile charge air cooler in the technical field of transport facilities with cooling tube and production technology.
Background technology:
At present, automobile has become the main tool using of people in the traffic transport industry both at home and abroad, and the automobile charge air cooler plays a key effect to improving vehicle product quality as the automobile main parts size.Environmental pollution is one of universally acknowledged three big public hazards, and urban air pollution is very most of from emission of automobile wastes according to surveying and determination.The automobile charge air cooler reaches energy-conservation purpose except that having improved engine power after using on the automobile, also reduce the environmental air pollution problem that motor vehicle exhaust emission causes simultaneously.As the major function element, its traditional design is to adopt aluminium matter rectangle ratio-frequency welded tube or extruded tube to install the flow-disturbing slice structure additional to the automobile charge air cooler, assembles after soldering forms with cooling tube.Its main drawback is that high-frequency tube or spoiler adopt two-sided clad material production cost height, and it is low to install spoiler production efficiency in the assembling process additional, and fit tolerance requires high, and brazing flux applies difficulty, causes the brazing filler metal rate low.Soldering strength is poor, influences product service life, and therefore develop a kind of new automobile charge air cooler is new problem anxious to be solved both at home and abroad with cooling tube and production technology always.
Summary of the invention:
The purpose of this invention is to provide a kind ofly conceive science, production technology simplification, production efficiency height, low cost of manufacture, surface and cleaning inside degree height, fineness is good, structural strength is high, performance is good, good looking appearance, labour intensity are low automobile charge air cooler is with cooling tube and production technology.
The object of the present invention is achieved like this: the automobile charge air cooler production craft step one of cooling tube: with the aluminium bar fixed ruler cutting of φ 100, shearing length is 380 ± 5mm; Step 2: the aluminium bar of fixed ruler cutting is heated to 500-530 ℃; Step 3: will heat back scale aluminium bar on the aluminium section bar extruder, and squeeze out the rectangular section bar of certain cross dimensions with proprietary mould; Step 4: the aluminium section bar of extruding is calibrated, and cut off by Len req; Step 5: deburr, and cleaning surfaces externally and internally residue; This product structure is made up of body and bearing diagonal demarcation strip, and body is up and down two planar structures, and two ends, the left and right sides are arc structure, and 5-15 ° of bearing diagonal demarcation strip angle, thickness 0.2-0.3mm link to each other with body, and connecting portion adopts arc transition.
Main points of the present invention are its production technology and operation principle.Its operation principle is, the charge air cooler cooling tube adopts the one-time formed technology of hot extrusion to produce, and therefore, metal is by hot extrusion machine-shaping, and its plasticity is good, and distortional stress is little, the machining accuracy height; Metal by hot extrusion can make metal inside molecule grain refine, improves superficial density, improves surface smoothness, improves metal strength; Because a hot extrusion molding has reduced former spoiler and the interpolation brazing flux operation of installing additional, after the assembly soldering, has reduced inner residual brazing flux crystal of cooling tube and solder residue, has improved the cleaning inside degree greatly, and has increased structural strength.
The automobile charge air cooler compared with prior art has the design science with cooling tube and production technology, production technology is simplified, the production efficiency height, low cost of manufacture, surface and cleaning inside degree height, fineness is good, the structural strength height, performance is good, good looking appearance, labour intensity is low, metal is good by hot extrusion machine-shaping plasticity, distortional stress is little, the machining accuracy height, metal by hot extrusion can make metal inside molecule grain refine, because one time hot extrusion molding reduces former spoiler and the interpolation brazing flux operation of installing additional, reduce advantages such as inner residual brazing flux crystal of cooling tube and solder residue after the assembly soldering, will be widely used in the traffic transport industry.
