Problems solved by technology

The completion status of the substrate pretreatment process directly affects the quality of the composite material. In the past production process, the pretreatment process did not meet the requirements, resulting in poor bonding strength and consistent bonding strength of the produced composite material. Poor performance, high energy consumption and other issues
[0005] The pretreatment process in the existing composite material production process mainly involves the following pretreatment equipment structure. Usually, the base material pretreatment equipment uses electric heating tubes and plate heating to treat the oil and pollution of the base material. This type of heating source has uneven temperature. , consumes a lot of power, and the temperature difference of the base material here causes uneven internal tissue stress of the base material. When the base material passes through here, it will produce bursting ribs or beams, and the large deformation caused will destroy the mechanical properties of the base material and affect Product quality also brings a lot of trouble to the subsequent process
In addition, the heating method in the existing equipment is mainly to heat the substrate through air conduction and radiation, so that the electric heating energy cannot be fully utilized, and the unit energy consumption of the production product is large and the efficiency is low.

Abstract

The present invention relates to pre-treating apparatus and process for composite metal base material. The pre-treating apparatus includes one combined portal frame, heating guide rollers, one guide unit, one energy accumulator, one air blowing unit, heat collecting boxes and one hot blast circulator. During pre-treatment, the composite metal base material is made to pass through the heating guide rollers and the boxes separately in specific temperatures successively in certain linear speed. The present invention has the composite metal base material possess homogeneous heating, less heat deformation and no destruction of mechanical performance.

Description

technical field [0001] The invention relates to composite material processing, in particular to a pretreatment device and a pretreatment method for composite metal substrates. Background technique [0002] Composite materials are being used more and more in modern social life and production because of their incomparable advantages over other materials. Composite materials use metal substrates as the base band, and plastics and other materials are compounded on one or both sides of the base band. Facing the increasing demand for the quantity and quality of composite materials, how to accelerate the production of high-quality composite materials has become a common technology. The problem that people are trying to solve. [0003] In the current technical scheme of composite material production, there are a large number of composite material production equipment, because the production process of composite material is basically stable, and the general structure of the producti...
