Abstract
The invention relates to a digging machine structural element coating method, which comprises the following steps: firstly, hanging a digging machine structural element for carrying out ball blasting treatment on the digging machine structural element; carrying out spraying supplementing treatment on the surface of the digging machine structural element after the ball blasting treatment; carrying out primer coating; subsequently, carrying out putty scrapping and baking the primer; carrying out fine grinding after the completion of the putty scrapping and the primer baking; coating finish paint; intensively cooling the finish paint after the casting baking; and finally, taking the digging machine structural element down from a frame. The invention is characterized in that the surface of the digging machine structural element after the spraying supplementing treatment carries out coarse grinding. The invention has the advantages that the phenomena of roughness, collision, scratch, oxide coating and the like can be solved, and the operating efficiency of the production line is improved.
Description
Technical field
The present invention relates to a kind of digging machine structural element coating method, belong to excavator Coating Pretreatment technical field.
Background technology
The digging machine structural element surface make with operation process in can produce unavoidably coarse, collide with, phenomenons such as scuffing and oxide skin, priming last as employing ball blast and the above-mentioned defective of blasting treatment.But that Shot Blasting can not thoroughly solve is coarse, oxide skin, collide with, problem such as convexity.In order to address the above problem, increase the attractive in appearance of structural member outward appearance, digging machine structural element can carry out large tracts of land usually and scrape greasy and fine grinding after adopting priming paint.Though scraping the greasy decorative appearance that can improve the coated article surface coating, can not improve the protective value of filming, and putty layer lacks flexibility, easy to crack, thus cause whole filming to be prone to be destroyed.Simultaneously, scraping greasy and fine grinding inefficiency, is a big bottleneck of the smooth and easy operation of streamline.
Summary of the invention
The purpose of this invention is to provide a kind of can solve coarse, collide with, the coating process of phenomenons such as scuffing and oxide skin and improve the operational efficiency of streamline.
In order to achieve the above object, technical scheme of the present invention has provided a kind of digging machine structural element coating method, the steps include:
Step 1, digging machine structural element is hung up, it is carried out Shot Blasting;
Step 2, to the processing that fills spray of the digging machine structural element surface behind the ball blast;
Step 4, carry out primer painting, scrape greasy subsequently and priming paint is toasted fine grinding after accomplishing;
Step 5, coating finish to cold by force after the baking of finish paint levelling, with the digging machine structural element undercarriage, is characterized in that between step 2 and step 4, having at last:
Step 3, roughly ground on the digging machine structural element surface of handling to carrying out filling spray.
The present invention increases before structural member priming paint and roughly grinds technology together.Roughly grind before adopting priming paint; Can control the structural member surface quality; Cause structural member rough surface, uneven, residual oxide skin, greasy dirt, the burr of not removing, welding slag etc. to polish to ball blast and after filling spray, this saves the extensive work time for back operation fine grinding comprehensively.Structural member is through after roughly grinding before the priming paint, and the surface is smooth, and is no coarse, do not have oxide skin and greasy dirt etc., can directly carry out the priming paint spraying.Can behind priming paint, do slightly to mend among a small circle after evenly roughly grinding to serious pit.
Advantage of the present invention be can solve coarse, collide with, phenomenon such as scuffing and oxide skin and improved the operational efficiency of streamline.
