Problems solved by technology

However, the method for enterprises to make performance test boards for automobile coating glue is to scrape out the test boards by hand and then put them into production. Uneven, large randomness, irregularity, and poor consistency, so the actual correctness of the test data cannot be guaranteed, and the use requirements cannot be met, and it will cause great losses to the enterprise after it is put into production

Embodiment 1

[0043] Put the test plate 29 coated with electrophoretic paint (the size of the test plate 29 is: 0.8mm thick, 75mm wide, and 150mm long) on ​​the seat surface of the test plate seat 34, and use two feeler gauges with a thickness of 1.5mm, a width of 14mm, and a length of 100mm. The template 33 is respectively placed on the two sides of the test board seat 34 in the groove 34-1 symmetrically provided with on the test board seat 34, and a compression block 32 is placed on each template 33, and several compression bolts 31 The test board 29 is fixed on the seat surface of the test board base 34 through the pressing block 32 and the template 33 in the screw holes correspondingly provided on the test board base 34 by screwing.

[0044] Apply one of the skirt glues in the coating glue 44 evenly on the test plate 29, but the coating must be higher than the template 33. After stopping for 10 minutes, turn on the air source 1 to supply air, and the air source 1 is pressure-regulated an...

Embodiment 2

[0051] Put the test plate 29 coated with anti-sticking silicon (the size of the test plate 29 is: 0.8 mm thick, 75 mm wide, and 150 mm long) on ​​the seat surface of the test plate seat 34, and use a feeler gauge to superimpose a thickness of 3.5 mm, a width of 14 mm, and a length of 150 mm. Two templates 33 of 100 mm are respectively placed on the two sides of the test board seat 34 in the groove 34-1 symmetrically provided with on the test board seat 34, and a pressing block 32 is placed on each template 33, several The compression bolts 31 are screwed into the screw holes correspondingly provided on the test board base 34 to fix the test board 29 on the seat surface of the test board base 34 through the compression block 32 and the template 33 .

[0052] Apply one of the welding sealants in the coating glue 44 evenly on the test board 29, but the coating must be higher than the template 33. After stopping for 10 minutes, turn on the air source 1 to supply air, and the air so...

Abstract

The invention relates to a pneumatic rubber scraper and a method for producing an automotive coating rubber performance test board. A linear guide rail, two brackets, a scraper cylinder and a slider cylinder are fixed on a rack, a pushing magnetic switch II, a pullback magnetic switch II, a pullback magnetic switch I and a pushing magnetic switch I are respectively fixed on the scraper cylinder and the slider cylinder, a slider on which a test board seat is fixedly arranged is placed on the linear guide rail, the slider is connected with the slider cylinder, a scraper frame is connected with the two brackets, pull ears are respectively connected with the scraper frame and the scraper cylinder, a scraper holder on which a high-speed steel scraper head is fixedly arranged is connected with the scraper frame, and a spring is arranged between the inclined plane of the scraper frame and the surface of the scraper holder. The test board is fixed on the test board seat and is coated with a layer of coating rubber, an electric switch of a slider electromagnetic valve is started, the slider electromagnetic valve moves, and the slider cylinder is pulled back at a certain speed, so that the coating rubber on the test board can be scraped by the high-speed steel scraper head. The pneumatic rubber scraper and the method for producing the automotive coating rubber performance test board are characterized in that the standardization and the consistency of the scraped coating rubber performance test board can be guaranteed.

Description

technical field [0001] The invention relates to a pneumatic glue scraping machine and a method for making automobile coating glue performance test boards. Background technique [0002] Body painting is one of the most important processes in automobile manufacturing. After the welded car body runs to the painting line, it undergoes electrophoresis treatment, welding seam sealant, anti-stone chip coating, skirt coating and other processes, and then sprays the top coat After heat curing, the body can be put on a beautiful and beautiful exterior. If the coating adhesive has poor tensile stress and no application force, cracks and leaks will occur; the anti-stone impact adhesive and skirt adhesive have poor impact resistance and poor sound resistance, which will affect the performance of the car body and the surface paint. Cracks cause the whole vehicle to be unqualified. As a result, automobile manufacturers pay more attention to the requirements for glue used in coating lines...
