Fit forming device for integrated accessory connected with adblue tank

Abstract

The invention discloses a fit forming device for an integrated accessory connected with an adblue tank. The fit forming device comprises an adblue tank body and the integrated accessory of a pump connecting joint, pump mounting joints and a pump exhaust joint, wherein the integrated accessory is mounted on the adblue tank body. According to the fit forming device, the intra-mold fit process is adopted, the component integrating the pump mounting joints, the pump connecting joint and the pump exhaust joint is organically combined with the tank body, leakage of urea is avoided, safe and firm fixing of an urea metering injection pump is guaranteed, the structure of the adblue tank is optimized, the manufacturing process is simplified, the production efficiency is improved, the potential quality hazard is reduced, the quality consistency of finished products is improved, the production cost of the products is lowered, the integral strength and rigidity of the products are improved, and the stability of the adblue tank and a postprocessing system in the long-term operating process of vehicles is guaranteed.

Description

Technical field [0001] The invention relates to the technical field of automobile equipment, in particular to a pasting type device for connecting a blue tank and an integrated accessory. Background technique [0002] Tin Blue Tank, a special container for storing Tin Blue (a 32.5% urea aqueous solution, commonly known as Tin Blue) in the vehicle-mounted SCR exhaust gas aftertreatment system, generally made of stainless steel or plastic material resistant to corrosion by Tin Blue . The urea metering jet pump, temperature and liquid level sensor, exhaust device, filling device and other accessories should be installed on the blue tank. [0003] The accessories installed on the traditional blue tin can adopt screw mechanical connection, ultrasonic welding, overmolding and other methods. Screw connections need to add urea-resistant seals to prevent leakage; ultrasonic welding requires additional processes, welding equipment, poor welding appearance, and poor welding; overmolding has...

AI Technical Summary

Problems solved by technology

Screw connections need to add urea corrosion-resistant seals to prevent leakage; ultrasonic welding requires additional procedures, welding equipment, poor welding appearance, and possible poor welding; overmolding has flashes, poor coating, and the covered parts shrink at high temperatures and other defects, resulting in leakage of urea solution
