Problems solved by technology

[0006] The present invention designs and develops a pre-adhesive curing sticking riveting process, which can overcome the separation of glue layer curing and riveting process in the existing sticking riveting process. When the curing reaches a certain degree of curing, the riveting is carried out, and the remaining curing is carried out after the riveting is completed. Fully consider The problem of the influence of bonding curing parameters on the riveting process

Embodiment 1

[0035] Step 1. At room temperature, pre-treat the upper and lower sheets to remove impurities, apply the polymer adhesive evenly on one side of the sheet for bonding, the thickness of the adhesive layer is 0.1-0.3mm, remove the excess around the sheet Adhesive, start curing; control the curing temperature at 80-200°C, stop curing when the curing degree is 0.18, and obtain the glued board;

[0036] In this step, the material of the upper and lower floor panels can be selected from metal and metal panels, metal and non-metal panels, non-metal and non-metal panels, as a preference, in the present invention, the upper and lower panels The materials are low carbon steel plate and copper plate respectively.

[0037] As a preference, the thickness of the adhesive layer in the present invention is 0.1mm, and the mechanical properties of the adhesive layer with this thickness are the best, because as the thickness of the adhesive layer increases, the mechanical properties gradually dec...

Abstract

The invention discloses a pre-bonding curing sticking riveting process which comprises a first step of performing impurity removing pretreatment on an upper layer plate and a lower layer plate, evenly coating one side of one plate with a macromolecular adhesive to perform bonding, causing the adhesive layer thickness to be 0.1-0.3 mm, removing redundant adhesive around the plate, and starting to perform solidification; when the curing degree reaches 0.18-0.45, stopping the curing, and obtaining a bonded plate; a second step of placing the bonded plate on a riveting platform, causing a blank holder to move downwards to be pre-tightened by a riveting plate, and preparing for riveting; a third step of causing the upper layer plate, the lower layer plate and the adhesive layer to be subjected to punch pressure to deform, causing the upper layer plate and the lower layer plate to snap each other; after the curing degree reaches 1, causing the adhesive layer curing to come to an end, and completing the sticking riveting connection process. By adoption of the pre-bonding curing sticking riveting process, the sticking riveting connection time can be shortened, sticking riveting processes are reduced, and working efficiency is improved.

Description

technical field [0001] The invention relates to a pre-glued and solidified sticky riveting process, which belongs to the field of sticky riveting composite connection process. Background technique [0002] The weight of transportation equipment such as automobiles, ships, airplanes and spaceships has an important impact on its transportation performance and cost and other index factors. Therefore, the automobile, ship, aircraft, aerospace and other industries need new connection technology. Under the premise of ensuring the overall rigidity and crashworthiness, replace traditional high-strength steel and other materials with lightweight materials, reduce the total weight of the body, and realize the lightweight of the body. , Reduce energy consumption, improve transportation efficiency, and reduce production costs. [0003] Adhesive riveting composite connection technology is one of the effective ways to achieve lightweight. Adhesive riveting composite connection technolog...
