Abstract
The invention relates to an antirust process for a connecting rod of an automotive engine. The antirust process comprises the following steps of: cleaning the connecting rod in a cleaning room to remove oil dirt and scrap iron on the surface of the connecting rod; rinsing the connecting rod in a rinsing room and primarily oiling the connecting rod by using an antirust oil-doped cleaning solution; baking the connecting rod in a baking room, and evaporating excessive water content on the surface of the connecting rod, and coating atomized antirust oil on the connecting rod in a spraying and coating room. In the invention, the connecting rod is put in a material channel in a vertical manner, and is cleaned and oiled in a passageway in a spraying manner so as to keep a certain cleanness and a good antirust effect through the process of the four steps. The antirust process is simple and convenient to operate, and has an obvious effect; and when the antirust process is adopted, the requirement for the automated process is met, labor cost is reduced, and many costs for materials are also saved.
Description
Technical field
The present invention relates to a kind of auto parts and components manufacturing process, relate in particular to a kind of anti-corrosive technology that is used for connection rod of automobile engine.
Background technology
Connecting rod is the strength member in the automobile engine, and it is connecting piston and bent axle, and its effect is that the reciprocating motion with piston changes rotatablely moving of bent axle into, and passes to bent axle to the power that acts on the piston with power output.Because connecting rod plays very crucial effect in engine, therefore its dimensional accuracy and piece surface are required very highly, not only need part cleaning very, nothing is got rusty, and requires four connecting rods weight on the same group in each engine.
In reality was produced, connecting rod was processing in enormous quantities, and had begun to go up transfer matic production; Simultaneously because directly be sent to the power assembly assembling after the machined, so traditional handicraft often do not oil to the intact connecting rod of firm machined, if main engine plants' Direct Production connecting rod; Transport engine line to then assembles at once; Then because of preservation condition is good, inventory cycle is short, makes that part is not easy to get rusty; But in case connecting rod is paid main engine plants by parts factory, will relate to all kinds of stock's environment, and different traffic condition; And general connecting rod resting period long (general more than 45 days), connecting rod is prone to get rusty, and therefore need avoid problem of rustiness through oiling; Also the anti-corrosive technology of part is had higher requirement simultaneously, good like cleannes, sediment can not exceed standard; The first-class oil of connecting rod back weight will be consistent so that the correctness that last connecting rod weight is divided into groups can not adhere to other foreign matters etc.
Existing general antirust technology can oil through adopting heavy oil infiltration type equipment, perhaps manually brushes, mode such as spraying accomplishes; The former all is immersed in part to reach the comprehensive of connecting rod in the antirust oil and oils, and oils excessively but be prone to cause, and causes the connecting rod cleannes to exceed standard, the surface adhesion foreign matter, and bolt hole inner product oil causes moment of torsion to diminish, and connecting rod weight has big difference and can not combo etc.; The latter then can cause oiling inequality when oiling, and some position of part can't be oiled, and influences antirust effect.
In sum, traditional connecting rod rust-proofing method had both been wasted a lot of cleaning fluids and antirust solution, was not easy to realize automated production processing again, had had a strong impact on beat, and costs such as manpower and material are risen; The cleannes that too much cause that also possibly cause simultaneously oiling exceed standard, or the inequality that oils descends rust-proof effect; And piece surface adheres to booty easily and causes secondary pollution, and bolt hole amasss the generation of problems such as oil causes that moment of torsion diminishes.In view of the foregoing, nowadays press for connecting rod anti-corrosive technology on automatic assembly line is improved.
Summary of the invention
In order to solve the problem that above-mentioned prior art exists; The present invention aims to provide a kind of anti-corrosive technology that is used for connection rod of automobile engine; With reach make connecting rod can be comprehensive, automation antirust, and keep its cleannes, overcome the purpose of all inconvenience that anti-corrosive technology in the past brings.
A kind of anti-corrosive technology that is used for connection rod of automobile engine of the present invention, it comprises the following steps:
Cleaning step cleans said connecting rod in a cleaning room, removes greasy dirt and iron filings on the said rod surface;
Rinse step is carried out rinsing to said connecting rod in a rinsing room, utilize the cleaning fluid that is mixed with antirust oil that said connecting rod is tentatively oiled;
Baking step is dried said connecting rod in a baking room, evaporates moisture content unnecessary on the said rod surface;
The atomizing step that oils, the antirust oil with atomizing in a spraying room spreads upon on the said connecting rod.
At the above-mentioned anti-corrosive technology that is used for connection rod of automobile engine, in said atomizing oils step, in said spraying room, some atomizers are set; One metal oil conduit is connected with said atomizer respectively with a tracheae; Utilize a compression pump that said antirust oil is sent into said metal oil conduit until described atomizer, and make the said tracheae of external air source process until described atomizer, said antirust oil and compressed air are in the atomizer internal mix; With said antirust oil atomizing; Make to be full of mist of oil in the said spraying room that said connecting rod process in the spraying room makes mist of oil wrap connecting rod.
At the above-mentioned anti-corrosive technology that is used for connection rod of automobile engine, described anti-corrosive technology also is included in the preparation process of carrying out before the said cleaning step, and said some connecting rods are vertically put into the material road that is connected with said cleaning room side by side.
At the above-mentioned anti-corrosive technology that is used for connection rod of automobile engine; Described anti-corrosive technology also is included in carries out the said atomizing oily step of blowing after the step that oils; Some comb type nozzles are set in said spraying room; Utilize said comb type nozzle that external air source is injected on the said connecting rod, the unnecessary antirust oil of said rod surface is blown off.
At the above-mentioned anti-corrosive technology that is used for connection rod of automobile engine, the quantity of said some connecting rods is four, and the weight of every connecting rod is identical.
Owing to adopted above-mentioned technical solution, the present invention to make the connecting rod vertical direction put into the material road, with the method for Aisle type connecting rod is carried out fountain and clean and oil; Through the processing of four operations, make connecting rod can keep certain cleannes, and good antirust effect.The present invention is easy and simple to handle, and effect is obvious, has not only satisfied the automation process requirement, has reduced cost of labor, has also practiced thrift the cost of a lot of materials aspect simultaneously.
Description of drawings
