Manufacturing technique and products of adopting casted hydroecium radiator

Abstract

The invention relates to a production technology adopting a casting water chamber radiator in technology field of the traffic conveyance and a product thereof, as well as a technique connecting a cast aluminum water box with a main leaf by an adopting argon-arc welding technique. The production process is that a cast aluminum water chamber is buckled at the inner edge of the main leaf of a core assembly and the upper part and the lower part of the cast aluminum water chamber is fixed with welding jigs in certain positions; 2-3 welding points exist between the cast aluminum water chamber and the main leaf; every weld length is 10mm to ensure the total size of the core assembly; workpieces are taken down after correcting and fixing the size of the assembly; a welding carried out is carried out for the long edge and the short edge of the main leaf respectively. The welding process is that AL-Si welding wires with Phi3.0 of diameter are adopted as welding rods. During the working process, AC welding arc with better controllability and aluminum alloy with a better carrying capability is adopted; the technological parameters needed to be controlled during welding are current, voltage and argon flow. The device of the invention is novel and scientific in design; the invention adopts the production technology in which the cast aluminum water chamber replaces an original plastic water chamber and argon-arc welding is used; therefore, the structural strength of product is obviously improved, thus meeting the using needs of heavy duty vehicles and motorbuses, having more reliable and stable sealing performance and reducing the production cost.

Description

Technical field: [0001] The invention relates to a production process and product using a casting water chamber radiator in the technical field of transportation tools. Background technique: [0002] At present, in the transportation industry at home and abroad, automobiles have increasingly become the main tools used in people's life and work. The radiator is an important component of the car engine cooling system. Its function is to ensure that the engine works at a suitable temperature and runs normally through gas-liquid heat exchange. At present, the water chambers of traditional aluminum heat sink products at home and abroad are all made of plastic materials (PV66 plus 30% glass fiber) through injection molding. The production process of the assembly product is as follows: After assembling the core assembly, put it into the furnace for brazing, then place the sealing rubber pad in the groove of the main piece at the end of the core, and buckle the plastic water chamb...

AI Technical Summary

Problems solved by technology

Its main disadvantages are low structural strength and short service life, especially for heavy-duty trucks. Due to the large size and heavy weight of the radiator, its press-fit bonding strength cannot meet the requirements of use under relatively harsh conditions, and its anti-vibration and anti-pulse pressure low performance
