Problems solved by technology

[0003] In actual production, connecting rods are processed in large batches, and automatic production lines have already begun. At the same time, because they are directly sent to powertrain assembly after machining, the traditional process often does not oil the connecting rods that have just been machined. The factory directly produces the connecting rods, and then immediately transports them to the engine assembly line for assembly. Because of the good storage conditions and short inventory cycle, the parts are not easy to rust; but once the connecting rods are delivered by the parts factory to the main engine factory, various types of inventory will be involved. Environment, and different transportation conditions, and generally the storage period of the connecting rod is long (generally more than 45 days), the connecting rod is easy to rust, so oiling is required to avoid the rust problem, and at the same time, more requirements are put forward for the rust prevention process of the parts. High requirements, such as cleanliness is good, sediment cannot exceed the standard, the weight of the connecting rod should be consistent after oiling, so that the final connecting rod weight grouping is correct, and other foreign objects cannot be adhered to, etc...

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.

Example Embodiment

[0019] The specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.
[0020] See figure 1 , figure 2 , The present invention is an anti-rust process for connecting rods of automobile engines, which includes the following steps:
[0021] In the preparation step, four connecting rods 1 with the same weight are supported by the V-groove support structure 2 and placed side by side into a material channel 3, and the connecting rods enter the cleaning room 4, rinsing room, and drying room through the material channel 3. Dry room and spray booth 5;
[0022] In the cleaning step, the connecting rod 1 is cleaned in the cleaning room 4, and the shower nozzles 41 distributed around the connecting rod 1 are used to remove oil stains and iron filings on the surface of the connecting rod 1;
[0023] In the rinsing step, the connecting rod 1 is rinsed in the rinsing room, and the connecting rod 1 is preliminarily oiled with a cleaning fluid mixed with anti-rust oil;
[0024] In the drying step, the connecting rod 1 is dried in the drying room to evaporate the excess water on the surface of the connecting rod 1;
[0025] In the atomization and oiling step, the atomized anti-rust oil is applied to the connecting rod 1 in the spray booth 5; specifically, a number of atomization nozzles 51 are set in the spray booth 5, and the atomization nozzles 51 are distributed in the connecting rod. Above and below the rod 1, a metal oil pipe (not shown in the figure) and a gas pipe (not shown in the figure) are respectively connected to the atomizing nozzle 51, and a compression pump (not shown in the figure) is used to send the anti-rust oil The metal oil pipe reaches the atomizing nozzle 51, and the external air source is passed through the air pipe to the atomizing nozzle. The anti-rust oil and compressed air are mixed inside the atomizing nozzle to atomize the anti-rust oil, so that the spray booth 5 is filled with oil mist, The rod 1 passes through the spray booth, so that the oil mist wraps the connecting rod 1, so that the four connecting rods 1 can be oiled at the same time;
[0026] In the oil blowing step, a number of comb-shaped nozzles 52 are set in the spray booth 5, and the comb-shaped nozzles 52 are distributed above and below the connecting rod 1. The comb-shaped nozzles 52 are used to directly spray an external air source on the connecting rod 1, and The excess anti-rust oil on the surface of the connecting rod 1 is blown off, thereby maintaining the cleanliness of the connecting rod.
[0027] To sum up, the rust prevention process of the present invention is that the surface of the connecting rod is cleaner, quick-drying, and is not easy to adhere to stolen goods; and it can ensure that the four connecting rods are in the same group, and effectively prevent rust for more than 45 days, which not only achieves Automatic rust prevention also reduces labor costs, so it has the advantage of being more efficient; in addition, in the present invention, both the cleaning fluid and the rust prevention oil can be reused, thereby saving a lot of material costs. The connecting rod using the anti-rust process of the present invention is suitable for land transportation, sea transportation and other different transportation conditions, storage conditions of different climates, different temperatures, and different humidity, and has been verified to have a good anti-rust effect.
[0028] The present invention has been described in detail above in conjunction with the embodiments of the drawings, and those of ordinary skill in the art can make various changes to the present invention based on the above description. Therefore, some details in the embodiments should not constitute a limitation to the present invention, and the present invention takes the scope defined by the appended claims as the protection scope of the present invention.
