Manufacturing method and production line for resin-coated aluminum pipe

Abstract

The invention discloses a manufacturing method for a resin-coated aluminum pipe. The manufacturing method for the resin-coated aluminum pipe comprises (S1) the stage of aluminum pipe supply, (S2) the stage of linearization of an aluminum pipe, (S3) the stage of drawing of the straight pipe, (S4) the stage of cleaning of the drawn aluminum pipe, (S5) the stage of imprinting of the cleaned aluminum pipe, (S6) the preheating stage of preheating the imprinted aluminum pipe through a non-contact induction heater, (S7) the coating and plating stage of continuously coating and plating the preheated aluminum pipe with synthetic resin containing primer in a glued mode, (S8) the stage of cooling the aluminum pipe subjected to glued coating and plating, (S9) the stage of pulling the cooled coated pipe, and (S10) the cutting stage of automatically cutting the pipe coated with the synthetic resin. According to the manufacturing method for the resin-coated aluminum pipe, all the procedures including the raw aluminum pipe supply stage, the imprinting stage, the glued coating stage and the automatic cutting stage are continuous and automatic, mass production can be achieved through automation, the productbility is improved, and the product quality can also be improved.

Description

technical field [0001] The invention belongs to the field of aluminum tube preparation, in particular to a method for manufacturing a resin-coated aluminum tube and a production line thereof. Background technique [0002] Generally speaking, various metal pipes are commonly used in household appliances, automobiles, construction, shipbuilding and other industrial pipes. For example: air-conditioning pipes for conveying refrigerants, refrigerator pipes, car freezer pipes, pipes for building systems, pipes for ships, pipes for facilities, industrial condenser pipes and hydraulic pipes, etc. At present, when using such metal pipelines, in order to prevent copper (Cu) pipes or other metal pipes from corroding, they must be used after gold plating, which is not only bulky but also expensive. In addition, due to the rise of international raw material costs and the supply and demand of raw materials, metal pipes are facing many difficulties. Therefore, compared with expensive and...

Problems solved by technology

However, the disadvantage of this type of method is that it still needs to use an adhesive, and the process is more difficult and complicated. At the same time, the adhesive force will decrease with the change of temperature, so that the adhesive force between the aluminum tube and the resin will decrease, resulting in the loss of all resins. Low durability of coated aluminum tubes
