Embodiment 1

[0039] See attached Figure 1-6 , The present invention is a partitioned solidification sticking method for riveting dissimilar adhesives, including the following steps:

[0040] Step 1. Take two sheets, the upper sheet 2 and the lower sheet 4, the upper sheet 2 and the lower sheet 4 have the same shape and size; and on the upper sheet 2 and the lower sheet 4 respectively There are through holes with the size of the aperture;

[0041] Step 2: Perform impurity removal pretreatment on the upper sheet material 2 and the lower sheet material 4 in step one;

[0042] Step 3: Adhere the plastic sleeve 3 to the center of the upper sheet 2 or the lower sheet 2 with a polymer adhesive to ensure that the area to be riveted is located inside the plastic sleeve 3;

[0043] Step 4. The plastic sleeve 3 divides the upper sheet 2 or the lower sheet 4 into two areas, the inner area of ​​the plastic sleeve and the outer area of ​​the plastic sleeve; two glues with different curing times are evenly coa...

Embodiment 2

[0053] The adhesive plate is riveted by a riveting method with rivets. The riveting device used includes a blank holder 6, a punch 7 and a lower die 8. The punch moves up and down in the central through hole of the blank holder; Heating mechanism and rivet transfer mechanism;

[0054] Step 1: Take two sheets, namely low-carbon steel plate and aluminum alloy plate. The structure and size of the low-carbon steel plate and aluminum alloy plate are the same, 80mm long, 40mm wide, and 1mm thick. And aluminum alloy plate, with through holes of aperture size;

[0055] Step 2: Perform impurity removal pretreatment on the low carbon steel steel plate and aluminum alloy plate in step one;

[0056] Step 3: Adhere the plastic sleeve to the center of the aluminum alloy plate with a polymer adhesive to ensure that the area to be riveted is inside the plastic sleeve;

[0057] Step 4. The plastic sleeve 3 divides the aluminum alloy plate into two areas, the inner area of ​​the plastic sleeve and the...

Embodiment 3

[0062] The difference between this embodiment and the second embodiment is that in step 4, the inner area of ​​the plastic sleeve 3 is coated with epoxy phenolic glue, and the outer area of ​​the plastic sleeve is coated with epoxy resin.

Abstract

The invention discloses a partition-curing adhesive riveting method for dissimilar adhesives, belongs to the field of adhesive riveting composite connection technologies, solves the technical problemthat the existing adhesive riveting technology does not fully consider influences of curing degrees of riveting regions on riveting, and uses characteristics of different adhesives to adjust the curing degrees of different regions of adhesive layers and improve the connection reliability of adhesive riveting parts, thereby ensuring that high-quality adhesive riveting joints are obtained; accordingto the invention, the inner area of a plastic sleeve and the outer area of the plastic sleeve are coated with the adhesives with different curing times respectively, when the adhesive layers in the outer area of the plastic sleeve are completely cured, the adhesive layers in the inner area of the plastic sleeve are in a liquid or solid-liquid mixed state, riveting is facilitated to obtain the high-quality adhesive riveting joints, and furthermore, the service life of each adhesive riveting part can be effectively prolonged.

Description

Technical field [0001] The invention belongs to the field of bonding and riveting composite connection technology, and in particular relates to a method for partitioning and solidifying and bonding dissimilar adhesives. Background technique [0002] The weight of transportation equipment such as automobiles, ships, airplanes, and spaceships has an important influence on its transportation performance and cost. Therefore, industries such as automobiles, ships, airplanes, aerospace, etc. need new connection technology. Under the premise of ensuring overall rigidity and crash resistance, replace traditional high-strength steel and other materials with lightweight materials to reduce their total weight and achieve lightweight body , Reduce energy consumption, improve transportation efficiency, and reduce production costs. [0003] Sticky riveting composite connection technology is one of the effective ways to achieve lightweight. Sticky riveting composite connection technology is to ...
