Description
Technical Field
The invention belongs to the field of mechanical processes, and particularly relates to a vehicle door maintenance process.
Background
During urban rail vehicle frame overhaul, there is local situation of opening glue in guest room door plant crust, and prior art scheme has two kinds: firstly, riveting the glue opening position, and the defect that riveting holes are left on the outer side of the door panel after riveting, the original structure of the door panel is damaged, and the integral attractiveness of the door is affected; and secondly, the whole outer skin is removed, and the door skin is replaced, so that the defects that the door skin, the glass, the rubber strip and other car door accessories need to be removed simultaneously, and the door skin is bonded again, the construction is complex, and the cost is high.
Disclosure of Invention
In order to solve the problems, the invention provides a vehicle door maintenance process, which mainly solves the problems of high maintenance cost and damage to a door panel structure and improves the operation efficiency.
The technical scheme adopted by the invention is as follows: a vehicle door maintenance process comprises the following steps:
s1, cleaning residual glue in glue opening treatment: scraping and removing the gap at the glue splitting position by using a tool;
s2, fine ash and glue removal: spraying and washing along the slit by adopting a special spray irrigation cleaning agent to remove dust and residual glue inside the slit;
s3, shielding protection: protecting the periphery of the split door skin through a paper adhesive tape;
s4, bonding: inverting the glue opening position of the door panel, and dripping liquid special glue along the glue opening gap, wherein the glue is fully contacted with the glue opening door skin and the door frame;
s5, crimping: placing a mould matched with the shape of the glue opening position on a door plate of the glue opening position, and pressing the mould through an F clamp to keep the steel plate at the glue opening position completely attached to the bonding surface;
and S6, after the fixing is carried out for 12 hours, the clamp and the die are removed, the surface residual glue is cleaned, and the bonding condition is verified.
Preferably, the tool in step S1 is a steel ruler or a spatula or a flat shovel.
Preferably, the cleaning agent components in the step S2 include TMS azeotrope, stabilizer, and penetrant, and the drying time after the cleaning agent is used is more than 15 min.
Preferably, the main component of the special liquid glue in step S4 is cyanoacrylate, the viscosity is 500 ± 50mPas, and the bonding temperature is 5 ℃ to 30 ℃.
The invention has the beneficial effects that:
1. the door plate structure is not damaged, and the appearance of the vehicle door is not influenced after maintenance;
2. the construction process is simplified, the maintenance time is saved, and the maintenance cost is saved.
Drawings
FIG. 1 is a flow chart of a vehicle door repair process.
Detailed Description
The process flow of the present invention is further illustrated below with reference to FIG. 1:
the first embodiment is as follows:
a car door maintenance process comprises the following steps of firstly, cleaning the residual glue at the glue opening position: the gap at the glue opening position is scraped and removed mainly by tools such as a steel ruler, a scraper or a flat shovel and the like until the car door is visual without residual glue and the surface is basically smooth;
and the second step is fine ash and glue removal: adopting a special spray irrigation cleaning agent, wherein the main components of the cleaning agent comprise TMS azeotrope, a stabilizing agent and a penetrating agent, repeatedly spraying and cleaning the cleaning agent along the slit to remove dust and residual gum inside the slit, and drying for 15min after cleaning;
thirdly, shielding and protecting the part of the car door which is not coated with glue: sticking a paper adhesive tape around the adhesive-free door skin, exposing only the part needing adhesive coating, and protecting other parts by using the paper adhesive tape;
fourth, bonding: inverting the glue opening position of the door panel, and dripping liquid special glue along the glue opening gap, wherein the glue is fully contacted with the glue opening door skin and the door frame; in the embodiment, the main component of the special liquid glue is cyanoacrylate, the viscosity is 500mPas, and the bonding temperature is 20 ℃.
Fifth step, crimping: placing a mould matched with the shape of the glue opening position on a door plate of the glue opening position, and pressing the mould through an F clamp to keep the steel plate at the glue opening position completely attached to the bonding surface;
and after the crimping is finished, keeping for 12 hours for fixing, dismantling the clamp and the die, cleaning surface residual glue, and verifying the bonding condition.
Example two:
the basic steps and the used mould of the vehicle door maintenance process are the same as those of the first embodiment, but the relevant parameters are different: the airing time in the second step is 20 min; the viscosity of the special liquid glue in the fourth step is 450mPas, and the bonding temperature is 30 ℃.
Example three:
the basic steps and the used mould of the vehicle door maintenance process are the same as those of the first embodiment, but the relevant parameters are different: the airing time in the second step is 20 min; the viscosity of the special liquid glue in the fourth step is 550mPas, and the bonding temperature is 5 ℃.
After the three embodiments are maintained, the bonding condition meets the process requirements, and the door plate of the vehicle door has a good state and does not crack again through the test of vehicle three months of test operation.
The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art should be considered to be within the technical scope of the present invention, and the technical solutions and the inventive concepts thereof according to the present invention should be equivalent or changed within the scope of the present invention.
