Cooling water pipe for electric vehicle and production technology thereof

Abstract

The invention discloses a cooling water pipe for electric vehicle and production technology thereof, wherein a rubber pipe consists of an inner rubber layer, a fiber line reinforcement layer and an outer rubber layer from inside outwards. The cooling water pipe is prepared by the following steps of: (1) feeding rubber components of the inner and outer rubber layers into an internal mixer to mix the rubber components; (2) performing a fast testing on the semi-finished rubber after the rubber components are mixed; (3) putting the rubber into a 90 extruder with a straight machine head to extrude the inner rubber layer; (4) knitting a fiber line reinforcement layer on the extruded rubber layer of the inner pipe by using a knitter; (5) on the 90 extruder, extruding the semi-product in the step (4) out of the outer rubber layer by using a T-shaped machine head; (6) cutting the rubber pipe off and vulcanizing the pipe in a steam cylinder; (7) washing the rubber pipe and cutting the head of rubber pipe; and (8) performing injection molding and fast connecting the head to obtain the finished product. The production technology is simplified, the cost is saved and the operation is more convenient; meanwhile, the bonding is firm and the quality of product is good.

Description

technical field [0001] The invention relates to the field of auto parts, in particular to a cooling water pipe for electric vehicles and a production process thereof. Background technique [0002] Due to the development of the economy and the improvement of people's living standards, automobiles have become one of the means of transportation for people. With the continuous improvement of people's awareness of environmental protection and energy conservation, and the continuous rise of global oil prices, the automobile industry is looking for alternative energy sources. Low-carbon environment-friendly vehicles have become an alternative intermediate model, and electric vehicles, as low-carbon, environment-friendly and economical models, will be the future development direction of the automobile industry. The cooling system of an electric vehicle includes a radiator cooling system and an engine cooling system, in which a lot of cooling water pipes are used, such as between th...
